To all whom it may concern:

Be it known that we, CHARLES J. LOFDAHL and CARL A. LOFDAHL, citizens of the United States, residing at Joliet, in the county of Will and State of lllinois, have invented certain new and useful lrnprovenients in Plane-Scrapers, and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to rnake and use the same.

This invention relates to certain new and useful improvements in a plane scraper and has for its primary object the provision of a device of this character which will be constructed in such rnanner that the blade may be readily adjusted at various angles and securely held in position.

Another object of the invention resides in the provision of a plane scraper of the above stated character which will be constructed so that the blade rnay be readily adusted to present a new edge when required, without the necessity of removing the blade and sharpening the same.

A further object of the invention resides in the provision of a wood scraper provided with an adjustable blade carriage in which the blade may be securely held against chattering thereby making it possible to obtain a much smoother dressed surface.

A further object of the invention resides in the provision of a wood working tool of the above stated character which may be readily employed by carpenters, cabinetmakers and other workmen and which will be light in weight, easy to operate and composed of the minimum number of parts.

With the foregoing and other objects in view as will appear as the description proceeds, the invention consists in the novel combination, arrangement and cooperation of parts as hereinafter more specifically set forth, claimed and shown in the drawings in which:

Figure 1 is a front elevation of the plane scraper.

Fig. 2 is a top plan view thereof.

Fig. 3 is a rear elevation.

Fig. 4 is a verticle section on the plane of line 4–4 of Fig. 2.

Fig. 5 is a vertical section on the plane of line 5–5 of Fig. 2.

Fig. 6 is a detail perspective of the blade carriage removed, and

Fig. 7 is a detail perspective of the nose cap, removed.

Referring more in detail to the drawings, in which sirnilar reference characters designate corresponding parts throughout the several views, 1 designates the wood bottom having the blade opening 2 formed therein and a nose cap 3 secured upon its rear edge, said nose cap 3 being preferably forrned of metal and having an inturned lower flange 4 resting in the seat 5 formed therefor in the wood bottom, with the lower face of the flange 4 flush with the lower face of the wood bottorn 1, as will be clearly understood by reference to the drawings.

The metallic frame 6 is mounted upon the upper face of the wood bottom 1 and has a pair of oppositely extended curved hand grips 7 projecting from the opposite sides of the frarne 6, it being understood that the frame includes upwardly extended. side members 8 from vvhich the handles 7, extend at the forward corners of said members 6.
The frame also includes a front upstanding rnernber 9 with a central socket 10 formed on the outer face thereof and withln which is threaded a set screw 11, the lower end of which is adapted for binding engagement with the adjusting pin 12, which latter is pivoted to the front plate 13 of the blade carriage, said adjusting pin 12 having sliding movement through the front blade 9 and socket 10 in order that the blade carriage may be readily adjusted at any inclined angle desired.

The front plate 13 of the blade carriage has rearwardly extending ears 14 curved by its side portions and through which are extended the opposite ends of a locking rod 15 having binding engagement with the outer or rear face of the back plate 16 of the blade carriage, downward movement of the back plate 16 being limited by the flanges 17 formed on the diverging upper portions of the sides of said back plate 16 and which flanges also serve to reinforce or strengthen the back plate. This back plate 16 has a threaded ear 18 in its uppermost central portion and through which extends the shank of the set screw 19 for engagernent with the rear face of the blade 20 positioned between the front plate 13 and back plate 16 to assist in retaining the plate 20 in proper position within the carriage. The front plate 13 also has an uppermost central portion with a threaded ear 21 opposite the ear 18 of the back plate 15 with a bearing screw 22 adjustably positioned therein to engage the blade 20 at a point practically opposite the portion of the rear face of the blade 20 engaged by the set screw 19. The front plate 13 of the blade carriage also has a pair of lower bearing screws 23 adjustably mounted therein for proper bearing engagement with the front face of the blade 20 near the bottom of the blade carriage to cooperate with the bearing screw 22 when the three bearing screws are properly positioned to prevent chattering of the blade 20 during the use of the tool particularly when the tool is moving on its return stroke previous to another operative or cutting movement of the tool over the work. ln order that the lower bearing screws 23 may be readily adjusted when required, without the necessity of removing the tool carriage, the upstanding front member 9 is provided with a pair of spaced openings 24 opposite the heads of the screws, 23, for the using of a screw driver or other instrument required to readjust the screws 23.

In order that the carriage for the blade 20 may be readily adjusted in various inclined positions, the carriage is mounted upon a pivot rod or hinge rod 25 which passes through hinge ears 26 depending from the forward lower corners of the front plate 13 of the carriage and connected by the lower outwardly and upwardly curved lower edge of the front plate 13, which also serves to properly inclose the hinge rod 25 and protect the same from shavings which may become caught around the same. The turned lower edge of the plate 13 is indicated by the numeral 27. The ends of the hinge pin 25 are mounted in the downwardly extended portion 28 of the frame 6, in the forward portion of the blade opening 22 of the wood bottom 1 and which portion of the frame 6 extends through said opening 2 with a part thereof presenting a smooth lower face flush with the lower face of the bottom 1, thereby providing a blade and bottom protecting wearing strip 29 in the forward side of the blade opening 2.

It will be understood that the frame 6 and nose cap tl may be secured to the wood bottom 1 by screws or any other suitable means. lt will also be readily seen that by loosening the set screw 11, the blade carriage may be readily moved on the hinge pin 25 to adjust the incline of the blade and in order to raise or lower the blade in the carriage or remove the blade therefrom, it is simply necessary to loosen the set screw 19 in the back plate 16.

From the foregoing, taken in connection with the accompanying drawings, the complete operation of this plane scraper and the advantages of the novel features thereof will be readily apparent to those familiar with this art. Further detail description of the device is therefor believed to be unnecessary.

While the preferred embodiment of the invention has been illustrated and described, many minor changes in the details of construction and arrangement of parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

What is claimed is :–

A frame, a rod spanning said frame, a front plate having a turned edge journaled on said rod, means associated with said plate and said frame to secure the plate in adjusted positions, ears extending from the plate, a rod mounted by said ears, a back plate intermediate said last rod and the adjacent portion of the front plate, flanges on the back plate resting on the second mentioned rod at one end, a blade intermediate the front plate and back plate of a width less than the width of the space between said plates, screws mounted by both of said plates and enagageable against the blade on opposite sides to vary the angularity thereof, and a screw on the front plate engageable with the blade to urge it against the back plate at a distance from the first mentioned screws.

In testimony whereof we affix our signatures in presence of two witnesses.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Hand-Scrapers, of which the following is a full, clear, and exact description.

My invention relates to an improvement in tools, and particularly to so-called hand scrapers such as employed for scraping or smoothing the surfaces of floors or other woodwork.

The invention relates more particularly to the body portion, which is constructed integrally of cast iron and is so designed as to properly hold the cutter in position for service.

It is the purpose of my invention to provide certain improvements in the construction of the body or frame, and by said improvements to overcome the errors and weaknesses existing in tools of this general description as heretofore constructed; that is to say, by the present design the user may grasp the tool in such a way as to apply his power with the greatest efficiency; the construction also being such that the handle portions are connected to the central body portion by a much stronger connection than that heretofore employed in an iron scraper body or frame.

In the accompanying is a perspective view scraper. Fig. 2 is a front elevation, partly in section. Fig. 3 is a rear elevation.

1 is the sole portion or base.

2 is an upwardly projecting wall arranged longitudinally of the base and between the front and rear edges.

3 is a slot which extends transversely through the base about midway betvveen the front and rear edges and just to the rear of the wall 2. The cutter, later described, projects through this slot, the slot being of an appropriate length for the cutter. The sole 1 and the wall 2 constitute the central portion of the scraper body or frame.

4–4 are handles which are arranged at each end of the central or main portion, the handles being cast integrally therewith, each handle being united to the central body portion in the unique manner now described. A description of the means for drawings, Figure 1 of my improved connecting one handle with the main body will suihce for both, as the means of connection corresponds in each instance.

5 is a curved flange connecting the inner end of the handle 4 with the side edge of the sole portion 1 forward of the wall 2.

6 is a curved flange connecting the inner end of the handle with the side edge of the sole portion 1 back of the wall 2.

7 is an upwardly curved flange connecting the handle with the side edge of the wall 2. These flanges operate in effect as longitudinally arranged strengthening ribs which extend far enough into the handle portion to constitute a very powerful connection. Each handle proper is in effect corrugated so as to get the maximum strength with the least weight, the corrugation being on the under side and appearing in Fig. 2 at the right hand side.

8 is a cutter blade.

9 is a clamping plate connected in any suitable manner, as by thumb screws 10–10 to the rear of the wall 2. This clamping plate 9 serves to hold the blade 8 firmly against the back of the wall 2, with the edge thereof projecting therethrough to the desired extent.

11 is a thumb screw which is located about midway in the wall 2 on the opposite side from the thumb screws 10–10. The inner end of this thumb screw 11 is arranged to engage the blade 8 to bend it slightly baclr at the center, as it is found that it operates more easily when thus buckled or bent.

In operation, the operator grasps the handles 4–4 with the fingers, while his thumbs project down into the spaces at the meeting angles of the front part of the sole, the front part of the wall and that part of the handle between the flanges 7 and 5. The ball of each thumb rests well down on the upper surface of the sole 1 very close to the work, so that the pressure of the thumbs will be applied to the greatest advantage, the position of the thumbs being such that a minimum of exertion is required of the operator, each thumb standing in a substantially straight position rather than being bent. Heretofore in the construction of iron scraper bodies it has been customary to provide a substantially vertical wall at each end of the sole 1, forming a box-like structure, thus requiring the operator to bend each thumb in order to get any thumb pressure directly on the sole. This is not only tiresome, but it is obvious that the operator’s full power cannot be applied when the pressure is exerted through the end of the thumb. It is apparent, of course that each handle curves upwardly so as to afford clearance for the fingers. In this, however, there is no novelty, as it is common in all scrapers of this general class.

In the old box-like type of construction above referred to, the connection between the handles and the main central body is comparatively weak, with the result that if the tool is accidentally dropped, breakage frequently occurs where one or the other handle is united to the main body. By the present invention I not only avoid the box-like structure due to the old end wall formation, but I also connect each handle with the main central body so that a maximum of strength is afforded, very much minimizing the danger of breakage. I have referred to that part of the main body which faces the operator as the front part. It will be understood that in operating the scraper the cutting stroke is performed ordinarily by pushing the tool away from the operator while pressing it firmly against the surface which is to be smoothed.

What I claim is:

1. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of longitudinally arranged rib-like flanges extending from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles.

2. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of longitudinally arranged rib-like flanges extending from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles, each handle being connected to the cutter opening by not less than three of said rib-like flanges, one of said flanges extending forwardly to meet the side edge of the sole forward of the wall, another extending rearwardly to meet the edge of the sole to the rear of the wall, another extending upwardly to meet the edge of said wall.

3. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of rib-like flanges extending longitudinally from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles, with means for holding a cutter against the rear surface of said wall.

To all whom it may concern:

Be it known that I, ANDREW EKMAN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.

My invention relates to improvements in scrapers for use in scraping and smoothing the surface of lumber, as in the manufacture of furniture, inside finish, &c., and its objects are: first, to provide a means for readily and securely fastening the scraper bit to place in such a manner that there will be no possible chance for it to tremble when being worked upon the surface of lumber, and, second, to provide a means whereby the scraper bit may be readily clamped to place by the use of an eccentric cam without danger of draiving the bit up from the desired position. I attain these objects by the mechanism illustrated in the accompanying drawing, in which —

Figure 1 is a front elevation of the scraper. Fig. 2 is a back elevation of the same. Fig. 3 is a top plan of the same, and Fig. 4 is a transverse section of the same on the line x x of Fig. 2.

Similar letters refer to similar parts throughout the several views.

In the construction of this scraper I make use of a frame A, having handles projecting sidewise from the bit-holding portion of the frame, somewhat after the form of an ordinary spoke shave frame. The bottom, a’ of this frame is thin and broad and has a slot through its center, as at a” in Fig. 4, for the passage of the edge of the bit B, and an integral girth a arranged to bear equally across the entire length of the force of the bit a short distance above the bottom a’ so that with the bit in its proper position, as indicated in Fig. 4, the back of the lower edge of the bit will bear against the bottom a’ with the scraping edge b projecting just far enough below the bottom of the frame to engage the wood being scraped, to the desired depth. To secure the bit to place I provide an eccentric cam C, having a short lever c integral therewith, for actuating the cam to press its edge against the surface of the bit its entire length, thus forcing the upper edge of the bit forward so that its hotly will be forced against the girth a in such a manner that the back surface of the lower edge of the bit will bear heavily against the edge of the bottom a’, in the slot a”, the entire length of the bit, thus readily clamping the bit to place and holding it so securely the whole length that it will be impossible for any portion of the bit to tremble or “chatter” and render the surface being scraped, rough and uneven. This cam may be flattened at the point so that the pressure of the bit against it will hold it to place to retain the bit firmly in position.

I provide for averting the danger of drawing the bit upward with the cam C, by securing a thin metal plate D to the frame in such a manner that one lip thereof will extend upward between the point of the cam and the surface of the bit, so that the movement of the cam when clamping the bit to place will act upon the surface of the plate D, thus having no effect upon the bit to draw it upward. Without this, or some equivalent appliance, this tool would be inoperative, or practically so, for the reason that it would be almost impossible to hold the bit to the desired position while clamping it to place with the cam C. The cam C is pivotally supported in the frame A by means of a rod passing through it and forming short gudgeons projecting from each end, as at c’, into corresponding holes in the frame, as indicated in Figs. 2 and 3, and has a short lever c projecting down from its longitudinal center, with which to actuate it for securing or liberating the bit, as hereinbefore described and as shown in Figs. 2. 3, and 4.

It will be noticed that the bit B, in this tool, inclines to the front, instead of to the back as with planes &c., which position is bit the finished than the cutting designed for use necessary to give to the results of a scraper rather results of a plane, it being after the plane has reduced the surface to as near a finished surface as is possible with a plane, and before the application of sandpaper for a final finish.

I find that the most convenient, and in fact, the only really practical way to pivot the cam C into the frame is to drill a hole through the side of the frame and the length of the cam and pass a rod through of suflicient length to engage the frame at both ends of the cam, in which case the rod must be securely clamped into the cam to avert the danger of its sliding endwise and one end becoming disengaged from the frame. Another object to be carefully provided for is to so place the cam, and so finish its bearing edge, the bearing edge of the girth a and the bearing edge of the bottom plate a’ in the slot a” that the corresponding portions of the bit B will have perfect contact the entire length of the several bearing edges here mentioned. To release the bit B for removing it from the frame, it is only necessary to throw the handle c of the cam C up to the position indicated by the dotted lines in Fig. 4 when the plate D will be released and the bit may be readily removed or inserted.

What I claim as my invention, and desire to secure by Letters Patent, is:

In a furniture scraper, a supporting frame, a thin bottom thereto having a longitudinal slot through it, a girth connecting the sides of the trains above the bottom plate, in position so that a line from the bearing b on the bottom directly across the bearing face of the girth will incline sharply forwad, a bit extending up from the slot to and some distance above the girth, a protecting plate secured to the bottom of the frame and extending up along the surface of the bit, and a cam pivotally secured in the frame in position to bear against the protecting plate and force the bit solidly between the cam and the bearing b in the bottom of the frame on one side, and the girth on on the other side.

To all whom it may concern:

Be it known that I, NOBLE KELLER, a citizen of the United States of America, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a certain new and useful Scraper; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a scraper and has among other objects, to provide a tool of this description, of simple and cheap construction which shall be efficient and durable in use and wherein the cutting blade can be readily formed, without the use of tools, other than those usually possessed by the user of the device.

It is also an object to provide a scraper that can be worked close up to any projection perpendicular to the surface on which it is used.

Another object is to provide means for easily adjusting the scraper blade.

A further object is to provide a scraper of such form that it can be readily grasped and pressure applied thereto without fatiguing the hands of the operator.

Still another object is to provide a scraper in which the blade need not be removed to sharpen the same.

One form in which this invention may be embodied, is herein described and is illustrated in the accompanying sheet of drawings, in which —

Figure 1 is a side elevation, and Fig. 2 is a rear elevation with portions broken away.

A handle 1 is fitted into a tubular socket 2, being retained therein by a pin or rivet 3. The rearward end of socket 2 has a downwardly deflected flattened portion 4, to which is attached by screws 5, a bolster 6, prefer-
ably formed of wood or other slightly yielding material. The lower portion of bolster 6 has a rabbet 7, which receives the upper portion of a blade 8, said blade being held frictionally between bolster 6 and a back plate 9, by means of bolt 10, which passes through a slot 9a in back plate 9, bolster 6, and downwardly deflected portion 4 of the handle, and has on its forward end, a nut 11. The sides of blade 8 may be beveled and sharpened in the same manner as the bottom of said blade. Blade 8 is preferably wider than back plate 9 and bolster 6. It may be formed of any convenient piece of sheet metal, such as an old saw blade, and there being no holes through it, it can readily be made with such tools as are usually carried by a wood worker.

The mode of operation of this invention is as follows: Handle 1 is grasped by one hand of the operator, while the other hand rests upon the top of bolster 6 and back plate 9. These parts being designed as shown, the hand rests easily upon this portion of the assembled tool and pressure may be applied without great fatigue to the operator.

The scraper is used by drawing it along the surface to be scraped, in the usual manner, as will be readily understood by those skilled in the art to which this invention appertains. In working close to vertical surfaces, the scraper may be laid upon its side and the ends of the blade used. In such use of the device, it will be readily understood that the handle extends away from the vertical surface, so that there is a sufficient clearance to enable the operator to manipulate the device conveniently. The blade 8 may be protruded, as it becomes worn, by striking on the upper sides of the projecting portions.

I claim:

1. A scraper comprising ahandle having a widened portion at the lower end thereof, a wooden bolster affixed to said portion, a back plate, said bolster and said plate suitably shaped to afford a hand-rest thereon when the same are assembled, a single bolt having a nut threaded thereon and passing through said plate, bolster, and widened portion of the handle, whereby the blade may be clamped between said bolster and said back plate.

2. A scraper comprising a handle, a metal tube affording a socket for said handle and having a flattened part bent at an angle to said socket, a wooden holster secured to said flattened part, said bolster shaped to afford a hand-rest thereon, and having a out-away portion to accommodate a blade, a slotted back plate, a single bolt having a nut threaded thereon and passing through said plate, bolster, and flattened part, whereby the blade may be clamped between the bolster and the back plate.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses at Los Angeles county of Los Angeles, State of California this 31st day of December A. D., 1907.

To all whom it may concern:

Be it known that I, WILLIAM ERDMANN, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new and Improved Scraper, of which the following is a specification.

My invention relates to certain new and useful improvernents in scrapers for dressing floors and the like, and the invention primarily has for its object to provide a scraper of an improved construction which can be easily and cheaply manufactured and which will readily and effectively serve its intended purposes. In my invention means are provided for holding and clamping the scraping blade, which means can be easily and quickly adjusted to permit insertion or withdrawal of the blade, as the case may be.

Another object of my invention is to provide a scraper having a yielding pad against which the blade rests to absorb or prevent vibration when the implement is in use.

The invention also embodies certain novel construction, combination and arrangement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which, —

Figure 1, is a perspective view of my invention. Fig. 2, is a central, vertical section thereof. Fig. 3, is a horizontal section on the line 3–3 of Fig. 2. Fig. 4, is a perspective view of the metallic gage and blade holding clamp member. Fig. 5, is a similar view of the stock and handle member. Fig. 6, is a perspective view of the bridge members.

Referring now to the accompanying drawings in which like letters and numerals of reference indicate like parts in all of the figures, 1 designates the stock with which the handles 1a merge, and the stock 1 has its under face plane, while its front face 1c is in a plane held at an obtuse angle to the plane containing the horizontal surfaces 1b of the stock.

Cemented or otherwise held in contact with the front face 1c of the stock 1, is a pad 2, of leather or other similar yielding material of substantially even thickness throughout, and against which the scraping blade 3 is held.

The blade 3 may be of the ordinary type and have the usual cutting edge 3a, as shown.

On the rear the stock 1 is formed with an elongated countersunk portion 1d to receive the bow shaped bridge member 4 and the set screw carrying bridge bar 5, the bar 5 having a threaded aperture to receive the set screw 6 and having its ends cut away as at 5b to form nut holding sockets.

The ends of the bars 4 and 5 have alining apertures 4a and 5a which register with the bolt holes 1x in the stock 1, to permit passage of the clamping bolts 7 which cooperate with the nuts 8, as shown.

9 designates the combined gage and blade holding clamp member which has the usual body 9a whose under face 9b lies in the same plane with that containing the face 1b of the stock 1. The body 9a has an upwardly projecting rear face 9c held at an acute angle to the face 9b and it also has upwardly projecting arms 9c having depressed blade receiving portions 9d and bolt apertures 9e together with a clearance space 9f to permit passage for the shavings.

In practice, the parts are arranged as shown in Figs. 1, 2 and 3. To loosen the member 9 and release the blade, it is only necessary to turn the set screw to ease up on the tension exerted on the bolt, when the blade may be easily withdrawn for sharpening or otherwise. When it is desired to reinsert the blade it is only necessary to replace the same in the position shown in Fig. 1, within the recesses 9d and tighten up on the set screw, thus exerting a tension on the bolts and drawing the member 9 against the blade, and tightly clamping the blade against the yieldable cushion or pad.

By constructing a scraper as shown and described, the same can be easily and cheaply manufactured at a minimum expense and the blade can be readily adjusted to its proper position as well as easily and quickly removed for sharpening, the provision of the yieldable pads serving to take up any vibrations which may occur during the operation of the implement and prevent chattering of the blade.

It will be noticed that the cut away ends of the set screw carrying bridge member 5 together with the countersunk portion of the stock 1 in which the bridge members are held, serve as a nut lock and prevent the nuts becoming loose, it being understood that the heads 7a of the bolts have their faces held at a slight angle to the longitudinal axis of the bolts, thus preventing turning of the bolt when the set screw is tightened up.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, opoperation and numerous advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.

What I claim is, —

1. The combination with the stock, the blade holding clamp member, and means for mounting the blade holding clamp member on the stock, of means carried by the stock and cooperatively connected with the aforesaid mounting means for causing the blade carrying clamp member to clamp the blade against the stock substantially as shown and described.

2. The combination with the stock, the blade holding clamp member having blade receiving recesses and the blade therein, of securing means passed through the clamping member and the stock for holding the clamping member to the stock, and means for tightening up or loosening said securing means to clamp or release the blade, substantially as shown and described.

3.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Scrapers, of which the following is a full, clear, and exact description.

My invention relates to improvements in scrapers.

The object is to facilitate adjustment of the parts and improve the construction so that it may be adapted to use under many different circumstances. I have sought to construct the parts so that they may be manufactured readily and assembled or taken apart without difficulty.

The preferred form of the invention is shown in the accompanying single sheet of drawings, in which —

Figure 1 is a side view of the scraper embodying the improvements of my invention. Fig. 2 is a front view of the same. Fig. 3 is a rear view of the scraper with the handle shown in section. Fig. 4 is a rear view of the back member of the head. Fig. 5 is a side view of the same. Fig. 6 is a plar view of a fragment of the handle.

The handle is preferably formed in two portions — a grip member 1 and a body member 2.

The head of the scraper carries the blade 3 and is preferably provided with an auxiliary grip or handle 4.

5 and 6 are the front and rear members, respectively, of the head, between which the blade is clamped.

7 is a screw located between the upper and lower ends of the plates 5 6. This screw passes freely through plate 5 and takes into plate 6, so as to produce, in effect, a hinged joint which may be adjusted to and fro to vary the widths of the space between plates 5 6.

8 8 are screws arranged at opposite edges of the plate 6 and screw-threaded therein. The ends of these screws project into cavities in the opposite face of the member 5, but are not screw-threaded therein. The function of these screws is to preserve the alinement of plates 5 6 and to act as spacers to guarantee the substantial parallehsm of said plate, whereby the ready substitution of blades 3 is permitted. The screws 8 8 also perform a stop function, the upper edge of the blade 3 taking a bearing against said screws so that blade will be projected uniformly from the clamping-jaws. These “stop-screws” 8 8, as we shall term them, may be shifted up or down on plate 6, there being a series of screw-holes a ong opposite edges thereof to permit this shifting of the screws to be made. By this means when blade 3 wears down or if a short blade is to be substituted the screws 8 8 may be moved to any one of the holes 8’, 82, or 83, so as to adapt the holder to the particular blade to be used.

9 is a main adjusting-screw having a stop-head whereby it may be easily operated. When approximate adjustment of the plates 5 6 has been secured by the adjustment of screws 7 and 8 and the blade inserted, the user may set up on screw 9 in such a manner as to powerfu ly clamp the blade 3. The rear of the back member 6 of the head is provided with a pair of lugs 10 10, to which the handle is pivoted.

11 is a curved arm extending from the rear of the back member and provided with a curved slot. This arm is preferably formed pf a separate piece of metal and riveted to the lug 12.

13 is a screw preferably provided with an enlarged head for engagement by the thumb and finger and by means of whic the handle is clamped to the arm 11. By this means the angle which the blade makes relative to the handle may be readily varied to suit the conditions under which the scraper is to be used. The parts, however, when clamped together are rigid, so that there is practically no vibration possible when the tool is in use.

What I claim is —

A scraper comprising a head portion formed of two parts, means for adjustably connecting the same at an intermediate point, said connection permitting said parts to swing, jaws formed by the edges of said parts at one slde of said connection, a clamp-screw at the opposite side of said connection, said clampmg-screw passing through one part and bearing against the other, and adjustable stop-screws at the opposite slde edges of said parts, and a handle hinged to one of said parts and means for adjusting the angle of said handle relatively thereto.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Scraping-Tools, of which the following is a full, cllear, and exact description.

My invention relates to improvements in woodworking-tools; and it consists in an improved scraper, the construction of which is such that it may be used, if desired, with an ordinary plane, merely substituting the same for the usual plane-iron. In this connection the device is capable of all of the adjustments to which the usual plane-iron is adapted and may be employed with an unusual degree of success.

In the accompanying drawings, Figure 1 is a longitudinal section of an ordinary plane-body fitted with my improved scraper. Fig. 2 is a perspective view of the scraper and scraper frame or carrier. Fig. 3 is a plan view of the same. Fig. 4. is a detail view of a clamping member.

I will first describe the scraper and scraper-carrier.

A is the scraper-blade, having the usual sharpened edge.

B B’ are two arms of the frame or scraper-carrier arranged to carry the blade A. As shown, these arms B B’ are arranged in the form of a wedge or a V — that is, the outer bearing-surfaces of the same form a V. The plane-iron A is clamped against the outer bearing-surface of the arm B by means of any suitabie clamping device — for example, the member C, carrying the clamping-screw C’. The arm B’ is so constructed and arranged that it may be readily applied to the plane-iron support or “frog” of a plane, the connection being preferably such that the various adjusting devices commonly found on planes will be available for the purpose of adjusting the position of the cutting edge of the scraper-blade in the throat of the plane. In the drawings, Fig. 1, I have shown the scraper-frame as it would appear in place on an ordinary plane. In this view, D indicates the main body of the plane. E E’ are the handles. F is the usual frog on the plane-iron support. G is the usual clamping- plate cooperating with the screw-post J. H I are adjusting-levers such as commonly employed in planes and by which the plane-iron may be given any desired adjustment. These levers need not be explained in detail, since their operation is well understood.

On referring to Fig. 1 it will be seen that the scraper-frame is clamped to the frog precisely as the ordinary plane-iron is clamped thereon, and the edge of the scraper-blade A will project through the throat or passage in the sole of the plane in the same manner as will the edge of the plane-iron, excepting that it will stand at a substantially different angle. The arm B of the scraper-frame is cut back or recessed transversely near its lower end, as indicated at K, to give a clearance back of the cutting edge of the scraper-blade. This is done to permit the cutting edge of the scraper to yield slightly and is productive of the most effective results in operation. While the scraper-frame is primarily adapted for use in connection with the plane, nevertheless the frame or carrier will itself afford a convenient grip when the scraper is used independently of a plane-body. The angle of the bearing-surfaces of the arms B B’ (indicated in the drawings) is that best adapted for the most successful results when the scraper is to be used in connection with the plane; but this angle, of course, may be varied to some extent at will. In the arm B’ of the scraper-frame a central longitudinal passage B2 adords clearance for the post J.

L is the usual cam by which the clamping-plate G may be set down hard, so as to hold the scraper-frame firmly on its seat.

What I claim is —

1. As an article of manufacture, a scraper attachment for a plane, comprising a body having two arms inclined relatively to each other, a scraper-blade, means for adjustably securing the scraper-blade to one of said arms, the other arm having a longitudinal recess and a transverse recess above said longitudinal recess, said recesses being adapted to accommodate mechanism of a plane for effecting lateral and vertical adjustment respectively.

2. As an article of manufacture, a scraper attachment for a plane comprising, a body having two arms arranged at an angle relatively to each other and furnishing two bearing-surfaces, one for contact with the plane-support, the other for the reception of a scraper-blade, a scraper-blade, means for adjustably securing the same to the said bearing-face, said bearing-face at and near the meeting angle of the two arms being recessed to afford clearance for the blade adjacent to its cutting edge.

To all whom it may concern:

Be it known that I, GEORGE DOIG SMITH, of Owen Sound, in the county of Grey and Province of Ontario, Canada, have invented certain new and useful Improvements in Wood-Scraping Tools; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a wood-scraping tool comprising a stock having a sole finished to form a perfect contact with the work to be operated on, a scraper-holding side inclining toward the sole at an angle less than a right angle, having a shaving-aperture inclining toward the sole, scraper-seats in the stock at each side of the shaving-aperture, a scraper mounted on the scraper-seats with its scraper edge projecting beyond the face of the sole, a yoke detachably connected to the stock, having projecting ribs to engage the scraper and hold it securely in position on the scraper-seats, and handles for the stock, by which the tool is operated, as hereinafter more fully set forth, and more particularly pointed out in the claims.

For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which —

Figure 1 is a perspective view of the tool. Fig. 2 is a perspective view of the stock with the scraper, yoke, and one of the handles removed. Fig. 3 is a perspective view of the yoke.

Like letters of reference refer to like parts throughout the specification and drawings.

The sole a, of the stock is perfectly smooth, so as to form a close contact with the work, and its scraper-holding side b inclines to the sole at an angle less than a right angle. In the middle of the scraper-holding side b is a shaving-aperture c, and in the stock at the sides of the shaving-aperture are scraper-seats d. Supported upon the scraper-seats is the scraper f and detachably fastened to the stock is a yoke g, having ribs h, opposed to scraper-seats to engage the rear face of the scraper and hold it securely against the stock. Between the ribs and the adjacent sides of the scraper and yoke is an unoccupied space g’ to permit the scraper to retain its natural elasticity. At each side of the stock is a handle k, by which the tool is operated.

In using the tool the edge of the scraper is adjusted to project slightly beyond the bottom of the sole, so that it will penetrate the material as the tool is drawn or pushed over it to scrape from the material a shaving of a predetermined thickness. The resistance offered by the material to the progress of the tool would naturally cause the displacement of the scraper if it were not held securely in position by the yoke or other clamping means, and by forming the yoke with the contacting ribs having the intervening space between them and the adjacent sides of the scraper and yoke unoccupied the scraper retains its natural flexibility and resiliency to produce a perfect finish on the material.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is —

1. A wood-scraper comprising a stock, the sole of which is finished to contact the surface of the material to be scraped and the scraper-holding side of which is inclined at an angle less than a right angle to the sole, a shaving-aperture in the scraper-holding side of the stock, scraper-seats at the sides of said aperture, a scraper mounted upon the scraper-seats, a yoke detachably connected to the stock having ribs to engage the scraper and hold it securely on the scraper-seats and an unoccupied space between said ribs and the adjacent faces of the scraper and yoke.

2. A wood-scraper comprising a stock, the sole of which is finished to contact the surface of the material to be scraped and the scraper-holding side of which is inclined at an angle less than a right angle to the sole, a shaving-aperture in the scraper-holding side of the stock, scraper-seats at the sides of said aperture, a scraper mounted up on the scraper-seats, a yoke detachably connected to the stock having ribs to engage the scraper and hold it securely on the scraper-seats, an unoccupied space between said ribs and the adjacent sides of the scraper and yoke, and handles connected to the stock.

_________________

To all whom it may concern:

Be it known that I, JAMES R. ELLIS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Wood-Scrapers, of which the following is a specification.

This invention is an improved wood-scraper for the use of carpenters and cabinet-makers, and is characterized particularly by improvement with respect to the manner in which and the means by which the scraping-blade is held in the stock and also by other improved details of construction, as will be more fully apparent from the following description.

In the accompanying drawings, Figure 1 is a front elevation of the tool. Fig. 2 is a rear elevation. Fig. 3 is a side elevation. Fig. 4 is a section on the line 4 4 of Figs. 1 and 2. Fig. 5 is a bottom plan view.

Referring specifically to the drawings, 6 indicates the back plate of the stock. This has a backwardly-extending foot 7, forming part of the face-plate of the tool. Said back plate also has at the top of its side edges backwardly-projecting ears 8 for attachment of the handles, which are indicated at 9. These handles are detachably secured to the tool by means of a rod 10, which is fast to one handle and fits snugly through holes in the ears and into the other handle, where its end is screwed into the nut 11. To remove the handles, it is simply necessary to unscrew the same and pull the rod out of the ears. This is useful in packing and carrying the tool. The front of the stock has two spaced upright portions 12, located at each side of the throat, which receives the blade 13. The uprights 12 are cast integrally with a forwardly-extending foot 14, which, with the foot 7, forms the face-plate of the tool, which slides over the work. This face is preferably slightly convex, so that the knife will take better into the work.

The blade 13 is gripped at its side edges between the back plate 6 and the uprights 12, and the foot 14 is cut away in front of the cutting edges of the blade, as at 15. The front and back pieces are held together and the side edges of the blade clamped therebetween by means of screws 16, which extend through the back plate into the upright parts 12 of the front.

To hold the knife at adjustment, a screw 17 extends through the back plate at the middle thereof, with its point bearing against the blade near the cutting edge. This screw serves to hold the blade at adjustment, and it also serves to slightly spring the knife forward at the middle, and this action is permitted by the recess 15 in front of the knife. This action is advantageous, and it is to permit the same that the screw 17 and the recess 15 are provided. The slight warp or curve in the knife produced by the pressure of the screw 17 produces a slight curve of its cutting edge, so that said edge takes the wood at a slight angle on each side with respect to the middle, whereby an easy cut is produced and chattering and stuttering is avoided. Furthermore, the cut can be adjusted within certain limits without loosening the blade, since the more the blade is bent forward by the screw 17 the deeper the cut will be. Variation in the angle of the blade is not possible, since its side edges are firmly clamped. The top end of the blade projects above the stock, so that the tool can be turned over and the top end used, if desired, as in rough work. In close quarters the handles can be removed and the scraper used without the handles.

What I claim as new, and desire to secure by Letters Patent, is —

1. The combination with a stock and face-plate, of a blade clamped at its side edges in the stock and extending through a throat in the face-plate, the latter being recessed in front of the blade, and an adjusting-screw bearing laterally against the back face of the blade, opposite the recess, and arranged to warp or curve the blade.

2. The combination with front and back plates, the back plate having ears at the side edges thereof, and a blade clamped between the plates, of removable handles extending laterally from said edges, and a screw-rod extending through the ears and connecting the handles.

3. The combination of front and back plates having respectively forwardly and rearwardly extending feet forming a face-plate, a blade clamped at its side edges, only, between the plates, the front plate being recessed in front of the blade, and an adjusting-screw extending through the back plate and bearing against the blade, and arranged to warp or curve the blade.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

To all whom it may concern:

Be it known that I, JOHN W. CARLETON, a citizen of the United States of America, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.

The embodiment of the invention illustrated and described herein is in the form of a scraper for use in scraping floors, &c.

The object of the invention is to permit of a wide adjustment of the handle with respect to the blade.

It is clear that the invention is applicable to other uses than to scrapers.

Referring to the drawings, Figure 1 is a side view of a scraper. Fig. 2 is a front view of the same. Fig. 3 is a rear view. Fig. 4 is a top view with part of the hand-rest broken away.

Referring to the drawings, A denotes the blade; B, a clamping-head having on one side a threaded pin C, which projects through a hole in the blade and is engaged by the thumb-screw D, which bears on a washer E. The rear of the clamping-head B has the lug F, one side of which is milled, as at f in Figs. 3 and 4. The handle G is provided with a disk H, one face of which is milled to fit the milling on the lug F. The handle is held to the lug by the pin J and the thumb-nut K. On the upper edge of the plate is located a hand-rest M, to which is secured a strap N, which enters a recess in the washer E to prevent the hand-rest from slipping side-wise off the blade. It is readily seen from the drawings that the handle is capable of adjustment in a plane at right angles to the blade by turning it on the pin J and securing it in place by the thumb-nut K, also that it is adjustable in a plane parallel to the blade by turning the handle and the clamping-head B about the axis of the pin C and maintaining it in position by means of the thumb-nut D. Thus I am enabled to so adjust the handle of the scraper that it may be used under any and all conditions — as, for instance, against the base-board when scraping a fioor. I am aware that other devices have been produced for accomplishing this object; but they are expensive to manufacture. They are difficult of adjustment.

The device herein shown and described is very inexpensive to manufacture and can be readily adjusted and used by any one.

I claim as my invention —

In combination with the clamping-head, a lug carried thereby, a pin oppositely disposed on said lug, and a handle adjustably connected to said lug, a blade mounted on said pin, a washer engaging the outer face of said blade, a locking means frictionally engaging the said washer, a hand-rest carried by the blade, and a strap carried by the said hand-rest and engaging a recess in the said washer, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Scraping-Tools, of which the following is a specification.

This invention relates to scraping-tools, adapted to be used for scraping or smoothing wooden surfaces — such, for instance, as surfaces of hard-wood or inlaid floors — and for other analogous purposes.

The object of my present invention is to furnish a simple, durable, and effective scraping-tool for the purpose above specified, and by means of which the scraping or smoothing of wooden surfaces may be executed with greater accuracy than is possible with the ordinary scraping-blade alone when used by hand, as heretofore common, and whereby the operation of scraping may be facilitated and rendered less tiresome to the workman.

In the operation of scraping wooden surfaces, as heretofore practiced, by means of a metal scraper-blade held in the hand, considerable difficulty has been experienced in holding the blade against the wooden surface with a uniform pressure from end to end of said blade, and to hold the blade at the required angle to secure good results and uniformity in work.

One of the chief objects of my present invention is to produce a scraping-tool that the ordinary workman may successfully manipulate and readily use in the operation of scraping or smoothing wooden surfaces, and to so construct and organize the parts of the scraping-tool that the scraper-blade may be adjusted and held at any desired angle relative to the plane of the surface being operated upon, and may be maintained at this angle during the entire operation without the exercise of skill upon the part of the workman, and whereby considerable power may be applied without material fatigue to the workman.

In the preferred form thereof herein shown and described my improved scraping-tool comprises a scraper-blade holder or frame embodying a clamp for holding a scraper-blade of said frame, a scraper-blade removably carried on said frame, a handle-bar or cross-bar preferably removably secured to the scraper-blade holder and having its ends projected beyond opposite ends of said holder, and a runner or tilting device preferably adjustably secured to the scraper-blade holder at an inclination to the scraper-blade holder and adapted for adjusting the blade to any desired angle relatively to any surface it is desired to operate upon.

In the drawings accompanying and forming part of this specification, Figure 1 is a plan view of a scraping-tool embodying my present invention. Fig. 2 is a front view of said scraper-tool as seen from the left hand in Fig. 4. Fig. 3 is a rear view of said scraper-tool as seen from the right hand in Fig. 4. Figs. 4 and 5 are end views, respectively, of the scraper-tool as seen from the right hand in Fig. 3 and showing, respectively, two different positions of the holder and scraper-blade relatively to a surface upon which the tool is supported. Fig. 6 is a rear view, similar to Fig. 3, of the scraper-blade holder and handle-bar with the adjusting-support, scraper-blade, and clamp-screws removed. Figs. 7 and 3 are side and edge views, respectively, of the scraper-blade detached.

Similar characters represent like parts in all the figures of the drawings.

The scraper-blade holder (designated in a general way by B) will usually consist of a rigid metal bearing-plate 2, having a plane inner face, which forms a bearing for the scraper-blade, and having a recess 3 in the outer face thereof, which forms a seat for the handle-bar H, which is seated in said recess, and is removably secured in place by means of a screw 4, which extends through the bearing-plate 2, as shown most clearly in Fig. 6 of the drawings.

The scraper-blade holder embodies a blade-clamp, which, in the preferred form thereof herein shown, comprises two depending clamp-arms 6 and 7, which are preferably formed integrally with the bearing-plate 2, one near each side edge of said plate, as shown most clearly in Figs. 1 to 6, inclusive, of the drawings. These depending arms overlap the plate 2 near the upper edge thereof, and have their inner bearing-faces slightly remote from, and in parallelism with, the adjacent bearing-face of the plate 2, as will be understood by reference to Figs. 4 and 5 of the drawings, the connecting portions 6’ and 7’, between the upper edge of the guiding-plate 2 and arms 6 and 7, forming abutments against which the upper edge of the scraper-blade S may abut for holding said scraper-blade against accidental vertical movement when in place between the depending clamp-arms and the bearing-face of the plate 2.

If desired, the clamp-arms 6 and 7 may be made resilient, and impinge the scraper-blade sufficiently to hold the same in place in the holder without the employment of clamp-screws; but for the purpose of positively holding the scraper-blade S in the holder B, I have shown the clamp-arms 6 and 7, provided with set-screws 8 and 9, respectively, which extend through screw-threaded holes in said clamp-arms, as illustrated in Figs. 4 and 5 in dotted line, and bear at their inner ends against the face of the scraper-blade S.

I do not limit myself to the particular construction of holder illustrated in the drawings, as the construction thereof may be modified within the scope and limits of my invention.

The scraper-blade S, which will usually be a flat sheet-metal plate, will preferably be slightly oblong in form, and will have the scraping edge beveled, as shown at 10, said blade being slightly greater in width transversely of its scraping edge than the distance between the abutments 6′ and 7′ and the lower edge of the bearing-plate 2 of the holder B, so that the scraping edge of the blade will project slightly beyond the lower edge of said holder.

As a convenient means for supporting the holder H and the blade S in the proper working position relatively to the surface (designated by the horizontal line C, Figs. 4 and 5) to be operated upon, and with the scraper-blade at the desired inclination or angle relatively to said surface, I have provided a support or runner, (designated in a general way by R,) which will preferably be adjustably secured to the scraper-blade holder B, so as to be capable of adjustment transversely of the plane of the scraping edge of the scraper-blade. This support or runner R, which may be referred to herein as the “adjusting-support,” is herein shown consisting of a rod or bar 12, carrying a roller 13 at the lower end thereof, adapted for resting upon the surface being scraped. This roller is shown carried between arms 14 and 14’ at the lower end of the bar 12, as shown most clearly in Figs. 1, 3, 4, and 5 of the drawings.

As a convenient means for adjustably securing the adjusting-support to the holder H at the proper inclination relatively to said holder and the blade carried thereby, I have shown the holder with a boss or bearing 15, formed at the upper edge thereof, approximately midway between the two clamp-arms 6 and 7, as will be understood by reference to Figs. 1 to 6, inclusive, of the drawings. This boss has a recess 16 formed therethrough, the axis of which intersects the plane of the bearing-face of the plate 2 of the holder, which recess is adapted to receive and permit a longitudinal sliding movement of the bar 12 of the adjusting-support. The degree of inclination of the recess 16 relatively to the plane of the scraper-blade carried in the holder will, of course, depend largely upon the requirements of the trade, the angle being herein shown as approximately one of thirty degrees, which I have found most convenient for general use.

As a means for adjustably securing the adjusting-support R in the bearing 15, and as a means for holding the same against rotation, I have shown the bar 12 of said support having one flat portion 18, and have shown the recess 16 of a cross-sectional shape corresponding to the cross-sectional shape of said bar, the bar being held in adjustable position in the bearing preferably by means of a set-screw 19, which extends through the boss or bearing 15 and bears at its inner end against the flat side of the bar 12 of said adjusting-support.

It will be obvious that the means for adjustably securing the adjusting-support R to the holder and the particular construction of said means and support may be variously modided without departure from my invention.

The handle-bar H is herein shown extended beyond the side of the holder B and provided with handles or knobs 20 and 20′ at opposite ends thereof, which may be grasped by the workman when manipulating a scraper-tool. This handle is made removable, so as to enable the workman to detach the same from the scraper-blade holder when it is desired to use the tool for scraping corners, &c.

When it is desired to change the inclination of the scraper-blade S relatively to a surface, as C, it is simply necessary to loosen the set-screw 19, which clamps the bar 12 of the adjusting-support R, and slide said bar upward or downward longitudinally in the bearing 15, and secure the same in adjusted position by said set-screw 19, which will increase or decrease the angle of the scraper blade and holder relatively to said surface, as will readily be understood by comparison of Figs. at and 5 of the drawings.

Having thus described my invention, I claim —

1. A scraping-tool comprehending a scraper-blade holder and a runner adjustably connected together at their upper ends for adjustment, one relatively to the other, in an intersecting plane, and diverging from their points of connection toward their opposite, lower ends; and a scraper-blade removably carried by the holder with its scraping edge extending below the lower end of the holder.

_________________

To all whom it may concern:

Be it known that I, EDRICK GOWDY, a citizen of the United States, residing at Ansonia, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Devices for Setting the Edges of Plane-Bits and other Tools; and I do hereby declare the following to be a f ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object the production of a simple and inexpensive device which may be readily carried about in a tool-box, and which will act to turn forward slightly the edges of plane-bits and other tools. I have found in practice in planing all classes of wood, it being particularly true in the case of knotty close-grained woods, that by turning forward the edge of the bit of the plane I can secure very much better results in the way of a line smooth finish, avoid all danger of chipping out, and can retain the plane-bit sharp and in good condition for use much longer than when the edge is left to project downward in a line with the front of the blade in the usual manner; and in order that I may set the edges of plane-bits without inconvenience and at any time I have devised the simple and novel tool of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to denote the several parts.

Figure 1 is a perspective of my novel tool, showing also a portion of a plane-bit at the angle at which it is passed over the turning-piece; Fig. 2, a longitudinal section of my novel tool, showing the turning-piece in elevation. Fig. 3 is an elevation on a greatly-enlarged scale of the lower end of a plane-bit, showing the edge turned forward as after it has been acted upon by my novel tool; and Fig. 4 is a section similar to Fig. 2, showing a slightly-different mode in which I have carried my invention into effect.

1 denotes a block, preferably made of wood, which is provided with a hole 3, bored into the block from either end near the top of the block and adapted to receive a round piece of metal 4, which I term a “turning-piece.” This turning-piece is preferably made of chilled steel, and is made slightly larger than the hole, so as to require to be driven therein and remain firmly wherever it is placed. It will be noticed that hole 3 is made near enough to the top of the block so that the upper portion of the hole is open. This permits the rounded surface of the turning-piece after it is driven in to project slightly above the surface of the block, as is clearly shown in the drawings. In practice I preferably drive a plug 2 into the hole after the turning-piece has been driven in and smooth it off level with the top and end of the block, so as to give a neat finish to the tool. For convenience in driving the turning-piece out, should it be required, I preferably provide a hole 5, which extends into hole 3 from the other end of the block. Should the turning-piece become worn or nicked in use, it may readily be driven out, given a partial rotation to place another portion of the rounded surface in operative position, and then driven back to place and the plug driven in after it.

In use, after sharpening a plane-bit or other blade, the operator takes the blade firmly in his hand, holding it at about the angle indicated in the drawings, and passes it backward and forward over the turning-piece one or more times, as may be required. The action of the portion of the turning-piece lying above the surface of the block will be to turn the cutting-edge forward slightly, as shown in Fig. 3. In Fig. 4 I have shown the block as provided with a transverse undercut groove 7, the undercut side of said groove being the forward side, which is made perfectly straight, but is inclined downward and inward. The hole to receive the turning-piece is lower down in the block and is intersected by the groove, the rounded surface of the turning-piece lying about the same distance above the bottom of the groove that it does above the surface of the block in the other form. In using this form the operator passes the blade, the edge of which is to be turned through the groove and over the surface of the turning-piece one or more times in the same manner as in using the other form.

In order to hold the block firmly in place and make the tool convenient in use, I provide two or more sharpened prongs 6, which project downward from the bottom of the block to engage a work-bench or plank and hold the block firmly in place when it is desired to use the tool.

Having thus described my invention, I claim —

1. A tool for setting cutting-edges, consisting of a, block having a, rounded turning-piece driven therein, the upper portion of which extends slightly above the surface of the block, so that a, cutting-edge passed over the surface of the block will engage the rounded surface of the turning-piece and be turned slightly forward, as and for the purpose set forth.

2. A tool for setting cutting-edges, consisting of a block having a rounded turning-piece driven therein and extending slightly above the surface thereof, and prongs upon the under side thereof, whereby the block may be held in place in use.

In testimony whereof I afflx my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, JOHN A. KEISER, a citizen of the United States,and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cabinet-Scrapers, of which the following is a specification, reference being had to the accompanying drawings forming a part hereof.

My invention relates to an improved cabinet-scraper.

Figure 1 is a top plan view of my improvement. Fig. 2 is a bottom plan view of the same; Fig. 3, a section on line x x, Fig. 1; Fig. 4, a perspective view of the pivoted clamp; Fig. 5, a section on line z z, Fig. 1.

A A’ represent the handle of the scraper. The stock of the tool is composed of the following parts.

B b represent the face of the scraper; C, a slot separating the faces in which the cutter is set.

D represents a ledge, against which the cutter c is clamped. This ledge is rigidly attached to the face B, the parts forming an L, as shown in Fig. 3. F represents the ends of the stock, from which the handles A A’ spring, as shown in Figs. 1 and 2.

E e represent arms forming a part of the end plates of the stock F, for firmly holding face b rigidly in a plane parallel with face B.

G represents a pivotal clamp for clamping the knife c against the ledge D. This clamp is suspended on pivots a to the end plates ofthe stock F, passing through ears d of the clamp G.

H represents a lever-arm extending upward a considerable distance above the pivots of ears d.

I represents a set-screw tapping through the arms H, the point of which bears against the ledge D and forces the lower edge of clamp G against the cutter c at its lower end, and firnily clamps it against D.

This tool is very cheap, strong, and efficient. The cutter c works clear to the ends of face B b, and is a decided improvement over the tool shown in Letters Patent granted Samuel C. Tatum & Co., my assignees, June 10, 1884, No. 300,266, and other tools for the same purpose hitherto used.

Instead of screw I, a cam may be used to operate the clamp, and would be the equivalent therefor.

I do not broadly claim a stock having rigid faces separated by a slot, and the front face strengthened by arms forming part of the ends of the stock; nor do I claim, broadly, a cutting-bit attached to an oscillating plate adjustable by a thumb-screw and spring; nor a spokeshave having a bearing-surface in front of the cutter applied by a lever having an adjusting-screw for regulating the width of the month, the thickness of its cut, or the shaving; and I do not broadly claim the bearing-surface of a stock provided with a ledge or flange serving as a bearing for the cutting-bit.

I claim —

1. A cabinet-shave consisting of the stock F, rigid faces B b, separated by slot C, the part b being braced by arms E e, forming part of the end plates of the stock, ledge D, and cutter c, clamped against the ledge, substantially as described.

2. A cabinet-shave consisting of the stock F, rigid faces B b, separated by slot C, ledge D, and clamp G, pivoted to stock F, and adapted to clamp a cutter, c, against the ledge D, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand.

To all whom it may concern:

Be it known that I, JOHN A. KEISER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lmprovements in Cabinet-Shaves, of which the following is a specification.

My invention relates to an improved cabinet-shave, and other similar tools.

The object of my invention is to provide ready means for removing or inserting the bit or knife, all of which will be fully set forth in the description of the accompanying drawings.

Figure 1 is a perspective view of my invention with the bit removed. Fig. 2 is a front elevation of my improvement with the bit in position for use. Fig. 3 is a bottom plan view of Fig. 2. Fig. 4: is a vertical section on line x x, Fig. 2.

A A represent the handles of my improved shave.

B represents the central portion of the stock of the shave, which, with the handles, is preferably made of malleable iron, cast in one piece. a represents ears cast on and with the stock B.

C represents the swiveling or detachable bit-face; C’, the stationary bit-face, which forms a part of the stock B.

b represents ears attached to the face C, and provided with pivots i, which hinge the ears b to the ears a.

d represents a yoke or bar connected to the ears b.

The parts C, b, b, and d are made of metal formed in one piece, and arranged so as to more freely upon the pivots i.

D represents a cam connected by pivot c to the center of the yoke d.

E represents the bit or knife, which is made to fit into the head B, as shown in Figs. 2 and 4. In order to hold the knife in position by detachable fastenings, it is essential to have it gripped at two points — first, at or near the cutting edge, and, second, at the central point of the knife, sufficiently near the upper end to prevent its rocking or moving. To accomplish this I provide lugs h, at each end of the cutter E on the bottom of face C, and adapted to bear against the cutter E upon each side of the shaving-slot L.

The mode of operation in inserting the knife is as follows: Fig. 1 represents the device with knife or bit removed from the stock of the shave and the cam D hanging loosely upon the yoke d. The knife E is inserted with the proper feed, (the edge depending below the faces C C’,) and cam D is turned upward so as to bring the shoulder against the face ofthe knife. This movement draws the lugs h, on the face C firmly against the blade E, pressing or gripping it tightly against the face C’ of the stock by the inward movement of the face C, caused by the pressure of the shoulder of cam D against the upper end of the knife, forcing the yoke d outward. This mode of constructing the stock and attaching the parts holds the knife firmly in position, and yet allows it to be instantly inserted and removed.

The principal feature of my invention consists in constructing the pivoted portion of the stock so as to grip the knife near the cutting-edge, and central at or near its upper end, and at the same time not be apt to become accidentally disconnected from its bearings.

An inferior modification of my invention would be to employ a thumb-screw passing through the yoke d, instead of the cam D, for gripping the upper end of the knife E. Such a construction would be covered by the first and second claims herein. Spokeshaves and other tools could be made in a similar manner as the within-described cabinet-shave. Another modification could be made by having the lugs h, attached to the face C’ and the shaving-slot in the same side of the bit-face. So, too, one lug h might be employed near the center of the bit-plane; but it would not be as efficient as the plan here shown.

I claim —

1. A shave composed of the stock B and bit-face C’, in combination with the bit-face C, swiveled by a pintle placed parallel with the axis of rotation of the bit-face, and a fastening device, D, suitably supported, and adapted to grip the bit at or near the top and force one of the bit-faces against the lower edge of the bit, whereby the bit will be held to its place by said fastening D and bit-face, independently of other fastenings, substantially as described.

2. The combination, with the stock B and stationary bit-face C’, of the bit-face C, provided with lugs h to bear against the bit and with yoke d, and swiveled by a pintle parallel with its axis of rotation, and a fastening device, D, connected with the yoke d and adapted to bear against the upper part of the bit, the bit being held to its place by said fastening D and the face C, independently of other fastenings, substantially as described.

3. The combination of the stock B and stationary bit-face C’, provided with ears a, the bit-face C, provided with ears b and yoke d, and swiveled to ears a by pintles i, and the cam-lever D, fulcrumed on yoke d, for instantaneonsly fastening and releasing the bit, substantially as described.

In testimony whereof I have hereunto set my hand.

_________________

To all whom it may concern:

Be it known that I, HENRY D. SPICKLER, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Wood- Scrapers; and that the following is a full, clear, and exact specification thereof, which will enable others skilled in the art to make and use the said invention.

My invention relates to the construction of a tool for scraping and smoothing the surface of wooden implements, such, for instance, as ax-handles, spokes, &c., after they have been worked into the desired shape by means of a lathe or other machinery for accomplishing that object. It consists of a metal frame, having a handle cast or otherwise attached at each end, and having two longitudinal slots, in which are secured knives with scraping-edges, one of a straight and the other of a curved form, which are arranged at such an angle with the bottom faces of the frame, and with their edges at such distances from said bottom faces, as to cause the said knives to act as scrapers on the article to be operated on, when the tool is drawn over said article after the manner of using the ordinary spoke-shave. This scraper is applicable to nearly all the uses to which the common plate scraper is applied, while it is much easier to operate and does better work than the common scraper.

In the accompanying drawing, Figure 1 is a top view of the scraper; Fig. 2, a bottom view of the same 5 Fig. 3, a view of that side of the scraper used for curved surfaces; Fig. 4, a view of the side used for straight surfaces; and Fig. 5, a vertical cross-section of the same.

A is the metal frame, having handles a a cast on it. D and E are knives inserted in slots F F, and having their edges d and e turned forward, like the ordinary scraper, the knife E having a curved lower edge, e, while the edge d of the knife D is straight. The knives D E are held firmly in place by means of the wedges f f driven into holes in the frame, the edges of said knives projecting slightly below the bottom-faces B C of the frame. The slots F F in which the knives are placed are made of a triangular section, to receive the scrapings thrown up by the knives. The base of the frame A is inclined from the middle toward the sides, as shown at B and C, Figs. 2 and 5, the face being also curved longitudinally, to correspond to the shape of the knife E, and adapt it to use on curved surfaces. On applying either knife to a wooden surface, the inclination of the base inclines the knife, so that the angle D d c or E e b formed by the knife with the surface toward whichit is moving will be less than a right angle, the acuteness of the angle depending on the amount of inclination of the base, by which means the scraping or turned-up edges d e of the knives are brought at the proper angle to act on the wood, as will be readily seen.

In using the scraper, the operator draws the tool over the wood with the knife d forward, when he wishes to use the straight cutting-edge, and in the opposite direction when the curved edge e is desired, only one cutting edge being in operation at one time, as will be seen from the form of the cross-section shown in Fig. 5.

I lay no claim to a scraper constructed with a single scraping-knife, as such device has been heretofore shown in Letters Patent granted to F. A., J. H., and D. C. Williams, July 24, 1866, No. 56,651, and I confine my claim to a double scraper, having a straight knife on one side and a curved knife on the other, as herein shown.

What I claim as my invention, and desire to secure by Letters Patent, is —

The double scraper herein described, consisting of a frame, A, with handles a a, in which are secured two knives, D E, with turned or scraping edges d e, said knives being arranged back to back, and on opposite sides of the frame A, and one of said knives, D, having a straight, and the other knife, E, a curved edge, substantially as and for the purpose specified.

As evidence of the foregoing, witness my hand this 4th day of November, A. D. 1872.

_________________

To all whom it may concern:

Be it known that I, JOSEPH JONES, of Newark, in the county of Essex and State of New Jersey, have invented an Improvement in Scraping-Planes, of Which the following is a specification:

This invention relates to that class of implements used in smoothing the surface of hard wood and other hard material, known as scraping-planes; and it consists in the combination, with the holder which carries the scraping-tool and with suitable slotted supports arranged at the sides of the stock, of a transverse bolt and a locking-nut, in such manner that the scraping-tool may be adjusted at any angle required in the work to which the implement is applied.

Figure 1 is a side view of an implement made according to my invention. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a plan view of the same.

A is the stock, made of metal, and, in the main, in the ordinary manner, and provided with the handle B, whereby the requisite reciprocating movement is given to the implement when in use, and also with the upwardly-projecting cheeks m at the sides. At a, is the throat through which project the lower or scraping edges of the plane-iron C, this iron C being confined in the holder D. The holder is composed of two parts, b c, the former of which is pivoted by the lateral bearings at its lower end in close proximity to the throat a, as indicated in dotted outline in Fig. 1, and also shown in Fig. 2. The part c is attached by lugs b’ and pivots c’ to the part b, and carries at its upper end the screw d. By placing the iron C between the two parts and tightening the screw d, the iron is, of course, firmly clamped in place in the said holder. At each lateral edge of the part b of the holder is a lug or ear, g, and arranged in due relation thereto is a bar or support, F, pivoted, as shown at e’, to that end of the stock opposite the handle, and formed at its upper part with a longitudinal slot, a’, of a curvature which, when the supports are in position, as herein presently described, is on an arc more or less concentric with the pivoted point near the throat a of the holder. A transverse bolt, G, having a head, r, at one end and a nut, r’, at the other, is passed through the slots a’ of the supports just mentioned, and also through holes formed in the lugs g of the holder, in such manner that, by tightening the nut r’, the frictional hold of the head and nut of the bolt G upon the supports F will rigidly retain the same in a fixed position, and thereby insure the retention of the holder and its contained scraping-tool at any angle to which it may be adjusted. The degree of adjustment is, of course, limited only by the length of the slots in the supports F, Which latter serve to brace and sustain the tool against the strain exerted when the same is in use. Instead of having the supports pivoted, as hereinbefore described, the same may be constituted in one with the cheeks m — the latter being extended upvvard to a sufficient height, and provided With arc-shaped slots answering to those of the pivoted supports F, and for the same purpose.

What I claim as my invention is —

The combination, With the holder D having lugs g, of the slotted supports F pivoted to the stock A and the tightening-bolt G, the whole arranged and operating substantially as and for the purpose herein set forth.

To all whom it may concern:

Be it known that I, RICHARD W. TANNER, of the city and county of Albany, State of New York, have invented a new and useful Tool for Cabinet-Makers, and other workers of veneer; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which —

Figure 1 represents a perspective view of the invention.
Figure 2 is a vertical view of the same.
Figure 3 is a longitudinal section, through red line, in fig.2.
Figure 4 is a cross-section.
Figure 5 is a view of a modification of the form of the face-block.
Figures 6 and 7 are modifications, shown by end sections, of the said face-block.
Figure 8 represents the face-block with a plane-iron suited to this tool.

The nature of my invention consists in a tool-holder and a face-block properly secured together, and so arranged as to receive and hold a scraper or tooth-plane iron, or a straight plane-iron, or any other similar edge tool, by which the workmen plane, tooth, or scrape even the surface of the veneer.

There are many kinds of woods difficult to even on account of the waving or curling nature of the grain of the fibre. By this tool, any and all kinds of wood veneer may be evened and smoothed, with less labor and trouble, than with the hand-held tools now used.

The tool-holder may he constructed of wood or metal, and consists of a bar about a foot long, fur-
nished with a handle on each end, and is furnished with a holding-bar, pivoted to two eye-bolts, furnished with screws and set-nuts, also with a set-bolt, all of which are arranged and connected with the handled har, so as to fix and hold the scraper, plane-iron, or other similar tool, in any required position.

The face-block is secured to the said tool-holder by proper bolts or screws, and is provided with a mouth to permit the passage of the shavings from the wood, as it is being cut from off its surface.

To enable others skilled in the art to make and use my invention, I will proceed to describe it in reference to the drawings, and the letters of reference marked thereon, the same letters indicating similar parts.

One part of my invention consists in the tool-holder, constructed of the double-handled bar A, figs. 1, 2, and 3, and the tool-bar a, pivoted at each end, as shown in fig. 4, to the two eye-bolts e e, figs. 1 and 2.

The said eye-bolts e e pass through the handle-bar A, from the front to the rear, and are provided with thumb-nuts, by which the said tool-bar may be drawn nearer to the handled bar or further from it.

A screw-bolt, c, also works irorn the back ofthe handled bar A, and into it, and through to the tool-bar a, as shown in figs. 1, 2, and 3.

The scraper S, figs. 1 and 2, or plane-iron S’, fig. 8, is placed against the back of the tool-bar a, fig. 3, and between the handled bar A and the said tool-bar, and when thus placed, the said tool S or S’ is secured in its place, at any angle desired, by means of the said set-bolt c and eye-bolts e e.

The other part of my invention consists in the face-block B, shown in iigs. 1, 2. and 3.

The said face-block may be made of wood or metal, and is furnished with a mouth, b, the same as a plane, and may be either straight on its lower face, as in fig. 3, or concave, as in fig. 5, or the reverse, to fit the surface the tool is intended to operate upon, or they may be made either straight, or concave, or convex, longitudinally, as referred to, with moulding forms similar to those shown in figs. 6 and 7, or any other form, as may be required.

The said face-block is secured to the double-handled bar A., figs. 1, 2, and 3, by means of the screws o o, or their equivalents.

A plain flat face-block may be used, as shown in figs. 1 and 3, to which supplementary blocks B’ may be secured, as shown in figs. 5, 6, and 7, and when thus furnished in sets, together with the straps or plane-irons to correspond, the workman will have a tool which will enable him to perform and finish his work with greater ease and facility than can be done with the means they now have.

When a plane-iron, S’, is to be used, as in fig. 8, I would prefer to have the cutting-edge curved forward, as shown.

Having described my invention, What I claim, and desire to secure by Letters Pat~
ent, is —

The tool~holder, consisting of the block B, double-handled bar A, tool-bar a, eye-bolts e e, with their thumb-nuts, and the screw-bolt c, all arranged and constructed to operate as described, substantially as and for the purpose specified.

The Schedule referred to in these Letters Patent and making part of the same.

_________________

To all whom it may concern:

Be it known that I, WILLIAM DUTTON, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Irnprovernent in Combined Planer and Scraper; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a new and useful improvement in tools used for scraping and planing boxes or barrels, and for removing the marks therefrom; and the invention consists in attaching to a single stock or handle an adjustable scraper, and an adjustable “planing-iron,” as will be hereinafter more fully described.

Figure 1 represents a top view of the tool.
Figure 2 is a longitudinal side view, (in section through the line x x,) so as to show the position and method of fastening and adjusting the scraper and planer-“bits.”

Similar letters of reference indicate corresponding parts.

A is a metallic stock, or shell, so formed that a planing-iron, or bit, is confined to it at about the same angle it would occupy in a joiner’s plane.
B represents the iron, or “bit,” of the plane.
C is the scraper.
D is the shank, to which a handle, of wood or other material, may be attached, or the shank may be extended, so as to form a handle itself.
E is the handle.

Both of the bits, B and C, have slot-holes, so that they can be adjusted or set, for properly operating on the wood.

They are fastened by the thumb-screw F and the screw-lever G, as seen in the drawing.

The manner of operating with the tool will be readily understood from the drawing.
I claim as new, and desire to secure by Letters Patent —

The stock A, adapted to receive the adjustable bits B C, all the parts being constructed and arranged as described, for the purpose specified.

IMPROVEMENT IN CABINET-MAKERS’ SCRAPERS.

Specification forming part of Letters Patent No. 56,651, dated July 24, 1866.

_________________

To all whom it may concern:

Be it known that we, FRANK A. WLLLIAMS, JOHN H. WILLIAMS, and DANIEL G. WILLIAMS, all of Cincinnati, Hamilton county, Ohio, have invented a new and useful Cabinet-Maker’s Scraper; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

The scraper in customary use by cabinet-makers, coach-makers, and other finishers of wood-work consists, as is well known, of a simple blade of steel having a turned or upset and sharpened edge. This blade, being grasped by the workman between the fingers and thumbs of both hands is operated by being thrust forcibly over the work. This operation, besides blistering the hands of the operator, so quickly heats up the tool as to soon oblige him to lay it down. These inconveniences we wholly avoid by mounting the scraper proper in a suitably-formed handle of wood or other non-conducting material. We also, in addition to said provision, apply mechanical devices whereby the tool can be made to scrape with greater or less fineness independently of the degree of force or pressure exerted.

Figure 1 is a perspective view of a scraper embodying our invention. Fig. 2 is a transverse section taken at mid-length of the instrument. Fig. 3 shows the parts of the scraper detached. Fig. 4 represents forms of bits adapted for operation on hollow and on round work respectively.

A represents the bit or scraper proper. B is a stock or handle of wood, suitably excavated to receive the bit and a mouth-piece, C.

The bit A, being sprung into the notches b b’, is adjusted toward the mouth-piece, so as to shave with any desired degree of fineness, by means of a set-screw, D.

Thumb-screws E E’ serve to secure the mouth-piece C, and, through it, the bit A.

On slackening of the mouth-piece C by retraction of the screws E E’ the bit is so far released as to be readily shifted, so as to cut rank or fine. When adjusted to cut fine, it should also, by means of the screw D, be set proportionally near to the mouth-piece. On the retraction of the screw D, the spring of the bit itself draws it automatically away from the mouth-piece. The mouth-piece has a throat or excavation, c, through which the shavings escape.

During operation the heads of the thumb-screws E E’ serve as a brace or abutment fbr the thumbs of the operator.

We have selected for illustration a scraper adapted for flat work; but the device is equally applicable for curved work, the bit and handle being modified in each case as judgment or fancy may indicate.

We claim herein as new and of our invention —

A scraper consisting of the blade A, stock B b, mouth-piece C, set-screw D, and clamping-screws E E’, all constructed and arranged substantially as and for the purpose herein specified.

In testimony of which invention we hereunto set our hands.

PLANE-SCRAPER.

Specification of Letters Patent No. 13,381, dated August 7, 1855.

_________________

To all whom it may concern:

Be it known that I, LEONARD BAILEY, of Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improved Plane-Scraper; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of such drawings, Figure 1, is a side elevation, while Fig. 2, denotes a central vertical and longitudinal section of my improved tool or invention.

In such drawings, A, represents a plane stock or bed which may be constructed of metal and have a handle, B, extended from and above it. The bed is provided with a throat or opening, C, for the scraper or plane cutter D, to pass through, and over this throat and hinged or jointed to the stock (as seen at, x, Fig. 1) so that it may be turned in a direction, either toward or away from the handle, B, is a plate, E, embraced by a screw stirrup or clamp, F, having some equivalent contrivance for fastening the scraper to it.

A forked arm G, is jointed to the upper part of the rear side of the plate, E, and is provided with a female screw, a, for the reception of a male adjusting screw, b, which should be so applied to the top of handle, B, as to be immovable with respect thereto except being rotated in a transverse direction.

For this purpose the rod is provided with a journal, d, extending through a projection, I, having rollers, e, f, arranged on opposite sides of the said projection as seen in the drawings.

The movable plate and its screw clamp may be termed the holder of the scraper or plane iron. By means of the adjusting screw the inclination of the scraper to the lower surface of the bed or stock may be adjusted as occasion may require it often being desirable to accomplish this result in order to prepare the tool for a correct performance of its duty — the same depending on the particular kind or character of the wood on which we may wish to employ it — the specific object of such tool being to scrape or pare down the surface of such wood.

As the turning points of the cutter holder, are arranged a short distance above the bottom surface of the stock (as seen at, x, in Fig. 1) it will be observed that any movement of the holder on such points, will either elevate or depress the lower edge of the cutter scraper. Thus by means of the adjusting screws or mechanism, the fineness of the cut of the scraper may be modified.

The utility and advantage of a scraper or smoothing plane constructed in the above described improved form must be evident to a skilful workman on inspection of it.

I claim —

Combining the scraper or plane cutter with the stock by means of the movable holder and its adjusting mechanism substantially as specified.

In testimony whereof, I have hereunto set my signature this eleventh day of July A. D. 1855.

LEONARD BAILEY.
