Specification forming part of Letters Patent No. 221,763, dated November 18, 1879; application filed September 15, 1879.

_________________

To all whom it may concern:

Be it known that I, JOHN W. AMMONS, of Columbia, in the county of Boone and State of Missouri, have invented a new and Improved Grooving-Iron, of which the following is a specification.

My invention relates to improvements in the tongued irons or bits used in grooving-planes.

Heretofore the form of these irons has been such as to leave the corners of the groove sharp. This is objectionable on account of their liability to break off when the tongue is forced in and carried back into the groove, whence they have to be removed at a great expense of time and trouble; or if allowed to remain they interfere with the making of a good joint. To prevent this with the present tools, it is the habit of many workmen to chamfer off the corners with an ordinary rabbeting-plane; but this requires the use of another tool and the expenditure of valuable time.

The object of my invention is to provide a plane-iron which will chamfer off the outer corners of the groove simultaneously with the planing of the groove.

The invention consists in a plate with beveled cutting-edges, a slot, and a longitudinal groove, in combination with a grooving-iron provided with a cutting-edge, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of my improved iron. Fig. 2 is a plan view of the same. Fig. 3 is a cross-section on line x x of Fig. 2; and Fig. 4 represents, in perspective, a modified construction of the iron.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the grooving bit or iron, made of a rectangular bar of steel, with cutting-edge B. On the upper side of iron A is placed a flat plate of steel, C, which is secured to the bit by a set-screw, b, passed down through the slot c in the plate into a threaded hole in the bit.

In the under side of the plate is a shallow longitudinal groove, d, sufliciently wide to receive the bit, as shown in Fig. 3. This groove d, together with the set-screw b, connects the plate C rigidly with the bit A, so that the plate C can neither rise nor lose its parallel adjustment with relation to the bit.

At the lower end of plate C the corners are chamfered or beveled off at any suitable angle, and the corners are given sharp cutting-edges e e.

The plate C is designed to extend one-sixteenth of an inch beyond the sides of the bit, so that the angular cutting-edges e e will come in contact with the sides of the groove cut by the bit. The object of this arrangement is to chamfer off the upper corners of the sides of the grooves at the same time the groove is planed, so as to enable the flooring-tongue to be entered into the groove without trouble, and without liability of breaking off the corners of the groove and forcing the splinters in the groove, as before mentioned.

The lower end of plate C forms the shoulders of the plane-iron to limit the depth of the groove.

In Fig. 4 is shown a bit with the shoulders forming a part thereof, in the usual manner. Herein the front lower edges, f f, are cut off at an angle and sharpened to an edge, the same as the edges e e of the plate C.

Both forms of plane-irons operate in the same way to chamfer off the corners of the sides of the groove; but the arrangement first described offers superior facilities for keeping the bit in good order, on account of the ease with which the edges e e can be sharpened.

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

The plate C, having beveled cutting-edges e e at a suitable angle, and provided with a longitudinal groove, d, and slot c, and set-screw b, in combination with the grooving-iron having cutting-edge B, for the purpose of chamfering off the corners of the sides of the grooves, substantially as described.

IMPROVEMENT IN BENCH-PLANES.

Specification forming part of Letters Patent No. 219,186, dated September 2, 1879; application filed June 9, 1879.

_________________

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bench-Planes, of which the following is a specification.

In the accompanying drawings, Figure 1 is a central longitudinal section of a bench-plane which embodies my invention. Fig. 2 is a transverse section of the same, taken on a plane parallel with the plane-iron and just under it; and Fig. 3 is a side elevation of a detached part thereof.

The invention is principally designed for a cheap plane with a wooden stock.

The first part of the invention relates to the manner of and devices for securing the cap A, which holds the plane-iron in place. B designates the stock, made of wood, and throated or mortised out for the plane-iron, like ordinary plane-stocks. C designates a frame composed of a slotted plate, a, and two arms, b b, with rounded ends. This plate extends laterally, so as to span the front of the mortise in the stock, and its arms extend backward by the sides thereof. This frame C is secured to the stock by means of a screw extending through the slot in the plate of said frame.

Notches are formed in the upper side of the cap A, near the edges, as shown in Fig. 1, which receive the ends of the arms b b, said arms, when the frame is secured, forming bearings for the cap to swing on, and to hold it against the plane-irons D when the screw c is tightened.

A cap swinging on bearings and provided with tightening-screw is not new with me, but the peculiar construction of these bearings enables me to dispense with a long iron frame upon the top of the stock, usually employed in wooden planes having such a cap, and, furthermore, the mortise in different stocks will vary somewhat, so that it is oftentimes desirable to secure the plate farther up or down upon the inclined side of the mortise, to bring the ends of the arms b b at the proper distance from the plane-iron. The slot in the plate of the frame enables this adjustment to be made, after which the screw is tightened to secure the frame in place.

The adjusting device which I employ in this style of plane is in the nature of an improvement upon the compound-lever adjustment patented to Henry Richards and myself in Re-issue No. 7,565, dated March 20, 1877 . A narrow mortise is made in the stock under the plane-iron D, in the middle of its width, and upon the bottom of said mortise I secure the base E of the adjusting device to the stock. This base has two standards or projections, d e, in the former of which is the fulcrum for the main lever F, and in the latter is one fulcrum of the angle-lever G. This angle-lever, as its name implies, has two arms, the outer end of one of which arms is pivoted to the standard e, and the outer end of the other arm is pivoted to the lever F, between its fulcrum and its free or handle end. This lever G is slotted longitudinally, so that the main lever passes through and works in said slot, the two opposite sides of the angle-lever being connected by a bridge or pad, f, as shown. The upper side of this pad is provided with fine transverse serrations, and the under side of the plane-iron is serrated in like manner. The top of the pad is slightly rounded. The position of the adjusting device upon the stock should be such that the serrated pad is nearly under or opposite the end of the tightening-screw c. In fact, one of the advantages of this construction of the compound lever is that the connection with the plane-iron may be directly opposite the tightening-screw., so that fine serrations may be employed without any danger of disengagement by the springing of the plane-iron, because the tightening-screw will not allow the iron to spring at that point.

The plane-iron is set in position with its end somewhere near the bottom face of the stock, and then its upper end is allowed to engage the serrated surface of the bridge on the angle-lever. The cap-plate is then placed and secured in position, as shown in Fig. 1. Pressing down upon the outer end of the main lever F will depress the arm of the angle-lever, which is pivoted to said main lever, causing the angle-lever to turn on its fulcrum in the standard e, when the bridge will be carried forward, and the plane-iron with it, to project its cutting-edge more or less, as may be desired. The reverse movement of the lever draws the plane-iron backward.

I am aware that the plane-iron and various adjusting devices having coarse notches or serrations taking into each other at various points not opposite the tightening-screw have heretofore been used, and I hereby disclaim the same.

I claim —

1. In a bench-plane, the frame C, composed of slotted plate a and arms b b, in combination with an ordinary wooden plane-stock and holding-cap, substantially as described, and for the purpose specified.

2. In a bench-plane, the combination of the holding-cap having tightening-screw at its upper end, the plane-iron with fine serrations upon the underside, and an adjusting mechanism having a finely-serrated pad for engaging those in the iron, and with said pad located opposite the proper position for the tightening-screw, substantially as described, and for the purpose specified.

3. In a bench-plane, the combination of the base-plate E, the main lever F, pivoted thereto, and the angle-lever G, having one of its arms pivoted to said base-plate and the other arm pivoted to the main lever, and also provided with a device for connecting it with the plane-iron, substantially as described, and for the purpose specified.

Specification forming part of Letters Patent No. 216,698, dated June 17, 1879; application filed April 28, 1879.

_________________

To all whom it may concern:

Be it known that I, HENRY B. PRICE, of the city of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Planes, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

The invention relates, first, to the adjustment of the angle or pitch of the cutter according to the quality of the wood to be planed; and, second, to the adjustment of the mouth of the plane; and is applicable to all kinds of planes, but especially to bench-planes composed either entirely of metal or of metal and wood combined.

Heretofore the pitch of the cutter of every plane has been fixed and unchangeable, and carpenters and joiners have been compelled to keep on hand at least two kinds of planes — one in which the cutter is at common pitch, or forty-five degrees from the horizontal line, used for soft woods, and another for hard wood, in which the cutter is either at York pitch, middle pitch, or half-pitch, corresponding, respectively, to fifty, fifty-five, and sixty degrees from the horizontal line.

The object of my invention is to provide a device by which the angle or pitch of the cutter may be altered at pleasure, so that the same plane may be used for both soft and hard wood, and by which device the mouth of the plane can also be regulated.

This object I attain as follows, reference being had to the accompanying drawings, in which —

Figure 1 represents a sectional view of the invention as applied to an ordinary metallic plane.

The wedge D, of which a sectional view is given in Fig. 2, is divided off along its inclined plane on both sides into corresponding ratchets d d d d. Half-way through the center of this wedge runs a slot, f, marked on its edges with the notches e e e e, as shown in Fig. 2.

Through the slot f passes a tap-bolt or thumb-screw, s, which screws into the sole or seat of the plane, and when screwed down holds the wedge D fast to the sole of the plane.

The tap-bolt s is provided with a gage or clamp, h, (shown in Fig. 3,) which passes over the edges of the slot f and aids in holding the wedge D in position.

When the tap-bolt s is loosened the wedge D can be slid back and forth along the slot f.

The bed-plate C, upon which the cutter B rests, is held fast by the tap-bolts i, and in the ordinary metallic plane rests directly with its heel g on the sole of the plane.

To meet the object of my invention the heel g is shortened and works in the ratchets d d d d.

The operation of the device is as follows: To obtain a higher pitch, remove the clip A and the cutter B, loosen the tap-bolts i and s, slide the wedge D forward until the heel g works into a ratchet, which shall give the required incline or angle to the bed-plate C; then fasten the tap-bolts i and s, replace the cutter B and the clip A, and the object will be attained.

To lower the pitch, go through the same process, except that the wedge D is pushed backward instead of forward.

By means of the notches e e e e e along the edges of the slot f as shown in Fig. 2, the operator, while regulating the pitch of the cutter, can at the same time adjust the mouth of the plane, so as to obtain either a “close” or a “coarse” mouth as may be desired.

By fastening the clamp or gage h (see Fig. 3) just over a notch, e, a close mouth will be obtained when the cutter is raised to the corresponding ratchet d. Thus, if the cutter is raised to a pitch represented by the fourth ratchet, then by fastening the gage h just over the fourth notch a close mouth will be obtained. A coarse mouth is procured by fastening the gage h, between any two notches — thus in the case given between the third and the fourth; that is, by moving the gage toward the third notch, but not beyond the middle point between the two, a coarse month is obtained.

The wedge D may be made of metal, wood, or any other hard substance; and in place of the tap-bolt s a thumb-screw or spring-fastening can be substituted.

What I claim as my invention is —

l. The adjustable slotted wedge D, divided along its inclined plane on both sides into corresponding ratchets, and marked with graduated notches or marks along the edges of its slot, substantially as described.

2. The combination of a wedge divided along its inclined plane on both sides into corresponding ratchets, and provided with a notched slot running half-way through its center, with a tap-bolt or screw, which passes through the slot and fastens into the sole of a plane, and which, when loosened, allows the wedge to slide back and forth along the slot, but when fastened holds the wedge firmly in position, whereby the bed of the cutter of the plane is raised or lowered and the pitch of the cutter is changed accordingly, and by which the mouth of the plane is also regulated, substantially as described.

3. In combination with the wedge D, the tap-bolt or thunmb-screws and the gage h, Substantially as described.

IMPROVEMENT IN FLEXIBLE-FACED PLANE-STOCKS.

_________________

Specification forming part of Letters Patent No. 216,577, dated June 17, 1879; application filed April 16, 1879.

_________________

To all whom it may concern:

Be it known that I, SAMUEL D. SARGENT, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Flexible Faced Plane-Stocks, of which the following is a specification.

My invention consists of the combination, in a flexible-faced plane-stock, of the body of the stock, having a transverse recess adjacent to the throat, with an independent throat-piece fitted to said recess and having the flexible face attached, as hereinafter described; also, in the throat-piece, of malleable metal, independent or otherwise, and provided with a series of lugs rigidly formed in one and the same piece with the throat-piece, in combination with the flexible face-plate having a series of holes through which said lugs pass, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of a flexible-faced plane-stock which embodies my invention. Fig. 2 is alongitudinal section of the same through one side of the stock. Fig. 3 is a detached portion of the flexible-faced plate and attached throat-piece of the same. Fig. 4 is a detached under-side view of said throat-piece, and Fig. 5 is an enlarged sectional view on line x x of Fig. 3.

The flexible-faced stock, the mechanism for adjusting said face-plate, and the mechanism for adjusting the plane-iron are, with the exception of the parts hereinafter described, substantially the same as shown in the two patents to H. M. Clark, September 25, 1877; but they may be of any other style or kind.

The body of the stock A, I make of iron and with a dovetailed groove transversely across the bottom at the point where the throat a is designed to be located.

A dovetailed throat-piece, B, is fitted snugly into said groove, as shown in Figs. 1 and 2. This throat-piece has the ordinary throat a formed in it, through which throat the cutting-bit or plane-iron extends.

The flexible face-plate C is firmly secured to said throat-piece before it is inserted in the stock.

Heretofore, so far as I know, the flexible face-plates of circular plane-stocks have been secured directly and permanently to the stock, and generally by screws the heads of which were ground or polished off so as to take out the slot therein. A face-plate so secured could not be removed for repairs by an ordinary carpenter, and in any event could only be removed with more or less difficulty.

I intend to have the stocks and throat-pieces made by machinery and all alike, so that in case it is desired to remove the flexible face-plate and replace it with a new one it is only necessary to disconnect the ends of the face-plate and drive out the throat-piece.

A new face-plate can be ordered from the factory and inserted in its place, all of which can be done by any ordinary carpenter or mechanic, and without returning the plane-stock to the factory.

Thus it will be seen that the throat-piece and its attached face-plate are both attachable and detachable from the stock, whereby I call the throat-piece an independent one.

So far as the above feature of my invention goes the face-plate may be secured to the independent throat-piece by screws, rivets, or in other ordinary manner; but I prefer the method hereinafter described, and which constitutes the second feature of my invention.

I make the throat-piece of some kind of malleable metal, (good malleable iron will answer,)
and with a series of lugs, b, upon its under side. A mill is then run over the surface of the throat-piece both lengthwise and crosswise, to mill the entire surface, except that occupied by the lugs, leaving them square, as shown in Fig. 4.

A series of holes of corresponding shape and location are punched in the face-plate, which holes are conntersunk on the face side of the plate by a proper revolving tool. The lugs of the throat-piece are then driven into the holes in the plate, their ends upset or riveted, and then polished off, when the plate is ready for use.

The under face of the throat-piece outside of the lugs may be slightly rounded, and said piece may be made so thick that the face-plate will project slightly below the other parts of the stock, so that a good convex curve may be given to the face of said plate.

A few of the advantages of the solid lugs on the throat-piece are as follows, viz: Being short and solid, there is only the thickness of the plate for them to stretch, give, or work in, whereby they form a much firmer fastening than screws or rivets, which are necessarily longer, and the lugs may be set nearer to the throat a, especially with reference to the beveled side of the throat, thereby allowing the greatest possible freedom in bending the face-plate of the stock, while at the same time it is secured firmly.

I have herein described this second feature of my invention as embodied in an independent throat-piece; but if desired the same rigid lugs might be formed contiguous to the throat in the stock, the stock and throat-piece being made of a single piece of malleable iron, in which case the throat-piece would not be an independent one, but all the advantage of a firm fastening, by reason of short lugs and of fastening the face-plate near the edge of the throat, would be embodied in such a stock.

I claim as my invention —

1. In a flexible-faced plane-stock, the body of the stock, having a transverse recess adjacent to the throat, in combination with an independent throat-piece itted to said recess and having the flexible face attached, substantially as described, and for the purpose specified.

2. In a flexible-faced plane-stock, the throat-piece, of malleable metal, independent or otherwise, and provided with a series of lugs rigidly formed in one and the same piece with the throat-piece, in combination with the flexible face-plate having a series of holes through which said lugs pass, substantially as described, and fbr the purpose specified.

_________________

To all whom it may concern:

Be it known that I, CHARLES SPRING, of Hyde Park, county of Norfolk, State of Massachusetts, have invented an Improvement in Spoke-Shaves, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to an improved drawing-knife or shave, it consisting, essentially, of a blade having one or both of its ends shaped to bear at one side of the blade against a seat made upon a handle, and to cooperate with shoulders or projections upon the handle, both when the handle extends from the blade at substantially a right angle from its cutting-edge, as shown in full lines in the accompanying drawings, and also when the handle extends in the direction of the length of the blade, as shown in dotted lines, the said handle and blade in each of its two positions being locked and held by a locking device.

Figure 1 represents, in side elevation, a drawing-knife, constructed in accordance with this invention; Fig. 2, a top view thereof, the left-hand handle being turned to project in the direction of the length of the blade; and Fig. 3, a detail of the upper end of the handle.

The blade a, as herein shown, has its ends b b flattened at its rear side to bear against a flattened portion, c, of the handle d, while the edges 2 3 of the blade, as shown in Fig. 1, are made straight, to bear the edge 2 against the lugs f f, as shown in Fig. 1, when the handle extends from the blade, as represented in full lines, or from the blade in the direction of its width.

The handles herein shown are supposed to be of metal ; but their lower portions, or the parts grasped by the hand, may be of wood, if preferred, and screws g, projecting from the upper ends of the handle at right angles to their length, are extended through holes in the blade, and a nut, h, is then applied to each screw, to securely clamp each end of the blade to each handle.

By employing two lugs, f f, instead of one long rib or shoulder, extended from one to the other side of the handle, a space, 4, is left between the lugs, into which (the nut li being loosened, so as to permit the blade and handle to be somewhat separated) when the handle is turned to occupy the position shown in dotted lines, Fig. 1, or in full lines at the left of Fig. 2, the end of the blade may enter, its edges 2 3 falling into the space 4 between the lugs f f which, as the nut is again turned to press the rear side of the blade against the seat portion c, at the upper end of the handle, causes the lugs f f to act with the screw and nut, and grasp and hold the handle and blade, so that the handle will project therefrom substantially in the direction of its length.

One or both of the handles may be held, as in full or dotted lines, Fig. 1, according to the particular work being done with the knife, or whether the workman is right or left handed.

A drawing- knife with the handle as in dotted lines may easily be used to hew or chip a piece of wood.

It is herein assumed that the handle of a drawing-knife has been fitted to a rounded end of a blade, so as to turn thereon, and project from the blade at right angles to its edge or face or back, the handle in such plan turning on an axis parallel with the length of the blade rather than at right angles thereon, as herein provided for.

It is obvious the screw might be attached to the blade, and be made to project through an opening in the handle; but this plan is not liked as well as its converse. (Shown in Fig. 1.)

The handles, constructed as shown, may be turned just opposite the full-line position of Fig. 1, and then the blade may be pushed with its cutting-edge as in advance.

I denominate the screw and nut as “holding devices.”

I claim —

As an improved article of manufacture, a drawing-knife composed of a blade and a movable handle, provided with a scat portion, c, and bearings or lugs f f, to confine the flattened ends of the blade when the handle projects from the blade in the direction of its width or in the direction of its length, substantially as described.

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

Specification forming part of Letters Patent No. 213,104, dated March 11, 1879; application filed January 17, 1878.

_________________

To all whom it may concern:

Be it known that I, EDWARD F. GORDON, of Concord, in the county of Merrimack and State of New Hampshire, have invented a new and Improved Lubricator, of which the following is a specification:

Figure 1 is a side elevation, partly in section, of a plane having my improved lubricating device attached. Fig. 2 is a face view of the same. Fig. 3 is a plan view of a portion of a planer-bed containing my improvement. Fig. 4 is a transverse section taken on line x x in Fig. 3.

My invention relates to lubricators for hand-planes and the beds of planers, molding and scraping machines, or for other metallic surfaces requiring lubrication.

The invention consists in holes or cavities formed in the surface to be lubricated, said cavities being filled with wood or other unyielding porous material saturated with oil. The cavities are either wholly filled with wood or partly filled, so as to leave a chamber for containing oil.

This improvement is especially designed for lubricating metallic surfaces that are moved over wood surfaces, or over which wood surfaces are moved, in the processes of wood-working.

Referring to the drawings, A is an ordinary iron hand smoothing-plane, in the face of which a recess or cavity, b, is formed, into which is driven a piece of wood or other suitable porous material, c, which partly fills it, leaving the chamber c’ for containing oil. The grain of the wood runs at right angles to the face of the plane, so that the capillary tubes of the wood may draw from the oil-chamber a suflicient quantity of oil to constantly lubricate the face of the plane or the surface upon which the plane is moved, thereby obviating the sticking and friction which are common to metallic planes. The upper wall of the oil-chamber is apertured and provided with a screw-plug, d, for the purpose of filling.

In Figs. 3 and 4, B represents a portion of the bed or presser-bar of a planing, sticking, or scraping machine, in which there is an oil-chamber, C. In the upper surface of the bed there are slots e, that communicate with the oil-chamber C. In these slots pieces of wood f are driven, so that the grain is at right angles to the face of the bed, and their upper ends are even with the face of the bed, while their lower ends extend downward and dip into the oil contained by the chamber C. The oil-chamber is provided with a filling-aperture, g, which is closed by a screw-plug, h.

In some cases the oil-saturated wooden plugs or pieces may entirely fill the cavities in the surface to which the lubricator is applied, as the wood will contain a sufficient quantity of oil to lubricate the surface for a considerable time.

I do not limit or confine my improvement to any particular form or proportions, nor to its application to any special tool or machine, as it may he made in various forms, and is applicable to tools and machines of every sort in which wood is moved in contact with a metallic surface, or the metallic surface is moved in contact with the wood, in the processes of wood-working. It may also be applied with advantage to metal-working machines and to metal surfaces working in contact.

I am aware that it is not new to fill recesses in the faces of planers with wood or soap-stone and without any lubricant; also, that it is not new to use a reservoir filled with oil that is fed by a wick or leather conductor; but the latter soon exhausts the oil and soils the stock that is being worked. Mine, on the contrary, always presents a hard, smooth surface, and feeds just a sufficient trace of oil to lubricate without soiling the stock; hence,

What I claim is —

The combination, in wood-working machinery, of the oil-reservoir b and the wooden plug c, the latter having its grain at right angles to the working-face of the planer, scraper, or molder, as shown and described.

Specification forming part of Letters Patent No. 212,986, dated March 4, 1879; application filed December 9, 1878.

_________________

To all whom it may concern:

Be it known that I, LOUIS C. RODIER, of Westfield, county of Hampden and State of Massachusetts, have invented new and useful Improvements in Bench-Planes, which improvements are fully set forth in the annexed specification and in the accompanying drawings.

My improvements relate to metallic bench-planes; and my invention consists in an improved knife-carriage, pivoted between the side walls of the stock, improved devices for operating the knife-carriage and knife to govern the depth of the cut, an improved construction and arrangement of parts whereby the operator can, without removing the plane from the board, and by the use of the fingers of the hand grasping the rear handle of plane, reduce the thickness of the shaving from that of a jack-plane to that of a smoothing-plane.

Referring to the drawings, which consist of two sheets and eight figures, Figure 1 is a longitudinal section of my plane. Fig. 2 is a perspective view of the knife-carriage and its operating-cam, showing its relative position to the hand of the operator while grasping the rear handle of the plane. Fig. 3 is a plan view of the knife-clamp and its set-screw. Fig. 4 is a view of the cam which actuates the knife-carriage, and the rear arm of the latter. Fig. 5 is a transverse section through the stock on the line x x, Fig. 1, showing the latter and the rear end of the carriage. Fig. 6 is a plan view of that portion of the stock embracing the throat thereof, with the carriage and trunnion-bar. Fig. 7 is a plan view of the face of the stock. Fig. 8 is a view partly of a side elevation and partly in section, showing a modified construction of the knife-rest.

Like letters of reference refer to like parts in the different figures.

A is the stock. B is the knife-carriage. c is a carriage-spring. d is the trunnion-bar. b is a cam-shaft support. e is a spoked cam-shaft wheel. i is the cam-shaft. o is the cam. h is a knife-brace on carriage B. n n’ are hooked arms on carriage B. D is the knife-clamp. s is the knife-clamp screw. t t are ears on the knife-clamp. m is the throat of the plane. a’ is the rear end of carriage B, under I cam o. z is a screw in trunnion-bar, d. K is the knife. H, Fig. 8, is a knife-rest just back of throat m.

I cast my plane-stock and fit to it the usual handle and front knob. Just forward of the handle I cast a cam-shaft support, b, into which I fit a cam-shaft, i, and secure to its rear upper end a wheel, e, and to its lower end cam o. Through the sides of stock A, opposite each other, I drill two holes for the reception of trunnion-shaft d. Carriage B is made to it between the sides of stock A, back of throat m, as shown, and is drilled so that it may be mounted on trunnion-bar d in its place in stock A, and is provided with a vertical knife-brace, h, and a rearwardly-projecting arm, a’, under cam o, and its sides rise up and turning backward form hook-shaped arms n n’.

Trunnion-shaft d has its ends and its center turned of about equal diameters; but between its center and the sides of the carriage B its diameter is reduced, so that its diameter centrally between said sides is the greatest. Thus fitted and arranged, carriage B and trunnion-bar d are placed in stock A, and said carriage has a vibratory motion therein, pivoted on said bar d.

In Fig. 5 it will be seen that the interior of stock A is made with its bottom the highest in the middle at the place there shown. The rear end of carriage B reaches over said highest part, and lying under said carriage, its sides resting on the ends thereof, is a spring, c, having a bearing midway between its ends on said highest part of the bottom of stock A, as seen in Fig. 5.

Knife-clamp D is made of the form shown, being of the same width as the distance between the sides of carriage B, provided with projecting ears t t on its edges and a set-screw, s, through its upper end.

When knife K is put into the plane its lower end bearing just above its cutting-edge rests upon the center of trunnion-bar d, with its cutting-end in the throat m of the stock, and just above, it finds a bearing on knife-brace h. Knife-clamp D is now placed on top of knife K, and slid down until its ears t t engage under the hooked arms n n’ on carriage B. In this position set-screw s is turned down against knife K. Ears t t now become a fulcrum on which clamp D bears upwardly, restrained by hooked arms n n’. This throws the lower end of the clamp strongly against the knife near its cutting-edge, clamping its lower end firmly between the end of said clamp and the center of trunnion-bar d, and pressing its part under screw s firmly against brace h, and thus rigidly locking the knife to the carriage.

My improved plane is adjusted and operated as follows: When the knife is put in as above described, the cam o is turned by wheel e, so as to depress arm a’ on carriage B and the rear end of said carriage against spring c, under it, as low as it will go. With the carriage in this position knife K is locked thereon, as just described, with its cutting-edge in throat m just flush with the face of the plane-stock. Knife-clamp D is truly fitted to carriage B, so that its lower edge, when in operating position in carriage B, is at right angles to a longitudinal center-line through the plane. Knife K, it will be seen, has a rear support only on its longitudinal center-line, touching on the center of the elliptic-shaped bar d and on the narrow end of knife-brace h, on carriage B. Thus the knife is forced by operating-screw s against it, to adjust itself to the position of the knife-clamp D, which, being true, as stated, causes the edge of the knife to be truly brought into place in the throat m. Knife K being adjusted, as above stated, the handle of the plane is grasped by the operator, as shown in Fig. 2, and the plane is applied to its work.

It will be seen that the knife guiding cam-wheel is in such convenient form and position relative to the plane-handle that the operator can vary the depth of the cut even from one end of it to the other, and by turning wheel e and cam o to the left the rear end of carriage B rises, forced up by spring c, swinging on trunnion-bar d, and carrying with it in such motion knife K, which, in this position, operates something like a lever whose short arm is below the center of bar d, and whose long arm is represented by that part of it above said bar.

It is easily understood that the elevation of the part of knife K above bar d and the consequent depression of the lower end of the knife increases the depth of the out that the plane will make, and vice versa. It will also be seen that all of the points of resistance which support the knife against the force of the cut are solid and unyielding, and that the devices for governing the cut are so constructed and applied that the operator may commence with a deep heavy cut against the grain of hard tough wood, and while planing gradually elevate the edge of the knife by turning wheel e and cam o to the right until he produces the smooth fine shaving of a smoothing-plane. The cutting-edge of the knife is so backed up close to its end by bar d that the knife cannot chatter under any circumstances.

The devices for securing the knife to the carriage are such that it is not necessary that a specially-constructed knife be used with this plane; and if it be necessary from any cause to use an unusually thin knife, I have provided a means for compensating therefor in the screw z, placed at the bearing-point thereon in bar d, Fig. 6, which, in such an emergency, may be turned out of said bar far enough to cause the edge of such a knife to assume its proper position in throat m.

In case it may be desirable to modify the construction of my plane by omitting to extend bar d quite across the stock from side to side, substituting therefor short trunnion-bearings reaching just through the sides of the stock and of the carriage, I have provided a center-rest, H, Fig. 8, for the knife, cast on the stock about where the center of bar d would come.

For the purpose of tightening and strengthening the sides of the stock, I cast it with vertical grooves therein, as shown in Fig. 8.

In Fig. 7 it will be seen that I cast sinuous grooves in the face of stock A, running longitudinally thereon. The general object of such or straight grooves — viz., to prevent the adhesion of the plane to a very smooth surface — is well understood, and to accomplish that object straight grooves are sufficient; but in using a plane so made it is found that in planing the sharp corner of a board the corner will often drop into one of the grooves, and thus become scraped and injured; but if the face be corrugated with sinuous grooves, as shown, this inconvenience is entirely obviated.

I am aware that it is not new to construct a metallic plane-stock having a knife-carriage pivoted within its sides, and I do not broadly claim a plane so constructed; but

What I claim as my invention is —

1. The plane-stock A, provided with the cam-shaft support b, in combination with cam o, shaft i, wheel e, knife-carriage B, trunnion-bar d, and spring c, constructed and arranged substantially as and for the purpose set forth.

2. The combination, with carriage B, provided with hooked arms n n’ and the knife-brace h, of the elliptically-shaped trunnion-bar d, knife K, and knife-clamp D, provided with screw S, substantially as and for the purpose set forth.

3. In a plane-stock provided with a vibratory knife- carriage, the knife K, arranged to have its rear support on said carriage, substantially on the longitudinal center-line of the knife, with the cutting-end of the knife resting on and supported bythe axial pivot of the carriage.

4. The combination of spring c, carriage B, and cam o, substantially as and for the purpose set forth.

IMPROVEMENT IN PLANES.

Specification forming part of Letters Patent No. 211,852, dated February 4, 1879; application filed November 14, 1878.

_________________

To all whom it may concern:

Be it known that I, ANDREW JOHNSON, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Planes, of which the following is a specification, reference being had to the accompanying drawings, illustrating my improvement.

The present invention relates to an improvement in joiners’ planes; and the nature of the present invention consists in the novel means for combining the plane bit and stock, whereby a non-slotted bit is held in place by compression of a cap, which is brought with proper force on the bit by means of bolts secured to the sides of the stock. The compressing-plate has side eyes, through which the said bolts pass, and turned onto the bolts are thumb-screws, which may be loosened to move the bit to any desired feed, as the whole is to be hereinafter fully described and shown.

In the drawings, Figure 1 is a longitudinal central section of a smoothing-plane provided with my improvement; Fig. 2, a plan or top view of the same. Fig. 3 is a top view of the bit-cap removed from the other parts. Fig. 4 is an inverted view of the compressing-plate; Fig. 5, an elevation of one of the screw-bolts removed from its position in the stock. Fig. 6 is an enlarged broken central longitudinal section, being an enlargement of the middle portion of Fig. 1; Fig. 7, a transverse section of the plane, taken through x x, also enlarged.

A represents the plane-stock, which has the ordinary construction, and B is an ordinary non-slotted bit, which is fitted on the base of the throat of the stock, as in other planes in the state of the art, there being, however, no key-seats for a wedge.

The cap C is provided with a slot, the margins of which are formed to countersink in the ordinary manner the nut F, which is turned on the screw G, or receives it, that the clamping-plate H and cap C may be rigidly united when required. The upper side of the cap, and surrounding the slot D, is provided with a projection, E, which fits into a recess, L, in the plate H, and insures a true movement of the cap to or from the edge of the bit. The cap C is also provided with notches I on its top side and near its upper end, in which may be inserted a screw-driver or other tool to set the cap from the edge of the bit, the cap being set to the edge of the bit by hammer-blows on the head J.

The plate H is provided with pipe-eyes N N on its sides, which are located so as to pass over screw-bolts O. These bolts are inserted in the margins of the throat of the stock, and the holes in the plane through which they are inserted are plugged.

Thumb-nuts P, turned onto the upper end of the screw-bolts, hold the plate H, cap C, and bit B firmly in the stock.

Rubber pipes or rubber strips R, are placed around the screw-bolts O, for the purpose of raising the cap C from the bit when the thumb-nuts P are loosened, that the bit B may be adjusted, the rubber coming high enough on the bolts to accomplish this purpose by pressing against the under ends of the pipe-eyes N.

By this means non-slotted bits can be used with the advantage of a cap without the objection to the slot, which renders the bit useless when it is worn to the slot, and at the same time the bit C can be removed from or inserted in the throat at the face of the plane, and thus obviate the drilling of the bit by its contact with the cap, as when the bit is inserted in the top of the stock.

I also make plane spoke-shaves on this principle, and they have the same advantages as herein related in reference to the plane; and I also attach my device to planes having other forms and lengths, and they also operate in a superior manner.

I claim as new —

1. The combination of the bit B, cap C, compression-plate H, screw-bolts O, thumb-nuts P, and stock A, as and for the purpose set forth.

2. The rubber R, in combination with bolts O, stock A, thumb-nuts P, bit B, cap C, and plate H, provided with eyes N, as and for the purpose described.

Specification forming part of Letters Patent No. 211,516, dated January 21, 1879; application filed September 18, 1878.

To all whom it may concern:

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Bench-Tools,of which the following is a specification:

The nature of my invention relates to certain new and useful improvements in hand or bench tools of the plane class, and is particularly designed for use in sticking a bead or molding upon circle or irregular work.

The invention consists in a double-faced plane-stock, in which are removably secured proper heads, carrying the cutting-blades, all as more fully hereinafter set forth.

Figure 1 is a perspective view of my improved device ready for use. Fig. 2 is a perspective view of one of the cutter-heads removed. Fig. 3 is a bottom plan of the same, and Fig. 4 is a longitudinal section on the line x x in Fig. 2.

In the accompanying drawing, which forms a part of this specification, A represent a metallic stock with the plane-faces d, in which are cut proper openings to receive the heads and cutters, hereinafter described. B represent cutter-heads provided with throats. Upon these heads B are removably secured the blades C, which are held in position by means of the plates D and screws b, or in any other suitable manner. Adjustably secured to one side of the heads B are spur-blades E, which cut the straight side of the channel in a beading.

Extending downward from the faces of the heads B are two ribs, F G, the latter of which is oval in longitudinal section, while the inner face of the former has a contour corresponding to the cutting-edge of the blade C, which passes through it, and which produces the molding desired. The faces of these ribs are formed in the segment of a given circle. When the heads are placed in the stock, they are held in position by buttons H, or other suitable means.

In practice, when it is desired to cut a bead or molding upon the inner edge of an arch or circle, the device is placed to its work, so as to cut with the grain, the rib G following the line of the edge of the board, while the blade C and spur-blade E cut the inner half of the bead and channel. To cut the remaining half of the bead, the device is reversed or turned over, and the other head used, as the nature of the work may require, so that the cut will always be with the grain.

While the ribs F G are formed in the segment of a given circle, the device is by no means limited to work in such circle, but can be used in work the radii of which is greater or upon straight work.

The heads carrying the cutting-blades may be constructed to out different sizes, and be interchangable, using but one stock for a set of heads.

What I claim as my invention is —

1. The double-faced triangular stock A, having the cutter-heads B on opposite sides, and the cutters C E, adjustably secured in such heads, substantially as and for the purposes set forth.

2. A bench-tool for cutting circular or irregular moldings, consisting of a double-faced triangular stock, A, cutter-heads B on opposite sides of said stock interchangeably held therein, cutters C E adjustably secured in such cutter-heads, guide-ribs E G, and button H, for holding the cutter-heads in position, all substantially as described and shown.

_________________

To all whom it may concern:

Be it known that I, JAMES H. LEWIS, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Bench-Tools, of which the following is a specification:

The nature of my invention relates to certain new and useful improvements in hand or bench tools of the spokeshave class for working curved moldings, having for its object to so construct the same as to enable the operator to work with the grain of the timber when it reverses in direction, thus avoiding the expense of a second tool of the same configuration.

The invention consists in providing the segment stock or head with two throats and cutters, inclined toward each other, as is more fully hereinafter set forth.

In the drawings, Figure 1 is a perspective view of my device. Fig. 2 is a cross-section of the same; and Fig. 3 is a vertical longitudinal section, showing the relative position of the centers.

In the accompanying drawings, which form a part of this specification, A represents a metal stock or head, being a segment whose face has the cross-section of the molding that is to be produced. a are throats, inclined toward each other, as shown, and in which are secured the cutter-bits B by means of clamp-plates B’ and screws b, or in any other convenient manner. These bits have a contour at the cutting-edge adapted to produce a molding of the desired cross-section, but are designed to out in opposite directions, so that in working a curved molding either bit may be used to cut with the grain when it reverses its direction, as it necessarily does, thus avoiding the necessity of having a pair of such tools for working each pattern of molding, the one having a reverse cut from that of the other.

The handles are made detachable, as shown; but it is evident that the stock may be provided with permanent or stationary handles, if desired.

What I claim as my invention is —

The bench-tool described, consisting of the segmental head A, having the throats a a and the cutters B, secured in opposite directions in said head by the adjustable plates B’ and screw b, substantially as and for the purpose set forth.
