To all whom it may concern:

Be it known that I, EAMOR A. TEED, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Bench-Planes, of which the following is a specification.

My invention relates to bench-planes; and it consists in the means, hereinafter described, whereby the stock of the plane may in effect be lengthened to enable one plane to serve the purpose of one or more planes of greater length than the plane to which the improvement is applied.

In the accompanying drawings, Figure 1 is an isometric perspective view of a plane with my improvement applied thereto; Fig. 2, an isometric perspective view of my improvement detached; Fig. 3, a vertical cross section on the line x x in Fig. 5; Fig. 4, a central longitudinal section of the rear part of the plane proper and the rear part of my improvement; Fig. 5, a central vertical section of my improvement and a side elevation of the plane.

The improvement, hereinafter described, may be applied to any so-called “iron bench-plane” — that is, a bench-plane having an iron stock — and is here shown as used in connection with a “Bailey smooth-plane,” the construction of which is well known and needs no particular description.

lt is sufficient to say that A represents the stock, a the plane-iron, and H H’ the plane-handles.

The only change that requires to be made in the plane proper to enable my improvement to be applied to it is to form two grooves, a’, one on each side of the stock leading from near the point of the same to said point, and providing the handle H’ with a depression, h, for purposes hereinafter stated.

My improvement consists of a shoe, S, which in general appearance is like the bottom and sides of the stock, but longer, and provided with an opening, s, through the bottom of the same, of a shape and size adapted to receive and fit the sole of the stock A. The shoe S is provided with pins s’, (shown in Figs. 2, 3,and 5,) adapted to enter the grooves a’ and to fit the same, and is also provided with a vertical post, s2, arranged in the rear of the slot s, which vertical post supports an inclined screw, s3, the head s4 of which is preferably milled to enable it to be turned readily by the fingers, the point of said screw entering the depression h, above mentioned as being formed in the handle H’, to prevent the rear end of the plane from rising out of the slot s. The relative positions of the grooves a’, pins s’, screw s3, and depression h, are such as to hold the sole of the stock A and the bottom of the shoe S in the same plane, the rear ends of the grooves a’ being at the same height above the sole of the stock as the pins s’ are above the bottom of the shoe, and the deepest part of the depression h fitting the point of the screw s3 and being at the same height above the sole of the stock as the point of said screw, when turned into said depression, is above the bottom of the shoe. The depression h, instead of being made directly in the wood of the handle, is preferably made in the head of a metallic screw, h’, driven into the handle against the screw h2, which secures the handle H’ to the detachable face-plate.

The plane is inserted in the shoe-point first and pushed forward until the pins s’ reach the rear ends of the grooves a’, and the rear of the plane is then depressed until the lower surfaces of the stock A and the shoe S are in the same plane. loosening the screw s3 the rear end of the plane may be lifted out of the slot s, and the stock being then drawn backward is disengaged from the shoe.

By means of the improvement above described a common smooth-plane can be used with the shoe as a fore-plane or jointer, and the expense of such a shoe is trifling compared with the cost of a plane, and the time required to apply or remove the shoe is of no importance.

I claim as my invention —

1. A shoe provided with a slot adapted to receive a plane-stock and means, substantially as described, of holding the bottom of said shoe in the same plane with the bottom of said stock, as and for the purpose specified.

2. The combination of the plane having a handle, and having a stock provided with grooves near its point, and a shoe slotted to receive said stock, and having inwardly-projecting pins adapted to enter and fits said grooves, and having a post, a screw turning in said-post and thrusting into a depression with which said handle is provided to hold the lower surfaces of said stock and shoe in the same plane, as and for the purpose specified.

Corrections in Letters Patent No. 371,482.

It is hereby certified that the name of one of the assignees in Letters Patent No. 371,482, granted October 11, 1887, upon the application of Eamor A. Teed, of Lowell, Massachusetts, for an improvement in “Bench-Planes,” was erroneously written and printed “Frank B. Low,” whereas said name should have been written and printed Frank B. Dow. Also that errors appear in the printed specification requiring correction as follows: In line 75, page 1, the word “face-plate” should read shoe and in line 76, same page, the hyphen between the words “shoe” and “point” should be stricken out; and that the Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Office.

To all whom it may concern:

Be it known that I, JAMES H. POLHEMUS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Spokeshave, of which the following is a full, clear, and exact description.

My invention relates to an improvement in spokeshaves, and has for its object to provide a tool capable of use as readily in curves of small radius as upon a flat surface.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully described, and set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my spokeshave, and Fig. 2 is a central transverse vertical section through line x x of Fig. 1. Fig. 3 is a horizontal section through the central portion of my tool, with the clamp removed and the surface of the blade exposed.

At each side of the central portion of the tool A, having the ordinary handles, a, and transversely the said tool, vertical ears B are formed, provided near their upper edge with a segmental slot, b, and a parallel integral transverse offset, C, upon their inner face at the base, which offset is more or less concaved at its outer end.

In the body D of the tool, intervening the ears B, a more or less V-shaped central recess, d, is produced, which recess is out entirely through said body at the inner end thereof, as illustrated at d’ in Figs. 1 and 3. Within the recess d a pin, e, is secured, upon which pin an angle-lever, E, is pivoted at the intersection of its arms, the short arm of said lever being adapted to reciprocate in the recess d, and having a stud, F, made integral with its upper face near the end, the long arm of said lever being provided with a thumb-rest, f.

A knife, G, having a central slot, g, is made to slide in the body surface D between the transverse offsets C of the ears B. The knife G is also provided with a series of small rectangular slots, H, arranged to the rear of the large slot g, in central alignment therewith, about the sixteenth of an inch intervening each of said small slots, and also the foremost one and the large slot g. When the knife is inserted, as aforesaid, the stud F upon the angle-lever is made to enter the first or foremost rectangular slot H, as shown in Figs. 2 and 3. As the knife becomes narrowed by sharpening and use, the remaining slots H may be brought into contact with the stud F.

The object of the lever-connection with the knife is to adjust the knife-edge, as in a plane, the desired distance over the front edge of the body surface D.

A clamping-plate, K, of substantially the same shape as the knife, provided with an outer beveled edge, k, and a central elongated slot, k’, is made to rest upon the knife G, clamping the same in a given position by means of a screw, L, which, passing through the slot k’ of the clamp-plate and the large slot g of the knife, is screwed into the body D, as shown in Fig. 2.

A guide, M, consisting of the longitudinal bar m, having a flat under surface, m’, and more or less round corners, m2, and provided with integral arms m3 at right angles thereto, is adjustably held within the ears B by thumb-screws N, entering the slots b in said ears and also the arms m3 of the guide at their ends. When the guide M is thus positioned, the flat under surface m’ thereof is normally in the same horizontal plane with the under flat surface n of the body D. A space is, however, made to intervene the opposing edges of the said body D and the guide.

In operation, by pressing with the thumb against the lever E the knife is adjusted as desired and set by the body-screw L. If a plain surface or curve of large radius is to be dressed, the arms of the guide M are secured in the upper corners of the segmental recesses b, as shown in Fig. 2. In this position the device acts as an ordinary tool of its kind. When, however, it is desired for use upon a curve of small radius, the arms of the guide are carried as far down the slot as thought proper, which action throws the under surface of the guide at an angle to the flat under surface of the body, permitting a manipulation of the tool in short curves or in apertures large enough to admit the tool.

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

1. In a spokeshave, the combination, with the body D, provided with the ears B, having curved slots b, and the blade adjustable on the upper face of the body D between said ears, of the guide M, consisting of the longitudinal bar m, pivotally connected at its ends to the ears B adjacent to the lower end of the blade, and formed with the arms m3, having threaded apertures in their upper ends, and the set-screws N, passing through the slots b into said apertures, substantially as set forth.

2. In a spokeshave, the combination, with the body D and a guide, of the blade G, having slots H g, the lever E, pivoted to the body and having a stud, F, entering the slot H, the clarnping-plate K, having a. slot, k’, and the set-screw L, extending through the slots k’ g into the body D, substantially as set forth.

3. A spokeshave comprising the body D, having the V-shaped slot d’ in its upper face, the ears B B, having slots b, the U-shaped guide M, pivoted at the lower ends of its side arrns, m3, to the lower ends of the ears, and set-screws passed through the slots b into the upper ends of said arms, the lever E, pivoted at e within recess d’, and having a pin, F, the blade G, having a slot, g, and a series of slots, H, into one of which pin F projects, the clamping-plate K, having a slot, k’, and the set-screw L, passed through the slots k’ g into the body, substantially as set forth.

_________________

To all whom it may concern:

Be it known that I, EDWARD B, SHEPARDSON, a citizen of the United States, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Gages for Wood-Working Planes; and I 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 is an improvement in gages as attachments to woodworking planes; and it has for its object to provide an attachment to planes of hollow metal construction, one part of which is adjustable about an axis of motion to any required angle with reference to the bottom surface of the plane to which said gage is attached, so that a guide will be formed to fit against one surface of the material and slide against the same as the bottom of said plane rides over an edge of said material, cutting the same and forming an angle with reference to anotherside of said material greater or less than a right angle.

Mechanics who are in the habit of using wood-working tools are familiar with the difficulties encountered in beveling the edge of a board where the eye and feeling or judgment alone are depended upon in making the required angle. It is desirable, in view of such difficulties, that a good and simple device be provided, so that the operation of beveling may be only mechanical. Such devices have been invented, I am aware, as applicable to planes the stocks of which are of wood. My gage is intended to be applied to a plane the stock of which is of metal. My gage is formed, in the main, of two pieces of metal hinged together. One of said sections consists of a horizontal bar having at each of its two ends projections of T form, the bar, with its two ends, forming an H, as seen from the outside. Each of the T ends is bent inward nearly at right angles. The upper of these bent ends forms lugs for clamping-screws, and the lower of said bent portions is slotted and connected by a bracing-bar. The lower part of the gage is composed of a bar of U shape, the inner plane-surface of which is smooth, and the ends of said bar form tongues, which enter the slots in the upper portion of said gage where the two said parts are hinged together. Bifurcated pieces, forming clevises, project outward from the H -bar and the U -bar, and in these are pivoted or hinged screw-threaded nuts. A right-and-left screw provided with a thumb-piece on its center engages these nuts, and when operated increases or diminishes the angle between the two parts of the gage.

In my drawings, Figure 1 is an elevation of the gage as seen from the outside. Fig. 2 is a transverse vertical section of the same, showing the application of the gage to a plane and the relation of the latter to a piece of material being beveled.

Similar reference-letters indicate like parts in both of the figures.

Referring to the drawings, A is the horizontal bar of the upper portion of the gage, and B B’ are the T ends ofthe same, provided with bent portions a a’ b b’, the latter of which are connected by the strengthening-bar C.

d d’ are slots formed in the bent ends b b’, which receive the tongues e e’ of the lower portion of the gage.

D is the lower portion of the gage, formed as previously stated, the tongue ends of which are hinged in the slots of the T-pieces B B’. The long bar of the upper portion of the gage and the curved bar of the lower portion of the same have projecting from their centers outward bifurcated pieces or clevises E E’. In the outer ends of these clevises are pivoted swivel-nuts f f’, adapted to receive the right and left ends of the double screw F.

The bent T ends a a’ have screw-threaded openings to receive the screws G G’, the clamping ends of which latter may be threadless.

In applying this gage to a plane I place the bent portions a a’ on one of the side walls, with the long bar A resting against the outside of said wall and the clamping-screws — not yet driven down — against the inside of the same. The gage should be so placed upon the plane that one of the clamping-screws shall be in front of the handle and the other rearward of the same. When the screws are driven down to place, they impinge upon the bottom plate of the plane and draw the bent ends b b’ of the gage up against the bottom surface of said plane, and the gage is thus firmly held to place.

It may be observed that the interior angles between the T-pieces and portions a a’ are less than right angles, so that the screws when driven home find their places in the angle of the plane formed by the inner surface of the bottom and the inner surface of the said side wall. The gage being thus firmly secured to the plane, when the angle of the bevel to be made is determined the lower or U -shaped bar of the gage is moved about its axis by the right-and-left screw G G’ until the proper angle is formed. The gage is now applied with the plane to the piece of material to be planed in such a manner that the inner surface of the U-shaped bar rests against one side of said material and the bottom surface of the plane upon the edge of the same to be beveled.

The operator has only to keep the gage upon the guiding-surface of the material as he operates the plane to insure accurate work.

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

In a gage for use with wood-working planes, the combination, with the upper portion provided with clamping-screws, a swivel-nut, and jaws or bearings for the same, of the lower portion of said gage hinged to the said upper portion, provided with a swivel-nut and jaws or bearings for the same, and the right-and-left screw engaging said swivel-nuts to adjust the two portions, the one with reference to the other, as and for the purpose set forth.

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

To all whom it may concern:

Be it known that I, LESTER A. DEARTH, of Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Hand or Jack Planes, of which the following is a specification.

My invention relates to jack or hand planes, and has for its object to provide improvements in devices of that kind whereby the sole of the plane may be oiled (as is necessary in some classes of work) during the operation of smoothing or planing lumber therewith, and without the necessity of stopping work and employing a device separate from the plane itself for that purpose.

As is well known to carpenters, joiners, and others skilled in arts requiring the use of planes, it is essential in many kinds of work to oil the sole of the plane, and in instances where this thing is necessarily frequent much time is consumed thereby, as well as annoyance occasioned to the workman.

In carrying out my invention I utilize the knob secured to the upper face of the stock just in front of the slot provided for the escape of shavings as an oil-reservoir, in addition to its present uses, and combine means with said knob whereby the workman can from time to time, and while using the plane in the ordinary manner, supply oil to the sole thereof as may be needed.

I will now proceed to describe my invention, so that others may be able to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification, the same letters indicating the same parts wherever they occur, and the invention being particularly pointed out in the claims hereunto appended.

Of the drawings, Figure 1 represents a perspective view of a plane having my improvements applied thereto. Fig. 2 is a longitudinal vertical section thereof.

A indicates the plane-stock, provided with the usual handle, B, and cutting iron or tool C, adjustably secured to operate in the slot D, provided for that purpose and for the escape of shavings.

E represents the knob applied to planes as new commonly constructed, which knob is attached to the stock just in front of slot D. I construct knob E of metal or other suitable material and make it hollow, as represented in Fig. 2, providing the interior with a short tube, e, extending up from a central point at the bottom thereof, and form a hole of desired size in the top over tube e, the hollow of which latter feature extends through the bottom of the cup.

f represents a stem adapted to fit closely in tube e and to slide thereon, a spiral spring, g, surrounding said stem above tube e, and bearing at its lower end on the upper end of said tube and pressing at its upper end against a pin, h, extending through the stem, whereby the stem f is pressed upward in the tube, pin i, extending from the stern through a slot, j, in the tube, serving to limit both the upward and downward movement of the stem.

k represents a plug constructed to closely fit and slide in the hole formed in the upper end of the knob, as aforesaid, and adapted to be screwed into the upperend of stem f, or otherwise connected therewith, which plug serves both as a stopple to the hollow knob and affords means for gaining access to the interior thereof and as a contrivance whereby stem f may be depressed against the tension of spring g, operating as hereinabove explained.

f’ represents a packing of any suitable character arranged in a groove formed in plug k, or between two disks comprising the same, whereby the plug may be made to fit the hole in which it works in an oil and air tight manner. A small hole or bore, l, is made in stem f which hole extends vertically upward for a short distance from the lower end thereof, and then horizontally outward through the side of the stem, and a hole, m, is formed through the side of tube e, at the lower end thereof, constituting a valve, all as clearly represented in Fig. 2, the construction and arrangeinent of these last mentioned features being such as that when stem f is depressed by bearing on plug k bore l will be brought into range with hole m, and oil with which it is designed to fill knob E (made into a cup, as explained) will flow through said bore and down through a hole, n, formed in the stock to the sole of the plane — in the present instance shown to be just ahead of the cutting-tool.

The manner of using the invention will now be readily understood. The knob being filled with oil and the parts being arranged in position, as shown, the operator from time to time, as it may be necessary to oil the plane, as aforesaid, and without stopping his work, depresses stem f for a moment by pressing a thumb or finger thereon, releasing a drop or so of oil, which runs down through hole n, in the stock to the proper point on the sole of the plane.

By the means explained a material amount of time is saved to the workman, and by utilizing the knob common to nearly all classes or kinds of planes my invention is made cheap of construction and ready of application, as well as convenient in use.

Although I have been particular to describe the precise form and arrangement of the parts as here comprising my improvements, it is obvious that these may be varied within the limits of mechanical skill without departing from the nature or spirit of my invention.

Having thus described my invention, what I claim is —

1. In a plane, the combination, with the stock, of the knob thereon, made hollow or formed as an oil-cup, a valve in said knob or cup, and a spring-pressed stem or plug extending to the exterior of the knob, whereby the valve may be operated to release oil from the cup to oil the sole of the plane, as set forth.

2. In a plane, the combination. with the stock, of the knob thereon, made hollow or formed as an oil-cup and provided with the tube e, having hole m, and spring-pressed stem, f fitted to slide in said tube and provided with bore or hole l, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 19th day of March, 1887.

To all whom it may concern:

Be it known that I, SAMUEL BENSON, a citizen of the United States, residing at Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented certain, new and useful improvements in Spokeshaves; and I 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in spokeshaves, the object being to provide a means whereby the blade may be easily adjusted or detached from the handle of the tool; and with this end in view my invention consists in certain details of construction and combination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of my improved spokeshave constructed in accordance with my invention. Fig. 2 is a rear side elevation of the same. Fig. 3 is a perspective view of a portion of the blade, showing the projecting end used for securing the blade to the handle. Fig 4 is a perspective view of one of the bolts for attaching the blade to the handle.

To put my invention into practice and give the same bodily form, I provide a handle, a, of suitable size and form of construction, having a metallic plate, b, embedded into the same immediately back or at the rear of the cutting-blade c. This plate b is a wear-plate, and prevents undue wear of that part of the tool which bears upon the spokes in the operation of shaping them. At the front of this plate b, I place the knife or blade c, mounted on two small horizontal plates, d, secured a short distance below the general level of the handle a. On each end of the knife cis formed a projecting flange or lug, g, which, in conjunction with two flat-head bolts, k, placed at either end, affords a means of securing the knife or blade c to the handle a. By shifting this knife c back from the inlaid plate b a coarse shaving is taken from the work; or the knife c may be elevated by placing small strips of paper or other substance between the plates d and the projecting flanges g of the knife c. This knife or blade c may be readily taken from the handle a for the purpose of sharpening or grinding, by loosening the thumb-nuts l on the end of the bolts k.

I am aware that it is not new in spoke-shaves to secure the knife to the stock by slipping its ends into grooves formed in the stock and using at one end of the knife a clamping-bolt. I therefore disclaim such a device.

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

ln a spokeshave, the combination consisting of the handle a, having a metallic plate, b, embedded therein, the knife or cutting-blade c, provided at either end with flat projecting flanges g, the horizontal plates d, and flat-headed bolts k, provided with thumb-screws l, substantially as and for the purpose set forth.

_________________

To all whom it may concern:

Be it known that I, JOHN BRICE, a resident of Sandy Hill, in the county of Washington and State of New York, have invented certain new and useful Improvements in Bench-Planes; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in bench~planes, and its object is fully explained in connection with the drawings.

The invention consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims.

Figure 1 of the drawings is a top plan view of my improved plane. Fig. 2 is a vertical longitudinal section taken at the broken line x x in Fig. 1. Fig. 3 is a top plan view of my improved locking-lever. Fig. 4 is a side view of same. Fig. 5 is a plan view of attachment d detached.

Similar letters refer to similar parts in the several figures therein.

Numerous devices have been heretofore constructed for angularly adjusting the bit of a bench-plane and for securing the same in place in its frame or stock. They have generally been complicated in structure and expensive of manufacture, requiring special and differing forms of structure in the stock, the latter being generally made of metal.

In the construction of my improved device I am able to make use of the old and well-known wooden stock so generally in use, as well as the bit, or bit and back plate, used in connection therewith, and thus greatly improve such planes with very little expense.

My improved planes can also, when desired, be made wholly of metal or any other desirable material.

A is the stock, made in the well-known form usually adopted for wooden stocks, having the chip-opening E, inclined bit-abutment F, and upwardly-widening rearwardly-inclined side recesses, a’ a’, forming inclined ledges a a on each side of the chip-opening.

The bit B, which has a back plate, C, secured thereto by a set-screw, g, adjustable in its slot b’, is inserted through the opening in the usual manner, as shown.

Instead of driving a wedge down between the bit or plate C and the projecting ledges a a, to bind the bit in place, as has been done heretofore in such stocks, I make use of the locking-lever D, preferably metallic, and in the form of a plate convened on its upper side, substantially as shown.

I slide the lever down between the back plate, C, and the ledges a to about the position shown in Figs. 1 and 2.

The side of the lever contiguous to the plate C may have its surface plane or concave, as shown by dotted line in Fig. 4; but the opposite side contiguous to the ledges is convexed. The degree of convexity may be varied as desired.

At or near one end of the lever I provide the aperture f, preferably threaded, and adapted to receive the threaded adjusting screw b, the screw passing down through the aperture and resting upon the bit or its plate C.

When desired, a threaded nut, n, (shown by dotted lines,) may by employed, when it will not be necessary to thread the aperture in the lever.

By means of the adjusting-screw the upper end of the lever can be forced away from the plate C, the lower end of the screw resting upon the plate, and the lever traveling up the thread of the screw until the parts are securely locked in place, the central portion of the convexed lever ending a fulcrum upon the ledges a a, and the lower end of the lever bearing upon the lower end of the bit or its plate. I am able also to secure an angular adjustment of the bit by means of the attachment or plate d, extending above the top of the stock, provided with the adjusting-screw e, threaded to fit the threaded aperture i, having a head, e’, on which the bit has bearing. This attachment is preferably countersunk in a longitudinal recess, a”, in the upper or rear portion of the abutment F, to occupy a position about parallel with the bit, and may be secured by screws d’, passing through apertures j, as shown.

The upper end or head of the screw bears against the lower side of the bit, and when operated forces the bit up to the desired angle, the screw b being turned back, as required.

The convexity of lever D permits the angular adjustment of the bit to any desired degree without impairing the perfect operation and effectiveness of the lever as a locking device.

I am thus able to produce a new and improved plane by adding the loclring-lever D, with screw b, and the attachment d, with screw e, to a common and well-known device.

I do not broadly claim an angularly-adjustable bit nor a bit-locking lever.

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

1. The combination of the stock A, formed with a chip-opening, E, inclined rear abutment, F, having correspondingly-inclined longitudinal recess a”, upwardly-widening inclined side recesses, a’ a’, forming inclined front abutments, a a, projecting into the chip-opening, the fixed plane plate d, secured in the longitudinal recess and projecting above the stock, an adjusting-screw, e, inserted in the projecting portion, having a head, e’, a bit, B, supported on the inclined rear abutment and on the head of the adjusting-screw, the back plate, C, adjustably secured to the bit, and the lever D, located at the rear of the chip-opening, having a convex upper side bearing against the front abutments, its lower end bearing on the lower end of the back plate, and an adjusting-screw in the upper end of the lever bearing on the middle portion of the back plate, the bit, back plate, and lever all being of the sanie width and the side recesses being common to all, substantially as shown and described.

2. The combination of the stock A, formed with a chip-opening, E, longitudinal recess a”, and upwardly-widening inclined side recesses, a’ a’, forming inclined front abutments, a a, projecting into the chip-opening, the fixed plane plate d, having an adjusting-screw, e, a bit, B, a back plate, C, and the lever D, located at the rear of the chip-opening, having a convex upper side bearing against the front abutments, its lower end bearing on the lower end of the back plate, and an adjusting-screw in the upper end of the lever bearing on the middle portion of the back plate, the bit, back plate, and lever all being of the same width and occupying the side recesses common to all, substantially as shown and described.

In testimony whereof I have hereunto set my hand this 12th day of March, 1886.

ROUTING-TOOL.

SPECIFICATION forming part of Letters Patent No. 356,429, dated January 18, 1887.
Application filed June 22, 1885. Serial No. 169,356. (No model.)

_________________

To all whom it may concern:

Be it known that I, HENRY F. STEARNS, a citizen of the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Routing-Tools for Workers of Wood, of which the following is a specification.

My invention relates to improvements in routing-tools in which the stock is provided with a mouth having on one of its sides a way for holding the cutting-tool and a wedging-piece and an adjustable gage working in the arms of the tool, all of which I will hereinafter particularly describe and set forth; and the objects of my invention are to provide in a routing-tool adjustable and interchangeable cutting-tools, which will be securely held from shifting in the mouth of the tool and have the gaging devices adapted to be variously adjusted and set at either right or left hand side of the cutting-tool and at any desired distance therefrom as the work to be done may require. I attain these objects by the mechanism illustrated in the accompanying drawings, in which —

Figure 1 is a view of the tool from above. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is a cross-section taken at line 1 in Fig. 1. Fig. 4 is a view of the mouth of the stock with the cutting-tool and wedge removed, and showing the tool-guiding way. Fig. 5 is a plan view of a cutting-tool and an end view of the same, showing the coacting way made therein.

The same letters of reference refer to like parts throughout the several views.

The stock A, arms A’, and handles A2 A2 of this tool may be made in one piece of malleable iron, or be made of wood and iron combined, if preferred. The stock A is made with a gradually-contracting mouth, B. Across the upper portion of this mouth, and arranged slightly to one side of the center of its width and running longitudinally in direction of arms A’, is bar b, preferably made solid with the end walls of said mouth, or securely fixed therewith. Made with the rear side wall, a, of this mouth is the way c, which is shown in Figs. 3 and 4 to project a short distance past the plane of said rear wall.

C is the cutting-tool, made with any form of cutting bit or edge usually employed for grooving, channeling, beading, or forming moldings, or for incising. Made central in the width of this cutting-tool and in its rear side from its upper end, or near the cutting bit or edge, is the way c’, corresponding in size and form with way c, made with the rear wall, a, of mouth B, so that the former will receive the latter and permit the shank of the tool to have a full bearing on the surface of wall a of the mouth of the tool. These ways may be made to be reversed in their respective forms by making that in wall a of mouth B in the form of a groove instead of a projection, as shown, and that in tool C in the form of a projection instead of a groove, as shown. These ways c c’ in the respective pieces co-operate together to hold the cutting tool or blade C from shifting or being moved out from its normal set position in the mouth of the stock, and allow a variety of tools or blades, C, of differing widths to be employed within mouth B without the least liability of shifting when the tool is being operated.

D is the wedge, having a shallow groove, d, running across its front side, as shown in Fig. 3, for engagement with holding-bar b. The lower end of this wedge is made with an incline, as shown in the same figure, so as to permit an opening between the tool or blade below and the front wall of mouth B, for passage of the shavings from the cutting bit or edge of the blade C. In the upper end portion of this wedge D is made a screw-threaded hole, into which works the set-screw f by which, through wedge D, the cutting tool or blade C is securely held in its adjusted position and length of projection below the sole or face m, of the stock, which face is curved in its surface. Made in arms A’ A’ are slots E E, extended to any preferred distance from stock A toward handles A2.

F is an adjustable gage-lip provided with a projection, g, which nicely fits in slots E, for holding with the same to prevent the gage-lip from shifting sidewise. This projection is made with tail-piece F’ of the gage-lip, and has projecting upward from it the screw-threaded stem h. Nicely fitting this stem h is the screw-threaded finger-nut H, for securing this gage-lip at any point distant from the cutting tool or blade C. This gage-lip and its holding device are adapted to be used in the slot E of either of the arms A’, as may be required for right or left hand work.

By my above described improvements I obviate the use of several different bodies of routing-tools as heretofore required by carriage-makers, cabinet-makers, and other workers of wood for different operations or kinds of work, and with a variety of cutting blades or tools, C, provided each with a suitable form of cutting edge or bit, a workman can form in the wood on straight or curved lines, and on the right or left hand edges of the pieces, grooves, channels, beads, moldings, flutings, or other raised or sunken surfaces, as may be required.

The mouth of the router, being arranged to be vertically over the cutting-bit of tool C, will deliver the shavings upward from the same in a free manner instead of in a forward direction, as is usual in routers heretofore made, and the shavings will be freely delivered from the cutting-bit and without the least liability of choking the tool, as heretofore. The coacting ways c c’, made with the rear side wall of the mouth of the stock and the rear side of the shank of the cutting-tool C, operate to hold that tool firmly from shifting in any direction, and the bar b, operating with the groove d of wedge D, holds the latter from moving in either direction end wise, While the wedge D, with the set-screw f operates to hold the tool or blade C secure to its place, with its cutting-edge projecting below the sole of the stock to the point adjusted to without the least liability of its being raised, and also allows this cuttlng-blade to be readily set to cut deeper from time to time, as may be required in the progress of the work.

The spokeshave-blade can readily be applied and be firmly held and shifted in either direction in relation to the month of the stock A. The stock, with its slotted arms and handles, operating to serve as the body of a spoke-shave, being well adapted to receive the above-described shaving-blade S, obviates the use and expense of a special and individual stock, as heretofore required.

The stock A and its mouth B may be made of any suitable length, so as to receive two or more cutting-tools, C, for grooving or incising or beading two or more surfaces at a time, as may be preferred. The curved surface of face m of the stock running from one side to the other enables the operator, by slightly turning the stock, to cut with a greater or less depth into the wood, and thereby obviates the necessity of setting the cutting-blade C (for making different depths of cuts) several times before finishing the work being done.

If preferred, a small bracket, z, made with the rear side of the stock, and provided witli a set-screw, x, working in its head end, and its lower end working in a small sleeve attached to the upper end of the tool C and held by a key, may be employed ibr raising or lowering the tool, as is the practice with irons in planes.

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

In a routing-tool, the combination, with a stock provided with similarly-slotted arms, which are extended in opposite directions from the tool mouth, of an adjustable gage-lip, which is provided with a screw-threaded stem and nut and constructed to be used interchangeably in said slotted arms, a cutting-blade which is provided on its rear side with the way c’, which engages with way c, made with the rear side wall of tool-mouth B, and the mechanism described for adjusting and securing said cutting blade in said tool-mouth, substantially as and for the operations and purposes set forth.
