To all whom it may concern:

Be it known that I, LEONARD O. FAIRBANKS, of the city of Nashua, county of Hillsboro, and State of New Hampshire, have invented a new and useful Square and Bevel Attachment for Planes or other Bench-Tools; and I do declare the following is a fulland exact description thereof, reference being had to the annexed drawings.

The object of my invention is to enable persons using the ordinary bench planes to produce a square or any required bevel with certainty and despatch, Without the extraneous aid of square and bevels.

The nature of my invention consists in attaching to bench planes a clamp with an adjustable guide, and is constructed as follows: I construct a clamp A, Figure 1, of such size as will readily receive between its lugs B and binding screw C the diliierent sizes of planes, in such a manner that will secure the plane of the lugs in the square of the plane, as shown in perspective (Fig. 2). To the lugs is connected a guide plate D whose proportion is such as to secure the steadiness of a guide. At the foot of the upright A and at right angles with the face of the guide D is an adjjusting screw H which is operated by a stationary nut F. When the clamp is attached to the plane the guide plate is adjusted either at right angles with the plane stock, for the purpose of obtaining a square edge, or set at any required angle, for a bevel, by means of the adjusting nut F.

What I claim as my invention and for which I desire to secure Letters Patent is —

The attaching of an adjustable guide to the stocks of bench planes, substantially in the manner and for the purpose set forth.

To all whom it may concern:

Be it known that I, MARTIN COLTON, of Sardinia, county of Erie, and State of New York, have invented certain new and useful Improvements in Spokeshaves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference rnarked thereon, in Which —

Figure I is a bottom plan of my improvement. Fig. II is a cross section on line c–d and Fig. III is a cross section on line a–b. Letters of like name and kind refer to like parts in each of the figures.

The nature of my invention relates to the connection of an adjustable cam face to the stock of the shave in such relative arrangement to the cutting knife that by its adjustment the knife will cut in any required curve.

A, represents the stock of the shave of ordinary construction. B, represents the cutting knife connected to the stock in the cornmon manner.

C, represents the adjustable cam face in length a little longer than the cutting edge of the knife — say one inch at each end — and fitting into a concave recess or chamber made in the stock to receive it. The form of the face on the side nearest the knife and connnencing at the edge of the knife and extending about two thirds of the entire circulnference of the face — is cylindrical. That part of the cam face which bears upon the work has an expanding curvature commencing at the edge of the knife and tangent to the cylindrical part. A journal is formed at each end of the cam face upon the center line of the cylindrical part. These journals turn in eyes (D) which have long shanks (E) passing through the stock and having tightening nuts (F) upon their ends. By turning these nuts the cylindrical part of the cam face llltty be drawn into the recess in the stock and held tightly in any desired position.

In consequence of the expanding curvature of the cam face by loosening the nuts If and turning it upon its journals the distance of the line of bearing upon the work from the cutting edge of the knife may be increased or diininished — increasing it will adapt it to smoothing or cutting surfaces of greater curvature and diminishing it will adapt it to surfaces of less curvature. I am thus able to adapt the shave as required by the peculiarities of the work being done and am enabled to do the work in the most perfect manner.

I claim —

The combination of the adjustable cam face C with the stock A and knife B arranged and operating for the purposes and substantially as set forth.

To all whom it may concern:

Be it known that I, ABRAHAM S. CROSS, of Ripon, in the county of Fond du Lac and State of Wisconsin, have invented certain new and useful Improvements in Joiners’ Planes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

In the annexed drawing, making part of this specification, A represents the body or stock of the plane, which is constructed in any of the known and usual ways. Upon each end of this stock is secured a plate 1, made of metal. These plates are both provided with circular-formed slots 3.

2 represents a bent arm, which is secured through its angular portion to the plane-stock by means of a screw 5. This arm turns upon the screw 5 as a center. When the screw is tightened the arm is made fast to the stock. One end of the arm is provided with a slot 4. A set-screw 6 passes through this slot and also through the slot 3. This screw 6 is so arranged as to allow the arm 2 to partially revolve when necessary and also to station it at any desired point. By means of the slot 4. the arm 2 is enabled to turn farther than it could otherwise do, as is clearly evident, and is thus enabled, with the help of the guide 7, to form a miter.

7 is the guide upon the end of the arm for holding the plane to its position at any angle at which it is set. This guide, together with the arm 2, may be removed at any time by simply removing the screws 5 and 6, thus making the common plane of it. The end plates with this attachment may be used upon any common joiner’s plane.

I claim —

1. The combination of the arm 2, provided with slot 4, with the slot in plate 1 for the purpose of extending the slot 3 to form a miter.

2. The combination of the guide 7, the arm 2, the slotted end plates 1, and the screws 5 and 6, when the several parts are constructed and arranged in the manner herein set forth.

No. 33,589 – Improvement In Spokeshaves (John Jennings Jr.) (1861)

To all whom it may concern:

Be it known that I, JOHN JENNINGS, Jr., of Natick, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Heel or Spoke Shaves; and I do hereby declare the same to be fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1 is a top view, Fig. 2 a bottom view, and Fig. 3 a rear side elevation of a heel or spoke shave provided with my in vention. Fig. 4 is an under side view of the stock as it appears without its knife.

In the drawings, A is the stock, and B the knife, the latter being constructed witli two tangs a, a to pass through the stock. Generally the knife-tangs pass through the stock and are secured by the friction of the wood, in which case, after a while, the reception-holes become so much worn as to render it difficult to preserve the cutting-edge of the knife at its proper or desirable distance from the throat-piece b.

In making the stock I not only construct it with two tang~holes c, c, but through each tang-hole, and so as to diverge in opposite directions from it and parallel or about so to the rear side of the stock, I run or make a saw-kerf or long slit d, the same being as represented in the figures. A screw e is passed transversely through each of the said kerfs, and is screwed into that part of the stock which is in front of the kerf. Consequently when the screw is turned up so as to force its head against the stock the wood thereof will be so sprung that a firm grasp on the adjacent knife-tang may be secured. Thus as the tang-hole may become worn by movements of the tang produced by the occasional adjustment of the knife I have a means of adjusting the tang-hole or rendering it smaller.

I do not claim the application of either wedges or metallic clamps to the stock and the tangs of the knife in order to fasten the said tangs in place in the stock. My improvement has advantages oversuch, and, besides, it materially cheapens the construction of a heel or spoke shave.

I am aware that it is not new to confine the tangs of a spokeshave in place in the stock by means of screws passing transversely into metallic projections extended from the stock, the ends of such screws bearing directly against the tangs extending longitudinally through such projections. Therefore I do not claim the broad ground of confining the tangs in the stock by means of screws; but

I claim —

Tlie improved stock as made with kerfs d, dl, arranged within it and with respect to its tang-holes c, c and to receive screws, substantially in, manner and for the purpose as specified.

JOHN JENNINGS, JR.
