To all whom it may concern:

Be it known that I, FREEMAN KILLBRITH, of Pembroke, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement on an Implement or Tool called the “Edge-Plane,” Used for the Pairing or Trimming the Edges of Boots and Shoes; and I do hereby declare the following is a full and exact description of said tool, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in attaching to the shank of the edge plane a movable guard which by means of a screw and slide can be moved toward the edge of the knife as the knife wears away by use, so that the space between the edge of the knife and the guard can be regulated at pleasure; and also in making the knife itself movable so that it can be set at any desired gage, and also be removed from the shank entirely to be ground or sharpened.

To enable others to make and use my invention I proceed to describe its construction and operation, reference being had to the accompanying drawings.

A is a common wooden tool handle in which is inserted solid in the end, the iron shank B to which is attached the guard C and the knife D.

C is a movable guard fastened to the shank B by the screw e and which can be moved from right to left as desired and held in its place by the screw e or wholly removed from the shank B.

D is the knife fastened to the shank B by I the screw f which works in a slot in the knife, so that it can be raised or lowered and set to any required gage or by unscrewing entirely be removed from the shank to be ground or sharpened.

To operate this tool with this improvement, when the edge of the knife is worn away by use, by loosening the screw e, the guard C can be moved to the left to the edge of the knife D and by tightening the screw e set at any required distance from the edge of the knife D.

To set the knife to any gage for paring a sole the screw f is loosened and the knife raised or lowered to the desired gage and the screw fastened.

To remove the knife from the shank, remove the screw f wholly.

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

The attachment to the edge plane now in use and known as Dunham’s patent, of the movable guard C with its screw e, the guard being movable to and from the edge of the knife D, and sliding on the face of the shank, B; and also the attachment to the shank B of the knife D with its screw f working in a slot, and raised or lowered to any desired gage for paring soles, and which knife D can be wholly removed from the shank B by unscrewing the screw f, and so ground or sharpened, and be replaced by a new knife if necessary.

No. 23,927 – Spoke Shave (Benjamin Tolman) (1859)

SPOKE-SHAVE.

Specification of Letters Patent No. 23,927, dated May 10, 1859.

To all whom it may concern:

Be it known that I, BENJAMIN TOLMAN, of Pembroke, in the county of Plymouth and State of Massachusetts, have invented an Improved Spoke-Shave or Heel-Shave; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which —

Figure 1, denotes a top view of it. Fig. 2, an underside view of it. Fig. 3, a front side view of it. Fig. 4, a rear side view of it. Fig. 5, a transverse and central section of it. Fig. 6, an underside view of its adjustable throat gage to be hereinafter described.

In the drawings, A, exhibits the stock or handle of the shave; B, the curved knife, while C, is the throat gage, the said knife and throat gage being constructed of metal. In spoke shaves or heel shaves as ordinarily constructed, the knife is furnished with “starts” or adjusting contrivances, which extend transversely through the handle, and cause the knife during the process of adjusting it, to be moved either toward or away from the stock. In consequence of this mode of arranging the adjustments, the knife, while the shave is being used, is very apt to be moved toward the stock or get out of place, for the great pressure employed to keep the tool in contact with the article to be shaved is borne mostly and directly by the knife and in such manner as to render the knife liable to be forced up to or toward the handle. In the construction of my improved shave I have avoided this liability of derangement of the knife. The two ears, a, a, of the knife, are not provided with starts to extend through the handle, but are formed so as to rest with broad bearings or surfaces upon flat surfaces or plates of metal, D, D, screwed or fastened lirmly to the stock, each of the said ears being provided with a slot, b, arranged transversely in it, and for the reception of one of two clamp screws, c, c, which is passed through it and screwed into the bearing plate, such clamp screw having its head projecting over the opposite sides of the slot in order that when screwed down firmly it shall confine the ear in place on the bearing piece. In connection with the said movabllie and adjustable knife, I employ an adjustable throat gage, C, which is formed as shown in the drawings, is fastened by screws f, f, to the front side of the stock. It also extends in front of the knife and between the latter and the stock, as shown in Fig. 5. The screws, f, f, pass respectively through elogated slots g, g, made in the adjustable gage C, the same being so arranged as to enable the gage C, to be moved in a direction at a right angle to that in which the knife is capable of being moved.

The object of adjusting the knife as described is to enable the cutting edge h, to be brought into a suitable position with respect to the rear edge of the bearing part, i, of the throat gage, for it will be observed that in proportion as the knife is worn down by the act of sharpening or grinding it, it will require to be moved forward. Furthermore, the object of making the throat gage adjustable is, to regulate the depth of cut or thickness of shaving to be taken by the knife.

From the above, it will be seen that the knife having been once adjusted and clamped firmly on its bearing plates cannot easily be thrown out of place while in operation, and besides this the adjustment of the distance between the knife and the throat gage can be made without disturbing the knife. As most of the pressure by which the tool is borne against an article while in the act of cutting the same, is borne by the knife, there is little or no danger of derangement of the throat gage.

I do not claim a shave made with a stationary knife and an adjustable gage; nor do I claim a shave as made with an adjustable knife and a stationary mouthpiece disposed in front of the knife, but what I do claim as my invention is —

An improved spoke shave, constructed substantially as herein before described, that is with an adjustable knife and an adjustable throat gage, arranged and applied to the stock, and so as to move with respect to one another as specined.

In testimony whereof I have hereunto set my signature this twenty eighth day of September, A. D. 1857.

BENJAMIN TOLMAN.
