JOSEPH A. PERLEY, OE LYNN, MASSACHUSETTS.

HEEL AND sroKE sHAvE.

Specification of Letters Patent No. 22,889, dated February 8, 1859.

To all whom t may concern: i

Be it known that I, JOSEPH A. PERLEY, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Heel and Spoke Shaves; and lI do hereby declare that the following is a full, clear, and exact descrption of the construction and operation of the same, reference being had to the ac` companying drawings, forming a part of this specification, in which- Figure l is a perspective view showing the concave side of the knife, and Fig. 2, a perspective view showing the convex side of the knife.

Like parts are-indicated by the same letters of reference in both figures.

The nature of my invention consists in forging the blade and two Shanks in one piece, and in applying to said Shanks, beveled in a peculiar manner, an adjustable gage,-thus making the gage adjustable to the knife, instead of making, as in other shaves, the knife adjustable to the gage, shanks, or handles.

To enable others, skilled in the art, to make and use my invention, I will now describe the construction and operation of the same.

A, a, a', A, are the knife and shanks forged in one piece,-the dotted lines representing the continuations of the same driven into the handles, B, B. The general shape of the knife is shown in the figures, a being the cutting edge, and m the back. From the edge to either corner of the back is a straight line, so that, when the gage is removed, the knife can be easily ground and sharpened,-the workmanhaving a much better command of it, (by means of the handles, B, B) than he can have of a small detached adjustable blade, such as is commonly used in tools of this description.

C is the adjustable gage of wrought-iron, steel, brass, or malleable iron, and shaped as shown in the figures, the convex side being of the same curve as the convex side of the blade. The Shanks of the gage are slotted, leaving two prongs, o, c.

al, CZ, are set-screws, passing through the slots, and screwing into the Shanks of the knife, A, A, the heads of said screws bearing on the washers, o, o, which rest upon the prongs, o, o, and confine the gage at any de# sirable distance from the edge of the knife.

The side of the Shanks, A, A, (on which the prongs, c, o, of the gage rest) is not exactly parallel wit-h the convex surface of the knife, but at a small angle to it, so that the farther the gage is moved from the edge of the knife, the thicker shaving it will cut, and vice versa; and the thicker the shaving cut, the more room there will be for it to pass through over the concave side, so that the tool can never be choked by the shavings. It is also evident that my adjustable gage may be applied to a straight knife as well as to a curved one, and to a spoke, as well as a heel, shave, provided the shanks are properly beveled. j 4

By starting the screws, d, d, the gage may be quickly removed, when it is desirable to sharpen the knife, and as quickly replaced; it can also be readily adjusted, without starting the screws, by a slight blow upon the ends of the prongs, or the shoulders opposite the outer prongs. The tool is very strong, simple, cheap and easily kept in working order, while its shape is well adapted for the workman to see how he is cutting.

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

The combination and arrangement of the adjustable gage, C, and beveled Shanks, A, A, substantially as described, so that the 'gage may be moved, in a plane but slightly inclined to the convex side of the knife, to-

ward the edge, or from it, for the objects specified. j
