IMPROVEMENT IN PEG-CUTTERS.

Specification forming part of Letters Patent No. 145,714, dated December 23, 1873; application flied November 20, 1873.

To all who-m it may concern Be it known that I, CEAELEs H. BACON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Mechanism for Cutting o the Points of Pegs from the Inside of Boots and Shoes, and also for smoothing off inequalities on the surface of the inner sole, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making part of this specification, in which- Figure l is a perspectiveview, representing the casing which incloses the greater portion of my invention, the cutter for removing the pegs, and the shaft and pulley by which it is operated, being also shown. Fig. 2 is a vertical section through the center of the same; Figs. 3 and 4, sectional details to be referred to.

My invention consists in the combination, with a reciprocating cutter for the removal of pegs in the toes of boots and shoes, of a curved arm or casing, so constructed as to conform to the crimp of a bootqor shoe, and the leg of a boot, without injury to the leather.

To enable others skilled in the art to` Linderstand and use my invention, I will proceed to describe the manner in which I have carried it out.

'In the said drawings, A is a hollow curved arm or casing, of the form shown, being curved at its upper portion to correspond with the curved crimp of a boot or shoe, the lower or upright portion b being secured at its base to a suitable stand or support, B. C is a horizontal shaft, one end of which rests in a bearing, c, rising from the stand B, 'and is provided with a grooved wheel, D, which is intended to be driven by a belt passing over it, the other end of the shaft having its bearing (Z in the side of the casing, through which it projects into the interior, this end of the shaft being provided with a disk, e, having a crankpin, h, to which is secured the lower end of a lever, E. The upper end of this lever is pivoted to one extremity of a rocker-arm, G, free to vibrate on a short pin, k, passing into the sides of the casing. To the other extremity, Z, of this rocker-arm is pivoted the lower end of a lever, H, to the upper end of which is pivoted a plate, I, having its under side provided with two lugs, nl., between which iits the upper end of the lever H, the form of the plate in cross-section being that shown in Fig. 3. The curved portion c of the casing is open at its top, upon. which is screwed a iiat plate, K, provided with an opening of nearly corresponding size and shape as that in the top of the casing. L is a block, provided with sharp edges, and secured to the plate I by a screw, n, and dowel-pin o, the block serving as a cutter for removing the points of pegs which project up from the inner sole into the interior of a boot or shoe, and also for smoothing off any inequalities on the upper surface of the inner sole, to render it easy for the foot. To the top of the casing is secured a strip of metal, which projects up at the sides of the cutter L a distance of about half of its thickness, and is intended as a guard, p, for protecting the upper leather from any possible injury from the cutter.

From the foregoing construction, it will be seen that the cutter, through the connections above described, is made to move forward and back on the plate K at the top of the casing, and, when a boot is applied thereto,

the points of the pegs projecting from the inner sole at the toe or other portions of the boot or shoe are brought into contact therewith and rapidly removed, it being simply necessary to guide and turn the boot or shoe by hand, so as to bring the line of the pegs upon the reciprocating cutter. 1

Instead of two levers connected by a rockerarm for moving the cutter L, a single lever bent to fit the interior of the casing may be employed, and an eccentric, r, may be substi` tuted for the disk e and crank-pin h, as seen` in Fig. 4, if desired, without departing from the spirit of my invention.

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

The bent arm or casing A, inclined so as to accommodate the crimp and leg of the boot, and pass to the toe, in combination with the reciprocating cutterL, with its operating mechanism, substantially as and for the purpose set forth.

Vitness my hand this l18th day of Novem ber, 1873.

C. H. BACON.
