IMPROVEMENT IN MACHINES FORCUTTING OFF Pres m BOOTS AND SHOES. I

Specification forming part of Letters Patent No. 140,803, dated July 15, 1873; application filed May 27, 1873.

To all whom it may concern:

Be it known that I, AMos WHITTEMoRE, of Oambridgeport, county of Middlesex and State of Massachusetts, have invented a new and Improved Machine for Cutting Off Pegs in Boots and Shoes; and'l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, in which Figure l is a side elevation of my peg-cutter. Fig. 2 is a vertical Section through the same in a horizontal position; Fig. 3 is a view, similar to Fig. 2, showing the cutter inclined.

. Fig. 4 is a top view.

Similar letters of reference indicate corresponding parts in the several figures.

The objectof this invention is to improve peg-cutters, which are constructed with rotary cutting faces, as will be hereinafter explained.

The following description will enable others skilled in the art to understand it.

In the accompanying drawings A represents the cutter-stock, which is Shaped somewhat like a shoe, with the sole turned upward, and which has circular recesses formed into its upper surface for receiving two rotary cutters, c c, which cutters are seated into the recesses so that they will not cut the insole of a boot or shoe while cutting off the ends of pegs. This cutter-stock A also serves as a guide while cutting off pegs and protects the upper leather against inj ury. B represents a flanged head, which is hollow, and screwed onto the upper end of a tubular standard 0, which standard is constructed with a flanged base, 0, having holes through it for receiving screws that secure the standard rigidly to a bench or table. To the head B I pivot, at a, the cutter-stock A, which can thus be adjusted at different angles with respect to a horizontal plane. This adjustment may be made by means of a rod, E, which is represented in the drawing, Fig. 1, as being pivoted to the cutter-stock at i, and connected to the standard G by means of a pin, it, which enters one or the other of two holes made through the lower end of said rod. I may continue the rod E down through the bench on which the Standard is secured and connect it to'a treadle,

. so that the angular movements of the cutter-stock A can be regulated by the foot of an attendant. Inside of the standard 0 is a rod, D, on the upper end of which is keyed a pinion spur-wheel, g, and on the lower end of which is keyed a belt-wheel, d. Motion may thus be communicated to the rod D by any convenient prime motor. The toothed pinion g is more or less spherical, and it engages with the teeth of a pinion, s, which is fastened to the hub of a spur-wheel, 0, and with this spurwheel rotates around a bolt, 0 that is made fast into the cutter-stock A, as shown in Figs. 2 and 3. To the spur-wheel 0 a circular flangeplate, 7', and a circular cutter, c, are fastened by rivets, or otherwise, and rotate around the bolt 0? with the spur-wheels s 0. The spurwheel 0 engages with a spur wheel 0 to which another circular cutter c is secured that revolves with its spur-wheel around a fixed bolt, 0 The cutter-last named has an annular groove, 0", between it and the wheel 0, into which groove the outer portion of the flange-plate r is received, as shown in Figs. 2, 3, and 4. I This flange-plate 9" will cover up the teeth of the wheel 0 and prevent the teeth of the spur-wheels from clogging with pieces of pegs which get into the space necessarilyleft around the cutter which is secured to wheel 0. The faces of the two cutters c c are. made up of radial cutting edges, which are inclined from the heads of their bolts to their circumference. These cutting edges are flush with the heads of bolts 0 c and also with the surfaces which surround or inclose them, so thatthe insole-leather will not be injured in the act of cutting off the ends of pegs in boots and shoes. The cutter-stock A is constructed with serrated faces 0 e at its its ends, for the purpose of cutting out the ends of metallic pegs or nails at the toes and heels of boots and shoes. By having the cutting edges of each cutter arranged around a bolt-head and exposing such head, as shown, itwill afiord a support for the instrument upon the insole of a boot or shoe and preventliability of cutting the leather. It will be seen that the two cutters rotate in opposite directions, the efi'ect of which is that portions of the ends of pegs which are broken down, but not out off clean by one cutter, will be out ofl" by the succeeding cutter, whose teeth rotate in an opposite direction to those of the preceding cutter.

If desirable the rear cutter may be omitted, and the space which it occupies covered with a serrated plate but I prefer to employ two or more cutters.

I will state that I do not claim a single rotary cutter unless the same shall have combined with it the guard r for preventing the cuttings of pegs falling down between the gears.

It will be seen that in the act of'cutting out pegs from boots and shoes, any desired amount of pressure may be made on the cutters without their wearing away the bolts, for the reason that the spuravheels to which the cutters are fastened have bearings all around upon the bottoms of their respective recesses in the cutter-stock.

Having described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. Two rotary peg-cutters, revolving and cutting in opposite directions, applied to a cutter-stock, substantially as and for the purpose set forth.

2. The flanged guard 1' applied beneath one of the cutters and working in a groove which is beneath the other cutter, for the purpose described.

3. The cutters c and their spur-wheels recessed into the sole of the stock A, flush with the edges thereof, and also flush with the heads of the bolts 0 0 substantially as described.

. 4. The fixed serrated cutter 6, combined with the rotary cutter c and stock A, substantially as and for the purposes described.
