PEG-CUTTER FOR HOR NS OF PEGGlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 703,951, dated July 1, 1902. Application filed January 6, 1902. Serial No. 88,693- (No model- To all whom it may concern:

Be it known that I, JOHN E. BICKFORD, of Whitman, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Peg-Gutters for Horns of Pegging-Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a device to be used in connection with the horn of a pegging-machine; and it consists in the peculiar construction and arrangement of the parts, which may be best understood by reference to the description and drawings.

The object is to make a compact and exact working device that will admit of a small tip to the horn. This object I attain by means of the mechanism shown in the accompanying drawings, in which Figure 1 is a view showing portions of the upper part of the standard of a pegging-machine, also the horn and parts of the working mechanism in elevation. Fig. 2 is a vertical section showing the upper end of the horn,

the cutting-knife, and a part of the knife-operating .bar. Fig. 3 is a horizontal section looking upward, taken on line 3 3 of Fig. 1. Fig; 4 is a vertical section taken on line 4 4 of Fig. 1. p

In the drawings I have shown the parts 0 a pegging-machine to which my peg-cutting device has a direct relation, all other parts being omitted. Parts of the standard are indicated in Fig. 1 byA and byA'. In the upper part A of the standard a part B of the main shaft of the machine is shown. This shaft has a beveled gear 0, which drives a corresponding gear 0 on the upright shaft D. To the lower end of the shaftD aspur-gear D is attached. This spur-gear D engages with the cylindrical gear D which in turn engages with the spur-gear D which rotates freely on the horn-shaft S and has upon its under side a cam projection cl, the use of which will be explained hereinafter.

The horn HH has a cylindrical base'I-I, which rotates freely on the horn-shaft S. The horn-shaft S has a vertical motion. of which the horn partakes, but it does not rotate. The said horn-shaft is forced upward by a weight or spring and is drawn down by a foot-lever. These parts are not shown, as they are of ordinary construction and well known. When the horn is drawn down for the purpose of putting on or taking off a shoe, the gear D moves with it, but is always in engagement with the cylindrical gear D The peg cutter or knife K (see Fig. 2) is made with a cutting edge at its upper end, which in coming in cutting contact with the peg moves forward and upward, cutting through the peg and at the same time working upward, pressing hard against and slightly into the surface of the leather of the sole of the shoe, the edge of the moving knife moving above the fixed knife h, as shown in Fig. 2. The knife 71 may be made asapart of the tip of the horn, or a flat steel platemay be fastened to the tip of the horn and the fixed knife-edge be made in it, and as the said plate wears it may be removed and repaired or a new one substituted for it. The lower end K of the knife terminates in a round'boss, which fits in a socket made in the upper end of the knife-operating bar K (See Figs. 1 and 2.) The upper end of the knife-operating bar has a slot in which a fixed pin K acts as a guide for the said bar. The lower end of the knifeoperating bar is pivoted to a lever K which swings on a fulcrum-pin at K and is operated bya rodL and spring L The upper end of the rod Lis provided with lock-nuts L L, which act as adjusting-nuts. The lower end of the rod L has a cross-arm L (see Fig. 4) attached to it.

At each end of the cross-arm an antifriction-roll L is placed. These antifrictionrolls rest upon the underside of the spur-gear D3 and as the said gear rotates turn on their axis without efiecting any movement of the rod L, except when the cam projections CZ on the underside of said gear come in contact with one of the rolls L. Then the roll will be forced downward, taking the cross-arm L and the rod L with it. This action will cause the lever K to throw upthe knife-operating bar Kfigiving motion to the knife K and cutting off the peg. By forming the hinged connection between the knife K and the knife-operating bar K by means of a boss and socket I avoid the use of weakparts and have aknife that is readily attached and detached.

I claim In a rotating-horn pegging-machine;a pegcutting knife adapted to move forward toward and over the edge of a stationary knife, name to this specification, in the presence of thereby pressing into the leather of the shoe, two subscribing witnesses, on this 3d day of 10 whereby the peg is sheared from the surface January, A. D. 1902.

of the said leatherand mechanism for oper- 5 ating said knife; a stationary knife adapted JOHN EJOKFORD' t0 coperate with the moving knife, substantially as and for the purpose set forth.

In testimony whereof I have signed my Witnesses:

FRANK G. PARKER, WILLIAM EDSON.
