lMF RO VE-MENT IN PE GGlNG-MACHINEQ FOR BOOTS AND SHOES. I

Specification forming part of Letters Patent No. 173,428, dated February 15, 1876; application filed January 21, 1876. I

To all whom it may concern I Be it'knownthat we, BENJAMIN F. Srnnr- EVANT and JOHN E. ,BIGKFORD, of 'Boston,

cap resting on, and pivoting in, the horn-tip,- and combine with said cap mechanism which holds the cap from rotating with the horn as it is turned under, and with reference to, the pegging mechanism, to admit of continuing the pegging operation around the toe and heel.

This combination is needed because the awl descends in the center line of the cap, and then moves forward a distance equal to the distance apart of the centers of the pegs; hence, in the cap' must be made a slot for the traverse of the awl-point projecting through the leather, and this slot must be maintained in the path of the feeding movement of the awl. Moreover, if the peg-points protruding through the leather are not cut on the said slot mustbe continued to and through the periphery of the cap, to let the peg-points pass as the work is fed over the cap on the horn end.

In the drawing which forms part of this specification, the peggingmachine head shown is one well known to the public as the Varney Pegger, which, having been" patented, will not be described or referred to otherwise herein than incidentally.

The arrangement for raising andlowering the horn shown in the drawing is identical with what is shown in an application by us now pending before thePatent Office, and,-

hence, will not be herein described.

Figure 1 of the drawing is aside elevation of a pegging-machine provided with a rotatin g horn embodying our invention. Fig. 2 is a front view. of the' same. Figs. 3, 4, and 5 are plans of the cap on the horn end variously modified; and Fig. 6 is a central verticalsection taken through the cap.

The cap a is made with a pivot orshaft, which, at b, fits in a vertical bearing madeuin the horn end, the part c receivingthe bevelgear 11, which is nearly, or quite, contained in, and protected by, the horn end. The inclined arm e and the horizontal arm f of the horn are fitted to receive and retain in proper bearings the'inclined'and horizontal shafts, (shown in dotted lines, Fig. 2,) while concentric with the axis of rotation of the horn there is fixed a vertical shaft, (also shown in dotted lines,) which does not rotate; and on said shafts-are fixed bevel-gears, meshing into each other, as shown, the meshing pairs having the same number of teeth, and the gear 9 on the upper end of the inclined shaftmeshing into the gear at on the cap-shaft, gears g and (1 having the same numberof teeth.

By the eonnection,through gears and shafts,

as shown and described, of the cap a with the fixed gear on the vertical shaft, it will be obvious that the cap will be held from rotation with the horn, and that the slot cut in the cap for reception of the awl-point and pe -points, and for the traverse movement of said points, willremain, practically, fixed with reference to the direction of the feed movement given to the sole.

In Figs. 3, 4, and 5 the cap is shown as surmounted with movable plates of steel, designed to operate as cutters, which are interchangeable for others as they become worn, dulled, or broken. v

In Fig. 6 the central opening is shown as elongated into a radial slot, which slot isadjusted, through adjustments of the gearing described, so as to be in line with the feed movementgiven to the sole.

The cutter shown in Fig. 3 would crease and weaken the peg-points as, by the feed given to the sole, they passed between the converging blades, so that, by action of a peg-float or hand peg-cutter, they would break off smooth with the inner surface of the inner sole.

In Fig. 5 the cutter is like that shown in Fig. 3.)

Fig. 3, except, only, that its cutting-edges are serrated, and by it the peg ends are creased, so that they can be easily broken ofl.

Fig. 4 shows a cutter by which the peg ends are cut or broken entirely ofl' in the act of feeding the work along on the horn.

If it is not desirable to out or weaken the projecting peg ends, then the cutter-plate can be taken off, and the driven peg ends will project into, and will pass out of, the slot or channel cut in the cap a. (Seen'in dotted lines in With the Varney pegger-head the peg-hole is made in one location, and the peg is driven in another; but with some forms of peggerheads the awl and peg-d river act in the same line by offset or lateral movements of both, in which case a surface-feed is used. v

With our invention herein shown any known practical form of pegger-head having the following instrumentalities may be used: a surface for resisting the upward thrust, an edgegage, an awl and peg-driver, and mechanism for properly operating them, a peg-feeder, and a cutter of pegs from pegstrips, and mechanism f'or properly operating them, and a mechanism for feeding the soles over the horn end.

We claim' 1. The combination, with the horn of a pegging-machine, of the slotted or grooved cap, held against the rotation of the horn by means substantially as described.

2. The combination, with the feeding device for moving the shoe, ot' a stationary cutter, attached to the horn, and against which the ends of the pegs are borne and out as the shoe is being pegged, substantially as described.

3. A pegging-machine horn having at top a slotted passage for the reception of the awl and peg, and out of which the pegs pass by the feed movement of the shoe, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
