SPECIFIG.A TION- 'ro ALL wHoM Ir MAY ooNenRN;

Be it known that WALTER FITZGERALD, of Boston, in the county of Suffolk, and State of Mhssachusetts, have inventedy an ,improvement in Pegg-ing Machines, and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suilicient to enable those skilled in the art to practise it.

The improvements relate particularly to thatclass of pegging machines in which the jack, or mechanism which supports the hoot or shoe to be pegged, has a direct feed movement imparted to it, to bringlthe slioe'intc position for the successive actions of the awl and peg-driver, in contradistinction to those machines in'which the shoe is fedlhy giving to the awl a lateral movement while in the shoe, or by the contact and lateral movement of a feed `foot connected with the head The invention consists in supporting the last, and the gearing by which. it is fed, upon a frame or jack capable of rocking movement, both in a transverse and longitudinal direction, so as to enable the edge of the shoe being pegged to be brought at all times .into proper position with respect to the awl and peg-driver. Also in the construction and arrangement oi' the cutting mechanism, which splits the pegs in succession from the end of the peg wood.

The drawings represent so much of the mechanism or" a pegging machine of the class referred to, as will enable my improvements embodied thereupon to he readily understood, A showing a 'ront, and B a side elevation of the same; C a horizontal section taken through the peg-cutting mechanisi a denotes the last, mounted on a long, ,sliding gear plate b, into the teeth of which a pinion c meshes; the rotation of this pinion effected in any suitable manner, imparting intermittent movement to the plate b, to carry the whole length of the edge of the shoe around, under, and to the action of the awl and peg-driver, which are placed in and operate from the h'ead j in the usual manner, and which, they form no part of this invention, are not shown in the drawings. This plate b slides upon another or bed-plate e, mounted on astandard or vertical platcf, which rests and rocks upon the top ,of a standard g, (in the direction of the arrows seen at A while the standard g is hung on pins ZL, and so that it may rock in the opposite direction or transversely. The movement of the platefis eil'ected by a pirriou z', meshing into a segmental rack k, on the bottom of the plate, the shaft upon which the pinion is Exc-d extending through the plate, and having a knob Z, by turning which the movement ot' the rack is effected. The standard g is hung loosely on the pins L, and is swung into position loy application of the hand to the knob Z. By turning the knob Zin either direction, and swinging the standard g in either direction, the anglo of presenta` tion oi the surface of the shoe being pegged may be changed during the progression of the shoe, in accordance with the constantly varying curvature of the surface of the sole, heel, shank, and toe of the shoe. The strip of peg Wood is seen at m, and it is fed through, the head j, and to the peg-tube n, in the usual manner. This peg-tube make in a face plate o, and the tube is open towards theadjacent face of the head as seen at'C. On one side of this tube is a cutter p, iixed to the plate, its cutting edge forming Kone corner of the tube, and abutting against the surface ot' the head. The peg-wood passage through the head opens into this tube, and upon the opposite side from the cutter p, is a bed cutter g, fixed to the 'face of the hea-dj. The peg wood is `fed forward into the tube as seen at C, and then the faceplate has a sliding movement given to it in the direction of' the arrow. This causes the cutting edge oflthe cutter o to actiagainst the wood, and shear oii the peg against the bed cutter g. This action severs each peg while in the tube, and the continued lateral movement of the tube carries the peg directly under the peg-driver. Consequently cach peg is cutwhen and only when it is to be driven, in contradistinction to cutting them at a distance bach from the pcg-tube, and having a series of cut pegs feeding forward, an arrangement that often causes the pegs to become obstructed in their Y in such tube, i

In the operation of the machinethe movements are as follows: An awl tirst descends from the head and pierces the hole 'for the peg. As the awl asccnds the plato 0 moves laterally, (the end of the pcg wood being in ssage to the tube or the peg-tube which lateral movement carries the cutter lo through the peg wood, severing the peg, which moves on in the tube until said ttrbe comes under the peg-driver and over the hole just made by the awl, the driver then descending and forcing the peg into the awl-hole. Then the driver asccnds, the plate moves back, during which movementv the feed of the shoe is effected by the gear mechanism below, when the successive movements above described repeated, until the shoe ispegged; the shoe as it is fed being tipped longitudinally and transversely, as may berequired to cause the pegs to be properly inserted as above set forth.

I claim, in combination with the gear-platte b, upon which the last is mounted, and through which the feed of the shoe is e`ected, the mechanism which admits of both longitudinal and transverse rocking movement of the' shoe, substantially as set forth. v

I also claim, in combination with the peg-tube n, in the face-plate o, the cutter p, placed in the face-plate,

with its cutting edge disposed as shown, so that the lateral movement of the plate Bevers the end of the peg wood in the tube from the strip to form the peg, substantially as described.
