IMPROVEMENT -IN PEGGlNG-MACHINES.

Specification forming part of Letters Patent No. 180,020, dated July 18, 1876; application filed March 16, 1876.

, To alt/whom t may concern:

Be 1t known that I, ALPHEUs G. GALLA-Y HUE, of Morrisania, in the city, county, and State of New York, have invented certain new and useful Improvements in Machines lfor Pegging Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the. saine, reference beinghad to the accompanying drawing, which forms part of this specification.

Tins invention, like-other previous inventions of mine, more particularly relates to machines adapted to effect or perform the whole of the work thatl relates to the pegging of boots vand shoes, including the making of the .holes in the shoe to receive the pegs, and the driving of the pegs in the holes; also the cutting ofthe pegs from the strip; likewise ajack, having throw to it, and being capable of universal mot-ion, together with a feeding-wheel or device for adjusting the boot or shoe to provide for the regular insertion of the pegs in a .row or rows at suitable distances apart; and a gage for directing the edge of the sole.

The inventlon consists in certain novel com binations of part-s involving a peculiar construction of the jack or boot and shoe supporter, whereby not only provision is made for turning or otherwise operating the jack to peg all around the sole of the boot or shoe, and to tip the latter as required, but whereby the boot or shoe may be tipped alike from either Vside or end by the operator without changing l 111s position, and so that in the tipping of it into pegs; and, furthermore, the invention includes a combination of devices whereby one and the same cam is made to operate both the feeder of thel strip from whichthe pegs are cut and the lipped connecting-rod which actuates the awl and hammer.

xm, looking toward the rear, and Fig. 4 a horizout-al section, in part, on the line g/ y. Fig. 5 is a face view of a cam and roller arm for actuating the peg-cutting knife and shoc- Y feeder.

A is the upright frame portion of the machine, and B its revolving main shaft, from which the several automatic movements are derived. The awl b, which is projected at regular periods through the sole for reception of the pegs, is attached to a v ertical slide, C, which is moved up and down by a wrist-pin, c, on acam, D, fast on the shaft B, by or through the intervention of a connecting rod orbar, E. This rod or bar is formed with a hook or lip, d, at its lower end, so that said hooked bar, when rising, catches, as shown in Fig. 3, on a stud, e, attached to the slide G, which carries the hammer f and lifts 'said hammer till the hooked connectingrod E arrives at the eX- treme vof its pstroke, as in Figs. l and 2, when the hook or lip (l ofsaid rod passes from under the stude, anda spring, y, acts on the slide G to drive down thehammer with a spring-pressure on the peg, the hammer being arranged to one side ofthe awl b to secure its timely action on the peg inserted in the hole last made by the awl, and the shoe, in the meantime being'fed to bring the hole with' peg in it under the hammer. Thus the hooked cowiecting-bar E operates both the awl and hammer.

The strip of wood to be cut up into pegs may be taken from a roll, as usual, and is introduced along orover the table H from back to front, and between feed-rollers I I', into and through a groove-guide, k, through the front end of which it is projected intermittently by the feed, and cut up into pegs, one at a time, by the successive actions, in timely relation with the feed, of a knife, J, each successive feed of the strip driving out a cut peg into a face-plate, K, formed internally with a peg'-A guiding surface in line with the hammer, which, as well as the awl, works throughsaid face-plate. As the cnt peg is thus expelled by the feed of the strip, the latter is by such act projected forward in front of the guide k, to have a fresh peg cnt from it in the succeeding cuttingstroke ot' the knife, which latter and the awl, hammer, and the wood and shoe feeding devices` are all arranged to operate 1n proper relation with each other to insure the automatic performance of the work.

It is an advantage, however, to sinlplify the pegging mechanism as much as possible, and l not only make the same rod E operate, as hcreinbel'ore described, both the awl and hammer, but also cause the cam D, which actuates, by its wrist-pin c, the rod E, to likewise actu ate `the positive-driven roller I of the strip feeding rollers l I' by means ot' a lever, L, with attached pawl Z, which works in a ratchet, m, on the roller I. This lever L is actuated by the peripherieally-toothed cam D as against a spring, n, which gives a return motion to the lever, and keeps it in contact with the cam. i

Furthermore, I make one and the same lever and a single cam actuate both the knife J, which cuts the striprup into pegs, and the intermittently-rotating feed-wheel M, which automatically feeds the shoe and its last, as car ried by the jack under the awl and hammer. Thus the knife J is attached to a projection, o, on a lever, N, which is fast on the forward end of a rock,-shaft, P, said lever also carry- 1 ing a feed-pawl, fr, which works in a ratchet,

s, on thc-back of the feed-wheel M. This lever N is worked to and fro, to give to the knife J `and pawl Ir their required forward and backward movements, by means of an arm, Q, fast i on the back end of the rock-shaft l?, and carrying a roller, t, which tits within a facegrooved cam, lt, on the main sha-ft B.

S is the roller-gage, which serves to direct the edge ot' the shoe-sole, or against which the edge ot' the sole bears. This gage is adjust able in or ont, to vary the distance of the pegs from the edge ofthe sole.

A' is a weighted treadle, on which thcjack is supported, and by which the shoe-sole is borne up against the feed-wheel M, and when the foot is applied to the treadle thc pressure ot' the shoe on the wheel is regulated or removed.

Thejack which carries the last B', with the shoe on it, by means of toe and heel rests C' D', is constructed, in part, ofa swinging stock, l

having a base-socket, E', which receives up within it a pin or stem, F', which admits of the `rotation of the jack around it, and from which the jack maybe lifted and removed, when required. This stem F is freely inserted r. or pivoted within a cup or socket, G', pivoted at s' to the treadle, in such manner as to allowof the jack having a universal movement in :its jointed connection with the treadle, apart from its rotation around the stem F'.

The toe-rest C' is made adjustable longitud inally, and the heel-rest D' is formed of a lever, pivoted at a! to a bar, H', of the jack, and

provided with a pawl, b', which bites into aratchet, c', attached to said bar. This construction provides for the lifting of the shoe and itslast from the pivot a' as a center ot' motion, and for the setting and holding ot' the toe ofthe shoe down on the rest C.

The swinging stock ot' the jack or boot and shoe holder is composed, in part, of a frame, J', having the socket E' rigidly attached to or forming a portion of it. The bar H1, which carries the toe and heel rests, is pendent through an attached `arm or bracket, H2, by an upper pivot, d', on 'the frame J' of the swinging stock.

Attached to the back ofthe frame J1, by upper and lower pivots c1 c2, are two levers, K1 K2, in slotted connection above and below by pins f1f2, at suitable distances from the pivots or centers c1 c2 of the levers, with the bracket H2 of the bar 1211.` These com,- pound levers extend to opposite sides of the jack, and are provided with handles at their outer ends for the purpose of enabling the operator not only to swing the whole jack, as required, including the turning of it around the stem Il", but also for the purpose of allowing the operator, without changing his po sition from either side, to tip the shoe alike from either side, by rocking either lever K1 K2 on its center c1 or c2, to adjust the shank ot' the shoe, or other depressed or irregular portion of its sole, so that the. pegs will be entered straight, as required. Such adjustment has been provided for in other jacks, but not in the same manner, or by compound levers from each side; and by the `pivoted connection, as described, of the bracket Vlil2 ofthe bar H1, and the levers K1 K2 with the frame G' of the stock, and the connection of the le vers at f 1]'2 with the bracket H2, the tipping of the shoe by either lever K1 K2 causes the shoe to have little or no forward or backward motion; or, in other wordsto Work froma fixed center at the contact of the shoe with the feed-wheel. This prevents any acceleration or retardation of the feed when the shoe is being tipped, and, consequently, insures the pegs being inserted at regular distances apart.

Then it is not required to tip the shoe by the independent rocking ot' either lever K K1, but simply to rotate or swing the jack to peg around the shoe, (commencing. at the heel,) then the levers K K1 are locked or united together, and restrained from rocking -on their centers c1 e2 by means of a locking-bar, M', which may be arranged' on the pivot e2 ot' the lever K2 outside ot' said lever, and running in direction of the length of the latter outside of it, and extending throughout the lengthot' the jack, so that said bar may be manipula-ted from either side ot' the jack, or outer ends of the levers K1 K2, to lock or unlock said levers as required.

The bar M' locks the levers together by the fitting of its one outer end, 1I', in a recess, 7c', in the handle end of the lever K1 by the action of a spring, m', tending to tip or tilt the bar M sidewise on the pivot e2, which it tits loosely for the purpose. The spring m then holds the bar M/ in lock at its end t" with the lever K1. The other end ot' the bar i is free to slide sidewse on a pin, u', connecting Vsaid bar willi the lever K2.

Suitable handles or projections may be provided at either end ot the bar M', to enable the operator, by the pressure ot' lthe hand or lin ger, to liberate the end i of the locking-bar, against the action of the spring m', from the locking-notch kin the leverKl.v Fig.2ot` the drawing shows the locking-bar M as released.

I claim- I 4 l. The combination, with the swinging stock or boot and shoe holder E J and its pendent toe and heel rests C D, of the compound levers KI K2, arranged for operation substantially as specied, whereby the boot or shoe may be similarly tipped from opposite sides or ends of the jack without accelerating or retarding the feed of the jack and its boot 01 shoe.

2. The locking-bar M', in combination with the compound levers K1 K2 ot' the jack, essentially as and for the purposes herein set forth.

3.- The connecting-rod E, formed with a hook or lip, D,in combination with the awl and hammer slides C and G, therevolving Wrist-pin c, and the lifting pin or stud c of the slide G, substantially as specified.

4. The combination, with the lever N, of the attached pawl i, which operates the shoefeeder M, and the attached knife J, which divides the strip into pegs, essentially as described.

5. rlhe cam D, with its attached wrist-pin c, in combination with the hook or lip formed connecting-rod E, the lever L, with its attached pawl l, and strip-feeding roller I, substantially as and t'or the purposes herein set forth.
