POWER PEGGlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 262,952, dated *August 22, 1882.

Application filed January 9, 1882.

To all whom it may concern:

Be it known that we, GEORGE HARWOOD JACKSON, residing at Natick, in Norfolk county,

and CHARLES HENRY INMAN, of Stoneham, in Middlesex county, in the State of Massach usetts, and both citizens of the United States,

have invented certain new and useful Improvements in Power Pegging-Machines; and we hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

These improvements are based upon a class of machines heretofore generally in use for pegging the outsole of a boot or shoe to the 2 upper, in which the boot or shoe is supported upon the top of ajack whose standard is swiveledat bottom to aweighted foot-lever or pedal, by means of which the boot or shoe is held up to the feeding and pegging devices, the jack being susceptible of universal freedom of motion upon its support, in order that thepoint of union of the boot-solewvith the bearing-plate or foot of the pegging mechanism, may, for the moment of driving a peg, constitute the center of motion of the work, and in order, also, that the, surface of the sole at the point being operated upon may be brought to a horizontal plane, both of which movements are req- .uisite to the successful operation of the main such head, while the traverses of the awlbar are efiected by a cam-groove in such wheel actuating a stud from such bar. The pegdriver plays within a throat in a stationary ver- (No model.)

tical guide located at the front or delivery end of the peg-wood channel, while the awl re mains and operates outside of such guide. The sole of the boot or shoe is held by the weighted lever against a roughened bearing or foot secured immovably. to the machine-head and located immediately in rear of the guide of the peg-driver, such bearing-plate or foot constituting the center of motion of the work, and serving to prevent feeding motions of the boot while the awl is out of the sole. The combined movements of the oscillating head and awlbar are such that the awl first retreats a distance equal to the space separatingit from-the driver, descends, and buries itself in the sole, and then, while in such sole, advances and,in conjunction with the lowerend of its bar, (which at this time bears upon and lowers the sole from the hold of the foot before named,) feeds the boot an equal distance in the opposite direction, then rises out of the sole, (its bar at the same time rising and freeing the sole, and permitting the weight of the lever to restore such sole to its bearing against the stop,) and again retreats in readiness to again descend and punch a new hole in the sole, the peg-driver, during the descent of the awl, also descending and driving a peg into the hole punched by the preceding descent of the awl. With the advance of the driver and awl the knife secured to the machine-standard operates to sever a pegyfrom the peg-wood strip, while simultaneous] y with each retreat movement of the awl and driver over the sole the peg-wood strip is fed a distance equal to the thickness of a peg, in order to present a peg to the driver at each reciprocation of the latter. The peg-strip is advanced by rotary feed-wheels embracing its opposite sides, and intermittently rotated by suitable mechanism to effect step by step the feeding movement of the strip, this strip, practically endless, being fed by such wheels into and through a channel intercepted by the stationary knife carried by the standard, by which knife the 'pegs are severed in succession from the strip and are pushed forward successively beneath the driver by the advance of the pegstrip from behind.

i In our machine we retain the elements going to make up the structure of the machine ICO as above organized and generally in use,vand, so far as the drivers and. awls are concerned, which operate independently of each other, though moving simultaneous]y,we merely duplicate them by adding extra ones, which ad dition (being but a matter of degree and an addition to the capacity of the machine)'we do not claim as possessing any patentable' novelty.

Our presentinvention consists mainly in the following improvements: first, in a pegging machine having a movablejack, the combination of animmovablebearer roughened to hold' the shoe, a vertically-reciprocating barcarny- .ing multiple awls and peg-drivers, and feeding mechanism for the pegs, substantially as hereinafter set forth; second, the combination of a reciprocating bar, provided with awls-,'pegdrivers, andja knife, with feeding mechanism for the pegs, siibstantially as set forth, anda bearer which is roughened to hold the shoein place; third, in combination with a bearer roughened as described, a vertically-reciprocating bar provided with awls and'drivers and arranged to force the shoe away from saidbearer-as said awl descends; fourth, an oscillating plate orhead, in combination with a bar which is guided thereby, a shaft which oscillates said plate and reciprocat'es said bar, awls and peg-drivers carried by said bar, and a holder below said bar, substantially'as set forth; fifth, the combination of an oscillating plate, a reciprocating bar, adriving-shaft, a knife carried by said bar, parallel guides for peg-wood, and feeding devices for the same, substantially as described, the'g'uides'or channels for the peg-wood being of variable depth; sixth, adjustable cap-plates for the delivery channels or guides for peg-wood, in combination with said channels, a reciprocating bar carrying a cutter, feed-wheels andratchet for advancingthe peg-wood, and'the driving-shaft,

substantially as set forth also in divers other improvements hereinafter more particularly described, and pointed out in the claims.

The drawings accompanying this-specification'represent, in Figure 1, a front elevation, in Fig. 2 a verticalcross-section, andin Fig. 3 a verticaland longitudinal'section, of a peg ging-machine containing our improvements.

Fig. 4 is an under side view of the pegging g has been made is shown atj as a horn or spur devices. Figs. 5,6, 7, and 8 are detailedsee tionsof the pegging devices. Figs. 9 and 10 are views of the cap-plates of peg-troughs.

In-these drawings we have not shown the upright standard which supports the peg driving mechanism, nor thejack which supports the boot or shoe while being pegged by these devices, as these devices, as well as theentire machine in general, are the same assingle-peg ging'machines generally in use, it being-sufficient to say that the said standard is'of 'such a height as to support the peg-driving'mechr anism in a plane levelwith the operators'eye', the superstructure of the machine containing such mechanism being secured to thetop of this standard. The jack, which is of the constructionusedin power pegging-machines now maintain the sole of the boot or shoe in con- .tactwiththe bearing-plate or foot of the machine while the sole is being pegged to the upper, and also in such manner that thejack issusceptible of freedom of motion in various directions upon its support to properly present the face of the sole to the action of the awls andrdrivers.

The superstructure of the machine consists of ahead-stock, G, of proper form and strength,

carrying at top a horizontal shaft, H, provided with apulley, I, while the front end of this shaft, outside. of the front face, J, of the headstock, carries an eccentric cream, a, which enters a vertical groove formed in the rear part of a vertical plate, K, or between antifriction rollers 11 b, pivoted to the rear side of such head, this head being pivoted at about its-centerhy ahorizontal pivot or trunnion d to the'front face, J before named, and being free to oscillate inv short arcs of a circle upon such pivot by the rotations of the cam a. The oscillating" head K is grooved or otherwise providedfwith vertical ways or guides e eupon its frontface, to receive and guide the movements'of a vertical bar, f, such bar being impelled in vertical reciprocations within the headby. a'spur, g, from its rear side entering a cam-groove, h, in the front face of a'disk'or wheel secured to the front end of the shaft H in rear of the cam a, the parts being so vtimed or'adjusted that as the lower end of the plate K' swings to the right'(the observer facing the front of the machine) and comes to a stop the awl barfdescends and buries the awls in the work, as well as drives the pegs,

the plate remaining-stationary in this position w'hile'this'takes place; but as soon as the awls'and'd'rivers'have descended, as stated,

the head swings to the left to the extent of separation-oftwo pegs ofa line, carrying the awlsand'dri'vers with it, and comes to a stop, 'andremains in this position while the awls and drivers are being elevated.

The bearing-plate or foot to which allusion roughened upon its under side and formed .uponthe outer end of a horizontal bar, l, se-

the said head. The bearing-plate or foot j is 10- cated immediately'below the oscillating plate 'K, and serves asabeari-ng and center of motion to t'he'work.

In carryingourimprovements into practice we proceed'a's follows:

' To the lower end of the awl-bar f we secure,

as shown in the presentinstance, two awls,o0,' and two peg-drivers, a a, the former being in IIO 'be driven, while the distance between; an aw-l and a driver uponone side and the samejupon the opposite side determinesthe extentof space between the two rows of pegs. The two'driv ers n at play within vertical grooves or throats p p,formed in a vertical guide, q, disposedim: mediately in front of the bearerj, such guide constituting part of a plate, 8, secured to the lower front part of the swing-plate K. Immediately in rear of the guide (1 the plate 8, has a horizontal ledge, t, in which horizontalchanr nels u o are created, these channels connecting respectively with the vertical grooves pp, and extending rearward to and converging into a single channel, to, created in the rearpart of the head K, the partition 00 separating the two channels, a v, vanishing at a knife-edge, and preferably falling awayat an angle of fortyfive degrees, or thereabout, to a horizontal plane. I i

The knife for severing the pegs (to which allusion has been made) is shown at 3 (see Fig. 5) as a flat vertical blade confined, by a clampscrew within the slotted and rear end of a curved arm or stock, z, the front end of which is secured to the a-wlbarf above, the awls, this knife in its descent intercepting thechannel w. and extending practically to the bottom of the latter, andin its passage severing aupeg from each of the peg-wood strips. The strips of peg-wood are in the present instance two in number, and of unequal width, and are shown at e b. They enter the common channel w and traverse the latter as one until they reach the separator x, whenthey are separated by the latter and diverted by it in the i'ormof two independent lines of pegs intothe. separate channels a c, which they traverse until they enter the vertical channelspp in the guide q, being reduced to pegs by the action of the knife before bein g separated.

The mechanism for feeding the peg-strips is the same as that hcretofore in use, and consists as follows: 7 H

c d represent twin rolls, roughened on their peripheries and disposed uponopposite sides of the two peg-strips, the roll 0 being pivoted within a pocketin the lower rear part of.- the head K, before mentioned, or a bracket orextension, e, of such head, while the opposite and outerroll,d,isjournaled within boxesff,

contained within an orifice, 9, formed in a boss, h, secured to or making part of the bracket 0, the outer roll, cl, being crowded toward the inner one by a spring, i, acting upon the boxesff. Q

. To the lower end of the shaft of each roll 0 d is affixed a spur-gear, j or k, which engageeafch other,,while tof the under side of the mace gear, j, is secured a ratchet wheel, l, whichengages a spring-impelled pawl, m, piviotedtotherunder side of the main head G, in rear of-thebearerj. l i A s thepawl m is pivoted to an immovable 4 support. and the ratchet follows the move.- n ents of the oscillating plate K, it will be seen that with each vibrationof this head the ratchet 7 5 will be ad vanced to theextentof oneof its teeth. Hence thelength of each of these teeth is such as to advance the peg-strip a distance equal t the width-0t a peg.

To prevent vertical slipping and misplace- 8o mentof the peg-strips we place over each channelac a cap-plate, a oro, the platen covering the channel a and the plate 0 covering the channel 17, and the plates being separated bya partition, 10, of erw ualthickness with the partition m,( seeFi g. 8,) and, like the latter, vanishing to a knife-edge immediately in front of the; knife to aid in separating the peg-strips. Each cap-plate a 0 is continued rearward into 7 l a flatplate, q or r, theinnerplate, q, abut: o ting against and being supported by the outer faceof the bracket 6, while the plate 1" abuts against the, plate. q, and both are secured to thebracket by a common clamp-screw, s, which passes; through a vertical slot, t or u,in1 each 5 plate, the two slots t u coinciding, and being to enable eachplate to beraised or lowered however, oneprimary channel, as shown, for

the reason that by feeding the two peg-strips together as one they are less liable to slip than if they were separated and one feed-wheel were until the bottom of its sole rests against the bearerj at the point in the edge of such sole at which the rows of pegs are to begin, itbeing.understoodqthat the lower end. of the oscillating plateK is swung to its extreme positionto theleft, and the aWl-bar stands at its highest position'within such plate. The belt beingshipped to the fast pulleyl and the mal chine thereby put in motion, the plate K swings to-the.right, thereby carrying the dual awls (as well as peg-drivers) a step backward, while at the same time the pawlm acts upon the x 0 ratchet l .to rotate the gears j k! and feedwheels 0 d and advance the peg-strips and 4o 1 sdeposit thepegs of one row opposite the spaces the line of pegs in advance of them adistance equal to the thickness of a peg, thereby pushing the two outermost or advance pegs into the throatsp p to a point directly beneath the drivers. The head K remains immovable until the awls descend and bury themselves in the sole. The drivers drive the two advance pegs into the holes punched by the last preeeding'descent ot' the awls, and the lower end of the awl-barfimpinges upon and lowers the boot, and frees the sole from the restraintof the bearerj at the same time that the knife descends, severs a peg from the end of each strip, and rises when the plate K swings at bottom to the left or forward, and advances the boot the distance required to separate any two pegs of the same row. The awl-bar and awls, with the-drivers and knife, now rise, and the bearerj again takes hold of and prevents any forward movement of the sole, and the head K retreats, as at first, thereby bringing the drivers in line with the holes last punched and pushing forward the advanced pegs of the two lines to a point beneath these drivers, this feeding of the pegs being effected by thepegstrips from behind pushed forward by the feedrolls, as before stated. These movements are repeated with rapidity until the desired portion of the sole has been gone over and two rows of pegs driven, when the operator raises the weighted end of the lever, allows thejack and bootto drop, and removes the boot just pegged.

By'the employment of dual sets of drivers,

and awls and two peg-strips we are enabled to drive two rows of pegs in the-time now required to drive one, and these two rows must of necessity be parallel. By arranging the drivers and awls in parallel planes obliquely to the path of movement of the plate K we between the pegs of the other row, thereby preventing, as before stated, weakening or fracture of the sole, and at the same time presenting a neat appearance.

By delivering the rows of pegs to the drivers in independent channels we are enabled to greatly simplify the construction of the punching and driving mechanism, as we have merely to duplicate the awls and drivers. By adapting the channels which contain the multiple-rows of pegs to be varied in depth we are enabled to drive pegs of uniform lengths or of varying lengths at pleasure.

One object we have had in view in devising this machine is to render a power pegging-machine readily transformable from a single to a double machine, or vice versa. This we are enabled to do by simply adding or removing an awl, peg-driver, and peg-strip and substituting a single plate for the strip removed. This plate may be added in the place of the plate 0", in which case it will be of similar shape, but having a pendent lip to extend between the boss h and the peg-strip a and filling the portion of the channel w occupied by to and meeting the separator x,- or the pendent 'lip may be an independent plate to be secured in place, allowing the plate 1" to remain.

Having thus described our improvements and the operation and advantages of the same, we claim as our invention, and desire to secure by Letters Patent of the United States, the following:

1. In a pegging-machine having a movable jack, the combination of an immovable bearer roughened to hold the shoe, a vertically reciprocating bar carrying multiple awls and pegdrivers. and feeding mechanism for the pegs, substantially as set forth. 1

2. The combination of a reciprocating ba provided with awls, peg-drivers, and a knife, with feeding mechanism for the pegs, substantially as set forth, and a bearer which is roughened to hold the shoe in place.

3. In combination with a bearer, roughened as described, a vertical] y-reci procati n g bar provided with awls and drivers and arranged to force the shoe away from said bearer as said bar descends.

4. An oscillating plate or head, in combination with a bar which is guided thereby, a shaft which oscillates said plate and reciprocates said bar, awls and peg-drivers carried by said bar, and a holder below said bar, substantially as set forth.

5. The combination of an oscillating plate, a reciprocating bar, a driving -shaft, a knife carried by said bar, parallel guides for pegwood, and feeding devices for the same, substantially as described, the guides or channels for the peg-wood being of variable depth.

6. Adjustable cap-plates for the delivery channels or guides for peg-wood, in combination with said channels, a reciprocating bar carrying a cutter, feed-wheels, and ratchet for advancing the peg-wood and the driving-shaft, substantially as set forth. 7
