JOSEPH SARGENT, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO ELMER TOWNSEND, OF SAME PLACE.

PEGGlNG-MACHINE.

Specification forming part of Letters Patent No. ddflhfl, dated October 11, 1864.

To all whom it may concern:

Be it known that I, JOSEPH F. SARGENT, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Pegging-Machine; and I do hereby declare that the following,- taken in connection with the drawings which accompany and form part of this specification isa description of my in vcntion sufficient to enable those skilled in the art to practice it.

Recent applications have been made by ine for patents for certain improvements in awlfeed pegging-machines, such improvements relating mostly to the manner of driving the and and peg-driver, of simultaneously cutting and pointing the pegs, and of some other novel features con tained'iu what is called the head of the machine, or that part'embracin g the peg-feeding, awl-feeding, and peg-driving mechanism.

My present improvement relates, principally, to the disposition and manner of operating the jack with the shoe placed thereupon, it consisting in sc arranging the jack'that it can be rolled laterally on its support to enablethe shoe at all times or at all portions thereof while being fed to be properly presented to. the awland peg-driver, and also in automatically producing'this desirable lateral change of position of the shoe; and the improvement also embraces the mechanism for producing the transfer of contact, the manner of cutting. the pegs from the peg-wood strip, the employment of a brake to prevent rotation of the driving-wheel in the wrong direction, and the method of producing the stop of the awl and peg-driver bars at the foot of the same instead ofat the top thereof; also, in the construction of the toe or throat piece to feed-in channeled soles. I

- Figure 1 of the drawings represents a front elevation of a pegging-mach ine embodyin g my improvements. Fig. 2 is aside elevation of the same. The other figures represent views of, the head of the machine and details thereof, with some modifications of parts of the invention, and those views will. be more particularly referred to as'I proceed to escribe the mechauism to which they relate.

in denotes the post of the machine, erected upon :rimso-plnto and supporting the head 7),

which carries the pegging mechanism. A treadle or foot-lever, c, is hung in a tubular hearing within the foot of this post a; such bearing being supported upon a pin, d, so that the treadle tips vertically by the pin rhwhile it rocks or turns laterally in its bearing, the bearing and pin making together a universal joint. To the front part of this treadle a vertical rod or rocker standard, e, is jointed, and upon the top of this standard a bent lever, f, is hung, this lever f carrying on its upper end the jack or jack mechanism g, which supports and holds in position the shoe h, the jack being so applied to the lever as to freely turn therein, in order to allow the shoe to be fed by the awl around its entire edge. The standard e and lever. f hold the jack in such position (by the counter-balance 2' on the treadle c) that the shoe is brought up into contact with the feeding and pegging mechanism, as will be readily understood.

The shoe is so mounted on the jack mechanism- (one part k of which turns on a pin, Z, relatively to the other part, m) that as the shoe is fed along by the awl in the direction of the length thereof the operator elevates or depresses the heel or toe of the shoe by the handle 11, so that as the shoe moves through the arc of a circle from the treadle c the surface being pegged can be raised or depressed as it is fed to present it perpendicularly to the movement or action of the awl 0. v This movement and the mechanism for producing it are not unlike those heretofore used. To peg the shoe to the best advantage, however, itis found to be necessary in pegging round or high-shank work to so mount the shoe that it.

can be rolled or turned laterally during its progressive movement by and to the action of the awl and .while it is being elevated or depressed by the operator, as set forth, and it is in this adaptation that the first part of my invention consists. 'loctfect such movement I joint the lever f to the standard e, making the standard a compound support for the jack, one part of which swings upon and relatively to the other and in a lateral direction to the shoe.

If the jack were immovable with respect to the standard e, (excepting by rotation thereupon, as in the common construction of pag ging-machines,) it will be seen that if the shoe is in. proper positionto peg at the point x, for instance, it cannot be so when the point y in the shank is'brought under the awl, on ac count of the greater lateral curvature of the shoe at the shank; but by hinging the jack with respect to the jack-standard the shoe can be turned laterally, so that at every point, as it is fed along, its edge can be kept at the same relative angle to the action of the awl laterally as well as longitudinally, no matter. what may be the lateral curvature of the surface of the shoe. This result is accomplished in the machine shown in Figs. 1 and 2 automatically, as follows: The lever fis jointed at its lower end to one arm of a bent lever, 10, turning on a fulcrum, q, in the standard 9, and having its otherarm jointed by a connectingrod, 7, to the post a, as seen. in Fig. 2. Supposing the shoe to be being pegged about the center of the sole or at the point as, the upper arm, 3, of the bent lever p and the lower arm of the lever f, or the centers qt u, will be in or nearly in a straight line. As the shoe is fed forward and the shank y'is being reached, the distance from the treadle to the surface being pegged becomes shorter and the tread'le and arm or standard a rise; but the inner end of the bent leverp is held from lifting by the connecting-rod -r, so that the upper arm, 8, of the bent lever is inclined inward, producing an inward inclination of the'lower arm of the lever f and an outward inclination of the jack, such inclination keeping the surface of the shoe properly inclined with respect to the awl and changing as the shoe progresses. As the heel or toe of the shoe is reached, the greatest distance between the surface being pegged and the treadle prevails, and the consequent depression of the treadle forces the adjacent 'ar'ms of the bent levers outward and brings the shoe-surface being pegged (which would otherwise have too great an inclination) back toward a horizontal position, and so on around the whole edge'of the shoe, the jointed levers bringing back the surface of the shoe'toward an inclined position laterally when the distance between the treadle and the surface being pegged is becoming shortened and the surface assuming too horizontal aposition,

and bringing back the surface to a more horizontal position when such distance isincreas ing and the surface has a tendency to be thereby too much inclined. Although I generally prefer this automatic system of mechanism, the jack may be turned to great advantage by a mechanism operatedby hand.

The automatic jack seen in Figs. 1 and2 is shown in detail in Figs. 3 and 4, which represent. respectively, side and end views of it. A jack to be turned laterally by hand is shown in Figs. 5 and .6, which denote side and end views of -it.

The frame r is hung upon a rocker-shaft, w,

which is j urna-led in the top piece, a, by

which the jack is supported on the treadlestandard. handle, b,projects up from the shaft w, and by this handle the frame and 61', and slot 6' holding the shoe from lateralmovement when desirable, and the handlen giving rocking movement to the shoe in the direction of its length, as in the other jack. A modification of this jack is shown in Figs. 7, 8, and 9. A rotating quill or cylinder is placed upon the post of the jack and is constructed with two segment-gears, a I), (see Fig. 8,) one of which, ad, is actuated by a segment-gear, 0 on the handle, while the other meshes into and rotates a similar gear, (Z on the frame 4.. Moving the "handle turns the gears a and I), while b turns the gear d and rocks the frame o and the shoe laterally, as will be readily understood.

The mechanism for fastening the shoe in position on the jack is substantially like that heretofore employed, consisting of a pin, f, (see Figs. 3 and 4,) which enters the heel of the last and forces the shoe up on the rest 9 by an arm, 71', said arm being fastened into a ratchet, 71,. In Fig. 5 the arm h has a springpawl jointed to it, and by pressing the thumb against the lower end of the pawl,'bearing it toward the arm h, the pawl is released from the ratchet and the arm' at the same time moved on its center pin.

The levers f p, to regulate the lateral inclination of the shoe, may be so jointed together asto variably determine the amount of such inclination, so as to change the same for boots and shoes having different degrees of curvature in their soles and shanks.

The swing-plate k, in which the awl andpeg-driver bars operate, is hung upon the front plate, Z, of the head of the machine. This swing-piece is seen not only in Figs. 1 and 2, but also in Fig. 10, which shows a vertical section of the head through the driving shaft, and in Fig. 11, which is a front view of. the swing-piece, with its face-plate and awl and peg driver bar removed.

Fig. 12 shows the face-plate and driver-bar in elevation, and Fig. 13 the same in vertical section. Fig. 14 is a rear elevation of the head.

The upper end of the head has a vertical slot, m, as seen in Figs. 10,11, and 14, through which a'pin, p projecting from the top of the swing-plate It, extends. The plate 70' swings upon or from this pin as a center, the elongation of the slot permitting the necessary ver- .tical movement to the swing-plate to produce, in connection with its lateral movement, the

transfer of contact of the shoe from the testpiece or retainer 0 to the throat-piece p", and in connection with the awl the feed of the shoe, such vertical movement being also imparted to the peg-box, which is fixed to and moves with the swingplate, giving in connec tion with the lateral movement of the pegbox a drawing stroke or action to the peg- Wood against the stationary knife, which severs the peg from the strip. The vertical and lateral movement of the swing-piece is produced by an eccentric, q, on the drivingshaft a", such eccentric working in the rear face of the swing-piece, the motions of which corre spond to the motions of the eccentric. The peg-box s is attached to the hack of the swingpiece, the pe -channel leading into the pe tube in the throat or toe piece 1), through which the awl and peg-driver work. This toe or throat piece is fixed on the swing-plate. When the awl and peg-driver descend, the throat piece is in juxtaposition with the stationary retainer 0. The upward motion of the awl and peg-driver bar u is produced by a wiper or cam, w, fixed on the front end oft-he driving-shaft, such cam operating against a friction-roll, y, on the bar v to lift it, while the downward movement or throw of the bar and its peg-driver and awl are pro duc'ed by a spring, 2, as will be readily understood. Just before the awl descends thefeed-surface of the. throat-piece p is above the line of the holding or bot-tom surface of the stationary or retainer piece 0. Simultaneously with the downward throw of the bar the eccentric carries the swing-piece below the line of the retainer, pressing the shoe down beyond and out of contact with the retainer. The shoe is then fed forward by the awl and toe or throat piece 11, and the toepiece does not rise sufliciently to bring the shoe againinto contact with the retainer 0 until the awl has been raised-or nearly raised out of the shoe. It will be observed that the downward spring movement of the bar it is arrested at the bottom of the bar by the shelf (1- such shelf and, if necessary, the bottom of the bar being provided with a leather seat to lessen the concussion. Where spring-awl and driver bars have been heretofore employed, their downward mot-ion has been arrested at the top of the bar by a projection from the bar coming in to contact with. some part of the plate in which it runs. This is objectionable, because the projections from the bars are very liable to break, and because the concussion produced by the blow injures and disarranges the mechanism. By receiving the blow at the foot of the bar and near to the shoe this concussion is mostly prevented, besides which, when the awl-bar is driven down, the toepiecep' has just carried the shoe away from the retainer, so that the force of the blow is mostly received directly upon the shoe and is not imparted to the head or frame of the machine. With this construction I combine an adjusting-screw, n, by which I am enabled to regulate. the force of the blow as circumstances inav require, as will be readily understood. This screw works through the top of the swing-piece, its lower end abutting against the spring or a washer placed thereon.

The stationary pegknife is seen at Z) in Fig. 1- and in Fig. 15, which is a reversed plan of the machine enlarged. As the peg-box is moved laterally toward it, bringing the pegstrip into contact with it, the strip also re ceives an upward movement by the eccentric,

thus giving a drawing action to the knife in cutting off the peg. lVhere a stationary knife has been before used, the wood is only moved laterally against it, and where a movable knife is employed it is only moved laterally against the strip; but here the movement of the eccentric combines a lateral and vertical movement, and the peg is cut off more advantageously than when the contact is only lateral.

The fly-wheel c is made with a depression or stop, (Z (see Fig. 16, which is a cross-section of the wheel,) and a brake, e is hung loosely upon the head I), as seen in Fig. ll, this brake having a foot, f projecting from one side of it, the bottom of which is provided with a friction pad or leather, g As the wheel turns in the direction of the arrow, the brake-bar turns on its pin and allows the wheel to slip over it; but if the wheel be turned in the oppositedirection its tendency to move the brake-bar causes the foot to impinge tightly against the surface d and prevents the wheel from turning in the direction opposite to that indicated by the arrow. This is very useful in a treadle-machine like that shown in the drawings, because the action of the treadle is constantly liable to turn the wheel in'the wrong direction.

At A in the drawings is shown a.front view of the toe or peg, throat and feed piece 12' in their relative position at the downward throw of the awl.

At B an end view shows the adaptation of the throat to enter and feed in a channeled sole, the throat-piece being made narrow for this purpose.

\Vhere a vibrating or rotating surface, in contradistinction to apointed instrument like the awl, has been used in pegging-machines, such surface has only been made to work upon the top of the shoe in the plane of the top surface thereof. In pegging channeled soles-i. a, soles in which a channel is made in the top of the sole'in the line to be pegged, to the bottom of which the peg is driven, so that the sides of the channel or a flap turned up therefrom can be brought over the pegs when the shoe is finished to conceal the pcgssuch a feed is not practicable, and where the awl feed and retainer are used the retainer has been slotted, and the awl and throatpiece to which it'was attached or through which it and the peg driver worked have operated within this slot. \Vith such construction it is not practicable to peg in channels, because the throaepiece would either have-to work too far below the surface of the retainer and on one side of the slot, the retainer would rest upon the flap, leaving the other side out of contact with the shoe, or the re tainer and foot-piece being brought to-a stop on the surface of the shoe. the peg-driver would have to work below its plane, leaving the peg unsupported by the peg-tube wh le in the channel. To obviate these difficulties I dispense with the slotted construction of the retainer and make the throat-piece for the awl and peg-driver and the retainer of equal thickness, giving the vibrating and vertical that the bottom surfaces of both retainer and throat-piece act upon the bottom of the channel, the throatpiece descendingin close con tact with the retainer and feeding directly from its front side. i

C is a top view of the peg-box throat, showing the entrance of the box into the eg-tube.

D and E. show amodification in en and bottom view of the feed-throat piece. These views are enlarged from the main views in the drawings.

I claim- I p 1. In a peggingmaohinethe employment of a jack so constructed or mounted that it can turn or be turned laterally to hold the shoe properly to the action of the awl throughout its varying lateral curvature.

. 2. So organizing the jack with the levers or system of levers supporting it that the jackis turned automatically to bring the shoe laterally into position for the proper insertion of the awl and peg.
