PEGGlNG-IVIACHINE.

SPECIFICATON forming part of Letters Patent No. 269,840, dated January 2, 1883.

Application filed July 15, 1882.

To all whom it may concern:

Be it known that I', ANDREW EPPLER, Jr., of Quincy, in the county Norfolk and State of Massachusetts, haveinvented certain Improvements in Pegging or Tacking Machines, of

which the following is a specification. This invention has for its object to provide a pegging-machine adapted to drive pegs into the sole of a boot or shoe which is held in the io hands of the operator instead ot' beingjacked.

The machine isintended for use in temporarily securing the outer sole by pegs preparatory to the permanent attachment of the outer sole by stitching or nailing. 1 c The invention consists, as a whole, in a peggingmachine composed ot' a lxed frame havingl a tubular projection through which the pegs are driven into the sole, a frame or head carrying the driver and awl bars pivoted to 2o fixed frame, so that when oscillated on its l pivot the driver and awl are caused to coincide alternately with the fixed tubular pro jection, and mechanism f'or operating said driver and awl bars and for oscillating; the pivoted frame, and peg-wood holding and feeding mechanism, all combined and operating as described hereinafter.

The invention also consists in certain details, allot' which I will now proceed to describe and claim.

Ot' the accompanying drawings, forming a part ot' this specification, Figure 1 represents a front end elevation ot' a pegging-machine embodying niyinvention. Fig.2 represents a side elevation of the same. Figs. 3 and 4 represent respectively sections on lines m x and 1/ y, Fig. 2. Fig. 5 represents a section on line z z, Figs. l and 2. Fig. 6 represents an enlarged section on line xrr', Fig. 2. Fig. 7 represents a similar section, showing the pivoted frame with the awl and driver in a dif-terent position. Fig. 8 represents a horizontal sec tion on line y y', Fig. 7.

The saine letters ot' reference indicate the same parts in all the figures.

In the drawings, A represents the fixed frame of' my improved machine, said frame having a suitable base, 2, bearings 3 3 for the driving-shaft B, and a downwardly-projecting 5o arm having a tubular projection or nose, 4,

(No model.)

against the lower end of which the outer sole ofa boot or shoe is 4held by the operator, and into which the awl E and driver Dare alternately forced, as described hereinafter, the nose being adapted to enter the usual channely formed in the outer sole.

C represents the frame or head which con tains the driver-bar l) and awl-bar E. The frame C is pivotally connected by 'a bolt, F, with a socketed boss, 5, on the xed frame A, 6o and is capable of' oscillating in a vertical plane on said bolt or pivot. The driver-bar D has an offset, D2. which bears on a cam, G, on the driving-shaft, and is raised by said cam. A spring, H, forces the driver-bar downwardly, when the bar is released by'said cam. The awl-bar E has a similar oltset, E2, and is operated similarly tothe driver-bar by a cam, l, on the driving-shaft and a sl'iring, J, the offset E2 resting on the cam I, as shown in Fig. 3. 7o

K represents a lever, which ispivoted to ears L l., formedon the xed frame A, and has at one end a friction-roller bearing against a cam,

N, on the driving-shaft, and at the other end an adjustable screw, K', bearing against one 75 side ottheI pivoted head or frame C. A spring,

M, attached to the fixed frame A and bearing at its free end against the opposite side ofthe frame C, holds said frame with ayielding pressure against one end ot' the lever K, thereby 8: pressing the opposite end ot' the lever K against the cam N. lt will be seen therefore that when the driving-shaft B is rotated the awl and the driver bars will be reci procated longitudinally by the cams G I and springs H J, and the frame C will be oscillated on its pivot by the cam N, lever K, and spring M. The oscillating movements ofthe frame G are of' such length that they cause the awl E and dr.iver- D to coincide alternately with the oritice in 9o the nose et of the fixed frame.

The peg-strip P, which furnishes the pegs driven by the machine, is held in a holder, C. which is rigidly attached to the lower end of' thei'rame U, and is provided with a vertical 95 orifice, R, (seen in Fig. 7,) in which thedriver reciprocates, and with a guid e-chan nel for guiding the inner end of the peg-strip into said orifice. The holder C is provided with a suitable t'eed-.roll, against which the peg-strip is roo pressed by a spring, T. The arbor U of said l E. is

feed-roll is provided with a ratchet, V.

l represents a pawl, pivoted to the fixed frameA and engaging with the ratchet. Vhen the pivoted frame G is moved iu the direction indicated by the arrow in Fig S the ratchet is moved therewith against the pawl XV and rotated one step, thus causing the feed-roll to move the peg-strip P forward in the holder.

The peg cutting or scoring knife a is attached to the driver-baranddescends through a suitable recess formed to receive it in the holder C.

'lhe operation is as follows: A lasted boot or shoe, with the outer sole laid upon it, is held by the operator with the sole in contact with the nose 4. The pivoted frame or head C, being at the extreme of its movement, (shown in Fig. 7,) the awl E' is forced down through the nose 4 and makes a perforation in the outer sole and the parts of the boot or shoe on which said sole is laid. The downward movement ofthe awl, under theimpulse ot the spring J, is so quick that the operator is enabled easily to prevent the boot or shoe from yielding te the pressure of the awl. This could not be so readily done if the awl were driven downwardly by a cam. The awl is then raised and the frame C is moved by the mechanism that cscillates it in the direction indicated by the arrow in Fig. S, causing the driver to coincide with the oritice in the nose 4, this movement feeding the peg-strip, as above desciibed, and moving the partially-severed peg at the end of the slrip into the oritice R. rlhe driver is now foi ced downwardly by its spring, as shown in Fig. 6, forcing a peginto thehole formed by the awl. The driver then rises, the frame U is moved to the position shown in Fig. 7, and the operation is repeated. rlhe operator is thus enabled to cause any part of the sole to receive a peg, and the operation of temporarily securing the sole is very quickly performed without removing the boot or shoe from the last on which it was made. The awl preferably tapered inwardly on all sides toward its lower end and there left slightly blunt, as shown in Figs. 6 and 7, instead of being brought to a point, as usual. This form is best calculated to adapt the awl to penetrate the leather, and at the same time relieve it from liability of injury by contact with the bottom of the last within the boot or shoe.

It will be observed by reference to Fig. 1 that the point where the frame (l is pivoted to the tixed frame is at the opposite side of the driving-shaft B from the point where the lever K is pivoted. By this arrangement of said pivoted points the jar of the machine is reduced to lthe minimum.

I claim- 1. 1u a peggingmachine for temporily attaching outer soles, the combination of afixed frame having a tubular nose or peg tube adapted to enter t he channel of an unattached outer sole, an oscillatingl iframe or head pivoted to the tixed l'rame, awl and driver bars reciprocated in the ocillating fraaie and alternately entering the nose of the tixed frame, and peg wood holding, feeding, and cutting mechanism secured to and actuated by the oscillations of the frame to supply pegs to the tixed nose, substantially as described.

2. 'lhe combination, with the lixed frame having the pawl W, the oscillating frame having the awl and driver bars, the peg-strip holder attached to the oscillating frame, and the feeding-arbor U, journaled in the holder, and provided with the ratchet V, engaged with the pawl W, and rotated by said pawl during `the movement in one direction ofthe oscillating frame, as set forth.

ln testimony whereof I have signed my name to this speciiication, in the presence of two subscribing witnesses, this 10th day of July, 1882.
