To all whom it may concern.'

Be it known that l, Moses MARSHALL, of Lowell,l in the county ot' Middlesex and the State of Massachusetts, have` invented ccrtain Improvements in lllachines for legging Boots and Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, iu which- Figure 1 is a side view of my pegger, a portion of the case being removed to show the parts within; Fig. 2, a vertical section on the line .r of Fig. 3; Fig. 3, an underneath view of the same enlarged; Figs. 4, 5, and 6, details to be referred to hereinafter.

My present invention has for its object to perfect the application of an automatic feed to machines for peggin g boots and shoes; and itconsists in the employment of a feeding-point so arranged as to cuter the hole last made by the awl, (instead ot' making a new hole for the purpose,) and to feed the machine along the sole between each descent of the plunger.

To enable others skilled in the art to understand my invention, I will proceed to describe the manner in which I have carried it out.

The cylinder A is not materially unlike the body or casing of other machines of this class. The awl II is attached to a rod, F, which is secured to the bottom of the plunger B, and is of a size to adapt it to slide freely in a cylindrical passage, G, bored through the bottom of the casing. The peg-driver l, which is also attached to the plunger, descends through a suitable passage, c, which is open upon one side to admit the pegs from the peg-trough, as will presently be more fully described. The aw is driven into the leather and the pegs into the holes made by the awl by a blow of a hand-hammer upon the top of the plunger, and the awl is extracted from the leather by an india-rubber spring, W, immediately beneath the head of the plunger, which is compressed Letween the plate g on the head of the plunger and the cap-plate h of the casing 'by the blow of the hammer. The plunger is raised by a spira. spring, C, the upper end of which bears` on a ring, D, that-rests against the pin E, projecting from the plunger.

The motion of the machine along the edge 0f the sole for the purpose ol' spacing the dis` tances between the pegs is accomplished by the feedingpoint f, which is actuated by the following means: To the interior of one side ofthe body or case A is pivoted, ut. d, n lever, J,havingin its upper end an irregular slot, c, cutthrough it, ot' the form seen in the drawings. ln this slot works a pin, E, projecting from the plunger ll, so as to vibrate the lever J back and forth as the plunger rises and descends. The pin E also passes through a straight slot, m, in a division-plate, b, and thus the plunger is prevented from turning. To the bottom of the lever J is pivoted the feeding-pointf, which is attached to one end of the swivel-pin a, and is so actuated that on the rising of the plunger it shall first be thrust into the hole last made by the awl, and then by the continued upward motion of the plunger be fed along so as to bring the peg and peg-driver directly over the hole. 0n the descent of the plunger `the feeding'point is rst with-drawn from the hole, leaving it ready to be occupied by the peg, and is then carried back out of the way of the awl, which now descends to make a new hole, and on the plunger again rising the feeding-point enters this new hole and feeds the machine along. These motions are effected in the following manner: The feeding-point, as before stated, is secured to a. swivel-pin, a, which turns freely inthe bottom of the lever J. To the other end of this pin is secured a tooth, e, which engages with a notch in the lever L, pivoted to the lever J. j is a stationary' stop secured to the body of the machine, and i is a movable stop which is forced down by a spring, z, the oce of thc stops j and i being to hohl the lever L in position at certain times, while at others it is allowed to escape from their control.

The operation of this part of the meclian ism is as follows: When the plunger is up, Fig. 1, the end of the lever L has forced up the spring-stop i and is held stationary by the stopsj and i, the pointf remaining in the hole in the sole, immediately beneath the pegdrivel' and peg. As the plunger commences to descellll, Fig. 4, the motion of the pill E in llle curved portion of the slot l' vibrates the lever .l to one side. Whllc tllis is taking place the upper end of the lever L beinghelll stationary bythe stops l andj, this lever is vibrated, allll also thc pill ll; bllt as the tooth l' is held by the notch ill the lever L, alld is lnoved with it, the pill' fl is caused to turn, and thc feeding-point fis withdrawn tl'onl thc hole ill the sole, as seen ill Fig. 4. So soon as tllis has taken place, the lever L strikes against a pill, 2, on the lever J, b v whicll the lnotioll of the lever L upon its pivot is arrested alld its upper end slips past the springcatcll l', when, by the continued nlotioll ofthe lever J, tlle fccdinglpoint is carried back, Fig. 5, ont of thc way of the pegdriver allll awl, whleh are now, wllile the pill ll is descending through the vertical portion ol' its slot e, left free to descend for the pur pose of lnalling a llew hole alld of driving a peg illto the one previously made. As the plunger ascellds, it is necessary thatthe feeding-point go tllrollgll a dill'crent; set of motions, which are prodllced as follows: lllile 1 the pill ll is ascending through the vertical portion ofthe slot e the feeding-point lelnaills stationary, alld during the interval the awl has y risen clear ofthe path of tllis point. Tile pill E now enters the illclined portion of the slot e, alld the feeding-point begins to travel back, being still raised above and clear of the sul-face ot' thc leatller. 0n the feeding-point i arriving opposite to the hole last made by the awl, the upper end of the lever L strikes against the springstop i, Fig. 6, by which the point ll is forced down into the hole, and at thisjuncture the lever L strikes against a pill, 3, llpoll its opposite side, by which its ,l lnotiou on its pivot is arrested and the parts-E are caused to travel with the lever J, tllo l feeding-point causing the machine to nlove over the surface ot' the leather, wllile the up- 1 per end of the lever L pushes back the springil stop l', and the parts are again left ill the po- J sition seell ill Fig. 1.

M is the peg-trough, wllicll is attached to I the lower end ol' the cylinder A. The follower i N rests against the end of the pegstrip, alld is forced up for the purpose of feeding the pegs by a spiral spring, P, which ellcircles the roll 0 of thefollower. The peg-trough comnl unicates at its inner end with the passage c, ill which the peg-driver I works. Q is all elbow-lever which is pivoted to the cylinder. The lower arm of this lever, which is elevated by a spring, k, works through all opening in the top of the peg-trough, and bythe pressure ofthe linger may be caused to press upon the l pegstrip and stop the feed. Tile splitting' i knife l is stationary, and Vis placed inlnledil ately beneath the point where th'e opening in i the peg-trough conllnllnicates with the pasl sage c.

The gage R, by means of wllich the distance of the pegs from the edge ot' the sole is regulated, consists ofa. roller, ll, on the end of a bar, s, wllicll is adjusted in position by lncans of a screw, p, :llld spring t.

Operation: The pcg-trough M is supplied witll peg-strips A', (sllowll ill red,) which are lnade ill the llsllal way. The operator, holding the cylinder A witll his left hand, presses in the lever Q, by wllicll the feeding of the pegs is prevented. lle then strikes the head of the plunger allll discharges the peg wllich is already in the passage c. After this no more pegs will be cut ott' or driven until the lever Q is released. lle now places theI maclline upon the sole, the stop R resting upon the edge of the sole and regulating the distance to whicll the pegs shall be placed froln the edge. A blow is now given to the plunger by which the awl is driven illto the sole, froln which it is again extracted by the illdia-rllb ber spring lV. As the spring U continues to carry up the plunger, the feeding-point enters the hole just made by the awl, and then continues its motion, as already described, carryillg the machine with it a distance equal to the distance between two pegs. The lever (.2 is now released, and the pegstrip is forced forward illto the passage c by the spring P. It -will be seen on inspection of Fig. 2 that the nlaclline has heen so lnoved by the point f as to bring the hole last lnade by the awl immediately beneath the passage c. A second blow is now given to the plunger B, by which the pointfis first withdrawn froln the hole ill the sole alld retracted out of the way of the awl and peg-driver, the latter at the saule tillle pressing down the strip of peg-wood and splitting oil' a single pcg, the spring in the bottom of the peg-trough yielding to perlnit the peg strip to descend sufliciently for the purpose. As the plunger continues to de scend, the peg-driver forces the peg into the hole beneath it, and the awl enters the sole alld makes a new hole. These operatiolls are contilnled by successive blows ofthe halnlner upon the plunger until the pegging is completed. When it is required to lnake the holes simply, to be afterward filled with metallic nails, the feeding of the pegs is interrupted by pressllre upon the lever Q, as before explained.

f Among the advantages which the above lnethodot feeding possesses lnay be enumerated the following: First, the solo is not scratched or marred by the punctnres of the feeding-instrument; second, the feeding-point may be made stout and blunt, and will always engage sufficiently with the sole to insure the feed; tllird, the feed will always be uniform and without any liability to vary arising from the slipping of the feeding-point or its failure to engage with the solegfonrth, while the feeding-point is in the hole beneath the awldriver the instrument may be turned in any direction around this point without in the least aecting the relative position of the as to enter the hole previously made by the owl and move the machine along, foil the purpegs.

What I claim as my invention, and desire pose set forth.
