HAND PE GGING-IVIACHINE Specification forming part of Letters Patent No. 33,022, dated August 6, 1861; Reissue No. 2,447,

. dated January 8, 1867.

To all whom 'it may concern:

Be it known that I, EDGAR M. STEVENS, of Medford, in the county of Middlesex and State of Massachusetts, have invented certain improvements in Hand-Machines for Pegging Boots and Shoes, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, making a part of this specification, of which- Figure 1 is a longitudinal section includ-- ing the peg trough and with the awl descend-- ing. Fig. 2 is a like view including only part of the peg trough, and with the awl ascending. Fig. 3 is a horizontal section of the peg-trough seen from above.

I am aware that automatic feeding points have been before used in hand peggers, by TW. lV. Batchelder, and Charles Keniston; but in each case these points have beenl distinct instruments, separate from the awl and driver or plunger. l am also aware that peg wood strips have been fed to the driver before now.

My invention has for its object rst making the awl and peg driver in two pieces, and so uniting them to a plunger as that while both rise and descend together, one of them shall have a lateral motion independent of the other, for the purpose of feeding the machine to the work. Second the contrivance for feeding the pegwood forward continuously by the action of the plunger or peg driver as the holes are made.

rlhe following is a description of the machine.

A. A.. is the handle body of the machine made cylindrical and hollow, and having a cap a. a. screwed on to the top of it.

B. B. is the plunger which passes through the cap and has its head surmounted with leather at l, to receive the force of the blow of the hammer.

3. 3. is a band of rubber under the head of the plunger to aid in the first retraction of the awl after the blow is struck.

is a small cani projection on the rear lower end of the plunger for operating the feed of the pegwood. rThe plunger is driven up after the blow by the spiral spring l. l. 1. l. encircling it, in the cavity of the handle. This spring is conned between the cap, and a shoulder or ring 0. 0. in the lower partof the cavity.

C. C. is the awl holder pivoted to the plunger at 7, and having a small notch or shoulder near its lower end at c.

D. is a small pawl or dog pivoted in the handle body at 8. and having a small spring Z to prevent its being thrown too far out, and to aid in driving it downward and inward so that its lowermost inner corner shall take into and against the shoulder c of the awl holder, after it has passed down and forceit back in its ascent the distance of a space between the holes.

5 is the descending point of the awl. It ascends at 6.

E. is the peg driver attached to the plunger. e is the peg tube.

F is a set screw for regulating the swing or throw of the awl, and the spaces between the holes.

j is a spring for throwing and keeping the awl holder' forward against F and in the line of its descent, when it is released from the action of D.

DG. G is the peg trough, and g g the strip or peg wood.

H. H. is a forked rod supported in bearings at L. 7L. and driven backward by the cam on the plunger, and forward by the spiral spring 2. 2. 2. 2, and is for feeding forward the peg wood by means of the small pawl l, pivoted in H. H. with its spring z' pressing .its point down upon the pegwood g. Under certain circumstances toothed wheels with springs as at J. y' (Fig. 3) may be used in place of pawls and springs as at 1*. z', but l prefer the latter device in both places and J.

K is a small stationary knife blade for cutting olf the pegs one by one as the peg wood is fed forward, and the peg driven by the driver.

K is a spring against the bottom of the peg trough to keep the wood from falling.

L is a pointed bent spring, pointing forward and resting against the peg wood on the opposite side from l, to prevent any retraction of the pegwood.

9. 9. are guides against the edge of the leather, which may be made adjustable.

The mode of operation of the machine is as follows: On striking a blow with a hammer upon the head of the plunger, the awl descends in a perpendicular line out from the body of the machine into the leather at the point 5. As it retracts by the force of the rubber band 3, and the spiral spring l, the lower corner of the pawl D engages in the notch e of the avvl holder, and the awl is thrown or crowded back, or rather the machine is thrown forward, so that the awl rises out of the leather and into the Ymachine at G, by that time advanced to where 5. had been. That is as soon as the awl has descended into the leather and retracts, the point 6. in the machine, moves forward to the position before held by the point 5. the latter point being advanced the same distance during the retraction of the awl in the leather, the instrument being thus advanced or fed, along one space atatime. The awl being freed from the controlling pressure of the dog D. when it again descends will enter the leather at the place to which the point 5. has advanced being the length of the space between the holes. ln this manner the machine is moved or fed along upon the material by thel action of the awl without the intervention or use of any separate centering or other point. As the plunger is driven down the small cam b driven against the forked rod H. forces it back the width of a single peg. As H passes back the pawl I. slides back over the pegwood, which is prevented from any retraction by theforward pressure ofthe point of the spring L. As soon as the cam 6*. has acted upon H. and returned, the spiral spring 2. drives H forward again, when the point of the pawl I. presses against and into the pegwood and feeds it along a peg at a time into the peg tube e,

direction, and on the next advance of the rod this wheel isheld stationary by the spring j and its Ateeth engaging with the pegwood feed it along as required. The throw of the awl, and consequently the feeding of the machine, and the spacing of lthe distances between the pegs, may be regulated by the set screw F.

' Diii'erent devices may be used for varying the position of the awl, and feeding the Ina-- chine thereby by means of cams and springs but I prefer the one described.

wWhat I claim as my invention in hand pegging machines and desire to secure by Letters Patent isl. Making the awl and peg driver in two pieces, and so uniting them to a plunger, as that while both rise and descend together, one of them shall have a lateral motion independent of the other, for the purpose of feeding the machine to the work, substantiallyl as described.

2. The device I. or its equivalent in cornbination with the plunger, and rod H, for feeding the pegs forward as they are driven.
