. IMPRovi-:MENT IN MACHINES FOR PEGGiNG BooTs AND SHOES.

specificafion forming pm of Letters-Patent No. 40,806, amen October 18, 1863.

To all whom it may concern Be it known that I, J. HAMILTON BROWN, 'of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements-in Machines for Pegging Boots and Shoes, of which the`following is a full, clear, and exact description, reference being had to the accompanying dra-wings, making part of this specification, in which Figure 1 is a view of the plunger, together with the awl and peg-driver,detached from the case, the spring` which raises the plunger being removed; Flg. 2, a view of the knife which splits off the pegs, together with its rod; Fig. 3, a detached view of the inner end .of the pegtrough, one side of the trough being removed to show the parts within Eig.

4, a View of the side of the peg-trough, de-

tached from Fig. 3; Fig. 5, a View, and Fig. 6 a plan, of the case, as seen from below.

My improvements are particularly applicable to the machine for which Letters Patent of the United States were granted to S. S. Bucklin, assignee of Moses Marshall, on the V5th day of November, 1861, and` only those parts oflthe machine will now be referred to which are necessary to au `understanding of my present invention.

In this machine as heretofore constructed the knife-rod was first attached to the plunger, which was then passed down through the opening in the case, the knife itself being necessarily attached to the rod,afterthe1atter was in place, by a screw or pin but the machine, whenv in use, was so Violently jarred by the blows of the hammer that the knife, when thus 'attached, was exceedingly liable to be loosened 5 andto obviate this difficulty and enable me to secure= the knife and its rod firmly together, or to make them in one piece, is the object of the first part of my invention, which I will nolwiproceed to desoribe.

The plunger,"with its snrrounding sleeve A, is insertedinto the top of the case, to which it is secured by screws passing down through the cap B. The knife is attached to a block, 0,- whioh is secured to a cylindrical rod,D, as seen in Fig. 2; the 'knit`e, knife-block, and rod being made in .a single piece, or permanently seeured together, so that they cannot be jarred apart by use. .The rod D and block O are bored out in the center 'for the accommodation of the spring f, and a slot, g, cut entirely through the rod, extends from a point,

1, about the center of the rod, to near the top of the rod at 2. Upon one side of the rod this slot communicates with a shorter slot, h, that extends 'through to' thetop of therod. The spring f is supportedatits lower end by a pin, 1/. (Seen in Fig. 6.) '-From the exterior of the sleeve A projects a flattened pin, k, that works in the slot g above''t-he springf; and thus, as the plunger is operated, the pin k in its descent bears upon the spring f for the purpose of depressing the knife, and upon the shoulder 2 as it rises lfor the purposc of raisingtheknfetosnlit-off the pegs.A

rl`he knife anditsrod, when thus constructed, are introduced into the machine as follows: The plunger is depressed to its lowest point, and the rod is'iuserted at the hole m in such position that the pin 7a shall enter at the slot h.. The knife-rod is then raised until the pin strikes against the. shoulder 3, and it is then turned until the pin is brought into the long' slot g, in which position it may be forced up into .the machine, the fiat portion d of the knife-block rest'ing against the corresponding portion, b, of the case, and thus the knife is held in position.

To take out the knife,it is simply necessary to reverse theoperation ofinsertingit-that is, while the plunger is at its lowest point, to withdraw the rod until the shoulder 2 strikes against the pin k. This'will relieve'the surface d of the kni'fe-block from the fiat portion b of the case, so that the knife--rod may be turned to bring the pin k into the slot h,when the knife may be withdrawn. I am thus enabled to make the knife and its rod of a single piece of metal, by which the difficulty before alluded is avoided.

In the machines as heretofore constructed the pin-k descended to the bottom of the slot g, to insure the'descent of the knife beneath' the lower edge of the peg-strip, and the consequence was that the bottom of the knifeblock bruised and disfigured the surface of the sole. To remedy'this inconvenience without limiting the range 'of the knife, I have elongatcd the slot g so that the pin kcan never strike the shoulder 1 at its lower extremity, and I employ a spring, f, of sufficient strength 'to insure the descent of the knife each time 'to deface or bruise its surface.

In the machines as heretofore .made the strip of peg-wood rested'upon. the hottom of the trough, and had a follower above it to keep it in place, and in order that the width of the trough might correspond at all times withzthe width of the peg strips, the follower was made adjustable. It.is necessary, however, that the follower, or whatever it may be that supports the top of the peg-strip, should extend. out to the very end of the strip in order to support the pegs while they are being' split ofi. I

It is obvious that :ne knife can never rise above the top 'of vthe peg-strip, as it would otherwise interfere with the support above it but it is quite important that the knife'should always rise to the top of the strip, as otherwise the. top of the peg would still adher'e-l to the strip, while its point was forced over beneath the driver, and the latter, when it descended, would strike the peg upon its side and' inash it up, instead of driving it point, foremost, into the awl-hole. i Ii', now, with a perv ranged as above indieated, the knife be adiuste'd so as to split off a short peg when a wider peg-strip is introduced, the knife will ,notpenetrate it, and the pegs will not be entirely separated from the strip; and if the knife be adj usted to properly split off a long peg, when a norrower peg'strip is introduced, the knife. will interfere with the follower.A To remcdy this difficulty, Icause the peg-,strip to rest beneath the top of the peg-trongh, up against which it is held by a spring, so that the knife, being adjusted to penetrate just to I the top of the strip, will always split off the peg and force it beneath the driver, whatever may be the width of the strip.

Fig. 3pis a viewiof the inner end of my improved 'peg-trou'gh, one side of the trough being removed to show `the parts within, the

side thus removed being seen in Fig. 4, The

upper wall, fr, of the trough is made permanent,

and 'extends over the entire length of the v -trough and follower arstrip, which is kept in contact with' it by a spring, .9, secured to the' fioor of the trough.

The peg-strip is fed up against the driver by a sprin;Lr-finger,` n, attached to a rod, T, Fig. 4, which-is forced .forward by the spring w. The rod T is forced back each time the plunger rises by an incline upon the knifeblock, in a well-known. manner. Any other 'suitable method may be employed for feeding' in the'pe-g-stripo The knife may now be fixed permanently to its rod, so as to come up just beneath the upper wall of the peg-trough,

of peg that can be used in the machine.

Heretofore the. gage, which, by bcaring distance of the pegs from the ed ge, requiredto as, for instance, when passing from the inn'er t`o the outer row of pegs. 'To economize the time which this adjustment required, I make distances from the awl, so' that by simply into action the pegs will be placed at l,theproper distance from the edge. This complex gage H is seen in Fig. 6. On loosening the confinbring either of the faces 4 or 5 into action, in which positionit is confined'by again tightthan trwo faces, if required.

VWhat I elaim as my invention, and desire to secure byInetters Patent, is i I 1. The method, herein substantially described, of uniting and securing'the knife-rod to the plunger, whereby the knife and its rod may he made in a single piece, for'the' purpose set forth.
