SOLE-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,254, dated April 19, 1881.

Application filed June 2, 1880. (No model.)

Be it known that'I, ALBION KNowL'roN, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Sole-Nailin g Machine, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, making a part hereof.

Swin gin g-head pegging-machines have been widely used for many years for pegging boots and shoes with wood pegs cut from a strip of peg-wood, and the main object of my invention is to adapt these machines for driving wire fastenings instead of wooden pegs; and my invention consists, mainly, in the combination of a mechanism for feeding the wire, and a mechanism for cutting off the wire fastenin gs and presenting them properly to the driver with a swinging head carrying the driver-bar and shoe-feed.

In the drawings, Figure l is a side eleva-, tion of the upper part of one of these peggingmachines with my appliances in place of those for holding, feeding, and cutting the pegwood. Fig. 2 is a front view; Fig. 3, the same with the face-plate removed. Fig. 4 is a perspective enlarged,showing the principal changes to adapt the machine for driving pegs of wire instead of pegs cut from a strip of peg-wood. Figs. 5, 6, 7, and 8 are details showing the principal parts in the altered machine.

The parts marked with numerals are all in the machine, and therefore need no description.

The parts new with me are plate A, the cutter B, its spring C, the throat and cutter-carrier D, the wire-guide tube F, and the wirefeed mechanism.

The plate A is firmly fastened to the swinging-head 6, and carries a stud upon which the cutterB is journaled. The spring C (see Figs. 1 and 8) acts to keep the cutter B against its stop b, the hole I)? through the front end of the cutter being in line with the hole (I through the throat and'cutter-carrier D when the front end of B is against its stop I), so that the wire fed down through the guide-tube F will pass into the hole 11 in B. The throat and cutter-carrier D is also secured to the swinging head 6,

the driver entering the hole 01 and passing through the hole 1 when driving the peg. The guide-tube F is secured to the face-plate 7, which is fast to the swinging head 6, and arranged so that it opens into the hole 61 of the throat and cutter-carrier D. The wire-feed wheels f f are also secured to the face-plate 7. One of them, f, is provided with a ratchet, which is worked by a spring-pawl carried by the radius-barf and this bar is actuated by the slide f which slides in ways f attached to the face-plate. This slide is actuated by the small cam f attached to the main cam 4 of the machine.

The operation is as follows: In Fig. 2 of the drawings the swinging head is shown in its position just after the shoe has been fed. The driver is raised by the main cam 4, and the slidef? is raised by the passage of its cam f under thewristf. Its upwardmotion raises the radius-barf, which is suitably connected with slide f and through the spring-pawl and ratchet turns the feed-wheelf, the throw of the feed'wheel f depending upon the extent of motion of slide), the length of wire pegs being regulated at will by the eccentric-stop f which acts as astop to slide f as clearlyshown in Fig.2, the pegs being longest when slide f is allowed to descend as low as the eccentric f will permit. A spring, f, is used to depress slide f The wire is fed down through tube F through hole d into the hole Z1 As the swinging head swings back the friction-roll b on cutter B is borne against the frame of the machine, and the hole 1) thereby carried under hole 6?, cutting off a Wire peg and carrying it under hole d and the driver. The driver and awl then descend and the head swings forward again to feed the shoe.

By the use of my devices this class of machines are converted at small expense into wirepeg-driving machines.

I have shown only those parts of the peggin g-machiue necessary for the full understanding of the parts devised by me. The parts not shown are well understood by all skilled in the art. I

What I claim as my invention is 1. In combination with the swinging head 6, the cutter B, operated to cut and carry the wire peg by the motion of the swinging head, substantially as described.

2. The mechanism for feeding the wire, consisting of feed-slide f radius-barf wire-feed wheels f f andfeed-adj ustin g stopf", arran ged and combined'together as described, whereby the length of wire fed can be varied by increas ing or diminishing the downward motion of the feed-slide by means of stop f 3. The combination of cutter B, the throat and cutter-carrier D, guide-tube F, and wirefeed mechanism with the driver 9 and swinghead 6 of the pegging-machine, substantially as described.
