Specification forming part of Letters Patent No. 122,377, dated January 2, 1872.

. l To all persons to whom these prese-nts may come:

Be it known that I, LoUIs GoDDU, a citizen of the Dominion of Canada, but temporarily residing at Boston, of the county of Suffolk and State of Massachusetts, have made a new and useful Invention or Improvements in Machinery for N ailing Shoe-Soles or variousother articles with wire; and do hereby declare the same to be fully described in the following speciiication and represented in the 'accompalnying drawing, of which- `a nail-driver and its operative mechanism, a

mechanism for feeding in the wire from which each nail is to be severed, a mechanism for receiving the wire and transferring the nail portion thereof to the guide-nose passage, and,

finally, a mechanism for severing a nail from the wire. a

The special object for which the present machine is designed is the fixing of soles or welts in place by a few nails preparatory to their being regularly pegged or nailed to the upper of the shoe; an attendant presenting, as may be required, the lasted shoe to the nose-piece of the machine, and at the same time operating the pedal of the machine by his foot, so as' to put the machine in operation and cause it to drive a nail through such part of the sole or welt and into the last where it may be desir able to have Vone inserted. My present iinprovements may be said to consist as follows, viz.: In certain mechanism, as hereinafter described, for regulating the feeding forward of the wire; also mechanism for actuating the main shaft of. the machine and holding it at rest under circumstances as hereinafter explained.

A denotes the stock, head, or frame for sup porting the operative parts, it terminating in or being provided with the guide-nose B, which Y each downward movement of the pedal.

has a vertical passage, a, leading down through it. Through this passage the nail, after being severed from the wire, is driven or forced by the nail-driver, shown at c. The said naildriver is fixed in the lower part of a carrier or vertical slide-rod, C, arranged in the frame or stock A, and provided with a spring, D; the purpose of which is to depress the carrier after each elevation of it, such depression being with power sufficient to cause the nail-driver to force the nail into the article into which it may be required to be driven. Within the frame or stock A, and disposed therein, `as represented, is the main shaft E, carrying a pinion, F. This pinion Vengages with a gear, d, arranged on a stationary arbor, e. fixed to the gear d, on one side'oi it, a ratchetwheel, f, (see Fig. 4, which is a side view of the ratchet and geen) with which a draw-pawl, g, applied to one side of a wheel, It, and provided with an actuatingspring, s, operates. The

wheel It turns freely on the said arbor, and

while in operation is to have a reciprocating rotary motion, such being to be effected by a pedal connected with the wheel by a rod, fi, pivoted to the two, a spring being used to elevate the pedal and rod. An entire revolution is to be imparted to the shaft E during A cam-wheel, lc, shown in side view in Fig. 5, receives in its cam-groove l a friction-rollerprojectin g from one side of an arm, m, such arm being extended upward from a shaft, n, to whose front end the transferrer'L is iixed, the latter deriving' its motions from the said shaft,

arms, and cam. Furthermore, there is iixed on the shaft E, at its front end, a cani or wiper, 0, whose purpose is to effect the elevation of the nail-driver carrier C at the proper times and to allow it to be driven downward by the spring D. The wire from which the nails are to be successively cnt is to be led through a passage, w, of a guide, I, and thence against the milled or toothed periphery of a feedfwheel, Kg-thence through a conduit, o, to and past the cutting-edge ofthe stationary cutter m, arranged as shown. From thence the wire passes into the passage z of the transferrer L. The

said transferrer carries a cutter, y, which, op` eratin g in conjunction with the stationary cutter w, serves, at the proper. period, to sever a There is nail from the wire. By the movements of the transferrer L the wire will be cnt or the nail will be severed from it by the cutters, and subsequentlywill be moved directly over the guidenose passage a, ready for being driven by the nail driver. There is applied to the periphery of the cam-wheel 7c a friction-brake or presser, a2, which, arranged in the frame, as shown, has a spring, b2, for forcing it downward, the elastic force or pressure of the spring being increased or diminished by a screw, c2,l screwed into the frame or head A and against the up# per end of the spring. Thisfrictiorrbrake is to prevent the cam-wheel from being revolved by its momentum beyond what may be necessaryV for its successful' action. The brake a2 is also to hold the shaft E from revolving while the pawl-carryingwheel his being moved backward so as to slip thepawl g over the ratchetwheel'j'. The feed-wheel K revolves on an arbor, 7d, projecting from the head A. A ratchet or pawl, l', carried by an arm, m', and arranged with the toothed periphery of the feed-wheel, in manner as shown, operates such wheel. The arm m projects from a shaft, n', which extends through the arbor k. From the rear end of such shaft n an arm, of, is` extended, and carries a friction-wheel, p', to act against the periphery of a cam, q', fixed on the outer side of the cam-wheel 7c, the shape of the cam q being shown in Fig. 6. There is connected to the arm o a spring, 1", which is fastened to a projection, s1, from the frame or head A, all being arranged as' shown. This spring draws the friction-roller closely upto the cam. Fig. 7 is a horizontal section taken through the axis of the shaft n and the parts adjacent and in the vicinity of such sha-f t. There projects back from the frame A, and concentric with the shaft n4, a tubular arbor, tf, which constitutes the fnlcrnm of a stop-lever, It, a top view of such lever being given in Fig. 8 and a side view of vit in Fig. 9. From the shorter arm u of such lever a stud, c', is extended against the inner edge of the arm o. The arm w of the stop-lever R is hollow or chambered to receive a spring, m', which is held in place inthe arm by a screw, y', screwed therein and against the outer end of the spring. the spring bears against the arbor t. From thesaid lever an arm, z', extends, in manner as shown, between the inner ends of two screws or adjustable stops, a3 b3, arranged in the frame A, in manner as represented. The purpose o'f the stop-lever R and its adjustable stops c3 b3 is to regulate the extent of movement of the arm o toward'the cam q', and, as a consequence, the feeding of the `wire in order to cause the nail cut off and driven to have any desirable length.

By taking hold of the arm fw ofthe lever R an attendant will be`able to move the stop-lever between its stopsA more or less, as may be Y lrequisite, to vary the feed of the wire, the

spring of the lever-sufficing to hold, by friction, the lever in the position in which it may be so placed.

In the above-described machine, whatIclaiin as my invention may be stated as followsthat is to say:

I claim the combination and arrangement of the stop-lever It, the adjustable stops a3 b3, the feed-wheel K, the pawl l1, the arm m', the shaft nf, the arm o", the spring r', the roller p,and the camfq, all being constructed and applied together, substantially in manner and to operate as described. j

Also, the combination therewith of the spring x', or such, and the adj Listing-screw y', arranged in the stop-lever, as set forth.

Also, the friction-brake c2 and its spring b2 and screws c2, in combination with the gea-rs F d, ratchet-wheel j', and reciprocating pawl g and its carrier It applied to the shaft E, and with the cam-wheel k of the mechanisms, as described, for operating the transferrer and feed-wheel. Y
