The said driver is fixed in the lowerpart'ofa carrier .or -vertical sliderod, .0, arranged in guides in the-frameor stock A,:-and' provided withaspring, D,=Uil8 -.purpose of which is to depress the carrier-rod atter eachelevation .of ;it, such depression :hei'ng -with powerisnfficient tocause the driver to force the nail or tack 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 horizontal shaft E, carrying a pinion, F, on its rear-end.

This pinion engages with a gear, d, arranged on a stationary arbor, c.

There is fixed to the gear 01, on one side of it, a ratchet-wheel, f, (see 'Fig. 4, which is a side view ofthe ratchet wheel and gear,) with which a draw-pawl, g, Fig. 2, applied to one side of a wheel, h, and provided with an actu- Ming-springs, operates. The wheel It turns 'freely on a, sleeve of said ratchet-gear, and,

while in'operation, has a reciprocating rotary motion, efl'ected by a pedal connected with the wheel by a rod, '03, Figs. 3 and 3 A, pivoted to the two, a spring being used to elevate the pedal and rod," as shown in Fig.3 A. An entire revolution is imparted to the shaft E during each downward movement of vthe pedal. A cam'brake-wheel, k, (shown in side view in Fig. 5,) fixed upon the shaft E, receives in its cam-grom e l a friction-roll projecting from one side of an arm, m, such arm beingmounted upon and extending upwardfrom the rear end of a horizontal shaft, n, fitted in bearings in the lower part of the head, and to whose front end the transferrer L is fixed, the latter de- :riving its intermittent oscillating movements from the said sh aft, arm, and cam. This transferrer is secured to the lower end of a plate, L Figs. 11 and 12, which depends fromsaid shat't n, and has its movement close to the face of the head. The transferrer pro-per has the passage 2, into which the wire is fed and supported while the nail or tack is being cut off, and which passage is brought, by the action of the cam l, coincident with the nose-guide a and the driver when the nail or tack is to be driven. The transferrer, therefore, is arranged to operate between the nose-guide and the driver, in order that the nose may project free of any hinderance for the presentation and pressure of the sole thereagaiiist.

There is fixed on the shaft E, at its front end, a cam or lifter, O, to act against a nut, 0 to eflect the elevation of the driver-carrier O at the proper times, and to allow it to be driven down by the spring D, arranged in the turret. g

This nut O is screwed upon a thread on the driver-bar to allow said nut to be adjusted, and it is clamped by a screw, so that neither the nut or bar can turn as the bar is operated by the lifter. A collar on the driver-bar, cushioned with leather washers, acts upon ashoul der in the head, and limits the descent of the driver, the washers preventing too severe blows upon the collar.- These washers are renewed as often as is necessary.

Thedriver'c is fitted into a hole drilled in the end of the. bar an inchor more in length, and a narrow slit'is cut across the end for about the same length, over which slitted end a collar is fitted and provided with a screw,

which presses the two endsformed by the slits together, and thus holds the driver at any point, and allows it tobe removed if broken and another put in. v a

[The wire from which the nails or tacks are tobe successively cut is led through a passage,

.w,in a fixed guide, I, and thence between the guide K and the milled or toothed periphery of afeed-wheel, K,,thence through a conduit.

11, to and past the cutters, one of which isfixed horizontally at-the side, forming the wire-conduit v, and. the other to the transferrer. From the-conduit o the 'wire passes into passage z of the transferrer The said transterrercarries the movable cutter you a line with the top of its passage z, which, operating in conjunction with the stationarycutter 4r, serves at the proper time to sever a tack from the-wire. By the oscillation of ,thetransferrer L toward .the fixed cutter w, the wire will-be cut, or the nail or tack will be severed from it, by the cntters, as shown in Fig. 12, which is an enlarged view of the transferrer, cutters, and nose; and subsequently-that is, by the oscillation of the transferrer away from the fixed cuttcr thenail-or tack will bevmoved'directly'over' and in linewith the guide-nose passage 00,

ready to be driven'by the driver, as in Fig. 11,

which is a similar view to Fig. 12. By this;

construction and operation the nail or task will be cut by a distinct movement of the transferrer in one direction, and, by'a reverse movement, bringthe tack over the nose-guide. These two movements are effected by the cam l, and they are, of course, timed with the action of the driver and the feed of the 'wire.

There is applied to the. periphery of the cam-wheel k a friction-brake or. presser, a, which, arranged in the frame, has a spring, b, for forcing it againstsaid wheel, the elastic force or pressure of the sprin g being increased or diminished by a screw, 0*, screwed into the frame or head A, and against the end of the spring. This friction-brake is to prevent the cam-wheel from being.revolved by its momentnm beyond what may be necessary for its successful action. The brake a? is also to holdthe shaft E from revolving while the pawl-carrying wheel 71. is being moved backward, so as to slip the pawl gpver the ratchet-wheel f. The feed-wheel'Krevolves loosely upon a short arbor, k, Fig. 7, projecting from the head, and through which the ratchet-armed shaft n extends.

A ratchet or pawl, I, carried by an arm, m, and arranged with the toothed periphery of the feed-wheel, operates such wheel. The arm m is fixed to and "projects radially from the outer end of the shaft n, which has on its rear end a radial arm, 0, carrying a frictionroll, p, to act against the periphery of a cam,

q, fixed on the outer side of the cam-wheelie, the shape of the cam q being shown in Figs. 6, 13, and 14,'and its action on the arm 0 oscillates the shaft n, and moves the feed-wheel by the ratchet-pawL These is connected to the arm 0 a spring, r, Fig. 1. Which is fastened to a projectioin-s, from the frame or head. This spring draws and keeps the friction-roll closely up to the cam. Fig.7 is a horizontal sectiontaken through the axis of the doublearmed shaft n and the contiguousparts, showing the sleeved lever, its friction-brake, and the double-armed shaft at. There projects backward from the frame A, and concentric with the shaft n, a tubular arbor, t, Figs. 7, 13, and 14, which constitutes the fulcrum and bearing of the sleeved lever B, top and side views of such lever being given in Figs. 8 and 9, and sections in Figs. 13 and 14. From the short arm a, at the inner end of the sleeve of such lever, a stud, v, is extended to bear against the inner side of the arm 0', and serves as a stop for the latter. The handle w or lever B is hollow or chambered toreceive a spring, at, which isheld in place in the arm by a screw, 3 screwed therein andagainst the outer end of the spring as. The inner end of the spring bears against the sleeve-arbor t .by an intervening friction-seat, w, Figs. 13 and 14, and its force is regulated bythescrew y, and it serves as a brake to hold the sleeve-lever in its adjustment upon the fixed arbor t, and which adjustment governs, by the short arm u, the extent of movement of the long arm 0',' and the feed of the pawl. From said stoplever an arm, z, extends between the ends of two screws or adjustable stops, at b arranged in the frame A in line with each other, so as to limit the movement of said arm. The purpose of the stop-lever and the adjustable stops a b is to regulate the extent of movement of the arm 0 toward the cam q, and as a consequence the feeding of the wire, in order to cause the nail or tack out off and driven to have any desirable length.

By taking hold of the arm to or lever B an I attendant moves the arm z between the stops more or less, as may be requisite, to vary the feed of the wire the spring of the lever sufiicing to hold, b'y-the friction of a, bearingpiece, 00 upon the sleeve-arbor t, the lever in the position in which it may be soplaced.

By turning the lever down, Figs. 13 and 14,

- the stud '0' acts upon the inner side of the arm 0', and keeps 'it farther away from the cam g, as in Fig 14, and thus lessens the movement of the feed-wheel and shortensthe length of the nail or tack; but by raising the lever the stud v is carried awayfrom the arm-y o, and the latter thereby allowed to come nearer to the lesser-acting part of the cam q, and thus increase the movement of the feedtvheel and the length of thenail or tack, and

this adjustment of the lever is governed within fixed limits by the adjustable stops.

Figs. 11 and 12 represent front views of the transfer-rel and cutter devices .in did'erent positlona, thecutter-securing plates being removed,

in which Fig. 11 shows the transferrer in its ontwardmovement to bring its passage]; in line with the driver a, and Fig. 12 shows the trunsferrer in its inward movement to receive flie wire, and also to bring the cutters together to sever the wire. The fixed guide I for the wire is arranged just outside and between the feed-wheel K and a guide-roll, K, to give a proper support to the wire in being drawn into the fixed guide '0, which terminates just on the under side of the feed-wheel.

Figs. 13 and 14 showsectional "views 'of the sleeved lever B and, its short stop-arm u o, and the relation .it occupies to the arm- 0 of the ratchet-shaft n, in order to adjust and hold said arm 0' away from the lesser-actin g part of the cam q, as in Fig. 14, to diminish the feedmovement received by the arm 0 from the feed-operating cam.

cam, except when prevented from so'doin g the arm 0, as in Fig. 14,.to limit the inward movement of the latter.

The gnide-nose B, as shown in Fig. 10, prointo a seat formed in theunder side of the top face a 'of the nose end being level, and the shoulders'a a keeping it firmly in place, while the nose-bar B inclines upward out of the head A, to' allow it to be removed for adjusting and renewing the leather washers of the driver-bar. I

It will be observed that the lever B and the adjustable stops a b afi'ord the means for determining the maximum and minimum length of the tack, so that a definite length of nail will not exceed or fall short of a fixed length; and this is effected by moving said lever as far up or down as possible between said stops, while at'the same time this adjustment may be varied by the stops to give different lengths of tacks within such limits, and during the against the upward'pressure of the operators hands against the nose, which presents the tack.
