1'0 all whom it may concern Be it known that I, LOUIS GODDU, formerly of the Dominion of Canada, but now a citizen of theUnited States, and residing in Boston, in. thecounty of Suii'olh and State of Massachusetts, have made a new and useful invention or Improvement in Machines for Tricking Shoe-Soles or various other articles with wire; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which-- Figure lie at front elevation, Fig. 2 a side view, and Fig. 3 a vertical longitudinal section, of the head of a tacking-machine with my improvements or invention; and F153 represents a view, in perspective, cfthe head as mounted upon its standard, end con nected with the operating-Wendie, and showing the'manner of presenting end supporting the shoe to the nose by hand.

Such other figures or drawings as may he necessary to a full or proper illustration oi my invention will he hereinafter referred to and described.

The machine exhibited by the said drew" ings is analogous to that patented to me November 23, 1869, No. 97,192, and reissued December 14, 1875, in the particulars of having a cutter carried by an interznittentlyosciilnt ing transferrer, into which the wire is fed, the nail severed and transferred in position to receive-the action of the driver, and in connection. with which feeding mechanism is employed to feed the wire to the cutters and transferrer. l

The sneeinl object for which the present machine is designed is the fixing of soles or Welts in piece by 3- l'ew nails or tacks prepare tory to their being regularly pegged, nnilcd, or sewed to, the upper of the shoe, nu attendant presenting, as may he required, the lasted shoe to the nose of the machine, and at the same time operating the giednl of the machine by his foot, so as to put the machine in opera tion, and cause it to drive it nail or tech through such part of the sole or stock where it may be desirable to have one inserted.

The invention claimed under this patent consists of a machine for tacking or laying the soles of boots and shoes to their uppers, constructed and organized with n fixed upright frame, tack feeding and driving mechanism under the control of the operator, and an unobstructed down wnrdly-proj out i ng guidenosc lILl UB, small enough to enter the SO,lB-0ll?fll-.

nel, and oriented to receive it hoot or shoe at the hands of the operator, and to allow of the free inanip g httion of the Work to present the sole at will in all directions and angles to receive the tech or tacks, the design being to adapt the machine for tacking with a workmen, who, while holding the work in his hands, supports it by his force, and gives it, by his will, every direction and guidance, beconiings substitute for the jscksnpport and feeding inechztnism, with the advantage of obtaining; a. celerit oi operation which it is impracticable to obtain with jecksupports.

In feet, n inch-support is e hindcrcnce and an obstruction as compared with my machine, as organized with the free end unobstructed space for occupancy by the workmen While at Work, with, his hands performing the func tions of the work-support, the feeding, and edgegnide devices,

The guide-nose tube is constructed with special fitness toenter the channel of the sole, and serve as a guide for the work While it is inoved'i'rom one point to another by hand to receive the techs, and in shifting the position of the Work the nose can he kept within the chnnnel, and so guide the work, while serving as at guide for the techs. No such operation is obtained with ejech. The machine is or.- gnnizcd to cut end drive at nail, and then stop, which is essential to s tucker Each tech hes power applied, and the may chine then stops, for only one tech is needed at on point, end when the shoe is properly placed the power is again applied by the treedlc, thus giving intermittent motion at the will of the operator,

in ell organized nailingor pegging machines heretofore used, eithere; teed 'inechsnism, jEWlK-SHPPOZZ, owl, or edge-guide, have been employed. Any one of these devices would he an injury, end,in fact, make my machine ened slightly by hand before the last was removed to sew on the sole, or before it was permanently fastened with pegs or screwwire.

If this were not done the sole would get out of place in sewing or nailing. From eight to ten nails or tacks, ormore, are required to secure a sole so as to hold it properly in place 'for nailing or sewing. By my machine a man can do from eight hundred to one thousand pairs daily.

The nose of the machine is made small, so as to enter the channel of the sole in sewed work, and being free from feed device, edgeguide, or support. The operator takes the lasted shoe in his hands, places the sole in the proper position thereon, presents it to the nose, and operates the treadle so as to set the machine in motion, and drives the tack, and so'continues the operation, using the upward pressure of his hands to keep the sole close to the nose until the sole is laid.

In this operation the 'sole' is fed by hand, first presenting the toe andthqn the heel, and wherever a nail or tack is needed.

A dcnotes'the stock, head, or frame for sup porting the operative parts, and it terminates in,or is provided with, the guide-nose B, which has a vertical passage, a, leading through it. The nose is small, and projects a suificient distance down from the head to enter the channel and allow the sole to be moved along freely over it, as shown in Figs. 34 and 10,

which latter is .a perspective view of the nose detached.

Through the passage a the nail or tack, after being severed from the wire, is driven or forced by. the driver. (Shown at 0.) The said.

driver is fixed in the lower part of the bar or vertical slide-rod O. This bar is arranged to move in hearings in the frame or stock A, and

is provided with a spring, D, the purpose of" which is to depress the driver-bar after each elevation of it, such depression being with power sufficient to cause the driver to force the nail or tackinto the article into which it may be driven. I

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, (1, arranged on a-stationary arbor, c. There is fixed to the gear d, on one side of it, a ratchet-wheehf,

(see Fig. 4, which is a side view of the ratchetwheel and gear,) with which'a draw-pawl, g, Fig. 2, applied to one side ofa wheel, h, and provided with an actuating-spring, s operates.

sage is brought-,by the action 0! than The wheel It turns freely on a sleeve of said ratchet-gear, and, while in operation, has a reciprocating rotary motion, .eflected by a pedal connected with the wheel byn rod,4', Figs. 3 and 3, pivoted to the two, a springbeing used to elevate he pedal and rod, as

shown in Fig. .3. ,An entire revolution is imparted to the shaft E during each downward movement of the pedal. A cam brakewheel, k, (shown in side view in ,Fig.5,) fixed upon the shaft E, receives in its cam-groove l a friction-roll projecting from one side of an arm, m, such .arm being mounted upon and extending upward from the rear end of a horizontal shaft, n, fitted in hearings in the lower. part of the head, and to whose front endthe transferrer L is fixed, the latter deriving its intermittent oscillating movements from the shaft-arm and cam.- vThis transferrer in secured to the lower end of a plate, I), Figs. It

and 12, which depends from said shalt m1 and has its movement close to the facepf the The transferreiproper has the passage mints which the wire is fed and snpportodwhilo'th nail or tack is being cut 03, and whi incident with the nose-girl I when the nail or tank isto be 'drivouk The transferrer, therefore, is amngedlto o between the nose-guide and'the driver,- a order that the nose may; project free of' ny' hinderance, for the presentation and p re of the sole thereagainst. 1

There is fixed on the shaft E, at its '1: end, a cam or lifter, 0, to efl'eot the elevation of the-driver-carrier U at proper times, and to allow it to bedriven'down by the spring D, arranged inthe turret.

The wire from-which the nails or tacks are to be successively out is fed through a pasing' the wire-conduit '0, and the other to the transferrer'. From the conduit o the wire passes into passage Z of the transfer-rev.

The said transferrer carries the movable cutter 3 on a line'with the top of its passage I Z, which, operating in conjunction with the stationary cutter'w, serves, .at the proper poriod, to sever a nail or tank from the viral 7 By the oscillation of the transihrrer Ltoward the fixed cutter as, the wire will ho cat,"-

or the tack will be severed from it, bytho cutters, as shown in Fig. t2,'and' subsequentlythat is, by the oscillation of the transforrcr away from the fixed cutter-thetackwill he moved directly over and in line with the guide-nose passage a, ready to be driven the driver, as in Fig. 11.

By this construction andoperation, the task will be cut by a distinct movement of the trans-- ferrer in one direction, and, by a reverse movement, bring the tack over the guide-nose.

These. two movements are efl'ected by at cam l, andthey 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 70 a friction-brake or presser-foot, a, which, arranged in the frame, has a spring,

,1), for forcing it against said wheel. the clastic force or pressure of the spring 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 momentum, beyond what may be necessary for its successful action. The brake a. is also to hold the shaft E from revolving while the pawlcarrying wheel h is being moved backward, so as to slip the pawl 9 over the ratch et-wh'eel f.

v f 'lh'e feed-wheel K revolves loosely upon a -'short arbor, k, Fig. 7, projecting from the head, and through which the ratchet-armed shaft 1: extends. A ratchet or pawl, l, carried by an arm, m, and arranged to act with thetoothed 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 friction roll, p, to act against the periphery of a cam, q, fixed on theouter side of the cam-wheel k, the shape 'of the cam q being shown' in Fig. 6, and its action on the arm 0 oscillates the shaft n, and moves the feed-wheel by the ratchet-pawl. There is connected to the arm 0 a spring, r, which is fastened to a projection, 8 from the frame or head. This spring draws and keeps the friction-roll closely up to the cam.

Fig. 7 is a horizontal section taken through the axis of the double-armed shaft 1:. and the contiguous parts, showing the sleeved lever, its friction-brake, and the double-armed shaft 10.. There projects backward from the frame A, and concentric with the shaft n, a tubular arbor, t, Fig. 7, 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. From the short arm u, 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 serve as a stop for the latter.

The handl e or lever B is hollow or chambered to receive a spring, :0, which is held in place in the arm by a screw, y, screwed th re-- in and against the outer end of the spring. The inner end of the spring bears against the sleeve-arbor t, and its force is regulated by the screw 3 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 n, the extent of movement of the long arm 0 and the feed of the pawl. From said sleevelever an arm, 2, extends between the ends of two screws or adjustable stops, 0. b arranged in the frame A, in line with each other, so as to limit the movement of said arm The purpose of the sleevelever and the adjustable stops a b is to regulate the extent of movement of the arm 0 toward of the wire. the spring of the lever sufiicing to hold, by the friction of a bearing-pieceupon the sleeve-arbor t, the lever in the position in which it may be so placed.

Byturning the lever down, Figs. 13 and 14, the stud 1) acts upon the inner side of the arm n, and keeps it farther away from the cam g, and thus lessens the movement of the feedwheel and shortens the length of the nail or tack; but, by raising the lever, the stud 'v is carried away from the arm 0, and the latter thereby allowed to come nearer to thelesser acting part of the cam q, and thus increase the movement of the feed-wheel and the length of the nail 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 transferrer and cutter devices in different positions, the cutter-securing plates being re moved, in which Fig. 11 shows the transferrer in its outward movement, to bring its passage a in line with the driver, and Fig. 12

shows the transferrer in its inward movement,

to receive the wire, and also to bring the cutrers 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 show sectional views of the sleeved lever B, and its short stop-arm u v,

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 acting part of the cam q, as in Fig.14, to diminish the feedmovement received by the arm 0 from the feed operating cam. The spring 1" holds the arm 0' up to the cam, except when prevented from so doing by the stop-stud u, adjusted to bear against the arm 0', as in Fig. 14, to limit the inward movement of the latter.

The guide-nose B, as shown in Fig. 10; projects from the end of a bar, B, which is bolted into a seat formed in the under side of the head in an upwardly-inclined position, the top face a of the nose end being level, and the shoulders a. a. keeping it firmly in place, while the driverrises out of the way of the nose, leaving the latter free for use, as before stated.

The free and unobstructed space referred to extends beneath and around the guide-nose tube in front of the standard, and furnishes the unobstructed working space for the person who supports and controls the work and governs the operation of the machine.

Besides obviating the disadvantages of the fixed jack-support, feed device, and edge-guide,
