STUD OR HOOK SETTING MACHINE.

SPECIFICATION forming part. of Letters Patent No. 394,228, dated December 11, 1888. Application filed July 30, 1888. Serial No. 281,409. (No model.)

T0 all whom it may concern,.-

Be it known that l, SETH D. TRIPP, of Lynn, county of Essex, State of llilassaehusetts, have invented an Improvement in Stud or Hook Setting Machines, of which the following description,in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to machines for attachin g metallic studs or hooks to leather and other material, and is especially adapted to attach the studs or hooks employed in laced shoes, such as now commonly worn.

In accordance with my invention, the studs or hooks placed in a raceway are taken one by one by a feeder and carried forward over an anvil, the said stud or hook when in such position having its head seized by jaws, which hold it lirmly, so that the prongs or legs of the stud or hook are forced through the leather or other material, the said operations taking place at each movement of a treadle, and being properly timed with relation to each other, as will be described.

My invention therefore consists, essentially, in a stud or hook sett-ing machine, a sleeve, and driver-levers movable with said sleeve and provided with jaws, and a spindle, and a wedge movable with said spindle to operate said driver-levers, and a raceway, combined with a feeder and means to move said feeder in opposite directions, substantially as will be described.

Other features of my invention will be pointed out in the claims at thc end of this specification.

Figure l is a side elevation of a suicient portion of a stud or hook setting machine partially broken out to enable my invention to be understood; Fig. a longitudinal vertical section of the machine shown in Fig. l; Fig. 3, a detail to more clearly show the pivoted jaws and nose or plate; Fig. 4, a detail to more clearly show the stud or hook feeder; Fig. 5, a section of Fig. l on line af a, just above the feeder; Figs. t and T, details to be referred to,

and Fig. S a view of a stud or hook.

The hollow casting c, provided with the hollow post a', by screw a3, in staple or button setting machines.

in which the anvil a2 is secured may be such as commonly found The casting d is secured, as herein shown, by a screw, ai, to a hollow upright, a5, which in practice rests upon the floor, the said hollow upright. receiving within it a sleeve-like portion or flange, a, of the casting a.. t

The casting a has extended through it a hollow cylinder or sleeve, CLT, normally held stationary by a friction-pad, as, attached to a spring, a9, fastened to the casting u, the said friction-pad being extended through a hole in the said casting. The hollow sleeve ci has extended through it a spindle or rod, l), having at its upper end above the sleeve aT an arm, b', provided with a wedge, h2, herein shown as a conically-pointed screw, the said rod being provided below the said sleeve with a collar, b3, herein shown as resting on a spring, b", which, as shown in Fig. l, encircles the rod h, and rests upon a ledge or shoulder, h5, of the hollow upright, the said spring normally acting to raise the rod b and sleeve o7 into their elevated position, (shown in Figs. l and 2,) when pressure is removed from a treadle, (not shown,) but which is connected to the rod h6 by a link, 197, the rod h being pivoted, as at h5, (see Fig. 2,) to the rod h,

The casting a has secured to it an arm, c, provided, as shown, with a spring-extension, c', to support a stud or hook holding tube or guide, c?, which forms a continuation of a raceway, c3, firmly secured to said arm and extended through a slot in the sleeve and a slot, c4, in the rod h, the said raceway being provided, as shown, with a curved foot portion, c5. The sleeve al is provided 'ith arms c, having shoulders cT extended at right angles thereto, and between which is located a carriage, CS, provided with a slot, 0.9,which receives, as shown, a block, cl, mounted on a screw or rod, cl2, extended through the arms c6, the said rod or bar being provided with a nose or plate, c4, constitutin a gage by which the forward movement of the feeder is limited, the said carriage having secured toit one end of a spring, cl3, the outer end of the spring being fastened to one of the arms c, the said spring permitting the bar ce to move vertically a limited distance, for a purpose to be hereinafter described.

The shoulders c7 have pivoted to them, as at d, driver-levers d', bent at their lower ends to form jaws d2, by which a stud or hook de-A livered from the raceway is seized,'the said jaws being normally spread apart by springs d3, (see Fig. 3,) one end of the said springs being secured to the shoulders c7, the opposite ends of the said springs being made to engage studs (Z4 on the levers.

The studs or hooks are taken 011e by one from the nose of the raceway by the feeder, herein shown as a curved plate, e, slotted as at e, (see Fig. 5,) and provided with recesses e2, into which enter the legs or prongs of the stud or hook 7L when the feeder is moved forward to place the stud or hook over the anvil a? and in position to be seized by the jaws d', as will be described.

The feeder is secured to or forms part of a feeder-bar, e4, extended through slots in the spindle, sleeve, and also through a vertical slot in the casting a The feeder-bar e4, as shown in Figs. 5 and is cut away at one side to leave a cam-path, as f f2, about a projecting portion, e", with which co-operates a stud, e, hereinshown, forming part of a plate, e7, secured to the casting a, the said stud directing the path of movement of the said feeder-bar and its attached feeder.

In operation the parts normally occupy the elevated position shown in Figs. l and 2, the pressure at such time being removed from the treadle, the feeder-bar and its attached feeder at such t-ime being pressed forward by a spring, f, to place a stud or hook substantially over the anvil, the said spring having' one end attached to the casting and its other end resting against the feeder-bar,the lower edge or bottom of the projection e5 being at such time above the stud e, which is then in line with'the channel or passage f (see Fig'. 6) of the cam-path f f2. The forward movement of the feederis limited by the nose-plate c, against which strikes the stud or hook held by the feeder. XVith the stud or hook above the anvil the operator depresses the treadle, which iirst acts on the spindle or rod b through the hook bl and rod b, to move the wedge b2 down between the upper end of the driver-levers, and thus force the jaws toward each other, the said jaws passing under and engaging the head of the stud or hook. `While the spindle Z) is moving down, the sleeve a7 is held stationary by the friction-pad until, on the further depression of the treadle, the arm on the spindle strikes the upper end of the sleeve, so that on the continued depression of `:he treadle the sleeve and its attached parts Atre moved down. As the sleeve moves down lhe channeled part f in the descent of the feeder-bar descends below the stud e6, and is the jaws approach the anvil the stud clears lhe channel, and as the stud comes above the nclined side of the projection e5 the spring '3 is permitted to act and gradually withdraw he feeder from the legs of the stud or hook, he feeder-bar being moved backward. The eeder is now out of the path of movement of he driver-levers, and the nose c at such time 'rests on the stock supported bythe anvil. On the further depression of the treadle the legs of the stud or hook are driven through the stock by the jaws of the driver-levers. The said jaws rest on the shoulders of the stud or hook. The pressure is now removed from the treadle and the spring 1) acts to restore the machine to the normal position shown in the drawings, the spindle being first acted on to withdraw the wedge from between the jaws and permit the springs (Z3 to open the jaws and release them from the stud driven into the stock. On the further upward movement of the spindle the collar b3 acts on the lower end of the sleeve c7 and moves the feeder-bar upward until the said bar is above the stud e, when the spring f moves the said bar forward to engage the feeder with the legs of a stud or hook and place the stud or hook in position to be seized by the jaws, as above described. As the parts descend, as described, from the position Fig. l, the pin on the feederbar acts against the spring f3, and as soon as the inclined part of the projection e5 arrives opposite the stud e the said spring acts to move the feeder-bar, as described, away from the jaws, and at this time, as will be understood, the rear cam-shaped end of the feeder-bar has passed below the upper end of the spring f, leaving it resting against the set-screw 3l. As the parts rise from their lower position the beveled rear end of the feeder-bar meets the shouldered part 32 of the spring jiwhich latter, stronger than the spring 3, moves the feeder-bar to take a stud or hook and place it, as described, into the jaws.

I claim l. In a stud or hook setting machine of the class herein described, a sleeve, and driver- IOO levers movable with said sleeve and provided with jaws, and a spindle, and a wedge movable with said spindle to operate said driverlevers, and a raceway, combined with a feeder and means to move said feeder in opposite directions, substantially as described.

2. In a stud or hook setting machine of the class herein described, a casting, a sleeve vertically movable therein, arms attached to said sleeve, and driver-levers pivoted to said arms and provided with jaws, a spindle, and a wedge movable therewith to operate said driver-levers, and a raceway, combined with a feeder and means to move said feeder in opposite directions, substantially as described.

In a stud or hook setting machine of the class herein described, a sleeve, and driverlevers movable with said sleeve and provided with jaws, and a spindle, and a wedge movable with said spindle to operate said driverlevers, and a raceway, combined with a feeder and feeder-bar provided with a cam slot and projection, a stud, and means to move said feeder-bar in opposite directions, substantially as described.

4. In a stud or hook setting machine of the class herein described, a sleeve, and driverlevers movable with said sleeve and provided with jaws, and a spindle, anda wedge movable with said spindle to operate said driverlevers, a movable nose-plate or gage, and a raceway, combined with a feeder' and means to move said feeder in opposite directions, substantially as described.

In a stud or hook setting machine of the class herein described, the combination, with a raeeway to hold the studs or hooks, of a feeder to engage a stud or hook in said raceway and a movable nose-plate or gage to limit the forward movement of the said feeder to place the stud in correct operaiive position, sulistantially as described.

d. In a sind or hook setting` machine of the class herein described, a casting' and sleeve movable therein, and a raceway to hold the `studs or hooks, combined with a feeder, anda feeder-bar provided with a cam groove and projection, and a stud, e, to eo-operate with said cam, and means to move the said feederbar in opposite directions, substantially as. described.

7. In a stud orliook setting machine of the cla-ss herein described, a vertieally-movable spindle and attached wedge, combined with a feeder and with pivoted jaws actuated by the said wedge to grasp the stud or hook, and with means to move the said jaws to drive the legs of the stud orhook into the material, snbstanw tially as described.
