Applicant inea october s, 189e.

To a/ZZ whom; jtm/ay concernf Be it known that I, CHRISTIAN EISENBERG, a subject of the :Emperor of Germany, residing in Berlin, Kingdom of Prussia, Empire of Germany, have invented 'certain "new and useful Improvements in 'Pulling- Over and Fastening Machines for Shoes, of which the following is a specification. K- v This invention consistsin a machine which takes the place of the pegging-machine used in shoemaking;H and its object is to unite the inner sole provisionally with' the upper, which for this purpose 'is providedI with an outwardlyextending rim.` The inner sole is united with this uppery by drawing pins or pegs, which after the sewing of the-sole is completed'ca'nfbe withdrawn.

In the accompanying drawings, illustrating the machine whichifornls the subject of my invention, Figure 1 is a topviewof the machine, someof ythe parts being broken away to make the construction'clearer." Fig'.- 2 is a similar View to Fig. 1, the parts, however, being shown in the operating position, while inFig. 1 they are in a nonfoperating position. Fig. 3 is a front elevation of the machine. Fig. 4 is a vertical section through the machine. Fig. 5 shows in plan view the pedalwork of the machine, thetableabove' same being removed. Fig.` 6 shows a pressing device used in the machine." Figs. 7 and 8 show the fastening devices for y the vlast holder. Figs. 9 and lOyshow the last-holder in top'and side views. "Fig 9a shows alsection of a part of the last-holder. Figs.' lland 12 show further details of thel pressing device. Figs. 13 and 14 show the pressing and driving device for the toe of theshoe. Figs. 15 land 16 show the fastening nails or pins. Figs. l17 and 18 show a stretching-clamp in top and side views. Figs. 19fand' 20""show details of a modified form ofpressinggdevice. Figs. 21 and' 22 serial No. 607,771. (No mtas.)

block b, which carriesclips or catches c. Into these catches are pushed the fastenings or hooks d with which the metal sole-plate or last-holder e is provided. a

, In the block is a draw bar or bolt f, provided at its` forward endwith a folding handle and heldv by a spring in position to allow the hooks d to be pushed freely into the catches c. The metal sole-plate 'e having been placed in position on the block, the draw bar or bolt f is drawn forward and a'nose f' thereby brought behind the rear hook d, so that the metal solepljate eis thereby fastened rigidly to the block b. A set-screw]E2 insures this fastening. On the metal sole-plate e a last is now placed carrying the upper orv shoe-body g and the inner sole. The fastening, of same can v conveniently be eifecte'd bymeans of screws Vpassing through holes provided in the inner'sole, the said holes being afterward closed up.

At the lower part of the machine are the pedals h h h2, which are connected with the three bars Il 'i' i2. There are also (see Fig. 5) four other bars lo 7.o k2 k3 in the Inachine,which can be connected with the pedals h h2 by the following devices: Around the bars t" and t2,

belonging to 'pedals hand 71.2, swing an gie-,arms v Z and Z,which by means of appifopriate` notches can be `connected one with either bar 7e or bar k3, the other with either bar 7c or bar 7a2. If,

as shown in Fig. 5, by throwing the angle-arm Y metal sole-plate e the stretching-clampsv (shown inwFig's. 17 and 1S) are placed onpappropriate parts of the upperg. ,Theshe'arnlike lconstruction of these clamps is such that wh'euwtheya're pulled the leather is tightly gripped, but isv readily released on withdrawing the tension. These stretching-clamps,

which are connected with bars i and la in any suitable manner,enable the upper to be drawn tight 'over' the last by the operation of the Ioo pedals 71 7L h2. Binding or clamping frames O O, corresponding in shape to the two sides ot the sole, are supported so as to slide crosswise of the table u and are moved by screwspindlcs operated by hand-wheels n. The upper having been pulled tight over the last, as above described, the frames O O are operated in opposite directions by hand-wheels n, so as to be brought up tight against the upper, impartingto it the shape shown in Figs. 21 and 22.

On each fra-me O stands a row of driving devices or jacks p, (shown in detail in Figs. 1l and 12,) each having a pin-holder or nailholderp. ln these pin-holders the U -shaped or staple-shaped pins or nails shown in Figs. 15 and 16 are pressed downward by springs. These springs are carried by caps held in place by catches. Each driving device p has at one end a bent lever q, engaging with a slide or bolt workin g beneath the pin-holder, so that when the upper arm of said lever is depressed its lower arm engages with the bolt yr, which takes a pin or nail from the pinholder and drives it out horizontally. rlhis causes the pin to penetrate the sole and upper in about a horizontal direction (or substantially parallel to the bottom of the shoe) and forces it iinally against the metal soleplate c. By means of round. depressions s in the metal sole-plate the inner ends of the U- shaped pins are bent inwardly or toward one another, thus for the time being uniting or binding together the inner sole and upper at those points. lVhen the upper arm of lever q is released, a spring throws back the bolt/'1l and allows another pin to fall into position to be driven out.

In Fig. C is shown a device which enables all et the levers q on one side to be operated by a single movement, and thus by means of the two hands to complete the binding together of the shoe by one movement. For this purpose a frame t is placed over all of the levers q, the same being pressed down by the hand-lever f, acting through the cam 2. rlhe cam t2 is pivoted in the trame of the machine and engages with a cross-bar connected to the frame t, as shown in Fig. (i. rlhe operation is such that as both the frames t move downward the angle-levers q turn on their pivots, the bolts rare all shot out, and a complete set of pins or nails is placed in the shoe except atthe toe, where this driving device is not present; but a special arrangement (shown in Figs. 113 and 1l) is provided. In this a small pin (shown in Fig. 1G) is lixed in a pineers u, carried by a holder sliding in a support on the frame. Then the latter, by means o hand -crank u', acting on a screw on the holder carrying the pincers, is brought against the shoe, and then through a blow on the press-button u? the clip is driven through the shoe-toe and there fastened. rlhe frames O are then withdrawn from the pinned shoe by turning baci; the hand-wheels u, the last is released by loosening the setscrewf?, the boltfilying back, and the nesef' being removed from the hookd. rlhe last is then removed from the metal sole-plate c, which is then ready to receive a new last. The shoe pinned together in this manner is then sewed in any desired way,.vhereupon the fasteningpins having become superfluous are withdrawn. The partly-iinished product thus obtained is then operated upon in any suitable manner, so as to fasten the under sole and heel to it and p ut it in merchantable condition.

To enable proper operation of the machine, it must of course be provided that the working surface of the frame O, surrounding the upper, is in strict correspondence to the form of the sole, as the pin-holders p must stand in such positions that they are always opposite the line of Linien of inner sole and upper. It is clear from this that in case ot any change in the form of the sole the trames O, and as a consequence the frames t, must be changed 0r else made to frt by the insertion of substitute parts. In Figs. 19 and 2O is shown a device by which this changing over or insertion of iitting pieces is rendered unnecessary. rlhe frame O is here so far changed that each pin-holder, together with the portion of the frame belonging to it, is separately mounted from the others. All these pin-holders here rest directly on the support e, which is opel.'- atcd by hand-wheel n. rl`he pin-holders y, which in this case correspond to workin g sections ot the frame O, each carry a little nose r', that is intended to bend the upper, as shown in Figs. 21 and rlhese pin-holders are supported from supports t' by means of adj usting-screws w, to which they are joined by a universal joint, thus enabling their distance from the sole-plate to be changed. A frame as is arranged on the side of support e and carries adjusting-screws 7], by which the height of the pin-holders relative to the soleplate is adjusted. lf now a sole of a difterent form is introduced, the pin-holders p arc iirst brought up to the sole by means of handwheels yn and then adjusted by operation ot the three adjusting-screws w 1/ exactly to the curves of the sole. It then the two supports yr are drawn back, a last with upper and inner sole placed on the sole-plate and the handcranlis u. again operated, each pin-holder will strike exactly on the proper spot and will,by means of the nose fr', bend the upper as desired, the driving of the pins being effected, as before, by a iframe and hand-lever.

llaving thus described my invention, the following is what l claim as new therein and desire to secure by Letters Patent:

1. A machine for manufacturing shoes, comprising a last-holder, stretchirig-clamps, devices for drawing down said clamps, trames corresponding in shape to the sides of the sole, and devices for bringing said frames up to said sole, and pin-driving devices mounted in said frames and adapted to d rive pins through the inner sole and upper in directions substantially parallel to the bottom. of; the shoe.
