| To all whom it may concern: I

Be it known that l, WrLLnm B. Keros- LEY, a citizen of the United States, and residing in Vineland, New Jersey, have invented certain improvements in lVelt-Beating Machines, of which the following is a speciilcation.

My invention belongs to the general class of shoe making machinery and has to do more particularly with a novel device for operating on wclts.

hie obj! oi the invention is to provide means whereby it shall be possible to submit a welt to pressure or beating while it is being stretched or is under tension ;thatis, to provide means for simultaneously stretching and pounding or beating a welting with the idea of causing such spreading of said material that shall be capable of covering a larger surface than would otherwise bepossible.

Another object of the invention is to provide a relatively simple and compact mechanical device capable of being combined with any suitable form of mechanism. for beating a welt, by which it shall be possible to simultanmiusly beat and stretch the welt of a shoe.

These objects and other advantageous ends I attain as hereinafter set forth, refer? ence being had to the accompanying-drawings, in which,

Figure l, is an elevation of one side of a machine made in accordance with my invention; Fig. .2, is an elevation ofthe' opposite side of the machine shown. in Fig. 1; Fig. 3, is a plan of a portion of my device Fig. 4, is a side elevation of a modified form of my machine; Fig. 5, is an inverted plan of a form of clapper which may be used in my machine; and Fig. 6 is a side elevation of a modified form of 'my'invcntio'n.

In the above drawings A represents the supporting frame of a machine which is pro vided with any form of mechanism whereby a hammer ii is rapidly reciprocated in the well known manner, this hammer being carried upon one end of a rocker arm 6 driven from suitable mechanism such as an eccentric or crank actuated from a pulley b, and which, as its particular construction forms no part of the present invention, has not been illustrated in detail. in addition, there is also a worm fixed tothe belt wheel or driving shaft h and a worm wheel inclosed in a casing illustrated in dotted lines in llig. 1.

the end of a horizontal bar E which is free to slide in a guide box 6 suitably supported from the frame. The forward end of the slide bar E is turned downwardly and inwardly, as indicated in Figs. 1 and 3, so that it terminates preferably directly in the rear of the hammer B, and above and to the rear of an anvil F which is rigidly fastened to the projecting portion a of the frame so as to be immediately under the lower face of said. hammer B. Theanvil is held in position b a bolt (1, which passes through a slot in t e frame as indicated in dotted lines, so as to permit of said anvil being adjusted in or out as desired. Theslide bar E has extending through its forward. end a rod G which is provided wit a thin metallic tongue so placed as to rest upon the forward edge of the anvil F. Said rod G may be adjusted as to its osition in the enlarged end of the slide bar 4 and is held in any given position. by a suitable screw 6'; Also mounted upon the bar G and to the rear of the end of the slide bar E, is a block if held in any adj usted position on said rod by means of a set screw it, shown in Fig. 1.. A pin or bolt 7t extends transversely through the said block H and serves as a sup orting spindle or pivot for a clapper K, whicl f in the present instance is U-shaped in form and has a substantially semicircular extension 70 designed to project over the anvil F and tongue 9 while under thehammer B. With this ar rangcment of parts, when the machineis'in operation, the rocker arm'b' is caused to rapidly oscillate under the action of the eccentnc or other device on the main shaft 1; and the hammer is tl1orcby cau'sed to make a succession of rapid strokes toward and from the anvil B. At the same time the revolution of the cam 0 causes the lever D to be oscillated on its fulcrum, thereby reciprocating the slide bar E and moving the tongue g and the clapper K alternately forwardly and to the rear under the hammer B. The various parts of the machine are so proportioned and timed that the hammer Will usually make a number of strokes while the slide bar E and its attached parts are making one complete cycle of movements to the rear and toward the front, the hammer being 21d" justed so that it strikes the part oi the clapper K each time it descends.

. or stretched during the rearward movement of the sliding bar E.

Movement of the shoe is prevented because it rests against the abutment formed by the frontedge of the anvil, as shown in Fig. i, so that during the entire movement oi the slide bar E the welt strip may be lipped and released several times between the tongue and the clapper, beingthus not only beaten or pounded but simultaneously stretched.

'Upon the forward movement of the sliding bar E, the welt strip is beaten without being stretched and isagain beaten while under tension. upon the next rearward movement of the tongue and clapper, and so on indcii nitcly. The rearward motion of the tongue and clapper while they are pressed upon by the hammer causes a stretching of the welt ing, and, as illustrated in Fig. 5, I may in some instances roughen the under side of the cla )per so that it will better grip the welt.

)Wing to the construction described and illustrated it is possible to vary not only the positions or the amount of projection of the tongue and clapper relatively to the anvil h, but also their position relatively to each other and to the hammer B, thus making it pos sible for the device to be used to o 'ierate upon different sizes and grades of WO'EliZ.

It is to be noted that the anvil serves as the means for holding the body of the shoe so that tension may be applied to the welt thereof when this latter is gripped by the tongue and clapperand moved to the rear thereby. I 1

It is obvious thatif desired, the hammer may be reciprocated in a substantially horizontal line withthe tongue and clap er while the anvil remains stationary, inw1ich case the various parts may be arranged as shown in Fig. 6. V Vith such a construction the sliding bar E has a vertically slotted-projection e into Whose slot or slots extends a suit able pin or pins projecting from the vertical guide I) for the han'imer B. This guide is loosely connected with the end of the rocker arm I) and as a consequence, said hammer,

under operating conditions, is given. a horisenses zontal as well as a vertical reciprocating movement.

.l ii any of the above noted cases, elther the tongue or the clapper maybe omitted, though with said roller so that as said clapper is moved rearwardly by the rearward movement of the slide bar E, said cam face will engage said cam roller it". As arcsult, its forward end is moved toward the tongue and cc acts with it to grip and stretch the welting before. With the forward movement of the slide E, the extension of the clapper moves oil oi the roller 7t and releases the welt.
