acters on the drawings indicating like parts in the several figures. E

This invention relates to pulling-over ma chines and, it may be, has forits object to provide an improved machine for pullingover a shoe and also lasting the toe portion of the shoe, said pulling-over and lasting means preferably operating while the shoe remains in a single working position. The pulling-over mechanism may be of a known type or of any construction suitable for the purpose, and this invention consists in novel combinations with pulling-over mechanism of improved lasting means and also in the lasting means and associated mechanisms per se.

The present application is a division of application Serial N 0. 567,529, filed June 17, 1910 for improvements in machines for use in the manufacture of boots and shoes.

In the operation of pulling-over a shoe the upper is gripped and pulled at the opposite sides of the ball and at the tip of the toe and is drawn over the last and tacked at each of these places. At either side of the toe tack, that is, at the corners of the toe, the upper stands out in a projecting pucker which is called a dog-ear in the shoe shop.

An important feature of the present invention is embodied in novel means for turning inwardly'the fullness at the corners of the toe instead of allowing it to stand out and form these dog-ears. By forcing the upper inwardly at the corners of the toe at this stage of the manufacture of the-shoe, this fullness is distributed and prevented from localizing so that later operations are made easier. The devices which turn in the upper at the corners of the shoe are formed as lasting plates or corner wipers. These end lasting plates for wiping over the two corners of the toe are separate from one another as distinguished from the connected wiper plates of the bed lasting machines in common use. In one embodiment of this invention each lasting plate or corner bender is arranged to extend from the side of the shoe around the corner toward the middle of the toe and is mounted for inward movement transversely over the shoe bottom and also rotatively, the latter movement being about a center located at the rear of the toe and preferably near the rear end of the plate. The lasting plates may be carried into working position by power operated means, shown in the present embodiment of the invention as the inwardly moving side clamp carrying arms of the pulling-over machine. The plates may be so connected to said arms that they may be manually manipulated, if necessary, for further pressing the upper into the position required for the particular Shoe being treated. It is a feature of the illustrated embodiment of the invention that the end lasting plates are arranged to approach their working position by movements transversely of the last from opposite directions; also that they can be turned, each about its own center located at the rear of the toe of the shoe, to sweep the upper inwardly and backwardly over the end and corners of the toe.

Another object of this invention is to pro-- vide improved means for actuating end last ing plates which may be in the form of the corner wipers or benders before mentioned or of any other form to which such operating means is applicable. An important feature of this phase of the invention is found in mechanisms for actuating a wiper in sub-- St-antially a right line over the shoe and for turning the wiper, which mechanisms permit of separate right line and turning movements being effected. Another feature is found in the provision of mechanisms by which either one of a pair of end wipers may be moved lengthwise of the last inclependently of the other one of the pair, and a still further new feature provides for turning either end wiper plate independently of the other plate. In a further embodiment matic adjustments about axes which are respectively perpendicular to the plane of the shoe bottom and parallel with said plane as. wellas to yieldlat'erally of the shoe in the carrying arms. This mounting for end lasting devices whether actuated automatically or otherwise is entirely new as I am advised and is of obvious advantage, particularly in a machine in which the lasting devices are automatically operated. The arms on which the corner wipers are mounted are pivoted to swing about separate centers which are so located at opposite sides of the shoe-at the rear of the toe that the wipers have a backwardas well as an inward sweep to draw the upper rearwardly from the toe end of the last.

These and other features of this invention including certain details of construction and more important combinations of parts will be explained in the'follovving description' of a preferred embodiment of the invention-and will then be pointed out in the claims.

Figure 1 is a side elevation of'a machine equipped with this invention; Fig. 2 is a perspective showing the new mechanism.

The invention is herein shown for the purpose of explanation, as applied to'a machine like the well-known commercial pulling-over machine shown and fully described in United States Letters Patent No.'1,029,387, granted June 11, 1912. It is not necessary herein to show,'or to describe, that machine and its operation except in those particulars in which it cooperates with the lasting devices of the present invention, which are arranged to operate after the shoe upper has been pulled and adjusted upon the last and while the shoe is held in the machine with the upper under tension over the last, the powerdriven mechanism of the machine being temporarily at rest. It is contemplated that the machine shall be organized to come to rest with the side clamps closed against the sides of the shoe and the automatically actuated inswinging tack carrying arms 8 at the sides of the machine in'their tack inserting positions over the shoe.

The corner wiper plates 16 are supported upon the'usual side clamp carrying arms 62 of the pulling-over machine shown in said patent above referred to. The arms 62 extended rearwardly and are pivotally supported to swing inwardly toward the shoe about axes that are substantially perpenment of the arms 62 about their respective centers carries the corner wiper 16 laterally toward the shoe from opposite directions and that these wipers which project inwardly toward each other from the front ends of the arms are moved in the arc of a circle which carries them loackwardly as well as inwardlyas they'approach'and move over the corners of the shoe. This mounting gives to the wipers an automatic movement having 'a component of backward movement. In'Fig. 2 each wiper plate is connected to its arm 62 by a slide or wiper plate support 80 whichis movable endwise through 'a-rectangular guide 82 whichis attached to the side clampSet of the pullingover machine. This side clamp is mounted to have angular and sliding movements for adapting itself to the last .and therefore the wiper in Fig. 2 receives from the side clamp its movement to adapt its position tothe inclination, contour and size of the last. The slide 80 is connected by-a link 83, having ball heads, with a lever 85 which is fulcrumed on thearm 62 in a position'where it is within convenient reach of the operator whereby the lasting'plate may be given manually a. movement lengthwiseof the last to draw the upper rearwardly over the toe of the last. The wiper is also pivoted. to the'head of the slide 80 and has an outwardly projecting arm by which it is connected through-a link 86 with a lever '88 which is 'fulcrumed on the same pivot as lever 85 and is bent to cross lever 85 so that with the same hand an operator may press the two levers together and effect a backward and a turning movement of the wiper. The lovers are separated by a spring 90 and the operator can tell by the sense of feeling when the wiper has been pressed backwardly or turned inwardly or moved in both directions as far as is required-to wipe the upper against the lip or shoulder of the soleor inner-sole. A friction screw92 causes thewiper slide or support SOto maintain the position to which it is moved so as to hold the upper until it is fastenedor bound in by the wiring device of Fig. 1.

It will be noted that the wipers are pivoted in the rear ofthe toe for their inward turning movement and that as they also ap proach working position they have their initial working movement transversely of the shoe. It should'also-be appreciated that while the devices. 16 are herein termed wipers andare shown as having a construction and arrangement which enables them to have the well recognized functions of lasting machine end wipers in the production of a pulled over shoe having its toe fully lasted, it is within the broad scope of this invention to equip a pulling-over machine with devices which merely gather in or turn inwardly the upper material at the corners of the toe. The purpose of such devices would be to facilitate the subsequent lasting which may constitute an entirely independent operation. It will of course also be understood that wipers having the novel characteristics herein described may be employed in lasting apparatus which does not also include any pullingover mechanism.

In the use of the machine a shoe will be presented thereto and the upper pulled and adjusted as described and shownin said prior patent. The machine will then be restarted and caused to come to rest with the side clamps holding the shoe and side tack carrying arms closed over the shoe bottom. In this movement the corner benders or wipers 16 will have turned in the upper at the corners of the last between the side grippers and the toe gripper to prevent the formation of the out turned dog-ears. These devices may then be further manipulated, if the constructions shown in Figs. 1 and 2 is used, to wipe and press the upper into lasted position about the end ot' the last; then a strand of binding wire may be anchored and the binding device shown in Fig. 1 and described in divisional application Serial No. 657,538, filed Oct. 30, 1911, will then be manipulated to draw the wire tightly around the toe portion of the shoe to bind the upper against the lip or shoulder of the innersole. The toe gripper preferably retains its grip and assists the wipers and benders in holding the upper in position for the action of the binder thereon. Vhen the binder has been tightened and the supplemental tack driven at the other side of the shoe the machine is again treadled and caused to release the shoe. The operator receives the shoe in one hand while holding and manipulating the binding device with the other to twist and anchor the wire around its tack for securing it in holding position. 7
