MATTHIAS BROCK, OF BOSTON, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO UNITED SHOE MACHINERY CORPORATION, 0F PATERSON, NEW JERSEY, A COR- PORATION OF NEW JERSEY.

END-LASTING MECHANISM.

To all whom t may concern:

Be it known that I, MATTHIAS BROCK, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in End-Lasting Mechanism, of which the following description, in connection with the accompanying drawings, is `a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and particularly to end lasting mechanism, being herein shown for illustrative purposes as embodied in mechanism for lasting the heel seats of turn shoes after the shoes have been sewed. i

Under some conditions in shoe manufacturing it is desirable to have end lasting wipers extend longitudinally of the shoe Vfor distances which vary in different shoes,

and in a co-pending application Ser. No. 36,736, filed June 28, 1915, is shown a wiper mechanism in which wiper members are adjustable lengthwise. In the mechanism illustrated in that application means is provided for effecting an adjustment of the side members of a two-part wiper and for retaining the adjustment. A feature of this invention consists in Wipers which are automatically adjustable lengthwise. This feature of thefpresentinvention is shown as embodied in mechanism which comprises means by which the wipers are automatically adjusted for each shoe and are returned automatically to a fulllength position after each shoe has been withdrawn from the machine. The illustrated embodiment of the invention is shown in the drawings asused in lasting theheel seats of turn shoes. When so used the adjustment of the wipers length wise to Vmeet the requirements of the work is effected automatically during the presentation of the work. Thewipers shown com.- prise endwise movable side members, as in said application, andthese side members have lconnections with parts which extend into .positionjtobe engaged by theupwardly and forwardlyV turned heel seat portion of the turnY shoe solev as the shoe-is jacked back, wardly into. the heel lasting, mechanism. The? solei thusv forces the wipers backwardly tothe length'requiredforrthe particular shoewhich is presented'to the machine, and

Specification of Letters Patent.

Application led July 7, 1915. Serial No. 38,552.

when the wipers are thereafter operated they last the full length of heel seat exposed for lasting in that shoe. VAs shown the wipers at the two sides of the shoe are independently movable so that each wiper is adjusted automatically to the length of the heel seat on the side of the shoe upon which that wiper is to operate.

This and other features of the invention will be made clear from the following description of the illustrative embodiment of the invention, considered in connection with the accompanying drawings, and the invention will then be particularly pointed out in the claims.

Figure 1 of the drawings is a plan view of a heel seat lasting mechanism embodying this invention and shows a turn shoe applied to the heel pin of the machine.

Fig. 2 is a similar View showing the wipers partially closed to present the wiper feelers in position for adjustment of the wipers to be efiiected when the shoe is moved backwardly into position to be operated upon.

F ig. 3 shows the shoe jacked back into the machine and the wipers adjusted for the length of the heel seat.

The opposed heel seat wipers each comprise a rear end member 2 and a side member 4. Members 2 are shown as pivotally connected together and as each connected near its outer edge to a link 6 which eX- tends lfrom a cross-head 8 on a plunger 9 operated by a hand lever 10. The wiper members 2 have cam slots 12 which coperate with relatively fixed studs 14 and they also have their outer edges in engagement with the sidewalls of the wiper recess in the wiper carrier 13. By these guiding devices the wiper members 2 are caused to advance and close inwardly over the rear end of the heel seat when the hand lever 10 is moved toward the left in the drawings. Each side member 4 is mounted in its cooperating end member to partake ofthe inward closing movement of member 2 but is restrained by a stud 15 from partaking of the advancing movement of the member 2. The stud 15 extends upwardly into a transverse slot in a slide bar 16 which is guided for movement longitudinally of the machine in the wiper carrier 13. 4 The slide bar 16 has a stud whichfstands in a slotin thewiper carrier and is pressed forwardly by a spring plunger 18. The side members 4 each sup ports at its 'free end a iceeler 20 which eX- tends inwardly therefrom toward the shoe and is shown as adjustably positioned transversely of the shoe by a screw 21. A spring 22 encircles the wiper operating plungerl 9 and holds the wipers normally in the posi tion shown in F ig. 2. The heel pin 24k upon which the last is supported has a rack and pinion connection, not shown, with a hand wheel 25 by which the shoe is drawn backwardly into the machine.

In the use of the machine the wipers are spread by moving the hand lever 10 in the direction of the arrow, Fig. 1, and the slice is applied to the heel pin 24, after which the spring 22 restores the wipers to the position shown in Fig. 2 in which the eelers 20 are in the path which the shoe will follow in being presented in position to be lasted. The hand wheel is then operated to draw the slioe bachwardly intoy the machine and through the contact oitl the upturned heel seat portion of the sole of a turn shoe, as seen in Fig. 3, with the feelers 2O serves to adjust the wipers for the length of the heel seat of the shoe which is to be lasted, this being effected by the pressure of the `turned back end of the sole sliding wiper members e backwardly against the pressure of the spring plungers 18 as shown in F ig. 3. rIhe shoe is then lasted by usual operation of the wipers over its heel seat and after the upper'has been tacked in lasted position the wipers are retracted and the shoe unjackedV and removed from the heel pin. j
