chines and particularly to the upper pulling mechanism thereotand is shown as an 1mprovement upon the upper pulling mechanism disclosed in Letters atent of Great Britain No. 16337/1908.

In machine pulling-over, that i." initially pulling the upper at the critical points' at .the end and opposite sides of the orepart and adjusting it if: necessary into general conformity with the lines of the last preparatory (to lasting, the upper is usually seized at each side oli the shoehy two grip-v pers, one of which pulls the upperY at and adjacent to the toe tip line or seam and the other of Which -pullstheupper in the rear'- ot the seam. The belt ot upper engaged at 'opposite ends by the tvvo rear grippers also the tip seam.

stretches more than that engaged by the two 'front grippersy for severa-l ressens; lt is usually longer because of increased Width oi the last and it is usually more elas tic because the :front gripper seizes the inelastic tip stillening material and frequently' Also on 'seine styles et' last the top face is low over the ball-ot the last so that the rear belt ot upper requires to be pulled down into this 10W portion of the last. To meet these conditions, the two grippers operating on the sam'eside of the last have been connected to their operating mechanism by means which permits them to move relatively for pulling the two. hands of upper as required. ln said prior patent prov1s1on is madeA for imparting a l predeten.

mined greater extent or movement to the rear grippers. Inasmuch, however, 'as conf ditions vary in diiferent shoe uppers and in dierent styles voli'lasts, an operator sometimes linde need, for-the purpose of making the desired initial stretching and position-l ing of the upper preparatory to lasting, -to move the two side grippers relatively. This need is sometimes indicated by .the presence is herein shown as embodied and will then particularly point out the features of the in-j l vention in the annexedl claims.

" The drawings show a side elevation of one o'lL side gripper mechanisms of a commercial pulling-over machine of Well known construction, parts being'shovvn in section to disclose the operating devices. The gripper mechanism includes or is Suspended 'from lever 2 tulcrnm'ed at 3, and connected at its rear .end to `the machine cam not shown. The operating har 4; has a. halls-con!- neet-ion with the lever and e lifting conne/o tion, including the springs 5, with the pairs oi2 gripper jaws. This connection also, as herein shown, includes the lost motion van rangement at 6 which is described in said patent for giving to the-rear-pair of jaws or the gripper 8 a predetermined extent of uplifting movement greaterthan, and preferably prior to, thatimparted to the front gripper 9 which engages Ithe belt of upper which includes the tip seam 10. The'lever i2 is extended forwardly from the operating oar i to forni a hand piece i2 by which the operator cen further uplift'or can depress, thegrippers for adjusting or changing the tension on the pulled upper after theautomatic pulling operation of the machine.

in accordance with this invention'. one of the grippers, herein shown as the forward gripper 9, -is connected by a link 14 with an auxiliary lever yi5 pivoted upon the lever 2'- andhaving a hand piece 16 arranged adjacent lto `the/ hand piece l2. lnl this position the operator can seize either or both of the hand pieces l2 or 1G Witlionehand. l'By sion on the two belts of upper for better vfitting it upon the last.

combination, side grippers to engage two,

belts of upper extending transversely about the last, means for actuating thel grippers to put the upper under tension, and means for actuating the grippers for relatively adjusting the tension on the two belts while the grippers hold the upper.

2. A pulling-over machine, having, in combination, sidev grippers to engage two belts of upper extending transversely about the last, means for actuating the grippers to put the upper under tension, and means for manually moving one side gripper relatively to the other on the same side While they hold the upper.

3. A' pulling-over machine, having, in combination, side grippers to engage two belts of upper extending transversely about the last, means for actuating the grippers to put the upper under tension, and means for further uplifting the .front gripper alone at thewill of the operator.

4. A pullingsov'er machine, having, in combination, side grippers to engage two belts of upper extending transversely about the last, means for actuating the grippers to put the upper under tension, and additionall means for moving one of said side grippers independently.

5. A pulling-over machine, having, in combination, side grippers to engage two belts of upper extending transversely about the last, means for actuating the grippers to put the upper under tension, and crossed 40'hand pieces arranged to be seized by one haifdof the operator for actuation to move l 7 t e two grippers simultaneously in opposite directions.

6. pulling-over machine, having, in combination, two side grippers, means for automatically actuating said grippers constructed and arranged to move the rear gripper farther than the front one in pulling the upper, and means for manually moving the front gripper more while the upper is held under tension by the two grippers.

7. A pulling-over machine, having, in combination, two grippers located on the same lateral side of the last, automatically actuated means to uplift the grippers together, and manuallyactuated means to uplift them separately.

8. A pulling-over machine, having, in combination, two grippers'located on the same lateral side ofthe last, automatically actuated means to uplift the grippers together, and manually actuated means to lower one gripper and further uplift the y other.

second lever for uplifting one gripper to be transmitted also through the fulcrum connections to the other lever for lowering the other gripper.

10. A pulling-over machine, having in combination, a gripper mechanism comprising two pairs of jaws for engaging adjacent portions of the upper, means for actuating said mechanism to put the upper undertension, and a lever connected with one of said pairs of jaws for additionally tensioning the upper.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
