248,071. British United Shoe Machinery Co., Ltd., Silvester, R. H., and Bates, A. Nov. 27, 1924. Pulling - over. - Relates to machines of the kind having a plurality of grippers spaced along a side of the last, and fastening mechanism for securing the upper on the shoe bottom so as to hold it in stretched condition along said side; and wherein the construction and arrangement of the parts is such that a bodily movement of one of the grippers can occur without involving proportionate parallel movement of another. According to the invention a bodily movement of one of the grippers can occur relatively to a second gripper in a direction other than parallel to the axis of the second gripper. Preferably the rear gripper on the outside of the shoe is given a rear-draw, while that on the inside of the shoe is given a foredraw; the fore grippers may be given up-draw only. Separate up-draw levers are provided for adjacent side grippers and the separate levers are provided with a common retarding device of the kind described in Specifications 1866/12 and 181,474 to eliminate snatching action. The fore grippers at the side of the last are operated as usual before the stoppage of the machine for tipstraightening, but the rear grippers are operated after this stoppage, preferably by unbroken connections. The invention is described applied to a machine of the general type described in Specifications 7005/00 and 12304/03, but provided with four separate up-draw levers 21, 23, 25, 27, Figs. 1 and 2,. each resiliently operated by a spring 41 the upper end of which is engaged by an adjustable plug 39 carried by a yoke 37 actuated by the usual cam-operated slide 31. Wedge members of usual form are interposed between the yoke and slide to vary the initial compression of the springs 41. To delay the action of the rear grippers, their up-draw levers aro each held depressed during the first stage of the machines cycle by a toggle link 46 actuated by a link 53 pivoted to a bell-crank lever 55 urged clockwise by a spring. After the stop for tip-straightening, actuation of the starting treadle breaks the toggle and allows the rear grippers to operate, a third depression of the treadle re-starting the machine. To this end the treadle is connected to a composite rod 63 which at the end of the first stage of the cycle is pressed to the right against the action of a spring 64 by a cam 29. In this positioin the rod, when it rises, engages a block 62 on a rocking lever having an arm 60 operating the bell-crank levers 55 and breaking the toggles. In this position the rise of the rod 63 is limited by a stop 75, so that the depression of the treadle is insufficient to start the machine. The horizontal arm of one of the levers 55 supports a cam surface 69 which is thus depressed below a cam surface 66 on the rod 63 allowing this rod to move to the left out of line with the block 62, so that on the next depression the treadle may move sufficiently to re-start the machine. Dashpot retarding mechanism is connected to the shaft 125 on which is mounted a sleeve 127 in which can rock and slide a shaft 129 connected by sets of ball-and-socket-ended equalizing-levers with the four up-draw levers. The forward gripper casing 173 on each side of the shoe is guided by a link 227, the forward end of which is adjustable along a slot in an arm 231 carried by parallel links 247, 249 and adjusted by a link 239 pivoted to a crank on a spindle having a handle 251. The cranks for the grippers on the two sides may be oppositely disposed, when the handle 251 serves for tip-straightening. Alternatively, the crank discs may be mounted on the spindle so that either or both may be connected with the handle 251, which then serves for initial positioning of the front side grippers. Adjustment of the forward end of the link 227 varies the amount of fore-draw given to the gripper during the up-draw. The rear gripper casings are allowed play fore and aft of the shoe and are initially positioned forward and back for alternate right and left shoes by a link 333 with a slotted end adjustably pivoted to a pin 331 adustable radially in a disc 329 turned half a revolution each cycle by a pawl 325 carried on a plate in one with a pinion gearing with a segment 315 oscillated by the usual heel rest slide 301. If two similar shoes are to be dealt with successively, the crank disc 329 is turned by a handpiece 339. The cranks 331 are oppositely disposed on the two sides of the shoe. The forward end of the link 333 is pivoted to a slide 337 formed with a head 343, Fig. 8, on which are guided the rear gripper casing and the wipers and tackers. The wipers and tackers slide on a T-shaped guide so that they can move to and from the shoe as usual, but the gripper guide is adustable to predetermine whether fore draw or rear draw is to be given. The gripper casing 183 is linked to a slide rod 365 in a guide way pivoted on a spindle 361 and adjusted angularly by teeth on a rock shaft 345 mounted in the head and provided with a crank ball-and socket jointed to a block 351 sliding in a guide block 353 adustably pivoted on a fixed pin 355. If the guide-block is canted, movement of the slide 337 produces rocking of the shaft 345 and consequent tip of the gripper guide, which results in fore-draw or reardraw when the machine is in operation. The tack driver bar carries near its lower end swing- ing links carrying driving blocks, the swinging links compensating for the variation in position of the drivers dependent on the final position of the respective fore and rear wiping and tacking mechanisms. Specification 178,919 also is referred to.
