(39.) In a lasting-machine, a shoe-bottom rest comprising a shank and a contact-piece rotatably mounted thereon. (40.) In a machine of the class described, a shoe-rest provided with a rotatable contact-piece for engagement with the shoe to be lasted, a presser for forcing the upper material of the shoe into lasted position, and means for actuating said presser to force the upper material into position and feed the shoe with relation to the shoe-rest. (41.) A lasting-machine comprising grippers, mechanism for actuating the grippers to pull the upper, and yielding means for turning the grippers. (42.) In a lasting-machine, grippers and means for actuating them to stretch the upper, in combination with means for turning said grippers, said means comprising an actuator and mechanism connecting said actuator with said grippers, said mechanism comprising a yielding element through which the movements of the actuator are transmitted to the grippers, whereby the turning of the grippers is yieldingly effected. (43.) A lasting-machine comprising grippers, mechanism for actuating the grippers to pull the upper, and yielding means for turning the grippers in both directions. (44.) In a lasting-machine, grippers and means for actuating the same to stretch and plait the upper, in combination with yielding means for turning said grippers in either direction during the plaiting operation, said means comprising a lever having a chamber therein, a plunger movable in bearings in said chamber, said plunger having enlarged portions near its ends, collars loose on said plunger between said enlarged portions and adapted to be stopped thereby and by the said bearings, and a spring interposed between said collars, in combination with a rod connecting said plunger with the grippers, whereby movement of said grippers imparted through the lever will be effected yieldingly in either direction. (45.) In a jack, a movably sustained last-pin, means adapted for clamping the last, and mechanism for forcing a last supported on said last-pin downwardly into operative relation to said clamping-means.
