Abstract: 115,483. British United Shoe Machinery Co., (United Shoe Machincry Co.). May 8, 1917. Socks, securing.- A machine for past-. ing sock linings in boots and shoes comprises . a turret 3 having a number of radiating arms 3', Fig. 1, each carrying a pair of hoppers 4 containing linings for right and left shoes; the linings are supported by bottom flanges 5, 6, Fig. 14, and are pressed down in their magazines by followers 8, Fig. 1. The shoe is supported on a troughshaped jack 65, and, after the turret has been. rotated to bring the correct hoppers into operative position, the main shaft 14 of the machine is thrown into gear. The various parts are actuated from cams on the shaft 14, which is controlled bv a one-revolution clutch. A carrier 9 is moved forwards causing a spring-pressed holder 15 carrying a hook-shaped picker 17 to contact with a cam surface on a bracket 20 so that the picker 17 engages and draws the bottom lining of the stack downwards and forwards from the hopper and into the jaws 49, 50 of a gripper, the rod 45 of which is mounted in an arm 33. This arm is then swung downwards about a shaft 34, and, as soon as its movement is started, the tail 52 of the jaw 50 is moved from beneath a trip pin 53 and the jaws 49, 50 are closed by a spring. The gripper then draws the lining completely from the holder, the rest of the stack being meanwhile supported by a reciprocating finger 22, and carries it downwards between curved plates 63, and an intermittently rotated paste-applying roll 57, which is loaded from a receptacle 56. The lining is then drawn over a guard-plate 64 for the upper and down into the shoe, against which it is pressed by an outward movement of the gripper caused by the engagement of a pin 54 with a cam face 55b on an arm 55. A lever 66 is then swung downwards) to cause a pad 70 on a flevible rod 69 to engage the heel end of the lining and to press it against the shoe, Fig. 9. Downward movement of a lever 72, Fig. 1, then causes a rod 74, Figs. 1 and 9, to open the jaws 49, 50, allowing the gripper to be withdrawn, alter which a brush arm 75 is swung forwards to sweep the lining down flat on the shoe bottom. The picker 17 is suitable for linings of textile material, but for linings of leather, imitation leather, &c., a picker of the forms shown in Figs. 15 and 18 is preferably used. This comprises a series of short needles 98 projecting from a head 97<1> removably secured to a finger 97, which is mounted on a pivot 96 projecting from a spring-pressed sleeve 92 slidably mounted on a post 91 rising from a reciprocating carrier 90. As this carrier moves forwards, one end of a cam lever 100 engages a fixed roller 102 and causes the other end of the lever, which bears against the curved face 99<1> of a lug 99 on the finger 97. to raise the finger so that the needles 98 pierce the lining. A pin 106 then meets an inclined face of a bracket 105 and causes the finger to swing forwards and downwards on the pivot 96, so that the lining is moved into the open jaws of the gripper.
