Abstract: 114,472. British United Shoe Machinery Co., (United Shoe Machinery Co.). April 4, 1917. Setting eyelets.-A machine for setting eyelets and lacing-fasteners is provided with improvements in the mechanisms for operating (1) the lower eyelet-carrying set, (2) the upsetting and punching tool, and (3) the raceway for supplying eyelets. Setting-mechanism.-The lower setting-tool 9 is mounted on a plunger 6 oscillated by means of the mechanism, shown in Fig. 2, comprising a. lever 14 pivoted at 16 and having, at one end, a jaw in which works a block 10 pivoted to a collar 8, and at the other end, a curved slot 18 in which works a curved block 20 driven by a crank 22 on the shaft 4. This construction causes the tool 9 to move rapidly when near the top and slowly when at the bottom of its stroke. The upper seting-tool 40 is mounted on a plunger 34 which reciprocates in a frame 32 supported for lateral oscillation by a fixed rod 26 and sliding rod 28. A collar 36 detachably secured to the plunger rests upon an adjustable nut 38, and is pivoted at either side to links 42 which form the lower members of a pair of toggles, the upper members of which are formed bv the limbs of bell-crank levers 44. The other limbs of the levers 44 are slidably pivoted on a rod 43 secured in a link 48 having an inclined slot 50 therein through which extends a pin 52. The link 48 is oscillated by a lever 54, Fig. 4, pivoted at 56 and actuated by a cam 58 on the shaft 4. Work-feeding mechanism.-For the purpose of transversely oscillating the tool 40 to feed the work, the frame 32 has pivoted thereto a block 80 slidable in the jaw of a forked lever 82 journaled on a stationary shaft 86, and engaged between ears 84 provided with adjusting screws secured to a sleeve 88 having integral therewith an arm 90 connected to a link 92 pivoted in turn to a link 94. The link 94 is pivoted to a yoke frame 98 guided for horizontal movement and oscillated by a cam 100 on the shaft 4 rotating between its jaws. Eyelets, feeding.-Eyelets are supplied to the spindle of the tool 9 by a raceway 120 removably secured to a bracket 122 pivoted on a shaft 124. Movement of the raceway is effected by a crank 136 on the shaft 4 connected through a link 134 with a pivot on an arm 132 which is connected at its lower end through a universal joint to an adjustable pitman 130 similarly connected at its other end to one arm of a bell-crank lever 128, the other arm of which is connected by a short link 126 to the bracket 122. A hopper of ordinary type is connected to the raceway. Work-holding mechanism.-The work table 71 is perforated to permit the passage of the tool 9 and carries a cutting-bed 69. A presser foot 72 is adjustably clamped to a rod 70 to which is secured a block 68 carrying a roller 66 raised intermittently by a cam-plate 64 against the pressure of a spring. The cam 64 is oscillated about an horizontal axis by a rod 62 connected to a jaw of the lever 54. The rod 70 carries a lever 74 by which the rod may be raised to release the foot 72. To regulate the spread of the eyelets or their distance from the edge of the lacing slit, a gauge 160 is adjustably secured to an arm 162 pivoted on the work-table and adapted to be clamped thereto by a nut provided with a handle 166. Specification 13084/99 is referred to.
