Abstract: 25,937. Telfer, J. C. Nov. 25. Punching bending. - Relates to machines for setting lacing-devices upon shoe uppers and the like. Individual or gangs of clinchers are used, each having a tapered body a, Fig. 12, a hooked end b, side spurs c, and a finger d with a sharpened spur e. A cast-iron skeleton frame 1, Figs. 3 and 4, secured to a table or work bench, has side walls connected by bridge-plates 2, 4, secured to ribs 3, 5, and bridge-bars 7, 8. The machine is operated by a driving-wheel 20 locked to the driving-shaft 19, mounted in bearing-caps 16,18 connected by bolts and carried by the side walls, by a clutch. This clutch may consist of a bolt 21 engaging a radial notch in the wheel 20 and having a tubular arm 23 pressed outwardly by a spring 24 against a spring-depressed slide 28 having a guide-pin 31 engaging a lug 32. A clutch collar 34 keyed to the shaft 19 has an outwardlyprojecting hub 35 with a quadrant-shaped notch to receive the end of the coupling bolt 21 when released. A plate 37 has a longitudinal slot engaged by a pin 39 carried by a fixed bracket 40, and is raised by a spring 41. This plate has a slot to embrace the hub 35 and carries a cam-plate 43, which, when the pull-rod 47 is depressed, raises the releasing-lip 30 on the plate 28, and a camplate 45 which engages a cam face on the bolt 21 to push it out of action when the rod 47 is raised. A cross-bar 48, having its ends mounted to slide in slots 14 in the frame, is recessed on its inner and unper sides to receive a pair of notched plates 50, 51 and a series of punches 52 clamped in position by bolts 53. The plates 50, 51 are secured to the slide bar 48 by bolts engaging large holes to allow longitudinal and transverse adjustment, which is preferably effected by inverted conical-headed screws or tapered cross-strips engaging wedges with flanges at their outer ends to carry adjusting-screws which also engage the cross-strips and the cross-bar 48. To each end of this bar is pivoted a pitman consisting of a pair of sleeves connected by a double-ended bolt, the lower sleeves being carried by eccentric straps 67 engaging eccentric bosses on the shaft 19. To ensure radial movement and compensate for wear, wearplates 69 are clamped down upon the bar 48 by take-up screws 70 provided with lock-nuts 71. A transverse bar 72, secured in the slots 14, carries a series of parallel arms and a series of parallel ribs 74, a cross-bar 75 being fitted between the two series and having a series of parallel notches 76 and a series of parallel ribs. Die plates 78 are secured between these ribs and have # -shaped openings 79 for the passage of the lacing-devices and the punches. A pair of angle-arms 80 pivoted to the frame and connected by a cross-bar 81 having a forwardly-projecting flange 82 and a series of projecting lugs 83 in the planes of the spaces 76. Arms 84 engage vertical slots 85 in the spring- supported plate 86 which has other notches to register with spaces between the Ings 83 and to receive the arms on the bar 72. The lugs 83 are operated by side handles and serve to raise a gang of lacing-devices into position in front of the punches, a spring-actuated bolt engaging a catch on the bar 72 to lock the bar 81 in position. The waste strip falls to the floor, while the severed lacing- devices are delivered to the feeding-conduits. Bars 93, equal in number to these feed-conduits, rest on the piates 2, 4 and are preferably held in position by set-screws 94, and have hooks 95 to engage grooves in set-screws 96. Sleeves with flanges 100 are fitted in the bars 93 and serve as pivots for bars 101 bearing against the bridge-bars 7, 8, and clamped in position by cam-levers 98. The base portions 103 of standards 102 are screwed to the sleeves through which slide rods 104 grooved at their lower ends to engage slotted yokes 106 adjustably connected to a transverse bar 107 having parallel arms 109 engaging grooved boxes 110 operated by eccentrics 111 on the shaft 19. The bar 107 is adjusted vertically according to the thickness of the stock by wedges 112. Angle-plates 113 fixed to the arms 109 engage the undersides of the eccentrics. The clincher hammers 114 are preferably rigidly secured to the rods 104, and have vertical ribs engaging guide-grooves in the standards 102. The stationary anvils 117 are bifurcated, the longer rear portions having segmental cavities to clinch the spurs e, c of the lacing devices. Reversible anvils 120, Fig. 12, for increasing the bend of the hook b, are carried by shafts 123 adjusted by spring arms 124. One end of an anvil 120 converts the hook into an eye, while the other produces a flat hook. Stop-posts 127, secured to the hammers 114, arrest the lacing devices at the proper positions. Yokes 128, sliding on the rods 104, frictionally grip the sides of the hammers, prevent lateral movement of the lacing-devices, and prevent the stock as it is inserted from coming in contact with the spurs. These yokes are cut away to form one side of a guide for the stock A, the other side of the guide being formed by arms 130 on the hammers. The guide-arms have notches to receive tweezers 132 for retaining the fasteners against the stoppost 127 and gauging the distance the stock is inserted. The tweezers consist of angle-levers pivoted to links 133 and having rearward extensions engaging and operated by slotted cams 136 engaging notches in the hammers and carried by angle-screws 138 engaging sleeves 140 sliding in guide-brackets 141 and reciprocated by adjustable nuts 142 operated by tongs 143. Each pair of tongs consists of a pair of plates united at their ends by an enlargement on a vertical sleeve sliding on a guide-rod 148. Links 151 connect the sleeve enlargements to levers 153 connected to a cross-handle 154 carrying a gauge 155 against which the upper edge of the shoe upper is placed. The lever arms 153 are pivoted at their rear ends to a cross-rod 156 mounted as shown. The lacing- devices are conveyed from the bar 72 by a series of telescopic race-way conduits consisting of troughs 160 pivoted tc a rod 161, on cranks carried by a shaft 163 operated by a handle, and sliding in tubular members 165 hinged at 166 to pins pivoted in sockets in standards 168. When it is desired to make all the lacing-devices of the closed type, the reversible hammer may be replaced by a dished shoulder on the main hammer, and the guide-arm has a gange shoulder above the level of the hook.
