Abstract
745,278. Sawing. CARVER & CO. (ENGINEERS), Ltd., and CARVER, L. J. Nov. 30, 1954 [Nov. 5, 1953], No. 30553/53. Class 145. A machine for cutting two bars 1, tubes or strips disposed side by side comprises a saw 2 or other cutter given an oscillatory or reciprocatory feed motion to cut through first one and then the other and each bar is gripped by a movable jaw automatically operated to grip it during cutting and release it after cutting. Two sets of movable jaws 14, 15 are provided between two sets of fixed jaws 12, 13 and each bar is fed by a slider 4 which has a rubber or other pad 56 and is connected by a cable 5 to one of two pulleys 7 on a shaft 8 rotated by cables 11 and weights 10. A hinged handle 55 can be hooked over the end of the bar support table 3 to hold the slide in inoperative position. The pair of separate movable jaws 14, 15 are arranged to grip the bar on both sides of the place to be cut and the movable jaw 14 that grips the cut-off part may be arranged to release in advance of the other movable jaw so that stock cannot be fed forward until the cutoff part has fallen clear and exposed a feed stop 42. A motor 21 carried by bracket 23 pivoted on a shaft 22 drives the saw 2 and also, through a variable-speed pulley 29, reduction gear 31, crank 33, link 35 and crank 34, oscillates a rock-shaft 28. By means of a crank 27 and link 26, the rock-shaft oscillates the motor 21 so that the saw, operating in jaw gaps 17 and 18, moves backwards and forwards in an arc to cut first one bar and, on the return stroke, to cut the other bar. A pair of cranks 39 on the rock-shaft 28 carry a pin 38 which can engage the tails of jawcarrying levers 36, 37 pivoted on the shaft 22 and, as the pin 38 moves away from the levers for one set of movable jaws 14, 15, to allow springs 41 to move them to gripping position on one bar, it engages the levers for the other set of jaws 14, 15 to release the other bar so that it can be fed up to the stop 42 by its slider 4. The lever 37 for the jaw 15 engaging the stock may have a cranked tail 40 so ;that release of the stock is delayed until the other jaw 14 has released the cut-off part into a shoot 43 or 44. The forward ends of the jaws 12, 15 are shaped to provide leads and the fixed jaws 12, 13 are mounted in a carrier 16 on a platform 47 held in adjusted position by bolts 49 and a clamping plate 50. A coarse adjustment of the end stop may be obtained by adjusting a block 58 along a slot 60 in the carrier 16 and a fine adjustment by means of the screw on the stop itself. The throw, of the crank 27 is adjustable by securing the link 26 in one of several holes in the crank.
