Abstract

259,735. Timson, A. R. Sept. 14, 1925. Rotary punching-machines.-Punches 9, Fig. 2, are secured by plates 16 to blocks 5 circumferentially adjustable in a carrier disc 1. Holes 18 are provided for the punchings. Studs 8 secured to the blocks pass through slots in the disc 1 and are secured in position by nuts 7. The punches co-operate with a disc 10, Fig. 3, on which a covering strip 19 is secured by a block 21, with pins 22 engaging the holed ends of the strip. The strip is tightened by a screw 24 and nut 25. The punches may be fitted for independent or group adjustment.
