Abstract

454,170. Perforating-devices. SPEKE, G. V., 23, Cecil Road, Muswell Hill, London. April 3, 1935, No. 10350. [Class 31 (ii)] A device for perforating sheet material comprises a base 5 having two sheet metal standards 9 which slidably support two punches 18 and are provided with upstanding ears 15 having inclined slots 25 in which bear pivot pins 24 of a forked operating lever 20. The punches are raised by springs 23 and pass through bosses 19 on the lower plates 12 of the standards 9. The position of the work is determined by a slide 34 having an upturned end 36 and split at 35 to provide a frictional grip ; the slide may be further held by a cam surface on a lever 39. The waste material is received in a tray 27 having an inclined inner end 29. Rubber feet 38 may be provided on the base 5.
