Abstract

944,210. Punching-machines. KERSHAW & ROCHE Ltd. Oct. 31, 1962 [Nov. 4, 1961], No. 39552/61. Heading B4B. In a punching machine in which a row of spring-loaded punches operable by means of a pivoted hand lever 13 are slidable in a head portion 5 overhanging a bed 7 and providing a stop for the edge of a sheet of paper or other material to be punched, die-holes 9, 9a in a bed 7 open into a waste-receiving cavity 27 provided in the underside of a base 17 and normally closed by a slidable plastic cover-plate 25 having a hole therein engageable with a projection 31 on a wall 23 of the base. A wall 22 and lateral ledges 24 of the base are rebated to receive the edges of the panel 25 which is retained by cover strips 26 fixed to the base. The head portion 5 comprises two blocks 6, one of which carries a punch 8 for actuation at each downward stroke of the lever 13 whilst the other carries two punches 8, 8a, either of which is operable, through the medium of a selector member 15 pivoted on the lever, when the latter is depressed. The distance of the punches from one end of the sheet to be punched is determined by means of a stop 21 provided on a gauging bar 19.
