Abstract

1460476 Punching apparatus CARL JIMUKI KK 8 Aug 1974 34935/74 Heading B4B A punch for punching holes in paper and like material comprises a plunger 24 engageable with adjacent ends 20c of two levers 20, which are pivotally mounted at their other ends and engageable with respective punches 16 such that movement of the plunger effects actuation of the punches. The punches are provided with washers 19 screwed thereto and are slidable in apertures formed in base 2 which is secured to a plastics tray 38 having a hinged flap 44 for the removal of waste paper. The levers are formed with flanges 20a which engage in aperture 22 in the base to provide the pivotal connection. The plunger, of plastics material, is provided with a metal insert 26 adapted to engage the levers, and is retained within a cover 30 by shoulders formed on guide lugs 28, Fig. 1; the cover is formed with projections 36 adapted to snap-fit beneath the end walls 8 of the base.
