Abstract
1356095 Boring holes in sheet material; punching P MALARD and D MALARD 15 Feb 1973 [18 Dec 1972] 7551/73 Headings B3C and B3W Apparatus for punching or boring holes in plates comprises a body 1 having a cylindrical bore in which a plug 2 can rotate and slide, the front edge thereof is connected to a cap-shaped tool 3 with a toothed edge, a guard plate 12 is positioned to clamp a plate to be punched between the body and itself, and means operative between the guard plate and the plug to move the plug and the tool toward the plate. The body 1 has a stirrup 6 at its rear end. A shank having a threaded part 8 and a thinner part 9 is mounted between the stirrup and the guard plate. A nut 31 can be rotated to move the plug axially against the action of spring 25. A handle 36 can rotate the plug in one direction only by means of pawl 39 and grooves 38. The plug is drivingly connected to the tool by a rib 21 and groove 22 connection. A bearing plate 15 helps guide the tool 3. For operation on a thin plate nut 31 is rotated to push plug 2 and thence tool 3 through the plate and thus punch a hole. On a thicker plate lever 36 is rotated at the same time which causes the tool 3 to rotate. Sets of tools, bearing plates and guide plates may be provided for different diameter holes.
