Abstract

712,615. Pliers for punching holes in sheet material. MACLEAN, T. T. Jan. 8, 1952 [Jan. 10, 1951], No. 690/51. Class 61 Pliers for punching holes in thin sheet material comprise a punch member adapted to be rotated while being caused to penetrate the sheet member. The pliers comprise a pair of pivoted arms 10, 11, the head of the arm 11 having attached thereto a small cylinder 13 and anvil piece 14. A punch member 15, the outer surface of which has spiral flats 16, is located within the cylinder and engages a correspondingly shaped hole 17 in the base thereof so that when the punch member is depressed it is rotated by engagement of the flats with the sides of the hole. The punch is operated by the nose 21 of the arm 10 a return spring 20 being provided. A hollow punch member 15 is shown having a knife edge 18. In a modification, a solid punch member is provided. A guide for spacing the holes from the edge of the material, Fig. 7, comprises a right angled bracket, the horizontal arm 25 of which is adjustably secured to the underside of the anvil jaw by a screw 27. Gauges 32 for spacing the holes from each other comprise right angled brackets the vertical arms 33 of which are adjustably secured to side extensions of the vertical arm 28 of the bracket.
