Abstract

1,014,820. Slot cutting. R. WEISBECKER, and G. BARTASONOK. Nov. 6, 1963, No. 43787/63. Heading B3W. A device for widening slots 13 for lock catches and bolts in metal door frames comprises a body 1 having a bolt-shaped cutting tool 5 movable back and forth by a hand lever 12, the tool cutting in the course of its return movement out of the slot into the body. The tool is slidable in a guide 4 in the body and movable by the hand lever 12 which is mounted for movement about a pivot 9 on the body and connected by a bolt 6 to the tool, the bolt being movable along an arcuate slot 6a in the body. The tool has oblique cutting edges on surfaces 5a, 5b, 5c which co-operate with cutting strips 2, 2a secured to the body. In use, the device is held by a handle 11 with the tool extending through a slot 13 and the tool is drawn through the slot by the hand lever 12 so that the cutting surfaces act to widen the slot.
