Abstract

217,755. Coppard, G. R. June 5, 1923. Attachments for milling.-An attachment for a drilling-machine to enable slots, keyways, &c. to be cut, e.g. the slots in the stems of mushroom valves for internal-combustion engines, comprises a block 3 in which is mounted a hardened interchangeable screwed bush 18 bored to receive the cutter, and a work-holder 1 having a V-groove 6 in which the work is clamped by a strip 7. The. work-holder carries strips 4 which overlap the block, and is adapted to be traversed between guides on the machine table by a, screw 22 engaging the block and journaled at 23. Adjustable stops 11, 14, locked by a screw 12 and a nut 16, limit the travel of the work. A slot 21 in the holder and a recess in the block allow cuttings to escape and give clearance for the end of the cutter. According to the Provisional Specification, the work is clamped between two blocks slidable in V-grooves in a base plate, the top block having the cutter-guide slidably mounted therein.
