Abstract
562,905. Grinding machines. MARTIN, BLACK & CO, (WIRE ROPES), Ltd., and McPHERSON, A. Feb. 5, 1943, No. 1931. [Class 60] A machine for grinding conical surfaces, particularly the needles used to form the central holes in wire-drawing dies, comprises a rotary work holder which can be angularly set with respect to the grinding wheel and traversed parallel to the wheel axis, the traversing motion effecting a feed having a cut-out operated at the end of the grinding operation. The grinding wheel 10, Fig. 1, is adjustable vertically and is driven from the motor 14 which also drives a shaft 22 from which the work holder 18 is driven. The work holder is adjustable about a transverse axis and is carried by a slide 27 which is reciprocated by a cam 31 driven from the shaft 22 by bevel and worm gears. The work holder derives a feeding motion from a feed screw 38, Fig. 3, fixed to the slide 27 and a feed nut 39 journalled in a yoke 41 forming a support for a bracket 26 carrying the work holder. The nut 39 is fitted with a ratchet engaged by a pawl 42 as the slide reciprocates. An indicator nut 45 turns in unison with the ratchet on a non-rotatable threaded tube 48 and carries a scale 45A. The pin 46 is adapted to operate a shroud 50 for the ratchet to stop the feed at the end of the operation.
