Abstract
126,931. Muir & Co., W., Melloy, J. H., and Owen, W. Feb. 20, 1919. Gear-cutting.-In a machine for cutting spur and spiral gears by a reciprocating generating cutter, the indexing motion is performed instantly by dropping the work back at the end of the rolling motion a pitch or more than one pitch during the interval between the cutter leaving the work and re-entering it, in order to avoid any pause in the cutting. The rack-cutter E is carried by a vertically reciprocating slide A. and the work is carried by a table J, which is rotated on a cross-slide H<1>, mounted on an adjustable slide H. The cross-slide H<1> is traversed during cutting by a scroll cam Q on a shaft P acting against a similar fixed cam Q<1> on the slide H<1>, the pitch of the cam Q being equal to or a multiple of the pitch of the gear being operated on. On completion of a revolution of the shaft P, the cross-slide H' is pressed back by spirngs S or other means a distance equal to the pitch of the cam and cutting automatically recommences. The table J is rotated by worm and spur gear from the shaft P, which is rotated by gear L' from the shaft L.
