Abstract
126,930. 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 cutter 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 in the saddle C, which is traversed across the ram slide A during cutting by a scroll cam Q on a shaft P, acting against a similar fixed cam Q<1> on the saddle, 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 saddle C is pressed back by springs S or other means a distance equal to the pitch of the cam, and cutting automatically recommences. The shaft P is rotated by gear 0 from the shaft N and the work-carrying table J is rotated on the adjustable slide H by wormgear K and change-wheels M through the shaft L.
