Abstract
174,504. Williams, E. Nov. 30, 1920. Driving and feed devices. - Change-speed gearing for a grinding-machine headstock comprises a driving-shaft a carrying slidable pairs of gears e, f engageable with fixed pinions to impart four speeds to a shaft b, which carries also loose gears n, m in constant engagement with a compound wheel o, p slidable on a fixed countershait q and a loose gear v engaging a wheel r on the spindle. The compound wheel is moved by means of a feathered clutch member s, which for forward running is engaged with the loose gear n. The wheel v may then be engaged with either of the gears n, m to transmit in all eight spindle speeds. For reversing, the wheel p is engaged with a pinion y on a reversing-shaft w driven at four speeds from the wheel i on the shaft b, and, by engaging the pinion v with the gears n or m, eight reverse speeds may be obtained. Specification 22115/14 is referred to.
