Abstract

150,919. Atkins, H. F. Nov. 12, 1919. Turning.-An apron mechanism for lathes having automatic surfacing and traversing feeds has means to prevent the two feeds from being engaged simultaneously and to disengage the saddle in case of obstruction. The worm sleeve b, splined on the shaft a, is moved by means of a pinion r and circular rack h to one of three positions and retained by a spring-pressed stop q. When the latter is located in the groove g the worm c drives the surfacing-screw through the wheel k and pinion l. When the stop is moved to the groove e, the traversing-worm d engages the wheel m, which is solid with a pinion engaging a wheel operating the traversing-feed. The mechanism may be actuated by hand when the sleeve b is in the central position. As soon as the automatic feed is checked, the worm screws out of mesh until the stop regains the central groove f.
