Abstract

206,627. Smith & Coventry, Ltd., and Wright, I. H. Sept. 9, 1922. Lathes. - In a brassfinishers' or like lathe, the handle a, by which the holder c secured to the sliding bar n is swung to disengage the segmental nut q from the lead screw p, is also connected through a shaft d and gearing e to the tool-adjusting spindle g. The position of the tool-slide b may thus be set by rotary movement of the handle a. For cutting duplicate work-pieces the spindle g may be locked in position by an adjustable abutment-screw j. The usual lever m may be employed to give the initial movement to disengage the tool from the work.
