Abstract

142,213. Davey, A. T. H., and Rolls- Royce, Ltd. Feb. 12, 1919. Lathes; tools.-An automatic lathe, having a work turret and a main tool-slide reciprocated by a cam to and from the turret, is provided with an auxiliary tool-slide adapted to carry a two-edged cutting-tool for forming extended recesses in the work-pieces. The tool h is carried in a slide g fed transversely of the work by a lever arc i and rack and retracted by a spring g', the slide being mounted on a carriage f moved along the workpiece by means of a bracket k carried by the main tool-slide a, which also carries the cross-slide actuating cam j, Fig. 1. As the main slide moves toward the work turret, the tool is fed to the required depth by the cam and roller i<3>, and the subsequent axial movement is caused by a boss on the bracket k engaging a nut f<5> on the adjustable rod f<4> attached to the auxiliary carriage f. As the main slide is retracted, the cam leaves the roller, and the tool is withdrawn by the spring g<1>; after retraction, the carriage is moved axially from the work turret by the boss k, engaging a spring f<5> on the rod f<4>, and is stopped by a collar on the rod engaging a fixed bracket e. Any further movement of the main slide compresses the spring f<6>.
