Abstract

566,104. Turning. MOORE, C., and WESTBURY, E. T. Aug. 18, 1943, No. 13412. [Class 83 (iii)] In a turret attachment for a small lathe, a selector stop bar is secured to a shaft which is rotated intermittently by the turret through pins on the lower face of the latter engaging recesses in a polygonal prism attached to the shaft. The turret A is rotatable on a stud B attached to the slide C which is traversed along the lathe bed D by a hand lever N pivoted at N<1> on the bed and engaging a pin N<2> on the slide through a tumbler N3. The selector stops H are carried by a disc H<1> mounted on a shaft G rotatable in the slide C and carrying a prism J having as many sides as there are tool stations in the turret. Normally, one of the flat sides of the prism lies against the base of the turret to lock the stop disc against rotation, but when the turret is rotated for indexing, one of the pins E arranged in a circle on the turret base engages a recess J<2> in the prism to rotate it and index the stop disc, cavities A<1> being provided on the turret base in line with the pins E to clear the corners of the prism. The turret is indexed by a pawl L engaging a ratchet M on the base of the turret, the motion of the pawl with the slide C during its rearward traverse being prevented by a rod K engaging a fixed stop. The rod K may be returned on the forward traverse by a spring K<1> or may be attached to the stop for positive action in both directions. An index bolt O in the slide C is withdrawn from a recess O<1> in the turret against spring pressure, prior to indexing, by a bell-crank lever P pivoted on the slide engaging a fixed cam R during the rearward traverse. Lost motion is provided between the bolt O and lever P so that the latter may ride over the reverse side of the cam R during forward traverse of the slide.
