Abstract

508,410. Grinding pen nibs &c. MITCHELL, and BATEMAN, J. March 12, 1938, No. 7764. [Class 60] In a machine of the kind described in Specification 231,646, [Class 60], for grinding pen nibs, &c., the cams a which oscillate the workholders are adjustably and' removably mounted on the shaft b. For this purpose, each cam has a radial slot f to receive the shaft at its inner end, and arcuate slots d, for example, three as shown, through which pass locking screws c engaging flanges e on the shaft b. The slot f is closed at its outer end by a piece g secured by screws h and forming a part of the cam surface. The cams for tilting the work-holders may be formed similarly, but may have the slot f omitted.
