Abstract

213,952. Pearn, W. A. Dec. 15, 1922. Turning.-In gearing as described in Specification 19159/12 for rotating the mandrel of a boring and facing machine, a four speed arrangement is converted into a five speed arrangement. A pulley a, driven by a belt from a gear box in the base of the machine, is secured to a sleeve b which drives a gear wheel o on the face-plate through a counter-shaft irom which four speeds are obtainable, the fifth speed being derived by locking the pulley to the mandrel c carrying the face-plate by means of a plunger e. Specification 25589/99 also is referred to.
