Abstract

786,746. Machine-tool details. KING (ENGINEERS), Ltd., M. Nov. 11, 1955 [Nov. 12, 1954], No. 32829/54. Class 83 (3). A dividing-head comprises a spindle 2 indexed through a worm 6 and a worm-wheel 5 on the spindle, by a main indexing-mechanism, e.g. an index-plate .8, and an auxiliary indexing- mechanism for moving the worm 6 axially in each direction to further rotate the worm-wheel 5 and thereby modify the main setting of spindle 2 produced by rotating the worm. The latter is keyed at 18 for rotation with the main indexing-spindle 7 and bears in a toothed-sleeve 13 driven by a pinion 20 to displace the worm axially under control of an auxiliary index-plate on the pinion-shaft and a co-operating pointer on the casing 1. Alternatively, the worm may be shifted by a screw-and-fork mechanism.
