Abstract
491,699. Chucks. CONNOR, J. E. Jan. 22, 1938, No. 2156. [Class 83 (iii)] In a bevel closing chuck wherein the jaws are moved by a conical surface on an outer sliding casing, the means for sliding the casing coact with a stationary member concentric with the chuck and are arranged to hold the chuck in the closed position. The chuck comprises a ring 1 for attachment to a lathe &c. spindle 2 to which is attached a body 3 having three or more radial slots 4 for jaws 5. An outer sleeve 8 has a bevelled portion 10 for closing the jaws and is moved axially by a nut 13 coacting with a screwed ring 11 attached to the stationary headstock 12. A handle 14 for rotating the nut 13 whilst the chuck is rotating may be inserted in one of the openings 15 of the nut and the latter acts on the sleeve 8 through a thrust bearing 16. Springs 6 located in recesses 7 of the body 3 act between projections on the body and jaws to open the chuck. The jaws are held in the slots 4 by segmental pieces 20 attached to the body and having stepped ends 21. A cover 19 is attached to the body and is provided with radial slots for the jaws, which may be shaped as shown at 17. The jaws 5 are tongued and grooved at 18 so that they may interengage when small work is being gripped. In a modification, the sleeve 8 has a bevel 10 of opposite hand on the outside thereof for causing the jaws to expand and grip the work internally.
