摘要： 583,195. Rolling annular bodies; screwing; chucks. BRASSERT & CO., Ltd., H. A., UDALL, W., and WEEKS, W. A. June 16, 1944, No. 11545. [Classes 83 (iii) and 83 (iv)] Relates to the rolling of annular bodies as described in Specification 583,187 and consists in means for opening and closing the segments of the outer roll without stopping rotation and for closing and opening the pass. The segments 2, Fig. 2, are located by dowels 5 in holders 4 in which they are secured by cotters 3. Shanks on the holders are guided in the legs of a spider 6 and carry rollers 10 engaging in cam slots 11 carried by a housing 12 secured to a sleeve journalled in a bearing 13, Fig. 3,.in a mounting 14 carried by a head 15 rocking in bearings 21 in the frame. The spider is secured to a sleeve 8 journalled in the housing sleeve and in a bearing 17 and carrying a brake drum 20. The housing sleeve is driven at 24 from a shaft 27 carrying a brake 29 and electromagnetic clutch 31. The segments are opened and closed by causing rotation between the sleeve 8 and housing 12 by manipulating the clutch 31 and brakes 29, 20. The ring blank to be rolled, mounted on the divided internal roll 1 as described in the prior Specification and held by the segments 2, is rolled out by-rocking the frame 15 by means of a driven cam 40. - Automatic controls for the clutch and the brake solenoids may be synchronized with the camshaft 41. In a modification, the parts 8, 12 have independent drive and brakes so that each part may be controlled independently of the other and the two may be looked in any desired relative angular positions.' Screwing die-heads; chucks.-The roll segment opening &c. mechanism is stated to be applicable to chucks, screwing-dies and holders for taps and dies.
