<p>1,044,293. Ratchet clutches. TORRING- TON CO. Feb. 28, 1963 [March 1, 1962], No. 19995/66. Divided out of 1,044,292. Heading F2C. A one-way jamming roller clutch comprises a thin outer shell 8 having a cylindrical external surface and a cam-pocketed internal surface, the shell being press-fitted in a gear or pulley housing and, during clutch engagement, being expanded by roller wedging action to increase the pressure between the shell and its housing and thereby increase resistance to relative rotation thereof. The shell may have integral inturned roller-retaining end flanges one of which is inwardly turned after assembly of a cage 9. Alternatively, separate roller-retaining rings may be received in internal grooves in the shell.</p> |
