Abstract

880,001. Screw and nut gearing. BISHOP, R., JOHNSTON, R. H., and WHITLOCK, G. B. R. Dec. 4, 1957 [Dec. 7, 1956], No. 37534/56. Class 80 (3). In screw and nut mechanism having balls 4 between the screw 1 and nut 2 the balls circulate in one or more separate helix turns whose ends are connected by S-shaped cross-over channels 15 provided in a key 3 which is inserted in an axial groove in either the screw or nut, the balls being thus rolled over the land of the thread in either the nut or the screw. The key 3 may be secured in the axial groove but is preferably a loose sliding fit therein. The two ends of each channel 15 extend in the direction of the threads with which they register the intermediate part of the channel being arranged at right angles to this direction. Where more than one channel 15 is provided, they are spaced by at least two pitch lengths. Specifications 880,002 and 880,003 are referred to.
