Abstract
372,475. Locking nuts. NATIONAL SUPPLY CORPORATION, 120, Broadway, New York, U.S.A. March 13, 1931, No. 7822. Convention date, Dec. 26, 1930. [Class 89 (i).] In a rotary welldrilling plant, a ring 23 is threaded to a depending skirt 15 of the rotary table 10 and is held in adjusted position by a lock bar 34 rotatable on a pin 33 threaded and welded to a boss 32 in the ring, the bar 34 being pressed by a spring 35 and engaging, when in locking position, a recess 135 in the boss 32 and one of a series of spaced grooves 136 in the skirt 15. The parts may be secured in this position by moving a nut 37a and washer 36 into engagement with a sleeve 36a depending from the lock bar.
