Abstract

164,419. Fairbank, H., and Barron, C. H. Feb. 4, 1920. Locking nuts. - A pivoted spring-controlled' pawl C, Figs. 1 and 2, is inserted in a slot in a nut A and is provided with a nose C' preferably formed to engage the bottom of the thread of a bolt and to form a cutting angle to dig into the material of the bolt upon reverse rotation. This nose lies only a little to one side of a line connecting the pawl pivot and the centre of the bolt. One part C<3> of the pawl may project beyond the side of the nut for actuation by a spanner to release the lock when it is desired to unscrew the nut. A grub screw or equivalent E with a conical point is arranged to act on a horn of the pawl to effect release of the lock. Two pawls acting in opposite directions so as to lock the nut against movement in either direction may be employed.
