515,929. Lock nuts. GUEST, KEEN & NETTLEFOLDS, Ltd., and WHITCOMBE C. J. Aug. 15, 1938, No. 23955. [Class 89 (i)] A lock nut is formed at one end with one or more integral segments 14 each partially severed from the out body by a slot 12, preferably at right angles to the axis of the nut, which extends through the thickness of the wall of the nut and partially around the circumference thereof and to one end of the nut, the thread of the nut extending through said segments which are integrally connected to the nut at the end which leads when the nut is screwed on to a bolt or the like, but are distorted after threading by bending in a direction parallel to the axis towards, and preferably into contact with, the body of the nut. The open end 13 of the slit may extend axially, and one or more of the segments may also be bent inwardly towards the axis. The main body 10 of the nut may be polygonal and of standard thickness and the segments 14 cut in a cylindrical extension 11 of a diameter slightly less than the distance across the flats of the nut. When two distorted segments are provided, the end slits 13 are in alignment with each other and may be arranged at the ends of the slits 12 or intermediate said ends.
