617,307. Locking nuts. UNITED-CARR FASTENER. CORPORATION. Sept. 26, 1946. ,No. 28771. Convention date, Oct. 10, 1945. [Class 89 (i)] Lock nuts have a load carrying barrel 11 and a locking barrel 21, the threads in the barrels being normally out of lead. The barrels are connected by intermediate flanges 13 and 22, 13 having anchoring spikes 14 and 22 being dished and having segmented slits to impart resilience in an axial direction. In a modification the flanges are secured together by spot welding instead of by clinching and both flanges are dished to provide space for an inturned barrel 21, where flush mounting is required.
