Abstract

387,133. Self-locking nuts and bolts. KIELLAND, J. DE R., 6, Ivar Aasensvei, Vinderen pr., and STANGE & CO. AKTIESELSKAP, H., 2, Karl Johansgate, both in Oslo, Norway. Feb. 11, 1932, No. 4136. Convention date, May 27, 1931. [Class 89 (i).] A combination of nut and bolt has one member normally threaded, while the thread of the other member has a profile formed by the superposition of two, three or four normal thread profiles having different bottom diameter and being axially displaced with regard to each other by a fraction of a full pitch of the thread, whereby one or more stepped surfaces are obtained on one side of the modified thread. The ridge 5 between the bottoms 3, 4 of two displaced threads may be rounded off.
