Abstract

606,905. Securing washers against loss. EVERY. C. E. (Crowther, E. C.). Nov. 6, 1945, No. 29570. [Class 89 (i)] A combined screw and washer, more particularly for clamping thin material, has the washer of conical form with a larger included conical angle X than the standard. The washer is of thin stock and is prevented from unscrewing from the screw by increasing the effective thickness of the inner edge 30 by corrugating or flanging. Locking.-The outer edge may be flat as 28 or may be formed into locking-teeth.
