Abstract

423,340. Locking-bolts. PLACE, C. E. S., Port Chester, New York, and WINKLE, M. VAN, One Exchange Place, Jersey City, New Jersey, both in U.S.A. June 9, 1934, No. 17163. [Class 89 (i)] A bolt or cap screw is made self-locking by providing its head with a centrally-disposed bore 8 and its under surface with an annular bearing- surface 11 spaced from the shank 5 by the annular recess 10. The depth and diameter of the bore is such that the annulus 13 left between it and the groove 10 is dimensioned to act as an elastic diaphragm to produce the desired locking effect when the bolt is screwed up.
