Abstract

241,211. Soc. Franþaise de Filetage Indesserrable D. D. G., (Assignees of Dardelet, H. L.). Oct. 9, 1924, [Convention date]. Screw-and-nut mechanism.-A self-locking nut and bolt a, b for use in clamping together parts c, c, is so constructed that the tangent of the angle a which the bearing face of the thread makes with a parallel to the axis in a plane pass ing through the axis of the bolt is less than the coefficient of friction of the metals in contact'. The pitch of the thread is made correspondingly great, and in the limiting case is infinite as shown in Figs. 3 and 4 in which the thread constitutes a projection r<1> parallel to the axis of the bolt. In this case, the bolt is turned relatively to a fixed nut a<1> to obtain a locking effect. Specification 239,486, [Class 89 (i), Bolts &c.], is referred to.
