Abstract

763,017. Locking screws. ENGLISH ELECTRIC CO., Ltd. May 27, 1955 [June 3, 1954], No. 16450/54. Class 89 (1). A screw 6, Figs. 1(a 1(b), is locked against rotation relatively to a plate 7 by a helical spring 10, of opposite hand to the thread of the screw but of substantially the same pitch and closely fitting the screw, locking being effected by turning the spring ends 10a, 10b to tighten the spring about the shank and then retaining the ends fixed relatively to the plate. The plate is provided with a projection 11 against one side of which abuts end 10a. On tightening the spring, end 10b is moved to engage the other side of the projection as shown in Fig. 3(a). In its untightened condition, the spring consists of one and one quarter turns, and the ends extend tangentially therefrom at right-angles to one another, Fig. 1a.
