Abstract
851,142. Clocks and watches. KIENZLE UHRENFABRIKEN A. G.. Dec. 18, 1957, No. 39322/57. Class 139 In a timepiece, the outer end of the hair spring is fixed in a slot in the stud in a strain-free manner. In the first example, Fig. la, the outer end of the hair spring 5 is freely located in the slot 3 of a stud 2 fixed to the balance cock 1. The screw 4 is then rotated to narrow the slot 3 and so grip the hair spring. The slot 3 may be formed by the space between the stud 2 and the head of a screw which is locked against rotation. The outer end of the hair spring 5 may be located in a slot formed by the space between the eccentric head of a pin secured against rotation by a spring 8, Fig. 3a. In another example, Figs. 4a, 4b, a stud 9, 12, 13 is fixed to the balance cock and is prevented from rotating by a pin 14. The outer end of the hair spring passes through a hole 10 in the stud and is secured therein by a hardening medium e.g. an adhesive, a cement, a solder or the like.
