Abstract

955,375. Clocks and watches. R. A. SMITH, and C. A. SMITH, [trading as SHIELD WATCH CO]. Feb. 12, 1963 [July 7, 1962], No. 26146/62. Heading G3T. A watch or clock balance and balance spring assembly, of the kind wherein the inner end of the balance spring 5, which is of the flat volute type, is attached (such as by a collet) to the balance staff 3, and the outer end is anchored to a fixed stud, and wherein the key of a regulating lever engages the outer coil of the balance spring, is provided with a disc-like shield or guard 4 of a diameter approximately equal to that of the flat volute-type spring, this shield or guard being a separate part surrounding the balance staff and mounted on and secured to the usual arms 2 of the balance so as to be located between said arms and the spring. The device ensures that under the effect of shock, the inner coils of the spring do not deflect unduly and hence do not rebound so as to be caught' or hooked up on the stud or the key of the regulator.
