Abstract

464,956. Watch balances. JUNGHANS AKT.-GES., GEB. April 8, 1936, No. 10422. Convention date, April 8, 1935. [Class 139] In a balance spring buckle or guard, for covering the free ends of the curb pins so as to prevent the outer coil of the hairspring c from leaving the pins or the next coil from entering, the recess f in the buckle e into which a tool is inserted for turning the buckle is so formed and placed that coils of the hairspring can not be caught up in the recess. In the Figure, a is the regulator arm and the recess is a hole f tangential to the hairspring's outer coil. Alternatively, the recess may be a slot in the undersurface of the buckle for a screw driver, which slot is radial to the hairspring, instead of tangential as in the known art. The outer coil of the hairspring is held between the curb pin d and the main portion of the buckle e which serves as the second curb pin.
