Abstract

534,241. Winding-mechanism. GOLDSMITHS & SILVERSMITHS CO., Ltd., and CARLE, D. DE. Oct. 2, 1939, No. 27039. [Class 139] Comprises a winding mechanism for watches wherein the winding or barrel ratchet wheel a is freely mounted and has associated therewith or accommodated therein a spring ring e forming part of a friction drive between such winding wheel a and the main spring winding mechanism. The ring e has a notch f in which engages a lug g on a boss h also carried in the recess c which houses the ring e and mounted on the squared barrel arbor i connected with the main spring winding mechanism. The wheel a is mounted loosely on a spigot k of the boss h. During winding from the usual knob through a gear b the ring e exerts a greater resistance than the main spring, but when the latter is fully wound, the ring e slips.
