Abstract
1316392 Electric watches TIMEX CORP 20 July 1971 [20 July 1970] 34068/71 Heading G3T [Also in Division H1] A contact spring assembly for a timepiece including an electromagnetically-maintained balance 10 carrying a coil 14 comprises a base member 22 of insulating material, a conductive contact-supporting member 23 embedded in base 22 and extending outwardly therefrom, a contact spring 28 having a free end and being mounted to the member 23, and a damping material 32 within which a portion of the spring 28 is embedded to minimize the vibrations thereof. As shown the free end of the spring 28 co-operates with a pin 18 and jewel 19 and its other end is soldered to an upturned end 27 of extension 26 of member 23. The base 22 is of plastics material such as polyester fibre-filled diallyl ortho-phthalate resin and a protruding portion 29 is slotted at 31 to hold the damping material 32, for example, a urethane plastics material, which is preferably deposited as a liquid and then cured. A U-shaped extension of member 26, Fig. 3 (not shown) may replace portion 29 or the damping material may be coated around the end of spring 28 in the region of 27 without other support.
