Abstract
388,690. Timepieces. MADER, D. H. and KAUFMANN, M. A., (trading as MADER & CO.), Chezard, Neuchatel, Switzerland. Sept. 20, 1932, No. 26115. Convention date, Sept. 23, 1931. [Class 139.] Winding - apparatus.-In a self-winding timepiece the oscillations of the movement 1 relatively to a stationary support 3 rewinds the mainspring, a shaft 11 rotatably mounted in the movement being provided with a crank 12 carrying a pawl 14 which drives a ratchet 17 of the winding train, links 5 being fixed to shaft 11 and pivoted to member 3 to allow oscillation between parts 1 and 3. A second pair of links 4 is pivoted to the case 2 and to the support 3. The latter has loops for the wrist strap 6, the portions 20 of which act as shock absorbers for case L. A spring 19 keeps pawl 14 in engagement with ratchet 17. The invention is also applicable to automobile clocks.
