Abstract
772,940. Watches. LAISNE, A. A. E. Oct. 20, 1955, No. 29976/55. Class 139. The crown 1, Fig. 1, passes through the pendant tube 7 and carries a pin 5 which engages a slot 6 in the winding stem 2. A spring ring member 11 located in a groove 12 in the pendant engages a projection 10 of the crown 1 which is thereby urged downwardly to compress the packing 9 against the bottom of the pendant. A washer 14 retains a second packing 3 in position. The play between the pin 5 and the slot 6 allows of a slight inward movement of the crown 1 from the position shown and additional compression of the packing. In a modification in which the pendant is cylindrical the spring member is located in a groove in the case. The crown may be connected to the winding stem by the form of joint shown in Fig. 3.
