Abstract
779,934. Clocks and watches. JORIOT, C. Aug. 30, 1955, No. 24920/55. Class 139. The rim of the balance 1, Fig. 6, has a peripheral groove 21 in which four curved weight members 16<1>, 16<2>, 16<3>, 164, are adjustably located. The members 16<1>-16<4> pass through holes 17, Fig. 7, in the heads 19 of screws 18 screwed into the balance. The balance cross arm 1, Fig. 1, is located on the arbor 9 at one side of a collar 10 and is attached by screws 5<1>, 5<2> to the double roller 5. A resilient washer 11 is located in the counterbore 7 of the roller 4 which has an extension 14 to counterbalance the pins 12, 13, Fig. 3. In another example, Fig. 11, the roller 4 is forced on to a tapered section 52 of the balance arbor 9. If desired the balance cross arm 1, Fig. 13, may be located by pins 42<1>, 42<2> on the double roller and the assembly fixed to the balance arbor by riveting at 47.
