Abstract
564,023. Clock systems. LANDIS & GYR SOC. ANON. June 29, 1942, No. 8918. Convention date, July 31, 1941. [Class 139] A clock installation including a series of impulsedriven secondary clocks has two or more master clocks, one of which is provided with regulating. mechanism while the others are synchronized by means coupled to the said regulating mechanism. As shown in Fig. 1, two master clocks 1, 1<1> are arranged in a casing 6 with a set of secondary indicators 5. The clock 1 includes an inductor 2, a driving weight 3 and regulating pendulum 4; the clock 1<1> <1>is similar except that it has no regulating pendulum. The anchor or pallet shaft of the escapement wheel of the clock 1 is provided with an arm 7 which is connected by a rod 8 to a similar arm 7<1> of the clock 1<1> so that the shafts move in unison. The form of connection is shown in Fig. 3, the rod 8 having rounded end points 9 which rest in a bearing cup 10. Pressure is adjusted by means of a spiral spring 11 threaded on a setting ring 12 on the rod 8 and on a bolt 13.
