Abstract

230,379. Martens, H. Sept. 29, 1924. Balances and balance springs. - Portable checking and recording clocks for pigeon races are provided with a device for preventing retardation or stopping of the balance wheel by shaking, comprising a spindle 7 rotatably mounted in the framework 4 of the clock, parallel to the spindle 3 of the balance wheel 1 and carrying weighted arms 10. A sensitive spiral spring 8 has one end fixed to the spindle 7 and the. other end fixed to the framework so that when the clock is shaken the weights 10 and spring 8 will cause the spindle 7 to oscillate. A flexible needle 12 fixed to the spindle 7 in the plane of the balance wheel 1 will thus be swung to engage the screws 2 of the balance wheel and accelerate or restart it.
