Abstract
531,402. Prepayment meters, SODECO SOC. DES COMPTEURS DE GENEVE. July 20, 1939, No. 21064. Convention date, July 22, 1938. [Class 27] A prepayment meter for electric current supply having a device for computing a fixed charge is provided with a differential gear 6 influenced both by the coin insertion mechanism 12, 13, 14, 15 and by the sum of movements of the electricity meter 7 and of the motor 20 counting the fixed charge. The gear 6 is carried on a frame formed of two discs 1, 2, connected together by pillars 3 and freely rotatable on a shaft 4. The disc 1 is toothed and meshes with a pinion 21 on the shaft of the synchronous motor 20. The gear 6 is carried by a spindle 5 passing through the discs 1, 2, to which spindle are rigidly fixed the pintle carrying the spider pinion 9 and a pinion 11 driven through gearing by the meter 7. The coin knob 12 is geared to a wheel 17 fixed on the shaft 4, and transmits its motion to the sun wheel 16 by way of a wheel 18 fixed to shaft 4 and a pinion 19 fixed to a sleeve carrying the wheel 16 and riding freely on the spindle 5. The sun wheel 24 transmits its motion by way of pinions 23, 25 and 26 to a switch cam 22.
