Abstract

648,586. Prepayment meters. PARKINSON & COWAN (GAS METERS), Ltd., ROLFE, L. H., and DOUGLAS, R: R. R. Nov. 17, 1948, No. 29885. [Class 27] Multiple coin with delivery proportionate to value of com.-A coin freed mechanism for a gas or similar meter embodies two epicyclic gears with a common planet carrier, one planetary system acting in a direct step up or down capacity for a coin of one denomination, and the planetary systems of both epicyclic gears acting for a coin of another denomination. As shown in Fig. 1 insertion of a coin of a higher denomination provides for the rotation of a coin wheel 5 connected to a sun wheel 18. The sun wheel 18 is connected through integral planet gears 16, 17 on a planet carrier 11 to drive a sun wheel 19 on a bush 20 operating a gas valve. A coin wheel 6 for a coin of a lower denomination is connected to a sun wheel 10 meshing with a planet wheel 12 on the planet carrier 11. The planet wheel 12 meshes with a further planet wheel 13 which meshes with a sunwheel 14 on a bush 15 driven from a meter.
