Abstract
807,344. Prepayment meters. WATT, F. P. May 8, 1957 [Feb. 21, 1956], No. 5257/56. Class 27 A gas or electricity meter has, in addition to the usual total consumption index, an index 44 which cumulatively totals the number of coins inserted so that its indication is ahead of the total consumption indication by the amount of gas or electricity for which prepayment has been made, the index being calibrated in terms of the units of gas or electricty. An inserted coin depresses a slide 34 to cause a pin 35 to move in a slot 36 in a pivoted dog 37 and the nose of the dog engages a toothed wheel 38 on the same spindle 39 as a planet wheel 40. Rotation of a handle 33 will then cause the planet wheel to rotate a sun wheel 41 on a shaft carrying toothed wheels 50 and 42. The wheel 50 drives the index 44 and the wheel 43 drives a wheel 20 connected by a one-way clutch 21 to a shaft 17 having a slow-pitch helix 18, a quick pitch helix 19 and a wheel 16 engaging a worm 15 on a shaft 14 connected to the measuring-out mechanism. Rotation of the shaft 17 one way or the other by the handle 33 or the measuring-out mechanism moves a traveller 24 on a shaft 25 and a stub shaft 26 on tine traveller opens or closes a stop valve in the meter inlet.
