Abstract

170,813. Anderson, J. April 19, 1920. Gas, supplying by meter; coin-slit closing- devices.-A coin-slit closing device for prepayment mechanism, shown applied to quantity mechanism of the screw-and-nut type actuated by a coin, as described in Specification 170,603, comprises a disc h loose on the axis of the coinpocket and having a slotted flange j, the slot in which is normally held out of register with the coin slot l in the casing to exclude dust &c. by a spring m attached to a pin i carried by the disc h. The slots are brought into register by reverse rotation of the coin-pocket, the pocket acting against a thickened edge of the flange j. When the maximum number of coins are inserted, the nut b engages a lever f and moves it in front of the pin i to prevent the slot l from being uncovered until some gas has been consumed.
