Title: Improvements in or relating to coin freed apparatus for discharging measured quantities of liquid
IPC: G07F15/00
Filed: 1932-10-31
Abstract: 401,103. Prepayment meters for liquids. BENAIGES, J. B., 3, Calle Garcia Hernandez, and ROSET Y BOES, I., 128, Inmaculada, both in Villanueva y Geltru, Spain. Oct. 31, 1932,No. 30588. Convention date, Nov. 10, 1931. [Class 27.] The apparatus comprises a casing having an inlet pipe 42, Fig. 1, a delivery pipe 35, an hydraulic motor 1 driven by the passage of the liquid, and mechanism for controlling a valve 33, Fig. 4, which closes the delivery pipe. After insertion of a coin, a vertical shaft 13 having an horizontal arm 14 is rotated, and a hemi-spherical roller 15, loosely mounted on the arm 14, travels from a central recess in a disc 6 along a spiral groove in the face of the disc, The groove enters the recess by an inclined portion so that the shaft 13 is raised and opens the valve 33 by engaging its stem 32. As the liquid flows through the apparatus, the motor 1 through gearing 3, 4, 5, 5<1> rotates the disc 6, in the same direction as the shaft 13 was rotated, to return the roller 15. When this reaches the end of the groove, it drops suddenly into the recess to allow the valve to close. The shaft 13 is rotated through gearing 16, 17 from a shaft 18 which is driven through bevel gearing 19, 20 from an horizontal shaft having an outside knob 23, Fig. 2. Coin action, weight; coin-discharging mechanism.-A coin inserted at 36 is delivered to a head 28 on a lever 26, which it tilts to release a stepped cam disc 24, 25 on the shaft 18, the coin being retained on the head 28 by a stop 31. When the shaft 18 rotates, the high portion 24 of the cam disc tilts the lever 26 further to allow the coin to roll off into a moneybox 30. Fraud preventing.-The coin inserted in the slot 36 passes to a slot 39, Fig. 2, in a sliding carrier 36<1>, when this carrier is pressed in, against the action of a spring 38, by a knob 37. On release of the knob 37, the slide 36<1> carries the coin into alignment with the head 28 and the coin drops out of the slot 39 into the head. Light weight coins fail to tilt the lever 26 against the pressure of a spring 29. Too heavy coins tilt it too far so that such coins roll past the stop 31. Registering.-A counter 40 indicates the number of coins inserted. Indicators.-The motor 1 through a gear 4<1> may operate a meter index to indicate the quantity of liquid sold.
