Abstract: 987,759. Dispensing liquids. TOKHEIM CORPORATION. Sept. 11, 1961 [Sept. 12, 1960], No. 32591/61. Heading A4T. [Also in Division F1] An installation for dispensing measured quantities of liquids, e.g. petrol, comprises a liquid discharge pipe with a valved outlet, a pump for supplying liquid under pressure to the pipe, a meter for measuring the amount of liquid flowing through the pipe, a register for indicating the amount of liquid dispensed, hydraulic motion-transmission means for driving the register from the rotation of the shaft of the motor when liquid is passing through the pipe and valved outlet. The register may be situated at a point remote from the point, e.g. a petrol filling station, where the liquid is dispensed. The petrol filling station shown in Fig. 1 comprises an underground petrol storage tank 5, a motor pump 7, with a motor 8 mounted thereon and pumping petrol through a gas separator in a header 11 to meters 19 and 21, each of which is connected to one or more registers and a dispensing unit, as shown the meter 21 is connected to two registers 129 and 131 and a dispensing unit 105. The unit 105 comprises a flow control valve 29, a hose coiled on a spring-loaded drum in a pit 35 and withdrawable therefrom through an opening 127 defined by rollers 125, a nozzle 39 and a lever 121 rotatable with a shaft 83 clockwise and counter-clockwise when the nozzle is lifted from its support to start and finish dispensing respectively. Rotation of the lever 121 serves to start the motor and operate a pilot valve 43 (not shown) which controls the flow valve 29. Each register 129, 131 is of known type and has a driven shaft 133 driving a gallons counter 135 and through a manually adjustable variator 137 a cost counter 139. The resetting mechanism for the registers comprises a unit 143 (not shown) of known type which is tripped by rotation of a shaft 147. At the end of a dispensing operation the shaft 147 is rotated in the reverse direction to condition the mechanism 143 for a subsequent resetting operation. The shafts 133 and 147 are driven by hydraulic motion transmission systems (see Division F1) from the meter 21 and the shaft 83 of lever 121. As shown the meter 21 is arranged to drive a shaft of a liquid displacement unit 153 which is combined with identical liquid displacement units 153<SP>1</SP> and 153<SP>11</SP> arranged to drive the shafts 133 of registers 129 and 131 respectively. The hydraulic motion transmission system for operating the resetting mechanism 143 also serves to operate the switch for the motor 8 of pump 7. The shaft 83 is connected to a liquid displacement unit 117 which is combined with similar liquid displacement units 117<SP>1</SP> to operate the switch of motor 8 and 117<SP>11</SP> and 117<SP>111</SP> to operate the resetting mechanisms of registers 129 and 131 respectively. The motion transmission systems may also be adapted to drive auxiliary mechanisms for a cumulative register, a printing register and a predetermined stop device. Specifications 776,014, 778,171, 778,172, 778,173, 778,174, 893,891 and 908,977 are referred to.
