Abstract: 624,454. Dispensing liquids. S.A.T.A.M. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. March 7,1945, No. 5660. Convention date, Aug. 19, 1941 [Class 116] [Also in Group XIX] In a fluid measuring and dispensing device, the volume and cost of the liquid to be dispensed are set by a setting member before the dispensing commences, the setting member being connected to the volume and the cost pre-indicating devices through respective transmission means having relative transmission ratios depending upon the price per unit volume. The setting member may also set a control device which stops delivery when the predetermined quantity has been dispensed. In one form, Fig. 1, the setting member 8 operates the volume pre-indicating device 4, the cost pre-indicating device 5 through a variable-ratio transmission mechanism 7, and a device 6 for pre-determining the quantity to be delivered, this last device being driven at this time through the sun wheel 92, planet wheel 93 and cage 9 of a differential gear 9, the cage 9 being attached to a sleeve 94 connected to bevel wheels 96. The liquid meter is stationary and the other sun wheel 91 is thus held against movement. The setting member 8 is then locked and delivery started. The meter 1 drives a volume register 2 and, through the differential gear 9, the predetermining device 6. When the pre-set volume has been delivered, the device 6 closes a delivery valve 63 in known manner and also removes a shutter 54<SP>1</SP> to reveal numeral wheels 5<SP>1</SP> which are connected to the cost pre-indicating device 5 to repeat the setting thereof. In a modification, Fig. 2, the setting member 8 operates the volume pre-indicating device 4 directly and also, through worm gearing 81 and a differential 9, turns a shaft 98 which sets the delivery pre-determining device 6 and, through a variable - ratio transmission mechanism 7, the cost pre-indicating device 5. During delivery the meter 1 drives the volume register 2 and the shaft 98, but in the opposite direction to that imparted to the said shaft by the setting member. The shaft 98 turns the pre-determining device 6 back to zero and also operates a cost register 3 showing continuously the cost of the liquid actually delivered. The cost register is not driven by the setting device because of the action of a one-way drive means 33. In another form, Fig. 3, the setting member 8 is pushed to the left to engage a clutch 83 and lock the cost register 3 and is then turned to set a combined pre-indicating and delivery pre-determining device 6 through worm gearing 81 and a differential 9<SP>1</SP>. The setting device 8 also, through a variable-ratio transmission mechanism 7, sets the volume pre-indicating means 4. The setting device 8 is then returned to the right and so locks through linkage 84, 87, the cage 94 of a lower differential 9 so that the meter 1 in addition to driving the volume register 2 returns to zero the volume and cost pre-indicating devices and the delivery pre-determining device and also operates the price register 3. Specification 624,455 is referred to.
