Abstract: 744,194. Counting-apparatus. VEEDERROOT, Inc. July 27, 1953 [Aug. 8, 1952], No- 20751/53. Class 106 (1). [Also in Group XVIII] Apparatus for 'dispensing selected ratio mixtures of two different liquids comprises separate flow lines with a common discharge nozzle for the liquids each line having a pump, a manually adjustable control valve and a flow meter having an output shaft, a total cost indicator, a firstdifferential gear having a pair of input shafts driven by the output shafts of the meters and an output shaft driving the total cost indicator, a total quantity indicator and a second differential gear having a pair of input shafts driven by the output shafts of the meters and an output shaft driving the total quantity indicator whereby the total cost and the total quantity of the mixed liquids dispensed are indicated. Liquid fuel of different octanes is contained in separate tanks 10, 10<SP>1</SP> and is driven by pumps 12, 12<SP>1</SP> through meters 15, 15<SP>1</SP> and valves 17, 171 to pipes 19, 191 connected to two coaxial delivery pipes 22, 22<SP>1</SP> past two poppet one-way valves to a mixing chamber 25 of a nozzle 23. A selector dial 33 carrying the numbers of octane ratings is mounted on a shaft together with a supporting plate 35. The plate 35 has a series of individually manually adjustable price dials secured thereto by pins 36 and the dials have notches engaged by spring detents on the plate 35 to retain the plates in position until the price is changed. A gear 53 is also mounted on the shaft and meshes with a gear 54 mounted on the lower part of a bracket 41 which acts as a bearing for the dial and plate and as a support for a spring detent which holds the plate in position. On setting the dial the octane number appears in a window 57 and the price per gallon appears in window 59 the gear 53 drives the gear 54 which is in mesh with gears 56, 561 operating valves 17, 17<SP>1</SP>. Two variators 60, 60<SP>1</SP> are provided having drive shafts 61, 61<SP>1</SP>   connected through universal joints with meter shafts 62, 62<SP>1</SP>. Two sets of price indicator wheels 64, 64<SP>1</SP> indicate the setting of the variators. A cost shaft 66, 66<SP>1</SP> is connected to each variator and drives a gallonage shaft 67, 67<SP>1</SP> through gears 70, 701 and 69, 69<SP>1</SP>. The gallonage shaft may be in direct communication with the meter shaft 61, 61<SP>1</SP>. The shaft 66, 66<SP>1</SP> is driven by differential mechanism within the variators to produce a rotation proportional to the setting of the indicator wheels 64, 64<SP>1</SP>. The shaft 66 66<SP>1</SP> is connected with the money totalizer 71,71<SP>1</SP> through shaft 73, 73<SP>1</SP>, gear 74, 74<SP>1</SP> and gear 72, 72<SP>1</SP>. Similarly the gallonage totalizers 75, 75<SP>1</SP> are driven by the shafts 67, 67<SP>1</SP>. The total cost is determined by a differential 80 having bevelled gears, a cage 82 with a gear 83, the differential being driven by shafts 84, 841 having gears 85, 85<SP>1</SP> in mesh with gears 72, 721 on shafts 66, 66<SP>1</SP>. The gear 83 drives a pinion 86 on the shaft 87 a pinion on which drives a pinion on a cost shaft connected to a register 88 having wheels 92 visible through a window. Similarly the total gallonage is indicated through a differential 94 driven by shafts 99, 99<SP>1</SP> from shafts 67, 67<SP>1</SP>. A bevelled gear 97 drives a gear 101 on a shaft 105 connected with gallonage indicator wheels 106 viewed through a window.
