Abstract
Abstract An apparatus for dispensing a selected grade of motor fuel (each grade having a different octane rating) has an array of operating pushbuttons a selected one of which may be actuated (the selection being made according to the grade of fuel desired) to start the dispensing operation. Upon the actuation of a pushbutton, certain instrumentalities in the apparatus are energized or released to (among other things) select gearing in the apparatus appropriate to the grade selected, reset the counter or register to zero, set a control valve to a predetermined position, and start up the pump to cause the dispensing of fuel to begin. All of these functions are performed automatically, i.e., without any further human intervention, once the pushbutton has been actuated. Upon the termination of the actual dispensing, electrical instrumentalities are automatically activated to carry out certain resetting operations, prior to the next dispensing operation. The dispensing apparatus is particularly suitable for a self-service type of operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
In apparatus for the simultaneous delivery of two liquids in any selected one of a plurality of preestablished ratios, individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, a plurality of manually operable pushbuttons one for each of said preestablished ratios, and means operating automatically, in response to the operation of a selected one of said pushbuttons, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated.
Claim 2
Dependent Claim
104 words
In apparatus for the simultaneous delivery of two liquids in any selected one of a plurality of preestablished ratios, individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, a plurality of manually operable pushbuttons one for each of said preestablished ratios, and means operating automatically, in response to the operation of a selected one of said pushbuttons, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated.
Claim 3
Dependent Claim
41 words
Apparatus recited in claim 1, wherein said pushbuttons are resiliently urged toward their unoperated positions, said apparatus including also means acting in response to the operation of any one of said pushbuttons for mechanically locking the same in its operated position.
Claim 4
Dependent Claim
178 words
In apparatus for the simultaneous delivery of first and second liquids in any selected one of a plurality of preestablished ratios ranging from a zero ratio of the first to the second to an infinite ratio of the first to the second, individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, a plurality of manually operable pushbuttons one for each of said preestablished ratios, first means operating automatically, in response to the operation of a selected one of said pushbuttons, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated, and second means operating automatically, in response to the operation of said one selected pushbutton, for causing the presetting of said valves to one or the other of two predetermined positions depending upon which particular pushbutton has been operated, said second means having certain elements in common with said first means.
Claim 5
Dependent Claim
178 words
In apparatus for the simultaneous delivery of first and second liquids in any selected one of a plurality of preestablished ratios ranging from a zero ratio of the first to the second to an infinite ratio of the first to the second, individual means metering the deliveries of said liquids, valves individually controlling the deliveries of said liquids, adjustable means operated by said metering means and simultaneously controlling said valves to effect the delivery of said liquids in substantially a predetermined ratio, a plurality of manually operable pushbuttons one for each of said preestablished ratios, first means operating automatically, in response to the operation of a selected one of said pushbuttons, for adjusting said adjustable means to a position depending upon which particular pushbutton has been operated, and second means operating automatically, in response to the operation of said one selected pushbutton, for causing the presetting of said valves to one or the other of two predetermined positions depending upon which particular pushbutton has been operated, said second means having certain elements in common with said first means.
Claim 6
Dependent Claim
61 words
Apparatus set forth in claim 3, wherein the valves are preset to one of said predetermined positions for all of said plurality of preestablished ratios of liquids except an infinite ratio of the first liquid to the second liquid, and are preset to the other of said predetermined positions for an infinite ratio of the first liquid to the second liquid.
