Abstract
Abstract A fuel-supplying apparatus having a flowmeter and an indicator at a preferred location in a fuel-supplying conduit pipe suspended from above a fuel-supplying service area where vehicles are supplied fuel. The flowmeter and the indicator are provided at a location adjacent a delivery nozzle in the fuel-supplying conduit and readily observable by the operator supplying fuel with said nozzle in hand.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
A fuel-supplying apparatus comprising a structure having a ceiling or beam transversely extending above a fuel-supplying service area, a fuel reservoir, a fixed conduit having one open end in the fuel reservoir and extending through the structure, a movabLe fuel-supplying conduit having one end connected to the other open end of the fixed conduit and a forward end provided with a delivery nozzle, said movable fuel-supplying conduit being suspended from the ceiling or beam and adapted to be raised upwardly or lowered downwardly, a flowmeter located in a passage way of the movable fuel-supplying conduit at a convenient location spaced from the delivery nozzle by a predetermined distance so as to measure the quantity of fuel discharged through said passage way from the nozzle, and an indicator integrally provided with the flowmeter on the movable fuel-supplying conduit and directly displaying the measured amount of the flowmeter, wherein said flowmeter and said indicator are conveniently located in the movable fuel-supplying conduit between said nozzle and the head level of an operator operating the apparatus so that the indicator can be readily observable by the operator who is supplying fuel with the nozzle in hand and the flowmeter and the indicator do not obstruct the raising of the movable fuelsupplying conduit, said movable fuel-supplying conduit consists of a flexible material.
Claim 2
Dependent Claim
218 words
A fuel-supplying apparatus comprising a structure having a ceiling or beam transversely extending above a fuel-supplying service area, a fuel reservoir, a fixed conduit having one open end in the fuel reservoir and extending through the structure, a movabLe fuel-supplying conduit having one end connected to the other open end of the fixed conduit and a forward end provided with a delivery nozzle, said movable fuel-supplying conduit being suspended from the ceiling or beam and adapted to be raised upwardly or lowered downwardly, a flowmeter located in a passage way of the movable fuel-supplying conduit at a convenient location spaced from the delivery nozzle by a predetermined distance so as to measure the quantity of fuel discharged through said passage way from the nozzle, and an indicator integrally provided with the flowmeter on the movable fuel-supplying conduit and directly displaying the measured amount of the flowmeter, wherein said flowmeter and said indicator are conveniently located in the movable fuel-supplying conduit between said nozzle and the head level of an operator operating the apparatus so that the indicator can be readily observable by the operator who is supplying fuel with the nozzle in hand and the flowmeter and the indicator do not obstruct the raising of the movable fuelsupplying conduit, said movable fuel-supplying conduit consists of a flexible material.
Claim 3
Dependent Claim
107 words
The fuel-supplying apparatus of claim 1 which further comprises a wire leading from the flowmeter and extending along the movable fuel-supplying conduit, a second electric indicator fixed on a part of the structure for making indication by electric signals of the flow quantity of fuel delivered, and means for actuating the second indicator by signals transmitted through the wire, and wherein said flowmeter includes means for mechanically operating the first indicator integrally provided therewith responsive to the flow of fuel and means for generating the electric signals in accordance with flow quantity of the fuel and sending to the wire so as to operate the second indicator.
Claim 4
Dependent Claim
43 words
The fuel-supplying apparatus of claim 2 which further comprises a zero-resetting means consisting of a mechanism for mechanically returning pointer needles of the first indicator to a zero position and means for electrically generating zero-resetting signals simultaneously with an operation of the mechanism.
Claim 5
Dependent Claim
39 words
The fuel-supplying apparatus of claim 2 wherein electric currents of the electric signals flowing through the wire are small currents such that spark energy produced from the electric currents is smaller than the minimum firing energy of fuel atmosphere.
Claim 6
Dependent Claim
54 words
The fuel-supplying apparatus of claim 2, wherein said means for actuating the second electric indicator consists of means for electromagnetically sending and receiving only the electric signals being electrically insulated from the wire leading from the flowmeter, and a second wire sending signals received by the sending and receiving means to the electric indicator.
Claim 7
Dependent Claim
109 words
The fuel-suplying apparatus of claim 2, wherein said electric signals generated by the flowmeter and sent to the wires are electric pulse signals, and said means for operating the electric indicator consists of a high frequency oscillator means for oscillating carrier waves to be modulated by the electric pulse signals sent through the wires from the flowmeter, an insulating coil including a transmitting coil and a receiving coil electric-currently insulated from each other and electromagnetically coupled with each other, said insulating coil transmitting and receiving the signals from the oscillator means, and means for taking out pulse signals again from signals of the receiving coil of the insulating coil.
Claim 8
Dependent Claim
37 words
The fuel-supplying apparatus of claim 1, wherein said movable fuel-supplying conduit between said nozzle and said flowmeter and indicator absorbs shocks inflicted on said nozzle so as not to transmit the shocks to the flowmeter and indicator.
