Abstract
Abstract A fuel supplying apparatus comprises a single fuel feeding port including a pumping means, a motor for driving the pumping means, a flowmeter and an indicator; and a plurality of fuel supplying parts which are fed the fuel through the flowmeter from the fuel feeding part. The fuel supplying apparatus further comprises an interlocking device actuating to stop the motor for driving the pumping means, when one fuel supplying part is operated to start the fuel supplying while other fuel supplying part is supplying the fuel, thereby to interrupt the fuel supplying and prevent the fuel supplying to be performed simultaneously at two or more fuel supplying parts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
A fuel supplying apparatus comprising a fuel reservoir in which a fuel is stored, a pump for feeding the fuel from said reservoir, a motor for driving said pump, a power source for driving said motor, a flowmeter for measuring volume of the fuel fed by said pump, an indicator for indicating the measured volume of said flowmeter, a plurality of fuel supply parts including fuel supply hoses respectively having fuel supply nozzles at forward ends thereof, conduit pipes respectively leading the fuel fed through said flowmeter to said plurality of fuel supply parts, fuel supply part switches respectively provided in said fuel supply parts and switched over to act in cooperation with the starting of fuel supply of said fuel supply parts, and an interlocking circuit which is actuated in such way that it closes a power source circuit of said motor only when either one of said fuel supply part switches is switched over and opens said power source circuit when other switch is switched over said one switch being switched.
Claim 2
Dependent Claim
173 words
A fuel supplying apparatus comprising a fuel reservoir in which a fuel is stored, a pump for feeding the fuel from said reservoir, a motor for driving said pump, a power source for driving said motor, a flowmeter for measuring volume of the fuel fed by said pump, an indicator for indicating the measured volume of said flowmeter, a plurality of fuel supply parts including fuel supply hoses respectively having fuel supply nozzles at forward ends thereof, conduit pipes respectively leading the fuel fed through said flowmeter to said plurality of fuel supply parts, fuel supply part switches respectively provided in said fuel supply parts and switched over to act in cooperation with the starting of fuel supply of said fuel supply parts, and an interlocking circuit which is actuated in such way that it closes a power source circuit of said motor only when either one of said fuel supply part switches is switched over and opens said power source circuit when other switch is switched over said one switch being switched.
Claim 3
Dependent Claim
131 words
The fuel supplying apparatus as defined in claim 1, wherein said interlocking circuit comprises a power source switch opening or closing a power source circuit of said motor, exciting coils switching over said power source switch, a group of contacts opening or closing a power source circuit of said exciting coils, and exciting coils respectively connected to said fuel supply part switches and actuating each responsive contact out of said group of contacts, wherein said group of contacts are so constructed that said group of contacts switch over the power source circuit of the exciting coil for the power source switch so that the power source switch is opened when other fuel supply part switch is switched over in a state that one fuel supply part switch has already been switched.
Claim 4
Dependent Claim
121 words
The fuel supplying apparatus as defined in claim 1, which further comprises a casing having said pump, motor, flowmeter and indicator housed therein and having one of said fuel suppLy hoses provided thereon, said casing being fixed on the ground surface, a structure of ceiling or beam transversely extending over a fuel supply service area, and delivery units provided on said structure and having said other fuel supply hose movable upwards and downwards, wherein said conduit pipes consist of a first conduit pipe leading the fuel to said one fuel supply hose and a second conduit pipe branched from said first conduit pipe, said second conduit pipe extending along said structure and leading the fuel to said other fuel supply hose.
Claim 5
Dependent Claim
122 words
The fuel supplying apparatus as defined in claim 1, which further comprises a casing having said pump, motor, flowmeter and indicator housed therein and having one of said fuel supply hoses provided thereon, said casing being fixed on the ground surface, and a nozzle hanger post fixed on the ground surface at a spaced position from said casing in the fuel service area, wherein other one of said fuel supply hose being provided on said nozzle hanger post, said conduit pipes consist of a first conduit pipe leading the fuel to said one fuel supply hose and a second conduit pipe branched and extending from said first conduit pipe, said second conduit pipe leading the fuel to said other fuel supply hose.
Claim 6
Dependent Claim
74 words
The fuel supplying apparatus as defined in claim 1, which further comprises a ceiling or beam structure transversely extending over a fuel supply service area and delivery units provided respectively on said structure spaced apart and respectively provided with fuel supply hoses movable upwards and downwards, wherein said conduit pipes extends along said structure so as to lead the fuel fed passing through said flowmeter to the fuel supply hose of each delivery unit.
Claim 7
Dependent Claim
102 words
The fuel supplying apparatus as defined in claim 1, which further comprises a zero-resetting motor for resetting the indication of said indicator to zero position, a contact mechanism for closing a power source circuit of said zero-resetting motor by switching of one of said fuel supply part switch, a cam having a land and a recess and being rotated by rotation of said zero-resetting motor, a contact member displaced in contact with the land and recess of said cam, and a changeover switch inserted into said power source circuit of said zero-resetting motor and switched over by displacement of said contact member.
Claim 8
Dependent Claim
53 words
The fuel supplying apparatus as defined in claim 6, which further comprises a second power source switch inserted into said power source circuit of said motor for driving said pump, said second power source switch opening said power source circuit of said pump driving motor during operation of zero-resetting by said zero-resetting motor.
