Abstract
Abstract A nozzle having a valve housing and an elongated tube extending therefrom. The nozzle is provided with at least a slot near its open end. A latch is mounted within the nozzle which is movable between a first position, extending outwardly of the slot and a second position inwardly within the nozzle. The latch may be spring-biased or normally controlled to extend outwardly, so that once inserted within the vehicle, the gas tank will lockingly engage under its lip. The latch is provided with structure operable from the exterior of the nozzle which can selectively retract the latch and release the nozzle from the gas tank.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A nozzle for dispensing gas into a vehicle gas tank having an entrance pipe provided with a radially inwardly directed cap flange, comprising an elongated tube adapted to be axially inserted within the entrance pipe of said vehicle gas tank, a pair of toggle bars pivotally mounted about a common axis within said nozzle, said nozzle having a pair of diametrically opposed slots through which said toggle bars may move, a coil spring mounted about said axis, normally biasing said toggle bars in opposition to each other, extending outwardly through the respective slots, said toggle bars being movable between a first position extending radially outwardly through said slots into position to engage beneath said cap flange, and a second position retracted radially inwardly of said nozzle free of said cap flange, and means for selectively actuating said toggle bars into said first or second position.
Claim 2
Dependent Claim
145 words
A nozzle for dispensing gas into a vehicle gas tank having an entrance pipe provided with a radially inwardly directed cap flange, comprising an elongated tube adapted to be axially inserted within the entrance pipe of said vehicle gas tank, a pair of toggle bars pivotally mounted about a common axis within said nozzle, said nozzle having a pair of diametrically opposed slots through which said toggle bars may move, a coil spring mounted about said axis, normally biasing said toggle bars in opposition to each other, extending outwardly through the respective slots, said toggle bars being movable between a first position extending radially outwardly through said slots into position to engage beneath said cap flange, and a second position retracted radially inwardly of said nozzle free of said cap flange, and means for selectively actuating said toggle bars into said first or second position.
Claim 3
Dependent Claim
60 words
The nozzle as claimed in claim 1, including unlatching means mounted below said toggle bias and movable upwardly in engagement therewith for collapsing said toggle bars against the bias of said spring, a lever extending longitudinally through said nozzle, said lever being connected to said unlatching means at one end, and a selectively operable locking means at its upper end.
Claim 4
Dependent Claim
15 words
The nozzle as claimed in claim 2, wherein said locking means comprises a key-operated lock.
Claim 5
Dependent Claim
15 words
The nozzle as claimed in claim 2, wherein said locking means comprises a remote-controlled servomotor.
Claim 6
Dependent Claim
170 words
A nozzle for dispensing gas into a vehicle gas tank having an entrance pipe provided with a radially inwardly directed cap flange, comprising an elongated tube adapted to be axially inserted within the entrance pipe of said vehicle gas tank, a pair of opposed slots formed in the wall of said tube, a pair of ratchet bars reciprocable in opposite directions in a plane transverse to the longitudinal axis of the tube, a pinion engaging said ratchet bars, a rod fixed to said pinion extending longitudinally through said tube, a servo-motor mounted on the exterior of said nozzle having connecting means extending within said nozzle in connection with the upper end of said rod, said servo-motor being selectively actuable to rotate said rod to reciprocate said ratchet bars respectively through said slots, said ratchet bars being movable between a first position extending radially outwardly through said slots into position to engage beneath said cap flange, and a second position retracted radially inwardly of said nozzle free of said cap flange.
Claim 7
Dependent Claim
170 words
A nozzle for dispensing gas into a vehicle gas tank having an entrance pipe provided with a radially inwardly directed cap flange, comprising an elongated tube adapted to be axially inserted within the entrance pipe of said vehicle gas tank, a pair of opposed slots formed in the wall of said tube, a pair of ratchet bars reciprocable in opposite directions in a plane transverse to the longitudinal axis of the tube, a pinion engaging said ratchet bars, a rod fixed to said pinion extending longitudinally through said tube, a servo-motor mounted on the exterior of said nozzle having connecting means extending within said nozzle in connection with the upper end of said rod, said servo-motor being selectively actuable to rotate said rod to reciprocate said ratchet bars respectively through said slots, said ratchet bars being movable between a first position extending radially outwardly through said slots into position to engage beneath said cap flange, and a second position retracted radially inwardly of said nozzle free of said cap flange.
Claim 8
Dependent Claim
35 words
The nozzle according to claim 5, wherein said servo-motor is a push-pull solenoid and said connecting means comprises a ratchet arm connected to the solenoid and pinion fixed to the upper end of said rod.
Claim 9
Dependent Claim
23 words
The nozzle according to claims 5 or 6, including means for selectively biasing said servo-motor to effect outward movement of said ratchet bars.
Claim 10
Dependent Claim
20 words
The nozzle according to claim 7, wherein said biasing means includes sensor means for detecting the use of said nozzle.
