Gasoline dispensing nozzle
First Claim
1. 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.

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.
