Abstract
Abstract The filler neck gas cap of a vehicle owner is utilized as a prop for maintaining the lever of a gasoline pump dispensing nozzle in open position without the necessity of manual operation. In one embodiment, resilient material surrounds or is secured to diametrically opposite positions of the periphery of the gas cap. In another embodiment, resilient material is secured to axially opposite ends of the gas cap. The resilient material increases the coefficient of friction between the gas cap and nozzle lever and its guard when interposed therebetween while the lever is in nozzle open position.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
In a gasoline pump elongated dispensing valve nozzle having a laterally spaced longitudinally extending lever guard and having a variable position lever movable toward and away from the lever guard for dispensing and interrupting gasoline flow from the nozzle in combination with a vehicle gasoline tank filler neck gas cap having circular outer and inner end portions and having a diametric or axial dimension freely received between said lever and the lever guard when the lever is moved toward gasoline dispensing position, the improvement comprising: resilient material means having a surface providing a relatively high coefficient of sliding friction, when compared with metallic surfaces, including at least one strip extending transversely across the outer end portion of said gas cap; and, a cushion axially overlying the inward end portion of of said gas cap for maintaining said lever in gasoline dispensing position by increasing the coefficent of sliding friction between said gas cap and said lever and the lever guard.
