ABSTRACT:
A fuel dispenser aid holds a trigger-like valve operating lever relative to a pistol grip-like handle portion of a valving device for dispensing gasoline or other fuels through a nozzle of the valving device without continuously manually holding the operating lever. The dispenser aid includes a mounting member formed of a material having a resilient, shape retaining character configured for mounting over the pistol grip-like handle portion of the valving device, a flexible strap secured at a first end thereof to the mounting member and extending freely therefrom so that it can be looped under the trigger-like valve operating lever and up to the mounting member and an arrangement for releasably and adjustably fastening the free portion of the strap to the mounting member. The mounting member is configured such that it can be held in one hand and clipped over the handle portion of the valving device in such a manner that the fingers of the one hand can both actuate the operating lever and loop the strap under and up to the mounting member to releasably fasten the strap thereon for securing the operating lever in the desired actuated dispensing position. The fuel dispenser aid offers the advantages of simplicity, relatively low cost and ease of use even for the handicapped operator.
