Abstract
Abstract An automatic liquid dispensing nozzle wherein a lever, used to activate a control valve and regulate the rate of flow therethrough, is engaged by a holding means against the control valve, being released therefrom by automatic means upon the liquid being dispensed reaching a predetermined level, and subsequently being engaged by manual operation against a restraining member which permits the filling operation to be completed at a predetermined low rate of flow.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
241 words
In the automatic shutoff liquid dispensing nozzle of the type having a main body with a liquid conduit therein and a selfclosing valve for controlling the rate of liquid flow through said conduit, a hand operated lever movable about a fulcrum in a direction for opening said valve, means for holding said lever against said valve in open position during the automatic filling operation, automatic means for operatively releasing said lever from said valve to render the same inoperative, the improvement comprising means for engaging said lever for limiting the movement thereof to provide for partial opening of said valve for a low rate of liquid flow therethrough, said last named means including a lever guard extending about and in the plane of said lever, said lever guard having an opening in one extremity through which a free end of said lever extends, said lever guard on either side of said opening providing side legs, said means for engaging said hand operated lever comprising a Ushaped member fixedly embracing said one of the side legs of said lever guard, one leg of said U-shaped member extending into said opening in said lever guard and having a flat surface extending a substantial distance into said opening in the lever guard and providing a positive stop facing the free end of the lever in its said direction of movement for opening said valve, thereby to restrain said lever at said low flow position.
