Locking brace for gasoline dispensing nozzles

Claim 1

An adjustable and portable prop means to be carried by a user for use with a fuel dispensing nozzle, said nozzle having a nozzle lever and lever guard, said nozzle lever being movable from a normally closed position to an open position for dispensing fuel, said portable prop means allowing the automatic control of the fuel-flow rate and the automatic and precise shut-off of the nozzle to thereby allow the unattended filling of a fuel tank and assure the automatic shut-off of said fuel flow without spillage when said fuel tank is full, said portable prop means being capable of insertion between said nozzle lever and said lever guard of said nozzle for exerting a continuous force against each of said nozzle lever and said lever guard in said open position, said portable prop means comprising opposing first and second portions of a non-sparking material, said first and second portions being connected by an adjusting means for varying the length of said portable prop means from a fully extended first position to a closed second position, and retaining said portable prop means at a desired length, opposing ends of said prop means being rounded to form a spherical segment to make said prop means responsive for precise shut-off of said fuel flow by automatic disengagement from said nozzle lever and said lever guard, whereby the fuel-flow rate of said nozzle may be controlled by biasing said opposing rounded ends of said portable prop means against each of said portable prop means being preadjusted to a desired length for effecting a desired flow rate, said flow rate being automatically shut-off by the response of said nozzle to the filling of the fuel tank.
