Gas tank

Claim 1

A gas tank of the type adapted to be horizontally attached to the underside of a motor vehicle, and having, a bottom dishshaped, upwardly opening pan member, a top, dish-shaped, downwardly opening pan member, flange means along the peripheral edges of each said pan member, fastening means on said flange means securing said pan member together in open face-to-face relation, means on said top pan member for introducing gasoline into the tank, gasoline feed means on the tank for feeding the gasoline to the carburetor and combustion engine of the motor vehicle, said feed means being located near the tank''s forward end in the forward direction of travel of the vehicle, the improvement comprising: an insert comprising a shallow pan secured to the inside bottom wall of said bottom pan member, a short distance to the rear of said feed means, said shallow pan and said bottom pan member each being substantially rectangular and each having four substantially vertical sidewalls, three of said shallow pan sidewalls having substantially the same outside contour as the inside contour of said bottom pan member sidewalls, said three pan member sidewalls snugly embracing said three shallow pan sidewalls; a plurality of horizontally spaced, vertical separators provided within said insert extending in the direction of forward motor vehicle travel substantially across the entire length of said insert; the remaining one of said four shallow pan sidewalls extending transversely across the entire width of said bottom pan a slight distance from the remaining one of said bottom pan member sidewalls, and being inclined toward said feed means in a forward direction, whereby, as the gasoline is expended from the tank through said feed means below the height of said insert vertical sidewall, a quantity of gasoline will remain in the tank behind said remaining one of said shallow pan sidewalls even though gasoline is completely drained from the tank forward end so that, upon sufficient forward movement, during the braking action of the motor vehicle, of the gasoline remaining behind said remaining one of said shallow pan sidewalls spillover into the tank forward end will take place for feeding into said feed means, said separators serving to maintain a quantity of gasoline behind said sidewall during side-by-side movement of the motor vehicle, said separators being of a height substantially equal to the height of said remaining one of said shallow pan sidewalls, and each of said separators being perpendicular to said remaining one of said shallow pan sidewalls.
