Abstract
Abstract Means for inhibiting the escape of liquid from a liquid electrolyte battery having at least one fluid vent, wherein the battery is subject to frequent partial rotation about a horizontal axis, such as in the mounting of a power-assisted manually operated golf-bag carrying tricycle cart. The apparatus comprises a manifold and a hollow tube defining a coil substantially in a plane perpendicular to the axis of contemplated battery rotation, the coil having an outlet suspended normally directly downwardly.

Means for inhibiting the escape of liquid from a liquid electrolyte battery having at least one fluid vent, wherein said battery is subject to frequent partial rotation about a horizontal axis, said escape inhibiting means comprising: a manifold on a normally top side of said battery sealably enclosing said fluid vent and having an outlet which is normally downwardly disposed and which protrudes from the top side of said battery over a vertical side, the vertical side being disposed perpendicular to said axis of rotation of said battery; a hollow tube defining a coil which is substantially wholly in a plane perpendicular to said axis of battery rotation, the coil having an inlet coupled to said manifold outlet and further having a coil outlet suspended normally directly downwardly from the center of said coil and below the coil inlet, and wherein the coil is mounted external of the battery on one side thereof, whereby liquid discharged from said manifold is inhibited from draining from said battery as said battery is tilted.
