Abstract
A high-security fill cap is adapted for releasable attachment to the open end of a fill pipe, connected to an underground fuel storage tank or the like. The fill cap comprises an annular cap, a plurality of latches pivotally mounted on the cap for movement between latched positions engaging the pipe and unlatched positions disengaging the pipe, an actuating mechanism, including a handle, for moving the latches between their latched and unlatched positions in response to reciprocal movement of the handle, and a key lock secured centrally within the handle to selectively rotate a cam plate thereof between its locked and unlocked positions beneath the cap.
Claims16
A high-security fill cap adapted for releasable attachment to a fill pipe of a storage tank comprising
- an annular cap adapted for sealing engagement with an open end of said pipe,
- latching means movably mounted on said cap for movement between a latched position engaging said pipe and an unlatched position disengaging said pipe,
- actuating means for moving said latching means between its latched and unlatched positions in response to movement of said actuating means between lowered and raised positions, respectively, and
- locking means, including a locking lug, for selectively moving said locking lug between a locked position retaining said actuating means in its lowered position and a released position permitting movement of said actuating means to its raised position.
In a high-security cap having an annular cap, a pair of diametrically opposed latches pivotally mounted on a periphery of said cap, a centrally disposed handle movable between lowered and raised positions, and a link pivotally interconnected between said cap and each of said latches, the improvement comprising
- a pair of rails formed integrally on said cap to extend radially outwardly from said handle to each of said latches to fully cover the pivot connections between said links and each of said handle and said latches.
