Abstract

A gasoline pump computer reset lock apparatus has a mounting bracket for being attached inside a gasoline pump housing. A bolt or plunger is moveably positioned in a plunger housing attached to the mounting bracket. The plunger is in a locked position when one of its ends is closed against a stop and is in an unlocked position when that one end is spaced back from the stop. A control apparatus is coupled to move the plunger to the locked or unlocked positions. One end of a link is attached to a rotatable crank member. The crank is coupled to a reset lever so that the link moves into the space between the plunger and the stop when the reset lever is rotated. The link is moveably attached to the mounting bracket so that when the plunger is in the locked position against the stop, the forward end of the link encounters the plunger and is prevented from moving into the space. When the plunger is in the unlocked position, the forward end of the link is able to move into the space between the end of the plunger and the stop.

Dependent claims

A fluid pump meter reset lock apparatus for use in a fluid pump assembly having a housing, a pump mounted in the housing, a meter apparatus mounted in the housing and interconnected to the pump for measuring the quantity of fluid pumped by the pump, an actuating lever apparatus for turning the pump on and off, and a reset lever apparatus having a reset lever and a reset axle rotatable in response to rotation of the reset lever for resetting the meter apparatus, the fluid pump meter reset lock apparatus comprising:

a mounting bracket for being mounted within the fluid pump assembly;
a plunger apparatus mounted to the mounting bracket having a plunger which is controllably moveable to a locked position and to an unlocked position;
a reciprocating link member having a leg portion movably attached to the mounting bracket and a base portion attached to one end of the leg portion, the other end of the leg portion positioned for encountering the plunger only when the plunger is in the locked position;
and
a rotatable crank member having a first end fixed to the reset axle whereby the crank member is rotated when the reset lever is rotated and further having a second end rotably attached to the base portion of the reciprocating link member whereby the plunger apparatus prevents the reset lever from being rotated to reset the pump meter when the plunger is in the locked position.
