ABSTRACT:
A plate adapted to be mounted over an opening in the casing of a gasoline sales pump supports a frame which in turn rotatably and axially slidably supports a plurality of totalizer shafts and dial wheels, and a drive shaft with plural gears each associated with one of the totalizers. Each totalizer shaft has a gear engagable with a gear on the drive shaft by axial motion of the totalizer shaft. A drive gear on the drive shaft is permanently connected to the resettable register of the pump. Springs bias the totalizer shafts out of engagement with the drive shaft gears. Actuating levers pivoted on the plate engage the totalizer shafts in opposition to the springs. A selector bar slidable through the plate opposite each level has an angled end that cams the lever to totalizer engaging position. Springs bias the selector bars, and plural locks having key actuated cylinders move the selector bars against their springs. Two detents or slide bars supported on opposite sides of the selector bars have cam openings that coact with the opposite ends of pins projecting from the selector bars to prevent depression of a second lock cylinder and selector when another is already depressed, and to release the first actuated detent by linial movement of the other detent. Springs bias the detents oppositely. An electric switch is located to be closed when one of the detents is displaced. A lever adapted to be connected to the reset shaft of the sales register of the gasoline pump is positioned to move the other detent. The switch is adapted to be connected in series with the delivery control circuit of the pump.
