Abstract: A mechanism for converting a two-lever gasoline dispensing pump to a single lever system. The converted single lever unit includes a frame having an upper inverted U-shaped frame section and a pair of volume and cost registers are mounted in side-by-side relation within the upper frame section. A reset mechanism is operably connected to each register and the reset mechanisms are located at opposite sides of the frame. Each reset mechanism includes a shaft and the original operating handle located on the outside of the pump is carried by a second shaft which is off-set from the reset shaft and is connected to the reset shaft through a gear drive. When the hose nozzle is removed, the operating handle can be rotated to reset or clear the register and activate the fuel valve and pump. When dispensing has been completed, rotation of the handle to its original position will deactivate the fuel valve and pump, but the register will not be cleared until a subsequent resetting cycle is accomplished.
