  • Range extending attachment for use in a price display mechanism
    Patent number: 3962568
    Abstract: This disclosure is directed to an attachment for a limited range gasoline pump. Many gasoline pumps are limited in price range to $9.99. The apparatus comprises an attachment wherein the number one is located on the face of the pump to extend its range to $19.99, and a flag bearing a dollar sign is placed over the number one. The flag remains in position if the sale is $9.99 or less. If that value is exceeded, the flag is moved to the left to expose the one, keeping the dollar sign correctly located. Movement is controlled by a cam attached to the rotating number wheel which displays the dollar value. This wheel is mounted on a cross shaft. The attachment cooperates with the cross shaft to respond to movement thereof to provide a reset motion when the gasoline pump is reset to zero.
