Abstract
A gasoline dispensing unit and method according to which one end of a cord is attached to a dispensing hose to support the hose relative to a dispenser unit during non-use. The other end of the cord is attached to a drum having a tapered outer surface and a continuous spiral groove. When the hose is not in use, the cord is wound on the drum from the largest-diameter drum portion to the smallest-diameter portion. The cord thus unwinds from the drum from its smallest-diameter portion to the largest-diameter portion when the hose is pulled from the housing to provide a mechanical advantage and reduce the required pulling force.
