Claim 1
Independent Claim
199 words
A vehicle adapted for racing having a body, a pair of front wheels and a pair of driving rear wheels provided with rubber tires having generally cylindrical road engaging surfaces characterized by the improved construction comprising a tank having a lower and an upper portion mounted in a fixed position on the vehicle adjacent to the rear driving rear wheels thereof adapted to contain a liquid cleaning agent in the lower portion thereof and a substantial quantity of gas in the upper portion thereof, said tank having an opening in the upper portion thereof for partially filling the tank with said liquid cleaning agent and means operatively associated with the tank for injecting gas therein to pressurize the tank with respect to atmospheric pressure including a removable cap for sealing said opening, and conduit means communicating with the lower portion of the tank and extending to a region adjacent to the forward side of each of the driving wheels, said conduit means having a discharge nozzle confronting the generally cylindrical road engaging surface of each of the rubber tires, and said conduit means having a manually actuable normally closed valve for discharging the liquid cleaning agent from the tank.
