  • Bowling lane oil application device and method
    Patent number: 6090203
    Abstract: An apparatus and method for applying a liquid dressing to a bowling lane has a chassis with wheels to guide the chassis along the longitudinal length of the lane. A spray nozzle for spraying the liquid dressing onto the bowing lane is mounted to reciprocation on the chassis and in a transverse direction parallel to the transverse width of the bowling lane. A metering valve meters liquid dressing to the spray nozzle as the spray nozzle moves in the transverse direction and at controlled velocity for applying the dressing in a selected profile across the transverse width of the lane.
