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.
Claims19
An apparatus for applying a liquid dressing to a bowling lane having a longitudinal length and a transverse width, comprising:
- a chassis;
- guide means connected to the chassis for guiding the chassis for movement along the bowling lane in a longitudinal direct parallel to the longitudinal length and at a longitudinal velocity;
- at least one spray nozzle for spraying the liquid dressing onto the bowling lane;
- reciprocation means connected between the chassis and the spray nozzle for moving the spray nozzle in a transverse direction parallel to the transverse width of the bowling lane and at a transverse velocity;
- metering means for metering liquid dressing to the spray nozzle as the spray nozzle moves in the transverse direction for applying a selected rate of the dressing in a selected pattern across the transverse width;
- and
- dressing profile means connected to at least one of the reciprocation and metering means, for varying at least one of the transverse velocity, the selected rate and the selected pattern, for applying the liquid dressing to the bowling lane in a selected profile which varies in thickness across the width of the lane so that the thickness is greater toward the center of the lane than at ends of the lane along the length.
A method for applying a liquid dressing to a bowling lane having a longitudinal length and a transverse width, comprising:
- supplying dressing under pressure to a spray nozzle to form an atomized spray;
- directing the atomized spray directly against the bowling lane;
- reciprocally moving the spray nozzle parallel to the transverse width and at a selected transverse velocity along the transverse width;
- longitudinally moving the spray nozzle parallel to the longitudinal length of the bowling lane;
- and
- selectively controlling at least one of the supply of dressing to the nozzle and transverse velocity to apply selected pattern of dressing to the bowling lane which varies in thickness across the width of the lane so that the thickness is greater toward the center of the lane than at ends of the lane alone the length.
