Abstract
A bowling lane maintenance machine includes a shiftable head operable for discharging successive streams of lane dressing during successive passes along the length of an applicator assembly in order to apply lane dressing to a bowling lane according to a predetermined pattern. The preferred embodiment includes a positive displacement pump that delivers successive equal volumes of lane dressing so that the resulting streams are precisely controlled despite variations in the viscosity of the lane dressing.
