Abstract
A machine for automatically applying lane dressing travels up and down the lane to apply dressing according to a certain predetermined and preselected pattern. A single dispensing head travels back and forth across the lane as the machine moves linearly along the lane so that dressing is transferred to a buffer brush that engages the lane surface and applies the dressing thereto. The oil pattern is determined by actuation and deactuation of the dispensing head as it traverses the lane, such control of the head being provided by a special pattern control device in the nature of a cylindrical pattern tube that extends alongside the path of travel of the dispensing head. A sensor on the dispensing head detects pattern structure on the control device to responsively actuate and deactuate the head. In a preferred form, such structure takes the form of a series of metallic strips extending parallel to the path of travel of the dispensing head and spaced circumferentially around the periphery of the pattern tube. The sensor on the dispensing head is in the form of a proximity sensor that responds to the presence and absence of such metallic strips. At the end of each traverse of the dispe…
