Abstract: A bowling pin for use with an automatic scorer includes a wood core and an ionomer cladding having an outer surface which surrounds the standing portion of the pin. The pin includes a first fluorescent coating on the outer surface in a preselected area, preferably in the neck portion of the pin. This first fluorescent coating emits a relatively high level of visible light when subjected to ultraviolet light. A second fluorescent coating, which is colorless under ambient light, covers the standing portion of the pin, including the first fluorescent coating and emits a relatively low level of visible light, i.e., the moonglow effect. The second coating also allows the relatively high-intensity visible light which is emitted from the first fluorescent coating to pass therethrough for detection by an automatic scorer.

Abstract: An apparatus applies dressing fluid to a bowling lane surface in a desired lane dressing pattern laterally across a plurality of zones on the bowling lane and longitudinally along a predetermined length of each of the zones. Each zone may be the width or a selected fractional width of one board across the bowling lane so that different discrete amounts of lane dressing can be applied to each board along a predetermined length. The apparatus includes a plurality of metering devices which supply lane dressing to corresponding lane dressing dispersion units which in turn supply lane dressing directly to an applicator. The applicator applies the lane dressing to the bowling lane according to the desired lane dressing pattern. A method is provided to supply discrete amounts of bowling lane dressing at desired incremental locations laterally across and longitudinally along a bowling lane.

Abstract: A bowling alley return mechanism includes a horizontal ball return disposed between two adjacent lanes, a pair of side walls which define a chamber and a ball door or opening in one of the side walls. A generally crescent-shaped concave pivotally mounted cradle is disposed within the chamber and adjacent to the opening for receiving a bowling ball thereon. The mechanism also includes an optical sensor which is responsive to a portion of the bowling ball when the bowling ball is on the cradle. A bell crank and linkage rotates the cradle in response to a signal from the sensor. The mechanism also includes an exit door and a releasable locking assembly of the pin and groove type which prevents any flying pins from passing through the exit door. The locking assembly is responsive to an upper portion of a bowling ball when the ball is moved by the cradle to unlock the exit door and allow the ball to pass therethrough and into the horizontal ball return for propulsion to the opposite end of the alley.
