Abstract: A bowling lane having a substantially flat top surface including a foul line end and a pin deck end, the improvement comprising a method and assembly of a polymer sheet of polycarbonate having a thickness between about 0.63 and 2.50 mm, overlaid onto the top surface between the foul line end and pin deck rear end and having a leading edge portion and a trailing edge portion, a strip of double-sided adhesive tape beneath the leading edge portion for securing to the foul line end, and double-sided tape beneath the trailing edge portion for securing it at the pin deck end. Any other mechanical fastening system may also be used to adhere the sheet to the lane. The polymer sheet may be 100% polycarbonate, but may also include a first layer that optionally comprises a lubricious polymeric material such as Teflon® in combination with polycarbonate. The polymer sheet undersurface is free of adhesive.

Abstract: End and side panels, welded together to form a frusto-pyramid, are surmounted by a dished wheel-receiving platform, for supporting a truck etc wheel. The units are wide open underneath, for stacking. Hand holes in the end panels allow the units to be manhandled and stacked. A cross-brace under the platform strengthens the structure, and holds the stacked units apart.

Abstract: Time consuming analyzing of the dressing levels on bowling lanes is eliminated through the use of an apparatus that includes a path of travel (48) for a sample strip, a light source (50) on one side of the path (48) and a photosensitive sensor (46) on the other side of the path. A feed roller (60) is journaled adjacent the path and is driven by a stepper motor (58) in predetermined increments. An analog to digital converter (40) is connected to the sensor (36) for receiving analog signals therefrom and converting the same to digital signals. A random access memory (38) is connected to the converter (40) for receiving signals therefrom and for storing data represented by the signals. A central processing unit (34) is provided for operating the motor (58), the sensor (46) and the random access memory (38).

Abstract: An automatic pin setter includes a pinsetting deck structure movable toward and away from a pin supporting surface on a bowling lane for controlling setting of bowling pins on the lane supporting surface. A rake sweeps pins from the lanes. A rake up switch senses if the rake is in a raised position. A drive system is operatively coupled to the deck structure and rake and includes a cycle solenoid, the drive system for controlling an automatic pin setter cycle in response to energization of the solenoid. The pinsetter cycle controls movement of the deck structure and the rake to selectively remove or set pins on the lane. A pit cushion is positioned at a rear end of the lane and is linked to the rake to lower the rake from the raised position when a thrown ball strikes the pit cushion. A control comprises a ball sensor mounted on the lane before the pit cushion for sensing presence of a ball on the lane and developing an electrical trigger signal in response thereto.

Abstract: An improved guide finger 18 is provided to simplify the installation of guide fingers in pinsetters 10 used in bowling centers, having a mounting plate 24 and a guide plate 26, with the mounting plate having a plurality of mounting apertures 30 equipped with hexagonal sockets 32 for receiving the head of a machine bolt, the mounting aperture 30 is provided with a metal insert 38 and the guide finger 18 is preferably made of nylon.

Abstract: A molded rubber pin chute for mounting on the pin deck of an automatic bowling pinsetter. The pin chute comprises an upper conical section which is canted with respect to the pin deck, a cylindrical lower body portion which extends into a pin receiving aperture in the pin deck, and a flange around the cylindrical body. A plurality of bolt holes selectively positioned in the flange permit the chute to be secured in at least six different radial positions upon the pin deck and thereby enhance its performance in guiding the bowling pins into apertures in the pin deck for receiving the same.
