Pit Cushion Or Actuator Therefor Patents (Class 473/93)
-
Patent number: 7115040Abstract: A pit cushion assembly of an automatic pinsetter is fitted with a pit cushion follower assembly that includes a cam and roller assembly that allows a pit cushion of a pin setting mechanism to move toward and away from a support arm on which the pit cushion is movably mounted without restricting a range of motion of the pit cushion away from the support arm. The cam is operative, upon movement of the pit cushion toward the support arm from an initial position thereof, to ride along the roller while driving the support arm to move. The cam is also operative to permit return movement of the pit cushion to the operative position thereof without restricting the range of pit cushion motion. The cam and roller-based follower assembly allows the pinsetter to operate more efficiently with less moving parts and with less maintenance requirements than with a traditional link-based follower assembly.Type: GrantFiled: January 7, 2005Date of Patent: October 3, 2006Assignee: Pinsetter Parts Plus, LLCInventors: Scott J.

Patent number: 7044862Abstract: The present invention is directed to apparatus for use with a bowling pin setting apparatus having a shaker board, pit rug and a carpet cover having a Velcro hook connecting material secured to the bottom side thereof. This apparatus includes a sheet of plastic material sized to cover the pit rug. A Velcro hook connecting material is secured on the bottom side of the sheet and a Velcro loop connecting material is secured on the top side of the sheet. When the sheet of plastic material is positioned on the pit rug, the hook material secured to the sheet releasably secures the sheet to the pit rug and when the carpet cover is positioned on the sheet the hook material of the carpet cover releasably secures the carpet cover to the loop material secured to the sheet.Type: GrantFiled: October 20, 2004Date of Patent: May 16, 2006Inventor: William J. Scripps

Patent number: 6537157Abstract: A unique pit board is designed for bowling alleys of the type having a pit conveyor assembly with a shaker mechanism to convey downed pins to an associated pinsetter, and comprises top and bottom shell members constructed from a synthetic resin material. The top shell member has a formed upper surface which is inclined downwardly toward a marginal portion to convey downed pins to an adjacent pinsetter. The bottom shell member has formed reinforcing ribs to rigidify the same. The top and bottom shell members are interconnected in an overlying relationship to provide a very rigid, lightweight construction. A mounting member connects the pit board directly to the shaker mechanism without any intermediate frame.Type: GrantFiled: October 24, 2001Date of Patent: March 25, 2003Assignee: Brunswick Bowling & Billiards CorporationInventors: Edward J.

Patent number: 5437576Abstract: A combination bowling pinspotter and pinspotter control chassis system is disclosed which provides a bowling pinspotter having circuitry for permitting the spotting of bowling pins and an all solid state pinspotter control chassis coupled to the pinspotter for controlling the operation of the pinspotter. The all solid state pinspotter controller provides circuitry for executing a short strike cycles. In addition, the pinspotter controller secures power to a back end motor of the pinspotter in order to conserve the energy consumed by the back end motor. The pinspotter controller provides circuitry coupled to a remote control console for permitting the pinspotter to complete a current cycle prior to executing a shut down command for the pinspotter from the remote control console. In addition, the all solid state pinspotter controller retains status and position data for the pinspotter during power interrupts.Type: GrantFiled: November 8, 1993Date of Patent: August 1, 1995Assignee: Creative Technology, Inc.Inventors: William J. Tuten, Kennith D. Crosby

Patent number: 5330412Abstract: A bowling alley pit assembly for transferring bowling pins and balls to a pin elevator and ball return includes a base member having a forward and rear portion and a pair of laterally-spaced walls. The base member is disposed in a pit area of the bowling alley with the forward portion adjacent to the pin deck and the rear portion adjacent a pin elevating mechanism. A pair of rollers are disposed between the spaced walls and a motor is operatively connected to one of the rollers. A pit-wide endless belt passes around the rollers for moving fallen pins rearwardly away from the pin deck. The pit assembly also includes a one-piece or unitary, generally hollow, plastic bounce board disposed between the upper and lower portions of the endless belt and between the pair of rollers. The bounce board is transverse to the alley and defines two side-by-side, relatively flat portions which slope downwardly to form a shallow trough with a recessed area at one end thereof.Type: GrantFiled: July 13, 1993Date of Patent: July 19, 1994Assignee: AMF Bowling, Inc.Inventor: Michael W.
