Abstract: An easily installed frictional bowling pin spot and a method of installing frictional pin spots on the pin deck of a bowling lane are disclosed. The preferred frictional pin spot is preferably a thin, circular polyurethane piece having a high coefficient of friction and packed with a pressure-sensitive adhesive. The pin spot increases the friction between a bowling pin and the pin deck thereby decreasing the likelihood of bowling pins hit by a ball or other pin sliding out of position instead of being knocked over.

Abstract: 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.
