Abstract
A pin table for a bowling pin spotting/respotting device is fabricated from stamped sheet metal and has lips around the periphery of the sheet metal pin table, as well as around each of a plurality of pin openings through the pin table. The sheet metal pin table is generally planar in configuration and has a plurality of pin openings. The lips extend upwardly around the periphery of the pin table and around the periphery of each of the openings. The lips provide sufficient rigidity to the pin table to enable its manufacture from stamped sheet metal rather than a more expensive aluminum casting. A respot actuating assembly for use with the aforementioned table includes a respot cam link mechanism, a pair of crank arms and an adjustable stop mechanism for limiting rotation of the crank arms. Linkage connects the crank arms to the respot cam link mechanism and to multiple pairs of gripper rods for gripping and releasing a plurality of bowling pins.
