Abstract: 1,046,934. Bowling alleys. AMERICAN MACHINES & FOUNDRY CO. May 14, 1963 [May 18,1962], No. 19164/63. Heading A6D. The pinsetter deck of a bowling alley comprises a table 124 which is suspended from the fixed frame of the alley above the playing deck 110 thereof by means of a parallel linkage system connected to a rotatable shaft 143 in such a manner that rotation of the shaft 143 moves the table towards and away from the playing deck, the table remaining horizontal throughout. A solenoidcontrolled latch 175 (Fig. 7, not shown) is operative on one member in the system transmitting drive from the motor to the shaft 143, to control the descent of the table according to whether it is spotting or respotting.pins on the paying deck. The table comprises a triangular array of apertures 126. The pinspotting unit comprises cups C1-C10 mounted above apertures 126, and adapted in their rest positions to receive pins lying horizontally, the cups being supported on shafts 181- 184 journalled in a yoke 190 mounted on the upper side of table 124 so as to be movable horizontally relative thereto. Shafts 181-184 are linked by tie rod rod 206 to be rotatable in unison to bring cups C1-C10 to their upright, pin-depositing positions, and shaft 181 is rotated from the output shaft 152 of motor 150 via members 228 and 214. Immediately after the pins are deposited on the playing deck, the yoke 190 is arranged to move relative to the pin deck to move the cups clear of the standing pins, prior to the table's being raised to its dwell position. The Respotter Units comprise pairs of gripper arms 275, 276 located above and, adjacent each aperture 126, being mounted on and operated by a framework comprised of interconnected linkages 261-265. The linkage 261 is driven from the output shaft 152 of motor 150 via members 353, 366, 332, and in turn operates linkages 262-265 to close all the pairs of gripper arms, the arms being arranged to grip any off-spot spins within the limits imposed by the apertures 126. The outer ends of arms 275, 276 preferably each extend beyond their associated aperture when in their closed position and are biased into engagement with adjacent portions of the table by the weight of a lifted pin to prevent movement of the pin relative to the associated aperture whilst the table ascends and descends during the respotting cycle. Switches provided on the gripper arms are arranged in a control circuit for the motor 150 to condition the operation of the latter to initiate a fresh respotting cycle in the event of a strike being bowled with the first ball of the frame. Cams on the output shaft 152 operative to ensure the correct sequence of operation of the table, spotter and respotter mechanisms, by controlling movement of members 143, 228 and 353.
