1388106 Random selections D RENOWDEN and J BENGHIAT [trading as HAMILTON] 22 Feb 1972 [26 Nov 1970] 56328/70 Heading G4D In apparatus for playing bingo or the like each player position has an extra lamp, these lamps being periodically energized in a continuous sequence until either the end of a time period or the completion of the game; if the last energized lamp coincides with the winner of the bingo game a larger prize is given. When a bingo game is started by energizing a pneumatic number ejector or "blower" motor, a relay X is energized. This de-energizes a flasher relay F but energizes a timer relay T and a motor DM which drives a rotary selector switch. The latter comprises a double sided printed contact stator (Figs. 2, 3, not shown), and a rotor carrying ten wiper contacts (Fig. 4, not shown). The stator has five concentric slip rings and two concentric sets of fifty contacts connected to fifty player positions. Eight of the wiper contacts WB-WE, RW2- RW5 connect four slip rings R2-R5 to four adjacent contacts LC of one set so that four lamps are lit at time in sequence. The other pair of wipers WA, RW1 connect the fifth ring R1 to one of the other set of contacts SC; the respective contact SC is only energized when the player position is in use, i.e. a fee has been paid. When the timer relay T releases contact T1 or the blower relay X releases contact X1 the motor DM stops at the next contact (by homing switch DMS), and the flasher relay is energized to flash the lamp then selected by wiper WE (the other three lamps can also flash if push buttons LPB are operated). If the selected player position is in use a sound relay S is energized and sounds a bell, &c. CH. Thus the lamps flash in a sequence until the end of the game when one or more of the lamps then alight continues to flash and if that player position is in use a bell sounds.
