Abstract: 798,879. Chance apparatus. ZEISEL, M., and KLEEBERGER, F. Sept. 20, 1956, No. 28739/56. Class 132(2) An electrically operated automatic roulette has a pointer which is driven for a short time by an electric motor after the insertion of a coin and contacts which are arranged in accordance with the number or colourfields and electrically connected to wagering switches selectively operated by the gambler. The pointer coming to rest or a contacting means revolving therewith closes by way of the contacts circuits for actuating counting or winning disbursing devices if the wagering switches have been correctly preset. Each number or colour field has a single contact and the wagering switches can be actuated to connect the single contacts individually and/ or in groups with devices which control a counting or disbursing of different winnings. and means are provided to justify the pointer. The motor M (Fig. 2) drives a shaft 43, by means of a worm gear 42, one revolution of which operates the whole game. The cycle is started by the insertion of a coin closing the switch SM thereby starting the motor, the power continuing via the switch nm which is closed by the cam NM on the shaft 43 . The motor also drives the pointer K until another cam NV closes a switch nv which operates a clutch V which takes the drive from the pointer K. The circuit through the pointer and wagering switches is a secondary circuit energized at T. A further cam NK keeps the switch nk open until the pointer stops, when current immediately. passes through the pointer and one of the numbered contacts. Wagering switches TA, TB, TC, TD are operated by the gambler. If one is set, say TA, only possible when the switch nr is closed by the cam NT thereby lighting the lamp LS. the lamp L9-15 illuminates and the switches a1, a2, a3 are closed connecting various numbered contacts with the switches n1, n2, n3 which are closed by cams N1, N2, N3 and which operate a disbursing device RZ, the relay R closing the switch r. The switches n1, n2, n3 may be closed several times according to the number of projections on the cams N1, N2, N3 so that different amounts are disbursed by the device Z. The switch ar is also opened to prevent current passing to the switches TB, TC, TD so that only one set of numbers can be pre-set. The cam NT is arranged to pass electricity to the wagering switches while the pointer is being driven but cuts it off and lights the lamp LNS as soon as the pointer revolves freely. A further cam NST closes a switch nst, lighting the lamp L2-8 and closing the switches e1, e2, e3, the numbers associated with which being considered wagered by the insertion of the coin. An additional wagering device is provided associated with the contacts #, 0, 1. Pointers I, 12 are revolved by the motor and current is passed through them. Wagering switches TH, TG, TO connect the contacts #, 0, 1, to the switch n2 but only if the pointers 11, 12 complete the circuit at the same time. If one is set, say TH, switches tH3, tH2 are opened thereby preventing the switches TG, TO from being operated. The wager will only become effective if the light LIH is illuminated, i.e. the pointers I1, 12 are in such a position that the circuit is completed. The pointers are arranged to revolve at different velocities so that lamps light up at irregular intervals. In a modification, a ball on a disc may be used instead of a pointer, the ball rolling in a groove on the disc after the disc stops. The pointer or disc or ball is prevented from coming to rest between contacts by means of magnets, or a pawl and ratchet. In the modification in Fig. 5, the wagering switch is a rotary one consisting of seven arms electrically insulated, through which one, two and four contacts are connected to the switches n1, n2, n3 respectively. The pointer K revolves as before, current being supplied through a switch nk operated by a cam NK. The rotary switch revolves on a shaft 53 and a cam NS corresponding to each contact closes the switch ns, so that if the wager is made after the pointer K has stopped revolving and the lamp LNS is alight, the switch S1 closes, and the switch S2 opens preventing any current from passing through the pointer K, so that no prize is won even if the correct wager is set. In the modification in Fig. 6 seven disbursing devices RZ1- RZ7, scaled in accordance with the probabilities of winning, can be individually connected to the contact arms KD1-KD7, K1D7 of rotary selectors W1-W7 with the aid of a change-over switch SD1-SD7, S1D7 having eight arms. During the time allowed by the cam NT, the contact arms KD1- KD6 can be adjusted with the aid of switches T1-T6 which can be actuated to connect the rotary magnets D1-D6 respectively of the selectors. The selectors W1- W3 have one contact path each whereas W4 has 4, W5 has 6, and W6 has 9. Each contact is wiped by a contact arm. There are 37 contacts in one ring all connected by multiple connection with the contacts which are arranged in accordance with the numbers and colours and which can be connected by means of the pointer K or the ball to the current source. The selector W7 has two paths, the contacts covered by the arm KD7 being connected to the contacts associated with the even numbers and the contacts covered by the arm K1D7 being connected to the contact associated with the odd numbers. To wager the evennumbered field the gambler must shift the change-over switch SD1-S1D7 to contact position 7 so that the disbursing device RZ7 is connected by way of SD7 to the contact arm KD7. After the pointer has run down freely a control cam ND7 connects the rotary magnet D7 of the selector W7 by way of S1D7-7-nd7 to the relay interrupter RU and the contact arm is stepped forward from one contact of the path to the other. If one of the contacts is supplied with current from K, the circuit of a relay P is closed, which opens a normally closed contact p whereby the magnet D7 is disconnected. The contact arm comes to rest at the contact connected to K so that the disbursing device R1Z7 is supplied with current and disburses a winning.
