Abstract: 498,178. Coin - freed amusement apparatus. BRYAN, W. E. Sept. 21, 1937, Nos. 25539 and 32835. [Class 27] The apparatus comprises a turntable 12, Fig. 1, divided by partitions 13 into compartments in which articles or prizes are displayed, the turntable being rotated after insertion of a coin, and an arm 16 having a depending sucker being oscillated over the table. To obtain a prize, a button 18 is depressed to stop the table while the sucker 17 descends to pick up a prize. If the player is successful the arm 16 is swung above a delivery opening 21 and the suction released to drop the prize. If the attempt is unsuccessful, the mechanism is repeatedly operated, without the necessity of inserting a further coin, until a prize is. delivered to the player. A coin inserted in a slot 14 tilts a counterbalanced lever 23, Fig. 2, carrying a mercury switch 26 to energize an electric motor which drives a shaft 27. The shaft 27 by a belt and pulley 29. 28 drives a large pulley 30 which contacts with the undersurface of the table 12 and rotates this. A connecting-rod 32 from the pulley 28 actuates a suction pump 33 connected by a pipe 35 to a balance cylinder 36 and thence by pipes 37, 38 and a filter 39 to the sucker 17. The shaft 31 of the pulley 30 through gearing 41, 42 drives a sleeve 43 rotatable on a shaft 44 and carrying a cam 45 and a ratchet wheel 46. The cam 45 acts on a roller 146 to swing a link 47 the lower end of which has a pin 49 engaging a notch in a bar 51 which is thereby oscillated and through a rod 55 rocks a vertical hollow rod 40 carrying the arm 16 and sucker 17. When the button 18 is depressed, a bar 70 is raised to free the lower end of a pivoted bar 66. This allows a spring 65 to rock a link 62 and engage a pin 64 thereon with the ratchet wheel 46. The link 62 is pivoted to a crosshead 60 on an assemblage 57 fixed to the shaft 44. The assemblage is thus rotated and a cam 58 thereof releases a bell-crank lever 71 which is pulled by a spring 73 to lift through links 75, 76 a bar 19. This bar 19, when raised, stops rotation of the table 12 by engaging one of a ring of unevenly spaced pins 20 projecting from the underside of the table. A rod 77 actuated by the link 76 raises the bar 51 and disconnects it from the link 47, so that oscillation of the arm 16 is stopped. A cam 81 on the shaft 44 rocks a bar 83 to raise a rod 85 and rock the arm 16 to cause the sucker 17 to descend among the prizes. If the sucker has picked up a prize, suction of the pump 33 causes a piston 86 to rise in the cylinder 36 and a collar 88 on the piston rod 87 to raise the free end of a bar 89, the other end of which is pivoted at 90 to a link 91. A second cam 59 of the assemblage 57 actuates a' link 93 to cause a rod 95 to rotate the pillar 40 and carry the arm 16 with attached prize over the delivery opening 21. Finally, a crank-pin 96 on the shaft 44 rocks the link 91 and causes the raised bar 89 to push aside the coin shoot 22 against the action of a spring 111. The coin drops to a cash-box and the lever 23 returns to break the motor circuit. A pin 99 on the bar 89 actuates a lever 100 to open a valve 103 in the cylinder and destroy the suction so that the prize can drop into the opening 21. At the end of the cycle, the cam 58 once more raises the lever 71 to restore the parts to their initial position. If a prize is not picked up by the sucker 18 the coin is not discharged and the cycle is repeated until a prize is picked up. In a modification, for prizes made of or enclosed in magnetic material, instead of a sucker, a pair of electromagnets are employed. If the player is successful, a circuit is completed through the cores of the electromagnets and the body of the prize. This energizes a winding to raise a solenoid core and actuate the bar 89 that co-operates with the coin shoot.
