498,145. Coin - controlled apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. July 20, 1937, No. 20023. [Class 27] Coin action, mechanical-connection and multiple-coin.-Relates to coin-controlled mechanism of the kind described in Specification 320,613, [Class 27], in which coins inserted in a bunch in a shoot 6, Fig. 1, are fed forward by a powerdriven rotary disc 4 to actuate a control element 14 in accordance with the value of the particular coin and, when coins amounting to a predetermined value have passed, the control element 14 effects or permits operation of the mechanism controlled. According to the invention, in order that the mechanism may be operated by polygonal threepenny bits as well as by pennies and halfpennies, two feelers are provided operating the control element 14, one being actuated by the pennies and halfpennies and the other by the threepenny bits. The disc 4 rotates in a casing 1 which is inclined at 60 degrees to the horizontal and is covered at its lower portion by a plate 5 carrying the shoot 6. The outer portion of the disc 4 is cut away to form an annular recessed path 15 divided into coin pockets 16 by pins 17 and arcuate ramps 18. The recess 15 is also provided on the same circle as the pins 17 and ramps 18 near the trailing ends of the pockets 16 with conical holes 20 flaring downwardly. The coins carried round in the pockets are discharged through an opening 45 formed by a recessed passage 21 in a plate 7. The recess 21 is formed with a passage 25, Fig. 3, just wide enough to take the threepenny bits, this passage being deeper at its upper than at its lower edge 48. A curved recess 22 allows the ramps 18 to pass. As the coins are carried round by the disc 4, the pennies and halfpennies actuate a feeler or finger 43 and rotate the toothed ratchet wheel 14 through two teeth for a penny and one tooth for a halfpenny. Threepenny bits are too small to actuate feeler 43, but are carried round and enter the passage 25. The nose 35 of a spring-pressed lever 10 enters a hole 20 and tilts the threepenny bit about the edge 48 so that it presses on a pin 31 on the lower of a pair of spring contact strips forming an electric switch 28. The circuit of a solenoid 32 is thereby closed and a rod 34 extending from its core 33 actuates an arm 41 bearing a pawl 42 which moves the wheel 14 through six teeth. Pennies and halfpennies are too large to enter the passage 25 and are discharged through the opening 45. The wheel 14 is provided with contacts 38 which successively engage momentarily with a brush 39 and close an electric circuit each time the wheel is moved through a predetermined distance, said circuit acting to effect or permit the actuation of the mechanism controlled.
