Abstract: 465,694. Coin - freed apparatus. KOOPERATIVA FORBUNDET FORENING U.P.A. June 18, 1936, No. 16962. Convention date, June 18, 1935. [Class 27] Coin-action, mechanical-connection, with delivery proportionate to value, of coin.- Mechanism for summating the values of a number of different coins, and controlling, for example, the operation of an associated delivery apparatus, comprises a series of interconnected coupling members, one for each coin, each of which members is displaced relatively to the preceding when the appertaining coin is inserted by an amount proportionate to the value of such coin, the displacement of the end member being consequently proportional to the total value of the coins inserted. The mechanism shown is constructed to receive coins of 5, 10, 15, and 50 cents, and 1 dollar, which are insertable into separate pockets 92. Working in a side aperture in each pocket is a piston 96 secured to a common frame 95 which is reciprocated once at each operation of the mechanism by a motor driven cam 99 and return springs 97. The movement of the pistons 96 is transmitted through the coins where present, to respective impulse members 1-5 carried by sliding arms 16-20 secured to the outer ends of coaxial slidable sleeves 21-24 and a shaft 25. Rotatablv mounted on the inner ends of these sleeves and shaft within a fixed casing 38 are series of toothed discs 40-44 each of which moves axially with its sleeve or shaft. The toothed disc 40 moreover slides on a fixed pin 64, the disc 41 on a pin 65 secured to an outer disc 69, the disc 42 on a pin 66 secured to a second outer disc 70, the discs 43 and 44 being similarly connected with outer discs 71 and 72 ; all the outer discs 69-72 and a further similar disc 73 being journalled for rotation one within the other and in an end bearing 57. The teeth of the discs 40-44 are alternatively engaged by a pair of internal teeth on each of the outer discs 69-73, the engagement being maintained by a spring 32, acting on a shaft 30 connected through gearing 28 and 29 with the shaft of the end disc 73, and against the fixed pin 64. The pitch of the teeth on each of the discs 40-44 corresponds to the relevant coin value, e.g. the disc 40, Fig. 4, for 5 cent pieces having 20 teeth, the disc 43 for 50 cent pieces having 2 teeth. When a 5 cent piece is inserted into the mechanism, the reciprocation of the disc 40 under the action of its impulse member 5 releases the outer disc 69 for rotation under the action of the spring 32 by <1>/20 of a revolution. If other coins are also inserted, the corresponding discs 41-44 are also reciprocated, and the corresponding outer discs 70-73 released for rotation relatively to their discs 41-44 and the preceding outer disc by an amount determined by the pitch of the teeth on the respective discs 41-44 and the corresponding coin value ; the rotation of the end outer disc 73 being the sum of the relative rotations of the outer discs 69-73, and proportional to the total value of the coins inserted, this rotation being communicated to the shaft 30 controlling the associated delivery apparatus. Backward rotation of the shaft 30 to its initial position after the delivery operation rewinds the spring 32 ; this movement being not communicated to the summating mechanism owing to the interposition of a pawl and ratchet 35, 36. The impulse members 1-5 may alternatively be operated by electromagnets energized by the insertion of the coins.
