Abstract: Multiple small-article receiving cassettes are provided for removably mounting on the upper surface of an inclined support. A drum housed within each cassette is rotated by connection with the drive shaft of a motor projecting through the support. The disk-like bottom of the rotatable interior drum of the cassette is undercut to form a circumferential series of radial and angularly spaced article receiving slots with the innermost end of the slots in overlying relation with respect to an outlet opening formed in the bottom stationary plate of the cassette. A second outlet opening, located in the upper surface of the support, is aligned with the opening in the bottom of the cassette. Upon proper rotation of the drum, articles placed within the cassette will travel along the receiving slots to their innermost end and then drop through the two outlet openings and into a dispensing chute. A single electrical control and single motor is used with numerous different cassettes for dispensing different drugs.

Abstract: A circuit and system is presented for controlling operation of a cell or hopper for dispensing controlled quantities of similarly shaped but different small articles. Copending patent application Ser. No. 533,255 filed on Dec. 16, 1974, by Hurst et al., discloses an article dispensing system providing a plurality of rotatable dispensing hoppers or cells each for dispensing during rotation a different article, specifically a drug tablet or capsule; the number to be dispensed being freely selectable. The present invention provides a modification of such system permitting a single cell to dispense several different items without fear of intermixing items. Pursuant thereto, a cell is filled with more articles than required and the system put into operation. The circuitry for each cell terminates dispensing of an article when the selected number of articles have been delivered to a dispensing chute.

Abstract: A small-article receiving hopper is mounted on the upper surface of an inclined support and is rotated by connection with the drive shaft of a motor projecting through the support. The disk-like bottom of the hopper is undercut to form a circumferential series of radial and angularly spaced article receiving slots with the innermost end of the slots in overlying relation with respect to an outlet opening formed in the support. A centralized electrical control means controls operation of a selected motor hopper of a plurality of motors, each associated with a different hopper for dispensing different drugs. The motor of the selected hopper is rotated until a desired number of pills is dispensed and is then stopped.
