Abstract

303,844. Jackson, J. E. Evans-, (Accounting & Tabulating Machine Corporation). Oct, 10, 1927. Coupling machines for simultaneous operation; keyboard operators.-In a combined typewriting and punching machine for statistical cards, means is provided to establish or to interrupt an operative connection between the typewriter and the punch-selecting means, according to the position of the typewriter carriage. Actuation of typewriter keys 25, through a switch 21, normally closes a circuit through a solenoid 10 controlling one of a row of setting plungers 14 for gagging punches 16 when a die-plate 18 supporting the card is raised. The circuits are controlled by a stationary switch 24, common to all the solenoids, operated by a cambar 38 carried by the typewriter carriage. The bar may be provided with a number of faces carrying differently arranged projections and may be mounted to permit any face being brought into action. In operation, the bar 3S controls the switch 24, in accordance with the position of the typewriter carriage, to select the columns in which circuits for the solenoids become operative.
