in offering change to a patron and loss to the theatre through mistakes. The correct change is automatically determined upon manipulation of the proper keys, and is delivered into a metal cup, from which it is easily scooped. Not only greater accuracy, but greater speed in handling a line of patrons make changemakers a box office requisite. For attachment to change makers without such provisions, where admission taxes in pennies are added to the regular price, a penny chute is available. It is clamped to the side of the change-maker and holds about I. SO prnnics. Aero Metal Products Corporation, 4704 West Arthing ton, Chicago, 111. Brandt Automatic Cashier Company, Watertown, Wis.

CHANGEOVER AND CUEING DEVICES SWITCHING out one picture projector while switchirig in the other may be accompHshed in various ways according to the several types of devices available. The electrical type in general, performing its functions at the touch of a switch (either foot or hand), cuts off the light by a shutter arrangement while opening and closing the alternative circuits. There is also a mechanical device which merely cuts off the light at one projection port while opening the other. One mechanism that employs the port cutoff method of light interruption, is electrically operated and includes circuit switching means. One of the electrical changeovers cutting off the light at the aperture also provides for closing the speaker circuit, if this is desired. Yet another electrical device cuts off the light by a dissolving shutter mechanism in front of the projection lens. Several types of changeover time indicators are available, including reel-end alarm bells actuated by film tension, and also an indicator not attached to the projection mechanism which operates an alarm bell actuated by a clock mechanism that is preset according to a running time dial. {See Reel End Alarms.) Marking of cue signals on film is not approved of (Standard Release Prints have necessary cues when in proper condition) ; however, for those emergency occasions when cueing the print is deemed unavoidable, there is a simple marking device that presses small circles into the film with minimum damage.
