ing rags, deck brushes for washing rubber mats, ten azzo, etc. ; neutral soap and detergents, sweeping compound lor lloors beneatli seatnig, wood and metal polish, carbon tetrachloride, and gum remover. So that patrons themselves may help to keep the theatre clean, sand urns for cigaiette butts, gum wrappers, etc., should be judiciously distributed throughout tlie lobby, foyer, lounges and standee area. Cleaning implements should include a flexible rod, commonly called a "snake," for opening up clogged toilets, drainpipes, etc. The easiest to use are types in which the rod coils up inside a container with means of turning the rod into the pipe. When the, obstruction has been removed, the soiled rod is wound up into the container, causing no mess. in connection with cleaning compounds, care should be used to assure use of a compound which requires the least amount of time and will not injure the surface. For the partial or complete cleaning of carpeting and other fabrics from time to time (that is, dry shampooing, as distinguished from daily vacuum cleaning), a soapless lather is available, which may easily be applied with a rubber mop or similar implement ; drying requires but an hour or two. A powder is also obtainable for carpet and fabric cleaning ; this is sprinkled on small areas at a time and brushed in, then after a few hours, when the fabric is entirely dry, the residue can be removed with a brush-type vacuum attachment. Yet another product for shampooing carpet on the floor is a compound dissolved in a small amount of water and applied principally with a rotary machine and removed with a vacuum cleaner. Safety ladders are also to be considered among cleaning as well as equipment servicing accessories {see Ladders, Safety). Bigelow-Sanford Carpet Company, 140 Madison Avenue, New York City.

CLEANING MECHANISMS ECONOMICAL AND Safe cleaning of theatre carpeting, drapes, seating fabrics, etc., require regular and frequent application of vacuum cleaning equipment. Carpeting, for example, should be vacu um-cleaned daily. Vacuum cleaners may be used for other cleaning jobs around the theatre, such as blowing dust from out-of-the-way places, drying wet floors and carpeting, and so on, Theatres really require heavy-duty vacuum cleaning equipment. Ordinary domestic type cleaners are useful as auxiliary equipment, but they have neither the endurance nor the suction demanded by theatre cleaning. Of the heavy-duty equipment, two types may be regarded as specifically adapted to theatre work. One is the central system, with pipes leading to outlets so placed as to provide access at least to all public areas of the theatre. The other is a portable type, with power plant, suction mechanism and dirt disposal equipment on rollers, to which equipment the hose is attached. Portable models are available with motor and suction devices detachable, to be used as a hand unit. Theatres require a hose length on portable models of not less than 20 feet, and this may be provided in two sections, if desired, 10-foot lengths being connected by a brass coupling. Nozzles and brush attachments are available with both central and portable types for every kind of dry pick-up, and also for wet pickup. In portable units, the mechanism, with attached dust bag, should not weigh over 50 pounds so as to be conveniently carried on stairs and in seating area.

It serves a similar purpose in spotlight projection. The condenser is a single glass lens, unmounted, made in various shapes — moon shape, plan-o-convex, bi-convex and meniscus. The diameters of projection condensers range from 2% to 7J4 inches ; of spotlight condensers, from 5 to 8 inches. Focal lengths for theatre work runs from 6^ to 9J'2 inches.

CUPS, SANITARY FOR DRINKING INDIVIDUAL PAPER CUpS should be provided for patrons even though a bubbler fountain is installed. Some patrons much prefer cups for hygienic reasons. Also, if penny cup dispensers are used, they provide a source of extra revenue. Dixie Cup Company, Easton, Pa. Lily-TuHp Cup Corporation, 122 East 42nd Street, New York 17, N. Y. CURTAIN CONTROL SMOOTH AND silent opening and closing of curtains are effected, either from backstage or from the projection room, by automatic machines that operate at the touch of a button. The curtain may be stopped at any point along the stage, or its motion reversed as desired. Equipment consists of electric control mechanism for controlling travel of curtain. A motor and special gear reduction unit are employed to operate curtain at proper speed. Equipment can be furnished so that curtain control unit may "fly" with track and curtain. A special track is now available which operates curtain around a corner having 4^" radius. This permits installation of curtains in front of screens where there is not enough space in which to fold them. Automatic Devices Company, 1035 Linden Street, AUentown, Pa. J. R.

CURTAINS AND STAGE DRAPES CURTAINS USUALLY required for motion picture theatres in which stage performances are not regularly presented, are of the traveller type made up in such fabrics as velour. Asbestos fireproof proscenium-opening curtains are required in some States and all the larger cities in theatres having full stage facilities. Drapes are commonly indicated for the sides, and across the top of the proscenium opening; the extent to which they are needed is of course dependent upon the design of the proscenium area. Velours are indicated for such drapes also, but rayon-cotton mixtures and similar fabrics are also suitable. Companies capable of supplying these materials are also excellent sources of drapes for other parts of the theatre. Dazians, Inc., 142 West 44th Street, New York City.
