1130 THE MOVING PICTURE WORLD February 14, 1920 Preview with the DeVry ft CINCE a poor projector kills a good film, "pre^ view" your films with th^qualifj projector — the DeVry. The DeVry is mechanically superior. It is made with the accuracy of a fine watch. It stands up to hard work! All this, and more, is made evident by all its projections. Also — note these advantages: The De Vry lets you preview any film in your comfortable office — that keeps you out of the cold, empty theaterl It lets you preview u,'hile your theater is crowded — that saves your time! It costs nothing for an operator — that saves you money! In fact, a De Vry soon pays its first cost. To Film Exchanges a De Vry is of equal and inestimable value. The De Vry is housed in a handsome, leather-covered box. The box looks like a suitcase. Weighs 20 pounds. You carry it anywhere. It has its own motor. It projects a picture up to 12 feet square and up to 80 feet distant. You will like the De Vry! It is a real wonder. It does what we say. All we are asking is — the opportunity to show you! We are represented in 60 cities. Let us give you a free demonstration — in your own office, OT home. It's no trouble at all! It"s our business. There will be no obligation. (We have an interesting illustrated Booklet on the press.) So — wherever you live — we hope you will fill out and at once mail the coupon below. Why not do it — before you turn over this page?

He stated, also, that the popularity of the Typhoon system has been brought about through its low cost of installation and absolute reliability of operation. The following is a list of some of the more recent sales : Tivoli Theatre, Chattanooga, and the following Marcus Loew theatres: Metropolitan, Memphis; Grand Theatre, Atlanta; Vendome, Nashville; Knoxville, Knoxville ; also the D. W. Griffith studio at Larchmont, N. Y. ; the Stratford Theatre, Chicago; the Howard Theatre, Atlanta; and Saenger Theatre, Shrevesport, La. Jim Milligan, who quit the World to become a Typhoon fan, has promised to send diagrams of the above installations as soon as he can get down to a forty-four hour week basis for himself. They will be worth studying by our readers. Wants Heating Dope. Moving Picture World: This spring I contemplate the construction of a new theatre and am anxious to obtain suggestions from you in regard to the most practical heating plant to install. The auditorium will measure about 48 feet in width, 150 feet in length, and 29 feet in heights. At the front of the building there will be a lobby measuring 14 feet by 44 feet, and two stores, each 17 feet by 44 feet. Over each store will be offices of the same dimensions, which will require heat during the winter months. The seating capacity of the theatre will be at least eight hundred (800). I am taking the liberty of asking you for suggestions before placing my order for a furnace or boiler. William Smalley. Your auditorium would contain 208,800 cubic feet, the stores and offices, presuming that their ceilings would be 10 feet in height, would add 29,920 cubic feet, making a total of 238,720 cubic feet to be heated. Basing the heating ratio at 1 to 100, this would call for about 2,000 square feet of radiating surface for the auditorium and about 300 square feet of radiating surface for stores and offices. But you must take into consideration the fact that your ventilating system will change the air in cold weather at least four times per hour, thereby quadrupling the drain on the steam pressure through condensation in the radiators. To care for this, your boiler must have a steam generating capacity of approximately 8,000 square feet for auditorium and 300 square feet for offices and stores. Tliis calls for a total boiler capacity of 8,300 square feet. To Be Safe. To be on the safe side, a capacity of 9,000 cubic feet for the boiler would be advisable. Then you can take care of extraordinary conditions and warm the lobby at times, which has not been figured in the requirements. But do not make the mistake of figuring your heating installation cost on a fixed price or a competitive basis. Make up your mind as to the outfit that will actually heat your house and have some capacity in reserve and have your heating contractor and the manufac turer guarantee the results. Do not expect either heating contractor or manufacturer to work some magic by which a small plant will be fooled into doing the work of a large one. And do not make the bid competitive. If you insist on installing a plant too small for the requirements, you cannot expect a contractor to turn down the order. It's more than human to refuse to sell a wise guy a substitute after he has refused to pay for the real thing. A reputable heater builder knows what his plants will do. He will not deliberately sell you too large a plant. He certainly does not want to raise up a kicker in your territory by selling you one that is too small. Let him advise you. Then place your order with the heating contractor and see that you get the make and size that you specify. Can Any Reader Help Him?
