October 1, 1927 EXHIBITORS HERALD 55 New Film Gate Gives Added Protection ( Continued from page 37) shield, gate latch, insulated trip lever, gate stop and film pad plate assembly. This plate is interposed between the front plate and the film pad plate in such a manner as to insure at all times a constant flow of cool air rising between the front plate and the rear plate and also between the rear plate and the film pad plate. By this means it is possible to keep the film pad tension springs at a temperature considerably below the point at which they would lose their temper and at the same time keep the rear plate and the entire assembly at a much lower temperature than the front or support plate. H — Air space between G and T. I — Air space between G and C. J — Front plate (radiating and insulating heat shield). This plate is scientifically designed to eliminate warpage under severe heat and is a support for the entire gate structure. K — Upper heat insulating cap. This cap is made of bakelite and is entirely insulated from the metal front plate, eliminating the possibility of the projectionist burning his fingers. L — Insulated gate latch lever. The gate latch lever is positive in action and is insulated with a bakelite trip, thereby protecting the projectionist from the heat when opening the gate. M — Light shield to protect the projectionist’s eyes from the intense spot on the aperture. This shield may be readily attached and detached. It is not fastened in any way. N — Fire shutter pivot pin. This part entirely new in design lifts or lowers the fire shutter perfectly freely at all times, there being no danger of its becoming bound in the bearings. O — Lower heat insulating cap. This cap also is of bakelite and entirely insulated from the metal front plate. It is an assurance against discomfort to the projectionist and the film coming in contact with any hot metal part. P — Lower loop protector. This newly designed assembly is self-locking and is so constructed that it opens downward rather than laterally as in the former design. The latch is so placed that it falls readily over the index finger of the projectionist when his thumb and index finger are engaged with, the knob to open the shield. The shield proper is maintained under slight tension so that it may be operated at will but without the slightest noise. Record of Five Days Made in Installing of Electrical Equipment Installation of the electrical equipment in Grauman’s Chinese theatre was made in the record time of five days, according to the Westinghouse company, manufacturers of the electrical equipment installed. Behind the record is this story : It was found, six days before the opening of the theatre, that the room for the generating equipment had been made too small. With this serious situation facing the management, the Westinghouse company was given an unlimited overtime order to completely install the equipment. To accomplish it the company’s service crew worked 24 hours a day for five days. The Chinese equipment serves a dual purpose. One set supplies power for the projecting arcs and the other acts as an emergency.
