The Smith Portable Projector is described as a smooth-running machine. It is said to be a new type of motion picture projection machine whose mechanism is electrically operated and automatically controlled. It is equipped with a water-cooled condenser, and even though the light is unusually strong is said to be entirely free from heat. The "Projex" lens is said to merit special mention because of the sharp and brilliant definition of the picture when correctly adjusted to a projection machine. Eugene H. Kaufman, manager of Inter-Ocean's rapidly expanding accessory department, will be directly responsible for the sales of the new products. The Gillette Multiple Reel Machine Is Simple, Automatic and Time Saving THE Gillette multiple reel picture machine, or appliance, is a complete motion picture machine, with the exception and head and lamp house, and works in conjunction with any type of these. The features of the machine are the skeleton aluminum reels, the slip disc pulleys operating these reels, the variable speed starting device for the driving of projector, and the fireproof film guides. The skeleton aluminum reels weigh but three pounds each, have a large hub and a capacity of eight thousand feet of film. The film is taken from the shipping reel onto the lower reel and then reversed onto the upper reel ready for exhibition. After the full performance has been shown, the film is again driven into the upper reel ready for the ne.xt screening. This can be done during changes of audience. The reels are controlled by hand throt' ties operating slip-disc pulleys which have spring tension. The slip-disc pulleys serve two purposes, they drive the reels for rewinding and act as brakes for the reels from which the film is taken. While the upper reel is being driven for rewinding enough tension can be put on the lower one to keep the slack from the film and still not be rigid enough to break it. There is little danger of breaking the film if the pull is steady and no slack allowed. The same throttle that operates the slip-disc pulley driving the lower reel for taking the film from the shipping reels, gives the operator complete control of the l.ower reel while being used as a take-up, and can be adjusted while machine is in motion. By the use of this special type of slip-disc pulley it is never necessary to detach any of the belts, as the slip-disc runs free unless tension is put on it by one of the throttles. Has Variable Speed. The machine has a starting and variable speed device that is new to picture machines. This device is simple and never slips. It consists of a metal cone three inches long, two inches in diameter at the large end and one inch at the smaller end. This cone slides on a shaft with a key-way which is driven by the motor. On another shaft parallel with the cone is a leather disc % of an inch wide and 3 inches indiameter. The leather disc engages with the metal cone at the small end in starting, giving the projecting an easy start. Any speed desired can be obtained by sliding The Gillette Multiple Reel Machine.
