A frank understanding of the liniitalions of alnio«i| e\erv type of continuous projector is important to the user. In the ca««i' of motion pictures, mechanical mechanisms must carry delicate film in continual motion and subject to varying degrees of temperature and humidity. W ilh these condition> anticipated, however, the user may derive both service and satisfaction.

Advita^jrapii Several years of intensive research preceded the announce. iiient of the Advitagraph Projector by its Louisville. Kenlucky manufacturer. Within recent months the company Ka be;:un ofTering it product lo advertisers anil dealers and Ibe important tests of actual held usage has apparently been passed. Advitagraph features a anlidrag film feed system (noted in th illustration > and an ind projection. Specially desif ■ pliBed le accompanying irror-sbutlle type of ;ned display cabinets are used Willi the projector unit. Prospective users may contact ihe Advitagraph Corp..

This motion picture projector automatically repeats a merchandising message as -.% movie within a store, store window or show room day • •r night. In the Merchandiser a simple piece of optical ;;lahs stops the image as the film reels smoothly and unhesitatingly along. There are no shacks or jerks. The use • >f this simple optical system reduces the normal inulli(ilicity of gears and claws to two simple spurr gears and ■ he u»e of oil-less and ball bearings eliminate the need of lubricating the machine. A major cost item, other than ihat incurred through the necessity to service inlermitlenl projeelors. is the lamp cost. The lamp used in the Mer.hanttiser is an ordinary 75 Watt, 100 hour lamp. Another unique feature is the removable magazine on which the film is received already to be inserted in the machine. There are two types of these magazines, one of which consists of simple wooden rollers which is so low in cost that the entire magazine, together with the worn-out film may be thrown away at the end of the run.
