Exhibitors Herald World (Oct-Dec 1929)

this lens is removed and the other one put in, but when this lens is reinserted, all that is necessary is to shove the clamping ring up against the front lens clamp, and the lens will be exactly in focus. Also you will observe almost in line with the top of the lens barrel, a rod which extends back through the casing of the rear lens clamp. This rod also extends forward into a hole in the ring we have been talking about. You will thus see that when this rod is in the hole, the lens must be in the correct rotational position for which it was previously set. Now we come to a very important phase of this whole proposition. You know sound caused projectionists to have one devil of a time keeping the picture in center on the screen when they changed, for example, from Yitaphone to Movietone. Looking at Figure 2, you will observe just above the lens extending to the right, a small lever. This lever is the boy that does the trick. As the lever now sets, the Movietone picture would be centered on the screen, and the optical axis of the lens would be exactly in the center of the Movietone aperture, which latter is controlled by means of a vertical sliding bakelite knob (shown just to the right and a trifle below the film gate knob). When this is shoved down, the aperture is right for film which carries the sound. Now if we move the bakelite knob up, which may be instantly done, and swing the little lever over the projection lens to the left, we shall instantlv have the 35-mm. film picture centered on the screen, and that's that. You will observe that this is a very nractical, clever arrangement. It does not involve any complicated objectionable ooerations whatsoever. It is just merely a matter of snapping a bakelite knob down or up, moving the lever, and the right result is obtained in just about one second of time. Immediately back of the framing knob is a snap switch by means of which a framing light is put into operation, which illuminates the aperture so that the film may be set exactly in frame. FIG. 4 December 28, 1929 The gate assembly is essentially as it was before, except that the film trap plate and the guide rollers, etc., are very, very much heavier than they were before. In Figure 3, we have a front non-operating side view of the mechanism enclosed in its casing. Beside the projection lens we see a handwheel, which is for the purpose of rotating the mechanism by hand should it be desirable to do so. Also you will observe that there is a framing knob on the non-operating side, so that the picture may -be framed from between the projectors if desired. I believe this covers the salient points of the new projector mechanism, but I may add that there is also a new stand now available which may be ordered with the new mechanism if desired. It will be known as the Type R Simplex pedestal (Figure 4). It is particularly desirable, in view of the fact that the turntable for disc records is located immediately beneath the lamphouse, and because with the multiplicity of projectors already in use, plus the possibility of more coming when wide film arrives, the matter of minimizing space between projectors is becoming of very vital importance, particularly in theatres where the projection distance is rather short. I might add in connection with this stand that the arrangement for tilting the projector is both excellent and convenient. You don't have to get a jackscrew to do it. It may almost be done with one finger, yet the instant the tilting wheel ceases to revolve, the projector is locked rigidly in position. The stand is equipped with six revolving screws, by means of which the revolving of the projector is conveniently accomplished. I might tell you considerably more about this new mechanism and stand but I hardly think it is necessary, with space at such a premium as it is at all times in this department.

Four Educational Comedies In Sound Help Colonial at Vancouver to B.O. Record (Special to the Herald-World) VANCOUVER, Dec. 24.— Four Educational sound comedies constituted the program at the Colonial theatre, and set a" record for box office receipts, according to Hector Quagliotti, owner. The program consisted of two Mack Sennett comedies, "The Big Palooka," co-featuring Andy Clyde and Harry Gribbon, and "Girl Crazy," with Andy Clyde and Alma Bennett, "Buying a Gun," starring Lupino Lane, and "Don't Get Excited," with Harold Goodwin, Addie McPhail and Lloyd Ingraham. Each was a two-reeler.
