Movietone of Silent
E are advised that some exhibitors and pro
\ \ jectionists prefer that movietone have the same
screen image width and height as the silent pictures, rather than the regular movietone dimensions.
Well, why not? It is not in the least difficult. In fact right now the Roxy theatre, New York City, is projecting its silent pictures and its movietone at precisely the same dimensions. Roxy did not fancy the idea of having the movietone and silent pictures of the same height but of different width, so Arthur Smith, his Chief Projectionist, got himself all nice and busy and within a few days both pictures were the same size and the same dimensions. Roxy likes it! So, I think, would you. It is quite simple, especially if you have three projectors and use one of them exclusively for movietone. If you have but two, it can be done just the same, only there is a slight added complication.
Desi6nNeD BY ARTHUR J. SMITH,
After examining the plan worked out by Chief Projectionist Arthur Smith, I was so impressed with its practicability that I immediately took the matter up with Mr. Michel, General Manager Simplex Division International Projector Corporation, and they are now working on a special aperture, which will

be available very soon. I also suggested to Mr. Michel that a special lens mount be designed so that the projection lens might be instantly detached or attached, without the formality of screwing it into or out of the mount. I understand that this also will be done. If it is, then the change from silent pictures to movietone, both of the same size and dimensions as to screen image, should not consume to exceed five, or at most ten seconds.
Here is the plan as worked out by Chief Projectionist Arthur Smith of the Roxy Theatre. Take the accompanying diagram, together with a Simplex aperture plate to any competent machinist and have him cut the slot in the plate as indicated in diagram. Mark you well, however, this is not a job for a blacksmith, though any competent machinist can do it.

Having finished the slot, let him make, from any suitable sheet material, a metal slide to fit snugly into the slot. It must fit closely, but not bind. This slide, in its finished form will be an aperture mask. In fact, it will form the actual projector aperture opening. It may be made long enough to contain an opening at either end, one for movietone and one for silent pictures.
