The film daily year book of motion pictures (1928)

have some managers been satisfied with the performance of the first set of covers for summer use, that they have ordered other sets for use during other seasons of the year. There are two distinct applications of chair covers, one of them is for the Durpose of transforming the theater interior to coincide with the climatical conditions, the other is for the purpose of covering up the sad dilapidated parts of the old scarred chairs. In the matter of the last instance, wonderful results have been accomplished with the minimum of expense. Theaters that first lost their drawing card because of the unsightly appearance of the chair backs and upholstery, have been brought back to the public favor through the judicious application of chair covers. There are several points that should be considered in ordering or selecting chair covers. For one thing the prospective purchaser should remember that auditorium and balcony chairs as a rule require two distinct and different styles of chair covers. A most important point, if the purchaser is to be satisfied, is the fact that chairs of the same appearance vary somewhat in size. If the chair covers are to be a good fit. last long and look well, they should be made to fit each individual size of chair back. # # * NUMBER OF IMPROVEMENTS MADE IN MOTIOGRAPH DURING 1927 By O. F. SPAHR President, Enterprise Optical Co. TURNING back the page? of history to 25 years ago, we find that the first projector made, weighed about 16 pounds and consisted of hardly more than an efficient magic lantern. Comoare that with the standard projector of today CThe Motiograph weighs approximately 600 pounds) and one is amazed to note the development in this type of machinery in so short a time. This progress may be accounted for, in a large measure, to the demands of this age. We are passing through an era, in all fields, of the keenet competition that this country has ever known. Many improvements were brought out on our * * Motiograph DeLuxe during 1927, which have been thoroughly tried out and not only have they added greatly to the efficiency of the equipment but they have aided in enhancing it to the trade. The most important improvement is embodied in our double-bearing ball-bearing intermittent movement, which was introduced early in 1927. This is an exclusive Motiograph feature, it being the only double-bearing ball-bearing intermittent movement on the market today. Its great value lies in the fact that not only is it responsible for the projector operating more smoothly, but it has increased the life of this vital unit some three or four times over that of the ordinary single bearing intermittent movements in general use. This unit has been further improved in that its bearings are now made of a special bronze, which reduces the possibility of the movement freezing, to practically nothing. Being thoroughly convinced of the value of hardened parts, we are continuing to harden the Motiograph star, sprocket, etc. which go into the Motiograph movement, because our experience has proven that this adds to the life of the movement. A new type of lens barrel was introduced in the early part of 1927. This is so arranged and built so as to hold the lens rigid and positive. Another Motiograph improvement born in 1927 is our quick and handy tilting device, which enables the operator to raise or lower the picture on the screen, with ease. This attachment was developed to meet the requirements of houses that find it necessary to use two screens, it becoming necessary during the performance to super-impose the picture from one screen to another. This can be done simply on the Motiograph projector by turning the hand wheel on the side of the projector which is most convenient for the projectionist. The year 1927 also saw the development of the new method of framing (on the Motiograph) by hand wheel instead of the lever. The hand wheel niethod is more convenient than the lever type ; it is _ conducive to smoother operation, eliminating the jerky motion heretofore experienced, with the old method of framing. With the hand wheel, the trouble of framing the picture past the mark on the screen is also eliminated. * Motion Picture Text Books (Names of Authors and Publishers of New Technical Film Publications) AMATEUR MOVIE CRAFT, by James R.
