Phe public is warned against purchasing or using infringing apparacus, POWER S CAMERAGRAPH No. 8) Introductory OWER’S CAMERAGRAPHS were first offered to the public some nine years ago, about three years after moving picture machines became generally known and used. In this period they have steadily advanced in popularity and reputation until the Cameragraph is now universally recognized as the best moving picture machine in the world. Though selling at a higher price than any other widely used machine, it has gradually supplanted other machines inthose sections where competition in the moving picture business has made the use of high grade apparatus neces- sary, and it is today the standard moving picture machine of all the leading lecturers and of the finest moving picture theatres. This success has not been a haphazard product of circumstance, but is the result of a consistent and uninterrupted policy of manu- facture. From the first, it has been the aim of the makers to produce the best machine possible, regardless of cost or margin of profit; the material used in its construction has been selected with regard only to its suitability, and every detail of construction has been watched with painstaking care. But this is not all that has made for the success of the Power’s Cameragraph. It has led the way in improvements, and in it nearly every substantial im- provement in moving picture projecting machines made in the past nine years has been presented to the public. The balanced rotating shutter with one narrow and one wide wing, the sliding framing carriage, the fire proof film magazines, the automatic fire shutter, were all first offered to the public in Power’s Camera- graph, and later appeared in modified forms in other machines. ‘Imitation is the sincerest flattery.” POWER 5S CAME RAGRERA PH No. 6 Power’s Cameragraph in 1908 As presented to the public today Power’s Cameragraph em- bodies all the results of nine years of close study and experience in construction. Repeatedly improved by new inventions and ad- vaneed methods of construction, it is characterized by the finest workmanship, accuracy of construction, interchangeability of parts, the highest grade of material, symmetry, compact- ness, portability, marked durability and fine finish. In its projecting quali- ties, it stands alone, projecting clear, steady, brilliant pietures, free from flicker, which do not weary the eyes of spectators after hours spent in watching them. POWERRKR S$ CAMERAGRAPH No. G The mechanism is the most distinctive element of any moving picture machine, and in the Cameragraph it is characterized by many features of significance. In Fig. 2 and Fig. 3, the mechanism, which is known as the No. 5 model, is illustrated as equipped witha reel hanger for sup- porting the upper or supply reel of film, and with a take-up device upon which a reel is mounted to take up the film as it comes from the mechanism. When thus equipped, the mechanism issupplied with three — sprockets for feeding the film. The upper, or , ““feed’’ sprocket, turns continuously | and unwinds the film from the sup- ply reel. The mid- dlesprocket moves intermittently and is consequently ¥ known as the inter- mittent sprocket, This spocket moves film downward from a loop formed by the feed sprocket and across POWER S CAMERAGRAPH No. 8 —ncicasenemansnsttataanmanaasananntttntititnatate the projection aperture, allowing the film to stop momentarily, after each picture on the film is brought before theaperture. The movement of the intermittent sprocket is effected by a star wheel, or Geneva stop, with four slots and a cam wheel with one pin, by which the period of exposure of each picture is made three times as long as the period of movement between exposures. This in- sures a flickerless picture without causing severe strain on the film. The third, or take-up feed sprocket, turning constantly, feeds the film to the take-up device and prevents the take-up device from pulling the film on the intermittent sprocket. The revolving shutter by which the light on the screen is cut off during the movement of the film, is of the balanced type, which has been extensively copied in other machines, since it was first brought before the publie in the ‘‘ Cameragraph.’”’ This shutter is mounted in close proximity to the steel aper- ture plate against which the film is held during exhibition, thus making it possible to use lenses of very short focus. The framing mechanism is distinctive and comprises a small carriage mounted on the main frame of the mechanism and ar- ranged for vertical sliding movement. Theintermittent sprocket, star wheel and pin wheel are all mounted on this carriage, which can be shifted by means of a short lever which has a toggle joint connection with the carriage. An ingenious arrangement of gear- ing is provided by which constant gear connection is maintained between the crank shaft mounted on the main frame of the ma- chine and the spindle of the sprocket wheel, which is mounted on the framing carriage. As the framing carriage is light and easily moved up and down by means of the framing lever, the framing of the picture in the projection aperture can be effected instantly and without imparting vibration to the mechanism or the stand up- on which it is mounted. The sprockets for feeding the film are all of steel, accurately cut and ground, the intermittent sprocket be- ing especially worthy of mention on account of its extreme light- ness, combined with great strength. The lightness of this sprocket is of obvious advantage in the operation of the mechanism on ac- count of the small momentum developed in it at each impulse from the pin wheel. POWERK 5 CAMEKAGRAPH No. 9 The tension rollers, by which the film is kept in proper en- gagement with the feed sprockets, are all mounted in pivoted brackets, controlled by springs, and are provided with set screws by which the tension rollers and sprockets may be accurately ad- justed so as to insure proper engagement of the film with the sprocket's with a minimum of wear upon the film. The aperture plate is of mild steel, punched out with dies to present an absolutely uniform aperture, and is provided with hard- ened steel guide strips on its face which insure the greatest pos- sible durability. The arrangement of the gearing of the mechanism on the left side of the mechanism places it out of the way of the operator. On the right side of the mechanism a shield or casing is provided to cover the rotating shutter and protect it from injury. To prevent over heating of the gate or door between the film and the light, a heavy cooling plate of brass is supported on the door to receive the light. This cooling plate is held a quarter of an inch from the door and its action is thoroughly efficient. A readily adjustable stereopticon attachment is provided on each Cameragraph mechanism. This can be supplied to carry a quarter size or half size lens, as desired. The Reel Hanger The Reel Hanger (Fig. 4) is at- tached toa bracket which is clamped to the top of the mechanism by the thumb serews provided for the purpose. It is equipped with a winding crank for the rapid re- winding of the film, either from a film bag or Take-up Device (illus- trated in Figs. 2 and 3, and sub- sequently explained). The reel is 10 inches in diameter and capable of holding 1000 feet of film.
