BY DAVID S. HULFISH THOSE who are familiar with the mechanics of picture making and the handling of film will find some devices of especial interest among the recent patents. Exhibitors will be particularly interested in the theater plan — No. 1,166,701 — which allows two audiences to see the same pictures. Nos. 1,165,146 and 1,165,147. Projector. Issued to J. T. Wells, assignor to Edwards Manufacturing Co., Cincinnati, Ohio. The complete projector comprises front and rear parts, the rear unit carrying film reels, intermittent mechanism and film gate, and the front part carrying lens and shutter and being movable for framing the picture. The form of the assembly is such that the one device may be used by amateurs as a camera, a printer, and a projector. 1,165,513. Shutter. Issued to Leo Kamm, London, England. The shutter is constructed as a fan to drive air against the film in the film gate. The film feed may be discontinued and the shutter alone may be run. 1,165,629. Film-Loop Device. Issued to Eberhard Schneider, New York, N. Y. (Application filed May 18, 1910.) The upper and lower feed sprockets revolve at varying speed to reduce the maximum feed loops. Spring pressed arms then keep the film taut in the loops between sprockets. 1.166.120. Convertible Kinemacolor Projector. Issued to W. F. Fox, assignor of part to Kinemacolor Co. of America, New York, N. Y. The Geneva gear has two pins, one of which may be rendered inoperative. When both pins operate, the film moves at double speed for color projections, the steady feed speed being changed also by dependent mechanism. 1.166.121, 1,166,122 and 1,166,123. Kinemacolor Slow Films. Issued to Wm. F. Fox, assignor to Kinemacolor Co. of America, New York, N. Y. The title "Kinemacolor Slow Film" has been used in this review because the film covered by these patents is a film for projection in an ordinary projector at the usual speed of projection instead of at double speed as has been required of Kinemacolor film as publicly used up to the present time. These three patents are patents upon the processes of making the new color film. The finished film is coated upon both sides, the red image upon one side of the film just matching the green image upon the other side, the images carrying their own color and no color screen or color shutters being required. This invention promises mUv.h for the future popularity of Kinemacolor, as it presents the Kinemacolor film in m u form available to all exhibitors and to all film exchanges, without the handicap of a special projector. 1,166,453. Intermittent Movement. . Issued to Leon Gaumont, assignor to Societe Etab. Gaumont. Paris, France. The Geneva movement is used, with this modification: The pin is withdrawn from the face of the pin wheel half the time and the star wheel shifts only on alternate revolutions of the pin wheel. The pin wheel runs at double speed and the \ . 1,167,8541 (i new intermittent mechanism, is at the top; then, reading down, comes 1,168,086, mi intermittent and framing device; 1,165,629, a fan shutter; and 1,169,097, arrangement for perforating prints.
