The adoption of a paper tape or strip for projecting work necessitates the use of a somewhat different projecting machine, as the light cannot penetrate the paper film sufficiently to show the image clearly on the screen. Therefore it was necessary to invent a new illuminating scheme for this kind of work, and it was not long before Mr. Webb evolved one which has proved very successful. One of the latest type of projecting machines ma-chines is illustrated at figure 1. Its general gen-eral construction is very similar to the present pres-ent type moving picture machines, the only difference being that the film is illuminated as stated above. By referring to the first photograph it will be noted that the paper film is held on the top reel and is taken up on the lower one when in operation. Similar gears are used for feeding this photo strip, as in an ordinary machine. The source, of light is obtained from a number of incandescent electric bulbs, placed in reflectors and arranged ar-ranged in circular or ring form. This unit is placed in the circular chamber. cham-ber. The face of the bulbs is directed to-,ward to-,ward the paper film so that the light falling fall-ing upon it is reflected toward the projecting project-ing lens, which is stationed on the front of the chamber. A photograph showing the exact construction con-struction of the luminous unit is reproduced at figure 2. The central opening is used to permit the reflected picture to pass through and enter the projecting lens. The general operating principle of this machine is exactly ex-actly the same as that of a postcard projector, pro-jector, with which we are all familiar. The light is focused upon the postcard and reflected re-flected throagh the lens. It will be noted that, the general make-up of the projecting machine is just the reverse of the commercial commer-cial ones used today. The light is focused on the picture in the opposite direction to the projected image, while the light of the present standard machine is focused In the same direction as the projected screen. Figure 4 shows a different type pro-I'nctnf pro-I'nctnf intended Drima- rily for the home. The picture is focused on a transparent screen, the photo reel being operated oper-ated by a motor. The negative, which is the original photograph photo-graph taken of the moving mov-ing object, is first made on a regulation celluloid film and taken with a standard moving picture-camera. picture-camera. The construction construc-tion of the new instrument instru-ment is very simple, as seen from the accompany accom-pany 1 n g photograph. Standard motion picture pic-ture negative films are used, and the camera carries 100 feet of film, being so constructed that It may he loaded in broad daylight.

The connections are obtained by means of a flexible conductor, fitted with plug connectors at both ends. In this way it can be operated without a tripod, a great advantage in emergency use. After the pictures have been photographed photo-graphed upon the film the latter is developed devel-oped in the usual manner and the print is made upon a sensitized paper strip, which is used in projecting the picture on the screen. A sample of such a paper strip is shown as a border about the photos herewith. here-with. The general make-up is about the same as for regular movie films with the difference cited above. The amateur may now take his own pictures, pic-tures, print and develop them in his dark room and project them on his parlor wall.
