Q. Will you please now describe the essential characteristics of the projecting machines that were in commercial use or on the market at the date before mentioned, for projecting pictures of motion picture strips such as you have described. A. All such projecting machines embodied the following common characteristics. They were all adapted to use a single flexible transparent or translucent tape-like film such as I have already described. They embodied upper and lower supports for the bulk of the film. They embodied two feeding mechanisms, one consisting of a pair of continuously rotating sprocket feed wheels positively engaging the film, and having an intermediate section of slack film between them. The other feeding device, consisting of a feeding device that positively engaged the slack portion of the film and fed it with an intermittent motion at a high rate of speed across a fixed illuminated exposure window in such a manner that the intervals of pause and illumination exceeded the intervals of movement. These machines possessed a single stationary lens, and a shutter adapted to intercept the light during the period of movement of the film, and one or more times during the period of rest. These machines also possessed a movable frame carrying the intermittent feeding device and the slack portion of the film, the frame, the feeding device and the film being capable of adjustment with reference to the fixed exposure aperture.
Q. Was there upon those projecting machines, any framing device? A. Well, in describing a movable frame having thereon the intermittent movement and the slack portion of the film, which framing device was adjustable with reference to the fixed exposure aperture, I meant to describe a framing device. Perhaps my language would have been more descriptive if I had said that this frame possessed means of varying the relative positions of the feeding device and the slack portion of the film with reference to the fixed exposure aperture, that arrangement constituting a framing device, so-called.
Q. State whether or not there have been any projecting machines in commercial use in this country from the beginning of 1908 down to the present time, that did not
