No. 31079.—26th March, 1912.—JAMES AUGHILTREE CAMERON, of 61 Poplar Street, Brooklyn, New York, United States of America, Manufacturer. Moving-picture machine.

Claims.—(1.) In a moving-picture machine having an exposure-opening, a film-retarding device, and film-advancing means potentially capable of advancing a greater amount of film past the exposure-opening during each cycle of the machine than the amount of film actually to be advanced, acting to produce a slack in the film after each film-advancing movement, and then acting in opposition to said film-retarding device to remove said slack and irregularities in the film prior to the next film-advancing movement. . . . (4.) In a moving-picture machine provided with an exposure-opening, the combination with a device adapted to take up a definite amount of film during each cycle of the machine, a film-retarding device adapted to hold the film with sufficient tension to prevent movement thereof while any slack and irregularities therein are removed by stretching it, and a film-advancing member located between the retarding take-up devices and potentially capable of advancing a greater amount of film than that taken up by the take-up device during each cycle of the machine, whereby the film-advancing member will, during the first part of its movement, intimately engage said film to take up the slack and place the film under tension, thereby removing irregularities therein, and when the film is thus under tension will act to advance the same during the second part of its movement.
