GEORGE FREDERIC HATTON, OF ST. LEONARDS-ON-SEA, ENGLAND.

KINEMATOGRAPHIC APPARATUS.

SPECIFICATION forming part of Letters Eatent No. 713,876, dated November 18, 1902 Application filed August 11, 1902.

1'0 [0% w/tom it may concern:

Be it known that I, Gnonen FREDERIC HAT- TON, a subject of the King of England, residing at St. Leonards-on-Sea, Sussex, England, have invented certain new and useful Improvements in or Relating to Kinematographic Apparatus, of which the following is a specification.

The present invention relates to kinematographic apparatus, the object being to provide a machine which will successively change the sections of a kiuematographic film in a rapid and simple manner, the mechanism being entirely driven from one shaft without employingspurorothergear. Theapparatus can be adapted either for taking or exhibiting kinematographic pictures.

In the accompanying drawings, Figure 1 is a perspective View of the film-operating mechanism according to this invention, part of the casing being removed; and Fig. 2 is a transverse section of the apparatus on the line 2 2 of Fig. 1.

Like letters indicate like parts throughout the drawings.

Referring to the drawings, the casing A carries a film-spool B, from which passes a series of pictures, transparencies, or the like or a photographic film G, adapted to receive a series of pictures. The film O is fed into the apparatus at uniform speed by a constantly-rotating roller D, against which the film is pressed by a roller E. The roller D is formed on the axle F, and its circumference is arranged to be equal to the width of one picture-section, and thus one picture is passed through at each revolution of the axle F, which is driven by a pulley G through a belt J, passing around a driving-pulley H, having a handle H, or the shaft )3 may be driven in any other convenient manner.

The pressure-roller E is carried by a bellcrank lever E, pivoted at E and is normally held against the film O by means of a spring E and in order to regulate the pressure of the roller E, and consequently the rate of feed of the film C, the tension of the spring E may be slightly altered by means of a pivoted lever E, attached thereto.

The necessary intermittent movement of the film at the exhibiting or exposing point is eifectedby intermittently drawing or jerk- Serial No. 119,331. (No model.)

ing the strip or film a distance corresponding to the width of a picture-section. The intermittent movement or jerk is accomplished by a constantly-rotating arm K, carrying a gripper L, which is so guided that during a portion of its path it is in contact or engagement with the film C and imparts to the latter the necessary movement. The gripper L engages the film at both edges and is provided with frictional gripping material L which engages the film.

The guide comprises a rail M, suspended from the casing and arranged to lead the gripper L into and out of contact with the film at the necessary positions. The gripper L is pivoted to the arm K and carriesa finger L, which is kept pressing against the guide-rail M by a spring K, having an adjusting-screw The film having been guided past the exhibiting-point by suitable means passes over a friction-roller N, and the guide-rail M terminates a short distance on either side of the roller N, and the gripper L therefore leaves the rail and presses the film C against the roller N and pulls the film through the guides to an amount approximately equal to the width of one picture-section. The guides for the film consist of metal plates 0, between which the film passes from the roller and by which it is brought into proximity with the roller N. The side of the guide-plates which is in contact with the emulsion on the film is cut away in the center in order that the metal may not damage the pictures. At one end of the guide-rail ascrewed rod P is provided having an adjusting-handle P, by means of which the distance during which the gripper is in contact with the film can be adjusted. Normally the film is just out of contact with the roller N, so that the roller may continuously rotate, owing to the impulses imparted to it by the gripper L, and that the film may onlybe in contact with the roller while a jerk is taking place.

The film is more firmly held between the feed-rollers D E than it is by the gripper L, so that if the gripper be set to feed rather more than one picture the film will always be drawn tight, and the gripper will then slip over the film slightly. This slip can be made as small as desired.

In order to keep the film in proper relation to its guides, pads Q, carried on levers Q, may be kept pressing against the film by springs Q or the like.

A lens is disposed in front of the exhibiting-point R, and in the case of a kinematographic camera a suitable shutter is also provided. When the machine is employed asa lantern, the light may conveniently be reflected through the exhibiting-film by a mirror S, arranged at a convenient angle to the film.
