SUPPORT FOR DISK FILMS.

Specification of Letters Patent. P t t d D 12, 1916,

Application fled I1, 18, 1912, Serial Io. 896,998. Renewed my 16, 1918. Serial I0. 97,857.

To all whom it may concern:

Be it known that I, 151001: Krrsnn, citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Supports for Disk Films, of which the following is a specification.

My invention relates to an improvement in cinematography.

Its object is to produce new and novel means to support the picture plate or disk and means to bring the required picture on said plate or disk to view.

The great value of this, my invention, will be most apparent in such instances where pictures are produced on a comparatively small compass, as is practised in private or house exhibitions.

For the purpose of illustrating one form my invention may take, I have reference to the accompanying drawing.

In this drawing: Figure 1 is a front elevation of the film support and the means of securing the film to said support. Fig. 2 is a top view illustrating also the mechanism to move said support. Fig. 3 is a front elevation of the picture film or disk. Fig. 4 is a cross section of the disk, the support for same and the retaining wire ring and Fig. 5 a cross section and side view of the propelling gear and teeth of the disk support.

In these figures 1 is the rotating support or holder provided with the holes or windows 2, for the purpose of exposing to view the pictures printed on the picture film. The holes or windows 2 are here arranged in a spiral around its am's.

3 are projections, by preference, as illustrated in Fig. 1, punched from the disk portion of the support or holder adjacent to the picture holes, each forming a tooth and the whole forming a gear-like arrangement.

4 is a gear having the sides 5, rounded at 6, 6, and engaging the gear tooth 3; the gear tooth, or otherwise, provided for on the support or holder 1. The lamp box 8 with its light 9 is here provided with the lens tube 7 adapted to concentrate and throw the rays 0 of light through the holes or windows of the support onto that part of the film which brings the required picture to view.

10 is the picture film, here shown in the shape of a disk and provided with the pic tures 11. These pictures are also arranged here in the form of a spiral line coinciding with the spiral line of the windows of the disk is placed thereon and has the purpose of retaining the disk in its place.

13 1s a support having the rods 14 and 15 secured parallel to each other over which the block 16 moves and this block 16 supgfii'lts the holder or support for the picture The operation of the device is as follows :The picture disk 10 is placed on the support in a manner so that the picture deslgnated by the letter A should come in alinement with the window of the support designated by the letter A, and after the disk is 1n 1ts position, it is secured thereto, first, by wire ring and, second, by a set of washers and nuts, which are designated in the drawmg by the numeral 20. To bring the requlred pictures to view, it is only necessary that the gear 4 should be brought in rotat1on. Through its movements, the holder or support 1 is given a rotary movement and the curved sides of the gear 4 give a side thrust to the gear 3 and thus cause the spiral to advance, so as to bring successively successive pictures to view and in the focus of the lens 7 I have not illustrated here means to rotate the gear 4, as such means may be automatic or manual. I also have not illustrated here the required shutters and intermittent or Geneva movements, as these arts do not form part of my invention and are well understood by persons versed in the art, but it is obvious that when the pictures should be projected, the mechanism above described has to be provided with such accessories as are provided today for the successful working of moving pictures.

For the purpose of m invention, it is immaterial what type 0 shutter may be used, as long as the shutter works quick enough for my purpose and allows the light to strike the picture only when not in motion. For the purpose 0f my invention, it is also immaterial what nature of illumination is provided; it suffices to state that for a house or private entertainment, it is not required to be as intense as or public entertainment, for the reason that the length of ioo projection and diameter of increase is far less.

In the drawing, I have not illustrated the position of the Geneva movement as usually employed in moving picture machines, and for the purpose of my invention, it is immaterial if the intermittent movement is produced by such a Geneva movement, or by contrivances similar in their action. It suflices to say that such contrivances must be quick enou h and must allow the stopping of the picture holder at the required time.

lhe purpose of my invention is not to illustrate and describe a producing or reproducing machine for moving pictures as an entirety; its purpose is only to illustrate and describe means for protecting and supporting films used for such purpose and means to move, in conjunction with the sup! port, the picture film.

Having now described my invention, I claim as new and desire to Letters Patent is 1. In a device of the class described, a holder for a moving picture record mounted for rotation and simultaneous transverse movement, projections 61' teeth spirally arranged on said holder, and means fixed with what secure by relation to the holder engaging the teeth.

2. In cinematography, a disk-shaped holder for a picture film, a flange for said holder, a series of cut-out parts or windows in spiral form, a series of projections or teeth in spiral form.

3. In cinematography, a disk-like moving picture film, a series of pictures thereon spirally arranged, in combination with a holder provided with a series of cut-out parts or windows spirally arranged and means to move the holder for the purpose of bringing successively successive pictures to view.

4-. In cinematography, a holder for moving picture records of the disk type, said holder provided with spirally arranged prowindows.

In testimony whereof I afiix my signature in presence of two witnesses.
