ATTACHMENT FOR PHOTOGRAPHIC CAMERAS.

SPECIFICATION forming part of Letters Patent No. 443,555, dated December 80, 1890.

Application filed February 10, 1890. Serial No. 339,776. g (No model.)

' and to the letters of reference marked thereon, in which Figure 1 is a View of the rear end of a camera, showing it openand the blinds entirely closed. Fig. 2 is a detached side View of the cut-out plate, showing the blinds properly attached and open. Fig. 3 is a transverse section through line a: 00, Fig. 2.

The present invention has relation to attachments to photographic cameras; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all the figures of the drawlngs.

In the accompanying drawings, Arepresents the camera-frame, which is constructed in the ordinary manner and may be of any desired size.

The plate-holderB is located as illustrated in Fig. 1, and is constructed in the usual manner, reference being had to the size of the plate designed to be held.

The cut-out plate 0 is removably attached to the bars D, and is located substantially as shown in Fig. 1. This cutout plate 0 is provided with the apertures a, which apertures correspond in size and form with the photographs desired to be produced.

In the drawings four apertures are shown; but itwill be understood thata greater or less number may be used, if desired. It will be seen that if small photographs are to be produced the number of the apertures a may be increased, and if large-sized photographs are to be produced the number of the apertures will be decreased in proportion to the increase of the size of the photographs to be produced, regard being had that the same-sized camera is used in each instance.

The blinds E are held in the desired positions by means of the strips 1), which are located as illustrated in the drawings, and are attached to the barsD by means of the screws d or their equivalents. The bars D are provided with the ledges d, which ledges are for the purpose of receiving the edges of the cutout plate O, as illustrated in Fig. 3.

It will be understood that the strips 12 should be so adjusted that their inner portions will hug the blinds E, and thereby hold said blinds and the cut-out plate 0 at any desired point of adjustment.

In use the plate-holder B is placed in the camera in the usual manner and the camera properly adjusted upon the object to be photographed, at which time the blinds E are so adjusted that but one aperture a will be open, when the negative is produced upon the negative-plate in the usual manner. The plateholder 13 should be so adjusted that the first negative will be produced at one of the upper corners of the negative-plate proper, and when the first negative has been properly produced the plate-holder 13, together with the negative-plate, is moved to the right or left one of the stops f, at which time another negative is produced by the side of the first one produced, and so on until a full row of negatives have been produced across the top of the negative-plate, at which time the blinds E are so adjusted that the next lower or second aperture a will be open and the plateholder B adjusted to the point it was when the first negative was produced, and the second row of negatives produced, and so on until the negative-plate has been filled, or until the desired number of negatives have been produced.

It will be seen that the negative-plate may be filled with negatives taken from one ob* ject, or as many diiferent objects as negatives desired to be produced.

It will be seen that by mypeculiararrangement I am enabled to produce any desired number of negatives upon one negative-plate with the use of one lens, and that one adjust ment of the camera is all that is required for each horizontal row of negatives upon the negative-plate proper.

For the purpose of holding the cut-out plate 0 in proper adjustment the plate F is provided, which is held in the desired position by means of the notches g and the catches g or their equivalent.

In the event the negative is to be larger than the original or object it will be understood that a lens designed to enlarge should be adjusted in the camera, instead of a portrait-lens. In the event the negative is to be reduced in size the apertures a in the cut-out plateC are reduced in size and the camera properly adjusted as to distance. It will also be understood that different cut-out plates 0, having different-sized apertures, are used.

Having fully described my inventioinwhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a photographic cam era, the movable plate-holder 13, the cut-out AUGUST TS YIGNOS.
