PHOTOGRAPHBC CAMERA.

SPECIFICATION forming part of Letters latent No. 582,855, dated May 18, 1897.

Application filed January 13, 1897. Serial No. 619,054. (No model.)

To aZZ whom it may concern.-

Be it known that I, ERNEsT R. FREEMAN, a citizen of the United States of America, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Photographic Cameras; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to make a simple and economical plate-holder holding four dry plates or films to work in connection with a slide or collapsible cover containing the lens and shutter, these being the objects most sought after in the articles of this description.

To these and other ends the invention consists of certain novelties of construction and combinations, all as will be hereinafter described, and the novel features pointed out in the claims of this specification.

111 the drawings, Figure 1 is a perspective view showing the camera ready for transportation. Fig. 2 represents a perspective view of the camera-box, the front wall, which carries the lens and shutter and the light-excluding boX or slide, being removed and the side of the camera-box being broken out to showthe rotatable plate-holder. Fig. 3 represents a perspective view of the light-excluding box or slide. Fig. 4 represents a perspective view of the plate-holder. Figs. 5 and 6 represent different perspective views of the plug for rotating the plate-holder. Fig. 7 represents an elevation of the shutter and its supportingplate.

Similar reference-characters indicate the same or similar parts in all the views.

lVithin the camera-box A is rotatabl y mounted the plate-holder B, which is preferably a cube formed of any suitable light framework or material and having four equal sides, each of which is provided with plateholding strips 0 at the top and bottom.

An angular plug D is provided with a circular portion which fits an opening N in the Wall of the camera-box and with a wing or rib by means of which the said plug may be rotated. Said angular plug fits a similarlyshaped socket F in the top of the plate-holder, and an arbor E at the center of the bottom of the plate-holder fits a suitable bearing in the camera-box opposite the opening l G represents a movable partition having an opening to expose a plate, said partition forming the rear portion of a slide, which in this instance is represented as a box II, having its front wall provided with flanges K, which overlap the front edges M of the camera-box. This slide or box as a whole is of such length that when pushed inward until the flanges K are in contact with and overlap the edges M and exclude light from leaking past the outside of the slide the partition G is at that time in contact with the plate or the strips 0. The said sliding partition G therefore insures the plate being held at the proper angle to receive the exposure, and at the same time it prevents light from affecting the plates which are on other walls of the plate-holder. By drawing the box or slide H slightly outward the plateholder is free to be rotated by the plug D, and on returning the said box or slide the proper plane of the next plate is insured. I thus avoid the necessity of any detent or stop devices for determining the position or plane of each plate in turn.

The plate 0, which may be the front wall of the boX or slide H or a plate attached to such front wall, is provided with a lens or lens-opening, as indicated at U, and with the shutter P, said shutter being pivoted at TV and provided with an elongated curved exposure opening or slot R and with an operating-handle or finger-piece S. Suit-able pins or stops V are provided to limit the movement of the shutter, and a friction clamp or catch T is connected to the plate 0 and overlaps the shutter and bears on the lower surface thereof with suflicient pressure to hold said shutter in any position in which it may be placed, the lower curved edge of the shutter being smooth or free from notches to interfere with the clamp T.

It will be readily understood that my camera, as illustrated and described, is exceedingly simple and may be constructed at a trifling cost.

Having thus described my invention, what I claim is 1. A camera comprising in its construction ICO a rotary holder having means for supporting individual sensitive plates or films, and a boxshaped slide or partition adapted to be moved to and from said holder to retain it in position or release it therefrom.

2. A camera comprising in its construction a rotary holder having means for supporting individual sensitive plates or films, and a boxshaped slide or partition adapted to be moved to and from said holder to retain it in position or release it therefrom, said box-shaped slide having a front portion carrying a lens and shutter.

3. A camera comprising in its construction the boX A having an open end and containing a rotary plate-holder, and the box II fitted to slide Within the open end of box A and having the rear Wall G provided with an opening and adapted to bear against one of the sides of the holder, said box II having also front flanges K to overlap the edges M of the camera-box.

l. The combination with the camera-box A, of the plate-holder B having a plurality of plate-holding sides and having the arbor E and angular socket F, and the plug D hav ing an angular portion fitting said socket F and having a circular portion fitting a eircnlar opening in the camera-box.

In testimony that I claim the invention set forth Within I have hereunto set my hand, this 12th day of January, 1897, in presence of two subscribing Witnesses,

ERNES" R. FREEMAN.
