CHARLES IVHITNEY, OF CHICAGO, ILLINOIS.

PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 446,372, dated February 10, 1891.

Application filed February 3, 1890. Seiial No. 339,090. (No 111 1 1,) Patented in Italy April 29, 1890,1T0. Z7,256,'338; in Canada July 2,1890, No. 34,607, and in France July 17, 1890,1T0. 20 M797.

T coZZ whom it may concern:

Be it known that I, CHARLES IVHITNEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Photograpmic Cameras, of which the following is a specification.

I have procured Letters Patent in the following-named foreign countries under the dates given upon this invention, to wit: in France, No. iii-M97, dated July 17, 1890;

in Italy, No. 27,956/333, dated April 29, 1800,

and in Canada, No. M4307, dated July 2, 1890. My invention relates to im 'irovements in photographic cameras, in which a series of negative-plates in ribbon form are used; and the objects of my improvements are, first, to provide means for closing or compacting a camera-box that it may occupy the least possible space; second, to provide a simple and convenient stop for time exposures; third, to provide means for connecting or attaching the end of the negative-ribbon to the windingpost, and also in the general construction and style of the camera-box. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of camerabox closed. Fig. 2 is a perspective view of camera-box opened. Fig. 5 is a cross-section of Fig. 1. Fig. lis a cross-section of Fig. 2. Fig. 5 is a modification of Fig. i. Fig. 6 is a modification of Fig. Fig. 7 is a plan view with cover removed. Fig. S is a detail of shutter showing time-stop. Fig. i) is a detail showing manner of attaching the end of the negative-1ihbon.

Similar letters refer to similar parts throughout the several views, in which A and B are cover-boards, and C and D are the telescopic frame.

E is the time-stop button.

F is the lcnsaperture.

Gr is the spring time-stop.

ll is a slotted tube containing the coil of negative-ribbon I.

K is fastener holding the end of negativeribbon to the connecting-strap.

J is a connecting-strap.

L is a flexible V-frame.

M M are the spring-stops to the telescopic frame.

N is the winding-post.

O is the lens.

I is the ribbon in fastener K.

R is the tube-support.

O is a flexible frame.

M is knuckle-joint hinges.

A and B are top and bottom covers.

P P are catches to top and bottom covers.

S is a clasp.

T is the supports for the V-sl1aped frame.

In shape my camera may represent a book when closed, as in Fig. 1, or a porte-monnaie, as shown in Fig. 5, or it may be'a plain box of any suitable material.

In Fig. 2 my camera-box is represented open ready for an exposure. It will be seen that by pulling out the top 13 until the springcatches M stop the movement by dropping into notches provided for them the opening of the camera is very easy and simple.

As shown in Fig. 3 the box is closed, and in Fig. 4 it is drawn out.

In operation thetop and bottom covers may be removed, as they are fastened either by screws or spring-catches. (Not shown.) Atter the covers have been removed then place the slotted tube II (containing the negativeribbon) into place, as seen in Fig. 7. The

loose or outer end of the ribbon projecting through the slot of tube H is passed around posts T T of the V-shaped frame and connected at K. This is done bysliding the end of the negative-ribbon into the slot of the metal hook K and doublingitdown, as shown at I in Fig. 9. Next I replace the covers A and B and draw out the telescopic slide to its full extent, which operation draws the negative-ribbon straight. The convex side of the negative-ribbon being next to the cover A, and the other side of that portion of the ribbon which is in place for exposure being held close to the cover A by the posts T T, which constitute the end of the V-shaped frame, in this manner the ribbon is held secure against buckling. (In a previous application I have shown a sh utter which may be used with this style of camera, and the same is partially shown in Fig. 7 of this application.) My

camera being now adjusted for an exposure,

I point the lens toward the object which I wish to photograph and operate the shutter when the exposure is made. Should it become necessary 'to make a time exposure, I have in this camera provided a spring-stop G, as shown in Fig.8. 3y pressing upon the button E the shutter-slide is arrested in its movement at the time the hole in the slideis opposite the lens. Thus any desired time may be given for an exposure, and when the pressure is released on button E the shutterslide is permitted to cover the lens. After an exposure has been made the exposed part of the negative-ribbon is wound up by turning the post N, which is done by inserting a key in the square hole of post N. 5 at letter U.) While an exposed negative is being wound up enough negative-ribbon for another exposure is being drawn from the tube H for another exposure, and the pos tion may be determined by a colored-glass peephole, as shown in one of my previous applica tions.

To permit my camera to be closed to the smallest capacity possible, the same principles are used as shown in my previous application, viz: a V-shaped light-tight frame inside the camera-box, so that the tube of negative-ribbon and the winding-post may be placed close to and on each side of the lens. In my previous applications I have shown a rigid V-shaped frame; but for the purpose of economizing space I make a flexible Vorfunnel shaped frame, as shown in Figs. 3, 4, and 6. Any flexible light-tight material may be used, or hinged rigid pieces may be used, as shown in Fig. 0 at L L I. L, and to make the V-shaped frame secure from light I cover the top and bottom with cloth of any suitable light-tight quality. For this purpose I use rubber cloth.

, In the use of the variouskinds of negatives in ribbon form there is more or less waste necessary in taking negatives out for development and attaching the end of the ribbon to the Winding post or spool. Inmy invent-ion I obviate nearly all of this waste by attaching to the Winding-post a thin flexible strap 7 or cloth, to the loose end of which I attach a thin metal hook-shaped fastener, as shown in Figs. 4 and 9.

In Fig. 5 I have shown a flexible connection or outside frame (marked 0) and knucklejoint hinges m m to hold the covers A and B extended for exposure when drawn .out.

(Shown in Fig.

In this I obtain more compactness when the case is closed.

In Fig. 5 the covers A and'B' are hinged at the back side of the box, as shown in the drawings, and held by-spring-catches P P at the front side, and when the case is closed it is held together by clasps.

What I claim as my invention, and desire to secure by Letters Patent,is 1. A photographic-camera boxof bookform constructed with telescopic joints and a flexible V-shaped compartment, through which the exposure is made, substantially as described.

2. A photographic-camera box composed of the covers A and B, the telescopic frame 0 and D, and the spring-stop M, substantially as described.

3. A photographic camera in a box or book form constructed with covers A and B and telescopic frame 0 and D with the inner lighttightcompartment,substantially as described.

4. In a photographic camera, the telescopic box, the flexible funnel-shaped light-tight compartment, and the separate compartments each side the lens for storing the negativeribbon, substantially as described.

5. In a camera, a flexible V or funnel shaped compartment- With a lens at the apex and the negative-ribbon across the base, with the storage-compartments each side of the apex of said frame,and the cover A,holdingthe negative ribbon straight, substantially as described.

6. A photographic camera constructed in book form when closed, provided wit-h a telescopic frame with attachable and detachable covers, and means for holding the frame in place when drawn out, substantially as described.

7. In a photographic camera, the slotted tube H, the flexible frame L, the negativeribbon I, and the winding-post N, substantially as described.

8. In a photographic camera using the negatives in ribbon form, the connecting link or strap J, the post N,and the means for attaching the end of the ribbon to the strap, comprising a hook-shaped fastener K, having a single lap, whereby when the connection is made the fastening is a plain lap-seam joint, substantially as described.
