MULTIPLE-EXPOSURE ATTACHMENT FOR CAMERAS.

Specication of Letters Patent.

Patented Dec. 31, 1918.

Application inea January 3, 1917. serial No. 140,405.

To all whom it may concern Be it known that I, ALFRED ANDREWS, a citizen of the United States, residing at Barnesville, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Multiple-Exposure Attachments for Cameras; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide an improved multiple exposure attachment for cameras, whereby various parts of the plate or film disposed in the exposure opening may be independently exposed at the will 0f the photographer.

Another object is the provision of a device of this character which is particularly designed for use in connection with modern types of folding cameras having the usual extensible bellows supporting the lens and shutter mechanism.

With these and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a rear elevation of a well known'typ'e of camera, showing the invention applied thereto, the removable' rear plate or back of the camera being detached,

Fig. 2 represents a perspective view of one of the doors of the .attachment removed from the camera, and

Fig. 3 represents a transverse sectional view through the door.

Referring t0 the drawing in detail, wherein similar reference'numerals designate corresponding parts throughout the several views, the numeral 5 indicates a well known type of camera body having the usual film spool-receiving chambers 6 at the opposite ends thereof separated by a substantially rectangular frame 7, providing the exposure opening and to which the extensible bellows 8 is' attached. The usual lens support 9 and lens l() are secured in the front end of the bellows 8 and the spool in the ilm-receiying chamber 6 is actuated by the usual manually operable key 11. v

In applying the improved attachment to the camera a pair of parallel shafts 12 is rotatably mounted in the frame 7, one shaft being located adjacent each end 0f the latter. Each shaft 12 supports a door, designated generally by the numeral 13, which 1s of approximately one-half of the size of the exposure opening in the frame and may be swung to either open or closed position, 'as desired. Each door 13 comprises a body plate 14, preferably constructed of spring metal and tapered from end to end. The relatively large end of the body plate 14 is rolled, as at 15, about the shaft 12, andis riveted or otherwise rigidly secured to the shaft for rotation therewith. i The' plate 14 is of such size as to permit it to be moved to open position and lie snugly against one of the sides of the bellows 8, as illustrated at the left of Fig. 1, and a covering 16 of cloth, paper, or other suitable flexible material is folded over the body plate 14 and constitutes the shield or screen for obscuring one-half of the ilm or plate disposed lin the exposure opening in the camera. Ow-

ing to the inherent flexibility of the covering 16, l,the door 13 as an entirety, may be swung to open position, and the portions of the cover 16, which project beyond the converging edges of the body plate 14 are folded against the top and bottom 0f the bellows 8, as clearly shown at the left of Fig. 1.

Each of the shafts 12 Ais extended, at one end, through the top wall of the camera body 5 and is directed angularly to provide a crank or handle 17, by which the shutters may be conveniently adjusted.

What I claim is:

A camera including a frame having. a second frame carrying a bellows, a pair of vertical shafts journaled inthe frames and 'extending exteriorly of the camera and bent to form handles, a tapered metallic body plate secured to each 0f said shafts and of such size that it will snugly it a side of the bellows when in open position, each of said plates having flexible opaque material secured thereto and projecting beyond its upper and lower edges and beyond its end remote from its shaft to engage said second frame when said plate is in closed position and adapted to bend to conform to the top and bottom walls of the bellows when said plate is in an open position.

In testimony whereof I aiX my signature in presence of two Witnesses.

ALFRED ANDREWS. Witnesses:

L. W. JONES, W. F. SMITH.
