SPECIFICATION forming part of Letters Patent No. 553,494, dated January 21, 1896.

i Application filed March 18,1895. Serial No. 542,169. (No model.)

70 @ZZ whom, t may concern.-

Be it known that I, CARRIE EDITH illo- MURRY, a citizen ot the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Cameras; and l 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.

My invention relates to an improvement in cameras; and it consists in the construction and arrangement of parts hereinafter described, and deiinitely pointed out in the claims.

The aim and purpose of the invention is the provision of an improved instrument whereby enlarged or reduced reproductions of images or objects may be made, and in addition thereto to so construct the device that the same may be used for advertising purposes and for projecting images or objects onto a canvas.

A further object is the production of an instrument of the nature referred to which will embody structural simplicity,rendering its production inexpensive and one which may be easily operated.

These objects are attained by the construction illustrated in the accompanying drawings, wherein like letters of reference designate corresponding parts in the several views, and in which- Figure 1 is a side view of the camera. Fig. 2 is a vertical section through Fig. 1 on the line x 0o. Fig. 3 is a rear view, and-Fig. A is a slightly-modiiied form. Fig. 5 is a detail view of the table-adjusting means.

1n the drawings, A designates a rectangular box having a top with a slightly-inclined part B and ila-t open part Bl The rear face of the box is formed in sections a, a and c2, the former being at the base, while the sections a' a2 are hinged respectively to the lower section and together and are held in place by suitable hooks a3. In the section a' is formed an opening in which a lens C is placed. On top of the lat top portion B is a swinging rectangular case D, hinged at its lower rear corner, as at CZ, to the box at a point slightly back from the edge. This case D is closed and has a lens Dl in its base and carries a telescopic or extensible bellows-tube E on its front face registering with an aperture which is located diametrically opposite an inclined mirror C', secured in the box over the lens D. The telescopic holder has a lens D2 in its end.

Centrally within the box A is a verticallyadjustable table formed preferably of a mirror F, which is mounted on brackets f, carrying racks j", which mesh with pinions F mounted in the sides of the box. The pinions are turned by suitable knobs f2 extended to the outside of the box. The mirror or table is tilted by being pivotally or otherwise mounted in the brackets,and when the desired angle is reached the same is locked by setscrews]L13 or other suitable means.

G designates a slideway in line with a lens g located in the front of the box. In this slideway suitable lantern slides may be placed when th'e instrument is to be used as a magic lantern.

In operation the case D is turned up, as shown in Fig. 1, its forward edge resting on a suitable flange d2. The case thus forms a closure for the flat top or end. The telescopic lens-carrier is then adjusted, and the picture or object is thrown onto the mirror in the casing D and from there through the lens D onto the table, on which a suitable drawing-board may be placed. The lenses are arranged to reduce the size of the object projected therethrough. Then it is desired to enlarge a picture or object, a lamp, as at L, is placed back of the lens C, or the back section may be removed so that the rays of light will strike the picture or object lying on the table and being magnified by the lens D' will be deilected by the mirror C' through the lens D2 onto the canvas.

The use of the horizontal lens D' is of the utmost importance, as it serves to strengthen the outline and reflected image, so that when the same is projected through the outer lens itwill be strongly delineated in line and color onto the canvas. By adjusting the table the object may be properly focused relative to the lens, and this whether the instrument is used in its obverse or reverse order.

Vhen the light is required to be exceptionally strong the lens C is employed. lVhen it is desired to make a reduced reproduction of an IOD object or picture the mirror or table is inclined so as to reflect the image through the lens C onto a can vas arranged opposite thereto.

In packing the instrument for transportation the case D is turned on its hinges until it is carried into the box, the case being of a length less than the box, the rear side of the case serving to close the open top, and as the back is adjusted the upper section a2 will hold the case in place.

\Vhen it is desired to employ the instrument as a magic lantern, the lamp, which is properly shaded, is placed below the opening in the top. The case D is swung back and the mirror or table is tilted out of position. Slides are then placed lin the slideway, and the picture on the slide is thrown onto the canvas in the usual manner.

Then it is desired to employ the device for advertising purposes, a detachable bracket M is secured to the forward edge of the box, and an inclined mirror II is then secured at its outeil end in front of the lens D2. The image is thereby reflected onto the i'loor or walk.

The attractiveness ol' the instrument as an advertising means may be further amplilied by having the mirror in the case D ol' concaved or convexed form and oblong.

I am aware that many minor changes can be made and substituted for the parts herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A camera, of the kind described consisting of a box havin g a removable back, a movable case on the upper end and 'rear of the box, a lens at the base of the case, an inclined mirror in the case, an independent horizontally adj ustable hold er on the Afront of the case, a lens in the holder, and a tiltable table below the case, substantially as described.

In a camera, the combination with a box having a removable back, a lens in the back, and a table in the box, ci' a case hinged on the top of the box, a lens at the base ol' the case, an inclined mirror in the case, and a telescopic holder on the case having a lens therein, substantially as described.

3. In a camera, the combination with a box, of a case on the box, a lens at the base of the case, a table in the box below the lens, a mirror in the case, a telescopic holder on the ease having a lens therein, and a mirror arranged in front of the holder, substantially as described.

el. A camera of the kind described, consisting of a box, a ease on the box having a horizontal lens at its base and an inclined mirror, a removable back for the box, a lens in the back, and a vertically adjustable tiltable table below the lens in the ease, substantially as described.

5. In a camera, the combination with a box having an open top, oi' a casing ol' a length less than the width of the box, a hinged connection between the rear of the easing and box, a lens at the base of the casing, an inclined mirror in the casing, an adjustable support below the lens, and a removable back for closing the entire rear ol` the box, substantially as described.

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