PHOTOGRAPHICMPLATE CARRYING AND TRNSFERRENG CASE.

SPECIFICATION forming part of Letters Patent No. 607,052, dated July 12, 1898.

Application filed September 2, 189 7. Serial No. 650,373. (No model.)

To all whom it may concern:

Be it known that I, JAMES C. KIMsnY, a citiren of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in PhotographicPlate Carrying and Transferring Cases; 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 is an improvement in carrying-cases for photographic dry-plates, the object of the same being to provide an apparatus which will carry a large number of plates approximately one upon the other and permit of their being transferred to an ordinary plate-holder without risk of exposure, provision being made for unloading the holder after exposure of the plates.

In the art of photography numerous attempts have been made, with more or less success, to provide a magazine-camera using the dry-plates and including mechanism for bringing them into place, successively, for exposure, such contrivances making the proper adjustment of the camera very difiicult of accomplishment and not giving the satisfaction had by the ordinary removable plate holder. Appreciating the many advantages of the plate-holder and also its disadvantage of limited capacity in carrying plates, I have devised a case or box in which a number of plates can be closely packed and dropped one at a time into the plate-holder, which is slipped into place for the purpose, said plate-holder being reversed in iillin g the same, the particular construction and arrangement of the parts or instrumentalities entirely preventing the slightest exposure of a plate during its transfer from the storagecompartment to the plate-holder or during the unloading of the latter.

The invention anticipates an apparatus by which but a single plate-holder is needed in taking a large number of exposures, the loading and unloading of said plate-holder not requiring the services of a dark room or even so much as a cover for the box, the light being at all times entirely excluded from the compartment, which contains both the unexposed and exposed plates.

The following specification will give a detail description of the parts constituting the invention, and what I consider to be novel in the art will 'be more particularly set forth in the appended claims.

In the accompanying drawings, which form a part of this specification, Figure l is a front elevation of a carrying and transferring case for photographic dry-plates constructed in accordance With my invention. Fig. 2 is a transverse sectional view of Fig. l. Fig. 3 is a similar view on the line 3 3 of Fig. 2. Eig. 4 is an enlarged detail view of one, of the spring plates or supports for the photographic plates. Fig. 5 is a detail plan view of a backing for the photographic plates to slightly separate them when placed one upon the other. Eig. 6 is a view showing the backing applied. Fig. 7 is a transverse sectional View through Fig. 6. Fig. S is a detail sectional view illustrating an attachment to the plate-holder for wedging the plates therein.

In carrying out my invention a rectangular box or casing A is constructed, presenting a compartment of the proper dimensions horizontally to suit the size of the photographic plates which it is designed to contain, said box being painted black interiorly and preferably covered to totally exclude light,which might otherwise enter at the joints. The upper and lower ends of this box are formed by hinged covers or lids a a', held in place by hasps b, engaging staples b', or by other suitable fastening devices. In the front of this box, at or near the upper and lower ends thereof, are transverse openings c and c', respectively', adjoining which, toward the center of the box, are slits d d', extending parallel with said openings, the slits communicating at their ends with grooves d2 in the sides and connecting with a corresponding groove d3 in the back. The slits receive metal plates or slides, the edges of which iit within the grooves, and said slides serve to exclude from the center or intermediate portion of the compartment what light may enter through the kopenings o and c'.

The interior of the box or casing A is pro- IOO vided near its lower end with shoulders e c and el, forming surfaces against which bear the photographic-plate holder, hereinafter described, said plate-holder being held tightly against the shoulders by [lat springs f j" and the front of the box rabbeted, as shown at CL2, to receive the transverse ridge usually formed on said plate holder. lt will be here noted that when the plate-holder is in place the light will be excluded thereby from the central portion of the compartment and permit the withdrawal of the slide D in dropping a photographic plate into the plate-holder, as hereinafter explained. rlhe box is also provided at its upper end with shoulders g g and g on a line with the lower edge of the upper opening c, springsff being also provided at this point to force the plate-holder against said shoulders.

ln the inner side of the front and back of the bex creasing,beginning at apoint slightly above the lower slide D, are formed tapered recesses all, in which are located spring-1n etal plates ll ll, attached to the box at their upper ends to leave their lower ends tree, said lower ends being` turned at right angles to present blades 7i., which enter between the photographic plates (designated by the letter S) and serve to support them within the box. rlhese plates are operated by rods 7L', which extend through the box and terminate in knobs h2. The blades of the plates are located above the slide D a distance slightly greater than the thickness of the photographic plates in order that when said spring-plates are moved into the recesses to permit the photographic plates to drop upon the slide and then released the blades will enter between the lower photographic plate and the one immediately above.

For the purpose of separating the photographic plates and permit the blades to enter between them each photographie plate is provided with a backing T, consisting of a sheet of paper or other material having strips t at its side edges to give additional thickness, while the corners are extended to form flaps t', those at one end of the sheet being folded and pasted to form pockets and those at the other end left free to be folded over the cerners of the plate after it has been placed in engagement with said backing, the last-mention ed ilaps having adhesive material applied to facilitate pasting the ends upon the sheet. This backing leaves the front side of the photographic plate entirely7 exposed, with the exception of the corners, which are covered by the pockets. rlhe opposite ends of the backing are eut away, as shown, so as not to interfere with the blades.

The plate-holder S is of the double-plateholder pattern of the ordinary construction, having a partition-plate and the usual slides s s, being modified in the particular to have the plates inserted from the front after the slide is withdrawn, and in order to hold the plate in place one side of the holder is provided with a wedge-shaped recess, in which is located a wedge n, having an operating-rod a extending through a longitudinal opening in the holder and bent upon itself to enter a second opening therein, presenting a looped handle. By pushing upon the rod the wedge engages one edge of the plate and holds it securely in place.

From the foregoing description, in connection with the accompanying' draw ings,the construction and operation of my improved photographic-plate carrying and transferring ease will be readily apparent, for after the unexposed plates have been placed in the compartment between the slides l) and lli', resting upon the blades ofthe spring-plates ll ll, said. sprin g-plates are manipulated to drop a photographic plate upon the slide D, and the plateholder being inserted in the lower opening e" said slide is withdrawn to permit the plate l o drop into the plate-hold er,it being understood, of course, that the upper slide oi' said plateholder is first withdrawn. The slide is then inserted into the plate-holder, and after pushing in the slide D the plate-holder is reversed and the operation repeated to lill said plateholder. ln disposing of exposed plates the plate-holder is inserted in the upper opening, the lower slide thereof withdrawn, dropping the plate upon the upper slide l), which is then withdrawn to drop the plate into the compartment above the unexposed plates, the exposed and unexposed plates being separated by a follower uf, which. is preferably oli' a thickness to be engaged by the spring-plates when resting upon the lower slide l, thus denoting when all of the unexposed plates have been removed, as in the operation of filling the plate-holder it is reversed in the upper opening in unloading the saine, care being taken to have the slide D in pla-ce when removing the plate-holder.

The apparatus described forms a simple and el'leetive arrangement for loading and unloading photographic-plate holders, and it will be particularly noted that the full capacity of the compartment between the slides is utilized, the plates being removed from below, exposed, and then placed on top, the spaces employed forinserting the plate-holder being comparatively small. By the `use of this apparatus the photographer can load and unload his plate-holder without refpiiring a dark room, and can therefore carrya quantity of plates in a more compact form and at less expense than by the usual method of carrying a number of mate-holders.

rlhe photographic plates are placed. within the case through the opening covered by the hinged top and withdrawn or removed by turning the box or case upside down. This would of course dispense with the necessity of having the bottom hinged.

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

l. A carrying and transferrin g case for pho- IOS IIO

tographic dry-plates, comprising a box enlarged interiorly at each end forming shoulders surrounding three sides of the interior, the front of the box having transverse openings at its upper and lower ends communicating with the enlarged spaces in said box, slides located adjoining the upper and lower shoulders, respectively, and forming a central storage-compartment, spring-plates secured at their upper ends within the box and having each an inturned blade located a certain distance above the lower slide, and rods extending from said plates directly through the sides of the box; the parts being constructed and arranged to receive an ordinary plate-holder passed into the enlarged spaces in the ends of the box through the openings in the front thereof, as shown and described.
