Application filed April25,1906. Serial No. 313.695.

To rtZ Z 1071 0711, it Huey concern:

Be it known that I, FRANK WHITNEY, a citizen of the United States, residing at Lake side, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Photographic-Plato Holders, of which the following is a specification.

My invention relates to improvements in photographic-plate holders, using the term plate as applying generically to sensitized photographic films, whether mounted upon glass plates or upon thin films of celluloid or like material or upon other material. While in some respects my invention relates to such embodied and. utilized in packages constituting magazine holders for photographic plates and especially adapted for use in the form of original packages as the same are put up by the manufacturers.

One-object of my invention is to provide an inexpensive, light, and reliable plateholder.

Another object of my invention is to provide such a plate-holder in which sin 'le plates maybe packed and sealed ready l or iarket and ready for use.

Another object of-my invention is to provide such a plate-holder which may not be readily refilled.

Another object or" my invention is to provide a package of such plate-holders so constructed that while the pie e contained in i b any one holder or" the package may be photographically exposed at will the entire package may be safely exposed daylight after any one or more ot the plates contained therein has been exposed thereby permitting of separate "focusing and adjusting of the camera for each exposure.

Another object of my invention is to provide a package of such plate containing holders which shall be interchangeable in a camera with a conventional plate-holder.

Another object of my invention is to provide a package of such plate-containing holders so constructed t at one package shall rovide convenient nomical means tor permanent tiling of the developed plates for ready reference.

Another object of my invention is to provide a package of such plate-containing holders of such character that each holder may be illllllaf:

holders per se, it is especially available when the exposure-aperture of the holder behind it after the slide has been withdrawn from such rear holders.

These and such other objects as may hereinafter appear are attained by my invention, certain illustrative embodiments of which are shown in'the accompanying drawings.

In one of the forms in which I have embodied my invention I provide a box orcasing adapted to be inserted in an ordinary plate-holder camera in place of the usual plate-holder. This casing may conveniently consist of a carton formed of light-excluding pasteboard having an edge open for the insertion of a plurality of plate-holders and having also an exposing-aperture in one of its sides. Each of the holders oi the pack consists of an envelop provided with an exposing-aperture and having a slide adapted to close said aperture and to be removed Without the withdrawal of the holder from the carton. I also provide a slide of comparatively still opaque material which may, if needed, be inserted in front of the pack* 'L. 6., between the pack and the side of the carton having the exposing-aperture therein. Each of the holders may be provided with means projecting beyond the edge of the pack, whereby the holder may be grasped and. withdrawn from the ack. T projecting means upon the ho der I pried-ably form as a tab and mark said tab with an identifying character. The stiff opaque slide may be similarly provided with projecting medans for grasping and withdrawing said sli e.

In the drawings, Figure 1 is a perspective view of such a carton containing a pack consisting of twelve plate or film holders and a stiff slide. In thisfigure the holder at the back of the pack is shown as partly withdrawn. Fig. 2 is an elevational edge view of the same, but showing a holder as being inserted at the front of the box. In this view the edge of the box is partly broken away to expose to view the holders within said box.

Fig. 3 is a vertical sectional view of the carton with the holders removed therefrom, the section being taken on the line 3 3 of Fig, 1 looking in the direction indicated by the arrows. Fig. dis an elevational rear view of one of the holders, on a reduced scale. Fig. 5 is a front elevational view of the same, on the same u as a light-tight slide to close I scale as Fig. 4. In this figure parts are the arrows.

broken away to expose to view the plate or film within the holder. Fig. 6 is a vertical sectional view of the same, on an enlarged scale, the section being taken on the line 6 6 of Fig. 5 looking in the direction indicated by Fig. 7 is a view similar toFig. 6, but showing one of the parts in a different position, as will be explained hereinafter; and

Big. 8 is a vertical sectional view of a modiiied form of holder.

In the several figures of the drawings like reference characters indicate the same parts throughout.

In the drawings, A is the casing, consisting of a rectangular box open along one of its edges and provided with an exposing-aperture a. As hereinabove stated, this box is adapted to be applied to a camera in place of the ordinary plateholder.

B is a plate or film holder consisting of an envelop of thin light material. This holder may be of any suitable material; but I prefer to construct it of tough light-excluding paper. Each of these envelops is formed with an exposing-aperture b and is provided with a thin and preferably flexible removable slide C, adapted to cover the exposing-aperture b. This slide 0 is preferably made of black or other light-excluding paper. Strips1d, e, f, and g of cardboard or other material are arranged inside the envelop, around the edges of the latter, and serve as abutments to maintain the plate or film in proper position relative to the exposing-aperture, as clearly shown in Fig. 5, and preferably so as to permit the slide to overlap the plate, as shown.

The strip (1 is shown as being of somewhat greater width than the strips e,f,and g and is provided with a long narrow opening or slit F. The thin slide C is provided with a flap c, which projects backwardly and outwardly through the slit F and a corresponding slit in the back of the envelop. So far as the simple purpose of excluding light is concerned, of course, the slide may extend out of the envelop constituting the plate-holder in any manner which will permit of the convenient The tortuous exit for the slide which is shown in the drawings is merely one preferred embodiment comprising additional advantages which will hereinafter be fully pointed out. When the casing A. is filled with these holders, as shown in Fig. 1, and before the plates have been exposed, these iiaps are turned downwardly, as shown in Figs. 4 and 6, and, if desired, may be sealed lightly or otherwise; but when a holder has been drawn from the pack this flap is turned up, as shown in Figs. 2 and 7 holder is reinserted at the front of the pack. The flap is thus left extending upwardly from the pack. and may be readily grasped for withdrawing the slide and making the exposure. 'iheouter edge of this flap is preferably inclined or otherwise protected, so as to before the seaseo overcome the danger of its becoming caught 'pack. The envelop B is provided with an extended tab G, which may-bear upon one or both of its sides an identifying character, such as a number or letter. H indicates a slide of comparatively stiff material adapted to be inserted into the box A. and when in position therein toward the front of said box to close the exposing-aperture a of said box and prevent the passage of light into the box through said opening. This slide is also provided with a tab which is marked for ready identification with suitable lettering. These tabs are preferably arranged in echelon, as shown in Fig. 1,so as to indicate at a glance which plates have been exposed.

In making up the pack as a package for market the slide H will prevent exposure of the plate in the outermost holder because of any accidental injury to the thin slide closing that plate.

In the preferred practice holder No. 1 will be removed from the back of the pack and inserted in front of the slide H, the flexible slide C will be removed from said holder, and the tab on said holder will appear at the forward left-hand corner of the pack and segregated from the tabs of theunexposed holders.

Referrin now particularly to Fig. 1, in which the ox or easing A is shown as containing a pack of holders and a stiff slide lettered Safety-slide,. the pack, as shown, consists of twelve envelops, each containing a film or plate and each provided with a projecting tab, these tabs being numbered consecutively from 1 to 12 and from the back to the front of the pack. Each tab bears the same number upon both of its sides, the tabs being offset, so that the numbers may be readily seen and so that the tab of the holder at the rear of the pack may be easily grasped for the purpose of withdrawing said holder. I

h is a shadow-strip, which will make a light-tight joint when the carton A is inserted in a camera in place of an ordinary plate-holder in a familiar manner and will preferably be held in the desired position. by

the forwardly-projecting lip h on the upper forward edge of the camera, which serves to provide a widened slot' for the insertion of plate-holders (see Fig. 2) in the manner hereinabovc pointed out.

When a plate or film holder embodying my invention is to be employed in an ordinary platvholdor camera, the carton A, with the holders and safety-slide in position there in, "will be inserted into the camera in front of the groundglass focusing-screen in place of the ordinary plate holder. The holder hearing the figure 1. upon. its tabthat is, the rearmost holder of the pack-will be drawn from the pack and reinserted in front ice plate may beexposed.

of the safety-slide, with the flap 0 projecting .upwardly. in Fig. 2 this holder is shown as being so inserted. When it is desired to make the exposure, the slide C will be with drawn and may bediscarded; Thereupon plate-holderNo. 2 is removed from the back of the camera and is inserted in front of plate/holder No. 1, from which the slide has con discarded, the plate therein having been exposed. Thereupon plate-holder No. ll becomes a light-tight slide fitting snugly over the exposure-aperture of plate-holder N o. 1, while at the same time plate-holder No. 2 is in position so that upon the withdrawal of the slide C from said plate-holder No. 2 that Thereupon the entire package may be removed from the camera and the camera may be focused before making the next exposure, or the package may be taken into a dark room and plateholder No. I removed and the plate therein developed. Thus, if desired, the magazine may be operated so that one plate will always be ready for instantaneous exposure by the camera, or, if desired, the safety-slide may be reinserted in the front of the camera, so as to provide a light-tight slide covering the exposure-opening in the holder holding the last plate which has been exposed. When the plate or film in the last of the holders to be used has been exposed, the safety-slide will be reinserted in front of the pack, so as to close the exposing-aperture a.

Where the holders are made in the form of paper envelope, especially where the paper is folded over at the edges of the holder, and the carton is made to snugly receive a number of holders, for which it is constructed, there will be sufficient inherent resiliency in the pack ofholders to provide all of the pressure essential to provide a light-tight joint between the last plate which has been exposed and the holder or safety-slide which has been inserted in front thereof to protect such plate; but of course, if desired, the carton may be provided with any suitable special spr ng, such as the spring 75. (Shown in Fi 3.)

i or the purpose of developing the plates or films any one of the series of holders may be drawn from the pack and the plate or film taken therefrom and developed, thus affording'the advantage of permitting the development of any one or more of the plates or films, after the same have been exposed,

- without the necessity of waiting until all of the twelve plates have been exposed.

In manufacturing the individual holders they will preferably be formed of suitable paper which may be folded over, the pl ate bein seated within the marginal strips d, e, f, an g and the flexible slide being arranged in place over the plate and so as to sufficiently overlap the marginal strips (1, c, f, and g be fore the paper constituting the exposure side light-tight joint where the slide slide.

of the holder is fastened in place. When this is done it will be found that even a thickness of paper is suflicient to form the marginal strips e, f, and g, so as to hold the film in position where a flexible slide may overlap said strips and extend well toward the edges of the holder. This arrangement, together with the inherent resiliency of the holder, will insure a light-tight'joint between the slide C and the marginal portions of the holder which surround the exposure-aperture in the holder and will at the same time permit of the use of a flexible slide which shall extend out of the holder through a tortuous passage, as shown in Figs. 6, 7, and 8, thereby insuring a emerges from the ho der and also permitting the manufacturer to put up his plates in these holders in such a manner as to protect his customer against the substitution of other plates, because while the fiexible slide may be readily withdrawn after the holder has been assembled containing a plate it is for practical purposes impossible to thereafter replace said Thus the manufacturer may stamp the package with his name and with the date of the plates, and it will be impossible to impose on' the customer either by the substitution of old plates or of plates of a different make; also, the manufacturer will be enabled to protect'his own trade by making it necessary for customers who wish to utilize such holders topurchase his plates, because it will be im ossible for the purchaser of one package 0 plates to thereafter use the package of holders for other plates after the original plates have been exposed.

For constituting a permanent file the back of the carton may be provided with a form for making suitable entries opposite numbers corresponding to the numbers on the tabs of the individual holders, and each developed plate may be reinserted in the iridividual holder, inasmuch as it is of course unnecessary to reinsert the slides after the plates have been developed, and the back of the tab on the safety-slide or any suitable part of the carton, if preferred, may be marked with any suitable index character, so that if the tab be marked with the letter A and the index in which the record of the plates is kept indicates that a given negative may be found in A g it is asimple matter to discover carton A and holder 9. In other words, the packages, when used as permanent files constitute a record analogous to acard-index file.

While I have shown the casing A as unattached to the camera and have described said casing as a box adapted to be applied to a camera or removed from the same, it is of course within the scope and spirit of my .invention to form this casin as an integral part of the camera. There isfliowever, an important advantage incident tothe use of an in-.

vto hold.

forms of individual plate-holder.

T he carton A being light-tight and the safety-slide H being adapted to completely close the exposing-aperture it against the admission of actinic light, the device as a whole may be transported and handled without danger of the plates or films being affected and may constitute an article of manufacture and sale.

It may sometimes be desired to use the carton A with a number of holders less than the full number which said carton is designed It is therefore desirable that some means be provided for thrusting the holders against the front of V purpose I provide within the casing A a simple form of spring consisting of a strip of press-board or similar material it, secured at one end to the back of the casing A and curved so as to form a semi-elliptic spring.

If desired, the flap 0 of the flexible slide C may be sealed, so as to prevent accidental removal of the slide C and consequent exposure of the film or plate to the light. Preferably the corner 0 of the flap will be secured to the back of the holder. After the holder has been drawn from the pack and before said holder is reinserted at the front of the pack this corner will be loosened, so that the flap may be turned up, as hefeinbefore described.

in Fig. S I have illustrated another manner in which the flexible slide C may be mounted in the holder B so as to be readily withdrawn, but not readily returned. To attain this end, I provide a transverse groove or depression I) in the hold er.

\Vhile, as above described, my invention is adapted to a variety of uses, it is especially useful as a magazine package of out films, which can be cheaply put up in this form for market, My invention provides apackage in which each film or plate separately in-- closed in a light tignt envelop, so that it is not subjected to any accidents of fogging, scratching, accidental exposure, deposits of dust, or other occurrences which so commonly happen to photographic plates prior to exposure, and often without detection, and it affords a ready means whereby the manu facturer and the user may both be protected as to the age, character, and make of plate, and above all it provides a magazine package the casing A. For this of this character which can be made absolutely interchangeaole with any standard make of plate-holder and by means of which the camera maybe focused on the groundglass screen separately before each exposure, so that each plate may be given individual treatment, and the entire package may be safely removed in daylight at any time so as to permit the development of any one plate in the package.
