MEANS FOR HOLDING AND CARRYING PHOTOGRAPHIC FILMS.

SPECIFICATION forming part of Letters Patent No. 462,116, dated October 2'7, 1891.

Application filed January 24, 1890. Serial No. 338,023. (No model.)

To all whom it may concern.-

Be it known that we, EDGAR E. ELLIS and AUGUST L. LEHNKERING, of Rochester, in the county of lllonroe and State of New York, have invented a new and useful Improvement in Means for Holding and Carrying Photographic Films, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

Our invention relates to photography, and more especially to the matter of holding and carrying the plates or sensitized films used in the art and the undeveloped negatives after exposures have been made.

The object of the invention is, mainly, to provide a convenient holder for carrying a large number of plates or films, and also a receiver for the exposed plates or films, with means to safely and conveniently discharge the plates or films from the holder to the receiver after being exposed.

Referring to the drawings, Figure 1 is a front view of the plate-holder, parts being broken away and sectioned, as on the dotted line 00 a; in Fig. 2; Fig. 2, a section taken on the dotted line y y in Fig. 1, parts being broken away; Fig. 3, a front sectional view sectioned on the dotted line 22 in Fig. 2, parts being shown in two positions by full and dotted lines; Fig. 4, a side view of the device, seen as indicated by arrow in Fig. 3; Fig. 5, an end view of the plate-holder and plate-receiver, the latter being transversely sectioned along the plane of the inner surface of the end wall; Fig. 6, a view of the inner surface of a side wall of the holder, parts being omitted; Fig. 7, an exterior view of the side shown in Fig. 6; Fig. 8, aview of some of the parts shown in Figs. 6 and 7, seen as indicated by arrow 09 in Fig. 6, the side being sectioned, as on the dotted line y in Fig. 6; Fig. 9, drawn to a larger scale, shows the edges of portions of the back piece for the films; Fig. 10, drawn to a small scale, shows another form of the film backs, and Fig. 11 shows a modified construction of the diseharger for the films.

Referring to the parts, A is the bodyof the plate-holder, and B the body of the receiver for the exposed plates or films, these bodies being made of any suitable material that will exclude the light, such as thin strips of wood,

compressed paper, hard rubber, the. The plate-holder is preferably a prismatic box in which to place a large nu mber (say f orty-eight) of separate plates or sensitized mounted films for the convenience of the photographer, either for indoor or outdoor work. These plates or films, made ready for exposure, are of a uniform size and placed side by side in a compact body within the holder. In the drawings we have shown sensitized films a, mounted upon opaque back pieces or backs b, the latter being made of wood, paper, hard rubber, or other suitable material. The films are detachable, but held to place upon the backs by simple clips 0, extending out from the back.

The interior of the holder is provided with parallel rigid guides (Z, two at each side, within which guides the mounted films are placed. These guides form bearings or rests for the edges of the film-backs and prevent them from shaking or moving laterally upon each other to the end that the films may not become worn or frayed in consequence of such motion in carrying them about. On account of these guides the mounted films can have no motion in the holder except a sidewise motion or a motion in a direction perpendicular to the planes of the films. The front side of the plate-holder is formed with a central discharge-opening e, sufficiently large to allow the mounted films to drop or pass out thereat sidewisethat is to say, in a direction perpendicular to theplane of the film. Movable stopsffff are provided, projecting inward from the sides of the holder, which prevent the mounted films from passing out of the holder until it is wished to discharge them into the receiver B. A spring-pressed follower g serves to continually press the films or the backs thereof gently against the stops, the latter being in a plane parallel with the front face of the holder. This follower is preferably a plate of some material about the size of one of the film-backs and connected with the back 7b of the holder by a slender spiral spring "11. This spring acts to push the mounted films in a sidewise direction within the holder against the stops.

The stops project from the edges of parallel side bars 7t 7t, Fig. 3, at the sides of the holder, these bars being joined at their ends by movable joints to pivotal bars Z Z at the ends of the holder. On account of being thus mounted the side bars may be moved in endwise directions, their motions in any given case beingin opposite directions, as indicated. Motion may be given these side bars by various means-as, for instance, by a pinion 0, Fig. 2, engaging teeth 1) 011 one of the bars, the shaft 7' of the pinion extending through -to the exterior of the holder and being provided with a handle sto move it. (See Figs. 3 and 4.) If is a plate secured to the exterior of the holder, provided with stops it 16 for the handle. By moving the handle to one stop 71/ the side bars, with the stops f, will be thrown to one positionas, for instance, the position shown in full lines in Figs. 1 and 3-and by moving the handle to the opposite stop a the side bars and stops f will be thrown to another position, indicated by dotted lines in Fig. 3. Now the edges of the film-backs b are not even or regular, but are formed with notches or indentures 7t, two at each side, in position to register with the four stops f; or, to more fully explain, the backs of half the number of films are notched in a manner to register with the stops f when in one position, and the backs of the other half of the films are notched to register with those stops when in the other position. The backs of one form or patternthat is to say, notched in one manner-are, for convenience, all marked l,and those of the other form or pattern are marked 2; or they may be marked consecutively from 1 to 48, the odd numbers being given to the backs of one form and the evennumbers given to the backs of the other form. hen the holder is loaded or filled with the mountedfilms,the sensitized surfaces are all turned in one direction toward the exposure-opening e in the holder and the differently notched or formed backs are alternated. For instance, if a back marked with an odd number is put next to the stops f a back marked with an even number next follows, followed in turn by another odd-numbered back, and so on; or the mounted films may be all laid togetherin this order in a prismatic body, as shown in Fig. 9, and thus placed within the holder against the stops. The back h of the holder is detachable, so that it with the follower may be removed for the purpose of inserting the mounted films, and it may be secured to the body of the holder by simple hooks or other usual means. lVhen the mounted films are placed in the holder caution is taken to set the stops f at a position in which they shall not register with the notches of the first or contiguous back, so that said back with its film shall not pass out of the holder through the opening 6. This relative position of the stops and the first back is clearly shown in Fig. 1, in which the stops respectively press against the back at the sides of the respective notches. Now when the first film is to be discharged from the holder through the opening 6 the stops are cured to the stem f of the pointer.

shifted by means of the handle 3 to the other position. (Shown in dotted lines in Fig. 3.) This brings them opposite the respective notches and the back is in consequence released and allowed to pass out. The stops are now in position to catch and hold the next back, as that is differently notched. An opposite shift of the discharging mechanism or discharger will allow that back to pass out, but at the same time catch the next one. Thus only one film can pass out of the holder at once, and the discharger has to be shifted for each film.

The receiverB for the exposed films or undeveloped negatives is constructed similar to the holder A for the films and about the same size, ithaving an opening 1; in its side similar to the opening 6 in the holderA. The exposed films are discharged one by one, as above stated, from the holder into the receiver, said holder and receiver being placed together side by side, as shown in Figs. 2 and 5, in such a manner that the openings e '1) shall be opposite to each other. To shut out the light from the holder and receiver when joined for the purpose of discharging an exposed film, the face of the holder may be provided with a groove'w, Figs. 1 and 2, around the openinge and the receiver with a corresponding tongue a around the opening 1) to enter the groove. The receiver is provided with internal guides 11', similar to the guides din the holder and for the same purpose.

To enable the operator to know certainly that the first film has passed from the holder into the receiver in any given case, a simple indicator is provided for the holder to move when the film passes out. The indicator shown is a simple pointer c, Fig. 7, arranged to turn upon a dial upon the outside of the holder. This pointer may be operated by means of a toothed lever d, Fig. 6, and pinion 0 within the holder, the pinion being se- The lever moves with the follower g, and at each time the latter advances a step, on account of a film being discharged from the holder, the pointer is turned to a new mark or space on the dial. The leveris formed with a tang g, extending out to meet the follower, and it may be attached to the follower to move forward and backward with it by means of a simple strap h, Fig. 8, secured to the follower, or the tang may be independent of the follower and held thereagainst by means of a slender spring 75', Fig. 6. Then the holder is filled with mounted filmssay forty-eight in numberthe follower is thereby pressed back against the action of the spring 2' to the back h of the holder. Vt hen in this position, the pointer points to O on the dial. As the follower advances toward the front of the holder from the successive discharging of the films singly, the pointer turns upon the dial, indicating the exact number of films discharged.

The opening 6 in the holder, through which IOO IIO

exposures are made, is closed by a rollin g slide or shutter Figs. 1 and 2. This rolling shutter is an opaque flexible sheet of some strong substance, as cloth, wound upon a roller Z at one end of and within the holder. Straps or bands n 71 lead from the shutter on either side of the opening e to a winding roller 0 at the opposite end of the holder. The shutter and the bands pass over carrying-rollers p and 0", which hold the shutter near the front of the plate-holder and in position to eifectually close the opening 6 and exclude the light from the sensitized films within. The roller 1' is provided with a coiled spring 1; to turn it in such a manner as to' wind the flexible shutter upon it. To draw the shutter over the opening 6 against theaction of the spring 22', we preferably employ a gear w, Figs. 2 and 3, close to the side wall of theholder, engaging the teeth of a pinion b on the roller 0'. The shaft a of the gear passes through to the outside of the holder, where it is provided with a crank or handle 3, Figs. 3 and i. A circular plate t is preferably employed on the outside of the holder for the handle 8, and stops u u for the handle are provided. By turning the handle in the direction of the associated arrow from its position shown in full lines to that shown in dotted lines-that is to say, from one stop 24 to the other-the rolling shutter will be brought to fully cover the opening 6. Turning the handle back to its first position, the opening will be uncovered, the spring-actuated roller Z automati- .cally drawing the shutter away from said opening. The stops u a, like the stops it u, for the handle .9 of the discharger, consist, in part, of depressions or holes, as shown, into which a projecting portion of the handle enters. Both handles are thus held by positive means in either one of their assumed positions. Instead of the long roller 0" for the bands, two short rollers of the width of the band may be used, one for each band.

The opening '1) of the receiver 13 may be closed with an ordinary slide (Z Fig. 2, or by a rolling shutter, as shown for the holder A, as may be desired.

The backs l) for the films are preferably formed with a thumb-notch 0 Fig. 3,so that the film may be more easily caught by the thumb and finger to draw it out from under the clips 0.

The lens is focused upon the film next the stops f in the holder, and as soon as one film is exposed and discharged into the receiver another film is pushed forward in the focus by the spring-pressed follower g.

Fig. ll shows a modification in the form and manner of operating the stops f and the discharging mechanism. Inthisconstruction the pivot-bars Z are without the holders and connected by a single side bar 7s. The stops are joined to the pivot-bars and move endwise in the act of holding or discharging a film. In this form the notches 'n in the filmbacks are differently arranged, as shown, to

be adapted to this construction of stops, but two of the latter acting at the same time to hold the back.

Fig. 10 shows a form of back in which, instead of notches a, corresponding projections 61 are provided at the edges of the back to be engaged by the stops f. Practically these operate the same as the notches, for the same motions of the stops cause them to be presented to portions of the back (to the projectionsd when in one position and when shifted to spaces at the edges of the backs. In either case the stops when shifted move from positions in front of parts of the back to positions in which they do not oppose any part of the back.

It will be understood that the guides d, instead of being secured within the holder, as shown, may be secured in corresponding positions to the back piece 71., and the pile of mounted films placed within them previous to being inserted in the body of the holder.

Ve are aware that a series of photographic plat'e-holders provided with notches, in combination with a locking and releasing device adapted to co-operate with said notches, is not broadly new with us.
