THOMAS S. VILES, OF ALBANY, NEW YORK.

MAGAZINE FOR PHOTOGRAPHIC CAMERAS.

SPECIFICATION forming part of Letters Patent No. 423,649, dated March 18, 1890. Application filed December 2l, 1888. Serial No. 294,269. (No model.)

To all whom, t may concern.-

Be it known that I, THOMAS S. VILES, a citizen of the United States, residing at Albany, in the county of Albany, State of New York, have invented certain new and useful Improvements in Magazines for Photographic Cameras, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to magazine plate-holders for photographic cameras; and it has for its objects the provision of a magazine capable of holding a number of plates and permitting the successive exposure of the same without requiring a construction which involves a part proj ccting beyond the outlines of the camera-back and a magazine which is not only adapted for the storage, delivery for exposure, and reception after exposure of sensitized plates of glass, but also of photographic iilms when mounted on paper, zylonite, celluloid, or any other thin4 base, whether iiexible or otherwise.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

, The present tendency of the art being the employment of thin iiexible bases for the sensitized fil n1 made on paper, zylonite, Celluloid, insoluble gelatine, and other substances, and the natural tendency of such bases being to curl on account of the strain lexerted by the contraction of the film in drying, some means is required to hold the plate, when made of such substances, in a perfectly-fiat position i during exposure. It has been essayed to overcome this objection by coating both surfaces of the base, intending that the contraction of the coatings on opposite surfaces shall counteract each other. This involves mechanical difiiculties and increased cost. It has also been the practice to insert such thin plates in holders or carriers of substantially book form, having a front protecting-rim provided with posterior vertical flanges and a back consisting of a slab of wood or other convenient material to fit within the lianges and retain the film between the back and the front protecting-rim. lVhilesuch form of carrier answers, practically, the purpose in view when used in connection with ordinary platediolders, it

is not well adapted to magazines by reason of the excessive thickness thereof. The t-hinnest carrier of the construction above mentioned is three thirty-seconds of an inch, equal to .09375 of an inch,while a holder constructed in accordance with my invention to carry the same film is but .0&7 of an inch in thickness, a reduction in thickness of .04675 of an inch, substantially one-half, or fifty per cent.

Referring to the drawings, Figure 1 is a partial front elevation of the magazine. Fig. 2 is a horizontal section, on an enlarged scale, of certain details of Fig. 3, the section being taken on the line 1 1 of Fig. 1 and 2 2 of Fig. 4. Fig. 3 is a horizontal section on the line 1 l of Fig. 1 and line 2 2 of Fig. 2, showing the plateholder engaged with the front of the magazine. Fig. 4t is a partial elevation of the back of the plate-holder- Fig. 5 is a horizontal section on the line 3 3 of FigAE and L1 et of Fig.6, showing the plate-holder engaged with the back of the magazine. Fig. 6 is an elevation of the back of the magazine. Fig. 7 is a horizontal section, on an enlarged scale, taken on the line 3 3 of F ig. et and a 4 of Fig. 0, of certain details of Fig. 5. Fig. 8 is a partial vertical section on the line 5 5 of Fig. 10 of the magazine, showing certain details of the slides in elevation. Fig. 9 is a partial front elevation of the plate-holder. Fig. 10 is an end elevation of the magazine, plate-holder, and part of the back of the camera. Fig. 11 is a partial section of the magazine, taken on the line 6 G of Fig. 10. Fig. 12 is a partial plan of Fig. 10. Fig. 13is a vertical section on line 7 7 of Fig. 5. Fig. 14 is a perspective of the plate-receiver. Fig. 15 is a perspective of the metal platecarrier. Fig. 1G is a perspective of the metal plate-carrier modified. Fig. 17 is a perspective of the follower. Figs. 18 and 19 are perspectives of portions of modified lilmfcarriers, and Fig. 20 is a modiiied construction of the plate-retainin g spring which may be employed with the plate-carrier.

Like letters refer to like parts in all the iigures of the drawings.

For clearness of description all surfaces in the direction of the lens are designated as the front 7 surfaces, and the opposite surfaces are designated as the back.

Referring more particularly to Fig. 3, A represents the back frame of a camera, A a

portion of the bellows, and A2 the bellowsframe, these parts being of the usual construction. B represents the plate -holder proper, and in order to adapt it to be applied to any ordinary camera it may be provided with springs B X, (see Fig. 13,) which are adapted to enter the opening in the camera-frame and bear upon the inner surface of said frame, thereby retaining the plate-holder from accidental displacement. Any other 4well-known connecting device may be employed instead of the springs BX. v

One of the objects in providing the springs B is to adapt the plate-holder B and the magazine hereinafter described to be used in connection with that class of cam eras in which the focusing-glass is removably held in position by springs which yield and permit of the interposition of an ordinary plate-holder, said springs then serving the additional function of retaining said ordinary plateholder in operative position for exposing' a plate therein.

When my plate-holder and magazine are to be used in connect-ion with cameras having a hinged focusing-screen, the plate-holder may be attached in any suitable manner to the camera-frame. In fact, my plate-holder may be permanently secured to or formed as a part of the camera-frame.

The plate-holder proper B is rabbeted for the reception of a plate-receiver C, having an exposure-openin g substantially agreeing with that of the camera. In this instance, and in order to reduce the thickness of the plateholder, one wall of the rabbet is formed by attaching a metal plate B to the front of the plate-holder and allowing' it to project inwardly. A spring C is `provided to force the plate-receiver toward the magazine. Vhile the plate B. forms what may be termed the front wall of the rabbet, another plate B2 of metal is employed to form the side Wall of the rabbet, and it extends throughout the depth of the rabbet.

B5 represents a slide for closing the back of the eXposure-opening'of the plate-holder.

B4 represents the beveled strips in which the slide B3 operates. ln this instance the plate B and the beveled strips B" are secured by. rivets passing through them and through the frame-work of the holder. The slide B5, Fig. 13, passes to a point outside of the plate B2, and is then bent forward and again laterally beneath its beveled strips Bl. At the forward angle there is formed on the slide a projection or teat B5, and the frame-work of `the holder is grooved or rabbeted adjacent to the plate B2 to form a passage-way for said projection. The strip B2 is bent at its end, as shown at B25, Fig. 4, to project across the path of the projection B5 on the slide, so as to prevent its complete withdrawal. At the side or end opposite that at which the slide is entered and withdrawn the plate-holder frame is provided with a plate B5, Fig. 3, which forms the exterior surface of that end ot' the frame.

This plate is projected beyond the rear surface of the frame, and is provided with dowels B7, adapted to engage with holes D', formed in the magazine D, thereby serving the function of retaining the magazine in contact with that end of the plate-holder.

The magazine D comprises a main framework having a continuous opening therethrough of a size suited to the plates intended to be stored therein. It is provided with slides D2 D5. The exterior surface of its slide-receiving end is formed with projecting ribs D4, and the slides are bent to embrace said ribs. A similar rib B7X is formed on the adjacent exterior of the plate-holder, and its slide B3 (see Fig. 12) has secured thereto an angle-plate B8, which fits over the rib B7". Instead of bending the plate B2 to form an obstacle for the projection B2X to come in contact with, any other well-known stop may be employed.

The slides D2 DS of the magazine are identical in construction except in the conformation of their entering edges, and they ride in beveled strips D10, Fig. 13. On the head of each of the slides D2 and D3 is mounted a locking device D5 for retaining the slide in a closed position. This device may be, as shown, duplicated, so as to lock the slide at opposite edges. to perform an additional function-namely, to lock the slide upon which it is mounted to the plate-holder slide when the two are placed adjacent to each other in the use of my invention, as hereinafter described. It is apparent that the construction adopted to perform either of these functions may be omitted, and that for performing the remaining function retained-as, for example, when used upon an ordinary plate-holder to retain the slide thereof in a closed position.

The locking device consists of a reciprocative plate D5, mounted upon the head of the slide,in this instance by means of headed pins or lugs D, Fig'. 10, passing through the slots D5, formed-- in the plate, whereby thc same may be reciprocated upon the head. then reciprocated in one direction, an end of the plate D5 is projected under an ear D5, formed on a plate, which for convenience is in this instance secured to the top and at the end of the frame of the magazine by screws DSX, Fig. 12. This plate is duplicated, as shown,when two locking devices are employed. The locking device or plate D5 is provided with a riser D5X,which has projecting therefrom a handle or finger-piece D5 and a hook or headed rivet D2. By reference to Fig. 9 it will be seen that the head of the slide B2 of this plate-holder has a hole BS to receive the head of the hook or rivet D9 and a communicating slot B8X to receive the shank of said hook or rivet. The locking end of the hole B8 or of the slot B8X in the head of the slide 4B3 is so disposed as to direction that when the endot the plate D5 is in locking contactwith the cooperating ears DS on the magazine the latter It is also further constructed l IOO IIO

may be removed from the plate-holder, and when the locking device or plate D is out of contact with the ears D8 the magazine-slide is securely locked to the slide of the plateholder. lt will be seen that this construction prevents the Withdrawal of the magazineslide D2 or D3 until it is firmly locked to the slide'B3 of the plate-holder, thus insuring the action of the two slides B2 and D2 or B2 and D3 as one. It also insures the locking of the magazine-slide before the magazine can be removed from the plate-holder. It is evident that the elements of this locking mechanism may be reversed-that is, the headed rivet or hook maybe secured to the head of the plateholder slide B3, and the engaging-slot may be in the locking-plate. It is also evident that f the exact relative disposition of these locking devices may be varied, it being only essential that they be arranged adjacent to each other.

E indicates a series of plates or plate or film carriers in the magazine D.

Within the magazine and back of the series of plate-carriers E there is a spring-follower F. This follower is shown in perspective in Fig. 17, and it consists of a sheet-metal or other plate of a size corresponding to that of the plate or film carriers, and preferably not thicker than a film-carrier. This follower is provided with springs F having the ends chamfered and secured by rivets F2, so that an entering slide will not abut against said springs.

The receiver C (see Fig. 14)A comprises a frame having an opening C', adapted to register with the opening B of the holder. The receiver is provided on its rear surface with flanges C2, the depth of which anges is substantially equal to the thickness of one film or plate carrier. The ends of the flanges are beveled, as at (32X, to co-operate with the slides, as hereinafter described. This bevel is shown in Figs. 2, 3, 5, 7, 1l, and 14.

It now remains to describe novel and important features of construction and function of the entering edges of theslides B3, D2, and D2. These are so constructed as to act in one relative arrangement to force the receiver C and its contained plate into the plate-holder, and in another relative arrangement to eject a plate or film carrier from the receiver and to project itinto l[he magazine. The construction adopted in this instance to embody this mode of operation is now to be described; but the conformation of these vedges to adapt them to perform the functions specified may be varied in detail from that shown. The latter is disclosed as one practicable manner of embodying the invention.

Referring now more particularly to Figs. 2 and 3, the conformation of the entering edges of the slides B2 and D2, relatively arranged or combined for transferring a plate from the magazine to the plate-holder,will be described. The plate-holder slide has its entering edge beveled on its outer or posterior surface at a convenient angle (say about thirty degrees,

as at B2X) continuously throughout its entire length. Those portions of the entering edge of the slide D2 adjacent to the lateral edges of said slide are formed with extensions D2X, projecting beyond the edge of the body portion of said slide and (relatively to the edge of the plate-holder slide B2) beyond the slide B3 when the two slides are combined. These extensions are thickened on their outside surfaces to a thickness equaling that of the two slides when combined. These thickened portions where their surfaces adjoin the beveled edge of the slide B3 conform thereto. From points immediately adjacent to the wedge-shaped edge of the slide B3 these thickened portions D2X of the slide D2 are beveled, as at D2XX, said beveled surface forming with said inner surface of the slide D2 a convenient angle, say about thirty degrees. When this combination of slides is thrust inward, the beveled edges D2XX of these extensions D2X on the slide D2 advance in a planeJ between the foremost plate EX of the series and the next plate of the series, (see Fig. 3,) whereby the said plate EX, which by the action of the spring-follower has already been projected into the receiver, is now, along with the receiver, forced into the plate-holder ready for exposure. The remaining portion of the entering edge of the slide D2 between the said extensions D2X is beveled from its outside to its inside surface at an angle similar to that of the other bevels. The housings BiX and DOX for the entering edges of the slides B2, D2, and D3, respectively, are beveled and recessed, as at BLXX, Fig. 4, and DlOXX, Figs. l and 6, to conform to the extensions D2X and DSX, forming a light-tight joint when the slides are closed.

Now, referring to Figs. 5 and 7, the conformation of the entering edges of the slides B3 and D3, relativelyarranged or combined for transferring a plate from the receiver to the magazine, will be described. The enter` ing edge of the plate-holder slide B3 has already been described. Those portions of the `entering edge of the slide D3 adjacent to the lateral edges of said slide are formed as extensions D3X beyond the edge of the body portion of j said slide, and when in combination the edges of said extensions are beveledin the plane of the bevel of the entering edge of the slide B2, (see Fig. 7,) whereby the entering edges of the slide B3 and of the extensions of the slide DS form,when in combination, wedges, the edges of which, when the combined slides are forced in, advance in a plane between the plate or film carrier contained in the receiver and the frame of thc receiver, so that the plate or film carrier is ejected from the receiver and forced or projected into the magazine. The remaining portion of the entering edge of the slide D3 is beveled from the outside surface of the slide to its inside surface. Thus it will be seen that l have disclosed one form of construction for magazine and j )late-holder'slides which IOO ITO

when combined in one way will serve to inject a plate from the magazine into the holder, and when combined in another way will eject a plate from the holder and transfer it into the magazine. l therefore do not limit my invention to the exact construction shown in this regard, but reserve the right to vary such construction in any manner and to any degree within the skill of persons conversant with the construction of such apparatuses.

Among the important functions performed by the receiver is that of bridging over the space occupied by the slide of the plateholder, and in case of a removable magazine the additional adjacent space occupied by the slide of the magazine. It is readily apparentthat a plate or a plate or film carrier in passing from the magazine to the plate-holder proper would naturally drop by gravity into the said space unoccupied by the said slide or slides when open. l therefore provide a plate-receiver which is to be advanced so as to bridge over said space and to receive a plate or film carrier which is to be transferred from the magazine to the plate-holder proper, or the reverse.

lt is apparent that any well-known form of spring may be provided for the follower F, and it is also evident that any other form of follower may be employed, so long as it conforms in size to that of the plate-carriers used in connection therewith.

This being the construction, the operation of my invention is as follows: The plateholder Bis (after the operation of focusing has been performed and the focusing-screen removed) connected with the back frame A of the camera in cases where the invention is applied to cameras of ordinary construction. Where the part B, designated as the plate-holder, is a part of the camera, then the magazine is removed until after focusing and removal of the focusing-screen, and then the magazine is connected with the plate-holder B proper. The cap or shutter is placed over the lens, and the slides B3 and D2 (being coupled together to act as one slide by the locking device) are withdrawn until the stop B2X is reached.v The springs F of the follower F now force the entire series of plate-carriers forward (it being understood that each platecarrier has a plate or film arranged therein) until the foremost plate-carrier of the series is projected into the plate-receiver C. (See Fig. 3.) The slides are then forced in, when the beveled extensions of the slide D2 enter between the foremost and next succeeding plate-carrier of the series and force the receiver, together with the foremost plate therein, into the holder B against the tension of the springs C. After exposure the magazine D is detached from the plate-holder B, is reversed, and again connected with the holder. In this action the rear slide D2 of the magazine is operatively connected with the slide B4 of the holder by means of fastening devices, so that both slides act as one. The

slides are now withdrawn, when the springs C force the plate-holder, together with the plate-carrier therein, against the magazine. The slides are now forced in, the beveled extensions of the slides striking between the beveled edge C3X of the top of the receiver and the rounded edge of the top of the platecarrier, which is in the receiver, and by the advancement of the slides between the two the plate-carrier is forced into the magazine. When the slides are forced completely in, the magazine is disconnected from the plateholder, reversed, and again connected, when the next plate in the series of the magazine may be by repeating the operation described exposed.
