application leri April 22, 1399. Serial No. 714,071. (No model.)

To all whom it nttty 0071/007172.:

Beit known that l, HANNIBAL GOODWIN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Cameras; 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, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The object of this invention is to enable a series of individual films, each of a size to receive a single light impression from the lens, to be stripped from a paper support one af ter another after having received the impression and be deposited in a dark storage-chamber, each lm of the series then being separate from the others, so that when the camera is opened in the dark closet and the films removed no cutting or severing operations will be required preliminary to developing the pictures, fixing, rbc.

Further objects are to secure greater compactness of construction in the camera, to reduce the cost of the camera, obtain increased convenience and greater facility in loading, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved camera and in the arrangements and combinationsof parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim. l

Referring to the accompanying drawings, in which like characters of reference indicate corresponding parts in each of the several is a plan, and Fig. 7 a longitudinal section, and Fig. 9 a perspective View, showing portions of the series of films employed in the camera; and Fig. 8 is a greatly-enlarged section to show certain cement.

In said drawings, a indicates the camerabox, having the usual lens l) in any suitable arrangement, an open diaphragm c, disposed at or near the focal plane of said lens, and a partition d, arranged within the camera at right angles to said open diaphragm to form a dark storage-chamber e to receive the lightimpressed films and store the same away from actinic light-rays until it is convenient to remove said iilms. A passage f leads into said dark chamber from a point behind the open diaphragm, at the upper edge thereof, the said passage being formed by an angle-piece g, the upper vertical extension g of which closes thc rear end of the dark chamber and the horizontal extension g2 forms the upper wall of the passage. The sides and bottom of the camera-box and the horizontal extension of the an gle-piece g project a little-a quarter of an inch, more or less-back of the open diaphragm and at their rear edges receive or form bearings for the separable film-holder h, the joint Where the parts contact being broken or made impervious to light by a band or lapping-piece t' or in any other suitable manner. Said film-holder h comprises a boxlike part adapted to be held to the camerabox by catchesj or in any other suitable manner, the front plate or platen It' lying a little back from the open diaphragm c, parallel therewith, a space or passage o being formed between of sufficient width to permit a free passage for the film and its support between said platen and the open diaphragm, in which passage o the film stands in the act of exposure. The lower end or edge of the platen terminates a little short of the bottom of the film-holder to form an open passage l for the film as it passes out from the roll or spool m, the lower edge of the platen 7c being preferably rounded, as at n, to prevent injury to the film.

Back of the platen 7n the film-holder is chambered, the Ichamberp containing the roll or spool m and a swinging spool-holder q furnishing pivotal bearings for the spool. Said spool-holder comprises a pair of springs r fr, held together by a connection s near their ICO pivotal ends, the said pivotal ends t being perforated to receive the pivotal shaft n, disposed near the top of the chambery). The lower free ends of the springs provide pivotal bearings for the spool m and normally press against the ends of said spool to produce sufficient friction to prevent a premature unwinding of the spoel. Upon the removal of the film-helder 7L from the camera-box and Withdrawal of the platen 7s from the f ront of 'said film-holder the spool-holder at the free ends of the springs can be swung outside of the chamber p, where the said free ends can be freely manipulated to insert or remove the spool. When loaded, the spool-helder q is simply pushed back into the chambery), when said holder q is caught automatically and held in fixed operative position by catches i', which engage the outer sides of the springs and both hold said springs from pivotal movement and fi'oin spreading, although this latter movement may be also prevented by the side walls of the film-holder, as indicated in Fig. 3.

At the upper end of the film-passage o is stationed a stripping-blade tu, adapted to enter behind the free ends of the lm as the latter are drawn ont from the passage o after exposure and detach the said films from the support to which they are secured, as hereinafter described. The said stripping-blade is preferably fastened beneath the angle-piece g, projecting down therefrom at an incline away from the passage f, as shown in Fig. 2, the lower edge lying near to the outer face of the platen and preferably extending slightly into a recess tf, formed near the upper edge of said platen, so that the paper support to which the detachable films are secured will be fiexed away from the passage j' preliminary to a contact with the edge of said blade. Above said blade an out-passage slot w is formed of a width sufficient to receive the paper support. Said slot w" is preferably formed in the band or lapping-piece t, which is preferably of metal. At the upper end of the film-holder, preferably upon the band t, neartlie opposite sides of said holder, are secured ears or bearings 3 3, in which is arranged a drum 4, having at one end a ratchet-and-pawl mechanism 5 of any suitable hind to prevent back movement and at the opposite end a finger-piece G, by means of which latter the drum 4t may be turned on its axis. Means are provided, such as the hooks 7, for fastening the paper support to the drum, so that when said drum is turned the said paper support will wind on said drum and effect an unwinding of said support and the films thereon from the spool m. The tension produced by the friction on the spool m keeps the support and films thereon smooth in their passage in the focal plane of the camera.

Atthe top of the camera-box, or at least at one side of the dark chamber c thereof, is arranged a removable cover c, which permits an easy removal of any one ofthe exposed and stripped films prior to a complete unwinding of the pellicle containing or holding unexposed filins. Thus the operator is not compelled to await a complete unwinding of the spool m, but can secure a specially-desired exposed film as soon as he can gain access to a dark closet.

To adapt the device more perfectly for daylight loading, l have employed in connection with the dark chamber a friction or drawing wheel 8, adapted to positively draw the lightimpressed or exposed films into the dark chamber c, and a shutter ll. for closing the dark chamber perfectly against the entrance of light in the event of the removal of the film-holder 7L from the box (t. The drawingwheel 8 is shown in Figs. land 2 and is preferably provided with small teeth il or other suitable means for producing sufficient friction or holding` power of the wheel upon the films as to draw the films positively into the storage portion of the chamber e. These teeth 9 are preferably disposed at the opposite ends of the drawing drum or roll S, and in connection with said teeth I prefer to employ a light spring or springs l0, suitably attached to the adjacent Walls of the dark chamber and lightly bearing upon said teeth.

At the inner endof the passagefl employ the shutter ll, which closes said passage automatically, preferably by the aid of a light spring l2.

Before the film is detached from its` support, as hereinafter described, the forward or upperend of said film is caused to press against the outer side ofthe shutterf, and because of the freedom of movement of the shutter the latter is pressed upon and the film is directed against the roll S, the said roll-being free to turn therewith until the upward push produced by the attached support ceases. After the detaching of the film from its support by the stripping-plate the films, which have been thrust partly into the dark chamber and lie vithin the passage j and on the roller S, are forwarded into the dark chamber by the said wheel 8 and spring 10. This may be done preliminary to the removal of the film-holder S from the camera-box to reload it oi for other purposes. l turn the said roll 8 by hand-power from the outside of the box a, a suitable finger-piece 13, Fig. l, being employed for that purpose, when the said films will be rolled forward from the passage/"and dropped into the dark chamber. The shutter ll then closes the passage f automatically, preventing the entrance of light and permitting the detachment of the filmholder without danger of fogging the lightimpressed films within the dark chamber.

The series of films employed is shown in part in Figs. G, 7, S, and 9, where 2O indicates a long strip of opaque paper serving as a support for the series of separable films, and 2l 2l 2l indicate the films attached to one side of the support by cementitious or adhesive matter IOO IIO

IZO

22, Fig. S, of any suitable kind, the said matter being so applied as to permit an easy detachment of the film by the strippingblade. This may be accomplished by applying the cement 22 to only parts of the film, and the upper or forward edge of the film is not caused to adhere to the backing or support, and thus when said support is turned in its course just prior to its passing over the stripping-blade the partly-detached film will stand out from the support or backing to permit the entrance of the blade between, as will be understood.

Each film of the series is identified both on the film itself and on the bakhxg or support, the serial identifying-marks on the paper coming into sight as tHe-latter is drawn out of the camera, so that the operator may easily know the number of the film at the platen, and thus make a record by number of the View being taken and the identifying-mark on the film enabling the operator to select while in the 'dark closet any particular View he may wish to withdraw from the collection stored in the dark storage-chamber. The ends of the support 2O extend considerably beyond the ends of the series of films and serve to inclose the films on the spool and protect the same from light While on the market.
