SPECIFICATION forming art of Letters Patent No. 729,325, dated May 26, 1903.

Aprlicationfiled April 1899- Serial no. 714.070. (Nomodelfi To all whom, it may concern.-

Be it known that I, HANNIBAL GooDWI'N, a citizen of the United States, residing at Newark, in the countyof Essex and State of New Jersey, have invented certain new and useful Improvements in Cameras; and I do hereby declarethe 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 letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of photographic cameras in which provision is made for the manipulation of the sensitive films individually from the outside of said camera, the objects of the present improvements being to facilitate theoperation of loading the camera, to reduce the cost of construction, and 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 photographic camera and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings,

peculiar construction adapted to be inserted in the camera-box. Fig. t is a section of the same on line to, and Fig. 5 is a section on line 00 Fig. 6 is a plan of a portion of the holder indetail, and Fig. 7 is a perspective view of one of a series or collection of out films adapted to be arranged in said holder.

In said drawings, a indicates a suitable camera-box, having the usual aperture a at the front, through which the light enters in its passage to the lens, and a partition a to which may be attached the lens-box b, or said box or the lens therein may be arranged in any other manner in connection with the attachments commonly employed in photographic cameras, such as the shutters and suitably formed at the edges to make joints with the body of the box impermeable to light.

The film-holder is formed in chambered sections or parts 0' c hinged together at d, so that the sections may be turned on the hinge-pins from the relation of alinement shown in Figs. 3 and 4, at which they may be laid out upon a table, and thus easily manipulated in loading, to the right-angularrelation shown in Fig. 2, in which latter relation they are prepared for picture-taking within the camera.

The part or section 0, adapted to stand vertically in the slideways a of the cameraboX, comprises a body-plate c bent at its opposite sides at right angles to its own body, as at c o in Fig. 5, and again bent outwardly parallel with said body to form flanges 0 0 a pressure-plate 0 arranged between the sides 0 c, and a sliding open diaphragm 0 having returned edges '0 adapted to receive the flanges 0 0 the said flanges formingslide ways for said open diaphragm and the returned side parts 0 of the open diaphragm serving as slide-tongues to enter the slideways a of the camera-box. The slide-tongues may be applied to the camera-box and the film-holder be correspondingly modified as a reversal of construction. The open diaphragm may be constructed to operate other than to slide upon the body of'the section.

The pressu re-plate c at its back is provided with bowed springs c c by means of which the said pressure plate is forced forward against the back of the series or collection of films and the latter are pressed forward ICO against the rear side of the open diaphragm 0 The back of the body-plate c is provided with openings 0 o through which the springs may project, as indicated in Figs. 2 and 4, to bear against the back board a of the box a when pressing the plate 0 and the films in front thereof forward against the open diaphragm 0 forming a part of the section 0.

The section 0 hinged to the section 0', comprises a box-like receptacle 0 open at the top and at opposite ends. By means of the pivotal connection of the two sections said sections may change in their angular relation to one another, and this not only facilitates taking the holder out of the camera and replacing it, as hereinafter described, but also enables the two sections to be brought into the same plane for the insertion of a fresh package or collection of films. The open top permits the arrangement of the films in place when loading and is provided with a cover 0, closing said open top to form a dark chamber within. The said cover is provided with suitable catches 0, adapted to engage cooperating catch projections c at the opposite sides of the receptacle, whereby said cover is held with sufficient securityin place. t its forward end said cover 0 is provided with a partition or plate 0 adapted to reduce the depth of the dark chamberand press the collection of cut films together, and thus prevent an entrance of light through the forward end opening of the holder-section The contracted mouth of the dark. chamber of said holder-section c is intended to accommodate a given quantity or number of sheets of the supports or the paper portions of the film, permitting an outpassage thereof, but preventing the outpassage of the double portions of the films Where the flexible celluloid film is attached to the face of the supportingpaper. In other words, the contracted passage 0 is formed to receive a definite number of the extensions of the supporting portions of the films only, and thus prevent the outpassage of the applied sensitive films when the latter are drawn into the dark chamber of the section 0 as hereinafter described. Said forward end of the cover is also provided with a stop flange or projection 0 to press against the inner side of the box and prevent possible free longitudinal play and close the interior of the camera against an entrance of light. A lip c or extension of the partition 0 preferably extends into the front opening at or near the bottom of the box to hold the ,part or section 0 of the film-holder down against the bottom board.

The open hinged end of the part c is of the same width interiorly and coincides with the open lower end of the part or section 0, so that the films may pass freely from the said part or section 0 into the part or section 0 when the film-holder is arranged in its angular form or relation within the camera-box, as shown in Fig. 2.

The lower edge of the open diaphragm c is preferably curved outward, as shown in Fig. 2, providing a convex bearing over which the films may be bent without injury to the sensitive portions in the act of drawing the same into the dark chamber 0 within the section or part c of the film-holder.

At or near the angle or hinge joint between the parts or sections 0 and c of said holder is arranged a stop pin or pins f. This or these are preferably rigidly mounted upon the body portion 0 of the part or section 0 of the filmholder, terminating at their projecting ends a little short of the open diaphragm 0 a sufficient space being form ed between to receive the springgand permit the passage between the spring and stop pin or pins of a single celluloidal film with its papersupport. At their upper ends said springs g are suitably attached to the rear side of the open diaphragm c and at their lower free ends said springs are adapted to press normally against the projecting ends of the stop-pinsfto prevent premature withdrawal of the film. The said stop-pins fare arranged at or approximately at right angles to the planes of the portions of the films which stand erect in the part or section 0 of the camera, and thus said erect portions bear upon said pins when stress is brought upon the rear films due to the downdrawing of the front film of the series into the dark chamber after the sensitive portion thereof has been photographically light-impressed.

In connection with this specification of the purpose of said stop-pins it is important to mention that by the bending of the package of films to a comparatively sharp angle at the junction of the two sections 0 and 0 each front or foremost film of the series can be withdrawn from section 0 without withdrawing or disturbing the next film or series of films immediatelyinits rear, and thus on account of the aforesaid angular formation of the package the remaining package can be maintained in position without the aid of stop-pins; but I prefer to employ the said stop-pins, as itmore positively insures a withdrawal of but one film at a time.

The spring or springs g is limited in its movement away from the extremity of the stop-pin by the open diaphragm.

In Fig. 3 the employment of the two independent springs g is indicated, and in Fig. 6

a single piece comprises the spring, which spring in this case resembles a metallic frame.

The parts or sections 0 c of the film-holder are of substantially uniform width interiorly, and thus the portion 7a of the film 7.0, Fig. 7, forming a backing for the celluloidal portion k having the sensitive coating, when drawn into the dark chamber of the part 0 will 6X- tend from side to side of the chamber within the part 0 thus reducing the liability of fogging due to the formation of open or unfilled crevices in the dark chamber through which the light might pass.

In the construction of the cut film 75 I employ an opaque support comprising a sheet of paper a separate and independent sheet for each celluloidal film L having the photographically sensitive coating. This sheet 7t 70 is of a length sufficient to extend from the upper end of the film-holder downward and through the section or portion a thereof and thence out from the film-holder and camera to a point where it can be con- I veniently grasped by the hand of the operl ator, as shown in Fig. 2. The portion In of the support beneath or behind the sensitive film k I haveltermed the backing. The part 10 extending from the backing I may term the handle extension. Near one end ofeach of the said sheets 75 713 is fastened by cement or other suit-able means the said sensitive film k At or near the lower ends of the films 70 the same are perforated, as at k to receive the stop pin or pins f, the perforations k extending through both the films and the papersupports or backing.

Forward from the combined film 70 and paper backing 7c in the handle extension k is formed a hole or a series of holes 75 or other indicating marks adapted to serve as an indicator or indicators in the act of withdrawing the film 7c, the said indicating marks or holes being so related to the paper handle extension k as that when said marks appear to view at the outside of the camera in the act of withdrawing the film the operator is made aware of the fact that the sensitive portion 70 is properly within the dark chamber protected from light and that further withdrawing is unnecessary.

The extensions 7r forward from the sensitive celluloidal portions 76 may be also marked numerically or otherwise by printing, perforations, or otherwise to indicate the number of each individual film in the series.

Outside the camera-box the front board is provided with a shutter m, suitably arranged in slideways 71., adapted to press the finger extensions of the series together to prevent the possible entrance of light to fog the films and adapted to act as a blade for severing each film when sufficiently withdrawn after each exposure has been made.

In operating the device, the holder being properly loaded by first removing the covers from the parts 0 0 while the same is detached from the camera, then arranging the films 7c in place therein, so that their handle extensions at the extremities project from the holder, as shown in Fig. 2, and the sensitive portions 7.3 will face toward the opening of the diaphragm, and finally applying the said covers, Ifirst insert the part 0 within the camerabox and then the part c, the latter being arranged in the slideways a and pushed downward into proper vertical position. The sections are formed so that the part c at its forward end will enter the opening (L as the part c is pressed downward. The cover a is then applied to the box and the camera is ready for service. The sensitive film at the front of the series having been exposed to light through the lens, the uppermost finger extension projecting out from the camera is drawn upon and the backing thereof is drawn away from the next film of the series at the bend in the series and is drawn from the stop-pins, so that it is free to be drawn downward. The sensitive celluloidal portion and its backing are finally drawn into the dark chamber, when the marks or perforations k in or on the extension will appear to view and the drawing will be discontinued. The portion of the film thus withdrawn from the camera-box is torn or cut off by pressing it against the aforesaid shutter-blade. Inasmuch as a hundred films, more orless, may be loaded within the holder, the need for daylight filling or loading is vir-. tually avoided.

While I have described the invention, in many instances using positive terms, I am aware that various changes and modifications may be made other than have been referred to in the construction and arrangements of parts without departing from the spirit or scope of the invention, and I do not wish to be understood as limiting myself by the said positive descriptive terms employed excepting as the state of the art may require.
