thereto and to a film splicing device, so that the film may be readily passed through the viewing is device and then, whenever desired, shifted to the splicing device and the undesired-parts removed and the film spliced. The frame of the apparatus is so constructed and arranged that it may be folded to constitute a carrying case with,

the parts above enumerated, and all other necessary adjuncts, on the interior. I thus furnish the amateur with a complete and compact apparatus which may be readily carried by him on a trip, and enables him to edit the films at any convenient time and place, and, when not bein used, takes small storage space.

The invention as illustrated in the drawings hereof is hereinafter more fully described, and

the essential novel characteristics are set out in the claims.

In the drawings, Fig. l is a perspective of my apparatus partly. unfolded; Fig. 2 is a pe p ctive of the apparatus completely closed; Fig. 3 is a planet the apparatus completely unfolded; Fig. 4 is a sectional elevation, as indicated by the line 4-4 on Fig. 3.

It is convenient to describe first the frame of the apparatus which, when folded, constitutes the carrying case for the various parts used, in 40 the editing operation. As shown in Figs. 1 and 3,

I have provided a case made up of six panels,

designated respectivel A,- B, C, D, E and F, suit ably hinged together so that they may be spread out fiat to lie on a table or folded to make an enclosing prism. More particularly, the panel B constitutes the base of the apparatus, or case; panels Eand F hinged respectively to the opposite ends of the panel B constitute the ends of thefolding case; panels A and C hinged to the 50 front and back edges of the panel B constitute the front and back of the folding, case; and panel D, hinged to the panel C, the top of the case.

The panels are preferably of sheet metal. The various hinges designated respectively e, e, a, c as and d may be of the piano-hinge type illustrated,

formed by overlapping ears on the meeting panels, embracing a wire pintle indicated by g in Fig. 1, or other form of hinges may be employed. The panels could-be of fibre, wood or other material, and as such material might be of consid- 5 erable thickness, the panels would be sufficiently spaced at the meeting-edges to permit the folding thereof.

As shown in the drawings, the panels are made of sheet metal. The panels B, E, and F are fiat 1 plates, except for the curled hinged ears. The panels A and C are flat plates provided with the hinged ears, and also flanged at their ends as at a--l and c--l, so that in folding they may overlap the end panels E and F. Likewise, the panel D which forms the top is preferably provided with flanges dl at its ends, and d--2 at its free edge, so that these flanges may overlap both the front panel and the ends when the case is folded as shown in Fig. 2. .The front and back plates go A and C may be provided with small angle clips 0-2 and c! respectively, which, when the case is folded, engage the inner faces of the end panels E and F, and limit their inward movement.

The top panel D may be provided with a suitable handle or carrying strap indicated at H, in Fig. 2, and may also have a hasp J with a hook to cooperate with a staple K on the front panel.

The various instrumentalities used in editing the film are carried on the inner faces of the so different panels in the proper position for use when the case is folded out fiat, as shown in Fig. 3, and in a position where they do not impinge on each other when the apparatus is folded. Thus, the panel B carries the viewing device III, which is preferably secured in position by a flange ll clamped to the base plate B. The panel E carries a winding device 20 which carries and operates one of the reels, as for instance, the supply reel 2|. The panel F carries the winding device 30, which carries a reel 3|, which may be the receiving reel. a

In use, the film 5 is drawnfrom the supply reel, threaded through theviewing device, and thence passes to the receiving reel. Illumination 5 is supplied to the viewing device through an electric cord 40, which leads to a bus-connector 4i secured to the panel C from which leads anv electric cord 42, terminating at plug 43, adapted to be inserted in the usual base receptacle. conductor 42 is of considerable length and may be wound up about a cleat 45 secured to the panel C.

It will be seen that when the apparatus is folded out, as shown in Fig. 3, and the film threaded from the reel 2| to the viewer. I0 and u Cir thence to the reel Ii, the simple manual operation of the crank 32 winds the film along while it is being viewed at the inspection window I2 of the viewer. When the film is completely wound on the receiving reel 3|, the free end may be passed to the reel 2| independently of the viewer and rewound on the latter reel by the rotation of the crank 22.

One of the operations of editing film is to remove undesirable sections, then cement together the desirable portions of the retained film. To enable such cutting out of sections to be efilcient- 1 performed, I mount on the panel A an approved form of splicing device comprising two adjacent clamping members 50 and BI, which are hinged at their rear edges toa suitable base. Either member provides means to clamp the film while the other may be used to cut it; that is to say, the edge of either raised clamp coacting with the other clamp when lying down on the film provides means for shearing off the film as the raised clamp is lowered into place and moved sufficiently beyond the stationary clamp to shear of! the film. Each of the plates 50 and BI is acted on by springs (not shown) to hold them normally in the proper position, but allow them to remain raised or to be moved to effect the shearing as desired. I have not gone into detail in regard to this apparatus, as it is a well-known device 1 on the market.

In editing film, when the operator observes at the window ii a section of the film that he desires to either discard or shift, the film is drawn through the viewer sufficiently to reach to the splicing device after having been severed where desired. iiiuch splicing device is mounted on one of the panels convenient position to engage a loose reach of film between the viewer i0 and winder. it. Thus 1' have shown the splicer 50, ii on the pane" .i near the rear edge thereof, and I have 3 "totally mounted the standard of the winder tile pane? P so that the reel it may be e a. vertical plane leading directly to the co such forward location while splicing, and turned directly toward reel ii for rewinding on reel ii. The operation of splicing film in standard splicing devices is well understood.

To enable the splicing operation to be carried out with the greatest efilciency, I provide a lamp it carried by the panel A and located in front of the splicing device and shielded by a reflector Si in front of the lamp. This lamp may be supplied by an electric cord l2, leading to the bus-connector ll and in engagement with the conductors of the extension cord 42.

The panel A, as shown, is provided with a pair of leaf spring clamps I0, which may removably retain a box of film cleaning materials, II. On panel D, spring clamp II holds a small bottle of oil 14, and spring clamp II holds a small pair of scissors H.

In Fig. 3 I have shown the two reels 2| and II on the spindles of the respective winders 2| and 30. In operation, the supply reel 2| comes from the motion picture camera. The receiving reel may be stored when not in use in a cylindrical container '0, mounted on the panel A and held in place by a removable strap ll.

When the apparatus is to be folded, the receiving reel is placed in the container 00, and hence there is no reel on either winder II or il. -Now, when the apparatus is folded, the two winders and fold over into the space above the viewer. as shown in Fig. 1. Then the front and back panels are tipped up into vertical position, where they move the parts they carry into the space above the viewer. Then the top may be brought down and secured by its hasp.

It will be seen that I'have provided a very compact case, carrying all of the apparatus necessary for editing a film. This is suitable for carrying in an automobile, train, etc. The apparatus is also readily adapted for placing in a suitable carton for shipping purposes. When folded out on a table, or other support, it automatically positions the two winding devices in proper location with reference to the viewing device and the splicing device, and presents all parts of the apparatus in convenient position for using.
