Patented Oct. 15, 1935 UNITED STATES FILM HOLDER Charles E. Bedaux, Monts, France, assignor to Eastman Kodak Company, Rochester, N. Y., a corporation of New York Application May 10, 1933, Serial No. 670,301

Claims.

This invention relates to a device for holding a loop film.

Heretofore troubles have arisen in storing or shipping loop film because when the same were coiled up or wound upon a support the looped ends were bent so sharply or folded so closely upon themselves that there was danger of breaking or cracking the film at those places. By this device a loop film can be coiled up and put in place and securely held in position in such a way that it can be readily removed when desired. At the same time the danger of a crack or break being made due to a sharp bend or bends in the loop of film is obviated. The device may be made of different sorts of material that possesses the desired degree of strength and rigidity. It can be made, for example, of thick paper or cardboard or thin metal, etc.

The invention will be understood from the description in connection with the accompanying drawing in which Fig. 1 is a plan view of an illustrative embodiment of the invention and Fig. 2 is a section along the line 2--2 of Fig. 1.

In the drawing reference character I indicates a sheet of material, such as wood, metal, celluloid, bakelite, etc. that is thick enough to possess a considerable degree of strength and rigidity. It is provided with a hole or depression 2 near one end thereof, which hole or opening is at least as large as the coil of film when the same has been coiled or rolled up. On one side of the sheet I around the periphery of the hole 2 there is provided a housing 3. This housing 3 is attached to the side of the sheet I around the periphery of the opening 2 in any convenient manner. For example, the edge 4 that is in contact with the sheet I may be turned outwardly and pasted, welded, riveted or attached in any other convenient manner to the sheet I. The housing 3 is circularand is of sufiiciently large diameter to contain the strip of loop film. It is of the same diameter as the depression 2 and the axial length of the .depression 2 and housing 3 may be the same or they may differ in length, if desired. The sum of the axial length of the depression 2 and housing 3 is preferably slightly greater than the width of the film.

The housing 3 is provided with an opening 5 of such diameter that when the loop of film has been called up it can be inserted through this opening 5. In the use of the device the loop of film is wound up, for example, around the finger into a sufficiently small coil to be inserted through the opening 5. When the film 6 has been inserted through the opening 5 it springs out so that its outside convolution'contacts with the inside surface of the cylindrical portions of the depression 2 and housing 3, although it does this without suificient force to cause the looped end at that point to be folded sharply upon itself. 5 The other looped end will of course not be sharply folded, as there is no appreciable pressure against it. When it is desired to remove the film this can be readily done by catching hold of the loose looped end and Withdrawing through the 10 opening 5.

The fiat portions-of the sheet I outside of the housing 3 can be utilized for insignia or information to identify the film and record whatever information is desirable in connection with the film, thus facilitating filing the films and ascertaining information relative thereto in a very convenient way. The device thus serves as a filing card which also functions as a container for a I loop of film. The card can be filed in a visible horizontal file or in a non-visible vertical file and the information thereon can be readily inspected.

It is not necessary to have a covering for the opening 5 as the fihn has suificient spring to keep it sprung outwardly into position in the depres- 5 sion 2 and housing 3.

Clips or hangers 1 may be passed through slits near one edge of the sheet so that such sheets can be hung upon Wires for filing them. In such a method of filing or storing the cards they may be hung so that the housings 3 are at alternate ends of the group, thus saving space.

I claim:

1. A film filing device comprising a sheet memher, and a housing which is attached to said sheet member, which is provided in ope side with an opening to permit insertion of a coil of film, and within which the coil of film may expand to a dimension greater than the least dimension of said opening. 40

2. A film filing device comprising-a sheet member adapted to receive identifying data, and a housing which is attached to said sheet member, which is provided in one side with an opening to permit insertion of a coil of film, and within which the coil of film may expand to a dimension greater than the least dimension of said opening.

3. A film filing device comprising a sheet memher having an area for identifying data, and a circular housing which is attached to said sheet member, which is provided in one side with an opening to permit insertion of a coil of film, and which has a diameter sufficient to permit expansion of said film coil to a diameter greater than the least dimension of said opening.

4, A film filing device comprising a sheet member having an area for identifying data, and a circular housing which is attached to said sheet member, which is'provi-ded in one side with a circular opening to permit insertion of a coil of film, and which has a diameter suflicient to permit expansion of said film coil to a diameter greater than the diameter of said circular openmg.

5. A film filing device comprising a sheet mem-
