Filed April 29. 1929 s Sheets-Sheet a Patented Oct. 18, 1932 PATENT OFFICE I JAKOB BECK, or BERLIN, GERMANY FILE Application filed April 29, 1929, Serial No. 359,133, and in Germany November 12, 1928.

- sent however the inconvenience that the filing holes in the newspapers, books of music or the like, tear out easily or get wider at repeated use so that the filed papers get loose. To obviate this inconvenience it has been proposed to reinforce the paper edge or to i'nsertin the fold of the book a. wire, a strip of fabric or the like; These precautions are not only trouble'some and expensive but they do not prevent the books from getting loose as they cannot be maintained in the files.

It has further been proposed to provide on the inner surface of the back of the file at the filing points clamping springs on the one hand designed to securely hold the filed newspapers or books and on the other hand carrying pins engaging with the perforations of the filed newspapers, book or sheets. These pins are hingedly connected to the clamping springs and telescoped the one into the other, a special key being required for opening the filing pins. This inconvenience is due to the fact that the ends of the clamping springs are not accessible but hidden in the file back and situated underneath the edges of the cover back so that these files are not easy to manipulate and rather expensive.

All the above mentioned inconveniences are obviated by the present invention, according to which holding means for the filing pins are arranged on the back of tee file at the leafimpaling points, said holding means projecting over the edges of the cover and being controlled by resilient or elastic elements so that they strongly press together the filed sheets or hooks at the filing points.

These means for holding the filing pins may be of various constructions; they may consist As filing pins narrow or flat metal strips. 7 preferably of spring steel, are used.

Several embodiments of the invention are illustrated by way of example in the accompanying drawings in which Fig. 1 shows an open file in front elevation;

Fig. 2 shows on larger scale a cross-section through the open file. v

Fig. 3 is a perspective View of a clamping spring the ends of which form holding means for a filing pin. I j

Figs. l, 5 and 6 are different viewsof the clamping device in the file.

Figs. 7 and 8 show two other forms of construction of the holding means for the filing 6i! pins-formed by the ends of a clamping spring.

Figs. 9 and 10 are part views of filesifitt-ed with the file pin holding means shown in Figs.

7 and 8 respectively.

Fig. 11 shows in cross-section tion of the claw-like holding means shown in Fig. 8.

Fig. 12 shows a covering bar used with same. v

Fig. 13 is a section on line 13-13 of Fig.12 7 5 on larger scale. p

Referring to Figs. 1 to 6 clamping springs 2 in the form of fiat strips each bent so that its" ends are adjacent to each other are inserted in the back of the file 1. One of the 803?:

two ends of the clamping spring has an ex- After the periodicals have been filed on the filing pin 5, this pin can be inserted in the hook 4L and its free end inserted into the open end of the pocket 7 ofthe cover. The rear' end of the filing pin can be fiXed in the'left cover of the file, or both ends of the pin may be inserted into pockets 7 of the cover as shown in Figs. 11 and 14.

The perforations in the first and last sheets,

periodicalsand the like which have been filed the applica 711"} I cannot be widened by the filing pins, as the ends of the clamping springs forming the holding means for the filing pins project over the edges of the cover back and form a frame around the perforations.

Referring to Fig. '7 the pin-holding means consists of latches 8 in the ends of the clamping spring 2. As shown in Fig. 7 the ends of the clamping springs 2 are bent over so that they form a guide for the latches 8. The latches 8 are arranged longitudinally shiftable and hold the pins 5 tightly in that they grip over their arms (Fig. 9). Fig. 9 shows in top plan View a file 1 fitted with this fileholding means.

Figs. 8, 10, and 11 show claws 9 in the ends of the clamping spring, said claws designed to engage with corresponding depressions 10 of bars 11 Each bar 11 as shown in Figs. 10, 12 and 13 is of thin flexible material and preferably stuck on a sheet 12. A separate sheet 12 with a thin metal bar is preferably arranged on the inner surface of the correspending cover in all the different forms of holding means for the filing pins, in order to preserve intact the first and last sheets 01': the papers filed.

I claim 1. A file for holding the papers, books and the like to be filed, the pile of filed papers being compressed at the filing points, comprising in combination with the file back, the filing pins and clamping springs inserted in the file back at the leaf-impaling points so' that their ends project over the edges of the file back, said ends of said clamping springs constructed to form holding means for said filing pins.

2. A file for holding the papers, books and the like to be filed, the pile of filed papers being compressed at the filing points, comprising in combination with the file back, the filing pins and clamping springs inserted in the file back at the leaf-impaling points so that their ends project over the edges of the file back, said ends of said clamping springs constructed to form holding means for the filing pins, said holding means covering frame-like the perforations in file papers.

1 3. A file for holding the papers, books and the like to be filed, the pile of filed papers being compressed at the filing points, comprising in combination with the file back, the filing pins and clamping springs inserted in the file back at the leaf-impaling points, an

extension on each end of each of said clamping springs, projecting over the edges of the file back, one of said extensions having an eye and the other of said extensions having a slot adapted to engage in said eye to form holding means for said filing pins.

4. A file for holding the papers, books and the like to be filed, the pile of filed papers being compressed at the filing points, comprising in combination with the file back, the

prising in combination with the file back, the r filing pins and clamping springs inserted in the file back at the leaf-impaling points so that their ends project over the edges of the file back, latches in the ends of said clamping springs adapted to form holding means for said ling pins.

6. A file (with filing pins) for holding the papers, books and the like to be filed, the pile of filed papers being compressed at the filing points, comprising in combination filing pins, claw-like clamping springs inserted in; the file back at the filing points so that their ends project over the edges of the file back,

said ends of said clamping springs constructed to form holding means for said fil ing pins, separate sheets on the inner surface of the two covers, and a cover bar on each separate sheet having depressions adapted to receive said claw-like holding means.

In testimony whereof alfix my signature.
