BINDER.

Patented Apr. 13, 1920.

Application filed May 12, 1919. Serial No. 296,531.

To all whom it may concern:

Be it known that I, EMIL R. WVOHLER, a citizen of the United States, and a resident of Chicago, Cook county, and State of Illinois, have invented certain new and use ful Improvements in Binders, of which the following is declared to be a full, clear, and exact description.

This invention relates to binders and its principalobject is to provide improved and efficient means for binding together sheets of paper, such as bills, letters, or other memoranda. Another object is to provide a binder in which the sheets of paper may be temporarily or permanently bound together at one corner, whereby practically all of any sheet may be exposed by turning back sheets thereabove along one corner of the binder. Another object is to provide a binder for the corner of sheets, with means for positively holdingthe edges thereofv in an even condition and with other means for securing them together. Another object is to provide a binder which may be used for filing the sheets in vertical position and which permits the sheets to be laid on a desk or table, whereby they may be paged over and turned back at one corner to expose the desired sheet. With these and other objects in View, this invention consists in the several novel features hereinafter fully described and claimed.

The invention is clearly illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a binder, embodying a simple form of the present invention, and showing fragments of sheets bound therein, the view illustrating the bound sheets held in a vertical position;

Fig. 2 is a perspective view of the binder, showing the bound sheets laid upon their sides;

Fig. 3 is a section of the binder taken on the line 3-3 of Fig. 1 and showing two sheets held therein; V

Fig. 4 is a section of the binder taken on the line M of Fig. 2; I

Fig. 5- is a perspective view of the main corner member of the binder, and

Fig. 6 is a perspectiveview of the end member of the binder.

Referring to said drawing, the reference character 7 designates the corner member of the binder which, in itspreferred form, is made'of sheet metal struck up with suitable dies, and comprises two sides, .8, 9, which are disposed at right angles to each other, and an end 10 also disposed at right angles to the

sides

8, 9, as is clearly illustrated in Fig. 5. The end 10 is substantially triangular in shape and its edge 11 extends at an angle of approximately 45 degrees with the corners 12, 13. Opposite the end 10 of the corner member 7, is an end mem ber 13, which is also substantially triangular in shape and has two flanges, 14:, 1 1, disposed at right angles to each other, and adapted to embrace the

sides

8, 9, of the main member 7, as is clearly illustrated in Figs. 1 and 2. The edge 15 of the end member 13 is disposed at an angle of approximately 15 degrees to the flanges 14:, 14;, and is the edge across which the leaves are turned back to expose any of the bound leaves.

Extending through the end 10 of the member 7 is a screw or other threaded pin 16, which has a head 17 preferably held in a counter -sunk portion of the end 10. Upon the outer end of the screw-threaded pm 16 is a nut or other internally threaded clamping member-18, which is arranged to bear against the outer face of the end member 13 to thereby secure it upon the corner member 7 and to bind the leaves or sheets together.

It is preferred to use a piece of cardboard or other stiff material 19, at the end. 10, which cardboard forms the bottom of the binder when the bound sheets are laid upon their sides. I prefer to fasten said sheet of stiff material in place at the end 10, and have illustrated a nutsQO threaded upon the threaded stem 16 and bearing against said strip of stiff material, as is clearly illustrated in Fig. 3.

The sheets or leaves 21 are provided with perforations 22 for the reception of the threaded pin 16, and said perforations are made in the sheets near their lower left hand corners and at such points as to bring the edges 23, 2 1, of the sheets in contact with the inner faces of the an -ularly disposed sidesS, 9, of the corner member 7 whereby, when said sheets are secured upon the threaded pin 16, the edges thereof will be positively held in an even condition, thereby giving a neat and finished appearance to the bound sheets.

Obviously, any number of leaves or sheets less than the full capacity of the binder may be secured. together by the binder, and

other sheets may be added thereto until the full capacity of the binder is reached. To secure any number of sheets less than the number filling the capacity of the binder, or to add any others thereto, the nut 18 and end member 1.3 are first removed from the screw-threaded pin 16, the sheets slipped upon the pin 16, and the end member 13 replaced upon the pin and moved down along the inner faces of the

sides

8, 9,-as shown in dotted lines in Fig. 3, and brought into contact with the sheets and the nut 18 replaced on the screw-threaded stem and turned down against the end member 13. In this way a few sheets, or as many as are placed upon the stem, may be firmly held in place. When the full capacity of the binder is reached, the cardboard, or other stiff material 19, and nut 20, may be removed if desired, and the sheet of still material 19 may be replaced by a thinner outer sheet or cover and a similar cover sheet 9 5 placed on the opposite side of the stack of leaves, and the whole replaced upon the stem 16 and fastened together by the end member 13 and nut 18.

Conveniently, an index card 26 may be placed upon the outer face of the side 8, of the corner member 7, and held in place thereon by tongues 27 struck up from the body of the side 8 and bent down a ainst the outer face of the index card, as is 0' early shown in Fig. 1.

It is preferable to construct the corner member and end member of light gage sheet metal for the sake of obtaining lightness, and it is also desirable that the end walls of the corner member and end member should be reinforced or made of suitable thickness to withstand the strain placed upon them by the bolt and nut which tie the parts together. In Figs. and 6 l have shown the corner member and end member as formed of light gage sheet metal, the end walls being formed of double thickness of metal. In forming the end 10, of the corner member one ply 10 is folded. up from the side 9 and the other ply 10 is folded forward from the side 8. The edgeportion'10 of the ply 10 is folded over the edge of the ply 10 and crimped down upon The end wall of the end member 13 is shown -.as constructed in the same manner.

The bound sheets may be conveniently stored in upright position in suitable pigeon holes or on shelves or racks, as seen in Fig. 1 the-index card being exposed to view, and furnishing information for the selection of the proper. group of bound sheets. lVhen it is desired to examine any bound sheet, the .propergroup is selected and laid upon its side, as shown in Fig. 2, in which position the sheets may be turned. back along the edge 15 of the end member 1310 expose the desired sheet. If it is desired to insert a sheet at any place among the other sheets, the nut 18 and end member 13 are removed, the sheets separated from each other at the proper place, the sheet inserted and the sheets replaced on the stem and secured in place by the end member and nut.

I claim as new and desire to secure by Letters Patent:

A binder comprising a corner member consisting of two sides and an end disposed at right angles to each other to leave one open end, the two sides forming guides for one corner of the bound sheets; an end member for closing the open end of the corner member, and adjustable connecting means between the end of the corner member and the end member, at least one end member having an oblique edge over which the sheets may be turned back.
