G. LEVINSKY ET AL REMOVABLE STITCHING AND BINDING DEVICE Sept. 12, 1933.

Filed A rii 26, 1932 I-nv'en fora: G. Levi 714" If FIGA Patented Sept. 12, 1933 PATENT QFFIcE REMOVABLE STITCHING AND BINDING DEVICE Georges Levinsky and Charles Marsal, Paris,

France 1 Application April 26, 1932, Serial No. 607,644, and in France November 19, 1931 2 Claims. (01. 129-1) The object of the present invention is a removable device for stitching and binding which is intended to be applied to note books, account books, files, catalogues, books and similar objects. The device is more particularly characterized by the fact that it is composed solely of one single piece cut out of metal or any other suitable substance and comprising, in combination: 1-a flat part intended to be made solid with one of the flats of the binding; 2-a certain number of blades intended to form loops onto which the sheets of the book are to be threaded and 3-a turned-up edge provided with as many notches as there are blades to the device and into which the extremities of said blades are fixed.

On the attached drawing an embodiment of the invention has been shown as an example.

On this drawing the apparatus has been shown removed from the book as well as various stages in the fitting of it to the latter.

Figure 1 shows a note-book open, the two binding flats of which are connected to one another by the apparatus which forms the subject matter of the invention.

Figure 2 is a perpendicular section through one of the assembling loops of the note-book shown in Figure 1; Figure 3 is a plan view of the blank for the binding means as first formed;

Figure 4 is a vertical section of the apparatus as it appears when fitted to the note-book. This figure shows the manner in which the binding flats and the perforated leaves are introduced into the apparatus. This view corresponds with the first operation in the course of mounting;

Figure 5 is a section similar to that in Figure 4. This figure shows how each blade is looped and closed (the second operation in the course of mounting) finally Figure 6 is a plan view, with a portion removed, of the apparatus mounted on the note book. This figure shows how the extremity of the hook nests in the socket provided for it.

The device which forms the subject matter of the invention is cut out of a more or less thick sheet of metal, in the usual manner, as shown in particular in Figure 3. The part thus obtained is composed of an armature, or fiat piece, 1 intended to be applied to theouter surface of one of the flats of the binding. This armature is prolonged at one edge by a certain number of blades 2 which, in the course of the process of mounting, are at an angle of 90? to flat portion 1 which is provided, in addition, at the same edge with portions 3 intermediate the blades and turned back in the opposite directions, thus forming notches opposite the base portions of the blades.

In order 'to apply the device hereinabove described to a note-book or to an account-book, three very simple operations have to be performed:

The first operation consists in perforating the covers, or binding fiats, and the sheets leaving the same interval between the perforations as that which exists between the blades. It is of course understood that a certain amount of play is allowed between the blades andperforations 9 in order to allow the sheets to rotate freely along the said blades without catching.

The second operation consists in inserting blades 2 through perforations '9. The arrangement shown on Figure 4 is then obtained.

Finally, the third operation consists in bending blades 2 so as to form a loop, as illustrated in Fig-' ure 5, the extremity of each blade being inserted in the corresponding notch provided in turned-back edge 3 where it is thus firmly held. Extremities 4 and 5 of the flat part, or armature, 1 are then folded over onto the lower fiat, (or cover) '7 as shown on Figure 1; in this way a rapid mounting of the device is obtained, said mounting being perfectly rigid since the device is held in a longitudinal direction by the clips, or extremities, 4 and 5, while it is maintained transvers'ally by blades 2 held fast by perforations 9.

It is possible, without going beyond the scope of the invention, to bend the blades in the form of a loop, as shown in the drawing, or in the form of a square or of an oval. The sheets of the catalogue or book thus bound or stitched always remain in a strictly horizontal position when said catalogue or book is open thus considerably facilitating reading and also allowing writing to be done easily. Such is not the case with the bindings in current use in which the sheets assume a more or less bulging shape when the book or note-book is open.

Another advantage of the device which forms the subject matter of the present invention resides in the fact that it is always possible to place the upper cover of the binding underneath the lower cover by causing the upper cover to rotate along the curved blades the whole assembly returning to its initial position without damage or deformation.

This system of binding is absolutely removable since it can be readily dismounted and refitted an indefinite number of times. It also makes it possible, while retaining the same covers, to remove or to put back the sheets, and to increase their number, without dismounting the apparatus from the cover to which it is fixed. It is suflicient, indeed, to slightly open out the loops, without deforming the blades, in order to remove a certain number of sheets or to put them back in their position.

After such an operation the extremities of the loops are reinserted into their respective notches and the binding regains its original appearance.

When dealing with account-books of large size, armature 1 (Figure 3) can be given a curved section or be provided with ribs at one or several points in order to give it the required stiffness.

What we claim is:

1. A loose-leaf binding device adapted to be attached directly to a loose-leaf binder cover comprising a one-piece blank provided with a longitudinal portion adapted to be applied to said cover, a plurality of blade portions lying at right angles to one edge of said longitudinal portion, and turned-back portions forming an angle with the plane of said longitudinal portion, said turned-back portions lying at that edge of said longitudinal portion to which said blade portions are attached, said turned-back portion forming notches into which the free extremities of said blade port" "15 may be inserted.

2. In combination with the cover of a looseleaf assembly,--a detachable loose-leaf binder provided with a longitudinal portion of sufficient length to permit the ends thereof to be bent over the edges of said cover, a plurality of blade portions lying at right-angles to one edge of said longitudinal portion, and turned-back portions forming an angle with the plane of said longitudinal portion, said turned-back portions lying at that edge of said longitudinal portion to which said blade portions are attached, said turnedback portions forming notches into which the free extremities of said blade portions may be inserted.
