1 Claim.

This specification will disclose an improved book construction of the kind having a back portion and two hinged covers, between which all the pages, or filler, may be bound or unbound as desired, for changing the book contents. This kind of book construction is known and appears in various prior art forms. The new form to be disclosed is one having certain combinations with definite advantages, as will appear from the following description.

Fig. 1 is a plan view of book covers and back portion without contents;

Fig. 2 is a plan View of the book pages arranged for insertion as the book contents;

Fig. 3 is an edge view of the book with all elements assembled as a unit;

Fig. 4 shows a rod suitable for fastening the book contents in the book binder;

Fig. 5 is a plan and Fig. 6 is a sectional View on line 66 showing the metal plate mounted in the back portion of the binder; and

Fig. '7 is a detail view showing the assembly of the metal parts only.

The book binder of Fig. 1 is technically known as a case. It consists of the two covers I and 2 hinged to the curved back portion 3, all in one unit. In making up such a case for this invention, the curved metal plate 4 of Fig. 5 is fastened into the back portion, preferably by laminating it with the usual binding strips on the outside, as book binders will understand. Spaced bridges 6 are stamped out of this metal and extend upwardly so as to make small open arches on the inside of the back portion, see Fig. 6. This arrangement completes the case or binder seen in Figs. 1 and 3.

The book contents of Fig. 2 is an arrangement of sheets or pages 7, with spaced holes along their binding margins. A single helically coiled binding wire 8 is threaded through these holes, the wire having the pitch equal to the space between the holes. The binding of paper pads in this 1 way, as shown in Fig. 2, is well known and widely this way removably fastened in the binder case, v

see Fig. 3.

The combination of parts is a simple and effective one to make a very useful book. All that is added to the binder case, in the disclosed and preferred form, is'a single metal stamping 4.

The pad or book contents of Fig. 2 is of a highly desirable and known form of book unit. The binder case and its contents are brought into or out of book combination by the mere insertion or removal of one rod 9 to engage or disengage the two main elements. The rod may be so placed as to fit rather snugly between the binding wire coils 8 and the spaced arches 6. If this is provided for, as well as for a rather snug fit of the width of the arches between the coils, the assembly will be made in the preferred form. There will be enough spring action between the parts all along the back, due particularly to the springy nature of the coiled wire, as to hold everything without the shifting about in use which so often gives a sloppy, unsubstantial impression to removable binders. The new arrangement gives a removable binder for the particular kind of book filler so highly desirable to use on account of the inexpensive and efficient way in which the pages are bound to turn over easily and lie flat. The whole book in the form now disclosed and seen in Fig. 3 is a new and useful article in which the elements all coact.

Having described the invention and how it may be practiced, the following claim is made for its protection.

I claim: I

In a book structure-of the kind in which the filler sheets are hung on the closely spaced coils of a single binding wire and fastened to the back panel of the binder case by a rod Inside the coils and fastened to the back panel, that construction in which the back panel is curved transversely, a sheet metal stiffening plate built into the back panel over its whole area and shaped to hold the back panel form, a series of arches spaced along the whole length of the back panel struck up from the sheet metal of the back panel, the arches metal plate functions to both hold the curved form of the back panel as a functional part of said back panel and as a rod holding means by reason of its integral arches to nest the wire coils closely in said curved back panel under the rod 5 and between the arches.
