6 Claims.

'I'his invention relates to binders for ledger sheets, books, magazines,`catalogues, and in fact sheet material of virtually any sort of substantially uniform size, at least in one dimension. An 5 important object of the invention is the provision of a binder of simple and inexpensive construction adapted to very rmly hold papers or pamphlets bound therein in permanent or semi-permanent form yet without tightly clamping the sheets together at their bound edge, and so designed that the binding of material therein may be very quickly and easilyrdone, without the use of tools, and that'the bound material may be removed with equal ease when desired.

A further object resides in the improvement of the constructions disclosed in my previously issued patents, Nos. 1,688,514; 1,791,784; 1,825,257; issued Oct. 23, 1928; Feb. 10, 1931; and Sept. 29,

1931, respectively.

tion, and wherein similar reference numerals designate similar parts throughout theY several views.

In the drawings:

Fig. l is a perspective View showing in vertical section a portion of a binder incorporating the principles of this invention, a quantity of material bound therein also being shown and the cover removed.

Fig. 2 is a plan View showing the top of the binder, and, fragmentarily, the material bound therein.

Fig. 3 is a fragmentary perspective view of the binder fullyvopened and empty.

Fig. 4 is a perspective view of portions of a pair of the retaining members, showing the same spaced from each other but preparatory to being interfitted.

Fig. 5 is a View similar to Fig. 3 of a somewhat modified form of the invention, showing certain parts removed and spaced from the rest;

and

Fig. 6 is a view similar to Fig. 4 of equivalent portions of the modified binder.

In the drawings, the cover boards of my improved binder are designated l0 and may be of any suitable construction. They are each hinged along one edge to a substantially ilat back portion l2 in the conventional or any desired manner, as by means of the covering material Il. The back is adapted to support the holding elements for the bound material.

In the form shown in Figs. 1 to 4 inclusive the holding means includes a limp supporting member i4, which may be formed of cloth or leather, extending across the inside of the back portion l2, and 'secured in any suitable fashion, as by gluing. Its ends may project partly across and be secured to the cover boards I0, being shown trucked beneath the inner finishing cover I6 to strengthen its support and the hinging connections between the sides'and back. Adjacent each hinged corner l0 of the covers and back the material of which the member N is formed is folded to form elongated tubular securing loops l5 extending along substantially the entire length of the back.

The tubular securing loops are adapted to receive sheet metal fastening strips il, which are preferably formed of soft and easily bent metal, such as thin brass. The strips il will be seen to be so arranged that when the covers are closed they lie substantially parallel thereto and serve as abutments between which the bound material may be conned at its bound edge.

The retaining assemblies for the bound material are arranged one at each end oi the back and attached to the cover by means of the strips Il. Each may comprise a pair of telescopingly intertted sheet metal members lil-29, lying flat against the back and each provided with an integral inwardly bent portion 2l-2?! respectively adapted to lit into slots in the bound material to lock the same in the binder. Also integrally formed at the ends of the locking portions 214-22 are looped strip portions 23-24 forming slide- Ways adapted to slidably receive the strips I1. Elements lil-2U of the retainer assemblies are additionally held in slidably intertting relation by the overbent inner edge portion 25 of the outer member 20, which, cooperating with the overbent outer portion 22 serves to slidably conne the member I9. 40

It will thus be seen that members I9-2El are capable of limited expansive and contractive .movement to somewhat change the capacity of the binder, and that they may also be moved toward and away from each other. when the strip portions I 'l are straight, or held against such separating movement by simply bending over the ends of strips Il' in the manner indicated at Il in Fig. 3.

The bound material, shown in Figs. l and 2 and designated 30, is initially provided across its top and bottom, near the back edge, with a transverse slot, designated 3|, into which the portions 2 |-22 of the retaining members I9-2 are adapted to t when forced thereinto by pushing the members together as far as the material will permit, in the manner indicated in Fig. l. En this locked position they may be held and the bound material thus tightly secured by bending over the strip il as above noted, while by simply straightening the strip and separating one of the retaining assemblies from the other, the material may be quickly removed, as will be readily apparent.

In the modified construction shown in Figs. and 5 like reference characters have been applied to equivalent portions, with the addition of the distinguishing figure ct. K be constructed and positioned similarly to the member of the embodiment rst described, although inwardly projecting folded portions l5 thereof need not be separable to adapt them to receive devices Within them, since the strips li are dispensed with in this construction. The retaining members lila-lla are each provided with overbent end portions 2id and 22a adapted to enter the slots in the bound material in an analogous manner, and from the tops or" the overbent sections project elongated securing portions adapted to be bent down over the outside of the members iii when the material to be bound has been inserted in the binder and secured in place by forcing the retaining members together and their overlapped portions l-Za into the slots in such material. To prevent separation of the retaining assemblies the portions sli are secured to the members l5, and to the bound material in addition if desired, by means of tack-s Si, driven through the ends of the strips 35 and portions i5 and into the bound material. t will be seen that when the covers are closed the tacks are locked against removal, While they positively prevent endwise movement of the retaining assemblies away from each other at all times, as a result or which the retaining members function similarly to those of the first embodiment to lock the bound material securely in the binder, while if it is desired to remove any of the bound material, it is simply necessary to pull out one pair of tacks 3i and separate one retaining assembly from the other, after which reinsertion or replacement of material may be made by a simple reverse operation.

While it will be apparent that the illustrated embodiments of my invention herein disclosed are Well calculated to adequately fulfill the objects and advantages primarily Set forth, it is to be understood that the invention is subject to variation, modication and change within the spirit and scope of the subjoined claims.

What I claim is:
