5 Claims." (Cl. 12919) .An object of this invention is. to provide a simple means of binding leaves. which means initially can be easily and cheaply produced and which, when in use, willsimultaneously expose to view "two or more. pages of the leaves bound. A further object of the inventionis to employ with such a binding means a ready means for attaching additional leaves at any time or withdrawing any previously attached leaf or leavestherefrom as desired. A still further'object of the invention is to produce a book structure comprising groups of leaves and binding means therefor arranged in a novel way, affording easy assemblage, disassemblage and advantageous, simultaneous exposures of leaves to view.

In the accompanying drawing wln'ch illustrates embodiments of my invention, Fig. 1 is a perspective view of a generally rectangular shaped. binder means formed of flexible mate-' rial. Fig. 2 shows two groups of leaves attached, respectively, to flanges or marginal hingesformed integrally with the body of the binder means of Fig. 1. .Fig. '3 shows two groups of leaves attached, respectively,to hinges of a binder means and two other groups of leaves attached directly to the body "or unflanged portion of the binder means, respectively, adjacent toa different one ofits flanges. Fig. 4 shows aperspective view of the modified form of binder used in attaching more than two groups of leaves asillustrated by Fig. 3. Fig. 5 shows a modification in which a hinge or, flange structure of special shape is formed separately from and'suitably attached to the body of the binder means. v f

In all figures the same reference letters have been applied to corresponding parts.

The letter A refers to'the binder body which opens and closes with reference to the leaves attached to it like the covers of a book. It is preferably formed of a sheet of tough paper, flexible throughout. I

D and E are flanges preferably formed integrallywith the body of the binder by folding over and desirably creasing marginal portions thereof. As illustrated, the flange D extends along substantially the full length of aside margin of the body of the binder. The flange E extends inwardly from the opposite side margin of the binderbodyv along approximately half of the width'of an end margin thereof. The inner extremity of the flange E isadjacent a line or region along which the side portions of the binder body foldorhinge with reference to each other. Small As shown in Figs. 2 and 3, leaves, indicated generally by the letter B, are arranged in a. group and attached by suitable means, such as paper fasteners F of ordinary form, to the flange D, along one side of the binder body A, and other leaves, indicated generally by the letter .C, are arranged in another group and attached by similar means to the flange E along an end marginal portion of thebinder body, Thus arranged, the groups of leaves B and C, or bcth of them, can be turned inwardly into contact with or outwardly from a juxtaposed body portion ofthe binder, and when both groups are so turned inwardly, they, together with the underlying portionsbf the binder, may be folded along a line, adjacent the juxtaposed edges of the groups of leaves.

Fig. 3 illustrates the modification inwhichthe binder means is of the form shown by Fig. 4, and one or more groups of leaves, b, c, are attached directly to the body of the binder, in addition to groups of leaves B and C, attached to flanges D and E, as shown by Fig. 2. Fig. 3 illustrates the group of leavesb, attached byfasteners F directly to the binder body, closely adjacent' to the flange D, extending. along the length of a longitudinal, marginal portion of the binder and the group of leaves 0, attached by similar means directly to the binder body, closely adjacent to the flange E, extending along a portionof the Width of a marginal end portion of the binder body. The arrangement of Fig. 3 issuohthat the respective groups of leaves B and'C, attached to flanges D and E, may be folded inwardly upon the respective groups of leaves b and e, attached to the binder body, and that thereafter the right and left portions of the binder means'may be folded toward each other, carrying with them both;sets of leaves, such binder portions then Figs. 2 or 3 are folded together in the, form of a I closed book, a flange, attached margin of one group of leaves lies immediately'adjacent an unattached edge margin of another group of leaves. This arrangement lends stability to the structure,

and enables it to withstand harder usage.

either one or two of the leaves of group B. .This I is often a great convenience as, for example,

when the matter transcribed on the leaves of group C calls for a comparison with thematter to be'found upon the leaves of group B, or vice versa. Similar advantages are obviously attainable in using the groups of leaves b and c of themodified form of Fig. 3, in reference to each "other or oonjointly with'the groups of leaves B V sufiiciently beyond the edges of the respective.

groups of leaves, b and c, attacheddirectly to the binder body to afford adequate anchorage for the other groups of leaves, B and C, attached to said flanges and to enable said flanges to fold over the adjacent edges of the groups of. leaves b andc in. a manner tobring thegroups of leaves B and C into superposed relations, respectively, with the leavesof' groups b. and c. The arrangement of Fig. 3 will be found advantageous when the groups of leaves are very thick and their manipulation or reading is rendered difficult for that reason. It will also be found a usefulmeans of segregating leaves of either or both groups that may carry different classes of matter. Fig. 5 illustrates certain modified, alternativ features of general mechanical equivalence to' corresponding features already described and having advantages characteristic of their specific structures. Fig. 5 shows only a portion of a completebinder structure but it will be obvious therefrom how the features revealed, orany of The attaching flange D for the group of leaves B shown, is, in this case,fformed separately from the binder body portion A and is suitably secured thereto. That flange is also formed of a wider strip of 35. material than any corresponding flange of the other flgures. In addition to the part thereof immediately attached tothe binder body, .it includes an upstanding? portion, G, of suitable width, folded directly back upon itself, and from this back folded'portion there extends outwardly a portion, H, affording a backing for a group of leaves. This backing portion I-I carries another upstanding portion, I, spaced from the back folded portion of G. There is thus formed'a generallywshaped pocket, of requisite size, for the reception of the marginal portion of a group of leaves to be attached to the flange. The fas-v tenersin this case traverse'not only the leaves of group B but also three embracing portions of theflange D. This affords a desirably strong means of attaching the leaves to the binder body, and one protecting and improving the appearance of the attached margin thereof.

As shown by Figs. 1 to 4, inclusive each binder body is of sufficient dimension,'to afford material fora hinge portion of a width adequate to admit of the cover or side portions of that body being folded together over attached groups of leaves lying between and upon them. There is no neces- .sity, ordinarily,-for giving any other attention known type of two pronged, headed paper fastener F, but any other equivalent fastening means 76 3 maybe emp While in the accompanying drawing the groups of leaves have been shown in each figure attached respectively adjacent a left-hand margin and a portion of the upper end margin of the binder,

this is to. be understood merely as a preferred manner of attachment and that the groups of leaves may be secured in a likemanner to other margins of the binder if desired. r r

The leaves of each or either group may be structurally independent of each other except t or otherwise as desired. a

I have found'my invention to be of especial utility in binding together copies of patents and for the means that attaches them tothe binder,

typed reports pertaining-thereto. I conceive it, however, to have equal or greater utility inother fields. For example, it will serve the needs of students who are provided with outlines of subjects in the form of leaves or pamphlets and who are required to make 'notesfof' pertinentlecturesj or reports of investigations. It'also affords a ready aid inthe preparation of indice's, and it could be used to advantagein the preparation of various educational devices such as charts or maps.

Many obvious modifications, adaptations and uses not mentioned herein will occur to those skilled in the art and fall within the scope of the appended claims. y V
