7 Application filed 9,
To all-whom it may concern: 7
Be it known that I, GUYSFRY, a citizen of the United States, and a' resident of Yonkers in the county of WVestchester and State'of New York, have invented'a new and Improved Bookbinding, ofwhich thefollowing is a full, clear, and exact descrip.
correspondingfside of the book body portion.
Another object resides in a sufficiently flexible connection between thestiffportion of the cover and the edge of'the body portion of the book to which it is hinged to permit the cover portion to be swung completely around beneath the body portionand lieadjacent the other cover portion withou any strain whatsoeveron the parts;
' A further object resides in the particular Construction and arrangement of parts which are hereinafter describedand claimed. andfshown in the accompanying drawings.
The invention 'is illustrated in the drawings, of which Figure 1 is a perspective view of a book showing one of the cover portions swung around and lying beneath the under face of the body portion of the hook. i
Fig. 2 is a longitudinal cross section of the body portion showing it with one element of the flexible cover portion or connection attached. V
Fig. 3 is a similar section showing a further step in the arrangement of the flexible connection. 7
Fig. 4: isa similar section showing the cover portion in its normal relation to the body portion.
I Fig. 5 is a similar sectionshowing the relation-of one of the cover portions when it is swung around beneath the book or body portion.
The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention.

is, of course, only one application of the idenand the binding is adapted to be at tached to a body portion 1. *A tough, strong fabric, preferably in the form of a continu- 7 one sheet of material 2, is bound to the desirededges of the leaves of the body portion '1 and the free'portion thereof is then bentback, as shownin Fig. 8. That part of the free'portion which abuts the section of the sheet bound to the body portion of the leaves is connected thereto by any suitable means, such as adhesive. V
fThe free edges are then bent forward so that adjacent the bound edges of the body portion 1 there [2116 three folds of this binder material. The" purpose of bending the binder strip back into the position shown in Fig. 3 isthat when the'free portion is bent forward again intothe position shown in t, the pivotline of the strip and,
consequently, the pivot. line of the cover which is fastened to thestrip will be sub-' stantially coincident with the rear'edgeof the body portion. 'Theadditional length'of 1 material is connected in any suitable-man- '80 her, such as by gluing, to the inner portion ofacover/ This cover portion comprises relatively stiff portions 3 and whi'ch are connected together by a relatively flexible portion 5 These lengths of the flexible portion of the cover are indicated by the numerals 6 and 7, and it is to the inner faces of these portions and the adjacent portions of the 3'and l of the cover that the binder element 2 is fastened in the manner above described.
Asshown in Fig. 4;, I have, therefore, a cover portion for both the upper and lower faces of the body portion of a book. i Each of these cover portions comprises a stifi portion between which and the bound edge of the book is disposed a relatively flexible cover portion. one edge of the flexible por tion being suitably connected so that the flexible and the stiff portions can be swung around this bound edge to dispose the stiff m5 portion underneath the book. The length of the flexible portion, by being at least equal to the thickness of the book, permits this disposition of the stiff portion of the cover without any strain on the parts of the book.
which extends from one edge of 85 one stiff portion, around the bound ed 'es of Therefore, if a person wishes to fold the to p cover back in this manner, he can do sovrithout injuring the binding,and is enabled to use the book and turn the pages thereof without having the book occupy any more space than necessary, the leaves of the book, of course, being flexible enough to be folded beneath the book without injury. It is, of course, understood that the detail manner of making the binder element and the parts of the cover portion are only illustrative as to one means of relating them, other methods being adaptable to produce a book involving this inventive idea.
- It is to be observed, therefore, that I have provided a simple, eiiicient, strong, durable binding between the body portion of a book and the cover. This cover is hingedly connected to a body portion by having a flexible part thereof disposed between a relatively stiii part thereof and the hinge, the fleizible portion beingat least equal in length to the thickness of the book to permit the disposition of the cover as above referred to, and hinged to the body portion along the line coincident with the rear edge of the body portion.
What I claim is:
1. In coinhina n with the body portion of a book, a flexible binder element disposed around the bound edge of the body portion, said eleinentcc-nnected along certain portions to the body portion and having free ends, a cover having a flexible portion connected to the free ends of the binder ele- Inent-,.a-nd relatively stiff portions connected to-the flexible portions, the (lll'D-GDSlODS of the free ends of the binder element and the flexible portion of the cover permitting either one of the stiff portions of the cover to be swung around beneath the body portion without straining the binding.
2. In combination with the body portion of a book, a cover portion pivotally connect ed thereto, the pivot line being substantially coincident with the line of the rear edge of the body portion, said cover portion adjacent the pivot line being flexible, said flexible portion having a widthat least equal to the depth of the body portion.
3. In combination witha book body portion, a binderstrip fastened along: its intermediate portion and the rear surface of the leaves of the body portion and also along the rear edges of the outer leaves of the iody portion a short distance therealong from the rear edge of said leaves, the tree portion of the binder strip being, bent backward on itself and then bent forward again, the line of binding occurring along a line substantially coincident with the rear edge of the body portion,a cover portion cornprising flexible sections and stiff sections, the flexible I sections passing around the bound end of the body portion of the book being fastened to the binder strip, the free ends of the binderstrip being connect-- ed to the still part of the cover portion, the flexible sections of the cover portions ertending along the body portion a distance at least equal to the depth of the body portion so that the stiff part of the cover portion can be bent around beneath the body portion without straining the binding.
