2 Claims.

My invention relates to a new and useful improvement in books and has particular reference to means by which book signatures comprising a plurality of sheets, pamphlets, price lists or the like, can be easily and quickly secured to the back of a book and in such position that they become, for practical purposes, a permanent part of the book.

Another and further object of the invention is the provision of means by which a pamphlet, price list or like supplement can be easily and quickly secured to the back cover of a book and also easily and quickly removed from the book without in any way damaging or injuring it, and a new supplement, pamphlet or price list placed in the book in the position formerly occupied by the removed pamphlet, thus enabling the user to keep the book up to date.

Another and further object of my invention is the provision that the maker or printer of a pamphlet or supplement without much additional labor and at very small additional cost, at the time of completing such pamphlet or signature, apply a binder trip which renders the pamphlet or signature ready with little effort and without the use of tools of any kind to insert it in a book in such position that for ordinary purposes it forms a part of the complete book.

A further object of my invention is the provision of an improvement in books in which means are provided for the insertion of a supplement, such as a price list or pamphlet, in the rear cover thereof, and in which the insertion is secured to a binder strip in such manner that it can be torn loose without defacing the book in any way, and a new supplement inserted quickly and easily without defacing or altering the book.

These and other objects of my invention will be more readily and better understood by reference to the accompanying drawing, and in Which- Figure 1 is an elevational View of a book with the covers opened, embodying my invention;

Figure 2 is an end elevational view of a book partially open, showing a pamphlet inserted in the back cover thereof;

Figure 3 is an end View of a signature showing a binding strip attached thereto; and

Figure 4 is a diagrammatic cross-sectional view of one of the binding strips attached to the signature as shown in Figure 3.

Referring now specifically to the drawing, and in which like reference characters refer to like parts throughout, a book I is shown made up of pairs of leaves folded along the center into signatures II, which are bound, stapled or otherwise secured together, and have a front cover page 12 and rear cover It? applied thereto in the usual manner. A pamphlet, designated as a whole as M, is composed usually of a plurality of sheets folded along their centers into signatures and stapled together by means of a staple l5, or stitched or otherwise secured together. A binding strip I6 is employed having one side completely coated with dried adhesive H, such as mucilage, glue or the like. On the opposite side of the binding strip [6 a coating of adhesive I8 is applied which extends along one marginal edge, preferably the rear one, and to a point approximately one-half the width of the binding strip l6, so that a free area I9 is provided upon which no adhesive is placed.

In making up the pamphlet or signatures to be inserted in the cover of a book, they usually comprise, as shown, a plurality of leaves stapled together by staples I5, 15. The binding strip [6 is secured to the face of the outer signature sheet near the fold line by moistening the adhesive 18 and pasting the strip to the outer face of one of the leaves of the signature near the fold thereof, so that thebinding strip I6 is secured to the outer signature sheet of the pamphlet M by only approximately one-half the width thereof. In this condition the pamphlet may be forwarded or delivered to the catalog or book owners and the pamphlet or signature placed inside the rear cover of the book by moistening the adhesive I"! on the face of the strip l6 and pasting the binding strip against the face of the cover on the inside thereof adjacent its rear edge. In this way the entire width of the binding strip I6 is secured against the inner face of the cover [3 near the fold line of the rear cover and the pamphlet secured for practical purposes permanently in position.

Should it become necessary or desirable to remove the pamphlet after it has been secured in position, it can be torn loose from the binding strip quite easily due to the fact that only approximately one-half of the area of the binding strip has adhered to the pamphlet and to the further fact that the pamphlet usually is made of a cheaper and less tough quality of paper than that used for covers of books. If desired, a new pamphlet, such as shown in Figure 3, may be inserted in the book as hereinabove described, by merely moistening the adhesive I! on the face of the new binding strip and superimposing it upon the surface of the binding strip left adhered to the rear cover upon the removal of the old pamphlet. In this manner a number of pamphlets, price lists and the like can be removed from and inserted into a book because the binding strips are quite thin and several can be inserted without interfering in any way with the proper closing of the book covers. If desired, supplemental pamphlets also may be inserted in a book at the front thereof without interfering in any way with the book or the functioning of the covers, if for any reason it should be desirable to retain the pamphlet or price lists at the rear of the book.

It will thus be understood that by the use of my improved method, several pamphlets may be placed in a book very easily and quickly, and much more cheaply than the practice usually followed of making binder strips which are stapled into the signature sheets or of making pockets on the back cover of a book, with cardboard insert pieces being attached to the rear faces of the supplements for insertion into the pockets. All of this not only adds to the expense but increases the thickness of a book unduly. Through the use of my improved method, several supplemental pamphlets can be inserted in a book and removed and others inserted in their place Without adding particularly to the bulk of the book or unduly increasing its thickness.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of the appended claims.

What is claimed is:

1. In combination with a book, of a supplement therefor comprising a plurality of signatures secured together, and a binder strip secured to the outer side of one of the signatures adjacent the fold of said signature and extending longitudinally thereof, the entire surface of the binder strip on one side being secured to the book and being secured by approximately one-half of its face along its rear marginal edge to the signature sheet, the remainder of the face of the binder strip being free.

2. In combination with a book, of a supplement therefor comprising a plurality of signatures secured together, and a binder strip secured to the outer side of one of the signatures adjacent the fold of said signature and extending longitudinally thereof, the binder strip having the entire area of its surface on one side secured to the book and approximately only one-half of the width of the surface of the opposite side of the binder strip secured to the signature and having its rear edge substantially parallel with the fold of the signature sheet.
