3 Claims.

The present invention relates to a book binding consisting of folded and nested leaves secured together by stitches visible on the inner fold of the center pages where a so-called spread or two page advertisement or display usually occurs, and the invention relates more particularly to such a binding having a flat back. If the stitches are continuous along the fold they tend to mar the effect of the sprea and if the stitches are discontinuous and do not extend along the entire length of the fold the portions of the leaves be tween the stitches tend to separate or bulge at the folded portions of the pages presenting a detached appearance. Otherwise stated, when the book is open flat at a point between the cover and the spread certain of the leaves on the right-hand side are folded and the rest of the leaves are flat and the fold in the right hand leaves is detached from the flat leaves between the stitches and tends to bulge up. This is more pronounced at points near the cover.

The principal object of the present invention is to avoid the above mentioned defects and disadvantages and to reenforce the back and firmly connect the folded and nested or assembled portions of the leaves of a book at the back thereof and tie in the leaves between the stitches and prevent the folded parts of the leaves from pulling away from the flat parts of the leaves between the stitches when the book is open.

Generally stated, the invention consists in a book having a flat back and a cover and comprising folded and nested or assembled leaves stitched together and including a series of holes, pits or deformations arranged between the stitches and extending from the outside of the back inwards and having adhesive securing the cover and entering the holes, pits or deformations.

The invention also consists in nesting leaves into a folded assembly providing a peaked back, flattening the back by the application of pressure, making holes, pits or deformations inward from the outside of the back, inserting adhesive into the holes, pits or deformations and applying it to the back and fastening the cover to the adhesive at the back of the book.

Other objects of the invention will appear from the following description and the invention further consists in the improvements to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawings forming part hereof and in which,

Figure 1 is a perspective View illustrating a Figure 5 is a view partly in section further 10 illustrative of the invention.

Figures 6 and 7 are perspective views illustrating respectively the inside fold and the back with the cover removed of a book embodying a modification of the invention.

15 Figures 8 and 9 are top and sectional views illustrating a modified form of hole, pit or deformation; and

Figures 10 and 11 are similar views illustrating further modifications. 2

Referring to the drawings, more particularly Figures 1 to 5, there are a series of holes, pits or deformations l and they are arranged in a row and they extend from the back of the book inward. 2 indicates an adhesive entering the holes and it also is applied to the back of the book. The cover 3, Figure 2, is secured at the back of the book by the adhesive 2. The described holes, pits or deformations l in and of themselves have a tendency to connect the various leaves, because in their production the leaves are deformed at the rims of the holes and the deformations extend into one another and in that way serve to inter-- lock or connect the leaves. Of course, the adhesive entering the holes provides a bond between 3 the leaves.

The book shown in the drawings is the product of the method of my application No. 7,965, filed Feb. 25, 1935, and it is characterized by a well defined fiat back, while the present invention is 40 particularly applicable to a book of that character, it is not in all cases limited to such a book.

According to the present invention leaves 4 are nested and folded into an assembly which would have a peaked back, as shown in Figure 4, but 4 the back is flattened by the application of pressure, for example, by a roller 5, Figure 5, acting in association with a saddle 6. During this operation the holes, pits or deformations I may be made by means of a punch or series of punches 5 of which one is indicated at l in Figure 2.

The construction and mode of operation of the modification illustrated in Figures 6 and 7 are as above described except as follows: Groups of stitches 'l are shown in spaced relation and 55 they extend from the inside at the fold through the back of the book and they may be of thread or wire as preferred. Between the stitches and from the outside of the back inward extend holes, pits or deformations I which do not reach through all the leaves and therefore do not appear at the inside of the book and do not mar the spread. The function of these pits, holes or deformations is to connect the leaves between the stitches I and prevent bulging when the book is open between the flat leaves and the folded leaves.

The pits, holes or deformations may assume various forms. As shown in Figures 8 and 9 they are in the form of tongues l and the tongues are bent inward thus afiording a good connection between the folds of the leaves. In Figures 10 and 11 the tongues l are pointed and operate in the same way.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing from the spirit of the invention which is not limited in respect to such matters or otherwise than as the prior art and the appended claims may require.

I claim:

1. A book having a cover and a flat back and nested folded leaves and a series of depressions extending from the outside of the back inward and stopping short of the inside center fold, and having an adhesive uniting the cover and entering the depressions.

2. The method of binding books which consists in nesting and folding leaves into an assembly having a peaked back, flattening the back by the application of pressure, making depressions inward from the back and stopping short of the inside center fold, inserting adhesive in the holes and applying it to the back, and fastening the cover to the adhesive at the back of the book.

3. A book comprising nested folded leaves having stitches for securing them together and including depressions arranged between the stitches and extending from the outside of the back inwards and stopping short of the inside center fold and adhesive entering the depressions.
