METHOD OF BINDING BOOKS Filed Dec. 11, 1955 Patented Aug. 3, 1937 PATENT OFFICE METHOD or BINDING BOOKS Allen L. Grammer, Meadowbrook, Pa., assignor to Curtis Publishing Company, Philadelphia, Pa., a corporation'of Pennsylvania Application December; 11, 1935, Serial No. 53,898

2 Claims.

The principal'ob-ject of the present invention is to improve the appearance of the back and adjacent portions of a book consisting of folded and nested. leaves as well as to facilitate the turning of the leaves.

I The invention consists in flattening and molding the back portion of the assemblage of folded and nested leaves by the application of pressure to the back in the direction of the plane of the 0 leaves and also laterally to the adjacent portions of the leaves in directions inclined to that plane.

The invention also consists in the improvements to be presently described and finally claimed.

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

Figure 1 is a diagrammatic perspective view illustrative of a book embodying features of the invention.

Figure 2 is a perspective view illustrative of the manufacture of the book.

Figure 3 is a sectional view illustrative of the application of the present invention to the manufacture of books, and

' Figure 4 is a view similar to- Figure 3 illustrating a. modification.

Referring to the drawing,

The book consists of nested and folded leaves I The back portion of the book 2 is wider than the adjacent portions of the leaves and it slopes inward, as at 3, towards the sides of the book. By the described construction an attractive appearance is imparted to the book and the leaves are well secured in the binding. The sloping portions 3 provide a hinge construction which facilitates opening or turning the leaves. In my application Serial No. 7,965, filed February 25, 1935,

a which has matured to Patent Number 2,066,620,

eral consisted in assembling or nesting folded leaves into an assemblage having a peaked back 4 and flattening the back by the application of pressure, for example, between a roller 5 and. a saddle 6, Figure 3. Substantially this is done in 5 the present invention but in it not only is the back flattened but it is also molded. The molding is accomplished by the application of pressure laterally to the portions of the leaves adjacent to the flat back. The beveled rollers indicated at 10 'l, in Figure 3, are one means for accomplishing this purpose. In Figure 4 rollers 8, whose axes are inclined and divergent, are shown, and they, together with the roller 5, exert pressure not only edgewise on the assemblage, but also side- 15 wise and thus mold the back into the form desired.

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. 25

I claim:

1. The method of binding books which includes making an assembly of sheets with a peaked back, flattening the back by pressure applied in the direction of the plane of the leaves, and inwardly moulding the portion of the book adjacent the back by pressure exerted at an inclination to said plane.

2. The method of binding books which includes flattening and moulding the back portion of an assemblage of folded and nested leaves by the simultaneous application of pressure to the back in the direction of the plane of the leaves and also laterally to the adjacent portions of the leaves in directions inclined to that plane.
