Pareri IBOOKBINDING Application led. May 16, 1931. Serial No. 537,943.

This invention relates to bookbinding and has particular reference to a method of and means for binding books, especially those from which the binding has become detached and which require to be rebound.

@ne important object of the invention is to provide improved means for binding books, which means is simple in its nature and requires no great skill or experience in its application.

A second important object of the invention is to provide an improved binding which consists of but few and simple parts and does not require that any of the parts be stitched.

A third important object of the invention is to provide a new method of binding a book which may be practiced by unskilled persons.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in thev accompanying drawings and specifically claimed.

The invention further consists in a novel method of book binding also fully illustrated and described and specifically claimed.

ln the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a section through the back portion of a book bound in accordance with this invention.

Figure 2 is step in the application of the invention.

Figure 3 shows the second step therein.

Figure 4 shows the third step therein.

Figure 5 is a perspective view showing the rear upper portion of a book bound according to the invention, the view being partly broken away to show the construction.

Figure 6 is an enlarged detail section showing the condition of the glue upon completion of the third step.

For the full understanding of the invention there has been here shown at 10 the back portions of the leaves of a book preferably arranged.v in signatures in the usual manner. These leaves may be supposed to be unbound, either in the original state or forming part a similar view showing the first P of a book from which the binding has been lost or removed. Tn the latter case the glue, fabric and so forth is scraped off the back by a suitable instrument so as to leave the signatures in such condition that glue may penetrate between them. A glue coat 11 is now applied to the back with the backs of the signatures in an even plane, the'signatures being suitably held tightly together.- A backing strip 12 of suitable fabric is now provided, this strip being of a length corresponding to the length of the back and of a width considerablyl greater rthan the thickness of the gathered signatures. This vstrip is laid on aiiat surface and the freshly glued signatures pressed down thereon centrally of the strip so that it projects equally on both sides of the bundle of signatures. The signatures and strip are now lifted and the back rounded up by a suitable percussion implement such as a hammer or mallet. This beating up operation is performed while the glue is still in a plastic state so that portions of the glue are forced between the signatures as best shown in Figure 6, the glue also penetrating 5 the fabric to some extent as likewise shown in thatiigure and in Figure il. The glue is now allowed to harden. Next the projecting edges of the strip 12 are coated, on the side away from the signatures, with paste or glue and attached to the front and rear cover portions of Vthe binding proper 13. Finally finishing strips 14 are glued to the projecting ortions of the strip 12 and to thefront and back lea-ves of the bundle of signatures.y This completes the binding;y l There has thus been yprovided a simple and efficient binding for books and method of applying the same. j-Y

- It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. Tt is not, therefore, desired to confine the invention to the exact form herein shown and described, but it desired to include all such as properly come within the scope claimed.V v

Having thus .described the invention, what is claimed as new, is:

1. In a binding for a bundle of book signatures, a glue coat covering the back of said bundle and penetrating slightly between adjacent signatures, a backing strip held by the glue coat to the bundle of signatures and eX- tending laterally to each side of said bundle, abinding proper having front and rear cover portions land having the projecting portions of the binding strip adhesively secured to the rear parts of said cover portions, and finishing strips adhesively secured to the front and rear signatures and to the projecting portions of the backing strip.

2. The method of binding a bundle of signatures which includes coating the back of the bundle with glue, applying a backing strip wider than the bundle to the coated back in such manner as to cause the strip to project on both sides of the bundle, and beating up the bundle with the strip applied thereto While the glue is plastic to force the glue between the signatures and into the backing strip.

3. The method of binding av bundle of signatures which includes coating the back of I the bundle with glue, applying a backing strip Wider than the bundle to the coated back in such manner as to cause the strip to project on both sides of the bundle, beating up the bundle with the strip applied thereto while the glue is plastic to force the glue between the signatures and into the backing strip, allowing the glue to harden, and coating the outer surfaces of the projecting portions of the backing strip with adhesive and applying them to the rear inner faces of the cover portions of a binding proper.

4. The method of binding a bundle of signatures which includes coating the back of the bundle with glue, applying a backing strip wider than the bundle to the coated back in such manner as to cause the strip to project on both sides of the bundle, beating up the bundle with the strip applied thereto while the glue is plastic to force the glue between the signatures and into the backing strip, allowing the glue to harden, coating the outer surfaces of the projecting portions of the backing strip with adhesive and applying them to the'rear inner faces of the cover por- Y tions of a binding proper, and adhesively securing finishing strips to the bundle and backing strip in the angles between said bundle and the projecting portions of saidpbackmg strip.

5. The method of binding a bundle of'signatures, coating the back of the bundle with an adhesive so as to soften the parts so treated, a backing strip applied to the bundle, beating up the bundle while the adhesive is plastic so that the parts so treated are formed intoone unit.

In testimony whereof I affix my signature.
