ELASTIC BOOKBIN DING.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed January 4, 1918. Serial No. 210,246.

To all whomc't may concern:

Be it known that I, JOHN W. I-IYATT, a citizen of the United States, of 141 Commerce street, Newark, county ofEssex, and State of'New Jersey, have invented certain new and useful Improvements in Elastic Bookbinding, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to provide a means of connecting the leaves of a magazine or book together at the back, which means is especially intended as a substitute for the yielding binding employed in magazines, such as is often formed with metallic fastenings, and by stitching.

The present invention relates to a special application of spiral-springs to perforations extended through the back 'of the book, and also to special means of securing the ends of the springs so that they will hold the book normally closed. and when it is opened they will be extended. 1

The spiral-wire-springs are preferably formed in a series having integral wire-ties, the ties serving to hold all the springs in the perforations, and the extreme ends of the series being secured by special means as hereinafter described. The springs may be used singly, as well as in such integral series, and

.the perforations may be extended straight through the back of the'book, or at an inclination to the face of the book, which permits longer springs to be employed.

Any suitable means may be used for forming the group of spiral-springs with their adjacent ends connected by integral ties, one such means being shown in my copending application No. 210247 filed Jan. 4, 1918, for patent on spring-winding machine.

Thepresent invention will be understood by reference to the annexed drawing, in which Figure lshows the outer side of a book or magazine with the elastic binding applied near its rear edge; Fig. 2 is a section of the book shown in Fig. 1. taken through the centers of the spring-holes; Fig. 3 is a side elevation of six springs connected by integral ties and adapted for use as shown in Fig. 2; Fig. 4 is an end view of the back portion of the book shown in Fig. 2; and Fig. 5 is a modification. Figs. 6 and 7 show different for-ms of the springs, in endviewr Fig. 8 is a perspective view of one corner of the book with the springs secured in the hole by a pin; Fig. 9 shows a book opened and the resulting extension of the springs; Fig. 10 shows a spring disconnected from any of the other springs; Fig. 11 such a spring with thin fiat-heads attached thereto; and Fig. 12 an edgeview of one of the flat-heads suitable for such purpose.

Sloping perforations are preferably employed, and such construction is shown in Figs. 1 and 2, where a designates a group of nine signatures forming a book, the face 6 of which is shown in Fig. 1.

Six sloping perforations 0 are shown extended through the book at alternate inclinations, and a series of springs adapted for insertion in such perforations is shown in Fig. 3, the springs being marked (Z and their integral connectors e. The opposite ends of the series are shown formed with extensions f, but these may be dispensed with and the end of the spring secured by a pin or head, as hereinafter described.

The book is shown in Fig. 2 formed of signatures or groups of leaves, as is customary, and inclined or sloping perforations are readily formed through such signatures by punching holes in the separate signatures at gradually or progressively increasing distances apart, as indicated at g in Fig. 2. Holes in pairs arranged at progressive distances apart form, as shown in Fig. 2, sloping perforations with stepped sides, and the signatures are thus punched with great cheapness bythe automatic punch shown in my application No. 210,248 filed January 4, 1918, and allowed May 31, 1918.

For round springs, such as are shown in Fig. 6, such perforations may be made oval, as shown in Fig. 1, but the coils of the springs may be flattened, as shown in Fig. 7, to facilitate the bending of the springs; and in such case round holes punched in the signatures would produce oval perforations in the line of the spring.

Figs. 1, 2, 4 and 8 show a means of securing the ends of a spring in the perforation by inserting a pin is through and across the coils d at the end of the spring, the end-coil being picked up by the pin and held at the surface of the paper while' the pin ispushed through the-coils, as shown in Fig. 8.

Such spring may be secured from any (lerangement, in the use .of the book, by pasting a tape it over the surface of the book at the spring-holes, thus covering the pins, as shown at h and 7c in Fig. 4, and furnishing a suitable means for attaching a cover to the volume by stitchin if desired. It is, however, preferable, where the tapes are applied to a book having the springs connected by integral ties, to paste the tapes upon the outer signatures of the book before the sig natures are punched, and the tapes are thus punched at the same time as the outside signatures, and permit the insertion of the springs readily in the perforations, leaving the ties e lyin upon the surface of the tape, which it hol s in place and reinforces its strength, when subjected to any strain by the attachment of a cover.

In such case, the pins would lie on the outside of the tape, as is shown at is in Fig. 1, and would be pressed down flat upon the same by a suitable press or flattening tool.

Owing to the thinness of the tape and paper leaves, the proportions of the parts are necessarily exaggerated in the drawing to show them clearly.

The perforations being formed through the book in any suitable manner, the springs are threadedthrough the same with the ties or connectors e lying upon the surface of the leaves, and the ends of the last springs secured in any of the modes shown herein.

The connection of the springs together in an integral series affords a great advantage in the application of the springs to the holes in the book, and in the securing of the springs when inserted; as it avoids the handling of each spring separately and securing each spring separately in its perforation. It will also be noted that the strain upon the springs is, to a great extent, removed from the fastenings of the end-springs and is transferred to the ties and connectors which lie upon the surface of the leaves.

Separate springs may be used, such as are shown in Figs. 8, 10 and 11, which are adapt ed for insertion through the book at right ngles to its surface, Fig. 10 indicating such a spring cl of suitable length to barely extend through the book.

Fig. 11 shows the same spring, with dot ted lines a"indicating the sheets to be bound,

and thin fiat-heads 2' attached to the opposite ends of the springs and bearing upon the surface of the sheets and secured firmly to the springs by the use of a roughened or threaded shank j upon the inner side of the head, which shankis proportioned to crowd into the interior of the springs and to be retained therein by the elastic grip of its coils upon the grooves in the shank.

Fig. 5 shows tapes secured upon the outer sides of the leaves before the springs are applied, and the heads 2' thus lie outside of the apes. 1

and the shank held within the ends of the' springs in such position, so as to press the leaves of the book permanently together.

The connection of the several spiralsprings in each binding, by means of integral connectors or wire-ties, avoids the use of fastenings at both ends, which involve expense and labor to apply, and such fastenings are more prominent than the integral wire-ties which lie close upon the surface'of the leaves, and presents no projections to make their presence objectionable.

It will be observed that the inclination; of the perforations through the book is readily produced by punching the holes in the separate signatures at progressively increasing distances, and uniting the signatures in a volume in the required order to produce the inclined perforations desired.

Having thus set forth the nature of the invention what is claimed herein is:

l. A book having aplurality of perforations next to the back, and a series of spirals springs inserted in the perforations and having integral wire-connectors between the ends of the springs, as and for the purpose set forth.
