To all whom z' may concern.'

Be it known that I, ARTHUR D. DAYTON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented' certain new and useful Improvements in Processes of Bookbinding, of which the following is a specification.

This invention relates to a novel process for binding `the signatures or sectionsof a book together and has for its primary object to provide novel means whereby the entire book can be handled as a unit during the binding process instead of handling each signature or section independently.

Another object of the invention is to provide a novel book binding process which will simplify the art of book binding and effectively decrease the cost and time of making a book and the necessity of employing complicated machinery for making and uniting the sections or signatures. Y

A further object of the invention is the provision of novel means for uniting the sections or signatures of a book together, which consists in aligning the sections or signatures together and forming diagonally extending slits in the back of the book unit for receiving binding threadsy or cords in counterdistinction to forming incisions straight across the back of the book for receiving the cords, the diagonal incisions with the binding cords permitting the book to be easily rounded and backed and allowing the strain on the threads or cords to be diffused over a large area of the book back thereby allowing the book Ato be opened easily and without disclosing to view unsightly holes. l

A further object ofthe invention is the provision of novel means for anchoring the binding cords or threads in the incisions and the connection of the signatures ori, sections together by a special adhesive and novel means for holding the terminals ofV the threads or cords in place.

i` A further object of the invention is tov provide novel means for securing the end sheets or fly leaves in place for insuring the proper anchoring of the terminals of the binding cords or threads in place and the proper connection of the book unit or signatures with the book back.

A further object of the invention is to provide a book which will be' sifrnplel and easy to manufacture, ons that will dura@ l the same ble and efficient in use, and one which can be placed upon the market at a reasonable cost.

'With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated `in the accompanying drawings, in which drawings,

Figure l is a front elevation of a book section illustrating the various steps in the binding process,

Figure 2 is a rear elevation of the book unit showing the various steps in binding process,

Figure 3 is a transverse section through the book unit taken on the line 3-3 of Figure 1 looking in the direction of the arrows showing the book sections or signatures bound together and the method of applying the end sections or fly kleaves in Place l Figure 4 is a side elevation of the book showing the signatures or sections united and the book unit placed in a book back, the back being shown'broken away and in section,

Figure is a rear elevation of thev complete book showing the back thereof .broken away to illustrate the sectionsor signatures in their complete bound condition,

Figure 6 is aldetail section taken through the complete book taken on the line 6-6 of Figure l looking in the direction of the arrows.

lReferring` to the drawings in detail, wherein similar reference characters designate corresponding parts throughoutv tlie several views the letter A generally -indicates a hook constructed in accordance with my improved process. The book A includes a plurality of book sections or signatures 10 which are bound together in accordance with my invention, which will now be described, to form a lcomplete book unit after which is applied to a conventional cover 1l.

The improved method or processof constructing the book permits allof the sections or signaturesy t0 be handled as a single unit, eliminating the necessity of handling the sections or signatures separately.

In carrying out the invention all of the book sections or signatures 10 are placed one upon the other in proper sequence and lined np byy any suitable means auch as icc 5. The method of forming a book which consists in taking a plurality of book signatures and aligning the same together `to form a book section having diagonally eX- tending kerfs across the back of the book section at an angle to the ends of the book section, applying a coat of adhesive to the back of the book section placing binding cords in the kerfs, applying asecond coat of adhesive to the back of the book and in said kerfs, drawing the terminals of the cords down the sides of the book and securing the same in place by an adhesive, applying end sections to the main book section which consists in a vsingle sheet and a double sheet connected by binding cloth.

6. A book including a plurality of book signatures having kerfs extending diagonally across `the backthereof and binding cords anchored in said kerfs.

7. A book including a plurality of signatures placed together in proper alignment having kerfs extending diagonally across the saine at the back thereof, said kerfs said signatures in parallel relation to the backs of said signatures.

8. In a book including a plurality of signatures disposed in proper alignment having a plurality of equi-distantly spaced kerfs extending diagonally across the back thereof, cords anchored in said kerfs having the terminals thereof anchored to the sides of the book section formed bysaid signatures in parallel relation to the rear edges thereof and end sections disposed over said cord terminals including an inner sheet and an outer folded sheet and a binding cloth secured about the folded edge of the folded sheet and secured to the outer face of the single sheet at the rear edgethereof.

In testimony whereof I affix my signature.

ARTHUR D. DAYTON.
