2 Claims.

This invention relates to a book and particu- 1arly to book constructions, the individual sheets whereof are independent of each other but bound together to form a book. The book when open Will 1ie absolutely fiat and the individual pages thereof Will be accessible substantially from edge to edge. The amount of material a1ong the bound edge which is utilized for associating the pages in their book formation need not exceed a quarter of an inch and preferably approximately threesixteenths of an inch, but nevertheless securely uniting the sheets into book formation. This invention is particularly useful in connection With binding together catalogs circulars, and photop1ints of printed or written matter, which are usually printed upon fair1y heavy paper and often bear printed or illustrative matter c1ose t the binding edges. It may also be utilized in connection With blank books which are provided for keeping memoranda or records, particularly entry books which are ru1ed fro-m edge to edge.

The pages comprising the book are individual sheets but united by the binding element, which binding element, although permanently united with the pages, is, nevertheless, independently movable as the book is opened or closed, reducing the friction at the points where the sheets and the bind.er unite, thereby -preserving the pages against tearing. The book as a whole is flexible and the binding element readily fiexes with the book, particularly in a lengthwise direction, but readily resumes its normal position by reason of its special features of construction.

The binder of this invention is exceedingly strong and not readily deformable permanently during the ordinary use of the book and. the entire binder, if fiexed, Will readily return to its normal shape, tending to support the book as a stiffening element and not being subject to permanent deformation by use in handling and when the book stands on edge.

In the drawing, Fig. 1 represents a book comprising a multiplicity of sheets bound together with the binder element of this invention; Fig. 2 is a cross section on the 1ine 22 of Fig. 4; Fig. 3 is a side view of a portion of the book and. binder from the left of Fig. l; Fig. 4 is an enlarged view from the top of Fig. l; Fig. 5 is an enlarged view of one of the page-supporting elements and portions of the diverging tie rods; Fig. 6 is a section 011 the 1ine 6-6 of Fig. 2.

A bound book comprises a multiplicity of pages i, -provided with holes 2 along the binding edge of the book. The holes 2 may be of any desired shape preferably rectangular or oval. The binder 3 is associated. With the book by threading the pages into the page-supporting elements cf the binder. The binder 3 comprises a multiplicity of fastener elements 4, spaced apart a suitable distance and united With the tie rods 5. Each fastener element 4 consists of two members 6 and l, f0rmed 011 the are of a circle, fiat from the point 8 of divergence, from the tie rod, to the tip 9 of the fastener members 6 and 7. The free ends of each pair of fastener members 6 and 1 are joined by the tip or nose 9, which, at its extreme end l0 is rounded and. narrower than the distance across the fastener members 6 and l. Each pair cf fastener members, as illustrated in Figs. 5 and 6, has the appearance of being made of a single length of fiat stock but actually the fastener members comprise two separate sections of materia1 lying quite close1y together. It is preferred to have the inside edges of the two members 6 and. 7 in contact, but there is a tendency for these members t0 separate slightly in use. The fastening elements do not comprise a complete circle but, to the contrary, extend only from the point 8 to the b-ase of the tip 9. The fastening elements 6 and l terminate at the point of divergence 8 and adjoining fastening members are united together by the tie rods 5 comprising a single course of metal, round in cross section, as shown at l! in Fig. 2. If desired, the tie rods may be bent in a slight are, as shown in Fig. 5, to provide a space I2 which permits the tip 9 to be brought quite close to the surface 015 the tie rods, as is illustrated in Fig. 5.

The individual pages of the book are threaded over the rounded tip 9 and ultimatelj over the body of the fastener members 6, l. This may be done Whi1e the tip 9 is spaced some distance from the tie rods 5 and thereafter the fastener element is deformed to bring the tip 9 in close relation t0 the tie rods.

The binders are preferably made initially of round wire and after the elements are formed but while still in the fiat condition, the fastener elements 6 and l are flattened either by a pinching or stamping operation on an anvi1 or by other suitable tools. The flattening operation is so sonducted that neither the tie rods 5 nor the tip 9 are flattened. During the course of the fiattening operation the otherwise slightly flexible and readi1y bendable Wire is compacted and strengthened.

I claim:

1. A book -comprising a multiplicity of pages having a series of holes along the binding edge thereof, a binder, said binder being made of a, single length of continuous metal formed to promembers of the binder passing through said holes in seid pages'.

2. A book according 120 elaim 1v in which the nose of the binding element is narrower than the distance across the flattened portions of the duplex ringlike members and the tie rode associated, With each flattened portion, diverging in opposite directions from the fiattened portions and forming a space for the entry of the extreme end of said nose to secure the pages 0f the book 10 from escape from said binder.
