I HINGE FOR BOOK COVERS Filed Sept. 6, 1939 v 2 Sheets-Sheet 2 A iiorneys Patented Nov. 12, 1940 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates-to a hinge means for connecting two parts of a book cover together.

The general object of the invention is to provide a hinge to which cover members and leaves of a book may be fastened.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the, accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a view looking toward the front of a device constructed in accordance with this invention.

Figure 2 is a section on line 2-2 of Figure 1.

go Figure 3 is a rear view with parts in section.

Figure 4is a section on line 4--4 of Figure 3.

Figure 5 is a perspective view of the rear member.

Figure 6 is a perspective view of one of the g5 hinge members.

In these drawings, the numeral l indicates the rear member which has its top rounded, as shown at 2, and a longitudinally extending groove 3 is formed in the under edge of the member adja- 30 cent, the front face thereof for receiving portions of the back member 4 of the book or cover, the parts being connected together by glue or in any other suitable manner. The under or outer face of the member 4 forms a: continuation of the 35 lower or under edge of the member I, as shown in Figure 2. Notches 5 are formed in the upper portion of the member I and are spaced apart and said notches extend through the upper edge 2 and through the front and rear faces and substantially cylindrical parts 6 of hinges I fit in said notches. Each cylindrical part is formed with a hole 8 and holes 9 are formed in the member I and extend inwardly from the ends thereof and intersect the notches. Hinge pins III are passed through the holes 9 and the holes 8 to pivotally connect the leaves of the hinges with the member I. Each leaf is fastened to a top or cover member H such as by means of the nails I! or in any other suitable manner.

50 Holes I! are formed in the member I and pass from the rear face through the front face and these holesare adapted to receive a cord or strip M which around the leaves ll of a book or the like, as shown in Figure 2 and also in Figure 4. Of course, the device can be used as a leaf binder by having suitable means on the member 4 for holding the loose leaves in the usual or any suitable manner. 5 As shown in Figure 2, the member I slopes slightly forwardly and upwardly with its front and rear faces parallel sloped as shown at l6 and this arrangement throws the 'pivotal points Ill slightly forwardly so that the free edge of the 10 cover member H will substantially align with the front edge of the member 4 when the member I l is resting on the member 4.

As will be seen the hinge has but one leaf with a. circular part at one end thereof which is piv- 15 oted to the supporting member.

It will also be seen that a book or leaf holder as shown in the drawings is of attractive design and when made of wood will have many advantages in holding notebooks, regular books, loose leaves and the like as the comparatively heavy v cover member II with the back member 4 will prevent the leaves from curlingand will hold the leaves pressed together and the member 4 will form a firm foundation when one is writing on 5 the leaves in the device and is holding the device on his lap or knee. v

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It" is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

What I claim is: o

A combined backing strip and hinge for use in book binding comprising a backing bar having a bottom side provided with an undercut front edge for fitting over a cover panel, and a 40 top side provided with s transversely rounded and grooved rib extending along the same and forming one member of a hinge, hinge leaves for attachment to a second cover panel and having hinge eyes fitting in said grooves, pintles extending into said rib and through said eyes, saidstrip being-provided. with transverse apertures therein intermediate said sides thereof, and a flexible tie member extending through said apertures for securing book leaves to said strip intermediate said cover panels.
