BOOK OR BINDER Filed July 22, 1932 Haber! Aabariz 1N VENTOR Patented Dec. 6, 1932 UNITED STATES PATENT OFFICE .HUBERI AUBURN, OF MOUNT HEALTHY, OHIO BOOK OR BINDER This invention relates to book construction, and though it is particularly desirable in its application to loose leaf binders, may nevertheless be embodied in permanent bind- 5 ers of large proportions.

An object of the invention is to provide a novel, durable, and highly desirable hinge connection between a books cover or panel and its back portion.

Another object is to provide a hinge connection such as is above referred to, wherein are eliminated stresses and strains which heretofore have been responsible for the loosening of the covering material from the back'and the panels, and defacing of the binding area.

A further object is to provide aprotected hinge structure for a-book, which is simple of construction and inexpensive of manufacture.

These and otherobjects are attained by the means described herein and disclosed in the accompanying drawing, in which Fig. 1 is a plan view of a'book or binder of the invention.

Fig. 2 is a cross sectionalisometric view taken on line '22 of Fig. 1.

Fig. 3.is a view similar to Fig. '2, show- 30 ingthe book in partly open condition.

Fig.4 is a fragmental perspective view of a back plate cover forming a detail of the invention.

Fig. 5 is a 'fragmenta-l perspective view 35 showing the binder with'the back plate cover removed. 7

The book or binder of this invention preferably comprises a pair of panel-like cover members, one of which is indicated at 6, these cover members being hingedly mounted upon a substantially flat back plate 7 by means of the hinge pin 8. The hinge pin passes through the hinge eyes 9 and 10, which are formed along an edge of the cover 6 and the longitudinal side edges of the back plate, respectively. 7

By means of a bridge 12 or other suitable spacing device, a back cover plate 13 is sup ported in spaced relation'to the back plate 7, so that a space is formed between the back plate 7 and the back plate cover 13. Said spaceis adapted to receive therein a sliding edge or tongue 16, which is carried by the cover 6 and so arranged that it will advance through the space when the back is opened, and be retracted when the back is closed. This sliding tongue covers entirely the hinge eyes and prevents their scratching the table or surface upon which the book is placed when in use. The advantage of having the tongue to enter between the back plate and the back plate cover, is to prevent buckling in that region, and consequent loosening of the covering material in the region of the hinge members. A further advantage is that it renders the binder capable of easy assembly in the manufacture thereof.

In a preferred form of the structure, the cover 6 is made up of suitable layers 14: of filler material from which extends the metallic hinge part 15 which supports the hinge eyes 9, this part being securely anchored in the body of the cover either by means of an adhesive or by means of suitable mechanical fasteners. The cover may be provided with an appropriate inner covering 160, and suitable exterior covering 17 which is glued or otherwise secured to the filler material 14. In order that the cover may be moved about the hinge pin '8 to an extent approximating one hundred fifty degrees (150), the filler material may be tapered or chamfered,-as indicated at 18. The covering 17 follows the chainfer and is secured thereto and to a strip 19 of fabric or the like which is of a flexible nature, the fabric and the portion 16 of the sliding tongue being preferably glued together so as to move over the hinge eyes together. It is to be noted that the free edge 20 of the tongue extends well within the space 15 when the cover 6 is perpendicular to a the back plate 7, and that the free end 21 of the flexible fabric strip extends inwardly to a greater extent, so as to be capable of being anchored between the back plate 7 and the flat portion 23 of the bridge member, as indicated in Fig. 3. The reason for thus anchoring the flexible tongue retaining element is to preclude actual removal of the sliding tongue from the passage or way 15, although it is to be clearly understood that the debridge member is adapted to abut the edges 21 of the flexible retaining element, the lugs 24 thereof being adapted to enter perforations 25 therein and-extend through apertures 26 provided in the back plate 7. The lugs 24 are adapted to be clinched over, as indicated in Fig. 3, for holding the face23 of the bridge member in abutment upon the back plate. The bridge member may be spot welded or otherwise secured to the back plate cover 13, as indicated at 27. At 28 is indicated a series of cross stitches which may be employed, if desired to connect the edge portions 21 of the flexible retaining element. The

characters

29 and 30 indicate layers of covering material which are applied to the rigid back plate cover 13 which member 13 ,may be constituted of metal,. bakelite, orother suitable stiff material.

The back plate 7 also is preferably constructed of rigidmaterial'so that the back of the book may retain a given shape and assure maintenance of the longitudinal aperture or way 15 formed by the longitudinal edges of the back plate and theback plate cover. 1 Y

The arcuate outwardly turned end 31 o member 7 may abut and clamp the covering material 29 against therigid back plate cover 13.

Asstated before, stitchings 28may be dispensed with, and in fact the flexible retaining element 19 could be dispensed with entirely, to render less expensivethe-manufacture of the device, but I have found itpreferable to at least retain the element 19 and anchor it upon the back plate or any other stationary part of the back plate assembly. Inasmuch as the provision of rings or sheet holding bars forms no essential part of the present invention, it is considered sufficient to state that the back plate 7 is adapted to support sheet holding bars such, for example, as are disclosed in .my copending application Serial Number 57 3,911, filed'November 9, 1931; or if desired said back plate may support sheet holding structures of the general character disclosed in the patents of J. Schade 1,478,840, and H. R. McCleary 1,843,608. The present invention eliminates the destructive effects of bending back the covers of the binder to extreme positions, during application thereto of cloth coverings 'be completely finished before application of the back plate cover. Also, the lugs 24'may be caused to make their own openings 25 in the fabric piece 21, (Fig. 5), thereby dispensing with the operation of perforating the fabric. i

It is to beunderstood.that'various modifications and changes in' structural details may be .made,within the scope of the appended claims, without departing from the spirit of the invention. or

WVhat is claimed is; v

11A book comprising in combination a back plate member, a'panel-like cover member, and a hinge connection between said members whereby they may be moved relatively at an angle to one another, a back plate cover secured in a position such as to havean edge thereof spaced from the back plate and the hinge connection, and a sliding tongue fixed relative to the panel-like covermember and disposed over the hinge connection, said tongue being slidable within the space between the hinge connection and the back plate cover. i

2. A book comprising in combination a back plate member, a panel-like cover member, and a hinge connection between said members whereby they may be moved relatively at an angle to one another, a back plate cover secured in a position such as to have an edge thereof spaced from the back plateand the hinge connection, a sliding tongue fixed relative to the panel-like cover memberand disposed over the hinge connection, said tongue being slidable within the space between the hinge connection and the back plate cover, and a flexible tongue retaining ele ment fixed to the tongue and anchored to the back plate member or a part fixed thereto.

3.
