Description:

This invention relates to book holders, and it is primarily an object of the invention to provide a device of this kind which can be readily and ,conveniently manipulated and which operates , . effectively to support a book in a position to best comply with the convenience of the reader, together with means to maintain the book in open position yet readily permitting the required turning of the leaves.

:;It is also an object of the invention to provide a device of this kind which, when applied, serves to support a book in open position and in a manner to eliminate accidental turning of a page and wherein the construction of the device is such to allow the same to be conveniently used as a book end. . S:,The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved book 20j holder whereby certain important advantages are attained and the device rendered. simpler, less lexpensive and otherwise more convenient and Sadvantageous for use, as will be hereinafter more fully set forth. ...

,The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:SFigure 1 is a view in perspective of the book holder constructed in accordance with an embodiment of my invention unapplied and in an open or extended adjustment; Figure 2 is a view in end elevation of the device as illustrated in Figure 1 applied to a book; Figure 3 is an elevational view and of somewhat a diagrammatic character illustrating the use of my improved holders as herein disclosed -0 as book ends; Figure 4 is a view in end elevation of a holder as herein disclosed applied to a book with the parts in fully folded adjustment; Figure 5 is a view in end elevation illustrating a pair of holders constructed in accordance with my invention applied to a book; Figure 6 is a transverse sectional view taken through the central portion of my improved holder as herein disclosed unapplied and in folded or compacted adjustment.

As disclosed in the accompanying drawings, my improved holder comprises a pair of elongated plates I and 2 of a material possessing the required strength and rigidity, said plates being 65 each of a length to extend at least a major distance across the back covers 3 of an open book.

These plates have their central portions hingedly connected, as at 4, so that said plates I and 2 as particularly illustrated in Figures 3, 4, 5 and 6 can, when desired, be folded into overlying relation.

One of the plates, as 1, has its outer longitudinal marginal portion defined by an outstanding flange 5 relatively broad at its extremities but being reduced toward its center. The central portion 6 of the flange 5 is cut out to allow said flange to readily bridge the back binding of a book when the covers 3 are in extended or open position.

The face of the plate I at the same side thereof as the flange 5 has disposed transversely thereacross but positioned closely adjacent thereto the relatively broad leaf springs 7, each of said springs 7 having an end portion 8 as indicated by broken lines in Figure 1 angularly disposed and welded or otherwise securely attached to the flange 5. These springs 7 are spaced apart lengthwise of the plate or member I and are located to have effective coaction with the open covers 3 of the book, each of said covers being slidably engaged between a spring 7 and the member I. To facilitate the effective contact of a spring 7 with a cover 3, the outer or free end portion of said spring 7 is provided thereacross with a rounded bead 9 disposed toward the member i.

The inner face of the flange 5 at opposite sides of the cut-out portion 6 has adhesively or otherwise securely fixed thereto the pads 10 of porous rubber or kindred material which are adapted to have contact with the edges of the book pages SI and thus effectively hold said pages against accidental turning movement yet readily permitting the reader to turn a page as desired. As clearly illustrated in the accompanying drawings, the upper surface of each of the pads 10 is transversely inclined downwardly toward the plate I to further facilitate the maintenance of the book leaves against accidental turning.

The second plate 2 has its outer longitudinal marginal portion defined from substantially one end to the other by a flange 12 substantially the same as the flange 5 hereinbefore referred to and also provided with the central portion 6' to bridge the back of a book. This flange 12 when the plates I and 2 are in extended or open position is disposed in a direction opposite to the flange 5 but the flange 12 overlies the flange 5 when the plate 2 is swung into closed or compacted position with respect to the plate I as is clearly illustrated in the accompanying drawings.

The outer face of the flange 12 at opposite sides of the central cut-out portion 6' has disposed thereover the laminations 14 of rubber or kindred material and which laminations are extended to overlie the outer edges of said flange 12. These laminations 14 are provided to eliminate scratching or marring of the surface upon which the holder may be rested to support a book or when the compacted device is being used as a book end as illustrated in-Figure 3 of the accompanying drawings.

Each end portion of the member or plate I and the adjacent end portion of the flange 5 at the junction thereof is cut away, as at 15, to snugly, receive and hold a pad 16 of rubber .or'kindred material. This pad or foot 16 projects beyond the corner edge afforded by the member"! and flange 5 for direct contact with the surface-upon which the holder may be placed as is particularly illustrated in Figure 2.

With the plates' -and 2 in the adjustment as illustrated in Figures 1 and 2 the applied book is held upon a surface on an incline as determined by the flange 12 although the desired'angle of the book may be varied by adjusting the plate 2 into different angular positions with respect: to the plate 1. The book may also be supported in substantially a vertical position as illustrated in Figure 4 with the plates I and 2 in folded or compacted adjustment, or the book may be held upon the lap or other locations with the device folded or compacted as illustrated in Figure 4 when it is only particularly desired to use my improved device to hold the book open and the pages II thereof against accidental turning movement.

When a single holder is employed it is preferably engaged with the lower portion of the book or more particularly the covers thereof although it can be employed to advantage if engaged with the upper portion of the book.

Under certain conditions it is also of advantage to apply holders to both the upper and lower portions of a book as illustrated in Figure 5 and when a holder is applied to the upper portion of a book the plate or member 2 may be extended as desired to hold the book upon a surface at substantially a predetermined angle to ,suit the convenience of the reader.

While it is not essential that two of my-improved holders be employed with a book, yet in practice I find it of advantage and probably more satisfactory-to use two holders and by distributing my improved holders as a set of two I also make provision for book ends to which use the device may be put with convenience and facility.

From the foregoing description it is thought to be obvious that a book holder constructed in uo accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts s herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:1. As a new article of manufacture, a pair of elongated plates;, means for hingedly; connecting marginal .portions: of said~ plates to. allow said plates to be disposed one over the other, outstanding flanges carried by the opposite longitudinal margins of the plates, said flanges lapping-when the plates are in folded or compacted adjustment,.and .pads of yielding material carried by the flanges of one of the plates and disposed over the inner faces of said flanges for engagement with the leaves of an applied book to hold said leaves against accidental turning, the top surfaces of: the t.pads being- disposed 'on a transverse. downwardt incline -toward· the adjacent plate.
