UNITED STA CHARLES J. HILKEY, or nns ivronvns, IOWA.

nook-HOLDER AND r nvn enrnn.

To all whom it may concern:

Be it known that I, CHARLEs HILKEY, a

citizen of the United States, anda resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and usefulBook-Holder and Line-Guide, of which the following is a specification.

The object of my invention is to provide a book holder and line guide of simple, durable and inexpensive construction, so arranged that it may be readily and easily ad justed for holding all books of the ordinary size in such position, that the open exposed pages of the bok will lie in substantially the same plane. a

Another object of my invention is to provide a line guide and equalizing device capable of movementand adapted to rest upon the open pages of the book.

More particularly it is my object to provide a book holder, which is provided with a 9 pair of book supporting members, capable of plvotal movement relative to each other, whereby the lower forward ends "of the book supporting members will lie in different horizontal planes. The advantage in providing a book holdercapable of having the book supporting members so arrangedthat the lower forward ends are in different horizontal planes is that the back or binding of the book will be taken care of, thereby permitting the bookto lie absolutely fiat upon the book supporting members. It will be understood that when a book is open and at some point not exactly in the center, that the binding will cause the forward edges of the backsof the book to rest in different horizontal planes. My device is so adapted that it will take care of any such conditions.

Still a further object of my device isv to provide a pair of book supporting members capable of being inclined at various positions and to be lockedin any of its various positions. is r Still another object is to provide in combination with a pair of book supporting members a folder or line guide, capable of movement and yet adapted to be yieldingly held uponthe surface of the'exposed pages. of an open book. I

With these and other objects in view, my invention consistsin the construction, arrangement and combination of the various parts of my device, whereby the objects con templated are attained, as hereinafter more fully set forth, pointed out in my claims, and

Fig. 8 shows a front elevation of my book holder, parts being broken away to better illustrate the construction.

Fig. 4 shows a side elevation of the device, the book supporting members being shown in different planes, and

Fig. 5 shows a central, sectional view taken on line 5+5 of Fig. A, the book sup porting members being shown moved relative-to each other. 1

In the accompanying drawings, I have used the reference numeral 10 toindicate an ordinary base, which may be: of any suitable material, which is provided with the cushion members 11 on its under side.

Rotatably mounted within the base 10 and extending upwardly therefrom is the support 12. The support 12 is provided at its upper end with a squared portion 13, to which is pivoted the yoke member 14 by means of the pintle 15. v I

Fixed to the yoke 14 is the bar 16, which is adapted to receive the frame of the book supporting members.v

On the lower end of the bar 16 and adja cent to one ofits sides is formed the curved bar 17 which is provided with the correthe short braces 21 and 22, to which are pivoted the crossarms 23 and 24. The cr0ss arms 23 and 24.- are each pivoted at their ends to the frame members 25 and 26. The frame members 25 and 26 are each provided with the openings 27 and 28. r

Resting upon the frame members 25 and 26 respectively are the book supporting 1 members 29 and 30. The book supporting members 29 and 30 are locked or fixed to the frame members 25 and 26 by means of screws 31, which are designed to extend through the book supporting members and to be received within the openings 27 and 28 of the frame members.

Fixed to the rear portion of the frame members 25 and 26 and extending outwardly and upwardly therefrom are the reinforcing bars 32 and 33. The reinforcing bars 32 and 33 are secured adjacent to the outer edges of the book supporting member by means of the screws 34.

Fixed on the under side of the bar '16 directly below the short brace 21 is a similar short brace 35.

A cross arm 36 is pivoted to the lower end of the short brace 35, while the outer ends of the cross arm 36 are loosely riveted to the frame members 25 and 26. g

It will be understood that the frame members 25 and 26 are substantially U- shaped with the exception that the rear portion is somewhat longer than the forward arm. Fixed to the frames 25 and 26 are the forwardly extending inclined braces 37 and 38. The forward end of the braces 37 and 38 are secured to the book supporting members 29 and 30.

It will thus be seen that substantially a rigid frame construction is provided for supporting the pair of book supporting members; and yet the construction is so that pivotal movement of the book members is provided for. s

It will be seen that the short braces 21, 22 and 35 act as centers upon which the book supporting member move.

The arms 23, 24 and 36 are all secured at their outer ends to the frame members 25 and 26 by means of loose rivets, which act as pivots whereby the book supporting members may be moved relative to each other.

At the lower forward ends of the book supporting members 29and 30, I have provided an upwardly extending flange 39 and 40, which tend to keep the book from slipping off of the book supporting members, while they are in their inclined position.

From theconstruction of the parts just described, it will be seen that I am able to move the book supporting members relative to each other, whereby their lower forward ends will rest in different horizontal planes. 1 The advantage of this construction is that the book will lie absolutely fiat upon its supports regardless of the point at which the book is open.

The book sup orting members are spaced apart, so that when the book is laid upon them, the binding will come between the two supporting members.

The drawings in Fig. 4 show that the lower forward ends of the book supporting members are in different horizontal planes,

relative to each other. The parts are so arranged that theheavier side of the book will tend to cause one of the book supporting members .to-lower', while the other one will automatically be raised, thereby the open exposed pages in the book are substantially in the same plane. A 6' 5 Near the upperend of the bar 16, I have provided the hinged bearing member A, which comprises two spaced wall members 41 and 42. The wall members 41 and 42 of'the hearing A are spaced apart by the rollers 43. the short shafts 44, which are journaled within the wall members 41 and 42. The bearing A'is hinged to thebar 16, by means of the bolt Aspring *46is provided, which has one end fastened into the hearing member A, and its other end' secured to the bar 16. o

It will thus be seen that the bearing member 'A is being yieldingly drawn forwardly.

Slidably mounted between the upper and lower series of rollers 43 is the rod 47, which is provided with a flattened portion 48 near its lower end.

The lower squared portion 48 of the rod 47 is received between the yoke member 49. The yoke member 49 is securely fixed to the guide or equalizing device 50 by any suitablemeans. The guide .or equalizing device 50 is of comparatively heavy weight material, so that it will tend to cause the opened book to rest evenly upon the book supporting members, the spring 46 causing the guide or equalizing device to be held under tension. 1

The parts of the guide device are so adapted that they maybe swungupon the pivot 45 until they are substantially in the position shown in dotted lines in Fig. 1 of the drawings.

The rollers 43 are mounted on When the guide device is in this position, 7

it will be seen that I am able to place a book of any size upon my book supporting members without the guide device interfering, and yet I am able to have ready and easy access to the guide device, when it is desired to be used.

The rod 47 which .is slidably-received be tween the rollers 43, makes it possible forthe operator to use the guide device 50, as an indicator, for theline of printed matter, which is being copied or read.

The yoke member 49 serves as a handle when it is desired tomove the guide device 50 from one line to another.

In the practical operation ofmy device, the guide device is raised and ,a book then is placed upon the book supporting members. The guide device, which is always held under-tension, is then placed over the open pages of. the book. This will promptly tend by merely operating the bolt 19 and the wing nut 20. It will thus be seen that'I am able to so operate my book holder, that it may be used for a great many different lines of work.

Some changes may be made in the construction and arrangement of my book holder and line guide, without departing from the real purpose and spirit of my in-' vention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
