BOOK-HOLDER.

Specification of Letters Patent. Patented N 10, 1914 Application filed August 27, 1913. Serial No. 787,194.

To all whom it may concern Be it known that 1, ERIC R. LUNDIUS, citizen of the United States, residing at Seattle, in the county of King and Stateof Vvashington, have invented a certain new and useful Improvement in Book-Holders, of which the following is aspecification.

My invention relates toimprovements in book holders and particularly to improvements in book-holders of the class described in the United States Patent No. 1,021,614, granted to me March 26, 1912.

The object of my improvements is to provide a simple and eflicient book-holder which may be hinged to a fixed support, as a wall, and which will normally hang vertically adjacent to said wall when the book contained therein is not in use, such book-holder to embody means that may act, when the holder is raised toward a horizontal position, to open a book and to hold the open book at any desired angle while it is being used and, further, to embody means that may act to close such book when the holder is lowered. I accomplish these objects by devices illustrated in the accompanying drawings in which 7 Figure v1 is a view in side elevation of a book-holder embodying my invention. as it appears when secured to a support and when hanging vertically with a closed book heldtherein; Fig. 2 is a bottom plan view of my book-holder in an extended or opened position; Fig. 3 is a view in longitudinal vertical section on broken line y, y of Fig. 2, and Fig. 4 is a view in cross-section on broken line :20, m of Fig. 2, showing certain parts in certain operative positions.

Referring to the drawings in which like reference numerals indicate like parts, 5 is a channel shaped book rest constituting the body portion of my book-holder, 6 is a U shaped supporting member that is pivotally secured to a bracket 7 by means of a pin 8 which passes through the bracket 7 and throughvlugs 9, 9 formed to project backwardlyffrom the'top and bottom ends re spectivelyYof the supporting member 6, thus adapting the supporting member 6 to be swung sidewise.

The book rest 5 has its top end articulated with the top end of the supporting member 6 by a pin 10 and is adapted to swing upwardly and downwardly on said pin 10 to raise or lower a book to any desired angular position.

Wings 11, 11 are mounted to swing in bearings 12, 12 on'the sides of the bookrest 5 and are adapted to engage with and support the sides of a book. The end portion 13 of each of the upper ournals of said wings 11, 11 is extended upwardly through its bearing 12 and then bent to form an angular projection 14 for the purpose of closing the bookholder when such holder rest 15 being formed on each of the bearings 12, 12 to support the wings 11, 11 in their 'is lowered toits' normal position, a stop or open'position and to keep such wings 11,.11

from dropping below the plane of the face of the book-rest -5 when such book-rest '5 is in its extended position. A v I I v The supporting'member '6 is formed intermediate of its length with symmetrically.

curved closing plates 16, 16 whichare spaced apart and project forwardly to' cause their curved inner surfaces to engage with the angular tip portion 14, 'of the wings-11, 11-

to close such wings 11 11, whenthe bookholder is lowered to hang in a' vertical po'-' sition. l

The back surface of the book-rest 5 is formed to have ratchet teeth 17 for a portion of its length and a bracket arm 18 is pivotally secured to the lower portion of the supporting member 6 by a pin 19 and disposed to have its squared topend engage with such ratchet teeth to support the book-rest when the latter is elevated, said bracket 18 having a cross-pin 20 provided adjacent to its outer, end which pin 20 is adapted to,

slide lengthwise of the book-rest between a;

releasing bar 21 and a guide plate 22 and which is provided with a flat spring 23, adjacent to one of its ends, that is adapted to bear against the inside surface of the guide plate 22 normally to keep the pin 20 pressed downwardlyon the releasing bar 21 bracket arm 18 may engage to prevent the book-holder'from being swung downwardly past a vertical position when it is lowered.

A thin flat .bar 26 is provided, for securing a book 27 in the holder, such bar being provided at each of its ends with pins 28, 28 that are normally disposed to project through perforations in the book-rest 5 and thence through elongated perforations 29 in flat springs 30, 30 and to be secured to such springs 30, 30 by. key pins 31, 31 in such manner that the springs will act to draw the bar 26 toward the book-rest 5 securely to hold the book 27, between whose leaves the bar 26 may be disposed.

The releasing bar 21 has one of its sides secured toa side of the bookrest by pins 32, 32 which pins 32, 32 are slightly smaller in diameter than the holes in the sides of the book-rest. 5 through which they pass thus allowing the releasing bar 21 to be tilted to act on that end of the cross-pin 20, that is held by the spring 23, to raise the end of the bracket arm 18 out of engagement with the ratchet teeth 17 and thus permit the book-holder to be lowered.

A flat spring 33 that is provided near the outerend of the book-rest 5 is normally adapted to bear onthe releasing bar 21 to hold it snugly against the lower surface of said book-rest, thus to permit the end of the bracket18 freely to engage with the ratchet teeth, 17, and a pin 3% is secured to the releasing bar 21 adjacent to its free edge, such pin 34. passing upwardly through an elongated hole in the book-rest 5 and terminatingin a push button 35 that is so disposed and arranged above the top surface of the book-rest 5, that pressure exerted on such push button 35 may act to overcome the pressure ofth e spring 33 and thus cause a tilting movement of the releasing bar 21 to raise the end of the bracket 18 above the points of the ratchet teeth and to permit the cross-pin 20 freely to slide on the releasing bar 21 as the book-holder is lowered. A finger hold 36, that is formed integral with the outer end of the book-rest 5 is provided for conveniently engaging the hand with the book-holder in raising or lowering it. v

In Fig. 4, I have shown by a view in vertical crosssection a position that the releasing bar 21 mayassume when the push button 35is depressed, in which position such bar 21 serves to release the end of the bracket 18 from. the ratchet teeth 17 and thus to permit the book-holder to be closed.

a The operation of my book-holder may be described as follows The device is secured to any convenient support as a wall, or a desk, and is normally disposed to hang vertically, adjacent to such support in order that it may occupy but little space. Any book as a directory or dictionary, that is frequently used may be secured to the book-holder by passing the flat bar, 26 between the leaves of the book andsecuring such bar 26 to the springs 30, 30 as shown in Fig. 2 and'Fig. 3, the bookholder then being ready for use. When the book is to be used the finger hold 36 is grasped by the operator and the book-rest is swung upwardly and outwardly on the pivot pin 10 until the end of the bar 18 rides over and engages with the ratchet teeth 17 to hold the book-rest 5 and the book that is supported thereby in a desired angular position, which position may be horizontal as illustrated by solid lines in Fig. 3, or inclined at any convenient angle as illustrated by broken lines in Fig. 3, the angle of inclination of the book-rack being determined by the location of the point of engagement of the bracket 18 with the ratchet teeth 17. When the book-holder is raised the angular projections 14 that are pro vided on the upper ends of the wings 11, 11.

are raised above the curved inner surfaces of the closing members and the wings 11, 11 are thus permitted to swing outwardly into an open position. This permits the book automatically to open at the pages between which the flat bar 26 has been inserted. Such place of opening may be so chosen as most frequently to assist the user in quickly finding the pages desired, as for instance, if the book be a catalogue having an index midway of its pages the bar 26 may be inserted between certain of the in: deX pages, thus when the book is raised for use it will be automatically opened at the index pages to which pages it may most often be desired to refer.

The book-holder may be lowered by grasping the finger hold 36 and pressing on the push button 35 which causes the releas ing bar 21 to assume a tilted position thus releasing the bracket 18 from engagement with the ratchet teeth 17 and permitting the holder to swing downwardly about the pivot 10. As the book-holder is lowered the angular projections 14, that are provided on the upper ends of the wings 11, 11, engage with the curved surfaces of the closing plates 16' and the wings 11, 11 are swung into their closed position thus automatically closing the book.

In cases where it may be desired to have two or more books in the same holder, as where several separate telephone directories are in use, the form and proportions of my holder may be varied to adapt it to meet these requirements, it being only necessary in such instances to construct the book-rest 5 of suflicient width to provide room between the wings for the thickness of the several books to be contained therein, and to provide duplicate holding bars 26 for eachof the books to be used, all of the other details and the mode of operation of the bookholder remaining the same as they are when such holder is designed to be used for a single book.

Manifestly changes in the various details of my book-holder may be resorted to without departing from the spirit of my invention or sacrificing any of its advantages.
