Booxrronnnn 53 of a book holder which 'is particularly adapted, although not necessarily, for associationv with a chair to hold a book in convenient position for reading by the person occupying the chair, our invention being further char-' mi acterized by its adaptability to the arm of a chair in such manner that when not in use 1t may be stored within the chair arm and thus completely concealed from view.
Itis also a purpose of our invention to provide a book holder which is characterized by its structural simplicity, ease of operation, and adaptability to securely hold a book supported thereon at any level, distance, and
angle to suit the particular requirements of f a person occupying the chair with whlch the book holder is associated. c
We will describe only one form of book holder embodying our invention and will then( point out the novel features in claims.
In the j accompanying drawings Figure 1 is a view showing in side elevation one form of book holder embodying our invention in stored position within the arm of a chair, the latter being shown in fragmen- Fig. 2 is aview similar to Fig. 1 showing the book holderextended from the chair arm and in book-supporting position;

Fig.l10 is a sectional view line 10-10 of Figure 5; and

In carrying out our invention, we provide a base frame F comprising upper and lower parts 15 and `16 and an intermediate part 17,
taken on the the latter connecting the former, and the4 former kbeing provided'v with vertically aligned .openings 18 in which is slidably received a vpost P. The vertical'portion 17 of the frame F may have Vscrews 19 extended therethrough as shown in Fig.'` 2 for'securing4 the latter to a support. This support in the present instance comprises 4the/arm and leg portion of a chairyand," as shown in Figs. lV and 2, such` portion is hollow in'order that the entire frame may be extended thereinto and secured in proper position to support the post in upright position. *The postis' circular in cross-section to have free vertical sliding'movement within the parts 15 andV 16 of the frame, the `postin its upward `movement being limited by a transverse pin 20 extended through. the lower end of therpost as shown in Fig, 4. `To prevent turning of the postiin the frame in any position `of its vertical adjustment it is formed with a key21 o o-exteny sive in length with the post and vertically movable in suitable extensions of the openings 18fand frame.
The postV P is capable of being latched in vertically adjusted position by the provision of a pawl 22 pivoted on ears 23 of the upper bracketpart 15 and spring-pressed to normally engage the` teeth of a rack 24 formed on upon which a' connecting arm 26 is sup ported and rotatable to occupy any position within a circle. This axle 25 is capable of being latched in any position by means of coacting latch members 26a and 27 on the axle and arm, respectively. The latching member 26a is in the teeth of which are adapted to engage the teeth ofthe member 27 which is in the form of an interrupted miter pinion, preferably cast integral with the arm 26. To ydisengage the two latch members, the member 26a is mounted for movement upwardly on the axle 25 so that it may be manually lifted to cause its teeth to disengage the teeth of the latch member 27. To confine the latch. member 260iy against displacement from the axle, a pin'28 extends through a slot 29 inthe axle 25, with i Vthe pin secured to a collar 30 of the latch memben TheV pin and slot also co-act to prevent rotation of the latch `member on the axley so that when the member 'is in engagement with the member 27 the arm 26 will be locked against rotation in either direction on the axle 25. i Y f The connecting arm 26 is relatively short, but ofl substantial construction for it is designed tol connect the post with v,a rack arm 3 1, while the rack arm in turn supports a rack 32 in which latter the book is adapted to be supported. The rack arm 31 is provided with a head 33 rotatable on a stub axle 34v permanently secured within the arm 26 land detachably associated with the head 33 by `ascrew 34a threaded in the lower end of the'axle and carrying a flange and washer 35 in order toprevent downward displacement ofthe head from the axle. By means of this connection the arm 31 is supported for rota. tion about the axle 34 as a center, andto latch the arm in any adjusted position we provide a pin 36' in the connecting arm 26, and which, as shown in Fig.' 5, has a portion extended `above'the arm which is provided .with a handle 37 Vand another portion extending into a pocket 38/ of the arm and provided with av` head 39 adapted to engage-in any one of a circular series of recesses 40 in the top of the .head 33. The pin 36 is yieldablyurged downwardlyto maintain the head39 within any one recess by meansof a spring 41. Thus, it v will vbe understood that by pulling upwardly onV the handle 37 ,Y the head 39can be elevated free of the recesses 40 to permit turning movement of the head 33, and, consequently,
the arm 31 on the axle 34. Once the circumferential adjustment ofthe arm 31 is effected, the pin 36 can be released,V thus causing the .heady 39 to again engage within a recess 40 to lock the arm in thisy adjusted position.
' The book rack 32 is in the form cfa rectangularplateof metal or other suitable material havingan L-shaped lip 42 at the lower edge,
f. therebetween upon which the lower edgeof thebook is adapted to rest. lAt the rear side form of a miter pinion, the l Yin order to permit the rack justment, we provide latch elements on the rack and arm normally engaging each other' but adapted to be moved to released position to be manually moved to any desired angle. provided with two latch elements 44 in the form of miter pinions fixed to the arm by pins 45. Interposed'miter pinions 46 form the latch elements on the rack 32, and these elements Vare welded or otherwise securedto the rack 32 insuch positions that they coact .with the elements 44 to secure the `rack against rotation on the arm. f
The rack 32 is urged tothe right as when vThe arm 3l is viewed in Fig..4,y so that Vthe latch elements Y 46 normally engage the latch elements 44.- For this purpose we provide a spring' 47l interposed between one of the flanges 43 and a collar 48 at one side of a through the arm 31.V vThis spring 47 is of such tension as to permit the rack 32 to be moved to the left from the position shown in Fior. 4 to that shown in Fig. 7, in Vwhich the elenents 46 are moved free of the elements 44. `With the rack in this position itwill bek evident `that it can be manually-rotated on the arm 31 to assume any angularposition desired. Once the rack is released the spring 47 functions to return it to thenormal position shown in Fig. 4 where the latch elements again function to secure the rack .against movement.
- From the foregoing yconstruction taken'inV conjunction lwith the accompanyingY draw-j it'will be manifest that we have pro-I holder in whichtheV post P al ings, vided a book lows of a vertical adjustment ofthe arm l31 and the rack 32 in order that the rack may occupy any desired ing rotatable on .the ypost P any desired position in orderthat Ithe rack may be positioned'in anydesired horizontal relation with respect to the reader. By an` adjustment of the rack 32 on the arm 31, it can be moved to any desired angle so as to support a book at a corresponding angle, to suit the,
particular requirements of a reader.
In the adaptation of our .invention to a chair, as illustrated in Figs. 1,2, and 3, one leg and arm may be made hollow in order: to provide a compartment K in whi chv the book hold# er is adapted to be received.l This compartment is normally closed by the lid is open access may be had to the' book holderfor extending the post P therefrom to allow thesubsequent adjustment o f'thef'arms 26 and 31, and, if necessary, the adjustment pin 49 extended elevation. The arm y31 becan be lmoved'to.
a lid L,"'and when'l uis lio
of the rack 32 all to the end of adjusting the rack in such manner that a book placed thereon can be positioned and supported at the place and angle most convenient for reading by the occupant of the chair. It is important to note that the connecting arm 26,
being horizontally movable on the axle 25, can be adjusted from the extreme position shown in Fig. 2 to that shown in Fig. 3, and to any intermediate position, all for the purpose of advancing the arm 31 to position the rack 32 in more advance position with respect to the chair so that the book may be supported at a greater distance from the reader than is possible without adjustment of the arm 26. Other important features of 'our invention are the latching members 26a and 27, the mounting of the latching member 26a' permitting a quick release of the connecting arm 26 to allow rapid circumferential ad justment thereof, and a correspondingly quick engagement with the member 27 to secure the arm 26 in adjusted position. Another important feature is the spring-pressed latch pin 36 engaging within the notches or recesses 40 of the head 33. This construction provides a quick release to permit adjustment of the rack arm 31, and a correspondingly quick engagement to secure the arm in adjusted position.
Our invention also embodies a holder H associated with the rack 32 to retain the leaves of an open book supported on the rack against turning. This holder in the present instance comprises a single length of wire bent to provide a U-shaped portionA 50 having terminal extensions 51 disposed laterally and journaled in suitable bearings 52, the latter being secured to the rear side of the rack y32. Knurled handles 53 are provided on the ends of the extensions so as to extend beyond the ends of the rack and either handle may be gripped for rotating the leaf holder to disengage the leaves of the book in order 'to permit turning of the leaves. As shown in Figs. 2 and 3, the intermediate portion 5() is curved upwardly so as to extend around the lower edge of the rack and to engage the leaves of the book on the rack. The leaf holder is held in this position by any suitable means such as the rubber sleeve 54 loosely embracing one of the extensions 51 and urged into frictional engagement therewith by means of a spring 55, all as clearly illus- V trated in Figs. 4 and 6. It will be understood that the spring holds the sleeve against rotation on the extension 51 and urges the sleeve against the extension with a force sufiicient to set up a friction which will yieldabl retain the leaf holder against rotation.
Iii Fig. 8, we have shown another means for securing the post P in vertically adjusted position within the frame F in substitution for the rack 24 and the j awl 22. This means comprises a block 56 slidable horizontally between the frame parts 15 and 16 and urged into engagement with the post P by springs 57 mounted on-pins 58. The block 56 may be formed of wood or any other suitable mae terial which, when pressed against thepost j will function to fric- Y scope ofthe appended claims. 1 j
