viaooxnonnnn Application led June 15,

My invention relates to bookholders, and it has for a purpose the provision of a bookholder, which in addition to possessing the Vj desirable characteristics of structural sim- 5 plie-ity, durability, and low cost of manufacture, functions to hold a book on a wall or other vertical support either in vertical and closed position against the wall when not in j' use, or in an open and substantially horizon- 'tal position extended from the wall and slightly inclined to facilitate reading.

1t is also a purpose of my invention to provide a bookholder which is more particularly adapted, although not necessarily, for holding telep-hone directories, the holder including a book retaining means which is quickly and easily operable to permit removal and replacement of a directory incident to the changing of directories as is necessary from time to time.

l will describe only one form of bookholder embodying my invention, and will then point out the novel features thereof in claims.

1n the accompanying drawings:

Fig. 1 is a view showing in front elevation and folded, one form of bookholder embodying my invention with a book contained therein.

Fig. 2 is a View showing the bookholder in side elevation and folded, the book being removed.

Fig. 8 is a view showing the bookholder in front elevation and extended with a book open therein for reading.

Fig. 4 is a View showing the bookholder in side elevation and extended.

ln carrying out my invention, l provide a bookholder comprising a wall bracket 15 suitably secured to a wall 16 and having at its O upper end a right angularly disposed lip 17 upon which a book holding frame is mounted to occupy lowered and elevated positions, as

will be clear from a consideration of Figs. 1

and 3. This holding frame comprises a lower leaf 18 in the form of a rectangular plate secured at its upper edge to the lip 17 by hinges 19, the hinge mounting of the lower leaf being such as to permit the frame as a r whole to occupy lowered and elevated posi- 00 tions. This lower leaf 18 is supported in ele- 1929. serial Nc. 371,274.

vated position by means of an arm 20` consisting of two sections pivotally connected to each other and to the bracket 15 and the leaf 18, in the manner clearly illustrated in Fig. 2. rlhe pivotal connection between the arm sections is such that the arm can fold upwardly from the extended position shown in Fig. 8, but not downwardly from such position, so that once it is moved to extended position it operates to retain the leaf 18 in ele- 60 vated position. 1t is important to note that the arm 20 when extended supports the leaf 18 in a slightly inclined position in order that a book supported in theholding frame will occupy a corresponding position to facilitate reading thereof when in the open position illustrated in TEig. 3. A plate 21 pivo-tally supported at the outer end of the arm 2O is manually operable to move the arm to folded position that the leaf 18 may be moved 70 to lowered position. llhe general construction of this arm 2() together with the o-perating plate 21 forms noy part of the present invention but is embodied in my Patent No. 1,842,954, dated January 28, 1932. In an arm of this character, it is moved to extended position with elevation of the leaf 18 so that once the leaf is elevated and released it is supported in elevated position by the arm.

The upper edge of the leaf 18 is bent at 80 right angles to provide a flange 22 which provides a cover for the top of a book contained in the frame, but which is primarily designed to coact with an L-shaped bracket 28 secured on the lower' edge of the leaf 18 85 to support a back leaf or frame section 24. Studs 25 are extended through the flange 22 and the bracket 28 and into lips 26 on the ends of the back leaf 24, such studs providing pivots to swingingly support the back leaf in order that it may occupy open and closed positions on the lower leaf 18. The open position of the back leaf 24 is defined by lugs 27, and it will be noted that in such open position t-he back leaf is slightly inclined. The lower lug 27 is formed on the bracket 23, but the upper lug is formed on a plate 27a secured to the flange 22.

An upper leaf 28 is pivotally supported on the back leaf 24 by a pair of hinges 29 and in 100 such manner that the upper leaf is movable to occupy open and closed positions. The open position of the upper leaf is delined by an elongated plate 30 secured to the back leaf and disposed between the hinges 29. This plate 30 limits opening movement of the leaf 28 in such manner as to relieve the hinges 29 of any strain or stress and to support the leaf in a slightly inclined position to facilitate' are used, and the leaf 28 may be provided with a pencil-holder 34 for writing on the pad.

As illustrated to advantage in Fig. 2, the back leaf 2a is provided with means for de- L tachably securing a book within the book holding frame. This means in the present instance comprises a rod 35 extending through suitable openings in the lips 26, with one end of the rod terminating in a hook 36 while its opposite end is screw-threaded to receive a nut 37, the nut and hook coacting to secure the rod against displacement from the lips. In securing a book within the frame,

,the rod is extended through the lower opening and passed between the leaves of the book, whence its upper end is extended through the upper opening and secured by the nut 37. Vith the rod applied in this manner, the book is securely held against the yback leaf 24 so as to move with such leaf in opening and closing the frame to open and close the book. The book retaining device does not interfere with the free turning of the leaves when the book is in open position.

Vhen the frame is in closed position as illustrated in Fig. 2, the natural tendency of the upper leaf 28 is to swing to open position, particularly under a corresponding tendency of the book. To prevent this action, and thus maintain the frame compactly folded against the wall, I provide a latching device which is operable upon movement of the frame to closed position to engage the leaf Q8 and retain it in closed position. This device comprises a latch lever 38 fulcrumed in a. yoke 39 secured to the further side of the flange 22. A link 40 is pivotally connected tracting action of the link so as to enga'ge the leaf 28 and retain the latter in closed position. In order to permit the necessary freedom of movement of the lever 38, the flange 22 is recessed as indicated at 41.

In the operation of the book holder, it normally occupies the folded position illustrated in Fig. 1 in which the frame is closed about the book and the latter held in upright position against the wall to which the bracket 15 is secured. Accidental swinging of the leaf 28 to open position is prevented by reason of the lever 38. Vhen using the book, the lower leaf 18 is lifted until the supporting arm 20 is fully extended, when, by releasing the leaf the weight of the frame and book operate to maintain the arm extended. The book may now be opened by swinging the upper leaf 28 to the left, as illustrated in Fig. 3. It will be noted that when elevating the frame, the link 40 operates to extend the lever 38 to permit movement of the leaf 28 to open position. In the open position of the leaf, the book is opened and access to its pages may now be had. When returning the v holder to a folded position, the leaf 28 is returned to the position shown in Figure 1, and by merely pressing downward upon the outer end of the plate 2l the joint of the arm 2O may be broken and the arm folded to the position shown in Figure 2.

Although I have herein shown and described only7 one form of bookholder embodying my invention, it is to be understood that various changes and modieations may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim:

1. A bookliolder comprising a wall bracket, a book holding frame including a lower leaf hingedly supported on the bracket to occupy lowered and elevated position, a back leaf pivoted on the lower leaf to occupy open and closed positions, an upper leaf hingedly supported on the back leaf to occupy open and closed positions, lugs on the back leaf, for defining the open position of the upper leaf, and lugs on the lower leaf delining the open position of the back leaf.

2. In a bookholder, a book holding frame movable to occupy elevated and lowered positions, said frame including a leaf movable to open and closed positions, a latch engageable with the leaf for retaining the leaf in closed position, and means operatively connected to the frame for moving the latch to latching and non-latcliing positions according as the fiaine is moved to lowered and elevated positions.
