HARRISON ANDER-SON, F LOS ANGELES, CALIFORNIA IBOOKHOLDER Application le. June 15, 1929. Serial No. 371,275.

My invention relates to bookliolders, and in open position on the top of the desk, as it has for a purpose the provision of a bookillustrated in Fig. 2, and when not in use in holder particularly adapted for holding a closed position at one side of the desk as book upon or in close proximity to a desk illustrated in Figs. land 5. is illustrated to or other horizontal support and in vclosed advantage in Figs. 2 and 3, a support 15 of 55 and open positions, the holder in its assowood or other suitable material is secured by ciation with a desk functioning to support screws 16 or in any other suitable manner the book in open position on top of the desk, to the side of a desk indicated at 17, the supand when not in use in closed position at one port being cti-extensive in height with the side of the desk. desk so that its lower end is in contact with 60 It is also a purpose of my invent-ion to prothe floor, while its upper end is flush with the vide a bookholder having a book holding top of the desk.

These slots 33 and 34 the bookholder in lowered and folded posiare disposed at right angles to each other so tion. that by loosening the bolts, longitudinal and In carrying out my invention, l provide a lateral adjustment of the plates on the hinge bookholder which is more particularly adapt-A members may be effected in addition to the ed for association with a desk or similar form longitudinal adjust-ment of the plates themof oliice furniture for the holding of a book selves. l

From the foregoing construction, it Will be clear that the hinge members 27 and 28 support the bottom leaf 18 on the support 15 to allow the leaf to occupy the lower position shown in Fig. or the elevated position shown in Fig. 2, while the hinge members 30 and 81 permit swinging movement of the back leaf 19 in respect to the bottom leaf 18 in order to allow the frame to occupy open and closed positions. rlhe hinge members 27 and 28 are disposed one above the other in order to support the book holding frame in a position inclined with respect to the horizontal so that when the frame is in the elevated position illustrated in Figs. 2 and 8, a book supported on the frame will be inclined to facilitate reading.

The bottom leaf 18 is supported in elevated position by means of an arm consisting of two parts hingedly connected to each other and to the bottom leaf and support 15. The parts of the arm are adapted to be releasably retained in longitudinally aligned position by means of a spring 8G and, by the provision of a lever 87, the arm may be broken to allow folding of the parts to permit movement of the bottom leaf to lowered position. The construction of the arm 85 forms no part of the present invention as it is embodied in my Patent No. 1,842,954, dated January 26, 1982.

For retaining a book within the holding frame and securely to the back leaf 191, and in such manner as to permit `-he ready attachment and detachment thereof, l provide flanges 88 and upon the opposite ends of the back leaf 19. These flanges may be formed by extending and bending the ends of the back leaf, as will be understood. The lower flange 89 is provided at its -inner side with a set of relatively pointed prongs 40 which are adapted to be extended between the leaves of a book. The upper flange 88 is recessed as indicated at 41 to accommodate a part of a bracket L12 provided with a head 48 disposed at the inner side of the flange and having a set of prongs Llei thereon which are adapted to extend between the leaves of a book and to co-operate with the other set of prongs s() for securing the book within the frame and against the back leaf 19. The bracket i2 is removable from the flange 88 in order to permit application and removal of a book to and from the back leaf. For securing the bracket in fixed position on the flange 88, I provide a cam lever 5 pivoted on the bracket so as to be movable to engage or disengage the flange 88 and when in engagement therewith to exert an outward pull on the bracket for maintaining the head 48 contiguous with the inner side of the flange 88. TWhen the lever l5 is moved to a position in which its cams are free of the flange 88, it will be understood that the bracket together with its prongs can be readily disengaged from the flange to allow removal of the book from the frame. To prevent twisting movement of the head 48, the upper edge of the flange 88 is lipped as indicated at 88".

In the lowered position of the book holding frame, the bottom leaf 18 abuts a yoke e6 secured to the support 15 in order that the frame may occupy a vertical position and to relieve the hinge members of any undue stress or strain. ln moving the frame to lowered position, which movement may be effected by a folding of the arm the leaf 18 engages a spring L.i7 secured to the support 15 so that if the leaf is accidentally released and the frame as a consequence dropped, the spring will function as a cushion to retard downward movement of the frame and thus prevent the leaf 18 from striking the yoke 16, with a force suiiieient to damage the parts of the holder.

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

l claim:

1. A bookholder, comprising a book holding frame having a bottom leaf and a back leaf hingedly connected to occupy open and closedL positions, means for so mounting the frame on a desk that when said leaves are in open position the bottom leaf can project to one side of the. desk while the back leaf reposes on the desk and co-acts with the bottom leaf to support an opened book in a position for reading by an occupant of the desk, and when in closed position said leaves can be moved to occupy vertical positions at one side of the desk, and foldable means for supporting the bottom leaf horizontally when in open position.

Q'. A bookholder comprising a support adapted to be secured to a desk, a book holding frame, hinged members secured to the support and to the frame so as to permit the frame to be movable to occupy a lowered position at one side Of the support and an elevated position above the support, said frame having bottoni and back leaves movable to occupy open and closed positions, means for detachably securing a book within the frame, and foldable means for supporting the frame in elevated position, the back leaf being disposed to overlie and rest upon the desk when the leaves occupy open position and the frame occupies elevated position.

8. In a bookholder, a frame having a back leaf, two sets of prongs on the back leaf one of which is removable, and means for securing said removable set of prongs to the back leaf so as to coact with the other set in detachably securing a book to the back leaf, said means including a cam manually operable to engage the back leaf and secure the corresponding setfof prongs against removal from the back lea 4f. A bookliolder, comprising a frame having parts relatively movable to permit opening and closing of the frame, means secured to the frame for supporting the latter so that it is movable to occupy elevated and lowered positions, and resilient means interposed in the path of movement of the frame for cushioning movement of the latter to lowered position, said resilient means comprising leaf springs, and a yoke for deiining the lowered position of the frame, said springs being interposed between the frame and the yoke and adjacent the yoke.
