This invention relates to improvements in book racks.

Objects Among the principal objects which the present invention has in view are: to provide an improved book rack having means whereby book ends constituting a part thereof will be locked against outward movement; to provide means whereby a plurality of books, magazines, leaflets and the like will be supported in upright position and held closely in place between the book ends constituting part of the book rack; to be enabled to move the respective book ends towards each other and to securely support a plurality of books, magazines, leaflets and the like therebetween; to minimize displacement of books, magazines, leaflets and the like between book ends while moving the book rack from place to place; to provide means on the underside of a pair of book ends to permit movement of the same in a direction toward and away from each other; to provide means on the underside of the book rack; to enable the means on the underside of the book ends to engage the means on the underside of the book rack at all times; to secure simplicity of operation and construction; and to obtain other advantages and results as may be brought out in the following description.

Drawing Figure 1 is a longitudinal sectional view of my improved book rack shown as taken on line of Figure 2;

Figure 2 is an end elevation looking from the right end of Figure 1;

Figures 3 and 4 are cross-sectional views shown as taken on lines 33 and 4-4 respectively of Figure 1; and

Figure 5 is a sectional view substantially similar to Figure 4 and showing a slightly different construction.

Description As seen in the drawing, the reference numeral l0 indicates the improved book rack in general as having a base H, a back upright 12 extending upwardly from the base, front wall [3 and side walls l4, M. The front wall and side walls as seen in the several views preferably extend downwardly from the base member a sufficient distance so as not to interfere with the working mechanism on the underside of the said base. The base in the present showing is provided with slot I5 extending throughout the thickness of the said base with a groove IS in the one wall of said slot, said slot l5 and groove l5 extending from adjacent one end of the longitudinal length of the rack to the opposite adjacent end, with the outer ends being completely.

closed as clearly seen in Figure 1. In construction the material used in the manufacture of the book rack may be of any suitable material,.

such as wood, metal or the like. The design as shown is merely for illustrative purposes, as in the manufacture, any suitable design may be employed to suit individual taste. It is preferred that the rack be light in weight and may be placed on a table, desk or any flat surface so as to be easily moved without disturbing any books and the like which may be held thereby.

In carrying out the invention there is mounted to slide on the top of the base II, but slightly above the surface thereof, a pair of book braces or book ends l6, l6 preferably of upright wooden plates or the like and brackets l1, l1 secured thereto or integral therewith. Said brackets in construction preferably provide finger gripping portions l8, 3 whereby in manipulating, or when desiring to move the said book ends [6, It towards or away from each other, the same may be easily accomplished and without the necessity of taking hold of-the tops of the upright plates. About midway down from the tops and centrally of the brackets l1, I! are provided inverted L-shaped metal members l9, l9, one in each of the said brackets, with the one end of each said metal member extending downwardly through the slot l5 of the base II to approximately midway between the bottom of the base H and the bottom of the front and side walls l3 and M respectively. Approximately in the middle of the downwardly projecting ends of the members I9, I9 is provided a laterally disposed projection H! which in practice rides within groove 15'. This will enable the book ends l6, I6 and brackets I1, I! to remain slightly above the upper surface of the base H and in a position so as not to mar or scratch the surface of said board as the respective book ends are moved towards or away from one another. Each said metal member at the bottom thereof is bent to provide a horizontal fiat surface 20 to which may be secured in any suitable manner, such as by riveting or welding, reinforcing strips 21, 2| preferably as extending slightly beyond the end of said flattened surface 20. Said reinforcing strips 2|, 2| at their projecting ends face away a longitudinally disposed comparatively narrow from each other towards the outer ends of the rack I0. The other portions of the metal L- shaped members extend outwardly towards the outer ends of the brackets l1, l1 and are bent adjacent the said outer ends to provide narrow elongated openings or slots 22, 22 in the said brackets. At the bottom each reinforcing strip is provided with a substantially flat metal spring 23 attached at one end thereto by any suitable manner, preferably by screws 24. The screws 24 are screwed, into the reinforcing strips where said strips are held securely to the underside of the horizontal bent portions 20 of the L-shaped members IS. The outer or free ends of the fiat metal springs 23 are curved slightly in an upwardly direction and are resilient with respect to the secured portions. Mounted in said openings or slots 22, 22 of the brackets l1, ll are triggers or pivoted levers 25, 25 which are preferably pivoted as at 26, 2B. Said triggers preferably are of metal and are of less width than the longitudinal width of the said openings, which in practice will permit swinging of the same in either a forward or rearward direction for substantially the width of the openings. Said triggers likewise are vertically disposed with the upper parts thereof beyond their pivotal points being at right angles to the parts extending downwardly through the groove l5. The upper parts terminating between the top of the brackets .11, I! and the finger gripping members l8, [8, thus permitting engagementof the fingers of a person to grasp the gripping members and a finger to press against the triggers when in operation as will hereinafter be described. The lower portions of the triggers extend slightly beyond the reinforcing strips 2|, 2| and are rounded at their lower ends to come in direct engagement with the free end of the fiat metal springs 23, but not in contact with the reinforcing strip 2|.

On the underside the base H at each side of the groove 15 in the present showing, is provided with a pair of longitudinally disposed ratchets 22, with the outer ends imbedded in the walls l4, M. as by a cross-piece 28 transversely of the base and held securely to the said base. It is to be noted at this time that while I have shown two such ratchets 2?, it is well within the scope of my invention that only onesu-ch ratchet may be employed if so desired. Also, for convenience and operation it will be noted that the teeth of the ratchets face oppositely to each other from the middle cross-piece 2B. Said ratchets 21, 2'5 are spaced apart longitudinally a sufficient distance so as to be in alinement with respect to the fiattened base portion 2% of the member 19, the .re inforcing strips 2!, and the fiat metal spring 23 so a to accommodate receiving the curved outer ends of the said spring into the teeth when desiring to move the book ends or braces l5, l5 away from supporting the books, magazines, leaflets and the like 29 or for adding thereto.

In operation and referring to Figure l of .the drawing, there is shown a plurality of books 29 or the like being supported and held securely in upright positien by the book braces or book ends 15. As looking at the left hand side of the book rack it will be seen that the book end is locked in place against movement in either direction by virtue of the fiat spring 23 being snapped into he ratchet teeth. On the right side the spring 23 is disengaged from the ratchet teeth b:,' virtue of the pivoted member 25 having beenpressed towards the outer part of the opening 22. When The middle of said ratchets are held in place the spring is in this position the book end may be released from its supporting position by gripping the finger gripping portion IS and then moved away a sufiicient distance or far enough to add more books, or the like, to those already in place. Immediately upon releasing pressure against the pivoted member 25, the spring due to its resiliency will yield upwardly to again snap into and engage one of the ratchet teeth. In order to securely hold the books or the like in upright position, and against displacement in the event of moving the rack, the book end is pushed inwardly with the spring 23 disengaging and snapping into each succeeding tooth of the ratchet until it cannot be moved any further, as illustrated in the left hand side of Figure l.

The invention is not specifically directed to the construction shown in Figures 1 to 4 inclusive as the same can be equally applied to shelves, cabinets, radios and so forth. To this end there is shown in Figure 5 a slightly modified construction wherein a base or other flat board I I may be provided with a longitudinal slot l5 and which may extend the entire length of the board or a convenient distance depending on the length of the board, shelf, radio, cabinet and so forth. laicunted on the bottom of the said board I l and adjacent one side of th longitudinal slot l5'f is a block 38 preferably extending the length of the board. To this block may 'be secured as by screws 36 a metal strip 32 which projects inward- 1y beyond the inner edge of the block and towards the slot, and then is bent downwardly to provide ratchet teeth 2?" and in alinement with said slot. As in the preferred showing a track is required for keeping the book ends and their brackets l8 spaced upwardly from the surface of the board l l. To this .end the space between the bottom of the board and the metal strip 3| is utilized as a track 33 wherein the downwardly extending L-shaped metal members H)" are bent to form an inwardly directed ledge 34 to ride within said track in the forward and rearward movement of the book ends. Also, the said ledge 3 3 will function to keep the book ends in raised position away from the upper surface of the board 5 I thereby preventing marrlng and otherwise mutilating the surface of the board. The metal strip from its bent portion or ledge then extend downwardly to slightly below the teeth -of the ratchet and then is bent outwardly to form a platform 20''. To the underside of said platform may be attached as by screws 24 the one end of fiat metal springs 23 with the other end of the spring curved upwardly to engage with --the teeth of the ratchet.
