UNITED STATES BOOK COVER Francis John Osuch, Detroit, Mich. Application April 24, 1933, Serial No. 667,521

6 Claims.

The present invention relates to a novel book cover adapted to be applied to a bound volume, such as a directory, or for enclosing loose sheets of paper, and more particularly to a device for supporting a telephone directory by means of index sheets, such as shown in my prior Patent No. 1,900,462, issued March '7, 1933.

The primary object of the present invention is to provide a sturdy and attractive cover that may be readily applied to bound volumes in a manner permitting its use repeatedly on successive edi-l tions. In this connection the invention provides bowed rods, similar to those shown in my prior Patent No. 1,900,462, wherein index sheets are provided with apertured tabs through which the bowed rods extend to secure the sheets .within the cover in which the bowed rods are secured, these index sheets being the means of securing a bound volume within the covers. n order to facilitate easy removal of such bowed rods and to permit the same covers within which they are secured to be applied quickly and easily to another volume, the present invention provides a novel means for securing such bowed rods within the covers, and such means constitutes an improvernent over the above mentioned patent.

With the above and other ends in View the invention consists in matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which- Figure 1 is a plan view of the present cover in an open position;

Fig. 2 is an end View corresponding to Figure 1;

Fig. 3 is a fragmentary cross section taken along the line 3-3 of Figure 1;

Fig. 4 is an enlarged fragmentary plan with parts broken away;

Fig. 5 is a fragmentary side elevation;

Fig. 6 is a perspective view of an angle bracket, and

Fig. 7 is a perspective view of a locking plate.

Like characters of reference are employed throughout to designate corresponding parts.

The present cover comprises a central back piece 1 and sides or flaps 2 hingedly attached to the longitudinal edges thereof, or as illustrated the back and flaps may be constructed as a single integral part that is creased as at 3 to provide the hinge or bending action at the desired point.

The back strip 1 is somewhat wider and longer than the back or binding of a book or volume or a plurality of books or volumes to be received within the covers.

'" To each of the ends of the back strip 1 is secured an angle bracket 4 that extends transversely thereof and is secured thereto by hollow rivets', i the upper ends of the rivets being counter-sunk." as at 6 in counter bores in the upper `surfacefof the bracket so that said upper surface remains smooth. The bracket 4 is formed with an integral finger 7 projecting upwardly from one end theref oi" and bent to lie in a planeparallel to vand spaced from the bracket 4. On the same end of the bracket 4 as the nger 7 is formed an upwardly directed ange 8, and adjacent the other'end is formed another iinger 9 that corresponds in shape, size and spacing to the finger '7. The hol low rivets 5 are located adjacent the ends of the bracket 4 and apertures are formed in the4 fingers 'Z andL 9 and are each directly in line with one of 'the hollow rivets.I

A bowed rod 11 is provided with grooves 12 adjacent its ends and the ends"y of the rod are inserted through the apertures 10 in the fingers 7 and 9 and enter the hollow rivets 5. A guide nger 13 is secured on the bracket`4and serves to hold vthe bowed rod 13 ina position whererthe .grooves 12 are located in the space between ythe ngers 7 and 9 and the bracket 4. The bowed rod ll may be formed of one continuous piece, or it may be formed of two pieces, one having a bore and the other having afpilot portion inserted therein as at 1.4, the objecty in forming it in two parts not being to alter the function thereof but to permit easy insertion of the rod through perforations in a large number of sheets of paper at one time.

A locking plate 15 has one end received beneath the finger '7, and a slot 16 in that end in which the groove 12 on the rod which is located between the nger 7 and bracket 3 as above described is received. Adjacent the other end the locking plate is provided with a keyhole slot 17 that permits the plate to lie flat on the bracket 4 so that the reduced portion of said keyhole slot may receive the groove 12 in the end of the rod that projects through the nger 9. The locking plate 15 is provided with an upturned flange 18 that serves as a nger piece so that pressure may be applied thereto manually to slide the locking plate on the bracket 4 beneath the fingers 7 and 9.

It is obvious that books, sheets, or folders having apertures therein or apertured tabs thereon, may be assembled on the rods 11 which then have their ends inserted through the fingers 'I and 9 so that they enter the rivets 5, with the grooves 12 in the rods located betweeen the fingers and the brackets. The locking plates 15 are then moved soA rtf-

loo

i rods 11 the brackets'fi are provided with depressions or grooves 19 into which the ends of springlike flexible rods 20 are inserted by bending the same. Y

Although a specic embodiment of the present.

invention has been illustrated and described,l it is to be understood that various changes may be made Within the scope of the` appendedclaims, without departing from the spirit of the invention, and such changes are contemplated What I claim is:

1. A vdevice of the character described including a bracket having/spaced apertured members formedk integral therewith, a substantially U- shaped grooved member having its ends inserted vthrough the apertures in said spaced members withl the groovetherein located between said bracket and'said spaced members, and a locking platehaving a keyhole slot surrounding one of said spaced members and slidable beneath the other of said members, said looking plate. having portions received in said grooves and preventing withdrawal of said U-shaped grooved member from said apertures.'

2. A book cover including a back strip, a bracket secured to said back strip, said bracket having an aperture therein, an apertured member spaced from said bracket abovejthe aperture in said bracket, Aa rod extending through said apertured member into the'aperture in said bracket, said rod having a groove disposed between said bracketan'd aperturedmember, and a locking plate having a keyhole slot surrounding said apertured member and facilitating reception of said plate inA the groove in said rod.`

3. A book cover comprising a back strip, brackets secured adjacent the ends of said back strip, each of said brackets having a pair of apertures formed therein, fingers spaced above said brackets and provided withV apertures, said iingers corresponding in number to the apertures in said brackets, rods having grooved ends extending through the apertures in said fingers into the apertures in said brackets, and a locking plate on each bracket, each locking plate having a keyhole slo-t permitting movement thereof between one of said fingers and its respective bracket and entering said groove in the end of said rod which is disposed between said respective. iinger and bracket. v

4. A book cover comprising a back strip, brackets secured adjacent to the ends of said back strip, saidbrackets each having a pair of` apertures therein, a pair of fingers spaced above each of saidl brackets and provided with apertures, a substantially U-shaped rod having grooved ends extending" through said ngers into the apertures in eachk bracket, locking plates, each of said lockingl plates yhaving relieved portions permitting movement thereof between said iingers and their respective brackets and enteringA said grooves in the ends of respective rod's,`said bracketshaving depressions therein, and flexible rods having op" posite ends received insaiddepres'sions in ,opposite brackets.v

5. A book'. cover comprising 'a back 'stripifa' bracket, hollow rivets securing said bracketadjacent to the end of said back strip, iingers spaced above said Ibracket and having apertures in line` a back strip, a pair ics of brackets, hollow rivets securing said brackets adjacent to the ends of said back strip, a pair of fingers spaced above each bracket and having` apertures in vline with said" hollow rivets, a groovedrod inserted'through each pair of said fingers and entering` said'hollow rivets on respective brackets, a'locking plateA 'oneach'bracket having relieved portions permitting movement thereof between each bracket'and its respective lingers to enter said grooves in saidrrods, said brackets' having elongated depressions formed therein', and flexible' rods having their opposite endsreceived in depressions in opposite brackets.
