Very olton :it is desired .to lock a ibook, the covers ot" which have ino't a builtin locking,- device. By nieane of the vdevice :olf the present invent-i on any lot `the `ordinary hooks `1n ay be transformed into a looked book by the application of a -very einiple lockingfstigapa1'- ranged to be anchored between the book covers and a `lockingl claino arranged to embrace and holdtogetherthe open :edges off the icovers9 the clamp `having.a editable looking 4connection with the projecting portion fot `the strap. y i

It is often desired to uarrange euch books as `to .permit locking' et the-openedges ot the covers `to prevent unauthorized `insee/etioniotheeoutentsiofthe ibook. AI-leretotore, ae tar as 11am-aware, special looking or clamping devices had to be built in or otherwise permanently embodied 'in the covers of the booki-n `order toperinit locking` thereof. Accordingl to the present inventioinany bookfot the type illustrated maybe `trans'formed into a locked book without niakingiany `changes in the arrangement ofthe bookiand without requiring theqorovisionofspecial elainpingdevices `that are lpern'ianently connected or :if stened to .the coversor `other @arts i of the book.

yfront end of the strap is offset downwardly f strap fitting overV a post 6 that holds the leaves together. Such construction is shown inv Fig. 3, wherein an anchoring strap 11 has its rear Vend' perforated to lit over the post G of the book, the front end of the strap projectingjinto the slot 16 of the locking clamp l5. like Vthe arrangementv of Figs. l and 2.
The locking arrangement of my invent-ion f is alsol adapted to be applied for locking the upper or lower edge of the book. Suc 1 arrangement is shown in Figs. land 5 wherein y an anchoring strap 20, resembling the shape of a rectangular? triangle, is anchored between the rear edges at the lower end of the I kbook and has a loop member 2l projecting in front of the lower edge of the leaf package and is arranged to fit into a locking clamp l5 similar to the 'clamp l5 described above. The lockingclamp may be locked in place by a padlock inserted through the loop 2l. Instead'of a padlock locking connection be tween the loop members 13, any other locking connection may, ofcourse, be used, for instance, the lock may be embodied directly in the 'locking clamp 15.
The locking clamp may be also arranged to be adjustable for Vbooks of different thicknesses, as shown iin Fig. 6, Vthe clamp consistv ing of two parts 25, 26 adapted to lit over the book edges, and telescopic or overlapping portions 27, 28 extending towards and lit-ting into each other, the overlapping portions being provided with slots 29 through which the loop member vof the anchoring strap may be inserted. The slots 429 in the overlapping portions of the upper and lower clamping ymembers, 25 and 26, respectively, are arrangedto register so that the loop member v13 may be inserted therethrough to provide different thicknesses of the clamp.
rlhe invention is susceptible of many other v modilieations that will suggest themselves to those skilled inthe art and it is, accordingly, desired thatA the appended claims be given a broad construction commensurate with the u scope of the invention within the art.
I claim: l. The combination with a book having a pack of leaves and a pair of relatively rigid covers, of a locking device therefor comprising a loose strap anchored between the covers, a loose clamp adapted to tit over and hold together the open edges of the covers, and a locking connection between the strap and the clamp.
2.: The combination with a book having a pack of leaves and a pair of relatively rigid covers clamped to one side of said pack, of a locking device therefor comprising a strap anchored between the covers at the back edges of the sheets .and having a portion projecting in front of the open edges of the leaves, a loose clamp adapted to ht over and hold together the open edges of the covers, and a locking connection between the projectingl portion of the strap and said clamp.
3. The combination with a loose leaf book having a pack of loose leaves and a pair of binder covers having means for clamping said pack of leaves at the back edge thereof, of a locking device therefor comprising a strap anchored between the covers at the back edge of said leaves, a clamp adapted to lit over and hold together the open edges of the covers, said strap having a projecting portion extending in front of the open edges of the leaves, vand a locking connection between .said projecting portion and said clamp.
4. The combination with a book having a pack of sheets, a locking strap bound withy the sheets, a clamp adapted to embrace free edges of said sheets, and means for locking said clamp to said locking strap.
5. The combination with a book having a pack of sheets, an anchoring strap bound with said sheets, an extensible clamp adjustable for dierent thicknesses embracing said sheets at the outer edges thereof, and means for locking said clamp to said strap.
6. The combination with a book having a pack of leaves and a pair of covers, of a locking device comprising a strap anchored hetween the covers, a clamp adapted to engage and hold together the open edges of the covers and a locking connection between the strap and the clamp.
7. The combination with a book having a pack of leaves and a pair of covers therefor, of a locking device comprising` a strap anchored between the covers, a clamp adapted to engage and hold together the open edges of the covers, said clamp being adjustable for various thicknesses, and a locking connection between the strap and the clamp.
In testimony whereof I have hereunto subscribed my name.
