book between the walls of the device, thus sub- This invention relates to improvements in book protectors and has particular reference to an inexpensive, ornamental, transparent, inconspicious protector adapted to be secured to the book back cover to protect the top, bottom and back thereof from cracking, bending, tearing and premature destruction, ordinarily caused by handling, falls and application of any undue force or pressure thereto.

I am aware of the fact that certain protectors for books have been previously devised,'but these to my knowledge are of the rigid type, embody heavy bosses or shoulders and are applicable only to heavy books; devices that necessarily areincorporated into the books at the time they are bound or rebound, protectors that require fastening elements for securing the same to the.

book backs, thus marring or defacing the book.

My device on the other hand serves to overcome these disadvantages and inconveniences, and being made of a resilient material embodies therein means for enclosing the material of a stituting a firm and resilient support that'will readily withstand and absorb any extraneous pressure, blows and forces. Furthermore, this device not only holds rigid the material of the backs of books, thus preventing wrinkling of the same, which is the principal cause of destruction and tearing of book backs, but also presents a firm, resilient surface to the contact of hands or fingers employed in pulling a book from a shelf. Other objects and advantages will'be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective view of a portionof an open book, showing my .device applied to the book back at the upper end thereof, a section of the back being broken away to illustrate the position of the anchor or elongated portion of the device,

Fig. 2 is a side elevation of a portion of a book, showing the device in section and secured to the top and, likewise, illustrating the device in elevation as secured to the bottom of the book, the view being illustrated on anenlarged scale and is a verticaltransverse section on the line 22v tion of the book being illustrated ini'dot and dash li I 2.

The protector per se, as'disclosed to'advantage in Fig. 3 is formed from a single blank of celluloicl that is sufiiciently hard and yet resilient 5 that will present a sliding surface and effectively save the book back and prevent the same from wrinkling and cracking, etc., as herein before recited.

The said protector embodies in its construction, an elongated body 5 bent upon itself as at 6 and terminates at its upper end in a lip or extension 7 spaced from the body 5 and lying substantially in parallelism therewith throughout the greater portion of its length. 'It will be noted that there is a slight curvature imparted to the body and lip whereby the device more readily conforms to the curvature of the book back and assures a snug fitof the protector on said book back.

In applying the device to the book 7 the elongated body 5 is first inserted between the'back of the leaves 8 and inner side 9 of the cover. The lip 7 will then cover the top and a portion of the outer cover of the book back. To secure the protector to the book, cement as indicated by the numeral 10, glue or any other adhesive material, may be employed, although it is obvious that due to the formation of the lip with relation to the body, any extraneous adhesive medium may be 30 dispensed with and the device will frictionally engage the book back without danger of accidental displacement.

In Fig. 2 I have illustrated to advantage'the application of the device both to the-top and bottom of the hook, whereby the said parts may both be efficiently protected.

While I have specified celluloid as the preferred material, nevertheless-itis obvious th'atmetal having a resilient characteristic, stiffened cloth, stiff cardboard, fibre or similar material maybe readily utilized.

From the foregoingdescriptio-n, considered in connection with the accompanying drawing, it will be obviousthat I have devised a simple, inexpensive, readily attachable and unique book protector that, due to the transparent material. employed, will not obscure the material ofthe book back from view, nor detract from its appearance.

It is to be understood that the form' of my, invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts maybe resorted to without departing from the spirit of the invention or the scope of the. subjoined claims.

Having thus described my invention, I claim:-

1. A book back protector formed from a single blank of material adapted to be secured to the back of a book, said protector embodying in its construction an elongated body member adapted to be inserted between the back of the leaves of the book and the inner side of the back cover, and means formed integral with said blank for covering the top and outer portion of the cover and book back. 7

2. A book back protector formed from a single blank of material adapted to be secured to the back of a book, said protector embodying in its construction an elongated body member adapted to be inserted between the back of the leaves of the book and the inner side of the back cover, means formed integral with said blank for covering the top and outer portion of the cover and book back, said means comprising a lip. formed by bending a portion of the blank upon itself. H

3. A book'back protector formed from a single blank of transparent material adapted to be secured to the back of a book, said protector conforming to the curvature of the book back and embodying in its construction an elongated body member adapted to be inserted between the back of the leaves of the book and inner side of the book cover, and a lip formed by bending a portion of the body upon itself and serving to cover the top and a portion of the outer cover of the book.

4. A book backprotector formed from a single blankof transparent material adapted to be secured to the back of a book, said protector conforming to the curvature of the book back and embodying in its construction an elongated body member adapted to be inserted between the back of the leaves of the book and inner side of the book cover, and a lip formed by bending a portion of the body upon itself and serving to cover the top and a portion of the outer cover of the book,

and means for adhesively securing the protector 20
