BOOK-COVER PROTECTOR.

Application 'filed January 13, 1925. Serial No. 2,106.

To all whom it may concern:

Be it known that I, JARRETTE. THOMP- soN, a citizen of the United States of America, residing at Atlanta, county of Fulton, State of Georgia,have invented certain new and useful Improvements in Boole Cover Protectors; and I do hereby declare that the following is a full, clear, concise, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements inbook cover protectors and has for am object to provide a novel and practical, yet

simple form of book cover protector whose arrangement and construction is such as will permit the same to be successfullyemployed as a covering for books of different sizes, being reinforced at the ends and corners and affording a smooth and continuous or =unbroken exposed surface, thereby lending to the periodof practical usage of the same as well as giving absolute protection to the book cover proper.

It is likewise an object ofthe invention to provide a book cover protector having portions of the same, namely, at the corners and centers of the upper and lower ends thereof, cut and forming tongues, which, in turn, are supplied with guide markings whereby to facilitatethe fitting of the pro tector to a book cover, as well as the accu rate folding of such cover protector and tongues during the process of fitting it'over a book cover.

Other objects of theinvention will-be in part obvious, and in part pointed out liere' inafter.

In order that the invention and its mode Figure 4 is an end view ofthat form of,

the cover shown in Figure 3;

Figure 5 1s a fragmentary detail in'plan showing the form .of book cover protector shown'in Figure 3 in folded position;

Figure 6 is a vertical transverse section taken on the line 6-6 of Figure 5;

Figure 7 is a plan view of another modified form of the book cover protector; and

Figure 8 is a corresponding view of'the Having more particular reference to the (ilIttWlIlgSfilIlCl especially in connection with that form of the invention disclosed in the Figures 1 and 2, the "book cover protector may be stated to comprise a sheet of suitable material, generally indicated herein by-the numeral '1, suchas heavy paper, fabric, et cetera.' The sheet or body of the cover protector as shown herein is substantially rectangul-arin shape and has eachof the four corners thereof cut whereby to provide diagonally disposed tongues 2, 3, land 5, the edges of these tongues being preferably formed by straight lines of perforations or reverse side of that protector shown in Figure 7.

accurately". identified and the same may, be

similarly folded when properly measured to a book cover, and in order that other cover protectors may be similarly folded, when covering books exactly the same size, without needing -'to remeasure. The intermediate sideportio-ns of thesheet 1, that is, those portions directly between the inner extremitiesof the tongues 2 and 3 and 4: and 5 are adhesively coated on the face opposite to that on which the lines are ruled, as is indicated by the numeral 9, the purpose of which will be subsequently described.

Other tongues '10 and 11 are provided upon'the top and bottom ends ofthesheet 1, centrally of the same, as is clearly shown in the Figure 1, and as will be noted, are

extended .or disposed transversely ofsaid sheet inopposed fashion. These tongues are formed withcurved edges 12 and such edges may be completely severed from the adjacent portions ofthesheet 1 or 1f desired, curved or curving lines of perforations or of scorings may be substituted in lieu thereof in order that certain portions ofsuch tongues 10 and 11 may be disjoined from thesheet 1, such as conditions or preference may dictate, this depending, as will be understood, uponthe size or depth of the book cover to be protected by the invention. Also, the basal portions of each of thesetongues 10 and 11 are provided with transversely disposed relatively spaced and parallel guide markings or lines generally indicated by thenumeral 13, each of said guide lines or markings being appropriately designated bynumerals 1%, or other suitable nomenclature in order that they may be accurately marked and folded during a fitting of the cover protector to a book cover, and if properly measured to other book covers the same size without remeasuring.

In the Figure 3, I have shown a slightly modified form of book cover protector wherein the top and bottom tongues of thesheet 1 are formed in the following manner; curved portions or cut-outs, such as indicated by thenumeral 15 are formed in the top and bottom central portions of thesheet 1 and there is arranged transversely over the face opposite the ruled lines of said sheet a strip ofmaterial 16 corresponding the first mentioned embodiment of the in-.

vention. By this peculiar arrangement or formation of the tongues which are indicated at this time for the purpose of con venience by thenumerals 10 and 11, it will be understood that the cover will be materially reenforced throughout its area of on gagement with thestrip 16. Therefore, since it has been found through actual ex periment that a book cover protector fre-.

quently gives way first in the center of books covered thereby, thisstrip 16, obviousy, will give double thickness'to the book cover protector, thus lending materially to the strength and durability of the same.

Thisstrip 16 is only attached tosheet 1.

along its center enough to hold'it in place, retaining flexibility.

In using a book cover protector constructed in accordance with those several formsof the invention shown in the Figures 1 and 3, it will be understood that thesheet 1, chosen at this time, for purposes of illustration, is laid upon a supporting surface with the markings upon the various tongues uppermost. An openbook is placed in the center of the cover protector and is pressed open on the cover and held substantially flat in such position whereupon suitable markings are inscribed upon the face portions of the sheet 1., that is, tongues 2 and a and 3 and 5, about one-fourth of an inch from the corners of the book cover, allowing siuiicient to prevent folding corner tongues too short to cover all corners of the book cover. Also, suit-able markings are made upon thetongues 10 and 11 or 10 and 11' as the case may be, in order that the length of the book may be accurately recorded upon the pro tector, allowance being made in these latter markings for a distance of one one-sixteenth of an inch beyond the opposite ends of the book cover in order that the protector will fully cover the same and will have slight portions thereof extended beyond the book ends whereby to best protect the same. lVith thesheet 1 marked in the manner prescribed upon the tongues 2, 3, at and 5 andlO'and 11 or 10 and 11', the book is then removed and the tongues 2 and 4 and 3 and 5 are folded inwardly upon themselves along those particular guide markings or lines 7 adjacent the markings indicating the corners of the book cover. Thetongues 10 and 11 or 10 and 11 are now folded transversely of themselves along the particular guide markings orlines 13 or 13 thereon, the same being turned inwardly of the cover protector, as are the diagonally disposedtongues 2 and 4E and 8 and 5. With the six tongues 2. t, 3 and 5, 10 and 11 or 10 and 11 folded inwardly of thesheet 1, the top and bottom portions of the opposite ends and adjacent portions of saidsheet 1, that is, those portions as between the various corner tongues and thetongues 10 and 11 or 10 and 11' are folded inwardly upon a straight line and over the book cover so as to align approximately flush but slightly beyond the adjacent marginal portions or edges of the book cov r, first refolding corner tongues if necessary. At this time, the intermediate portions of the opposite sides of the book cover protector, that those portions having the adhesively coated extremities 9 are folded upon themselves along a straight line over the outer marg ly folded parts of the sheet 1., that is, those parts that lie between the diagonally disposed tongues and thetongues 10 and 11 or 10 and 11. The adhesively coated extremities 9 are pressed downwardly for a length of time to ensure adhesion between the contacting. portions. In a similar manner, the opposite side of the sheet constituting the llO book cover protector is folded over the opposite side of the book cover, that is, the top and bottom portions between the corner tongues 2 and 4E and theend tongues 10 and 11 or 10. and 11' are folded inwardly upon a straight line and over the book cover and finally, with folding of the intermediate portions of the sheet upon themselves in the manner hereinbefore described, the adhesively coated extremities 9 of the intermediate side portions are then moistened and pressed into permanent engagement with adjacent portions of the folded intermediate top and bottom portions of thesheet 1.

In the Figure 7, have shown yet another modified form of my improved book cover protector, wherein one side, the left side as shown herein, of the cover protector is partially folded and sealed. The upper or top of this particular side of the book cover protector is left open and with proper marking of the graduatedtop tongue 1"? which is then folded inwardly and transversely upon itself in the manner hereinbefore described, said left side of the folded cover protector sheet, indicated for the purpose of convenience by thereference numeral 1 is then folded along a straight line and over the adjacent upper end of the book cover received therein, whereupon an adhesively coatedextremity 18 of theintermediate side piece 19 is moistened and pressed into permanent contact with the adj acent part of such folded portion.

The opposite or remaining and right side of thissheet 1 is formed with diagonally disposed tongues 3 and 5' havin ruled transversely thereof a plurality of relatively spaced parallel guide lines or markings 7 which in turn are adapted to be indicated by numerals or othersuitable nomenclature 8 diagonal corner tongues 3' and 5' is such as to provide an intermediate piece 20, whose opposite extremities are coated on one face with an adhesive 21.

Thus, it will be understood that with engagement of the left side of the book cover in the left and partly folded side of thesheet 1 the opposite side of this cover is adapted to be covered by the protector by first marking the guide lines or markings 7 upon thetongues 8 and 5', then folding such tongues along the indicated guide markings inwardly and transversely of thenr selves, whereupon the intermediate top and bottom portions of the right side of thesheet 1 are folded upon themselves on a straight lineaover the top and bottom of the book cover so as to be arranged adjacent but slightly beyond the adjacent marginal portions of the book cover side. At this time, the intermediate portion 20 is folded inwardly upon itself along a straight line over the outer portion of the book cover side The forming or arrangement of theseand the coatedextremities 21 are moistened and the same then pressed into permanent engagement with adjacent portions of the inwardly.folded top and bottom end portions. Thus, a complete bool: cover protector is afforded.

From the foregoing, it will be understood that I have provided a simple, but highly efficient form of book cover protector, the construction or formation of the same being such as to provide a one piece re-enforced adj ustable book cover protector which may be made of various or different grades of paper or other suitable flexible material; (116 size of which protector may be properly and quickly fitted to books of different or varying dimensions, since no cutting is required, and folding of the cover protector is rendered simple and accurate by means of guide lines or markings hereinbefore described.

The corners of this book cover protector are so designed that the folding in thereof, according to directions, gives double thick ness and extra protection for several inches at each corner of a book so covered and protected without sacrificing, in the least, strength or durability of the cover; the surface or exposed face of the cover protector being perfectly smooth and hence, providing an important and advantageous feature in this respect, since an uneven surface has been found extremely objectionable due to the liability of the engagement of various objects therein with the tearing or premature wearing of the protector.

The tongues 2, 3, 4:, 5, 10, 10', 11, 11', 3 and 5 occurring at the top and bottom of the various sheets and in the centers thereof provide re-enforcement and if properly folded, protect the book at those points most needed. Certain of these tongues are curved in a way to lend materially to the strength and durability of the same and in this connection, it should be mentioned that if desired, the tongues may be formed in their respective sheets of the protector by being cut for certain distances and then perforated or scored for short distances inwardly, thus permitting their severance from the body portions of their respective sheets only as necessary or as is required.

Manifestly, the various constructions shown are capable of considerable modification, and such modification as is within the scope of my claims, I consider within the spirit of my invention.

I claim 2- 1. A book cover protector comprising a sheet of material having diagonally disposed tongues formed in the corner portions there of and adjacent the opposite ends of the same, the extremities of those free portions of the opposite sides between said tongues being adhesively coated upon certain of their faces, and opposed transversely extending tongues arranged adjacent the center portions of the top and bottom of the sheet.

2. A book cover protector comprising a sheet of material having diagonally disposed tongues having outwardly diverging edges formed in the various corner portions thereof, the top and bottom portions of said sheet being cut away adjacent the central portions thereof, a strip joined to one face of said sheet along its center disposed transversely of the same and having its opposite extremities overlying said cut away central portions of the top and bottom portions of the sheet, the extremities of those free portions of the opposite sides of the sheet between the diagonal converging tongues being adhesively coated upon certain of their faces, and transversely arranged relatively .spaced parallel guide markings inscribed upon portions of each of said diagonal tongues and those por tions of the strip overlying said cut away top and bottom central portions.

3. A book cover protector comprising a sheet of material having diagonal tongues formed in the same adjacent its various corners, each of said tongues being provided with relatively spaced transversely extending parallel guide markings, the extremities of those free portions of the opposite sides of the sheet between the diagonal tongues being adhesively coated upon certain of their faces, one side of said sheet being folded and having the bottom portion thereof permanently joined by the adjacent adhesively coated extremity and the upper portion of such folded sheet being open, and opposed transversely extending tongues arranged adjacent the center portion of the top and bottom of said sheet, portions of said transversely extending tongues being provided with relatively spaced transversely extending parallel guide markings, as and for the purpose set forth.

In witness whereof I have hereunto set my hand.

JARRETT E. THOMPSON.
