Application February 13, 1943, Serial No. 475,827

2 Claims. (01. 129-1) This invention relates to improvements in book binding. It is, more particularly, an object of the invention to provide a binding device capable of advantageous and economical use in the binding or securing of the pages or sheets of books, magazines, pamphlets, etc., in juxtaposed relation and against displacement.

Furthermore, it is an object of the invention to provide a device of the above stated character, wherein no use, or an absolute minimum of use, of metal fasteners is involved.

Another object of the invention resides in the provision of binding means so associated with the treated leaves, pages or sheets of the same or any thereof may be released for removal without disturbing the bound security of the remaining ones, and if desired, replaced and rebound in l the original assembly.

Other objects of the invention will be in part obvious and in part pointed out hereinafter.

In order that the invention and its mode of operation may be readily understood by those skilled in the art to which it appertains, I have in the accompanying drawings and the detailed description based thereupon, set out several embodiments of my invention.

Having more particular reference to the drawings, in connection with which like characters of reference will designate corresponding parts throughout, and referring to the type of invention disclosed in Figures 1-6, inclusive, the numeral I designates the cover of the improved invention, the same being preferably, though not necessarily, formed of stock or material somewhat heavier than that from which the double sheets orpages 2 are formed. The cover sheet I, as shown in Figure 4, is formed with an intermediately disposed and transversely extending slot or way 3, the opposite ends of which, as will be noted upon reference to Figure 4, are terminated inwardly of the opposite transversal edges or marginal portions thereof. The double sheets or leaves 2, it may be noted, are of substantially the same size and shape as that of the cover sheet 1, though if desired, they may be somewhat smaller, for reasons well known and appreciated in the art. Corresponding intermediate portions of each of said double sheets or leaves 2 are formed with marginally opening and inwardly extending slots or ways indicated at 4, the respective depths of which are such as to approximately correspond with the widths of those portions of the cover sheet I outwardly of the opposite extremities of the slot or way 3 in the latter. Moreover, the respective widths of these slots or ways 4 approximately correspond to the width of the slot or way 3, aforesaid, formed in the intermediate portion of the cover sheet I.

In assembling the constituent elements I and 2 (the cover sheet I and the double sheets or leaves 2) preparatory to their arrangement or binding in book, pamphlet or like formation, as

shown in Figures 1, 2 and 3 of the accompanying drawings, the double leaves 2 are arranged in juxtaposed or aligned relation so that their respective marginal opening slots or ways 4 register one with the other. The cover sheet I is now arranged over the outermost of the thus juxtaposed double sheets or leaves 2 in such a manner that its intermediate transverse way 3 longitudinally aligns with the sheet or page provided slots or ways l. Thereupon, those portions of the cover sheet I outwardly of the opposite ends of its said slot or way 3, i. e., preferably along the line indicated at 5, are slightly inwardly depressed, causing them to be received in and through the adjacent and registering slots or ways 4 of the double sheets 2. At this time, a locking or connecting rod i, whcse length approximately corresponds to the intermediate width of the cover sheet I, is longitudinally passed through the inwardly extended or flexed portions of the cover sheet I, that is to say, through the loops or sleeves thus formed by the flexing or bending of these portions of the cover sheet along the several dotted lines hereinbefore identified by the numeral 5. As the connecting rod 6 is passed through one of the said inwardly extended portions of the cover sheet I, as clearly indicated at I in Figure 2, it is engaged with the adjacent intermediate portion of the innermost double sheet or leaf 2, as clearly shown at 8, whereupon it is engaged by the opposite inwardly flexed or bent intermediate portion of the cover sheet I, as indicated in Figure 3 by the numeral 9. The connecting rod 6, when in connecting or operative position, is so arranged that its opposite ends are immediately adjacent the opposite transverse marginal portions of the cover sheet I and the double sheets 2, though in some instances, and if desired, its opposite ends may be spaced slightly inwardly of these opposite transverse marginal portions.

With the connecting rod I} thus engaged with the cover sheet I and the double sheets 2, the assembly is transversely folded along the aforesaid lines and hence, along the adjacent intermediate portions of the sheets 2, i. e., the dotted line II) of the sheet 2 shown in Figure 5.

Sheets or leaves 2, bindingly secured as above described, will be assured retention in booklet, pamphlet or like formation or relationship. Moreover, if desired, any particular one or more of such sheets 2 may be readily removed from the assembly merely by disengaging the connecting rod 5 therefrom and from the cover sheet I-- removing the particularly desired sheet or sheets 2 and then reassembling the same in the manner hereinbefore explained.

The connecting bar 6, should it be so desired, may be provided with means whereby to prevent its undesired sliding-like disengagement from the cover sheet I and the double sheets 2 by means of various devices well known in the art, viz, the rod may have its oppc-site ends slightly bent or it may be bent at one or more points throughout its length, thu causing it to have frictional binding engagement with the adjacent and contacted portions of the cover sheet and the double sheets 2 when arranged in operative position with respect thereto.

In Figures 7-12, inclusive, I have shown a somewhat modified form of binding wherein the numeral II represents the cover sheet of the book, booklet, magazine, etc., being preferably, though not necessarily, formed of material or stock of a sufficiently heavy gauge or weight to withstand the rigors of use to which it will be subjected. This cover sheet II is of size and shape whereby it will provide forward and rearward covers for the book, i. e., when transversely folded intermediately of itself, as indicated in Figure 7. An intermediate portion of the cover or cover sheet II is formed with a rectangular transversely disposed slot or way I2, the ends of which terminate in spaced relation to the adjacent and opposite transverse marginal portions of the sheet, as shown in Figure 10. When in use, those portions of the cover sheet between the opposite ends of the way I2 and the adjacent transv'ersal marginal portions of said sheet are inwardly folded along the dotted lines indicated by the numeral I3 and an intermediate parallel fold it is also formed in each of said portions but, as shown in Figures 8 and 9, in an opposite direction to that in which the folds I3 are effected. Thus, it will be seen that inwardly disposed substantially V-shaped portions IE will be provided by the referred to opposite portions of the cover sheet II, i. e., those portions of the same outwardly of the opposite ends of the transverse way I2. The leaves or pages of a book, booklet, magazine, etc., to be bound according to and through the instrumentalities of my invention, are of double sheet formation, as designated at It. That is, the length of each of such double sheets is such that when they are folded transversely and intermediately of themselves,

" they will provide leaves or pages of respective widths such as will be effectually received within or housed by the folded cover sheet II. The double sheets I6. are formed with marginally opening transversely aligned slots or ways IT in their respective intermediate portions and the widths of such slots or ways are preferably slightly greater than the widths of the inwardly disposed V-shaped portions I5, above described. Also, the respective depths of the slots or ways I1 approximately correspond with the lengths of these inwardly disposed V-shaped portions I5, hence, permitting of their comparatively snug introduction therethrough in the manner shown inFigure 8.

In assembling the sheets II and IE5 (the cover sheet and the double sheets or leaves) preparatory to their binding in book, booklet, magazine or like formation, as shown in Figures 7 and 8, the double sheets I6 are arranged in juxtaposed and aligned relationship in order that their respective marginal opening slots or ways I I will "be inregistration one with the other, and are then collectively folded transversely of themselves along the line It. The cover sheet II, thereupon, is arranged over the outermost of the aligned double sheets It in such a manner that its inwardly disposed substantially V-shaped formations l5; are engaged and extend through the aligned ways II of said double sheets I6, as clearly shown in Figure 8 of the accompanying drawings. At this time, a locking bar I9, made of cardboard, plastic, etc., is longitudinally passed between the inwardly disposed -V-shaped portions I5 and the intermediately folded portions I8 of theidouble sheets I6. It will be noted that the length of said locking bar approximately corresponds to the depth of the thus interconconnected or bound double sheets It and cover II; also, that its opposite ends are adapted to be arranged adjacent the transversal marginal portions of both the sheets I6 and II. Due to the fact that the width of the locking bar I9 substantially corresponds to the space between said folded portions I l and I8, it will be understood that the resulting frictional engagement with such portions will act to releasably, yet firmly, secure it against undesired sliding dis placement therefrom. I

A book, booklet, magazine or like, having it cover sheet and leaves or pages bound as described in the immediately preceding embodiment of my invention, will be positively retained in assembled or collated relation, although if desired, certain of the double leaves or sheets may be selectively removed therefrom, merely by sliding the locking bar I 9 out of engagement with the inwardly disposed V-shaped portions I and the intermediately folded portions I8 of said sheets I 6. At such time, the desired double sheet or leaf may be removed and the remaining leaves and the cover sheet reassembled in the manner above described.

It may be desirable that the locking bar I9 shall be provided with positive means for preventing its unwarranted or unwanted slidable displacement from engagement with the aforesaid double sheets I6 and cover sheet I I. To this end, I propose that type of modified form of locking bar illustrated in Figures 13 and 18 of the accompanying drawings and designated by the numeral I9. Also, if desired, the relative formations of the cover sheet I I and the double sheets or leaves I6, as shown in the Figures and 11, may be reversed, as shown in Figures 16 and 17. In this particular form of the invention, the cover sheet II is formed with relatively transversely opposed intermediately arranged marginal opening slots or ways IT, as shown in Figure 16, and that portion of said cover sheet intermediately of the inner ends of said slots or ways I1 is adapted to be inwardly folded along the lines I3 and then reversely folded along the line I4, whereby to provide an inwardly disposed cross-sectionally V- shaped portion I5. The various double sheets or leaves I'B' have their corresponding intermediate portions each formed with transversely disposed slots or ways I2, the opposite ends ofwhich, as will be noted upon reference to Figure 17, terminate inwardly of the opposite transverse mar-' ginal portions of their sheets. To assemble the sheets II and I6 into book, booklet, magazine or the like form, the sheets I6 are transversely collated and then folded upon themselves along the line I8, which folding, as will be understood upon reference to Figures 14 and 17, will substantially bisect the transversely disposed slots or ways I2. At this time, the inwardly disposed cross sectionally V-shaped portion I 5' of the cover sheet II is inserted or passed inwardly through the registering slots or ways I2 of the sheets I5, as is well shown in Figures and 16, hence, interconnecting said sheets II' and I6. Thereupon, the locking bar I9 is slidably inserted or passed between the folded outer portions of the sheets I6 and the inner end of the cross sectionally V-shaped portion I5 imtil its opposite end are substantially adjacent or aligned with the opposite transversal marginal portions of the cover sheets or double sheets or leaves, as is seen in Figure 13. To prevent undesired sliding movement of the locking bar I9 from such position or engagement, the normally inner longitudinal edge of said bar is inwardly shouldered or rightangularll cut as indicated at 20. The shouldering of the bar I9, as at 2B, is so effected that such shoulder will engage over the opposite ends of the inwardly folded portion I4 of the V- shaped portion I5, as clearly shown in Figures 13, 14 and 15, and hence, will securely though releasably lock or secure said bar against undesired sliding movement with respect to the cover sheet and double sheets II and I6.

Manifestly, the construction shown is capable of further modification, and such modification as is within the scope of my claims, I consider within the spirit of my invention.
