ful Improvements in Cumulative Books, of

which the following is a specification, the same being a division of application Serial No. 444,037, nieu July i7, 190s.

This invention is intended particularly for use in the Vbinding of encyclopedias or other records of current events, or informa tion which it is desirable to supplement from time to time by means of printed inserts containing currentY news, i'evised records or other information required to keep the bookV up to date withoutcthe necessity for publishing separate supplementary volumes, which are inconvenient for reference and wasteful of space and disturb library arrangements.

The present invention relates particularly to the method of binding the original volume in such a manner that inserts can'be added from time to' time without distorting the shape or arrangement of the original volume which is originally bound in such manner as to be of equal thickness from back to edge, like library books of the ordinary character, in which respect it differs radically from ordinary scrap books or similar books having stubs orfilling pieces bound therein, which materially thicken the back of the book and render it unfit for use as a library book.

The invention further `consists in the means provided for securing the inserts inV such manner that the purchaser of the book can readily apply them without difficulty and in a perfect manner, so that the book will not be disgured when the insertions are made.

The invention consists in the features of construction and combination of parts hereinafter described and claimed. Y

In the drawings, Figure 1 is a perspective view of the book laid open, with the temporary leaves in place; Fig. 2 a similar view showing the temporary leaves removed in preparation for applying the inserts; Fig. 3 a view showing the temporary leaves partially torn away; and Figs. 4 and 5 perspective views showing two styles of inserts. lThe book comprises a vplurality of permanent printed leaves 6, of the usual character,

bound together in the form of an ordinary library book. At suitable points the book is interleaved with tem orary leaves 7 and S arranged in pairs, whic i leaves are adapted to be torn away along weakened tearing lines 9 and 10Vto leave permanent stub portions 11 and 12, one of said stub portions being of greater width than the other to provide a projecting edge adapted to have the insert pasted thereon, and the other stub portion serving to compensate -for the extra thickness of paper at the point where the insert is pasted.,

The inserts intended for the book above described are preferably of the form shown in Figs. 4 and 5. Fig. 4 shows an insert consisting of a main leaf 13 and a fly leaf 14 pasted onto the main leal' near its inner edge, leaving a pasting edge 15 of single thickness to be pasted onto .the projecting portion of the wider stub in position to bring the inner edge of the insert in contact with or just outside of the outer edge of the narrow stub. In Fig. 5 is shown an insert having a body portion 16 of double thickness, and a pasting edge 17 of single thickness. These'forms of insert can be used indiscriminately in the same book. Where the volume of inserted matter is small and can be printed on one or two pages, it is desirable to use an insert of the form shown in Fig. 5, but where three or four pages are required the insert of Fig. 4, consisting of a main leaf and a fly leaf, will be found more desirable.

The book, when. originally published, will be of full size and standard shape, the presence of the temporary leaves serving to give the book a uniform thickness throughout, and this form of book will be sold to the purchaser and installed in his library. Thera after, when inserts are printed and published from time to time, they can be applied without thickening thepbook or distorting it in Aany way. In making the insertions, a pair of temporary leaves will be torn out, leaving stubs, one projecting beyond the other suiiiciently to afford a pasting surface. On the pasting surface so afforded the inner or thin edge of the insert is pasted, and this edge, being of single thickness, in conjunction with the stub portion to which it is pasted will give a double thickness at the pasting point, which double thickness, at the point of insertion, will be uniform throughout the entire book, so that when the insert is applied l the book Will be restored to its original thickness, and the reduction in thickness ol the book, occasioned by the removal of the temporary leaves, Will be fully compensated for.

The method ol forming the temporary leaves in pairs of single thickness is one which in ncwise interferes with the binding of the book and permits ordinary paper stock to be used l'or the temporar leaves which can be weakened along the intended tearing line in any suitable manner, as by means ol cuts or perforations, although it is not intended to limit the invention to a weakened tearing line, since a similar result could be obtained if the tearing line Were merely indicated by a printed. line, permitting the user to remove the intended portion by means oll a straight edge or ruler.

In speaking` ol temporary leaves, it is not intended to limit the invention strictly to the use of blank leaves, since, obviously, such temporary leaves might have mattei' printed thereon; and it will be understood that such language refers to any leaves, blank or printed, Which are bound into the book, with the understanding or intention that parts of such leaves may be removed, along an indicated tearing line, at some subsequent time, il desired, to make room for inserts. i

l/Vhat l regard as new and desire to secure i by Letters Patent is: l

l l l l. A book, interleaved, at the points intended to receive inserts, With leaves in pairs,

each el' said leaves having, near its inner edge, a tearing line dividing the leall into an inner permanent stub portion and an outer temporary portion, one ol' the stub portions projecting beyond the other, in combination With an insert having a thickness equal to the combined thickness olA the two stub portions, save only at its inner edge, said edge being oi' the thickness ol' one ol' the stub portions, the insert being o` a size to bring its Outer edges into register with the permanent leaves ol the book when the inner edge ol' the insert is pasted to the projecting stub portion, substantially as d escribed.

2. A book, interleaved, at the points intended to receive inserts, with leaves in pairs, each ol.l said leaves having, near its inner edge, a weakened tearing line dividing the leall into an inner permanent stub portion and an. cuter temporary portion, one el' the stub portions projecting beyond the other, in combination with an insert having a thickness equal to the combined thickness ol` the two stub portions, save only at the inner edge, said edge being ol' the thickness ol' one of the stub portions, the insert being ol' a size to bring its outer edges into register with the permanent leaves ci' the book when the inner edge oll the insert is pasted to the projecting stub portion, substantially as described.
