An Improved Method of Binding Books or in Connecting Leaves of
Books or Pamphlets for Binding or Reception of Covers thereto.
I, JOSEPH LEWTHWAITE, of 17, Seaside, Eastbourne, Sussex, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a novel method of preparing the crease portions of
leaves of books, pamphlets, and the like by stamping through portions at the
rear of the leaves in such manner that said stamped portions can as flaps be
folded or pushed outwardly at the back and be the means by glue or paste attach-
ment of connecting the leaves up singly or in series for affixing the covers
of any kind, such as the paper covers of pamphlets, limp cloth, limp leather,
or stiff backs and stiff covers, the object being that each leaf is secured in such
manner that the pamphlet or book can be opened out flat at any part without
risk of breaking or tearing, as with the present system of wire sewing of
pamphlets or the thread sewing of books.
For the purpose of my invention, I stamp and sever a portion of each or each
alternate leaf with, say, a dovetail shape of cutting near the back edge ter-
minating the end slits at the creasing part, so that the stamped loose portion
forms a kind of flap capable of being pushed outwardly which I then glue or
paste together to form a section".e. four or more double leaves, thus any
number of sections can be connected to constitute a pamphlet or book ready for
the reception of the cover without any sewing or stitching, each leaf being
securely held and the pamphlet be opened out flat for reading or other purpose.
I have referred to each leaf as being so stamped or prepared to form the flaps,
but the stamping may be in one leaf only of a double leaf, and when the flaps
of several of such sections of double leaves are prepared I prefer that the stamp-
ings be made at two or more different parts in the series, so the bulk of flaps
are arranged at different parts of the back and thus obviate an excess of bulginess
at any one part.
Some of the stamped slits may be only at the middle of the creasing line, and
others can be stamped near the top and bottom respectively, or at top or at
bottom only, the length of the slit ensuring the absolute connection of all the
leaves of which the pamphlet or book is composed.
The flaps when cemented in series may have a cloth back liner glued to them
to give the back a neat appearance previous to the covers being applied.

I, JOSEPH LEWTIIWAITE, of 17, Seaside, Eastbourne, Sussex, Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to a novel method of preparing the crease portions of
leaves of books, pamphlets, and the like by stamping through portions at the
rear of the leaves in such manner that said stamped portions can as flaps be
folded or pushed outwardly at the back and be the means by glue or paste attach-
ment of connecting the leaves up singly or in series for affixing the covers
of any kind, such as the paper covers of pamphlets, limp cloth, limp leather,
or stiff backs and stiff covers, the object being that each leaf is secured in such
manner that the pamphlet or book can be opened out flat at any part without
risks of breaking or tearing as with the present system of wire sewing of
pamphlets or the thread sewing of books.
For the purpose of my invention, I stamp and sever a portion of each or each
alternate leaf with, say, a dovetail shape of cutting near the back edge ter-
minating the end slits at the creasing part, so that the stamped loose portion
forms a kind of flap capable of being pushed outwardly which I then glue or
paste together to form a section e. four or more double leaves, thus any
number of sections can be connected to constitute a pamphlet or book ready for
the reception of the cover without any sewing or stitching, each leaf being
securely held and the pamphlet be opened out flat for reading or other purpose.
I have referred to each leaf as being so stamped or prepared to form the flaps,
but the stamping may be in one leaf only of a double leaf, and when the flaps
of several of such sections of double leaves are prepared I prefer that the stamp-
ings be made at two or more different parts in the series, so the bulk of flaps
are arranged at different parts of the back and thus obviate an excess of bulginess
at any one part.
Some of the stamped slits may be only at the middle of the creasing line, and
others can be stamped near the top and bottom respectively, or at top or at
bottom only, the length of the slit ensuring the absolute connection of all the
leaves of which the pamphlet or book is composed.
The flaps when cemented in series may have a cloth back liner glued to them
to give the back a neat appearance previous to the covers being applied.
My invention will be understood by the aid of the annexed drawings.
Figure 1 face view of a single leaf of paper with three dovetailed shapes of
cuts from which flaps are formed when folded back for attachment to corresponding
flaps of other sheets or leaves of paper.
Figure 2 corresponding view of a single leaf or sheet of paper, or other
material in which the cutting of the flaps is reversed, the dotted lines, as in
Figure 1, showing the fold back flaps.
Figures 3 and 4 show the sheets represented at Figures 1 and 2 respectively
with the flaps folded back and exposing the gaps or spaces from which the flaps
have been removed by the back folding operation.
Figure 5 perspective view of a double or folded sheet of paper, from either
leaf of which the flaps may be cut or partly from one leaf, and partly from the
other, so that when such flaps are folded back the several flaps of the several

page_text: leaves can be glued or pasted to one another to connect the several in-sets or
sections of which the pamphlet or book is to be composed.
The several letters of reference apply to all the figures.
According to Figure 1, the dovetail cut through the paper A, the flap B
has its narrowed part next the edge C of the paper, consequently the wider
portions D, D, of the flaps B are ready when folded to appear beyond the edge
to be pasted or glued to corresponding or other flaps of the adjoining sheet,
leaf, or piece of paper and so on determined by the thickness of the pamphlet
or book.
Referring to Figure 2, the flap B has its widest part D, D, next the edge C
of the paper A and its narrowed edge E, E, is farthest from the edge. By this
method, less glue or paste at the fold back portion of the flap B would be required.
The method of cutting and forming the flaps from single leaves somewhat
thickens the back of the pamphlet or book when made up or bound because a
portion of each flap lies on the leaf, but by cutting and forming the flap from
a foldable or double leaf, the cut is from the folding crease F, and the flap forms
an extension therefrom, which flaps in quantity and glued or pasted together
from different parts in the height of the book are rolled or clustered between
the back of the book and the back of the binding and not observable when the
binding is completed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. Severing or cutting portions of single leaves or sheets of paper A near one
edge C to form foldable flaps B, B, therefrom, portions of such flaps B, B, when
folded back being freely exposed beyond said edge C for reception of an adhesive,
as specified.
2. Severing or cutting portions of double or folded leaves or sheets of paper A
near the folding crease to form flaps B, B, therefrom to be folded outwardly
from said folded crease as means by glue or paste of securing the flaps B together
and in cluster, as specified.
3. Severing or cutting, such as by stamp cutter or otherwise, dovetail slits in
or from sheets of paper or other material from near the edge of single sheets,
or from the folding crease line of double sheets to form flap like pieces foldable
outwardly for connection by glue, paste, or other adhesive and forming extensions
from the back in clusters, as and for the purpose specified.
4. Connecting the back portions of sheets of paper or other material by means
of portions of such sheets which are cut and folded backwardly and extending
beyond the normal backs of such sheets for connection with other or corresponding
portions by glue, paste, or other means, substantially as specified for the purpose
set forth.
