IMPROVEMENTS IN BOOKS FOR HOLDING BILLS, LETTERS, SCRAPS AND SIMILAR ARTICLES
Year: 1884

page_text: I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co. Patent
Agents, Southampton Buildings London, in the County of Middlesex do hereby
declare the nature of said invention for "IMPROVEMENTS IN BOOKS FOR HOLDING
BILLS, LETTERS, SCRAPS AND SIMILAR ARTICLES 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 books for holding scraps and the like and for similar
purposes.
In books for holding scraps, letters and bills, and in books for similar purposes,
while the backs should be filled out and made firm, there should also be spaces
left between the leaves of the book sufficient for scraps or sheets of paper to be
placed between them, and, if desired, also attached to them.
This invention has for its object to secure the results above stated, and it consists
essentially in constructing a scrap or other similar book with leaves separately
provided at the back edge with at least two, but preferably three or more, parallel
reverse folds, either integral with the leaves or attached thereto so as to be
continuous therewith; the leaves at the said folds being interlocked or connected
with each other, and secured together and to a back binding if so desired, all
substantially as hereinafter described, whereby the leaves, making the book, at
their back edges are filled out and made firm, and at the same time a sufficient
space is left between more or less of the leaves for the reception of the scraps or
sheets of paper in connection with which the book is to be used.
In the accompanying drawing
Figure 1 is a perspective view of a leaf having parallel reverse folds at its back
edge in accordance with this. invention, the said folds being shown as partially
opened out.
.
Figures 2 and 3, are transverse vertical sectional views of a series of folded
leaves arranged together, the said: leaves being shown as opened out and thicker
than in practice.
Figure 4 is a transverse sectional view of a book from back to front, häving its
leaves folded and arranged together as shown in Figure 2,

page_text: .
hereinafter explained.
Figure 6 shows leaves folded as in Figure 5, but arranged together as shown in
Figure 3.
A indicates the covers, and B, the back binding of a book composed of a series
of leaves C.
Each leaf C, Figures 1 to 4, inclusive, has at its back edge three parallel reverse
folds, df and g, and the folds are of equal width, and each is integral with the
body h, of its leaf.
The folds for each leaf may be made separately and attached to each leaf
separately, making in substance a continuation of such leaf. The leaves C, having
folds d, f, and g, are placed (see Figures 2 and 4) with the part 1 of the body of
each leaf nearest to the fold d, and the fold d, within and between the folds f,
and g, of the preceding leaf. The several folds and leaves being thus secured and
bound together, have between the first two contiguous leaves at the back edges
thereof, the thickness of the two folds d and f, and between the third and fourth
leaves and so on to the last leaf, the thickness of three folds, viz. ; two folds,
d and f, of the first leaf in the order of number of each pair of leaves, and the
fold g, of the leaf preceding the first leaf in the said order of numbers.
Folded leaves arranged as above described are bound together at the back and
to a back binding B, in any suitable manner, and when so bound, while the back
is filled out and made firm there is left between any two contiguous leaves of the
book after the first, a space n (see Figure 4) equal in substance to three thicknesses
of a leaf the said three thicknesses being made up in one of its three parts by the
fold g, of one of said contiguous leaves, and in the other two of its three parts by
the two folds d f of the other of said contiguous leaves. These spaces n, left as
aforesaid between the several leaves, afford opportunity, as is evident, for the
'insertion of letters, bills, paper scraps, or the like which may or may not be
attached to either of the said leaves.
!
In the arrangement shown in figure 3, the leaves are folded, and the folds of
several leaves are placed together in substantially a similar manner to that shown
in Figures 2 and 4 as hereinbefore described, but with this difference, that the
leaves come together in pairs. After the first leaf and between the surface of
the second leaf of each succeeding pair which is contiguous to the surface of the
first leaf of the next pair, there are at the back edges of such leaves of the two
adjoining pairs six extra thicknesses of paper made up in each instance in four of
its thicknesses of the folds d and f of the first of the two pairs of leaves having
contiguous surfaces as stated and in the remaining two of the thicknesses of the
folds g g, of the pair of leaves directly preceding the said first pair of the said two
pairs of leaves.
In other words this arrangement of the leaves consists in placing the
corresponding folds of two leaves one within the other, and then placing such
pair of leaves having the folds of each situated in relation to the other within
and between the folds fand g, of another pair of leaves having the folds of the
one leaf placed in the corresponding fold of the other leaf as has been described.
Each leaf, in accordance with the foregoing description, has three folds, viz.
the folds d, f, and g at its back edge, but the fold. g, may be dispensed with,
and the leaves with the folds d, and f, arranged as shown in figure 5, which is in
accordance with the arrangement of the folds of the leaves shown in Figure 2.
except with the fold g out, or as shown in figure 6 which is in accordance with
the arrangement of the folds of the leaves shown in figure 3; with the same fold. g
out as above stated. In dispensing with the one fold g, of the leaves, it is plain
that a substantially similar result is obtained: but as is obvious, in such case
greater care would be required to arrange the leaves together than would be the
case were the leaves provided with the fold g, and therefore in view of this, it is
not intended to limit this invention to three folds of the leaves although such

page_text: number is preferable to any less number, and also to a greater, for apparent
reasons.
The widths of the leaf folds can be varied to suit different thicknesses of paper
used for the leaves, and to have their back edges even, for their better binding, or
being secured in the covers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is,
First In a book for holding scraps and for similar purposes, leaves having their
back edges folded reversely, and by such folds interlocked with each other and
secured, substantially as, and for the purpose, specified.
Second. In a book for holding scraps, and for similar purposes, leaves having
their back edges folded reversely, and by such folds interlocked with each
other, and secured to the back binding, substantially as, and for the purpose,
specified.
