Improvements in Bookbindings.
We, WILLEM BENEDICTUS and JOSEPH BENEDICTUS both of Zuid blaak,
Rotterdam, Holland, Manufacturing Stationers do hereby declare the nature of
this invention to be as follows:-
According to this invention the leaves of a book are stitched in sections in linen
binders which are strengthened at top and bottom with a series of strips of card-
board, millboard, or other suitable material, so arranged that they form hollow
expanding hinges, which afford such easy play to the leaves of the book, that
whenever and wherever it is opened, such leaves lay so nearly perfectly flat that
entries can be made therein or thereon far more conveniently than in books bound
in the ordinary manner, while the linen binders materially strengthen the back of
the book, and increase the durability of the binding. Another advantage of this
invention is that the leaves of the book never work loose, while it is impossible to
tamper with the book by removing one or more leaves therefrom without detection.
The thickness of the strips of cardboard, millboard, or other material forming the
hollow expanding hinges, is regulated by the number of leaves in each section, the
various sections of leaves in a book being each composed of a similar number of
leaves.

COMPLETE SPECIFICATION.
Improvements in Bookbindings.
We, WILLEM BENEDICTUS and JOSEPH BENEDICTUS both of Zuidblaak,
Rotterdam, Holland, Manufacturing Stationers 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 :-
According to this invention the leaves of a book are stitched in sections in linen
or canvas binders, which are strengthened either at top and bottom, or for their
entire length, with a series of strips of cardboard, millboard, or other suitable
material, hereafter termed " stays,
so arranged that the binders when fitted
therewith form hollow expanding hinges, which afford such easy play to the leaves
of the book, that whenever and wherever it is opened such leaves lay so nearly
perfectly flat that the book can be read and entries can be made therein far more
conveniently than in books bound in the ordinary manner.
At the same time the
linen or canvas binders materially strengthen the back of the book and increase
the durability of the binding.
One advantage of our invention is that the leaves of the book never work loose,
while it is impossible to tamper with the book by removing one or more leaves
therefrom without detection. The thickness of the strips of cardboard, millboard,
or other material forming the stays is regulated by the number of leaves in each
section, the various sections of leaves in a book being preferably, but not
necessarily, each composed of a uniform number of leaves.

page_text: Figure 1 shews the strips or stays with which each binder is furnished extending
continuously the entire length of the binder.
Figure 2 shews such strips or stays mounted between the two thicknesses of
linen or canvas of which each binder is formed.
Figure 3 shews the binder doubled forwards in half lengthwise with any con-
venient number of sheets forming one section of the book sewn therein.
Figure 4 shews such binder doubled backwards in half lengthwise to form the
hollow expanding hinge.
Figure 5 shews an end view of such hinge as it appears when open.
Figure 6 shews the various sections of the book stitched together and furnished
with the ordinary binding tapes for securing it to the cover.
Figure 7 shews an end view of a book open and bound according to our inven-
tion and
Figure 8 shews the strips or stays fitted to the top and bottom of the binder in
short lengths instead of extending continuously along its entire length as shewn in
Figure 1.
Each binder c, consists of two thicknesses of linen or canvas between which strips
of cardboard, millboard, or other suitable material forming stays a, a, b. b, are mounted
as shewn in Figure 2. The dotted lines in this figure and also in Figures 3, and 4,
indicate the position of the stays when so mounted. The outer stays are made about
twice the width of the inner ones in order to give greater strength to the back of the
hinge, and the stays are placed at convenient distances apart as shewn so as to allow
When the binder
sufficient play to the expanding hinge c' formed by the binder.
has been so prepared it is doubled in half lengthwise as shewn in Figure 3, thus
forming a longitudinal central fold therein, wherein one section of the book d, con-
sisting of any convenient number of sheets is sewn. The binder is then folded
backwards in the reverse direction as shewn in Figure 4 whereby it is converted
into the hinge c¹. When the various sections forming the book have been thus
prepared they are stitched together as shewn at Figure 6 and furnished with
binding tapes e whereby the book is secured to the cover in the ordinary manner.
Our invention is applicable to all kinds of books but is particularly valuable for
account books, books of record, and other similar books.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;
As a new article of manufacture a bound book wherein each section of the leaves
is provided with a hollow expanding hinge made arranged and fitted substantially
in the manner herein before described and shewn.
