PROVISIONAL SPECIFICATION.
Improvements in or relating to Book Binding.
I, ROBERT BAGSTER of 15 Paternoster Row, in the County of London,
Publisher do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the binding of books having cloth
covers, its object being to make the back so flexible that the leaves can be turned
right back, and the book lie open in any place without cracking, breaking
or starting," which has never been done before.
In carrying out my invention I proceed as follows:-
The book is folded and rolled in the usual manner and then sewn preferably
by a Smythe sewing machine, but in the "forwarding" process, that is making
the backs, I glue the flat backs with a flexible glue, heated at or near boiling
point, very much hotter than is usual in book-binding. I then very carefully
rub the glue into the back with a cloth or folder, and before the glue is cold
proceed to "round" the book and to "back" it in an ordinary backing machine.
I then re-glue the back with flexible glue, at the same high temperature, and
place upon it a strip of binders' cloth, rubbing on this cloth thoroughly so as
to obtain the most intimate cohesion, and to force the glue well in to the sheets
of the book. The cloth cases or covers can then be stuck on to the books in
the usual way.
To obtain the degree of flexibility possible in my system of book-binding it is
absolutely essential that the glue should be kept very hot as if it is allowed to
chill the flexibility is greatly diminished.

Improvements in or relating to Book Binding.
I, ROBERT BAGSTER of 15 Paternoster Row, in the County of London,
Publisher, 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 improvements in the binding of books having cloth
covers, its object being to make the back so flexible that the leaves can be turned
right back, and the book lie open in any place without cracking, breaking
or "starting," which has never been done before.

To obtain the degree of flexibility possible in my system of book-binding it is
absolutely essential that the glue should be kept very hot as if it is allowed to
chill the flexibility is greatly diminished.
I may if desired extend the method of glueing employed in backing the book
to the attachment of the case or cover to the book. The principal part of this
operation consists in rubbing the glue into the joint until it is well fixed and
then allowing it to cool. This treatment results in very intimate cohesion
between the book and the cover, and the binding is extremely supple and flexible.
The glue employed in the processes hereinbefore described may be any suitable
flexible glue known in the trade, such for example as Procter & Bevington's
Flexible Glue.
Having now particularly described and illustrated the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is :-
1. The herein described flexibly bound book.
2. The method of book binding substantially as described whereby the backs
are made more flexible than heretofore without impairing their durability.
