PROVISIONAL SPECIFICATION.
Improvements in Bookbinding with the Object of Obtaining Greater
Flexibility and Strength.
I, THOMAS ELI GIBSON General Manager of Mackie and Company Limited
Guardian Office, Warrington, Printers and Publishers, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object an especially strong and flexible form of binding
for school-books, for free public libraries and other places where books get rather
rough illusage and require extra strong and flexible binding. In carrying out
my invention the first and last sections are guarded with a fly-leaf; the end
papers are lined round with jaconet or other suitable strong durable flexible
material; this is left loose in front and inserted with the tapes into split boards.
The back fly-leaf of the end papers where jaconet is lined and fastened down is
pasted to the loose fly leaf that round the first and last sections. In making
the cloth jointed end papers the outside fly leaf is left about a quarter of an inch
from the back so that when pasted down the cloth joint and jaconet coming
together give greater flexibility and strength to the opening of the back as the
back is as it were a second- joint or bending place beyond the actual seam.

COMPLETE SPECIFICATION.
Improvements in Bookbinding with the Object of Obtaining Greater
Flexibility and Strength.
1, THOMAS ELI GIBSON, General Manager of Mackie and Company Limited,
Guardian Office, Warrington, Printers and Publishers, 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 has for its object an especially strong and flexible form of
binding for school books, for free public libraries and other places where books
get rather rough usage and require extra strong and flexible binding.
The invention is best described by aid of the accompanying drawings, in which,
Figure 1 is a perspective view showing a portion of a book opened at the cover
which is shown partly torn;
Figure 2 end view of same.
In these figures, the first and last sections A B are guarded with a fly leaf CC,
the end papers P and fly leaf C are lined round with jaconet D D or other
suitable strong durable flexible material; this is left loose in front and inserted
with the tapes F into split boards G. The back fly leaf of the end papers H,
where jaconet is lined and fastened down, is pasted to the loose fly leaf C that is
round the first and last sections. In making the cloth jointed end papers, the
outside fly leaf is left about a quarter of an inch from the back, so that when
pasted down the cloth joint and jaconet coming together give greater flexibility
and strength to the opening of the book as the back is as it were a second joint or
bending place beyond the actual seam.
This method of binding does not require backing the books with the hammer,
thus enabling the books to open quite flat. It will be noticed also that the play

page_text: of the cover is independent of the back or body of the book. The invention may
be equally well applied to tight or loose backs."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1. The method of bookbinding substantially as herein set forth, whereby great
flexibility and strength of binding are secured.
2. The combination of the jaconet binding in addition to the tapes, the former
inserted with the tape into the split-boards and pasted between a loose fly leaf on
the first or last section and the end papers.
