in the sixteenth year of Her reign, did, for Herself, Her. heirs
and successors, give and grant unto me, the said Edouard Sy, Her

use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN BOOKBINDING," upon the condition (amongst others)
that I, the said Edouard Sy, by an instrument in writing under my

of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said Edouard Sy, do hereby.
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
This Invention consists of making the backs of two or more parts
longitudinally, and applying steel or other springs to the back in
order that books (particularly large ones) may open and close more
conveniently. And in order that my Invention may be more fully
understood, and readily carried into effect, I will proceed to describe
the Drawing hereunto annexed.

page_text: Figure 1, shews a perspective view of the back of a book con-
structed according to my Invention. A, is the back, which is con-
structed either of wood or metal; B, B, the plates to which the
covers are attached; C, C, springs of steel; D, shows the division
between the two parts of the back; and E, the hinge by which they
are connected together; F, F, show the hinges which connect the
plates B, B, to the back A; G, indicates the place where the
springs H, and I, are attached, when it is desired to use them in
place of the springs C; H, shows a spring of caoutchouc; I, a spiral
spring of copper or steel fixed by a screw.
Figure 2, shows another form of back constructed according to
my Invention, where the steel springs 1, 1, are hinged directly at
3, 3, to the plates 2, 2.
This back is intended to be covered with leather or other suitable
material, so as to have the appearance of a book bound in the
ordinary manner.
Having thus described the nature of my Invention, and the
manner of performing the same, I would have it understood that I
do not confine myself to the precise details herein mentioned; but
what I claim is, the improvements in bookbinding above set forth
and described.
In witness whereof, I, the said Edouard Sy, have hereunto set
my hand and scal, this Twelfth day of August, in the year of
our Lord One thousand eight hundred and fifty-three.
EDOUARD SY. (L.S.)
