page_text: LETTERS PATENT to Julian Bernard, of Club Chambers, Regent Street,
in the County of Middlesex, Gentleman, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OR PRODUCTION OF BOOTS, SHOES, AND OTHER
PROTECTORS FOR THE FEET, AND IN THE MATERIALS, MACHINERY, OR APPARATUS
EMPLOYED IN SUCH MANUFACTURE."
Sealed the 28th November 1854, and dated the 31st May 1854.
PROVISIONAL SPECIFICATION left by the said Julian Bernard at the
Office of the Commissioners of Patents, with his Petition, on the 31st
May 1854.
I, JULIAN BERNARD, of Club Chambers, Regent Street, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OR PRODUCTION OF BOOTS, SHOES, AND
OTHER PROTECTORS FOR THE FEET, AND IN THE MATERIALS, MACHINERY, OR APPA-
RATUS EMPLOYED IN SUCH MANUFACTURE," to be as follows:-
My said Invention relates,-
Firstly, to inserting nails or rivets for rendering more serviceable, and also
attaching wooden licels and soles to the other parts of such boots and shoes by
means of any suitable adhesive substance.
2ndly, to a novel method of manufacturing boots and shoes, or uniting the

page_text: different parts together, which is performed in a partial vacuum. The parts
to be united are placed in a chamber or compartment, such chamber being so
formed as to open or divide for the reception and disposition of such parts,
while a moveable slide or piston may be passed air-tight through and into
such chamber or recess, and made to press the parts together, a partial vacuum
being previously obtained by any suitable exhausting apparatus.
.
3rdly, to heating the material or adhesive surface of the parts to be united
while or after such parts have been suitably disposed of in their relative position
to each other.
4thly, to bringing the heating agent or apparatus to the parts to be heated,
instead of bringing such parts to the heating agent, and which may be performed
by passing a moveable heated hollow plate or chamber, heated by steam or
other means, between such parts immediately before being united or pressed
together, and which pressure I prefer to be imparted through an elastic medium,
and which may be performed by introducing india-rubber or other elastic
material, whether alone or in connection with a fluid introduced into or against
the parts to be pressed, whether such parts are pressed against a die, last, or
otherwise; and this process is more particularly intended for boots, shoes, and
similar articles united or partly put together by means of a suitable solution,
cement, or plastic material, and entirely remedies the objection of gas or air
preventing the proper adhesion of such parts.
5thly, to making or employing lasts in the manufacture of boots and shoes
with or in connection with elastic bottoms or other parts.
6thly, to casting, moulding, or forming the soles and heels upon the uppers,
or uppers and inner soles of boots and shoes, and which I prefer to perform in
vacuum.
And, 7thly, to apparatus and machinery employed in the immediately above
recited process, and which may be performed by placing or forcing the last
with the upper leathers, or the upper leather and inner sole properly adjusted
upon it, against a mould or die, which mould or die will fit close around the
-bottom-edge-of-the-last, but leaving a sufficient space or room in the die for
the sole and heel to be formed, forced, or poured into it in a plastic or other
suitable preparatory condition.
