AN IMPROVED MODE OF MANUFACTURING COCKS."
Year: 1858

page_text: LETTERS PATENT to Pierre Brunon, of Paris, (France), Manufacturer,
for the Invention of "AN IMPROVED MODE OF MANUFACTURING COCKS."
PROVISIONAL SPECIFICATION left by the said Pierre Brunon at the
Office of the Commissioners of Patents, with his Petition, on the
29th October 1858.
I, PIERRE BRUNON, of Paris, (France), Manufacturer, do hereby declare
the nature of the said Invention for "AN IMPROVED MODE OF MANUFACTURING
Cocкs," to be as follows:-
This Invention relates to an improved mode of manufacturing cocks out of
glass, crystal, or other similar silicious materials, and consists in casting the
same entirely in moulds of metal or other suitable material, so as to form in
one operation the hole for the passage of the fluids, and that for the plug to
fit in, this latter being cast in the same manner so as to require but very little
grinding off for tho plug to fit perfectly in the barrel of the cock.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Pierre Brunon in the Great Seal Patent Office on the
29th April 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PIERRE
BRUNON, of Paris, (France), Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said -Pierre Brunon, Her special licence that I, the said Pierre
Brunon, my executors, administrators, and assigns, or such others as I, the
said Pierre Brunon, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN IM-
PROVED MODE OF MANUFACTURING COCкs," upon the condition (amongst others)
that the said Pierre Brunon, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, 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 Pierre Brunon, 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:
This Invention relates to an improved mode of manufacturing cocks of glass,
crystal, china, or other similar silicious materials, and consists in running or
casting the said materials in the melted state in suitable moulds of metal or
other suitable material, so as to form in one casting the entire barrel or body
of the cock, provided with the passage for the fluid, and in the same manner
the plug provided with its perforations to fit in its respective barrel, by which
method but very little grinding is required for making the plug fit exactly in
the barrel of the cock.
In the annexed Drawings, Fig. 1 represents an outside view of my cock
provided with its plug; Fig. 2 represents a horizontal sectional view of the
same, taken over the middle of the barrel; the hole in the plug shows the

page_text: cock to be in the opened position, that is to say, with this hole exactly opposite
the passage of the barrel; Fig. 3 is a top view of the barrel of the cock. In
these Figures corresponding parts are represented by the same letters of
reference. A is the barrel or body of the cock, of which B is the plug,
provided with its knob or handle C; D is the passage for the fluids to pass
through, which passage may be either shut up or communicate with the
angular passage E of the plug, according to the position in which this latter is
turned, so as either to shut up the liquid in the passage D, or give it a free
ogress through E. My Invention allows of manufacturing cocks of glass,
crystal, china, or other silicious material at a much lower price than was
hitherto possiblo, and by my mode of casting the barrel and the plug, provided
with their passages, in metal or other suitable moulds, any required form of
cock may be cast in any suitable silicious material, and at the same time
receive any suitable cast ornaments.
Having thus described and particularly ascertained the nature of the said
Invention, and the manner in which the same may be carried into effect, I
would observe in conclusion that I do not confine or restrict myself to any
particular form of cock or silicious material of which the same may be cast;
but what I claim as my Invention is manufacturing cocks of glass, crystal,
china, or other silicious materials by casting or moulding their barrels and
plugs at once with their passages or apertures in metal or other suitable
moulds.
In witness whereof, I, the said Pierre Brunon, have hereunto set my
hand and seal, this Twenty-seventh day of April, One thousand eight
hundred and fifty-nine.
