Office of the Commissioners of Patents, with his Petition, on the
17th January 1873.-A communication from abroad by Augusto
Goueslain, of Cherbourg, France.
I, WILLIAM Edward Gedge, of No. 11, Wellington Street, Strand,
in the county of Middlesex, Patent Agent, do hereby declare the nature
of the said Invention for "A NEW OR IMPROVED SYSTEM OF OBTURATOR
COCK FOR LIQUIDS, GASSES, AND VAPOURS, AND AN IMPROVED AERATING FAUCET on
VENT PEG OF SIMILAR CONSTRUCTION," a communication to me from abroad
by Auguste Goueslain, of Cherbourg, France, to be as follows:-
On the accompanying Sheet of Drawing Fig. A is a longitudinal
section, drawn full size, of an obturator or stop plate cock for liquids,
made according to this Invention.
Fig. B is a vertical section of a cock for gas made according to this
Invention; Fig. C is an elevation of the same cock for application to
the apparatuses known as harp lights and others of the same.nature.

page_text: Fig. D is a horizontal section of cock for gas; Fig. is am
view of same cock for lustres and other applications.
CASCIAVE
Fig. F is a vertical elevation partly in section of an aerating faucet for
casks and other receivers of liquids.
And Fig. G is a section of same at a, b.
1 indicates the key of the cock; 2, nut acting as stuffing-box gland;
3, stuffing box gland on the rod of the obturator; 4, bottom plate of
stuffing box gland rendering the cock water-tight; 5, double threaded
screw carrying the obturator; 6, obturator fixed on the screw by a
catch; 7, india-rubber washer for obturator joint.
The cock for liquids shown Fig. A gives a complete and instantaneous
obturation or closing, and by the manner in which it is screwed into the
cask prevents any loss of time and of liquid..
In cocks made according to this system grinding is entirely done
away with, no repairs are necessary, and anybody can keep them in
working order.
The object of the bossage made in the manufacture is to prevent any
injury to the interior parts if it is struck. This cock has also the advan-
tage that it cannot open while being screwed into the cask. It also serves
to fix the quantity of liquid run out in a given time being made at a right
angle, which permits its being bored in all its parts. This cock has no
metallic wear; should there be an escape it would only be necessary to
tighten the nut to re-make the joint until the stuffing was completely
worn out, and this will not be until the nut is completely entered into
the body of the cock.
As the key can be removed the cock cannot be opened by unauthorized
persons, and a. broken square half fixed, half loose, may be fitted if
desired to prevent any tampering with the cock by means of nippers.
This system of obturator prevents any twisting of the washer as well in
the gas cocks B, C, D, E, as in the cocks for liquids.
The aerating faucet or vent peg is intended to replace the wooden peg
in ordinary use for stopping the opening giving air to the receiver of
liquid. With this faucet permanently fixed it is only necessary to
unscrew it, its screw being hollowed throughout the entire length of its
screw thread.

page_text: These cocks may be made of any size, of any metal suitable to the
application of the cock, and their shape will vary accordingly as they
are to be used in distilleries, refineries, by dyers for steam, or other
purposes.
