IMPROVEMENTS IN JARS OR ANALOGOUS VESSELS FOR CONTAINING ACIDS, SPIRITS, AND OTHER LIQUIDS."
Year: 1876

page_text: LETTERS PATENT to James Storer, of Glasgow, in the County of Lanark,
North Britain, for the Invention of "IMPROVEMENTS IN JARS OR ANALOGOUS
VESSELS FOR CONTAINING ACIDS, SPIRITS, AND OTHER LIQUIDS."
PROVISIONAL SPECIFICATION left by the said James Storer at the Office
of the Commissioners of Patents on the 19th December 1876.
JAMES STORER, of Glasgow, in the County of Lanark, North Britain. "IM-
PROVEMENTS IN JARS OR ANALOGOUS VESSELS FOR CONTAINING ACIDS, SPIRITS, AND
OTHER LIQUIDS."
This Invention, which relates to improvements in jars or analogous vessels for
containing acids, spirits, and other liquids, constitutes a new or improved mouth-
piece and stopper, as herein-after described, for such vessels, and has for its object to
diminish or practically to prevent the loss which takes place when emptying liquids
from such vessels, at the same time to prevent injury to the fingers and clothes of
persons engaged in handling such vessels as are charged with acids or other
corroding liquids.
The Invention consists in forming the screw plug, by which mouth-pieces of such
vessels are closed, with a vertical channel down a portion of one side, cutting
through the lower threads of the screw. The threads at the upper part of the screw
plug are left untouched; this channel is for the purpose of allowing the liquid to be
discharged through and at the side of the plug opposite to the channel herein-before
mentioned; another groove is formed for allowing air to pass into the vessel.
When the plug is screwed down to its seat, which is preferably provided with a
ring of india-rubber or other elastic material, the contents of the vessel are secured
therein, and when it is desired to discharge or empty the liquid from the vessel the
screw plug is turned round until the entire threads at its upper part are screwed
out of the mouth and the heads of the channels are above the mouth, which position
enables one of the channels in the plug to become the orifice of discharge and the
other to become the air entrance.
The mouth-piece is also provided by preference with a lip or spout for directing
the discharge of the liquid.

the said James Storer in the Great Seal Patent Office on the 14th June
1877.
JAMES STORER, of Glasgow, in the County of Lanark, North Britain. "IM-
PROVEMENTS IN JARS OR ANALOGOUS VESSELS FOR CONTAINING ACIDS, SPIRITS, OR
OTHER LIQUIDS."
My said Invention, which relates to improvements in jars or analogous vessels for
containing acids, spirits, and other liquids, constitutes a new or improved mouth-
piece and stoppers for such vessels, and has for its object to diminish or practically
to prevent the loss which takes place when emptying liquids from these vessels, and
at the same time to prevent injury to the fingers and clothes of persons engaged in
handling vessels charged with acids or other corroding liquids.
And in order that my said Invention may be properly understood, I now proceed
more particularly to set forth the system, mode, or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
annexed Sheet of Drawings, and to the letters and figures marked thereon, that is
to say :-
On one Sheet of Drawings hereunto appended the new or improved mouth-piece
and stopper, constructed in accordance with my said Invention, is illustrated under
one arrangement at Figure 1.
The plug or stopper A which is screwed into the mouth-piece B is formed with a
vertical channel a down a portion of one side, and cutting through the lower threads
of the screw, the upper threads being left entire; this channel is for the purpose of
allowing the liquid to be discharged through or at the side of the plug and opposite
to the said channel; another vertical groove or channel b is also formed in the plug
or stopper A to allow air to pass into the vessel whilst the liquid is being
discharged. The stopper A is also formed with a circular or other shaped head C,
provided with holes or openings e to admit of a rod or key being inserted when it
is desired to open the channel, or to close it by screwing the head C down upon the
mouth-piece B, preferably provided with a ring D of india-rubber or equivalent
elastic material.
The mouth-piece B is also provided by preference with a lip or spout Ę for
directing the discharge of the liquid. In discharging the liquid from the vessel the
plug A is screwed round until it is raised to about the position shewn in dotted
lines, and until the vertical channel a is directly in line with the spout E, thus
allowing the liquid to pass up from the interior of the vessel, and out through the
spout, air being at the same time admitted to the interior of the vessel through the
channel b.
Under a modification of this arrangement, and which is shewn at Figure 2 of the
Drawings, the plug A is made with a circular or other shaped channel or passage a
through its interior, from the upper end of which the liquid is discharged into the
spout E, when the plug or stopper is raised as indicated by the dotted lines. The
plug is in this case also provided with a channel or groove b for the admission of
air into the interior of the vessel, and when in its closed position its head may rest
or press upon an elastic ring, as seen at Figure 1, or the said ring may be dispensed
with and the head C screwed down against the mouth-piece itself.
Figure 3 of the Drawings is a plan of Figure 2, shewing the discharge orifice a,
the air passage b, the spout E, and a notch or mark that may be cut or formed in
the head C to enable the person pouring the liquid to know exactly when the
channel a is directly in a line with the spout E.
Figure 4 of the Drawings illustrates another modification of my said Invention
under which the channel or groove a for the liquid, and also the channel or groove b
for the air, are cut through the upper screw threads of the mouth-piece B itself, the
lower threads being kept entire. The threads of the plug in this case are entire, or

page_text: its lower threads may have the air channel b cut in them as at Figures 1 and 2 of
the Drawings.
When it is desired to discharge the liquid in this case the plug A is raised into
the position shewn by the dotted lines, so that the liquid may be allowed to pass
from the interior F of the vessel through the channel a in the mouth-piece B into
the spout E, the air passing into the vessel by the passage b formed also in the
mouth-piece.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or may
be used or practically carried into effect, I would observe in conclusion that what I
consider to be novel and original, and therefore claim as the Invention secured to mo
by the herein-before in part recited Letters Patent is, the new or improved mouth-
piece and stopper constructed as herein-before described and shewn under several
modifications on the appended Sheet of Drawings, by which liquid is or may be
discharged from vessels without removing the stopper or plug.
In witness whereof, I, the said James Storer, have hereunto set my hand and
seal, this Thirteenth day of June, in the year of our Lord One thousand
eight hundred and seventy-seven.
