I, CHARLES WILLIAM NEVILLE, of 4, Park Avenue, Saint John's Lane, Bed-
minster, Bristol, Pottery Clerk, do hereby declare the nature of this invention
to be as follows:-
-·
This invention relates to stoneware and other jars and to other vessels having a
projecting "tap-hole," that is to say, a flanged nozzle or socket extending outwards
from the body of the vessel, and consists in improved means for controlling the
drawing off of the contents of such vessels.
According to this invention, a channel is provided in the, under part of the flange
of the "tap-hole" which channel extends from the outer face of the flange into
the bore of the tap hole. The inner orifice of the said channel is normally blocked
by a plug fitted into the bore and capable of being turned therein. The plug is
hollow from its inner end to a determined point towards the outer end at which
said point is an aperture opening to the bore of the tap-hole.
When it is desired to draw off liquid from the vessel, the plug aforesaid is
turned on its axis until the said aperture therein is brought round to the inner
orifice of the channel provided, as aforesaid, in the under part of the projecting
flanged nozzle. The liquid then flows out by the said channel.
To stop the flow, the plug is again turned to its normal position, blocking
outflow through the channel.

Improved Means for Drawing Off Liquids from Stoneware and other
Jars, applicable also to other Vessels.
I, CHARLES WILLIAM NEVILLE, of 4, Park Avenue, Saint John's Lane, Bed-
minster, Bristol, Pottery Clerk, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
66
This invention relates to that kind of jar or vessel which is distinguished by the
term tap-hole," that is to say, jars and like vessels for containing liquids and
having a tap-hole for drawing off the contents.

page_text: According to this invention, a hollow boss or nozzle is incorporated with the
vessel, and a channel for drawing off the contents of the vessel is made in the
under part of the said boss or nozzle which is flanged. This channel extends from
the outer face of the flange of the boss or nozzle into the bore of the tap-hole.
A spigot or plug is fitted into the tap-hole and is capable of being turned therein
about its longitudinal axis. The spigot or plug is open at the inner end and is
hollow for the greater part of its length. It has an outlet orifice provided in its
body. A packing or sheathing of cork or other suitable material may intervene
between the interior of the tap-hole and the outer face of the spigot or plug, and,
in that case, the outlet channel is continued through the packing.
When the outlet orifice of the spigot or plug is brought round to face the inner
orifice of the outlet channel in the flanged projection, communication between the
interior of the vessel and the said channel is established and the contents of the
vessel flow freely out.
The communication is stopped by turning the spigot or plug until the outlet
crifice therein is turned away clear of the inner orifice of the channel in the
flanged boss or projection.
The flanged projection may be situated at any suitable place in the jar or other
vessel. According to one arrangement, the mouth of the vessel serves also as the
tap-hole.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 thereon
represents a vertical section through one side of a tap-hole" jar made in accord-
ance with this invention. Fig. 2 is a plan of the spigot or plug and shows the
cutlet aperture thereof. Fig. 3 is a similar section to Fig. 1 but shows the spigot
or plug in the position it occupies when the communication for outflow or drawing-
off is established.
Projecting from the side of the jar is a flanged boss or nozzle a through which is
provided a passage b extending into the interior of the jar c. c is the jar bottom.
In the passage 6 is inserted the spigot or plug d which is open at the inner end,
is hollow or tubular throughout the greater part of its length and is solid or
closed at its outer end, which latter is shaped as shown and is furnished with a
cross-pin to facilitate turning. Or any other conveniently shaped thumb-
piece may be substituted for the pin d'.
A sheathing of cork or other suitable material intervenes between the spigot or
plug d and the face of the passage b. This packing need not always be used,
but it is preferred. When not used, the spigot must fit the passage it lies in.
In the spigot or plug d is an orifice f. In the lower part of the flanged boss or
nozzle a is a channel y extending from the outer face of the boss into the passage b
which contains the spigot or plug d. When packing or sheathing such as c
is employed, the channel is continued through it, as shown at Fig. 3.
When it is required to draw off liquid from the jar c, the spigot or plug d is
turned to the position shown at Fig. 3. The orifice f in the spigot or plug d
faces the outlet channel g, and the liquid is free to flow out through the said
channel.
The outflow is stopped by turning the spigot or plug d until the orifice f is
turned away clear of the inner orifice of the channel g.
In jars and other vessels made in accordance with this invention, the ordinary
tap is dispensed with, but nevertheless, an ordinary plug tap can be inserted in
place of the spigot or plug d, in an emergency, or at other times as may be
desired.
It will be obvious that the use of this invention is not restricted to stoneware and
other jars, but that it is equally applicable to other vessels, such as glass barrels
and the like.
At Fig. 4 is illustrated a method of wiring the spigot or plug d to the jar so
as to prevent the spigot or plug from being forced out of the jar under pressure
acting from within. The wire is looped around the neck of the spigot or plug d,
and, after having been passed through holes provided in the flange of the boss or

page_text: nozzle a, the wire is looped behind the flange and secured by twisting the ends
together as shown.
At Fig. 5 is illustrated a modification, according to which the mouth of the
jar serves also as the tap-hole. The spigot or plug is fitted into the mouth of the
jar and the outlet channel is made in the nozzle i. When it is required to draw
off liquid from the jar, the latter is laid on its side with the outlet channel down-
wards and the spigot is turned to the proper position for outflow.
When it is required to charge the jar, the spigot is temporarily removed.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In stoneware and like jars and vessels, means for controlling the outflow of
liquid; said means consisting of a spigot or plug such as d with outlet orifice f,
and a flanged boss or nozzle such as a, incorporated with the vessel, and having a
socket into which the spigot or plug is fitted, and an outlet channel such as
extending from the spigot or plug chamber to the outer face of the aforesaid
flanged boss or nozzle, as hereinabove described and shown in the accompanying
drawings.
2. The modification hereinabove described with reference to Fig. 5 of the accom-
panying drawings, under which the mouth of the vessel serves also as the chamber
for the spigot or plug, and the outlet channel is provided in the nozzle surmounting
the neck of the vessel.
