Office of the Commissioners of Patents on the 21st December 1882.
GEORGE TEIDEMAN of Lancaster Street in the County of Surrey,
MENTS IN COCKS OR VALVES,"
IMPROVE-
This Invention has for its object improvements in cocks or valves applicable for
water steam gas or other fluid and is specially applicable for use where the cock or
valve leaks or requires repairs, same being offected according to this my Invention
without interfering with the cock or valve-In carrying out my Invention, I
proceed mainly as follows:-The plug of the cock or valve may be formed or con-
structed in the ordinary way with a lining or liner or false plug between the body
and the said plug.-The liner or false plug is formed with suitable openings corre-
sponding with the plug and also openings at the lower part, at right or other
angles with that in the plug, corresponding with those in the body.-The cock or
valve works and is effectuated in the ordinary way-When however from leakage
or otherwise the plug or valve is withdrawn, the false plug or liner is also turned,
thus opening communication with the lower oponing in the liner, and the cock or
valve is worked in same way as with the plug, which when re-inserted and the
false plug turned, communication is again effected through the plug of the cock or
valve. The Invention is also applicable to three or four way cocks or valves, all
that is required being the adjusting of the openings in the plug and false plug at
their proper angles and position. The liner can be adjusted by screw or otherwise
to the required openings or portways-The "liner" may be used as a stop should a
leakage occur without the lower opening for cocks or valves.

MENTS IN COCKS OR VALVES
This Invention has for its object improvements in cocks or valves applicable for
water, steam, gas, or other fluid, and is specially applicable for use where the cock
or valve leaks or requires repairs, same being effected according to this my
Invention without interfering with the service of the cock or valve.
In carrying out my Invention I proceed as follows:-
The plug of the cock or valve may be formed or constructed in the ordinary
way with a lining or liner or false plug between the body and the said plug-The
liner or false plug is formed with suitable openings corresponding with the plug
and also openings at the lower part at right or other angles with that in the plug,
corresponding with those in the body.-The cock or valvo works and is effectuated
in' the ordinary way. When however from leakage or otherwise the plug or valve
is withdrawn, the false plug or liner is also turned, thus opening communication
with the lower opening in the liner and the cock or valve is worked in same way
as with the plug, which when re-inserted and the false plug turned, communication
is again effected through the plug of the cock or valvo.-The Invention is also
applicable to three or four way cocks or valves, all that is required being the
adjusting of the openings in the plug and false plug at their proper angles and
position. The liner can be adjusted by scrow or otherwise to the required openings
or portways. The liner may be used without the lower opening as a stop for cocks
or valves, should a leakage occur
In order that my Invention may be clearly understood, I now proceed to further
describe same by reference to the accompanying drawings, in which Figs. 1, 2,
and 3 show various forms of valves with. liner constructed according to my
Invention

page_text: the grooves or recesses a in the body of the cock or valve the liner being cushioned
on to the packing.
In all these Figures, the same letters indicate corresponding parts.
A represents the valve-B, liner-C, handle or lever attached to liner for
actuating samo-The handle may be dispensed with.
In Figs. 1, 4, 5 and 6, the liner B is shown adapted to a down screwed valve,
the water or other liquid or gas passing through the ways as shown by dotted
lines AB in Fig. 1.-When the liner B is turned, the lower port E is opened to tho
passage, the upper port F being closed by the liner.-In Fig. 2, the liner B is
shown adapted with plug G.-The action is similar to Fig. 1, the adjustment being
effected from the bottom at H.
Fig. 3 shows application of liner B to stop cock, also Figs. 7 and 8 show appli-
cation as in Fig. 3, Fig. 7 being a screw down valve, and Fig. 8 ordinary plug
valve. In all these Figs, the liner B can be adjusted by the handle C, or as in
Fig. 2, from the bottom.
The liner B shown in Fig. 19 is packed as shown at J, so as to have secure
seating when other part or parts are being repaired, and prevent escapo or leakage
through the liner or case.
Although the handle or lever for actuating the liner is shown horizontal, it can
it is evident be applied vertically or in other position.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed or carried out in
practice I claim the Invention of "Improvements in cocks or valves substantially
as herein before set forth and described, wherein the particular point or feature is
the application of adjustible liner or false plug to cocks or valves, substantially as
shown and described.
In Witness whereof I the said George Teideman have hereunto set my hand
and seal this twenty first day of June one thousand eight hundred and
night thron
