AN IMPROVED COMBINED TEE-PIECE AND VALVE
Year: 1865

page_text: LETTERS PATENT to Charles Johnson, of Oxton, near Birkenhead, in the
County of Chester, Landscape Gardener, for the Invention of "AN
IMPROVED COMBINED TEE-PIECE AND VALVE,"
Sealed the 8th September 1865, and dated the 11th March 1865.
PROVISIONAL SPECIFICATION left by the said Charles Johnson at the
Office of the Commissioners of Patents, with his Petition, on the 11th
March 1865.
I, CHARLES JOHNSON; of Oxton, near Birkenhead, in the County of Chester,
Landscape Gardener, do hereby declare the nature of the said Invention for
"AN IMPROVED COMBINED TEE-PIECE AND VALVE." to be as follows:-
Pipe or tube pieces, which more or less resemble and are known as tees,
have been used to connect pipes or tubes for conveying fluids for different
purposes, and to provide a connection for branches from the said conveyers.
In greenhouses and other places, as means of stopping and directing the flow
of fluids, cocks or valves have had to be affixed near to the said tee-pieces.
From the want of space this in many cases has been inconvenient, besides it
has been attended with considerable expense. My Invention consists in com-
bining a tee-piece and a valve or stop valve in one connected piece, that is,
so arranging or fitting. à valve or plug on a spindle to be operated by a screw,
wheel, lever, or other handle. that it can be made to close against a seating,
and cut off the flow through the "vertical" part of the tee, or can be arranged
to shut off either of the other passages, and direct the flow of fluids through
the said "vertical" part and one of the "horizontal" parts.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JOHNSON, of Oxton, near Birkenhead, in the County of Chester, Landscape
Gardener, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of March, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Johnson, Her special license that I, the said Charles Johnson, my
executors, administrators, and assigns, or such others as I, the said Charles
Johnson, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 COMBINED TEE-PIECE AND VALVE," upon the condition (amongst others)
that I, the said Charles Johnson, 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 Charles Johnson, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Pipe or tube pieces, which more or less resemble and are known as tees,
have been used to connect pipes or tubes for conveying fluids for different
purposes, and to provide a connection for branches from the said conveyers.
In greenhouses and other places, as means of stopping and directing the flow
of fluids, cocks or valves have had to be affixed near to the said tee-pieces.
From the want of space this in many cases has been inconvenient, besides it
has been attended with considerable expense. My Invention consists in com-
bining a tee-piece and a valve or stop valve in one connected piece, that is,
so arranging or fitting a valve or plug on a spindle to be operated by a screw,
wheel, lever, or other handle that it can be made to close against a seating.

to shut off either of the other passages, and direct the flow of fluid through
the said "vertical" part and one of the "horizontal" parts."
The accompanying Sheet of Drawings contains longitudinal sections of two
arrangements of apparatus according to my Invention.
Fig. shows an ordinary tee-piece a with socket ends combined with a
circular flat valve b, arranged to be operated by the spindle c and wheel
lever d. The valve b in this construction can only be made to shut off com-
munication with the vertical branch a¹ of the tee, the other two horizontal
branch a, a, being constantly open to and with each other. Fig. 2 shows
a tee-piece with socketted so-called vertical branch e, and flanged horizontal
branches f, f', combined with a plug-like hollow valve g, arranged to be
moved by the wheel and spindle i in the seating j. Communication can be
made between e and either for fi by raising the valve g until the opening k
therein comes opposite to in the seating i, or k¹ opposite to l¹. To open
communication, however, between and from all the branches it is necessary
to raise the valve by the wheel and spindle à upwards, or beyond both
I and 1.
Having now described the nature and particularized practicable modi-
fications of my said Invention, I would have it understood that I do not
confine myself to the particular details of parts herein mentioned, nor to any
exact shape of parts, so long as the leading features of my Invention are
retained; what I. claim is, the construction of a tee-piece and valve in one
connected piece, operating substantially in the manner and for the purpose
herein described.
In witness whereof, 1, the said Charles Johnson, have hereunto set my
hand and seal, this Ninth day of September, in the year of our
Lord One thousand eight hundred and sixty-five.
In the presence of
JOHN T. KING,
Patent Agent, 4, Clayton Square,
Liverpool.
