Year: 1785

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, JAMES TATE,
of Mill Street, Hanover Square, in the County of Middlesex, Ironmonger,
send greeting.
WHEREAS His most Sacred Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Second day of November, in the twenty-sixth year of His
reign, did give and grant unto me, the said James Tate, my exors, adiňors,
and assigns, special licence, that I, the said James Tate, my exors, admors,
and assigns, during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my "NEW-INVENTED COCK OR VALVE FOR ALL SORTS
OF VESSELS;" in which said Letters Patent there is contained a proviso, that if
I, the said James Tate, should not particularly describe and ascertain the
nature of my said Invention, and in what manner the same was to be per-
formed, by an instrument in writing under my hand and seal, and cause the
same to be inrolled in His Majestie's High Court of Chancery within one
calendar month next and immediately after the date of the said Letters
Patent, that then the said Letters Patent should determine and be void, as by
the said Letters Patent, relation being thereunto had, may more fully appear.

page_text: NOW KNOW YE, that in compliance with and in pursuance of the said
proviso in the said in part recited Letters Patent contained, have in the
margin of these Presents, or hereunto annexed, set forth Drawings of my said
Invention in Figure 1; and I have also, by several other Drawings in the
margin of these Presents, or hereunto annexed, set forth a Drawing of the
several component parts of my said Invention; and I, the said James Tate,
by the Instrument in writing under my hand and seal, do ascertain and more
particularly describe the nature of my said Invention in the said Letters
Patent mentioned and declared, in manner herein-after mentioned, that is
to say :-
I cause a barrel of my new-invented cock or valve to be made or cast of
brass, or any other metal, for the reception of the key or plug, and in the form
described in the aforesaid Drawing of my Invention, as Figure 2, and I
cause a screw to be made at the top of the said barrel, and on the outward
side thereof, as described as Figure 3 in my said Drawing, in order to act
with the cap to be fixed thereon, as herein-after described; and I cause a cap
to be screwed or soldered on the said barrel at the foot of that part thereof
which contains the key to prevent the fluid leaking from the barrel, and which
said last-mentioned cap I cause to be screwed on the inside of the said barrel,
whereby such screw does not appear on the external part of the barrel, such
barrel being thereby apparently only one piece. I then cause a key to be
made for the aforesaid barrel, as described in Figure 4 of my said Drawing,
and I cause a bead to be made round the said key about an inch from the top
thereof, for the cap herein-after described to rest up, and which bead is
described as Figure 5; and I cause the distance between the said bead and
the end of the lower part of the key to correspond with. the depth of the
barrel made for its reception, but I cause. the key to be made rather too large
for the barrel, whereby, when it is first introduced into the barrel, the bead
before-mentioned is left about a quarter of an inch above the barrel, in order
to admit of its being pressed lower as the key shall wear away. I then cause
à cap to be made, as described in Figure 6 of my Drawing, with an opening
to admit the key through the same; and I cause a screw to be made on the
inside of the cap to act on the screw, described at Figure 3, which said last-
mentioned cap, resting on the bead of the key before mentioned, will, when
the same is turned, press down the key into the barrel from time to time, as
such key will wear, and by such pressure always keep the key in close contact
with the barrel and prevent any leakage of the fluid. And I cause such
cap to be fixed upon the key before the crutch or head of the key is
soldered on. And I, the said James Tate, do hereby declare, that I mean and

page_text: intend that the aforesaid Drawings shall be taken as part and parcel of these
Presents.
In witness whereof, I, the said James Tate, have hereunto set my hand and
seal, this First day of December, in the twenty-sixth year of the reign
of our Sovereign Lord George the Third, by the grace of God of Great
Britain, France, and Ireland King, Defender of the Faith, and so
forth, and in the year of our Lord One thousand seven hundred and
eighty-five.
Inrolled the First day of December, in the year of our Lord One
thousand seven hundred and eighty-five.
