page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
STOCKER and ALEXANDER STOCKER, both of the Parish of Yeovil, in the County

WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-sixth day of January, in the tenth year of His
reign, did, for Himself, His heirs and successors, give and grant unto us, the
said George Stocker and Alexander Stocker, His especial licence that we, the
said George Stocker and Alexander Stocker, our exors, adñors, and assigns,
For such others as we, the said George Stocker and Alexander Stocker, our
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times 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, our Invention of "A COCK FOR
DRAWING LIQUOR FROM CASKS, WHICH PRODUCES A STOP SUPERIOR TO THAT WHICH
IS EFFECTED BY COMMON COCKS;" in which said Letters Patent is contained a
proviso obliging us, the said George Stocker and Alexander Stocker, by an
instrument in writing under our hands and seals, or the hand and seal of one
of us, particularly to describe and ascertain the nature of our said Invention,
and in what manner the same is to be performed, and to cause the same to
be,inrolled in His said Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said recited Letters Patent,

page_text: as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with, the said proviso, we, the said
George. Stocker and Alexander Stocker, do, hereby declare the nature of our
said Invention to consist in causing the passage for the liquor through the
cock, commonly called the way of the cock, to be opened or shut by means
of a conical plug, rising from or descending into, as the case may be, a conical
part of the said passage, or way; and in further compliance with the said
proviso, we, the said George Stocker and Alexander Stocker, do hereby
describe the manner-in-which-our-said-Invention is to be performed, by the
following description thereof, reference being had to the Drawing annexed, and
to the letters marked thereon; that is to say:-
DESCRIPTION OF THE. DRAWING.
The Drawing represents a section of a cock or tap on our plan. A, B, C,
äs the passage for the liquor or way of the cock. B is that part of the way
which is made conical. D is the conical plug fitting into the upper part of
the conical' passage B, so that as the-plug wears it may. continue to.approach
the diminishing end of the conical passage, when shutting off the liquid, and
thus always stop tight. I prefer this plug to be made of wood; and: believe
yew to be the best, but it may of course! be made of metal, leather; or any a
other suitable composition, provided the substance used for the plug. be softer
than that of the conical passage into which it fits." EE; is a socket 'or
cylinder with a double screw worm cut in it to receive the arins r,r, which are
wrought on the shank of the plug. The parts marked Grepresent the ordinary
washers to keep the liquid from rising into the key chamber. K is the key,
and it is hardly necessary to state that in order to shut the passage:for the
liquid the plug-must be screwed down tight into the, conical part:B, by means
of the key, and in order to open it the plug,must be raised by turning the, key
in the reverse direction. !
Now whereas we claim as our Invention.the.method herein-before, described s
of opening and shutting the passage for the liquid or way of the cock by means
of the conical plug D, and the conical part B of the passage A; B; C.. And
such our Invention-being, to the best of our knowledge and belief; entirely new,
and never used within that part of His Majesty's United Kingdom, of.Great
Britain and Ireland called England; His said-Dominion of Wales, or Town of s
'Berwick-upon-Tweed; we do hereby-declare this to-be-our: Specification of 'the
same, and that we do verily believe this our said: Specification doth 'comply, in
all respects, fully-and without reserve or-disguise; with the proviso in the said

page_text: herein-before in part recited Letters Patent contained; wherefore we do hereby
claim to maintain exclusive right and privilege to our said Invention.
In witness whereof, we, the said George Stocker and Alexander Stocker,
have hereunto set our hands and seals, the First day of March, in
the year of our Lord One thousand eight hundred and thirty.
