A COCK OR TAP FOR DRAWING OFF LIQUIDS
Year: 1824

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAD
TAYLOR junior, of Chipping Ongar, in the County of Essex, Gentleman, send
greeting.
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 Twentieth day of November, in the fifth year of His
reign, did, for Himself, His heirs and successors, give and grant unto
me, the said Isaac Taylor, His especial licence, that I, the said Isaad
Taylor, my exors, admors, and assigns, or such others as I, the said Isaad
Taylor, my exors, admors, and 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, my Inven
tion of "A COCK OR TAP FOR DRAWING OFF LIQUIDS;" in which said Letters
Patent there is contained a proviso obliging me, the said Isaac Taylor, by
an instrument in writing under my hand and seal, particularly to describe
and ascertain the nature of my said Invention, and in what manner the
same is to be performed, and to cause the same to be inrolled in His
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said in part recited Letters Patent (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, I, the said
Isane Taylor, do hereby declare that my said Invention is particularly described
and ascertained as follows, that is to say -

page_text: The tap or cock about to be herein described is applicable to the drawing
off of water, steam, beer, wine, spirits, oil, and other liquids; it is attended
with no peculiar difficulty or inconvenience in the use of it, and is less liablo
to leak or to become out of order than any other tap or cock at present in
use for similar purposes. It has also this advantage (namely), that if the
inner diameter of the tube through which the liquid flows is the same as that
of any cock on the common plan, the quantity of liquid flowing in the same
time will be much greater, because the course of the fluid is not obstructed
by a plug.
The Invention consists of a tube made of copper, brass, silver, glass,
earthenware, or any other suitable substance. This tube is closed at one
end and open at the other, and it has one, two, or more perforations, at the
distance of about an inch or more (according to the size of the cock) from
the closed end of the tube. This tube is fitted into a cork, within which it
moves either backwards and forwards, or circulates within it, according to the
purpose for which the cock is intended. Now, if the cock is supposed to be
fixed in the cask or vessel having the tube so placed as that the perforations
before mentioned are beyond the outer surface of the cork, or not far within
it, then the liquid will be retained; but if the tube is driven inwards so far
that the same perforations stand beyond the inner surface of the cork, and
consequently within the cask or vessel, then the fluid therein contained will
flow through the tube until it is again drawn out to its former place. The
corks selected for the construction of the above-described tap or cock should
be such as are free from fissures or scirrhous parts. The tap or cock, as thus
described, may be made up in a variety of modes to suit different purposes,
as for example, the open end of the tube herein-before described may have a
bend downwards in the form most usually adopted for cocks; it may also be
furnished with a projection or handle by which it may commodiously be
moved for the purpose of drawing the fluid; again, the cork, for greater con-
venience and security, may be contained in a socket of brass, or other suitable
substance, which socket containing the cork and the tube as before described,
may be fixed in the cask or vessel in the usual mode, its outer surface being
either drawn-filed (to use a technical phrase), as may have a screw upon it.
This socket may also be furnished with a knob on its outer rim to receive tho
blow of a hammer in fixing the cock in a cask. The small end of the socket
may be perforated in the usual mode to admit the fluid. When the cock is
have a rim or pro-
constructed on the plan now described the tube should
jection at the closed end to prevent it from being drawn out of the cork.
There are various other methods or plans on which the cock or tap invented

page_text: to the wheel at 8; the form of this plug and key may be varied as much as
shall seem desirable for the sake of security. To draw the liquid the key is
inserted at r, and being received by the plug s, the handle of the key is
brought forward, by which the tube is sent back within the socket, as before
described; t is a rib upon the tube, thero being a corresponding projection
within the sheath upon which it rests and works; the samo is on both sides
the rack; these ribs direct and support the tube in its movement.
These descriptions and representations are given to illustrate the nature of
the Invention, which, it is evident, may be accommodated by some variations in
the construction of the accessary parts to all the different purposes to which
taps or cocks are required to be applied.
In witness whereof, I, the said Isaac Taylor, have hereunto set my hand
and seal, this Nineteenth day of January, in the year of our Lord Onc
