CERTAIN IMPROVEMENTS IN COCKS FOR DRAWING OFF LIQUIDS
Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ENOCH
WILLIAM RUDDER, of Edgbaston, near Birmingham, Cock Founder, 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 Eighteenth day of January, in the fifth year of His reign,
did, for Himself, His heirs, and successors, give and grant unto me, the said
Enoch William Rudder, His especial licence that I, the said Enoch William
Rudder, my executors, admors, and assigns, or such others as I, the said Enoch
William Rudder, 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 Invention of "CERTAIN IMPROVEMENTS IN COCKS FOR DRAWING OFF LIQUIDS;"
in which said Letters Patent there is contained a proviso, obliging me,
the said Enoch William Rudder, 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 six
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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, tho
said Enoch William Rudder, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are
particularly described in and by the Drawings hereunto annexed, and the
following description thereof (that is to say) :-
The said improvements consist,―
First, in a certain peculiar way or manner of applying cork to the said
cock, in order that those parts thereof which are now fitted and adjusted to
each other by the operation termed tighting, may be fitted or adjusted to each
other by the intervention of the said cork without tighting, and is equally
applicable whether the said cock may be made of metal, wood, horn, bone,
ivory, glass, or other sufficiently strong material, and whether one part be
composed of one material, and another part thereof of another material; and,
Secondly, in the power of applying cork as aforesaid to cocks of other
constructions not herein described, provided the barrel and plug of the same
may be thereby adjusted to each other without the said operation of
tighting.

which the liquor is discharged out of the cock. Fig. 2nd. the barrel pre-
pared to receive a tube or hollow cylinder of cork. Fig. 3d. a section of
the spout, having a screw on the inside to fit the plug, and by which the plug
is drawn down and confined to its place within the said tube or hollow
cylinder of cork. Fig. 4th. the said tube or cylinder of cork. Fig. 5, the
plug, either taper or straight, with a screw on the end, to fit the spout. a,
the water way, terminating at 6, but which may also be made transversely
quite through the plug. Fig. 6, a lock cock. a, the head; b, the barrel;
c, the spout. Fig. 7, a section of the lock cock. a, the barrel with a
screw cut thereon, both at top and bottom; b, the plug, either taper or straight
with a water way, as in the night cock; c, the head, having a male screw
at d, to fit the barrel; e, a spiral spring, by which the plug is forced to its
place or bearing in the cock; f, the spout made fast to the barrel by a screw
at g; h, the cork tube or hollow cylinder of cork; j, a small screw to secure
the head. Fig. 8, the key to turn the cock, where a screw is represented as
cut on the outside, it may be cut in the inside, and where represented on the
inside it may be cut on the outside. The method by which the said hollow
cylinders of cork or cork tubes are prepared and applied is as follows:-I
take a cork of the finest and best quality, a little larger than the inside of
the barrel of the cock, and as round as it can be procured, and, having suffi-
ciently cleared the barrel of all knobs and protuberances, I force or drive the

page_text: "
a hole
cork-into the said barrel, then with a tool which I call a borer; (that is to say),
a small metal tube of a convenient length, either of brass, copper, steel, or
other metal,. and in form similar to p.gun barrel, but not taper, and very thin
and keen, I bore.out the.centre.of.the, cork. Having thus, made
through the cork, but not quite so large, as; the,.plug..of.the.cock, I force
the plug into the said hole, having, previously made the said plug as round
and true as possible, cut or turned either taper or straight, as I think
proper. I.then boil.both barrel, plug, and, cork,,all..together, for about fifteen
minutes. By this operation..the cork, becomes dense, and firm, and by
accommodating itself to the barrel and plug of the cock, renders the operation
of tighting unnecessary. When the whole is cold (not sooner) I take out
the plug, and with another.borer of the same kind passed up the shank of
the cock I make a small transverse hole in the said cork, to correspond with.
the hole or waterway in the plug. Having cut off any uneven or superfluous
parts of the cork I grease the plug, put all the several parts into their
respective places, and screw the cock together. Should the cork, in boiling,
swell, and be thereby-squeezed into the-hole-or-waterway-in-the-plug,-the
waterway may be made after the cork has been boiled, instead of before,
or a round piece of metal, either taper.or, straight, may be used as a false plug
instead of the real one, only not quite so large and without a hole; and when
the whole is cold the false plug may be taken out, and the true-one put into
its place. A small quantity of resin may, if necessary, be applied to the
barrel of the cock or to the cork previous to the boiling, in order to attach
the cork the more firmly to the said cock, and should the cork break in boring
and clog the borer the broken parts of the cork must be pushed out with
a metal pin or rod, for which purpose both ends of the borer are to be
left open, and the handle of the borer to be made hollow. The said cork
tubes may also be prepared thus:-Having procured corks of a proper
size, fix one of them in a lathe, and putting the lathe in motion, gently press.
the before-menotined borer against the centre of the cork, by which the
middle or core of the cork will be taken out and be received into the inside
or cavity of the borer, from whence it may be removed by the metal rod, as
before directed.
Having by such or some other convenient method or methods procured the
said cork tubes, force them into the barrel of the cock, and proceed in the
remainder of the operation as before directed.
Lastly, the said cork tubes may be applied either to the plug or barrel of
the cock. The plug may also be held or confined to its place or bearing
within the said cork tubes or hollow cylinders of cork by various other

page_text: methods now in general use, without departing from the principle of the said
improvements.
In witness whereof, I, the said Enoch William Rudder, have hereunto
set my hand and seal, this Eleventh day of July, in the year of our
Lord One thousand eight hundred and twenty-five.
