page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
Cook, of Redcross Square, Cripplegate, in the City of London, Fireworker,
send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventh day of September, in the first year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
William Cock, His especial licence, sole privilege and authority, that I, the
said William Cock, my executors, administrators, and assigns, or such others
as I, the said William Cock, my executors, adiñiors, 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 mentioned, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "CERTAIN IMPROVEMENTS ON COCKS FOR SUPPLYING KITCHEN RANGES
OR COOKING APPARATUS WITH WATER, AND FOR OTHER PURPOSES, TO BE CALLED
FOUNTAIN COCKS;" in which said Letters Patent is contained a proviso, that I, the
said William Cock, shall cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled in
His Majesty's High Court of Chancery within six calendar months next after
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto bad, will more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Cook, do hereby declare the nature of my Invention, and the manner
in which the same is to be performed, are particularly described and ascer-
tained by the following description thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):-
:-
My improvements relate to supplying water to boilers of ranges or cooking
apparatus, and other boilers which are used for heating water, where part of the
heated water is occasionally withdrawn and the supply required to be continally
kept up. Now, the object of my Invention is the construction of cocks in such
a manner that the turning of tho handles of such cocks shall open the water-
way, whereby the heated water may be withdrawn, and by having a doublo
way in the plug and barrel of such cock, the cold waterway will be opened
into the boiler, and these two ways being adjusted to each other, the boiler will
always be supplied with an equal quantity of water to that which is withdrawn,
and thereby doing away with the danger of the bursting of the boiler, from the
circumstance of the supply of water becoming low; for by the application of
cocks with my improvements applied thereto, the boiler must at all times be
properly supplied with water, and at the time of withdrawing of the water
which has become heated, so that the water-mark or height of the water in
the boiler will never vary. But in order that my Invention may be fully
understood, I will describe the Drawing hereunto annexed, which represents a
section of part of a boiler with one of my improved cocks applied thereto.
Figure 1 represents a section of the cock and the other parts connected
therewith.
Figure 2, an end view of the cock, which shows the hot water way, and also
two cold water supply ways.
Figure 3 shows the plug separately. In each of these Figures the same
letters indicate similar parts; a being the plug; b, the hot water way; and c, a
pipe connected therewith; d cold water supply pipe, leading from a tauk or
reservoir, from whence the supply of water to tho boiler is obtained; this pipe d
leading to the cold water way e, and thence to the waterway f, when the plug
is turned for the purpose of withdrawing hot water.
Figure 4 is a section of the cock for the purpose of showing the cold water-
ways e and f.
Having now described the various parts, I will suppose that a quantity of
hot water is to be withdrawn, by which I shall be able to trace the action
which will take place in all the parts. The cock is represented as being
opened for the passage of the water which will flow down the pipe c into the

page_text: waterway b, at the same time the cold water will descend from the supply
tank by the pipe d into the cold water way e, and thence through the plug into
the waterway into the boiler, and thus the boiler at all times will be supplied
with a quantity of water equal to that which is from time to time withdrawn,
and the hotter part of the water will at all times be taken away, in consequence
of the pipe c ascending to just below the water line in the boiler, and the
water can never be drawn through the cock unless the water line be above the
pipe c. Now it will be evident that the cold water way should at all times be
less than the hot water way in proportion to the altitude of the tank from which
the water is supplied to compensate for the downward pressure of the column
of water, and also to compensate for the expansion of tho water when in
bented state; and it is also evident that this arrangement of the supply may be
varied; in the present instance the cold water supply pipe is made to pass
through the boiler, but it may be made to pass direct to the cock; and it will
be further evident that this arrangement may be applied to all sorts of boilers
where the changing of the water therein is desired, as above described.
Having now described the various parts of my Invention, and the manner
of using the same, I would have it understood that what I claim is, the
constructing of cocks in the manner above described, and applying the same
to the supplying of water to kitchen ranges and cooking apparatus, and
to other purposes.
In witness whereof, I, the said William Cook, have hereunto set my
hand and seal, this Seventh day of March, in the year of our Lord Ono
