page_text: SURREY'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, JAMES
SURREY, of Battersea, in the County of Surrey, Miller, sends greeting.
WHEREAS His present Majesty King George the Fourth, by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Fourth day of September, in the fourth year of His reign, did, for Himself,
His heirs and successors, give and grant unto the said James Surrey His
especial licence that he, the said James Surrey, his executors, administrators,
and assigns, or such others as the said James Surrey, his executors, adminis-
trators, 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, his Invention of "A NEW METHOD
FOR THE APPLYING HEAT FOR THE PRODUCING STEAM, AND FOR VARIOUS OTHER PUR-
POSES, WHEREBY THE EXPENCE OF FUEL WILL BE LESSENED;" in which said Letters
Patent there is contained a proviso obliging the said James Surrey, by an
instrument in writing under his hand and seal, particularly to describe and
ascertain the nature of his 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 recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear..

page_text: NOW THEREFORE BE IT KNOWN, that in compliance with the said
proviso, the said James Surrey doth hereby declare that the nature of his
said Invention, and the manner in which the same is to be performed, is
described and ascertained in the following explanation thereof, that is to say:
The Invention of the said James Surrey consists in bringing into use the
heat extracted from coal in the burning and manufacture of coke, by applying
the same for the production of steam for steam engines, and other purposes, in
manner following, that is to say:-As many coke ovens as may be necessary
by the heat thereof to insure the quantity of steam required being erected in
the usual or any other convenient way, let an artificial search be made in each
as high as the coals when charged, and run on the top of the said artificial
search a rim or curb of iron, or other substance of sufficient thickness to retain
the heat extracted from the coal or coke; then place in each of the said ovens
two tubes or pipes of iron or other metal, one on each side thereof, on the top
of the artificial search, one end of each of the said pipes or tubes to come out at
the front of the oven, with a flange for cleansing, and the other end thereof to
run out at the back or other convenient part of the oven, a sufficient space
being left between the said two pipes or tubes or elsewhere, as convenient, for
the smoke, fire, or heat to escape, instead of coming out at the oven's mouth
or stock; and if the ovens be sufficiently large to admit thereof, without inter-
fering with the burning of the coke, other pipes or tubes may be introduced in
like manner between the coke and the crown of the oven, and the several
pipes or tubes above mentioned must be made to communicate with the main
reservoir or boiler of the engine or other works. The main reservoir or boiler
being charged in the usual way, and so as to keep the before-mentioned pipes
or tubes always full of water, steam will be generated and pass to the main
reservoir or boiler for any purpose required. Care should be taken so to
place the pipes or tubes in the ovens that the draft be not checked, and
that they may be taken out at the front or back of the oven, if required,
and the said pipes or tubes should be independant of the ovens, and be so
placed that the spring of the oven will be behind the saine. The fire in passing
out of the ovens may be directed through a fluc (and which flue may be
conveniently and most beneficially made by carrying over the crown of the oven
ą second crown or arch of iron, brick, or other substance capable of confining
and retaining the heat), and such flue may be filled with other pipes or tubes, to
be so placed as to receive the greatest possible action of the fire passing through the
flue, and the last-mentioned pipes or tubes being also made to communicate with
the general reservoir or boiler, and being kept filled with water, as before men-
tioned, an additional quantity of steam will be generated by means of the same

page_text: fire or heat, and without any additional consumption of fuel. If the flame of
one oven should be found insufficient to consume the smoke of the other, a
damper or register may be used to stop the smoke from passing direct into the
flue, and a communication made from one oven to the other by means by a
pipe or aperture (also with a damper or register) to take the smoke of either
oven alternately through the other when sufficiently hot to consume the same,
thereby ensuring a convenient method of consuming the whole of the smoke,
and converting the same into heat or flame, to be used or applied as before
mentioned.
In witness whereof, the said James Surrey hath hereunto set his hand
and seal, this Third day of November, in the year of our Lord One
thousand eight hundred and twenty-three.
Signed and sealed in the presence of
CHA DRUCE, jun³,
10, Billiter Square, London.
AND BE IT REMEMBERED, that on the same Third day of November,
in the year above mentioned, the aforesaid James Surrey came before our
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and all and everything therein contained, in form above written. And also the
Specification aforesaid was stamped according to the tenor of the Statute in
that case made and provided.
