page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
SMITH, of Droitwich, in the County of Worcestor, Civil Engineer, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth did,
by His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Nineteenth day of June, 1828, in the fourth year
of His reign, give and grant unto me, the said James Smith, my exors,
admors, and assigns, His especial licence, full power, sole priviledge and
authority, that I, the said James Smith, my exors, admors, and assigns, 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, and also in all His Majesty's Colonies and Plantations abroad, my
Invention of "AN APPARATUS FOR THE APPLYING STEAK TO THE BOILING AND
CONCENTRATION OF SOLUTIONS IN GENERAL, CHRYSTALISING THE MURIAT OF SODA
FROM BRINES CONTAINING THAT SALT, MELTING AND REFINING OF TALLOW AND
OIL, BOILING OF BUGAR, DISTILLING, AND OTHER SIMILAR PURPOSES;" in which said
Letters Patent there is contained a proviso that if I, the said James Smith,
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in writing
under my hand and seal, and 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 Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, shall utterly

page_text: cease, determine, and become void, as in and by the same, relation being
hereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Smith, do hereby declare the nature of my said Invention to consist
in a new manner of constructing a steam boiler with a flat and extended top
or upper surface, and in performing the various operations set forth in my
said herein-before recited title to my said Patent on the top or upper surface
of such boiler as aforesaid; and in further compliance with the said proviso,
I, the said James Smith, do hereby also describe the manner in which I
perform my said Invention by the following description thereof, reference being
had to the Drawings and figures annexed thereto, that is to say :-
The Drawing represents a cross section of my said apparatus. A is my
said steam boiler, having a flat top or upper surface C; and in order to give
the required strength to a boiler of this shape, I tie the top and bottom of the
same together by bolts, as shown in the Drawing. The fire is applied to the
bottom of this boiler B in any of the ordinary ways now in use. C, which is
the top of the boiler A, is also the bottom of the pan or vessel required to
perform the various operations set forth in my said herein-before recited title
to my said Patent. P. P, aro projecting sides to the same, and are par-
ticularly useful in the evaporation of all saline solutions, because by this
arrangement the edges of the pan are kept cooler than all the other parts
of it, and the fluid is not only thus prevented from boiling over, but the salt
as it forms is thrown by the ebulition upon this projecting part, and less
incrustation is formed at that part of the bottom of the pan which is more
immediately acted upon by the steam when my said apparatus is to be set to
work. Water should be introduced into the boiler by means of a funnel and
feed pipe F, to the depth of about two inches. g is a guage cock by which
to ascertain when the water attains that depth. S is a cock for the purpose
of drawing off the water again when occasion shall require; and e is a
cock for giving vent to the rarified air when necessary; V is a safety valve.
By this arrangement it will be seen that fire being applied to the bottom of
the boiler A, steam will be generated and distributed over the whole of the
bottom of the pan above it. The fluid in the pan being exposed to the
atmosphere will always be sufficiently cool to cause a condensation of the
steam below on the bottom of the pan, which will find its way again in the
form of water to the bottom of the boiler, there again to be converted into
steam, by reason of which the water in the boiler will very seldom require to
be replenished. This boiler is formed of plates of metal rivetted together at
the edges in the usual way. for making boilers. And as to the general

page_text: dimensions of my said apparatus, I have found the following answer perfectly
for the purpose of evaporating brines, that is to say:-The boiler to be
nine inches deep, twelve feet wide, and 50 feet long. The pan to be the same
length as the boiler, but to project 18 inches wider at each side of the boiler.
The pan to be 12 inches deep, the bottom and sides of the boiler, and the sides
of the pan, to be a quarter of an inch thick, and the bottom of the pan or top of
the boiler to be ths of an inch thick. The bolts which tie the top and bottom
of the boiler together should be about six inches apart from each other through-
out the whole boiler, and should themselves be about 4ths of an inch thick..
Now these pans herein-before described as used for the evaporation of brines
may require some slight alteration in form or additional strength when used
for the boiling of sugar, or for the melting and refining of whale or other
oil or tallow, or for distilling or other purposes to which they may be found
applicable; but a steam boiler so constructed as aforesaid, and a pan or other
vessel so arranged on the top or upper surface of such boiler as aforesaid,
for the purpose set forth in the herein-before recited title to my said Patent,
being to the best of my knowledge and belief entirely new, and never before
used in these Kingdoms, nor in His said Majesty's Colonies nor Plantations
abroad, I do hereby declare this to be my Specification of the same, and
that I do verily believe this said Specification doth comply in all respects fully
and without reserve or disguise, with the said proviso in the said in part recited
Letters Patent contained; and I do hereby therefore propose to maintain my
exclusive right and privilege to my said Invention.
In witness whereof, I, the said James Smith, have hereunto set my hand
and seal, this Tenth day of December, in the year of our Lord One
thousand eight hundred and twenty-three.
