AN IMPROVED CONSTRUCTION OF STEAM BOILER
Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
LINTON, of Selby, in the County of York, Brazier, 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 Twenty-ninth day of January, in the third year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
John Linton, His especial licence that I, the said John Linton, my exors,
admors, and assigns, or such others as I, the said John Linton, my exors,
admors, 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, my Invention of "AN IMPROVED CONSTRUCTION
OF STEAM BOILER;" in which said Letters Patent is contained a proviso, obliging
me, the said John Linton, 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
enrolled in His said Majesty's High Court of Chancery within six 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.

marked L are end views of the shallow and comparatively broad horizontal
channels or spaces before alluded to. Figure 3. is a sectional plan of
Figure 1; and as similar letters are used to denote similar parts in all the
Figures, this 'and the next Figure 'will require very little additional descrip-
tion. W is the furnace door; and it will be observed that the top of the
boiler case, with the steam chest and pipe and a part of the top of the flues,
is represented as removed, so as to shew the manner in which the flues open
into the fire box or furnace. This plan also shews the manner in which the
water channels I and J communicate with the vertical channels S, and serve
as ordinary bridges to all the flues. Figure 4 is also a plan of Figure 1, with
the top of the boiler case, the steam chest, and pipe, and portions of the tops of
the flues removed, the better to shew its construction. K, K, K, are the
gutters, forming part of the top of the fire box. D is the vertical part of the
flue which passes into the chimney, and the remaining letters denote similar
parts to those which are marked with similar letters in the other Figures.
Figure 5 is a side elevation of two of my boilers put together, as they would
be used for steam navigation; and Figure 6 is a sectional elevation of a boiler
constructed on my plan, but with three bends instead of two to the flue, and it
is evident the flues may be lengthened in this way to any desired length.
Now, whereas I claim as my Invention the placing a series of flues within
a boiler case in such manner as to form a number of narrow and comparatively
deep vertical, with shallow and comparatively broad horizontal, channels or
spaces between, above, and below the flues, for the water of the boiler to flow
into, in manner herein-before described; and such my Invention being, to
the best of my knowledge and belief, entirely new and never before used within
that part of His said Majesty's United Kingdom of Great Britain and Ireland
called England, His said dominion of Wales, or Town of Berwick-upon-Tweed,
I do hereby declare this to be my Specification of the same, and that I do
verily believe this my said Specification doth comply in all respects, fully and
without reserve or disguise, with the proviso in the said herein-before in part
recited Letters Patent contained; wherefore I do hereby claim to maintain
exclusive right and privilege to my said Invention.
In witness whereof, I, the said John Linton, have hereunto set my hand
and seal, this Twenty-fifth day of July, in the year of our Lord One
thousand eight hundred and thirty-three.
JOHN (L.S.) LINTON.
