Year: 1869

page_text: LETTERS PATENT to Edward Crowe, of Middlesbrough-on-Tees, in
the County of York, for the Invention of "IMPROVEMENTS IN APPLYING
THE WASTE HEAT FROM REVERBERATORY FURNACES TO THE GENERATION OF
STEAM."
Sealed the 25th September, 1869, and dated the 29th April 1869.
PROVISIONAL SPECIFICATION left by the said Edward Crowe at the
Office of the Commissioners of Patents, with his Petition, on the
29th April 1869.
I, EDWARD CROWE, of Middlesbrough-on-Tees, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN APPLYING THE WASTE HEAT FROM REVERBERATORY FURNACES TO THE
GENERATION OF STEAM," to be as follows:-
This Invention has for its object improvements in applying the waste
heat from reverberatory furnaces to the generation of steam. For this
purpose I mount on the top of the reverberatory furnace, it may be a
puddling furnace or other such like furnace, a boiler consisting of two
horizontal tubes arranged one over the other, and connected by a
Price 8d.1

page_text: number of upright tubes arranged at short distances apart along the
horizontal tubes. The water line of the boiler is at the diameter of the
upper tube or thereabout, and the boiler below this line is enclosed in a
chamber of brickwork, into which at one end the products from the
furnace enter, and which at the other end is connected with the
chimney so that the chamber is in fact the flue of the furnace. The
sides of the chamber at the level of the vertical tubes are corrugated so
as alternately to approach and recede from the vertical tubes, so that the
draught is caused to pass in an undulating direction; this causes it to
impinge more effectually on the vertical pipes, and at the same time
sufficient space is obtained for a man to pass through the chamber to
clean it from time to time. The feed water is introduced into the
lower tube of the boiler at the cooler end of the chamber. There is a
steam dome on the upper tube and other ordinary boiler fittings are
provided.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Crowe in the Great Seal Patent Office.
on the 29th October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, EDWARD
CROWE, of Middlesbrough-on-Tees, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Edward Crowe, Her special licence that I,
the said Edward Crowe, my executors, administrators, and assigns,
or such others as I, the said Edward Crowe, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN APPLYING THE WASTE HEAT
FROM REVERBERATORY FURNACES TO THE GENERATION OF STEAM," upon the con-
(lition (amongst others) that I, the said Edward Crowe, my executors

page_text: or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Crowe, do hereby declare
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
The
This Invention has for its object improvements in applying the waste
For
heat from reverberatory furnaces to the generation of steam.
this purpose 1 employ a boiler consisting of two horizontal tubes
arranged one over the other, and connected by a number of upright
tubes arranged at short distances apart along the horizontal tubes.
water line of the boiler is at the diameter of the upper tube or there-
about, and the boiler below this line is enclosed in a chamber of brick-
work into which at one end the products from the furnace enter, and
which at the other end is connected with the chimney so that the
chamber is in fact the flue of the furnace. The sides of the chamber
at the level of the vertical tubes are corrugated so as alternately to
approach and recede from the vertical tubes, so that the draft is caused
to pass in an undulating direction; this causes it to impinge more
effectually on the vertical pipes and at the same time sufficient space
is obtained for a man to pass through the chamber to clean it from
time to time. The feed water is introduced into the lower tube of the
boiler at the cooler end of the chamber. There is a steam dome on the
upper tube and other ordinary boiler fittings are provided.
In the Drawing hereunto annexed I have shewn a horizontal section,
longitudinal section, and cross section of a boiler constructed and
mounted in the manner above described. a, a, are the horizontal tubes
of the boiler connected to one another by upright tubes b; c is the
chamber of brickwork within which the boiler is enclosed; c¹ are the
corrugations in the sides of the chamber, at the level of the vertical
tubes; the arrangements of these corrugations is clearly shewn by the
horizontal section. The sides of the chamber are supported by angle
bars d tied together at top and bottom by tie bars as shewn. The
manner of supporting the boiler within the brickwork chamber is clearly

page_text: shewn by the Drawing; the manner in which the sides of the chamber
are supported by angle bars d tied together at top and bottom by tie
bars is also clearly shewn.
The horizontal tubes of the boiler have
each at one end a man-hole e fitted with a suitable cover, so that each
tube can readily be cleaned; f is a man-hole to afford access to the
interior of the chamber c. The waste gases from a furnace are by a
suitable flue led into the chamber c through the opening at its end,
and after traversing the chamber in a zig-zag course they pass away
by the chimney g.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is, the applying the waste heat from reverberatory furnaces to the
generation of steam, by means of apparatus substantially such as is
herein described.
In witness whereof, I, the said Edward Crowe, have hereunto set
my hand and seal, this Twenty-sixth day of October, in the year
of our Lord One thousand eight hundred and sixty-nine.
E. CROWE. (L.S.)
