page_text: LETTERS PATENT to John Musgrave, the younger, of the Globe Iron
Works, Bolton-le-Moors, in the County of Lancaster, Ironfounder, for
the Invention of "THE APPLICATION OF THE HEAT FROM THE FURNACES OF

PROVISIONAL SPECIFICATION left by the said John Musgrave at the
Office of the Commissioners of Patents, with his Petition, on the
31st March 1858.
I, JOHN MUSGRAVE, the younger, of the Globe Iron Works, Bolton-le-
Moors, in the County of Lancaster, Ironfounder, do hereby declare the nature
of the said Invention for "THE APPLICATION OF THE HEAT FROM THE FURNACES
OF SINGEING OR DRESSING PLATES TO GENERATING STEAM AND DRYING PURPOSES,
AND IMPROVEMENTS IN THE CONSTRUCTION OF SUCH FURNACES," to be as follows:--
The flues of the furnaces of singeing or dressing plates have heretofore
been in direct communication with the chimney, consequently the products
of combustion after heating the said plates were wasted.
My Invention consists in applying these products of combustion to heat
or to assist in heating a boiler for generating steam or a drying apparatus.
My improvements in the construction of the furnaces of singeing or dress-
ing plates consist in surrounding or partially surrounding the fire grates or
flues of such furnaces with water chambers, or placing such fire grates within
a small steam generator to absorb and apply beneficiallya portion of the heat
required for heating the plate.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MUSGRAVE, the younger, of the Globe Iron Works, Bolton-le-Moors, in the
County of Lancaster, Ironfounder, send greeting.
WHEREAS Her most excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself. Her heirs and successors, give and grant unto me, the
said John Musgrave, Her special licence that I, the said John Musgrave, my
executors, administrators, and assigns, or such others as I, the said John
Musgrave, my executors, administrators, 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 "THE APPLICATION OF
THE HEAT FROM THE FURNACES OF SINGEING OR DRESSING PLATES TO GENERATING
STEAM AND DRYING PURPOSES, AND IMPROVEMENTS IN THE CONSTRUCTION OF SUCH
FURNACES," upon the condition (amongst others) that I the said John
Musgrave, myexecutors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain thenature of the said Iuvention, 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 John Musgrave, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say)
:-
The flues of the furnaces of singeing or dressing plates have heretofore
been in direct communication with the chimney, consequently the products
of combustion after heating the said plates were wasted.
My Invention consists in applying these products of combustion to heat or
to assist in heating a boiler for generating steam or a drying apparatus.
My Improvements in the construction of the furnacesofsingeing or dressing
plates consists in surrounding the fire grates or flues of such furnaces with
water chambers, or placing such fire grates within a small steam generator

page_text: to absorb and apply beneficially a portion of the heat required for heating
the plate.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the means pursued by me,
reference being had to the accompanying Drawings, and to the figures and
letters marked thereon.
-
On Sheet 1, Figure 1 represents a longitudinal elevation, partly in section,
of a singeing or dressing apparatus, showing how the products of combustion
requisite to heat the plates may be applied to generate steam. Figure 2 is
a transverse section through the line A, A, on Figure 1; and Figure 3 is
another transverse section through the line B, B, on Figure 1.
In Figures 1 and 2, a, a, are two singeing or dressing plates similar to
those usually employed by bleachers to "fire" or burn the loose fibres from
cotton or other fabrics; these plates are heated to a red or nearly red heat
by the products of combustion passing along the flue b, the fire for heating
the singeing or dressing plate is usually placed directly under or at one end
thereof, and the flue has heretofore been in direct communication with the
chimney, consequently the products of combustion after heating the plate
were wasted.
My Invention consists in economizing fuel by applying these products
of combustion to generate steam or to drying purposes in the following
or any other convenient manner :-c is a short cylindrical boiler furnished
with a flue d containing the fire grate e; the boiler c is in front of the
plates a, a, and beyond them is placed another boiler f, which is also
furnished with an internal flue g and external flues k. Each of the boilers c
and fis furnished with a steam dome, and, these domes are in communication
with each other by the pipe h; the lower parts of the boilers are connected
by the pipes i, i, by these means a constant circulation of the steam and
water is kept up. When the fire is lighted on the grate e, the products of
combustion heat the water in the boiler c, then passing through the flue b,
impart the requisite heat to the plates a, a, and then passing through the
flues g and communicate the remaining heat to the boiler before entering
the flue leading to the chimney l. In some cases the front part of the boiler
marked c may be dispensed with and only the part f employed, and in other
cases the heated products of combustion from the flue b may be conveyed
to an apparatus for heating air or water for drying purposes.
I
On Sheet 2, Figure 4 is a longitudinal elevation, partly in section, of a
modification of my Invention; Figure 5 is an end elevation.of the same.
a, a, are the singeing or dressing plates; b, the flue under them; c, a short

page_text: cylindrical boiler, which is furnished with two tubes c', c', forming the sides of
the fire grate e; fis a vertical boiler placed beyond the plates a, a; this
boiler is connected to the steam dome of the one marked c by the pipe h, and
the pipes i, i, are for the circulation of water, as described in reference to
Figures 1, 2, and 3. Various other modifications might be shown, but the
foregoing are sufficient to illustrate this part of my Invention.
The second part of my Invention is shown in Figure 6, which represents
a transverse section of a furnace for heating, singeing, or dressing plates, the
sides of which are formed by the water chambers m, m; these chambers are
connected at each end with a boiler or otherwise, as is found most con-
venient, the object of the side chambers being to absorb and apply beneficially
the heat which would otherwise be wasted. It is evident that my improve-
ments may be applied and used in combination with tubular or multitubular
boilers, and that the water chambers may also be considerably modified in
shape and position.
Having thus stated the nature of my Invention and particularly described
the means of carrying the same into operation, I declare that I claini,―
First, the application of, the products of combustion from the furnaces of
singeing and dressing plates to heat or to assist in heating steam boilers or
drying apparatus, as described.
Secondly, the combination of steam boilers and singeing or dressing plates,
as described.
And, lastly, the application of water chambers to the furnaces of singeing
or dressing plates, as described.
In witness whereof, I, the said John Musgrave, the younger, have
hereto set my hand and seal, this Ninth day of September, in the year
of our Lord One thousand eight hundred and fifty-eight.
