Rochdale, in the County of Lancaster, Cotton Spinner, for the Invention
of "AN IMPROVED MODE OF AND APPARATUS FOR HEATING WATER OR OTHER
FLUIDS." A communication from abroad by Jérôme Eugène Tourné, of
New Orleans, in the State of Louisiana, United States of America.
Sealed the 14th January 1862, and dated the 17th July 1861.
PROVISIONAL SPECIFICATION left by the said Joseph Heape Butterworth
at the Office of the Commissioners of Patents, with his Petition, on the
17th July 1861.
I, JOSEPH HEAPE BUTTERWORTH, of Vicar's Moss Mills, Rochdale, in the
County of Lancaster, Cotton Spinner, do hereby declare the nature of the said
Invention for "AN IMPROVED MODE OF AND APPARATUS FOR HEATING WATER OR
OTHER FLUIDS," being a communication to me from abroad by Jerôme Eugene
Tourne, of New Orleans, in the State of Louisiana, United States of America,
to be as follows:-
The Invention relates to the novel employment and use of a metal or alloy,
fusible at a low temperature, for the purpose of retaining heat imparted thereto
by fire, and in applying the heat so obtained to the heating of water or other
fluids. The apparatus consists in a vessel or receptacle furnished, with an
arrangement of internal tubes similar to a multitubular boiler, around which
the fusible metal is disposed, and is heated to produce heated water in the
tubes, and which, when once in a state of fusion, may be kept heated at. a

page_text: minimum consumption of fuel. The water to be heated is circulated through
the tubes and becomes either generated into steam or simply heated, as may
be required, the object being to economize fuel by maintaining the heat, once
sufficiently obtained to liquify the metal, by keeping such molten metal at a
certain heat around the water tubes, which may be effected by a small amount
of fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Butterworth and Henry Heape Butterworth, both of
Rochdale, in the County of Lancaster, Cotton Spinners, Executors
appointed under the last Will and Testament of the said Joseph Heape
Butterworth, deceased, in the Great Seal Patent Office on the 16th
January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BUTTERWORTH and HENRY HEAPE BUTTERWORTH, both of Rochdale, in the
County of Lancaster, Cotton Spinners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of July, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto Joseph
Heape Butterworth, of Vicar's Moss Mills, Rochdale, in the County of Lan-
caster, Cotton Spinner, Her special license that he, the said Joseph Heape
Butterworth, his executors, administrators, and assigns, or such others as he,
the said Joseph Heape Butterworth, his 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 "AN
IMPROVED MODE OF AND APPARATUS FOR HEATING WATER OR OTHER FLUIDS,'
being a communication to him from abroad by Jerôme Eugene Tourne, of
New Orleans, in the State of Louisiana, United States of America, upon the
condition (amongst others) that he, the said Joseph Heape Butterworth, his
executors, or administrators, by an instrument in writing under his, 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 per-
formed, 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
"

page_text: Patent And whereas the said Joseph Heape Butterworth departed this life
on or about the Eighth day of November, One thousand eight hundred and
sixty-one: And whereas by the last will and testament in writing of the said
Joseph Heape Butterworth, bearing date the Twenty-fifth day of January,
One thousand eight hundred and fifty-six, the said Joseph Heape Butterworth
appointed the said John Butterworth and Henry Heape Butterworth executors
of his said will.
NOW KNOW YE, that I, the said John Butterworth, one of the executors
of the said Joseph Heape Butterworth, deceased, do hereby declare the nature
of the said Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement in
writing, and on reference to the accompanying Drawings (that is to say):-
The. Invention relates to the novel employment and use of a metal or alloy,
fusible at a low temperature, for the purpose of retaining heat imparted thereto
by fire, and in applying the heat so obtained for the heating of water or other
fluids. The apparatus consists in a vessel or receptacle furnished with an
arrangement of internal tubes similar to a multitubular boiler, around which
the fusible metal is disposed, and is heated to produce heated water in the
tubes, and which, when once in a state of fusion, may be kept heated at a
minimum consumption of fuel. The water to be heated is circulated through
the tubes and becomes either generated into steam or simply heated, as may
be required, the object being to economise fuel by maintaining the heat, once
sufficiently obtained, to liquify the metal by keeping such molten metal at a
certain heat around the water tubes, which may be effected by a small amount
of fuel.
In order that the Invention may be better understood reference is here
made to the accompanying Sheet of Drawings, in which different forms of
apparatus for effecting the object of the Invention are shewn, the course of
the water or other liquid being clearly indicated by the arrows.
Fig. 1 represents a longitudinal section of one form of the heater, in which
the tubes a, a, a, are shewn surrounded by the metal occupying the spaces b, b, b,
the said tubes extending directly from end to end of the case or receptacle;
Fig. 2 shews an arrangement in which the tubes form circuitous passages for
the purpose of increasing their heating surfaces; Fig. 3 shewing a modification
of the same, in which separate sets of tubes are arranged in the same heater,
the chambers c, c, forming communications between the different sets of tubes
in such a manner as to cause the water to follow a circuitous course in its
passage through the heater, the effect being the same as in the arrangement
represented in Fig. 2; Figs. 4 and 5 are sections of Fig. 3 taken on the dotted

page_text: lines at each end; and Fig. 6 is a sectional view of an arrangement in which
a number of heaters, each filled with the metal or alloy, and containing a set
of tubes, are heated by one furnace.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim the application and use of a metal or an alloy of
metals in a molten state to retain heat with a minimum amount of fuel for
the purpose of heating water and other fluids by passing the same through
tubes or passages immersed in or in contact with the molten metal.
In witness whereof, I, the said John Butterworth, have hereunto set my'
hand and seal, this Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-two.
JOHN BUTTERWORTH. (L.S.)
