Year: 1875

page_text: LETTERS PATENT to Benjamin Clifford Sykes, of Cleckheaton, in the
County of York, M.D, for the Invention of "IMPROVED APPARATUS
FOR HEATING WATER."
Scaled the 11th January 1876, and dated the 16th July 1875.
PROVISIONAL SPECIFICATION left by the said Benjamin Clifford Sykes
at the Office of the Commissioners of Patents, with his Petition;
on the 16th July 1875.
I, BENJAMIN CLIFFORD SYKES, of Cleckheaton, in the County of
York, M D., do hereby declare the nature of the said Invention for
"IMPROVED APPARATUS FOR HEATING WATER," to be as follows :—
This Invention relates to the manufacture and use of apparatus for
purpose aforesaid of simple and inexpensive construction, and is more
especially designed for application to and as forming the back boiler of
kitchen fire-grates, and is mainly intended for heating water for domestic
purposes.
I employ a bent, curved, or coiled pipe (or pipes) preferably of
copper, which is or are enclosed in metal, by preference cast iron, the

page_text: whole being of outward shape or figure as to form the back of the fire-
grate The terminations of the coiled or bent pipes are the entrance
and exit ways for the water, which is heated during its passage or
circulation through the pipe or pipes.
When enclosing the pipe or pipes in, say for instance, cast iron, I
find it desirable to cause a flow of cold water through the pipe or pipes
to preserve them from the action of the extreme heat of the melted
metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Clifford Sykes in the Great Seal Patent
Office on the 15th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
CLIFFORD SYKES, of Cleckheaton, in the County of York, M.D., send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Ierself, Her heirs and successors, give
and grant unto me, the said Benjamin Clifford Sykes, Her special licence
that I, the said Benjamin Clifford Sykes, my executors, administrators,
and assigns, or such others as 1, the said Benjamin Clifford Sykes, 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, usc,
exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVED APPARATUS FOR HEATING WATER," upon the condition (amongst
others) that I, the said Benjamin Clifford Sykes, my exccutors
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 Lotters Patent.

circulation therethrough, and it will be understood that two or more of
such heating apparatus may be connected by pipe, as at J, and used so
as more effectually to utilize the heated gasses from the fuel; examples
are given by Figs. 3 and 4, the heated gas passing in the direction
shewn by arrows. At L and M are plates employed for supporting the
opposite ends of the plates C, D, and also admit of slight movement,
compensating for expansion and contraction.
When enclosing the curved pipes by casting iron or other metal
around such pipes, see Fig. 6, a flow of water through the pipes A
should be maintained so as to protect the pipes from the excessive heat,
but I prefer the plates cast separately and secured by rivets d as above
doscribed.
Having thus fully described the nature and particulars of this my
said Invention, together with the manner in which the same is to bo or
may be carried into practical effect, I would have it understood I lay no
claim to the use of a curved pipe or pipes as a medium for heating
water, nor do I lay claim to the construction or to any of the parts
composing the stoves or grates shown in the Drawings, such being
introduced only for the purpose of illustrating the application of my
Invention, which I declare to be and claim as consisting of the com-
bination of the coiled or curved pipe or pipes A and B with the plate C,
or plates C and D, for the purpose herein fully described.
In witness whereof, I, the said Benjamin Clifford Sykes, have
hereunto set my hand and scal, this Eleventh day of January,
in the year of our Lord One thousand eight hundred and
soventy-six.
