A HEATER FOR ECONOMIZING FUEL AND WATER FOR HIGH-PRESSURE STEAM ENGINES
Year: 1875

page_text: LETTERS PATENT to Edward Taylor, of No. 20, Saint Mary's Road,
Faversham, in the County of Kent, Millwright, for the Invention'
of "A HEATER FOR ECONOMIZING FUEL AND WATER FOR HIGH-PRESSURE
STEAM ENGINES."
PROVISIONAL SPECIFICATION left by the said Edward Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
10th November 1875.
I, EDWARD TAYLOR, of No. 20, St. Mary's Road, Faversham, in the
County of Kent, Millwright, do hereby declare the nature of the said
Invention for "A HEATER FOR ECONOMIZING FUEL AND WATER FOR HIGH-
PRESSURE STEAM ENGINES," to be as follows:-
Firstly. The heating of the water to be pumped into the boiler by
passing the exhaust steam pipe from the engine through it (instead of
using cold water) to the extraordinary heat of from 180 to 200 degrees,
which is plainly evident that hereby a large quantity of fuel is.
saved.

page_text: Secondly. The passing of the exhaust steam pipe through the cistern
containing the water in such a manner so as not to cause any check to
the engine, but on the contrary to relieve in a very great measure the
internal pressure. This has heretofore been the great objection to the
numerous heaters now in use. This is done by dividing the steam in
the manner shewn on the Drawing into three parts at the inlet by
inserting sharp knife edged plates continued with easy curves into the
two sides and making the centre opening rather smaller than the other
two on account of the increased pressure in the centre. The steam
thus carried through in three pipes gives a large heating surface and is
much relieved by the increased .cubical contents. It is brought out at
the outlet in a chamber, as shewn, containing strainer.
Thirdly. By running the condensed water from the under side of the
heater by the insertion of strainers, as shewn on the Drawing, and in
pipes, and reusing it. Thereby the water is not forced through the
exhaust pipe, causing a check to the engine but is drawn off by pipes.
Where there is a scarcity of water this is an object for consideration;
and the water being pure (condensed) cannot possibly cause a deposit or
incrustation upon the inside of boiler.

Fourthly. The peculiar and novel construction of the strainers, of
which there are two kinds, a long one placed in the bottom of each
pipe (as shown in plan), and perforated at the centres (as shown in
plan), allowing the water to run through the perforations along inside
and ultimately discharging by means of a small pipe into a cistern; the
other is placed in the large outlet where the pipes rejoin; it is in the
form of a louvre, allowing the condensed liquor to run through and
taken away by a pipe. (Both of these will be seen more clearly by
reference to the Drawing.)

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of November, in the
year of our Lord One thousand eight hundred and seventy-six, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Taylor, Her special
licence that I, the said Edward Taylor, my executors, administrators, and
assigns, or such others as I, the said Edward Taylor, 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 "A HEATER FOR
ECONOMIZING FUEl and Water for HIGH-PRESSURE STEAM ENGINES," upon the
condition (amongst others) that I, the said Edward Taylor, my execu-
tors 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 Taylor, 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:-
Firstly. The heating of the water to be pumped into the boiler by
passing the exhaust steam pipe from the engine through it (instead of
using cold water) to the extraordinary heat of from 180 to 200 degrees,
which is plainly evident that thereby a large quantity of fuel is
saved.
Secondly. The passing of the exhaust steam pipe through the cistern
containing the water in such a manner so as not to cause any check to
the engine, but on the contrary to relieve in a very great measure the
internal pressure. This has heretofore been the great objection to the
numerous heaters now in use. This is done by dividing the steam in
the manner shewn on the Drawing into three parts at the inlet by.
inserting sharp knife edged plates continued with easy curves into the
two sides, and making the centre opening rather smaller than the other

carried through in three pipes gives a large heating surface, and is
much relieved by the increased cubical contents. It is brought out at
the outlet in a chamber, as shewn, containing strainer.
Thirdly. By running the condensed water from the under side of the
heater by the insertion of strainers, as shewn on the Drawing, and in

Where there is a scarcity of water this is an object for consideration,
and the water being pure (condensed) cannot possibly cause a deposit or

Fourthly. The peculiar and novel construction of the strainer of
which there are two kinds, a long one placed in the bottom of each
pipe (as shewn in plan), and perforated at the centres (as shewn in
plan), allowing the water to run through the perforations along inside
and ultimately discharging by means of a small pipe into a cistern.
The other is placed in the large outlet where the pipes rejoin; it is in
the form of a louvre, allowing the condensed liquor to run through and
taken away by a pipe. (Both of these will be seen more clearly by
reference to the Drawing.)
In witness whereof, I, the said Edward Taylor, have hereunto
set my hand and seal, this Fourth day of May, in the year.
