IMPROVED APPARATUS FOR HEATING THE FEED WATER FOR STEAM BOILERS, AND IN THE MEANS OR METHOD OF AND APPLIANCE FOR CLEANING FEED WATER HEATING APPARATUS
Year: 1873

page_text: LETTERS PATENT to Robert Sutcliffe, of Castle Mills, Idle, near Leeds,
in the County. of York, Cotton Doubler, for the Invention of
"IMPROVED APPARATUS FOR HEATING THE FEED WATER FOR STEAM BOILERS,
AND IN THE MEANS OR METHOD OF AND APPLIANCE FOR CLEANING FEED
WATER HEATING APPARATUS."
Sealed the 21st November 1873, and dated the 25th September 1873.
PROVISIONAL SPECIFICATION left by the said Robert Sutcliffe at
the Office of the Commissioners of Patents, with his Petition, on
the 25th September 1873.
I, ROBERT SUTCLIFFE, of Castle Mills, Idle, near Leeds, in the County
of York, Cotton Doubler, do hereby declare the nature of the said
Invention for "IMPROVED APPARATUS FOR HEATING THE FEED WATER FOR
STEAM- BOILERS, AND IN THE MEANS OR METHOD OF AND-APPLIANCE FOR CLEANING
FEED WATER HEATING APPARATUS," to be as follows:-
This Invention relates to the construction and arrangement of
apparatus to be employed for heating the feed water for steam boilers,
which I construct of wrought-iron lap-welded tubing, folded and
forming one continuous pipe from entrance to exit; the upper and

page_text: lower portions thereof being curved there is a direct and unimpeded
waterway, so that the water must of necessity circulate throughout the
entire length of the tubing, the latter being arranged within the flue or
flues in a vertical or slanting position with its curved portions nearest
the top and the bottom of the flue or flues.
""
Under the lower portion or folds of the pipe for heating the feed
water I employ another or cleansing " pipe, which by means of tubes
connects the feed water heating pipe with this cleansing pipe, the con-
necting tubes being inserted at the curved portion of the feed water
heating pipe, so that on water or steam from the boiler being forced
through the pipes and tubes the whole will be cleansed and freed from
sediment. Taps for turning or diverting the water or steam are provided.
In lieu of the scrapers and similar appliances heretofore employed for
removing the soot, dust, and other exterior deposit left upon the pipes
of the feed water heating apparatus I employ a steam or air pipe or
pipes, extending over, under, or, along those containing the feed water.
From the steam or air pipes branch other pipes of smaller diameter;
these are perforated and arranged in such position that on steam or
compressed air being discharged through the perforations the blast or
current will remove the soot, dust, or deposit from the feed water
heating pipes.
The steam for supplying the perforated pipes will be taken from the
boiler, and on exposure to the heat within the flue will become super-
heated and so dryer and better adapted for this purpose.
In case air be employed it would be compressed within an air vessel
and subjected to heat during its passage from such vessel to the discharge
nines
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Sutcliffe in the Great Seal Patent Office
on the 25th March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
SUTCLIFFE, of Castle Mills, Idle, near Leeds, in the. County of York,
Cotton Doubler, send greeting.

Letters Patent, bearing date the Twenty-fifth day of September, in the
year of our Lord One thousand eight hundred and seventy-three, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Robert Sutcliffe, Her special
licence that I, the said Robert Sutcliffe, my executors, administrators,
and assigns, or such others as I, the said Robert Sutcliffe, 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
"IMPROVED APPARATUS FOR HEATING THE FEED WATER FOR STEAM BOILERS, AND
IN THE MEANS OR METHOD OF AND APPLIANCE FOR CLEANING FEED WATER
HEATING APPARATUS," upon the condition (amongst others) that I, the
said Robert Sutcliffe, my executors 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 Robert Sutcliffe, 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 and accompanying Sheet of Drawings, that is to
say:―
1 This Invention relates to the construction and arrangement of
apparatus to be employed for heating the feed water for steam boilers,
which I construct of wrought-iron lap-welded tubing, folded and
forming one continuous pipe from entrance to exit; the upper and
lower portions thereof being curved there is a direct and uninterrupted
waterway, so that the water must of necessity circulate throughout the
entire length of the tubing, the latter being arranged within the flue or
flues in a vertical or slanting position with its curved portions nearest
the top and bottom of the flues.
Under the lower portion or folds of the pipe for heating the feed
water Templow another on alaansine ning which live' manna'

this my Invention; Fig. 2 is an end elevation; and at Fig. 3 is a plan
view of the same.
At Fig. 4 is shewn detached view of perforated pipe for cleaning the
apparatus.
A is the inlet pipe through which the water flows from pipe to pipe
throughout the whole series or length of coiled pipes A, A, A; thence
by the curved pipe B to the series of pipes C, C, C; again by way of
the curved pipe D to the series E, E, E, and so on, as indicated by the
course of the arrows throughout the whole series to the outlet pipe F, a
so ensuring a complete circulation of the water.

page_text: At G, G, are shewn the cleaning pipes with connections g, whereby
the sediment may be drawn off and the whole series may be flushed with
water or steam from the steam boiler; H, H, are the perforated pipes
through which steam or hot air is to be discharged on to and along the
several pipes constituting the feed water heater for the purpose of
cleansing the same by such means in lieu of the "scrapers or
similar
apparatus heretofore used for that purpose.

Having thus fully described the nature and
tion, together with the manner in which the
performed, I would remark in conclusion that I claim, the construction
and employment of the apparatus as and for the purpose herein fully
described; and shewn in the Drawings.
In witness whereof, I, the said Robert Sutcliffe, have hereunto
set my hand and seal, this Twenty-third day of March, in the
year of our Lord One thousand eight hundred and seventy-four.
