CERTAIN IMPROVEMENTS IN APPARATUS APPLICABLE TO STEAM BOILERS OR GENERATORS
Year: 1866

page_text: LETTERS PATENT to Samuel Turton, of Heaton Norris, in the County of
Lancaster, Engineer, for the Invention of "CERTAIN IMPROVEMENTS IN
APPARATUS APPLICABLE TO STEAM BOILERS OR GENERATORS."
Sealed the 23rd November 1866, and dated the 2nd June 1866.
PROVISIONAL SPECIFICATION left by the said Samuel Turton at tho
Office of the Commissioners of Patents, with his Petition, on the
2nd June 1866.
I, SAMUEL TURTON, of Heaton Norris, in the County of Lancaster, Engineer,
do hereby declare the nature of tho said Invention for "CERTAIN IMPROVE-
MENTS IN APPARATUS APPLICABLE TO STEAM BOILERS OR GENERATORS," to be as
follows:-
My Invention relates to apparatus for supplying boilers with water at a point
above the furnace crowns, and also for removing impurities and dirt from the
water in the boiler to prevent incrustation and to assist in its removal.
The improvements consist in a novel arrangement of apparatus, wherein the
dirt discharging or surface "blow-out" apparatus is combined with and forms
part of the water-supply apparatus, and such combined apparatus is to bo
placed above the furnace or flue tube crowns, and below the low-water line of
internally or externally fired boilers.

page_text: The apparatus consists of a tube or pipe extending inside the boiler from
the front plate towards the opposite end of the boiler, and on the upper
surface of this pipe a series of troughs or channels are formed, which collect
or receive the dirt from the water; these troughs are connected with the pipes
by perforations; the end of this pipe passes through the front plate, and a two-
way tap is attached thereto, one duct of which admits water into the tube and
supplies the boiler through the perforations, and when blowing off the accu-
mulated dirt a back pressure valve closes the water supply pipe, when the
other duct of the two-way tap is opened, and the pressure in the boiler forces
the dirt from the trough through the perforations and out of the tap, and thus
the same apparatus is adapted to supply water and to discharge dirt.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Turton in the Great Seal Patent Office on the
28th November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
TUNTON, of Heaton Norris, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of June, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Turton, Her special licence that I, the said Samuel
Turton, my executors, administrators, and assigns, or such others as J, the
said Samuel Turton, 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 "CERTAIN
IMPROVEMENTS IN APPARATUS APPLICABLE TO STEAM BOILERS OR GENERATORS,"
upon the condition (amongst others) that 1, the said Samuel Turton, 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.

page_text: NOW KNOW YE, that I, the said Samuel Turton, 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:-
My Invention relates to apparatus for introducing feed water into boilers,
and also for collecting and carrying off the scum or dirt which collects upon
the surface of the water in a boiler, and may be said to consist of an improved
method of arranging such apparatus so as to combine in one and the same.
apparatus an effectual means of performing both these operations. To effect
this I use a tube or pipe, or series of tubes or pipes extending within the
boiler from the front plates towards the other end, the end of the pipe at the
further end of the boiler being blanked up. In connection with this pipe or
formed upon it is a trough or a series of troughs, which communicate with
the interior of the pipe or tube by means of perforations. This apparatus is
so fixed that the troughs may be a little below the surface of the water, and
may be above the furnace or flue tube crowns in boilers where such exist. In
connection with this pipe I use a tap having three branches, to one of which
is connected the water supply pipe, another is connected to the pipe leading
within the boiler, and the third is connected to the blow-out pipe, and this tap
is so arranged that when the plug is turned in one direction it opens a com-
munication from the water supply pipe to the perforated pipe within the
boiler, and thus admits the water which rises through the perforations and
troughs; but when the plug is turned in the opposite direction it opens a
communication between the perforated pipe in the boiler and the blow-out
pipe, and the surface water with the dirt and impurities floating upon it is
forced down the troughs and through the perforations and pipe and down the
blow-out pipe by the pressure in the boiler; thus the same pipe which at
one time is used for introducing and distributing the water at another_time
is used for carrying off the accumulated dirt and scum from the surface, and
both these operations are performed with one and the same tap or valve. The
feed water in rising through the perforations and troughs cleanses them from
any dirt or scum which may remain in them after blowing out, and the appa-
ratus being fixed above the furnace or flue tube crowns prevents any danger
of injury to the furnace tubes arising from leakage at the valve or tap during
the night, or from the tap or valve being left open and the furnace crowns
laid bare and overheated.
In order to further explain my Invention I proceed to describe the annexed
Drawings, which illustrate the method I prefer to adopt as being the best
means that I am acquainted with for putting my Invention into practice.

is a longitudinal section of the same. The same letters refer to corresponding
parts in all the Figures.
A, A, A, is the shell of the boiler; B, B, B, is the water supply pipo; C
is a back pressure valve; D is the tap with three branches; E, E, is the pipe
or pipes with the perforations opening into the troughs F, F; these troughs
and the pipes are fixed in their position by eye bolts G, G; H is the blow-out;
pipe. I prefer to make the pipe in convenient lengths bolted together.
Figs. 3 and 4 are enlarged views of one of these lengths, Fig. 3 being a
transverse section, and Fig. 4 a longitudinal section. E is the pipe, and F
the trough, which I prefer to cast in one piece with the pipe; I, I, I, are the
perforations opening from the trough into the pipe; K, K, are the flanges at
either end of each length, by means of which they are bolted together.
Having thus fully described my Invention, and the mode of putting the
same into practical effect, I would remark that I claim as my Invention an
apparatus which combines within itself a means of introducing the feed water
and also blowing out the scum and surface dirt, and the arranging of such
apparatus so that it can be commanded by one tap or valve, these two
operations having formerly required separate apparatus with separate taps or
valves.
In witness whereof, I, the said Samuel Turton, have hereunto set my
hand and seal, this Twenty-seventh day of November, in the year of
our Lord One thousand eight hundred and sixty-six.
SAMUEL TURTON. (L.B.)
