page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TAYLOR, of Wednesbury, in the County of Stafford, Engineer, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Nineteenth day of July, One thousand eight hundred
and thirty, in the first year of His reign, did, for Himself, His heirs and suc-
cessors, give and grant unto me, the said William Taylor, His especial, full
power, sole privilege and authority, that I, the said William Taylor, my exors,
adiiors, and assigns, and such others as I, the said William Taylor, my exors,
adiiors, or assigns, should at any time agree with, and no others, from time to
time and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend within England, Wales, and the
Town of Berwick upon Tweed, my Invention of "CERTAIN IMPROVEMENTS ON
BOILERS AND APPARATUS CONNECTED THEREWITH, APPLICAPLE TO STEAM ENGINES AND
OTHER PURPOSES;" in which said Letters Patent is contained a proviso that I,
the said William Taylor, shall cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, to be
inrolled in His Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Taylor, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following description thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say:―
My Invention consists, first, in improvements applied to a boiler, for the
purpose of applying the water thereto; secondly, in an improvement whereby
the deposition of sediment in boilers may be got rid of whilst the boiler is at
work; and, thirdly, in improvements applied to the furnace and chimney,
whereby I am enabled more perfectly to burn the smoke. I will now proceed
to describe the Drawing hereunto annexed, in which is represented a means of
carrying each of my said improvements into effect.
DESCRIPTION OF THE DRAWING.
Fig. 1 represents a longitudinal section of what I call the water supply
vessel, it being the vessel into which the water first enters prior to its being
admitted into the boiler; this Figure also shows part of the section of a boiler
for the purpose of shewing the manner of applying the water supply vessel to a
boiler. A is the water supply vessel; B, the boiler; C, the water pipe which
descends from the vessel A into the boiler; and it is by this pipe C that the
boiler is supplied with water from the vessel A. D is a pipe ascending from
the top of the boiler into the vessel A, which pipe is for the purpose of convey-
ing steam from the boiler to the top or above the surface of the water contained
in the vessel A, the purpose of which will hereafter be more particularly
described. E is a cock on the pipe C, and F is a cock on the pipe D, which
cocks are opened and shut by the handles e and f, in each of which handles
there is a slit cut for receiving and permiting to slide a stud fixed on the rod
of the float which regulates the quantity of the water supplied to the boiler. G
is the float, and II the rod ascending therefrom. I is a pipe by which the water
supply vessel is filled, either by means of a pump or from a reservoir, on which
pipe I there is a valve M, opening inwards, as shewn in the Drawing. Having
now described the various parts represented in this Figure, I will describe the
manner of their action; in doing which I will suppose that the water has been
forced or flowed into the vessel A, and that that vessel is full; such being the
case, when the water line in the boiler becomes lowered the float G will follow,
and by means of the rod II will draw down the handles e and f of the cocks E
and F placed on the pipes C and D, by which means the steam will be permitted to
flow up the pipe D to the top of the vessel A, which will equalize the pressure in the

page_text: vessel A and the boiler B, when the water will descend through the pipe C into
the boiler, till the level of the water in the boiler has arrived to the proper
height, which will raise the float G, and close the cocks E and F. I would
here observe that when the pressure of the steam is acting in the vessel A, the
valve M will be closed, and thus prevent the water being driven out at the pipe
I; but so soon as the cocks E and F are closed the pressure of the steam will
be stopped in the vessel A, and thus permit the water to flow into and again
fill this vessel. Having now described the first part of my Invention, would
have it understood that what I claim is the application of a separate vessel,
similar to that described as the water supply vessel A, when the water is
supplied therefrom by the steam from the boiler being permitted to flow into
and equalize the pressure, and thus allow the water to flow into the boiler, as
above described. I will now describe Fig. 2 and 3, which represents a means
of getting rid of the deposition or sediment whilst the boiler is working. Lis
the boiler, and M is a recess or smaller vessel connected to the bottom or lower
part of a steam boiler in the manner shewn in this Figure. N is a pipe
connected to the vessel M, having a stop valve or cock thereon; so it will be
evident that as the deposit will be continually taking place in the vessel M, if
the cock of the pipe N is opened, the pressure in the boiler will force out such
deposit or sediment through the pipe and valve N, and thus may the deposit be
got rid of from time to time. I would here observe that the vessel M should
always be placed in such a position as at all times to contain the coldest
particles of the water, which in boilers having the firo within them will always
be at the bottom, as is shown in the Drawing; but in boilers where the fire is
made to act on the outer surface of the bottom of the boiler, the vessels M must
be placed on each side of the boiler, and protected from the action of fire,
as it is necessary that the vessels M should at all times contain the coldest part
of the water of the boiler. Now I would have it understood that I am aware
that boilers or salt pans have been made with troughs or vessels protected from
the action of the fire, and thereby such troughs or vessels contain the coldest
part of the matters boiled in such vessels, but I lay no claim to such salt pans or
boilers for making salt when so constructed, they being already known. But
what I claim is, the application of the vessel M and the valve or cock N to the
boilers of steam engines for the purpose of getting rid of the sediment in the
manner above described, and which as aforesaid forms the second part of my
Invention. Fig 2 and 3 also show part of my improvements in the apparatus
applied to a furnace of a steam boiler; L being the boiler; P, P, the flues, passing
through and around the boiler; Q, the chimney, which is closed at the top. Ris
an outlet placed at some distance from the top of the chimney. S is a pipe con-

page_text: nected to the top of the chimney, which pipe S descends to an exhausting and
blowing apparatus, having a valve placed at the lower end opening into the
cylinder of the blowing apparatus. V is a pipe leading from the exhausting and
blowing apparatus W through the ash pit and into the recess, or well formed
under the bars at the fire-place at X, which recess or well is shown as constructed
of fire bricks, and is open at top into the fire-place, whereby it is at all times
filled with coals, and at the bottom it is sufficiently open to permit of the ashes
being raked out, but which ashes are always to be kept sufficiently above the
opening at the bottom of the well X to prevent the smoke which is forced
through the pipe V being driven in any other direction than upwards through
the burning coal, as will be fully described hereafter. Having now described
the parts represented in this Figure, I will proceed to describe the manner of
their action. The fire being lighted, the smoke will pass along the flues P, P,
and thence into the chimney Q, from whence it would pass out into the atmo-
sphere through the outlet R, but that it is prevented by the working of the
exhaustion and blowing apparatus W, which will cause the smoke to pass
through the pipe S into the cylinder W, whenever the piston in such cylinder
is raised, and the return stroke of the piston will force the smoke so withdrawn
from the chimney through the pipe V, into and through the burning coal, and
thus will the smoke be continually forced through the fire; but in order to
have a continued action of the blowing apparatus in withdrawing and forcing the
smoke it will either be necessary to have two cylinders working in succession,
or to have a closed cylinder, the pipes S and V being connected with the top
and bottom of such cylinder, as is well understood in making exhausting and
blowing apparatus. It will be necessary here to observe that as the black and
dense smoke is only evolved at and a short time after the putting on of fresh
coal, it will only be necessary to work the exhausting and blowing apparatus so
long as such dense smoke is evolved; this apparatus must therefore be attached
to the engine in such a manner as readily to be put into and out of geer, and
when disconnected from the engine sufficient draft will be kept up by the
outlet R, but in case there be a feeding apparatus applied to the furnace,
whereby a continuous supplying of coals is kept up, then the exhausting
and blowing apparatus should be kept in continued action. Fig. 4 shews
another plan of consuming the smoke in furnaces, and consists in passing a
pipe or pipes through the heated coal in such a manner that the smoke evolved
must pass through such heated pipes, and thus will the smoke be consumed.
Y, Y, Y, are three pipes open at their ends Z, Z, Z, being opened for the
passage of the smoke and heated air, which not being able to find vent at any
other part of the furnace are obliged to pass down through the pipes Y, Y, Y,

page_text: which being red hot destroys the smoke, but sufficient draft is kept up for the
fire by the other ends of the pipes Y, Y, Y, being open to the chimney, as
shewn in the Drawing. Now I would have it understood that what I claim
as this third part of my Invention is, the application of an exhausting and
blowing apparatus to the chimney (such chimney being open to the atmosphere),
for the purpose of withdrawing the smoke therefrom and forcing it again
through the fire, as above described; and I also claim the passing of a pipe or
pipes, in the manner above described, through the burning coal, whereby the
smoke evolved by such coal shall, from having no other vent, be obliged to pass
through such heated pipes, and thus destroy or burn the smoke so evolved.
In witness whereof, I, the said William Taylor, have hereunto set my
hand and seal, this Seventeenth day of January, in the year of our
Lord One thousand eight hundred and thirty-one.
