I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention relates to ordinary boilers used for the generation of steam, and it
has for its object a novel method of constructing such boilers and apparatus connected
with them, so that the steam produced is dry and in the best condition for use, and
so that any incrustation or deposit of substances contained in the feed water and
separated by the evaporation is automatically removed.
In order to put the invention in operation, a cylindrical boiler fired below is used
and is arranged so that the axis is inclined one end being lower than the other. In
the ends of the boiler are fixed two central bearings in which revolve axles which
support a second cylindrical internal boiler. One of these axles passes through the
end of the outer boiler and has fixed upon it a crank or lever. By moving the
latter backward and forward, the inner cylindrical boiler is also moved like a pendulum
upon its axis. The upper part of this inner boiler is provided with an aperture which
allows the steam produced in the space between the two boilers to pass into the
inner one and to return from the latter and pass to the steam pipe.
Upon the lower part of the inner boiler is arranged the mechanism for removing
the incrustation or deposit, consisting of two bars parallel to the axis of the boilers.
These bars are moveable for a sufficient distance round bolts parallel to them and
passing through projections upon the bars, the bolts themselves being carried at the
end of a sufficient number of transverse levers which are arranged in the space
between the bottoms of the two boilers, and turn at their centres upon a longitudinal
axle or centre carried by the inner boiler.

page_text: If now the inner boiler is moved and made to oscillate backward and forward by
the crank already described, the edges of the longitudinal bars which are made angular
and sharp slide over the inner surface of the boiler and remove and agitate the inud.
The bars and also the bolts, axle, and bearings also operate as agitators and prevent
the formation and crystallizing of incrustation. The mud sinks to the bottom of the
outer boiler and being constantly agitated moves slowly toward the lower end and to
an opening provided there.
To this opening a pipe is connected provided with a sliding valve communicating
with an enlarged chamber having a discharge cock or valve.
If the slide valve is opened, the mud will pass into the chamber and by closing the
slide valve and opening the discharge cock, the mud will be entirely removed.

heated by the heat of the water in the hottest part of the boiler, and condensation
of the steam is consequently prevented. The water space between the two boilers
being narrow a very rapid evaporation takes place and only a short time is necessary
to generate steam.
In order that the bars by which the deposit is removed as already described, may
work freely when scraping the boiler, the ends of the transverse levers to which they
are pivotted are made at such an angle below, that the corresponding faces of the
bars come in contact with them and they thus serve to limit the degree to which the
bars can turn, the edges of the latter working freely against the boiler in both
directions, the bars turning somewhat upon their pivots at each end of their stroke
backward and forward.
To allow the heads of rivets to pass, the bars may be provided with grooves or
notches.

A communication to me from abroad by EMIL MORITZ HEIBER, of Breslau, in the
Empire of Germany.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of Middlesex,
do hereby declare the nature of this 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 drawing (that is to say) :-
This invention relates to ordinary boilers used for the generation of steam, and it
has for its objeet a novel method of constructing such boilers and apparatus connected
with them, so that the steam produced is dry and in the best condition for use, and
so that any incrustation or deposit of substances contained in the feed water and
separated by the evaporation is automatically removed.
In order to put the invention in operation, a cylindrical boiler A fired below is
used and is arranged so that the axis is inclined one end being somewhat lower than
the other.
In the ends of the boiler are fixed two central bearings B, B¹, in which revolve
axles which support a second cylindrical internal boiler C. One of these axles B
passes through the end of the outer boiler A and has fixed upon it a crank or lever D.
By moving the latter backward and forward, the inner cylindrical boiler is also
moved like a pendulum upon its axis.
The upper part of this inner boiler C is provided with an aperture O which allows
the steam produced in the space between the two boilers A and C to pass into the
inner one and to return from the latter and pass to the steam pipe.
Upon the lower part of the inner boiler Cis arranged the mechanism for removing
the incrustation or deposit, consisting of two or more bars a parallel to the axis of
the boilers A and C.
These bars a are moveable for a sufficient distance round bolts 6 parallel to them
and passing through projections a¹ upon the bars a, the bolts 6 themselves being
carried at the end of a sufficient number of transverse levers c which are arranged
in the space between the bottoms of the two boilers A and C, and turn at their centres
upon a longitudinal axle d or centre carried by the inner boiler by means of jointed
supports e.
If now the inner boiler C is moved and made to oscillate backward and forward
by the crank D already described, the edges of the longitudinal bars a, which are
made angular and sharp, slide over the inner surface of the boiler and remove and
agitate the mud,

page_text: The bars a as well as the bolts b, axle d and bearings or supports e also operate as
agitators and prevent the formation and crystallizing of incrustation. The mud sinks
to the bottom of the outer boiler A and being constantly agitated moves slowly toward
the lower end and to an opening E provided there.
To this opening a pipe F is connected provided with a sliding valve G communi-
cating with an enlarged chamber H having a discharge cock or valve J.
If the slide valve G is opened, the mud will pass into the chamber H and by
closing the slide valve and opening the discharge cock the mud will be entirely
removed.
An important part of the invention consists in the arrangement of the inner
boiler C. Through the opening O already mentioned in the upper part of this
boiler C, the steam produced in the space between the two boilers A and C passes
into the inner one C. Here it is heated by the heat of the water in the hottest part
of the boiler A and condensation of the steam is consequently prevented.
The water space between the two boilers A and C being narrow a very rapid
evaporation takes place and only a short time is necessary to generate steam.
In order that the bars a by which the deposit is removed as already described, may
work freely when scraping the boiler, the ends of the transverse levers c to which they
are pivotted are made at such an angle below, that the corresponding faces of the
bars a come in contact with them at c¹ or c² and they thus serve to limit the degree to
which the bars can turn, the edges of the latter working freely against the boiler A in
both directions, the bars a turning somewhat upon their pivots at each end of their
stroke backward and forward.
To allow the heads of rivets to pass, the bars may be provided with grooves or
notches as shewn at n in figure 1.
To remove easily water produced by condensation of the steam or accidentally
introduced in any way into the inner boiler C a syphon tube S is provided passing
through the hollow axle B, through which syphon S the water, contained in the
boiler C is removed by the pressure of the steam therein.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The arrangement of an inner cylindrical boiler C in an inclined outer cylindrical
boiler A, the former turning like a pendulum around its axes B, B¹, and being
provided with the levers c c carried by supports e.
2. In the said arrangement, the bars a, swinging around bolts & supported by the
levers c, having grooves or notches n to allow them to pass the rivets and moving
and agitating the mud contained in the feed water and thus preventing deposit or
incrustation.
3. In the said arrangement the opening E at the lower end of the boiler A, con-
nected to a pipe F fitted with sliding valve G, enlarged chamber H and having
discharge cock J for removing the mud.
4. In the said arrangement, the arrangement and use of a syphon pipe S passing
through the hollow axle B of the boiler C into the interior of the latter for removing
any water therein produced by condensation or introduced in any way.
All substantially as set forth and represented in the accompanying drawing.
