PROVISIONAL SPECIFICATION.
An Improved Apparatus for Purifying and Drying Steam.
I, FRANÇOIS HEUSE, of 18, Rue de Jupille, Bressoux, Liége, in the Kingdom of
Belgium, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for purifying and drying steam whereby the
separation is effected of the water drawn along and the water of condensation and
the said waters can be automatically discharged into the steam generators.
The invention chiefly consists in the combination of a cylindrical vessel provided
with an internal cone in which the water is separated from the steam with a
vessel of suitable shape provided with a float arranged to act automatically
when the water has reached a certain level in the vessel and an injecting
device adapted to the said vessel and designed to discharge the water into the
boiler.
This apparatus comprises the cylindrical vessel in which is placed the cone
provided with perforations and plates. One of the ends of this cone has a wide
mouth at the inlet end of the cylinder vessel whilst the other end is connected in
the form of a tube to a vessel closed at its upper and lower parts by plates connected
together by means of tie rods. In this vessel are arranged two sieves or perforated
plates connected together by bars and supported on the bottom of the apparatus
by means of tie pieces.
Between the said bars which serve as guides is placed the float provided at its
centre with a tube through which is passed a rod terminating at its lower part in
a valve closing the mouth of a pipe.
The float is fixed on the rod by means of a set screw passing through the tube.
The rod is besides arranged to actuate a cranked lever operating a valve which
normally closes the mouth of a pipe opening into the upper part of the vessel.
Beneath the float are arranged two springs designed to counterbalance the pressure
to which the float is subjected when the steam has access to the apparatus. This
pressure can also be counterbalanced by regulating a spring surrounding the
extension of the rod outside the vessel and a spring acting on the end of the said
rod in a protecting casing.
The two pipes, one of which is provided with a cock, are united in such a manner
as to constitute an injector, a suitable stop valve in front of the injector being
provided upon the pipe leading to the boiler.
The apparatus is besides provided with a spring safety valve, a three-way cock
for turning off the water outside the purifier when requiring to repair the same
or after the starting of the engine, and cleaning holes. The rod is guided between
the bars by means of a cross piece of suitable shape.
To make use of the apparatus the springs must be first regulated so as to counter-
balance the pressure exerted by the steam on the float, the apparatus being after-
wards connected to the steam pipes, the water of condensation and the steam will
enter the cone by one end of the cylindrical vessel. Under the action of the plates

page_text: and perforations in the cone the water becomes separated from the steam. The
latter having become dried escapes through the opposite end of the cylindrical
vessel whilst the separated water runs down into the water vessel, passing through
the cock regulated at this moment so as to place the cone in connection with the
vessel. The water thus accumulates in the said vessel the upper part of which is
filled with steam and ends by raising the float. The float in rising carries up the
rod which actuates one valve and the lever controlling the other valve. Conse-
quently the rising of the float effects the opening of the pipes into the water vessel.
The steam escapes through the injector pipe and is forced into the boiler, the water
arriving through the other pipe. The water having been forced into the boiler,
the float descends thereby effecting the closing of the mouths of the pipes by their
respective valves. The perforated plates in the water vessel are designed to prevent
the passage of mud and deposits with which the water of condensation may be
charged.
A safety valve is provided for allowing the water to flow off in case a rush of
water takes place in the apparatus and consequently the passage way of the valve
would be insufficient to ensure the discharge.
When required the flow of the water into the boiler can be stopped by simply
closing the cock on the injector pipe. In like manner, at starting, the flow of
water into the water vessel can be stopped by simply turning off the cock of the
pipe from the cone-vessel.

I, FRANCOIS HEUSE, of 18, Rue de Jupille, Bressoux, Liége, in the Kingdom of
Belgium, Engineer, 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:-
My invention relates to apparatus for purifying and drying steam whereby the
separation is effected of the water drawn along and the water of condensation and
the said waters can be automatically discharged into the steam generators.
The invention chiefly consists in the combination of a cylindrical vessel provided
with an internal cone in which the water is separated from the steam with a
vessel of suitable shape provided with a float arranged to act automatically
when the water has reached a certain level in the vessel and an injecting
device adapted to the said vessel and designed to discharge the water into the
boiler.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which:-
Figure 1 is a vertical sectional elevation of apparatus for purifying and drying
steam constructed according to my invention;
Figure 2 is a plan of the apparatus with the separating vesel removed; and
Figure 3 is an elevation of the said separating vessel.
This apparatus comprises the cylindrical vessel A in which is placed the cone B
provided with perforations and plates b. One of the ends of this cone has a wide
mouth at the inlet end of the cylindrical vessel A whilst the other end is connected
in the form of a tube to a vessel D) closed at its upper and lower parts by plates E

page_text: connected together by means of tie rods F. In this vessel 1) are arranged two
sieves or perforated plates G connected together by bars J and supported on the
bottom of the apparatus by means of bars G¹.
Between the bars J which serve as guides is placed the float K provided at its
centre with a tube K¹ through which is passed a rod N terminating at its lower
part in a valve L closing the mouth of a pipe M.
The float K is fixed on the rod N by means of a set screw passing through
the tube K
The rod N is besides arranged to actuate a cranked lever y operating a valve Z
which normally closes the mouth of a pipe M opening into the upper part of the
vessel D. Beneath the float I are arranged two springs H designed to counter-
balance the pressure to which the float K is subjected when the steam has access to
the apparatus. This pressure can also be counterbalanced by regulating a spring R
surrounding the extension of the rod N outside the vessel D and a spring S acting
on the end of the said rod in a protecting casing U.
The two pipes M and M', one of which is provided with a cock m, are united in
such a manner as to constitute an injector MI, a suitable stop valve W in front of
the injector being provided upon the pipe Q leading to the boiler.
The apparatus is besides provided with a spring safety valve V, a three-way
cock C for turning off the water outside the purifier when requiring to repair the
same or after the starting of the engine, and cleaning holes X. The rod N is guided
between the bars J by means of a cross piece 11 of suitable shape.
To make use of the apparatus the springs H, R, S must be first regulated so as to
counterbalance the pressure exerted by the steam on the float K, the apparatus
being afterwards connected to the steam pipes, the water of condensation and the
steam will enter the cone B at one end of the cylindrical vessel A.
Under the action
of the plates and perforations in the cone B the water becomes separated
from the steam. The latter having become dried escapes, in the direction of the
arrow, through the opposite end of the cylindrical vessel A whilst the separated
water runs down into the water vessel 1) passing through the cock C regulated at
this moment so as to place the cone B in connection with the vessel. The water
thus accumulates in the said vessel the upper part of which is filled with steam and
ends by raising the float K. The float in rising carries up the rod N which
actuates one valve L and the lever y controlling the other valve Z. Consequently
the rising of the float effects the opening of the pipes M, M into the water vessel D.
The steam escapes through the injector pipe M¹ and is forced into the boiler, the
water arriving through the other pipe M. The water having been forced inte
the boiler, the float descends, thereby effecting the closing of the mouths of the
pipes M, M by their respective valves L and Z. The perforated plates G in
the water vessel 1) are designed to prevent the passage of mud and deposits with
which the water of condensation may be charged.
A safety valve V is provided for allowing the water to flow off in case a rush of
water should take place in the apparatus and the passage way of the valve L should
consequently be insufficient to ensure the discharge.
When required the flow of the water into the boiler can be stopped by simply
closing the cock m on the injector pipe. In like manner, at starting, the flow
of water into the water vessel 1) can be stopped by simply turning off the
cock C.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. An apparatus for purifying and drying steam and for automatically discharg-
ing the purified water into the boiler, characterized by a cylindrical vessel provided
with an internal cone having plates and outlet holes for the steam combined
with a vessel provided with a float the action on which of the pressure of the steam
is counteracted by means of suitable springs, the said float acting upon a rod

page_text: automatically controlling, when the water attains a given level in the said vessel,
the opening of two valves, one giving passage to a jet of steam and the other
to the water of condensation, the said valves being arranged upon pipes united
so as to constitute an injector for forcing the water into the steam boiler,
substantially as set forth.
2. In an apparatus such as that claimed in the first claiming clause the arrange-
ment of sieves or perforated plates designed to retain the mud or deposits and
prevent their being forced into the boiler, substantially as set forth.
3. In an apparatus such as is claimed in the first claiming clause the arrange-
ment of a safety valve designed to allow a supplementary discharge of the water
in case of a rush of water, or when the sectional area of the automatic discharge
valve is insufficient to allow of a proper flow, substantially as set forth.
Dated this 24th day of February 1899.
