An Improved Combined Steam Separator and Expansion Connection.
I, HORACE EDWARD BALY of 4 Soane Street Ipswich in the County of Suffolk
Engineer, do hereby declare the nature of this invention to be as follows:-
This is a class of Steam Separator more especially adapted for steam pipes.
between the generators and the motive power Engines, and is used for extracting
the superfluous moisture from the steam, so that practically, dry steam passes to
the Engine, it has combined with it an expansion connection, so as to prevent
broken pipes and leaky joints.
One way
propose making this separator, is by flanging two circular plates to
a hat shape form, the two flanges coming together form a receiver, between these
two flanges, I insert a flat circular plate or diaphram, and all three plates are
rivetted or bolted together. The crowns of the two hat shaped plates are flat, and
on the centre of these crowns are fixed the inlet and outlet steam pipes, holes being
cut in the crowns to suit the required size of pipes. A hole or perforation is made
in the top of the diaphram plate, so that when the steam enters the separator, it
impinges against the Diaphram, and then takes an upward course, and passes
through the hole or perforations in the diaphram, and down again to the outlet
pipe.
The crowns are made of a flexible material and may either be flat or corrugated
the corrugations running concentric with the centre of the crowns in such away
that the crowns deflate when expansion in the steam pipes takes place. Instead
of flanging the plates they may be kept flat, and distance rings inserted.
Also the plates may be elliptical, egg shape or of a special form, so that when
flanged they form a neck to the separator, to catch the condensed water formed by
the steam impinging against the diaphram.

An Improved Combined Steam Separator and Expansion Connection.
I, HORACE EDWARD BALY of 4 Soane Street Ipswich in the County of Suffolk,
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:-
This is a class of Steam Separator more especially adapted for steam pipes,

page_text: between the generators and motive power Engines, and is used for extracting
the superfluous moisture from the steam, so that practically dry steam passes to
the Engine, it has combined with it an expansion connection, so as to prevent
broken pipes and leaky joints.
One way I propose making this separator, is by flanging two circular plates to
a hat shape form, the two flanges coming together form a receiver, between these
two flanges, I insert a flat circular plate or diaphram, and all three plates are
rivetted or bolted together. The crowns of the two hat shaped plates are either
flat or corrugated and on or near the centre of these crowns, are fixed the inlet
and outlet steam pipes, holes being cut in the crowns to suit the required size of
pipes. A hole or perforation is made in the top of the diaphram plate, so that
when the steam enters the separator, it impinges against the diaphram, and then
takes an upward course, and passes through the hole or perforation in the
diaphram and down again to the outlet pipe.
One or both of the crowns may be made of a flexible material and may either be
flat or corrugated, the corrugations running concentric with the centre of the
crowns, in such a way that the crowns deflate when expansion in the steam pipes
takes place.
In order that my invention may be better understood, I will describe the same
by reference to the accompanying drawings.
Figure 1 shows a sectional elevation and Figure 2 an end elevation of a com-
bined steam separator and expansion connection, in which a, and b, are the two
circular flanged hat shape forms, and c, a circular flat plate, or diaphram, rivetted,
or bolted between the flanges of a, and b. A semi-circular hole 7 is cut in the top
of the diaphram'e, this forms the steam separator portion, in this figure the crowns
of the flanged plates are rigid to withstand the pressure of the steam, and the
expansion of the pipe is allowed for, by attaching to one crown an ordinary sliding
pipe f, with its stuffing box g and gland h. J, is a drain pipe leading to a steam
trap, to take the superfluous moisture away.
Figures 3, and 4, are similar to Figures 1, and 2, as regards the separator, but
in place of the sliding pipe, (to allow for expansion of the steam pipe), I make the
crown plates flexible, and they may be either flat, as shown at a, or corrugated as
shown at b, the crowns having sufficient elasticity to allow for the expansion of
the steam pipe.
In order to prevent too much pressure inside the separator from forcing the
flexible crowns outwards, I employ springs as shown in Figures 5, 6 and 7, in such
a manner, as not to prevent the expansion of the pipes from forcing the crowns
inwards.
A laminated spring k is shown in Figure 5. In Figure 6, two cross bars 1, 1,
are fixed to the crowns of the flanged plates a, and b, and connected together by
a cross bolt m, and a spring n, on either or both ends of the bolt m.
In Figure 7, I make the Diaphram c, dished, in order to give support to the
flexible crown b, the strain being taken off by the bolts m, m, and springs n, n.
The springs may be arranged outside as well as inside the separator.
When the separator is used on a vertical pipe, it may be of the form, as shown
by Figure 8, c, being the diaphram with holes around its periphery, f, the inlet
pipe, g, a recess for the accumulation of water, and j, the drain pipe, the crown a,
being flexible and the crown b, being rigid.
This separator may also be used for hot water, or hot air pipes.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A steam separator made as described and shown on drawings herewith

page_text: 3. A steam separator made in combination with an expansion connection as
shown and described.
4. The use of springs for the purpose specified.
