PROVISIONAL SPECIFICATION.
Improvements in Steam and Water Separators or Steam Dryers.
I, JOSEPH HALL, of 63 Royal Exchange, Manchester in the County of Lancaster,
Engineer do hereby declare the nature of this invention to be as follows:-
-
The object of my invention is to make an automatic steam & water separator, &
consists of an improved combination & arrangement for dividing & draining the
condensed water from the steam in its passage through a long range of pipes, say to a
steam engine, steam pump, dryer &c., by passing the whole of the steam through the
separator. This consists of an outward casing, with inlet & outlet ports, having two
upstanding tubes (internally) in the said casing, forming two annular steam chambers,
the receiving tube (A) having a cone dish & drain pipe at the top, & at about its
centre & base numerous holes for the admission of steam jets to the inner annular
steam chamber.
The discharge tube (B) in connection with the outlet port projects into the receiving
tube (A), the drain water being returned to the boiler through the discharge port (C),
or else to the atmosphere by a vertical column of small area, through a regulator valve
& combining tube, which prevents the exit of steam & causes the action to be so
regulated as to be quite automatic.

COMPLETE SPECIFICATION.
Improvements in Steam and Water Separators or Steam Dryers.
I, JOSEPH HALL of 63 Royal Exchange, Manchester in the County of Lancaster,
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 consists of an improved combination & arrangement for dividing &
draining the water of condensation from the steam after its passage through a long
range of piping say to a steam engine, steam pump &c., the whole of the steam being
passed through the separator or dryer, & there relieved of the water, which may be
returned to the boiler or otherwise disposed of.
The dryer consists of an outward casing S S with inlet I for steam.
In the centre
of the casing S S are two outstanding tubes A A & B, which divide the internal space
within the casing S S into three separate chambers, viz.--the annular spaces EE &
TT & the chamber B in connection with the outlet G. Upon the end of the tube A A
nearest to the inlet I is an inverted conical receiver or dish D provided with a tube F
at its apex for the purpose of draining off the water. About the centre of the
tube AA & round its circumference are perforated a number of holes O for the
entrance of steam into chamber T T, & at the end of tube A. A, nearest the outlet G,
other holes for the entrance of water. Passage () (or C₁) is provided at bottom of the
apparatus to convey the water into drain pipe.
The separator is applicable to a vertical range of steam pipes, or to a horizontal
range. The vertical position is shown full in the drawing, & for the horizontal
position the plug S, is removed from passage C₁ to C, & the drain pipe attached at C₁₂
as shown by the dotted lines.
The drain pipe is provided with a vertical ejector column L, & a regulating
valve.
The action of the apparatus is simply as follows:-
Steam entering at inlet I is deflected directly against receiving pan D, the water

page_text: collecting in pan D & passing through passage F, & holes round A A, into drain
passage. Or if the separator is placed horizontally the water passes through F &
lower holes round A A into drain passage C₁, filling the lower portion of annular
space E E. Meanwhile the steam after striking pan D, rises, fills upper portion of
annular space EE, & passes through holes "0" into second annular space TT. Here
the steam again rises, & in so doing parts with any water still remaining in it—which
falls to lower part of chamber, the steam meanwhile passing into chamber B, and
through the outlet G.
By means of the vertical column ejector L & regulating valve, a column of water of
a constant height is always maintained in the drain pipe, so that the steam is "trapped,"
& its escape prevented. The valve is opened to its required working position, & left,
the action being automatic. A glass gauge may be used in connection with this
column to assist or simplify the regulating of the column of water.
Having now particularly described & ascertained the nature of my said Inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is:
I. In a steam dryer or separator the two outstanding tubes A A & B forming the
three chambers, substantially in the manner & for the purpose herein set forth.
II. In connection with a steam dryer the use of the vertical ejector column L, &
valve for regulating, substantially as described & shown herein.
