COMPLETE SPECIFICATION.
Improved Apparatus for Separating Water from Steam, Compressed
Air, or other Gas or Vapour.
We, ORLANDO OLDILAM, Engineer, of the Firm of Oldham & Son, Steel Coil
Piston Works, Denton, and WILLIAM NATHAN DACK, Consulting Engineer, of
6, Old Lane, Moor Side, Swinton, both near Manchester, in the County of Lan-
caster, 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 invention relates to further improvements upon the separating apparatus
for which Letters l'atent No. 6,389 were granted to the said William Nathan
Dack, bearing date March 16th, A.D. 1898, the objects of the present invention
being to simplify and improve the construction and operation of such apparatus.
The nature of our said improvements and the manner in which the same is
to be performed or carried into practical effect will be readily understood on
reference to the two sheets of drawings hereunto annexed and the following
explanation thereof.
The drawings represent four modifications or arrangements of the invention.
In the arrangement shown in longitudinal section at Fig. 1 the outer pipe or
casing a forms a portion or continuation of the range of conveying pipes for the
steam, compressed air, gas, or vapor from which the water or moisture is to be
separated, and is provided with a pocket a¹ at the lower end for carrying off
the water. In this casing a we fix a cylindrical tube 6 of about the same diameter
as the conveying pipes and having fixed on its free end a thin cone e the smaller
end of which is in a direction meeting the flow of steam, air, gas, or vapour
(as shown by the arrows).
The dry portion of the steam &c. being in the centre of the column passing
along the conveying pipes will pass without obstruction straight along the
pipe b, whilst the denser moist portion thereof and the water being close to the
outer periphery of the pipe will, on meeting the edge of the smaller end of the
cone c, be separated therefrom and pass up the annular passage d formed between
the outside of the cone c and the inner surface of the conical part of the casing a
and will with the water of condensation fall into the pocket a¹ at the lower end
thereof when it can pass off in any convenient manner.
In the arrangement shown at Fig. 2 the form of the outer casing a is somewhat
aried, the mouth of the inner tube being brought to a sharper edge and the
hin cone c dispensed with, so that the inner diameter of the tube b is not con-
racted at the mouth but may be of the same diameter as the inside of the con-
eying pipes. The object of the shoulder 61 near to the mouth being to prevent
ny tendency caused by the suction of the passing column of steam to draw back
ny particles of moisture which may adhere to the outside of the tube b.
Fig. 3 shows a further simplification of the invention wherein the outer
asing a is made shorter and more in the form shown at Fig. 1 the inner tube b
ot being contracted but of the full diameter throughout, and the outlet a¹ cast
er formed in one piece with the flanged end of the inner pipe b.

page_text: These three arrangements may also be used in a vertical position when the
passage of the steam &c. is in a downward direction, but for an upward current
we make the apparatus in the form shown at Fig. 4 the shape of the outer
casing a being modified and the well or pocket a¹ formed at the bottom thereof.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved apparatus for separating water from steam compressed air or
other gas or vapours substantially as herein before described and illustrated by
the annexed drawings.
