or other Gas or Vapour.
I, WILLIAM NATILAN DACK, Consulting Engineer, No. 6, Old Lane, Moorside,
Swinton, near Manchester, Lancashire, do hereby declare the nature of this inven-
tion to be as follows:-
My invention consists of a pipe to convey steam or other fluids. This pipe is
preferably made larger than the range of pipes of which it will form part. In
this pipe is fixed a number of conical pipes or tubes, fixed together by any suitable
means, the lesser diameter of such tubes always facing the current of the passing
fluids.
The first conical tube is preferably of less diameter at the lesser end than that
of the second tube and so to No. 3 or any other number. The first tube being
fixed over the small end of the 2nd and so on to any number, each tube being
fixed over the small end of the next leaving an annular space between 1st 2ndl
and so to any number of tubes.
These conical tubes are inserted into each other to any necessary distance and
allow of passage of fluids through their lesser or greater diameters.
The aeriform fluids being the most free from water at the centre of the pipe
than at or near the periphery any water flowing with the fluids will impinge against
the outside of the conical tubes and be thrown out (by its centrifugal force) against
the periphery of the conveying pipe and will thus fall and be taken away through
a pipe or branch on the pipe enclosing the conical pipes. The apparatus may or
may not be connected to an ordinary trap.
The last conical tube or the one nearest to the outflow may be flanged and by this
flange secured again to the range of pipes to which the apparatus is to be applied.
The object is to construct such apparatus so that the water is caught by being
thrown outwards by rushing against the outside of a number of conical tubes the
least diameter of which faces the current of the steam or other gas.

I, WILLIAM NATHAN DACK, Consulting Engineer, No. 6, Old Lane, Moorside,
Swinton, near Manchester, in the County of Lancaster, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and certained in and by the following statement:-
--
My invention relates to improvements in apparatus for separating water or other
liquid from steam, compressed air, or other gas or vapour.

page_text: In carrying out my invention I propose to employ a pipe in which are placed a
number of conical or conically formed pipes or tubes fixed together by any suitable
means, the lesser diameter of such conical tubes facing the current of the passing
fluids.
The conical tubes are inserted into each other to any necessary distance, and allow
of passage of fluids through their lesser as well as their greater diameters, an
annular space being left between the conical tubes to allow of the fluids passing
through their larger diameters.
In some cases the water may be thrown by centrifugal force by the conical tubes
being arranged to revolve, or by means of suitably disposed vanes or screw threads.
In all cases the water will be drained away through a pipe suitably fixed.
In performing my invention I proceed in the following manner, making reference
to the accompanying five sheets of drawings. Similar letters denote the sam
parts whenever occurring.
Fig. 1 is a sectional elevation of my improved separator, suitable for fixing in
a range of steam or other gas, or vapour conveying pipes.
Fig. 2 is in part a sectional elevation shewing my invention as applied inside
a steam boiler or other generator.
Fig. 3 is a section showing the apparatus as applied in connection with a
receiver placed between the cylinders of compound engines.
Fig. 4 is a section shewing a simplified arrangement of conical tubes, also
shewing drain pipe fixed at the end of chamber.
Fig. 5 is a section shewing the apparatus with conical tubes fixed together by
means of screws, or rivets, with end cone blank at the smaller end, and will be
applicable to certain purposes.
In the constructions illustrated by Fig. 1 to 5, a designates the conveying pipe,
6 the conical tubes attached to conveying pipe a by any suitable means, the smaller
end of these conical tubes facing the current of fluids, as shewn by arrows, and c
the outflow for separated water. The pipe c¹ may be connected to a steam trap
or as otherwise arranged.
In Figs. 1, 23, & 4, the apparatus is arranged to work horizontally, but in
case of its being required to work upright or inclined, the discharge pipe c¹ may
be fixed at d Figs. 1, & 5 the plug being placed at c and the pipe at d.
The pocket c may be extended in length and may have fixed thereto a glass
water gauge to show the level of water in pocket c.
In Fig. 2 the apparatus is shewn as fixed inside a boiler, either double ended,
as shewn, or single. a is the conveying pipe, 6 the conical tubes shewn in elevation,
the drop pipa may be carried below the water line of the boiler, and thus all
water separated will flow bark below the water line. f is the branch or block to
which the stop valve is attached as in a Lancashire boiler. The piping d
may in some cases stop short of water line of boiler, as shewn in dotted lines at s.
In Fig. 3 is shown the apparatus as applied in connection with a receiver as is
usually fixed, between the cylinders of compound engines. is the conveying
pipe from high to low pressure cylinder, the receiver, c the separated water pipe.
In this case the drop pipe is conveyed through the receiver r, and enters into
another and larger pipe which conveys the collected water from both the pipes a,
and the receiver to a trap or otherwise.
In Fig. 5 is shewn an arrangement of the apparatus suitable for placing in an
upright or inclined position, always flowing downwards.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:-
1st. A number of conical or conically shaped pipes, or tubes (either fixed or
revolving) placed in a pipe for conveying steam or other vapour from one place
to another, in the manner, and for the purposes herein set forth.

page_text: 2nd. The combination of the pipe a, the conical tubes 6, and the pocket c for
the purpose herein set forth.
3rd. With reference to the Figure 3, the combination of the pipe a, conical
tubes b, pocket c, pipes c¹, c³, and receiver r.
4th. With reference to Figure 2 the combination of pipe a, conical tubes b,
pocket c, and the open pipe c¹.
5th. The arrangement and construction of parts as set forth, with reference to,
and shewn in the different figures or sets of figures of the drawings for the purposes
specified.
