Improvements in Bilge Ejectors.
I, CHARLES SPENCER MADAN, of 34 Crowther Street, Salford, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved method of securing the non-return delivery
valves of steam jet bilge ejectors, such as are used on hoard of torpedo boat
destroyers, and other war vessels.
The delivery end of my ejectors consists of a globular chamber, forming a part of
the body casting, having at one side the outlet for the bilge water to be ejected,
and provided with a hinged non-return valve, opening towards the above mentioned
outlet.
In order to secure that this non-return valve shall remain closed when the ejector
is not in use, I provide in a convenient position, a stuffing box, in which slides &
spindle, so arranged that, when it is pushed inward, the end engages a projection on
the hinge of the non-return valve, and prevents it opening. When the spindle is
pulled outward, the valve is released, and is free to open.
In another form of my invention, the spindle is screwed, and is forced inward or
withdrawn by turning it, so securing or releasing the non-return valve, as previously
set forth.
The spindle may also be operated by means of a cam, crank, lever, or other
contrivance for advancing and withdrawing the spindle.
A locking arrangement, consisting of a set-screw, or other suitable contrivance
may be provided, to secure the spindle in any desired position.

Improvements in Bilge Ejectors.
I, CHARLES SPENCER MADAN, of 34, Crowther Street, Salford, in the County
of Lancashire, 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 bilge ejectors, and has for its object to provide an
improved method of and means for securing more rapidly than heretofore the
non-return delivery valves of steam jet bilge ejectors such as are used on board of
torpedo boat destroyers and other war vessels.
I will fully describe my invention in reference to the accompanying drawings in
which the figures are sectional views illustrating various ways by which I carry
into practical effect.

page_text: The delivery end of my ejector consists of a globular chamber C forming a part
of the body casting having at one side the outlet O for the bilge-water to be
ejected, and provided with a hinged non-return valve V opening towards the above
mentioned outlet O. In order to secure that this non-return valve V shall remain
closed when the ejector is not in use, according to one arrangement I provide in a
convenient position such as illustrated a stuffing box B in which works a push and
pull spindle S so arranged that when it is pushed inwardly to the position shown in
full lines in Fig. 1 its inner end s engages a projection formed above the hinge
of the non-return valve V and prevents it opening. When the spindle is pulled
outwardly its ends clears the projection and the valve is released and is free to
open as shown by the dotted lines.
In another arrangement of my invention the spindle S is screwed either with a
moderately pitched thread as in Fig. 2, or with a quickly pitched thread as in
Fig. 3. When forced inwards by turning the handle H its inner end may act
directly on the back of the valve V as in Fig. 2, or upon a projection thereupon as
shown in Fig. 3 and described in reference to Fig. 1. In Fig. 2 I have illustrated
and use in combination with the lower pitched thread a finer thread cut on the
upper part of the spindle, and a fly lock out N for securing the spindle in the closed
position of the valve V.
In Fig. 4 I have shown the spindle operating upon the valve as in Figs. 1 and 3,
but it is itself actuated by a lever L with a slotted connection thereto and
fulcrummed at l.
In Fig. 5 a cam C is formed on the inner end of a part rotary spindle adapted to
close the valve when in the position illustrated and release same when turned into
the position shown by the dotted lines.
A set screw P is provided to limit the distance of travel of the spindle in
Figs. 1 and 4.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The herein described improved method of and means for securing and releasing
the non-return delivery valves of steam jet bilge ejectors.
2. In a bilge ejector, the use and arrangement in combination with the non-return
delivery valve of an adjacently disposed spindle adapted to act upon the said valve
substantially as and for the purposes set forth.
3. The several arrangements of the operating spindles and non-return valves of
bilge ejectors shown in the figures.
