Moving them.
1 EDGAR SMART of 16 Basinghall Street in the City of London Civil
Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to such apparatus for propelling and otherwise moving
ships and other vessels as consists of steam ejectors arranged in pipes through
which water is caused to pass by the action of the ejectors in order to produce the
required motion of the vessels in which the said apparatus is fitted and my said
invention consists of the improvements hereinafter described in the arrangement
of the ejectors the object of the said improvements being to provide for ready
variation of the direction of action of the said ejectors.
According to my said improvements I so mount the ejectors in the water
conducting pipes or in chambers communicating therewith that the said ejectors
are capable of being placed either in such positions that steam issuing from them
will cause the passage of water through the said pipes in one direction or in such
positions that the steam will cause the passage of water through the said pipes in.
a different direction. Or I so form the ejectors that they may be caused to act in
two or more directions and I provide for their action in one or other direction
according to requirements by so arranging the steam passages or portions thereof
that their position relatively to the ejectors is capable of variation for the purpose
of determining the direction of action of the ejectors.
My said improvements are applicable both in cases where ejectors are arranged
singly in water couducting pipes for the purpose herein before stated and in cases
where a series of two or more ejectors is arranged in one water conducting pipe for
the said purpose.

Improvements in Apparatus for Projecting Water from Ships
and other Vessels for the Purpose of Propelling and otherwise
Moving them.
I EDGAR SMART of 16 Basinghall Street in the City of London Civil
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 such apparatus for propelling and otherwise moving
ships and other vessels as consists of steam ejectors arranged in pipes through
which water is caused to pass by the action of the ejectors in order to produce the
required motion of the vessels in which the said apparatus is fitted and my said

page_text: invention consists of the improvements hereinafter described in the arrangement of
the ejectors for the purpose of providing for ready variation of the direction of
their action.
My said improvements consist first of the arrangement hereinafter described
whereby variation of the direction of motion of the vessel is produced by variation
of the position of the ejector relatively to the water conducting pipes and secondly
of the arrangement hereinafter described whereby variation of the direction of
motion of the vessel is produced by variation of the position of the passage
through which steam enters the ejector.
I will describe my said improvements with reference to the accompanying
drawings in which the water pipes or passages are marked a the ejectors and the
steam pipes c.
The first of the said arrangements is illustrated in Figures 1 and 2 of the said
drawings which figures represent sections taken in planes at right angles to each
other. In this arrangement the ejector is formed or secured in a drum d having
trunnions efformed on it which work in bearings in the sides of a circular
chamber connected to and communicating with the water pipes a a forming the
water passage and steam is conveyed to the ejector from the pipe c through a
passage in the trunnion e. To the other trunnion fa crank k is secured to admit
of the drum d being turned for the purpose of placing the ejector 6 in the position
indicated in broken lines in Figure 2 when reversal of the direction of motion of
water through the pipes a, a is required. It will be understood that the water
pipes a, a may be connected to the chamber j at points other than or relatively
different from those illustrated and that additional water conducting pipes may
be connected to the said chamber in order to admit of water being ejected from
various parts of the ship by turning the drum d so that the ejector will be in
line with any desired one of the said additional pipes.
The second of the arrangements hereinbefore referred to is illustrated in
Figures 34 and 5 of the accompanying drawings Figures 3 and 4 being longitudinal
sections taken in planes at right angles to each other and Figure 5 being a transverse
section taken on the broken line in Figure 4. In this arrangement the ejector b
is provided with two discharge nozzles so as to be capable of acting in two directions
and is formed or secured within a chamber communicating with the water
pipes a a and is furnished with a steam inlet consisting of a hollow plug m which
is in communication with the steam supply pipe c and has an orifice n on one side
through which steam passes to the ejector. By means of a crank o the said plug m
may be turned so as to bring the said orifice n opposite either of the nozzles of the
ejector according to the required direction of action of the said ejector. As will
be seen by reference to the transverse section Figure 5 the ejector and the water
passage are so formed and the ejector is mounted in such a position within the
water passage that there is a free water way entirely around or on all sides of the
ejector nozzles.
Where provision is required for causing water to be discharged from the ship at
parts other than those at which the said pipes a a open additional water conducting
pipes are connected to the chamber and the ejector is furnished with additional
nozzles which are respectively in line with the said additional pipes as in
Figure 6 where two additional pipes a' a' and two additional nozzles 6' 6' are
illustrated.
The arrangements illustrated in Figures 1, 2, 3 and 4 of the accompanying
drawings are applicable both in cases where ejectors are arranged singly in water
conducting pipes for the purpose herein before stated and in cases where a series of
two or more ejectors is arranged to act successively on one and the same stream of
water in one water conducting pipe for the said purpose.
The water conducting pipes may be arranged in any desired positions in the ship
or vessel to which the apparatus is required to be applied.
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

page_text: claim as my invention of "Improvements in apparatus for projecting water from
ships and other vessels for the purpose of propelling and otherwise moving
them"
-:
First. Apparatus constructed substantially as herein before described and
illustrated in Figures 1 and 2 of the accompanying drawings that is to say apparatus
consisting essentially of a chamber communicating at different points with the
passage or passages through which the water is to be projected and a steam ejector
mounted within the said chamber on trunnions projecting through the sides thereof
in one of which trunnions is a tubular passage communicating between the interior
of the said ejector and a pipe for conveying steam thereto and the other of which
trunnions is furnished with means whereby the ejector may be turned within the
said chamber for the purpose of placing the nozzle of the ejector opposite either
or any one of the points of communication between the said chamber and the said
water passage or passages.
Secondly. Apparatus constructed substantially as herein before described and
illustrated in Figures 3, 4, 5 and 6 of the accompanying drawings that is to say
apparatus consisting essentially of an ejector so formed and provided with a steam
inlet so arranged that the direction of action of the ejector may be determined by
adjustment of position of the said inlet the said ejector being also so formed and so
mounted or arranged in a water passage or water passages as to leave a free water
way around or on all sides of the discharge nozzles of the said ejector.
