I WILLIAM WORBY BEAUMONT 229 Norwood Road Herne Hill London Engineer
do hereby declare the nature of this invention to be as follows:-
Although the exhaust steam from engines fitted with surface condensers is passed
back to the boilers as water, there is a small waste of water in its cycle from boiler to
engine & engine to boiler which must be made up by water occasionally added to the
boiler from without. My invention consists in arrangements and apparatus by means
of which I make this addition of water in the condenser or within the engine exhaust
pipe near the condenser where it does some of the work of condensing and is itsolf
heated & passes to the boiler as heated feed water. In applying my invention to the
boilers or engines of seagoing ships I also introduce the water by suitable arrange-
ments within the exhaust pipe or within the condenser. I make special arrangements
for the production of vapour from water so introduced the vapour being afterwards
condensed in the condenser and the salt (or other impurities) blown drawn or taken
away from the receptacles provided for it so as to prevent its getting into the
condenser. In one case I insert an evaporating vessel within the exhaust pipe near
the condenser or on the top of it and supply this vessel with water from the circulating
or other water by a pipe or passage provided for it, the vessel being supplied with
rather more than must be evaporated the excess being occasionally passed away
through a pipe or passage made for it. The water may be introduced so that it
trickles in rills or in a film down the inside surface of the exhaust pipe or within a
vessel as above mentioned or it may fall as a shower or enter in the form of jets and
arrangements may be made to cause the evaporating vessel to close by a valve when
it is necessary to stop evaporation for occasional blowing through. A cone or similar
shaped vessel may be inserted within the exhaust pipe & made to act as an annular
evaporating & as salt water vessel.
Evaporating tubes coils or pans may be inserted within the condenser or exhaust
pipe to suit the arrangements of the pipe, the engines, & the condenser, and with
supply & blow off or salt removing devices also made to suit these arrangements.
The supply to the condenser or apparatus described may be controlled by a valve
admitting a small quantity at each pulsation in the condenser.

page_text: I WILLIAM WORBY BEAUMONT of 229 Norwood Road Herne Hill Surrey,
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 :--
Although the exhaust steam from engines fitted with surface condensers is passed
back to the boilers as water there is a small waste of water in its cycle from boiler to
engine and engine to boiler which must be made up by water occasionally added to
the boiler from without.
My invention consists in arrangements and apparatus by means of which I make
this addition of water in the condenser or within the engine exhaust pipe generally
near its junction with the condenser where it does some of the work of condensing
and is itself heated and passes to the boiler as heated feed water.
In applying my invention to the boilers or engines of sea going ships I also
introduce the water by suitable arrangements within the exhaust pipe or within the
condenser. I make special arrangements for the production of vapour from water so
introduced the vapour being afterwards condensed in the condenser and the salt or
water heavily charged with salt, or other impurities, blown drawn or taken away from
receptacles provided for it so as to prevent its getting into the condenser or into the
fresh feed water.
In one case I insert an evaporating vessel within the exhaust pipe near the
condenser and supply this vessel with water from the circulating, or other, water by
a pipe or passage provided for it the vessel being supplied with rather more water
than must be evaporated the excess being occasionally passed away through a pipe or
passage made for it. The water may be introduced so that it trickles in rills or in a
film down the inside surface of the exhaust pipe or within a vessel as above mentioned
or it may fall as a shower or enter in the form of jets and arrangements may be made
to cause the evaporating vessel to close by a valve when it is necessary to stop
evaporation for occasional blowing through.
A cone or similar shaped vessel may be inserted within the exhaust pipe and made
to act as an annular evaporating, and as salt water, vessel. Evaporating tubes, coils,
or pans may be inserted within the condenser or exhaust pipe to suit the arrangement
of the pipe, the engines, & the condenser and with supply & blow off or salt removing
devices also made to suit these arrangements.
The supply to the condenser or apparatus described may be controlled by a valve
admitting a small quantity at each pulsation in the condenser.
My invention will be more clearly understood by reference to the drawings here-

page_text: unto attached which show several modes of carrying it into effect. Similar parts are
marked by the same letters.
In Fig. 1, C represents part of a usual form of condenser A being the exhaust pipe
into which steam enters in the direction of the arrow V from the engine. Within
the exhaust pipe is placed a vessel B to which water is supplied from a convenient
source as from the circulating water passing away from the condenser, a sufficient
quantity being passed through the pipe D which is fitted with a cock. The height of
the water in the evaporating vessel B is shown by a gauge glass J and in some cases
an overflow pipe is fitted in the upper part of B which carries any excess of water
admitted to a vessel attached to the lower part of the condenser, or formed therein,
from which it is run off into the bilge or elsewhere, the action being as will be
described with reference to the salt water pipe E tank or vessel F & cock G.
The vapor from water admitted to the evaporator B passes off by the holes in the
top part thereof and enters the condenser where it is condensed and passes away to
the boiler.
When it is necessary to remove the water which by evaporation in B has become
dense with salt, the cock on the pipe E is opened, G being closed and the water runs
into the tank F. When it has done so the cock E is closed and the water run away
from the cock G a valve opening outward being fitted as at H to allow of any escape
of air and a small cock or valve similarly fitted to allow air to enter when the water
is being run out. The tank or vessel F and its connected pipes & valves must be
placed in positions suitable but always somewhat below the condenser. Although
shown near the condenser the evaporator may be placed in any suitable position
between condenser & Engine.
In Fig. 2, the evaporator is a conical vessel B which leaves an annular space M M
for the reception & evaporation of the salt water which may be supplied direct to the
annular space as it is into the evaporator B of Fig. 1, or it may be supplied in the
manner shown the pipe D leading the water to a ring pipe K which delivers
the water into the space M by allowing it to flow in the form of a thin film all round
the inside of the exhaust pipe A. The pipe K may have the forms shown at Figs. 6
and instead of an open lip as at K Fig. 6 it may have a number of small holes as
in K Fig. 6. The necessary water may enter the pipe D at X or may be elsewhere
obtained, and the salt water may be carried away by a pipe E provided with the
necessary cocks and draw off arrangements described in reference to Fig. 1.
In Fig. 3 a coil L takes the place of the lower part of the evaporating vessels B
of Figs. 1 & 2 the coil leading its heated water to the trough shaped evaporating
annulus B. The water enters by pipe D as in the preceding cases the end of the pipe
being screwed into a piece N to which also the lower part of the coil is attached.
The draw off pipe E is attached in a similar manner and the necessary cocks and
draw off apparatus will be understood to be necessary in this case as in Figs. 1 & 2.
In Fig. 4 is shown a modification in which short trunk pipes P are attached to the
exhaust pipe & to the end covers of these trunks are attached evaporating trays K to
which water is admitted by cocks at D, D, from the small tanks T. T. outside the
covers, the quantity of water which needs to be evaporated being admitted by the
cocks W into the tanks T and the cocks D being so set that they will just allow this
quantity to enter the trays K. The trunks P may be as shown or may be larger or
several in number so as to contain more trays or the trays may be put into the
exhaust pipe or into the condenser so long as they be placed so that the same object
of evaporating water in the exhaust pipe or the condenser be attained.
Fig. 5 shows a modified form of top to the form of evaporating vessel shown in
Fig. 1, and Fig. 7 shows a form of gauge glass which I prefer to use for the apparatus
herein described.
Below the ordinary & well known water gauge J is placed the necessary apparatus
for holding a larger glass tube S the means of holding the tube S being similar to
that generally used for holding a gauge glass. Within this tube I place a šalinometer
which may thus be always visible & readable without any operation for that
purpose.

page_text: Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that I do not confine my
choice of detail to that shown & described and that what I claim is
1. In the exhaust pipe or the condenser of surface condensing engines the
admission of the necessary quantity of feed water to make up for waste by means
of apparatus arranged therein and connected therewith substantially as shown and
described.
2. In the exhaust pipe or the condenser of sea-going surface condensing engines,
the admission of the necessary quantity of feed water to make up for waste by means
of apparatus arranged therein and connected therewith substantially as described and
shown.
