I, LOUIS MARIE GABRIEL DELAUNAY BELLEVILLE, of 1, Rue de L'Ermitage,
St. Denis (Seine), in the Republic of France, 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:-
The object of this invention is to provide a combined steam and feed water
collecting and purifying apparatus for use with steam boilers the internal parts
of which apparatus can be connected and disconnected with great facility and it
is therefore specially applicable for use with marine boilers.
I will describe the invention with reference to the accompanying drawings
in which Figure 1 is a longitudinal vertical section on the line A A B B of
Figure 2. Figure 2 is a transverse section on the line C C of Figure 1.
Figure 3 is a front elevation.
Figure 4 is a longitudinal horizontal section on the line D D DEEEE,
FFF, Figures 1 and 3.
Figure 5 is a transverse vertical section on the line G G Figure 1.
Figure 6 is a transverse section on the line H H of Figure 1.
Figure 7 is a plan shewing the steam inlet.
Two
The body a of the apparatus is cylindrical and its ends b (which should be
made of steel) are each provided with a check-valve in the box c which the feed
water enters through a pipe d it passing into the interior of the apparatus through
the pipes e.
Each end has also fitted to it a water return branch pipe nozzle
or jet f through which the feed water flows into the boiler. In each end above
the valve box c, and the nozzle or jet f is provided a hole g for inspection
cleaning and connecting or disconnecting purposes. These holes are closed by
means of tight doors, or closing devices of any suitable description.
similarly closable holes h h are provided in the side of the body a which body
is fitted, at its lower part with jets or branch pipes to the lower ends of which
are coupled the steam producing or vapourizing tubes of the boiler the upper
ends extending into the interior of the apparatus as shewn.
Above the upper
orifices of the pipes i there is arranged a dome or inverted trough extending
over the whole of the pipes i its object being to deflect downwards the mixture
of water and steam which is forced from the boiler into the apparatus through
the pipes. This dome or inverted trough k is made in parts secured at about
the centre of the apparatus to a support m common to both and consisting of a
bent metal plate attached to the body a in any convenient manner. In the
drawing (Figure 2) I have shewn the means of attachment as consisting of two
angle pieces n n rivetted to the body a the support m being preferably in the
form of an inverted cup bolted to the angle pieces by means of the bolts o.
Each part of the dome or inverted trough is provided with an extension which
At their opposite
rests upon the support m and is secured thereto by bolts q.
ends the said parts of the dome or inverted trough are each provided with an angle
piece r which rests upon a support s rivetted to the body part a the bolts t serving
to retain the dome or inverted trough in position. Each half of the dome or

page_text: inverted trough k consists of two parts connected together by a plate rivetted
to one and secured to the other by bolts u. On either side of the interior of the
body part a, and extending from end to end thereof, there are two bent metal
plates V (Figure 6) rivetted to the body a and intended to prevent the water
deflected down by the dome, or inverted trough, k from rising again along the
walls.
In the centre of the top-part of the apparatus and above the support m is tightly
rivetted the steam-supply chamber W constructed preferably of stout steel. ✗ is
the steam-outlet to which is secured by nuts on the screw bolts y the end of the
steam supply pipe. The steam enters the chamber W through two steam inlet
tubes z provided with perforations as shewn in Figure 7. These tubes z are open
at one end, viz. the end at which they communicate with the chamber W and
they are provided with conical end-pieces or couplings whereby they are tightly
secured in the walls of the chamber W. The opposite ends of these tubes z are
closed; they being each provided with a flange such as 1 which are secured by
bolts 2 to angle pieces 3 rivetted to the body part a. The joint between the
open end of each of the tubes z and the walls of the chamber W is kept tight by
screwing home the bolts 2.
The mixture of water and steam which the boiler discharges into the apparatus
through the pipes or jets i meets the dome, or inverted trough, k which deflects.
it downwards. The water collects in the lower part of the apparatus whilst the
steam rises to the upper part and enters the steam-supply chamber W through
the perforations in the tubes z whence it is supplied to the engine. The feed-
water may come direct from a tank, or any other suitable source of water supply.
The pipes 7, which are bent to point in a direction parallel with the axis of the
apparatus are both arranged on the same side of the pipes or jets i, and divide
the feed water into two currents flowing in opposite directions to each other and
which at their meeting-point are so deflected as to pass over to the other side
of the said jets i and return towards the ends 6 mixing, as they do so, with the
water forced down by the dome, or inverted trough, and then passing through
the jets f into the vapourising tubes.
In apparatus constructed or arranged according to my invention the internal
parts can be disconnected, and removed and replaced and connected with great
facility and without disconnecting or shifting the apparatus itself because they
are retained in place by a small number of bolts or fastenings which are situated
in the vicinity of the inspection holes.
If either half of the dome, or inverted trough, k, when detached, cannot be
sufficiently inclined to admit of its removal through the corresponding inspection
hole, the fastenings u can be removed and the half be again divided.
The principal object of constructing the support m in the shape of an inverted
cup is to enable it to intercept the current of feed-water if there should be only
one inlet for feed water, but I prefer to use two such inlets as at de e in the
drawings so that the feed water can pass unimpeded into the apparatus even should
the temperature of this water happen to be at the time higher than that of the
steam.
All accessory parts and details may be varied according to requirements with-
out departing from the nature of my invention.
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. A combined steam purifier and feed water heater consisting of or comprising
a cylindrical body with an inlet or inlets for feed-water, a dome or inverted trough
arranged above pipes or jets in communication with the vapourizing tubes of the
boiler and a perforated tube and chamber for the escape of steam all substantially
as hereinabove described and illustrated in the accompanying drawings.
2. In an apparatus of the kind claimed by the preceding claiming clause a

page_text: dome or inverted trough made in halves fastened at the centre of the apparatus
to a support common to the said halves, the sides of apparatus being provided
with holes for access to the said support and fastenings and each of the said
valves being connected and fastened at its other end to a support s the ends of
the apparatus being provided with holes for access to these supports and fasten-
ings and each of the said halves being made in parts secured together so that
the said dome or inverted trough can be rapidly taken to pieces substantially as
hereinabove described and illustrated in the accompanying drawings.
3. In an apparatus such as is claimed by the preceding first claiming clause
a steam supply tube made in two parts one end of each part being conical and
open and capable of being forced into openings in a steam chamber while each
of the other ends is closed and provided with a flange which can be tightened
by bolts connected to a bracket and enabling such steam supply tubes to be
readily removed substantially as hereinabove described and illustrated in the
accompanying drawings.
4. The general arrangement and combination of parts constituting the apparatus
substantially as hereinbefore described and illustrated in the accompanying
drawings.
