Improvements in Steam Boilers or Generators.
I, ANTOINE ROMAIN THIRION, of 160, Rue de Vaugirard, Paris, in the Republic
of France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to steam-boilers or generators and has for its object the
evaporation of water in a current produced by the circulation of the water in
tubes having two branches placed in a furnace and fixed upon a box with two com-
partments, one of which serves for feeding the tubes and the other for receiving the
evaporated water.
Figure 1 in the accompanying drawing represents by way of example the box
which has two compartments A A' A", B B B wherein the entire series of tubes
terminate.
The box with the tubes fixed thereto forms a generating element. The complete
boiler or generator may be composed of any suitable number of elements. The
tubes can be varied in thickness and length according to the purposes for which the
boiler or generator is to be used or the heating surface to be obtained.
Each element is connected below with a collector C, Figures 2, 3, 4 and 5, which
serves for feeding the compartment A A' A" of the box.

The water is introduced into the tubes through the extremities TT, T, T, T, T.
T T, T, and leaves them in the evaporated state through the extremities T
T
T', which terminate in the second compartment of the aforesaid box.
The evaporated water subsequently passes into one, or more tubes which are at the
upper part of the box and are used for drying the steam. It then passes to the
upper collector D, Figures 2, 3, 4 and 5.
Finally when it arrives at the extremity E of the collector Figure 4, a division
is effected, the water which is carried away in the current, passes down through the
conduit F in order to return to the evaporating tubes, whilst the steam passes
through the conduit G which extends to the steam reservoir H.
The feed water is caused to pass into the steam reservoir by means of a feed
pump or other suitable apparatus, and enters the same either through the tube M
or through the tube N. It is decanted so as to leave its incrustating substances
behind, which latter are collected by any of the known methods. It then descends
through the conduit J to the collector C.
My invention is essentially characterized by the employment and arrangement of
tubes having two branches terminating in the two compartiments of the box upon
which they are fixed, one of the said compartments serving to feed the tubes
and the other to receive the evaporated water before its passage into the drying
tubes.
As indicated in the several figures of the drawing this employment of tubes
having two branches enables
(1) A multitubular boiler or generator with freely expanding tubes to be
obtained;
°
(2) The boiler or generator to be inspected from the front without any necessity
for obtaining access to it from the rear.
(3) The dismountable elements to be closed from the front of the boiler or
generator.
(4) The boiler or generator to be completely emptied by opening the cock cat
the lower part;
(5) Reserve elements to be used in lieu of those which may have been
damaged.

page_text: Independently of the advantages hereinbefore enumerated the described arrange-
ment of the tubes terminating in the two compartments of the above mentioned box
ensures a very active circulation and causes all the parts to come in contact with the
fire, which conditions. are essential for obtaining a great rapidity in getting up
pressure and a great production of steam.
In Figures 6, 7, 8, 9 and 10 are shown various-tubes which can be used according
to the size or use of the boiler or generator.
Figure 6 represents an ordinary bent tube.
Figure 7 represents a tube having a narrow or contracted bend for increasing
the velocity of the circulation in the bend and for giving additional strength to the
metal.
Figure 8.represents a taper tube.
Figures 9 and 10 illustrate a tube having a removable bend.
Any other suitable arrangement may be employed.
The tubes are fixed to the aforesaid box by dudgeoning them like all boiler
tubes, but they may be secured by other suitable means employed for this
purpose.
I can support the extremity of the tubes by a simple cross bar placed in the
furnace at their extremity, as shown in Figure 10, when they are of great length.
The front part of the said box is provided with openings opposite each tube for
These
the purpose of enabling it to be dudgeoned and for inspecting the tubes.
openings are closed by removable plugs or covers a.

COMPLETE SPECIFICATION.
Improvements in Steam Boilers or Generators.
ANTOINE ROMAIN THIRION, of 160, Rue de Vaugirard, Paris, in the Republic
of France, Manufacturer, 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 steam-boilers or generators and has for its object the
evaporation of water in a current produced by the circulation of the water in
tubes having two branches placed in a furnace and fixed upon a box with two
compartments, one of which serves for feeding the tubes and the other for
receiving the evaporated water. In the drawings left with my Provisional
Specification Figures 1 to 10 and in the accompanying drawings, Figures 11
to 14, have shown how my said invention may be conveniently. and advan-
tageously carried into practice.
Figure represents by way of example the box which has two compart-
ments A A¹ A, B B B wherein the entire series-of tubes terminate.
The box with the tubes fixed thereto forms a generating element. The complete
boiler or generator may be composed of any suitable number of elements. The
tubes can be varied in thickness and length according to the purposes for which the
boiler or generator is to be used or the heating surface to be obtained.
Each element is connected below with a collector C,-Figures 2, 3, 4 and 5, which
serves for feeding the compartment A A' A" of the box.

The water is introduced into the tubes through the extremities T T, T₂ T₂T, T,
T, T, T, and leaves them in the evaporated state through the extremities T
T₁.
To which terminate in the second compartment of the aforesaid-box.
The evaporated water subsequently passes into one or more tubes which are at the
"upper part of the box and are used for drying the 'steam. It then passes to. the
upper collector D, Figures 2, 3, 4 and 5.

page_text: I have here inbefore described the case where it was needful to contract the tubes
by making them conical, and I find it simpler to diminish the inlet on the side for
the entrance of the water by means of a plug in order that the water shall be
distributed better to each tube.
Finally I place between each two adjacent tubes a small bar which has for its
object to remove the water or the steam which leaves the tube immediately below
or above according to the direction of the current. This arrangement is of very
great importance when the current in the tubes is very active for facilitating the
inlet and outlet of the water and steam.
The feed of the water to the series of tubes can be effected at a certain height as
shown in Figures 11 and 12 or through the lower part of the box G H Figure 12.
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 what
I claim is -
First. A steam boiler or generator composed of tubes having two bent branches,
terminating in a vertical box with two compartments A A A B B₁ B" for
determining the circulation of the water and carrying above in the same box one
or more drying tubes, substantially as and for the purpose specified.
Second. A steam generator which consists in connecting together any number of
elements arranged as above described and connected with each other as hereinbefore
specified.
Third. The separation of the two compartments G H M N of the box which
receives the vaporizing and superheating tubes in order that the water and the steam
shall be forced to pass through the tubes to move from one compartment to the
other, as shown in Figures 11, 12, 13 and 14 of the drawings.
Fourth. The contraction of the inlet of the tubes on the side upon which the
feed water inlet is arranged.
Fifth. The employment of small partitions or bars of any suitable shape or other
suitable means for removing the current of steam or water from the outlet or inlet
of the other tubes.
