PROVISIONAL SPECIFICATION.
Improvements in Steam Generators.
I, ARTHUR GEORGE BROWN, of Globe Iron Works, Bolton, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
The invention relates to steam generators in which water is heated in inclined
tubes and the object is to so construct and combine the parts of such generators as
to facilitate construction and obtain increased efficiency.
A generator under my invention has the following parts combined as herein set
forth. Inclined tubes are connected at the ends in vertical series. The lowermost
end of the bottom tube of each series is connected to a transverse mud collector.
Both ends of the top tube of each series are connected to transverse carrying boxes.
Resting on the said carrying boxes are two or more steam and water vessels.
Transversely above the said vessels and connected thereto is a steam chest. The
whole of the parts up to the level of the water is enclosed in a furnace having
dividing and directing partitions for the products of combustion and heated gases.
The carrying boxes for each steam and water vessel are preferably made in three
pieces.
The inclined tubes and other parts of the above and like generators are made
with nipples connected by ferrules or pipes expanded into the nipples.
Under a modification the inclined tubes of the above and like generators are
expanded at the ends into circulating heads and the heads, mud collector, and
carrying boxes are connected together by bolts and socket joints.

Improvements in Steam Generators.
I, ARTHUR GEORGE BROWN, of Globe Iron Works, Bolton, in the County
of Lancaster, 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 invention relates to steam generators in which water is heated in inclined
tubes and the object is to so construct and combine the parts of such generators as
to facilitate construction and obtain increased efficiency.
A generator under my invention has the following parts combined as hereinafter
set forth. Inclined tubes are connected at the ends in vertical series. The lowermost
end of the bottom tube of each series is connected to a transverse mud collector.
Both ends of the top tube of each series are connected to transverse carrying boxes.
Resting on the said carrying boxes are two or more steam and water vessels. Trans-
versely above the said vessels and connected thereto is a steam chest. The whole
of the parts up to the level of the water is enclosed in a furnace having dividing
and directing partitions for the products of combustion and heated gases.
The carrying boxes for each steam and water vessel are preferably made in three

The inclined tubes and other parts of the above and like generators are made

DESCRIPTION OF THE DRAWINGS.
Fig. 1. is a side elevation and Fig. 2 an end view parts being in section of a
generator constructed in accordance with my invention. a are inclined tubes
connected at the ends in vertical series by means of nipples 6 secured to or formed
with the tubes and within which are expanded ferrules d to make a watertight
joint. The lowermost end e of the bottom tube of each series is connected as above
set forth to a transverse mud collector f. Both ends of the top tube of each series
are connected by nipples c and pipes d, to pieces g, placed so as to form transverse
carrying boxes. Resting on and connected to the said carrying boxes with free
communication, are two steam and water vessels h. i, is a steam chest placed
transversely above and connected to the steam and water vessels . j, is the furnace
enclosing the above parts up to the water level. k, are dividing and directing
partitions for the products of combustion and heated gases. The usual steam and
water connections and fittings are provided.
Fig. 3, is a side elevation and Fig. 4 an end view, parts being in section, of a
modified steam generator under my invention. Here the transverse carrying boxes g
are in one piece and the inclined tubes a', are fitted into circulating heads 1. The
heads, mud collector f, and boxes g, are connected by socket joints m, fitting
against metallic rings n, and held in position by bolts and nuts.
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
claim is :-
First. Water tube steam generators constructed substantially as herein set forth.
Second. Water tube steam generators having parts connected by nipples and
ferrules or pipes substantially as set forth.
Third. Water tube steam generators having parts connected by socket joints, and
bolts and nuts substantially as set forth.
