COMPLETE SPECIFICATION.
Improvements in Steam Generators.
I, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street, Strand W.C. London, Civil Engineer do hereby declare
the nature of this invention a communication to me from abroad by George
Washington Sloane of Brooklyn, State of New York, United States of America
Manufacturer, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to certain improvements in steam generators as pointed out
in the following Specification and claims and illustrated in the accompanying
drawing in which
Fig. 1 is a transverse vertical section in the plane xx
Fig. 2 is a similar section in the plane y y Fig. 3.
Fig. 3 is a longitudinal vertical section.
Fig. 4 is a horizontal section in the plane z z Fig. 3.
Fig. 3.
In this drawing the letter A designates a steam boiler, B B are the furnace walls
and C is the fireplace. At a slight distance from the rear end of the boiler is
situated a drum D which rises in a vertical direction from the mud drum E and
this mud drum connects with the boiler A by a pipe a and it is provided with a
blow off cock b. Its rear end extends through the furnace wall and its position is
at such a level, that it is not in the course of the flame and that it remains
comparatively cool. From the drum D extend pipes c c in opposite directions and
the outer ends connect with heads d d' respectively (best seen in Fig. 1). Each of
these heads is provided with a hand hole e el respectively and in the rear end
of the furnace are two doors F F¹ (Fig. 4) through which convenient access can
be had to the hand holes e e¹. From the heads d d' extend pipes ff' which connect
with drums G G' situated near the front wall of the furnace and these drums are
provided with hand holes g g' respectively one opposite to the front end of each of
the pipes ff. In the front wall of the furnace are two doors H H¹ opposite to
the hand holes y g¹ so that when the doors F F¹ and H H' are opened, convenient
access can be had for cleansing the pipes ff. I is the fire door which gives
access to the fireplace C. The drums G G₁ connect by pipes ¹ respectively
with the steam space of the boiler A. The feed water is introduced by a pipe J
directly into the boiler, and it descends through the pipe a into the mud drum E in
which the largest portion of the impurities contained therein is deposited and can
be blown off through the cock band from the mud drum the comparatively pure
water passes up through the drum D into the pipes e c' and thence through the
heads d d and pipes into the drums G G and through the pipes / back
into the boiler A. During its passage through the pipes c c and ff, the water
becomes highly heated so that it enters the boiler A in the form of a mixture of
water and steam and whenever it is found that a sediment has been formed in the
pipes ff such sediment can be readily removed by opening the doors F F¹
and H H and the hand holes e e' and g through which easy access can be
obtained to the interior of the pipes ƒƒ¹.
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. The combination with a boiler and a feed pipe leading directly thereinto of
a mud drum E having a pipe a extending into the boiler, a drum D rising from
the mud drum and pipe connections between the drum and steam space of the boiler
substantially as described.

page_text: 2. A steam generator consisting of a furnace structure, a boiler A, a mud
drum E situated beneath the boiler and connected to the same by a pipe a, a
drum D connected to the mud drum and extending up between the boiler and the
rear wall of the furnace structure, pipes c c¹ extending from the drum D in opposite
directions, heads d d' connected to the ends of the pipes c c and provided with
hand holes e e¹ doors F F opposite to said hand holes, drums G G₁ between the
front end of the boiler and the front wall of the furnace structure, pipes ƒ fl
extending from the heads d into the drums G G hand holes g g in the
drums G G doors H H¹ opposite said hand holes and pipes leading from the
drums G G¹ into the boiler substantially as described.
