I, GEORGE EDMUND TURNER, Manufacturer of Steam Generators, of Marion, in
the County of Marion, and State of Ohio, United States of America, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in water-tube steam generators, and the
object is to provide a simple, effective and durable, as well as economical and
convenient, generator of this class. To these ends the novelty consists in the
construction, combination and arrangement of the several parts of the same, as
will be hereinafter more fully described and particularly pointed out in the
claims.
In the accompanying drawing, the same reference characters indicate the same
parts of the invention.
Figure 1 is a front view of my improved water-tube steam generator, with
the front of the boiler removed;
Figure 2 is a side or end elevation;
Figure 3 is a top plan view of the same;
Figure 4 is a transverse section of one of the tiers comprising the settling
chamber; and
Figure 5 is a longitudinal section of the same.
1 and 2 represent two horizontal drums arranged in the same vertical plane and
connected at suitable intervals by the saddles 3-3. The ends of these drums
are provided with the usual manholes 4.
55 represent the lower series of inclined parallel water-tubes extending down-
wardly and connecting the lower forward drum 2 with a corresponding lower rear
drum 6. A similar series of water-tubes 7 connect the upper forward drum 1
with the upper rear drum 8. These rear drums and S are likewise arranged in
the same vertical plane parallel with each other, and are also provided at their
respective ends with the usual manholes 9-9.
A series of enlarged return tubes 10-10 extend horizontally rearward from the
upper front drum 1, and are then turned vertically downward and connect with
the upper rear drum 8. An alternate series of similar enlarged return tubes 12-12
lead from the upper front drum 1, and extend horizontally rearward parallel
with the first mentioned series 10-10, and are then turned horizontally down-
ward and connect with the lower rear drum 6.
13 represents the steam drum extending transversely across the tops of the
horizontal portions of the return tubes 10 and 12, to which it is connected by the
гр

page_text: saddles 14-14. The usual manholes 15 are provided in the ends of the steam
drum, and 16 represents the connection through which the steam is conducted
to the engine.
17 represents a steam pipe leading from the steam drum to the upper end of
the water gauge 18, and a short pipe leads from the gauge and enters the upper
forward drum 1 below the water level, which is shown by the dotted lines a―a
in Fig. 2.
19 represents a layer of fire-brick or other heat-resisting material extending
transversely across the upper lower of the lower series of water-tubes 5, and ex-
tending rearwardly from the lower forward drum 2 to within such a suitable
distance of the lower rear drum 6, as will leave a draft space 20 of sufficient
area to accommodate the products of combustion from the furnace. A similar
layer 21 of fire-brick extends across the upper layer of the upper series of water-
tubes 7. beginning at the upper rear drum 8 and extending forwardly to within
a suitable distance of the upper forward drum 1, to form a draft passage 22.
23 represents the settling chamber provided with a blow or mud pipe 24 com-
municating with its lowermost end, and 25 is a pipe connecting the forward end
of said chamber with the forward tier of a series of transverse boxes 26-26, each
tier communicating with the adjacent tier by an elbow coupling 27, the lower
end of the rear tier being provided with an inlet pipe 28, through which the
feed-water is admitted. 29 represents the outlet pipe from the settling chamber 23,
through which the heated and purified feed water is fed to the drum 8.
30-31 represents blow-out or mud pipes connected to the rear drums G and S.
32 represents the position of the grate-bars, 33 the bridge wall, and the arrows
show the direction or course of the heated air and gases from the furnaces to
the smoke stack 34.
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:
1. In a steam generator, the combination with the two sets of drums 1 and 2,
and 6 and 8, the drums of each set arrauged one above the other, and one set
arranged above and in advance of the other set, a series of tubes connecting re-
spectively the upper and lower drums of each set, circulating tubes 10-12 con-
nected to the rear set of drums 6-8, extending upwardly, horizontally and
forwardly, and connected with the upper drum of the forward set, a steam drum
communicating with the steam space of the tubes 10 and 12, and blow-off pipes
leading from the lower set of drums G and S, substantially as set forth.
2. In a steam generator, the combination with the drums 1 and 2, and 6 and 8,
connecting tubes 5 and 8, circulating tubes 10 and 12 connecting the drums 1, 2,
and 6-8, a steam drum communicating with the steam space of the tubes 10-12, a
band of separated but communicating feed water heaters, an inclined settlings
chamber communicating with the feed water heaters, a pipe establishing com-
munication between the settlings chamber and the lower drum 8, blow-off pipes
for the settlings chamber and the lower drums 6-8, and the inclined walls 19-21,
arranged as described.
3. A water-tube steam generator, comprising the forward horizontal drums 1
and 2 arranged in the same vertical plane and connected by the saddles 3, the
rear horizontal drums 6 and 8 mounted in the same vertical plane, a series of
inclined tubes connecting the drums 1 and 8, and 2 and 6, respectively, a series
of curved return drums 10 connecting the drums 1 and S, and an alternate
series of curved return drums 12 connected to said drum 1 and the lower rear
drum 6, a transverse steam drum 13 connected to the return drums 10 and 12,
substantially as and for the purpose set forth.
4. A steam generator comprising the drums 1-2, and 6-8, the drums of each
set arranged vertically above each other, and the front set arranged above and in
advance of the rear set, a series of tubes connecting the upper and the lower drums

page_text: of each set, and a series of independent circulating tubes 10-12, connecting the
rear set of drums with the upper drum of the front set, substantially as shown and
described.
