Improvements in and relating to the Method of and Apparatus for
Generating Steam.
I, EDWARD FALES, a citizen of the United States of America, residing at
No. 85 Purchase Street, in the County of Suffolk and State of Massachusetts, one
of the United States of America, Gentleman, 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 improvements in the method of and apparatus for
generating steam.
The object of my invention is to provide a device by which the water to he
converted into steam will be fed down from an upper chamber, into generators which
are in the path of the products of combustion, said generators being connected' with
the water chambers so that the water chamber is connected to the lower portions
of the generators and the upper portions of said generators with the water supply
or upper chamber.
In Patents granted to me in the United States of America, dated December 16th,
1890, Nos. 442,966, and 442,967, I have shown, described and claimed, a chamber
through which the products of combustion pass, inclosed by water chambers on four
sides thereof, in which is arranged a series of narrow chambers in the path of the
flame, as they emerge from the furnace, whereby the water is rapidly heated and
circulated to the other water chambers, and to the place of usage.
Referring to the drawings
Figure 1 is a longitudinal sectional view of my improved boiler.
Figure 2 is a horizontal sectional view, taken on the line, r, of Figure 1.
Figure 3 is a vertical sectional view, taken on the line y, y, of Figure 2.
Figure is an end view of the furnace, with a portion of the masonry broken
away to show the arrangement of the generators.
Figure 5 is a perspective view of one of the vertical grate bars.
Figure 6 is a view in perspective of a detachable rack for use in raising the
damper of the furnace.
Figure 7 is a view in perspective of the lever used in raising the damper.
Figure 8 is a view in perspective of one of the bents or frames to which the side
walls of the generators are secured.
Figure 9 is a detached view of the rear damper.
A, indicates the furnace, which is set in a suitable housing of brick or masonry,
aud is by preference of the form shown in the Patent granted to me in Great
Britain November 19th, 1889, No. 18502, in which the fuel is fed to the point of
combustion by gravity, said fuel being supported, together with the incandescent
fuel which is being burned, on a bed of ashes, the fuel being fed down by gravity, as
before stated, to the point where it is consumed by removing a portion of the ashes
from the lower part of the furnace or through the trench; B, which open out through
the door, C, in 'the side of the masonry, the ashes being pushed back into the trench
by a' suitable tool' inserted in the opening the air for supporting and effecting
a complete combustion being admitted throu.h the opening, E, which may be
provided with a suitable damper or door for regulating the amount of air
admitted.
:
It' will be noticed that the opening, E, is narrower at the front than at the
rear, in order that the air may be beated as it comes into the opening, and be
distributed to the fuel in the furnace. It also prevents the heat from coming
out into the room.
The rear side of the furnace, A, is provided with a sliding door or damper; F,

page_text: :
located in front of the vertical grate bars a', which is provided with a bail, G.
which projects upward through suitable openings on each side of the furnace, the
handle, or top portion being designed to rest on the top of the furnace as indicated
at a, in Figure 1..
To raise the damper, F, I employ a bifurcated lever, K, to engage the bail, G,
the fulcrum of which is the cross bar, L, so that when the damper, F, is raised
to the desired height, the bail, G, is held in place by engaging the notches of the
standard, H, and held therein chiefly by frictional contact.
M, is the main boiler or tank into which the water is admitted through the
pipe, N, from any suitable source of supply. The main boiler or tank, M, is
provided with the usual steam dome and safety valve, and connects with the
steam chest of the engine by means of suitable pipes. The main boiler or
tank, M, communicates with the horizontal water chamber, O, by means of pipes, l',
and Q, one of. cach, on each side of the tank or main boiler. The top of the
pipes, P, extend just through the bottom of the boiler or tank, M, and are
provided with nuts, b, above and below the bottom of the boiler so as to hold
the same in a rigid position; the object of these pipes, P, being flush with
or extending a short distance above the bottom of the boiler, is to supply
the chamber, O, and the generators, R, with water from the boiler or tank, M.
It will be noticed that the pipes or tubes, Q, extend some distance above the
bottom of the tank, M, as shown at e, in Figure 1, and the object of this is to allow
the air to escape from the chamber, O, into the upper portion of the tank or
boiler, M.
The generators, R, which may be of any desired number or size, do not connect
at their lower portions with the chamber, O, as they do in my Patents of the
United States, Nos. 442,966 and 442,967, first herein referred to, but are supported
a short distance above the top of the chambers, O, by tubes, which supply them with
water, which will be more fully hereinafter described.
The generators, R, are composed of two sheets of boiler or other suitable iron,
and are riveted at their edges to the frame or bent, T, so as to form a solid
structure. As before stated, the generators, R, connect the chambers, O, by means
of pipes or tubes, V, at their lower edges, and through which the proper supply
of water is furnished the generators, R. It will be understood that each generator
connects with the chamber, O, in the manner heretofore stated.
The upper portion of each generator, R, is connected to the main boiler or tank, M,
by means of the pipes or tubes, W, said tubes being projected some distance up into
the tank, M, as shown at, d, in Figure 3, whereby the steam from the generators, R, is
carried up into the steam space of the boiler or tank, M.
It will be noticed that the water space in the generators, R, is made thin and the
sides are bolted together with a number of stay bolts, and that the water is fed into
the saine at the bottom thereof, so that there is no liability to foam, and all danger
of explosion is obviated.
The rear ends of the generators, R, are provided with an enlarged portion, A',
which extends down below the main body of the same, and communicating with
this enlarged portion are pipes, B', provided with cocks or faucets, C¹, through
which the mud or other sediment is drawn from the generators.
The different spaces between the generators connect with the stack, D', by means
of flues, E, said flues being opened or closed by means of the damper, F¹, said
damper being operated by the lever, G', and adjusted to any desired point by
means of the rack bar, H. The object of having a number of flues connecting
with the stack is to more equally distribute the heat. The unions between the
generators, R, and the tank, M, are so arranged as to be easily detached, so that
they can be detached at both ends and the same removed when occasion requires ;
also the tubes, by turning the tubes downward into the chamber, O, it detaches it
from the elbow, and the upper nuts or bosses unsevered, which detaches the
tubes from the generators, and each generator can be taken out for repair.
!', are fenders or break-waters, located around the four sides of the tank or

page_text: boiler, M, which turn the heat to the center of the tank, M, and prevent the hot
water from being blown out too rapidly from the generators.
The chamber, O, is also provided with a blow off pipe through which the mud
and sediment is removed from said chamber.
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 :-
1. The method herein described of generating steam which consists in feeding
the water from an elevated tank or boiler, down and into steam generating chambers
located in the path of the products of combustion.
2. In a device for generating steam, an upper boiler or tank in which the steam
is used for beating and engine purposes, said boiler or tank connecting with a lower
steam generating chamber, and with a series of said steam generating chambers, in
the manner and for the purpose set forth.
3. In a steam generating and heating device an upper chamber or boiler in
which the water and steam is stored, said chamber or boiler communicating with a
lower water chamber by means of pipes or tubes the tops of which are slightly
above the bottom of the boiler, and other tubes which also connect the lower water
chamber with the boiler, the last mentioned tubes being projected up into the
boiler above the ends of the first mentioned pipes or tubes, whereby the lower
chamber is freed from air upon the introduction of water into the said upper
chamber, as set forth.
4. In a steam generating and heating device, an upper chamber or boiler
connecting directly with a lower water chamber, and a series of steam generating
chambers connecting with the lower water chamber and with the boiler by means
of pipes at the bottom and top of such generators, whereby the water is admitted
to the lower part of said generators from the chamber, O, and the steam through
the upper pipes to the boiler or chamber, M, as set forth.
5. In a device for generating steam, a series of vertical generators, located in
the path of the products of combustion, and separating the same into channels or
flues, each of said generators being provided with a depressed portion at their rear
ends, which connect with the blow-off pipes, to relieve the same of mud and sediment,
as set forth.
6. In a device for generating steam, a series of generators located in the path of the
products of combustion, a series of converging flues communicating with the spaces
between the generators and with the stack and a controlling chamber, all arranged
as set forth.
