Improvements in Steam Generators, and in the Furnaces used in
connection therewith.
I, SAMUEL EDGAR SNEDEKER, residing at 11, Hillside Avenue, White Plains,
in the County of Westchester, and State of New York, United States of America,
Bank Clerk, do hereby declare the nature of this invention to be as follows: —
This invention relates to steam generators, and the object thereof is to provide
an improved apparatus for this purpose which is simple in construction and opera-
tion, and by means of which steam may be quickly and easily generated with a
less consumption of fuel than usual in this class of devices.
In the practice of my invention I provide a furnace which comprises a back
wall, a bottom wall, and a central upright buffer wall,
in front of
which is placed the grate, and the furnace is also provided with a top or cover,
and a front wall in which is placed the usual door or doors, and below the grate
is the usual ash receiving chamber.
The furnace may be composed of any desired material, and extending downwardly
and backwardly from the top thereof to the rear of the buffer wall is a transverse
partition with which is connected backwardly directed horizontal partition plates
which extend backwardly to within a short distance from the back wall of the
furnace and the back wall of the furnace is provided with corresponding partition
plates which extend forwardly in the direction of the transverse partition, and
which are arranged between the first named partition plates.
The water supply of the steam generator consists of a vessel of any desired form
or construction, which is preferably arranged over the back wall of the furnace,
and is provided with a supply pipe which communicates therewith, and connected
with said vessel is a pipe which extends downwardly and forwardly, and is coiled
backwardly and forwardly between said horizontal partition plates and carried
downwardly beneath the bottom of said transverse partition plate and upwardly
over the buffer wall, and is then formed into or connected with a plurality of
vertical coils which occupy the space over the grate, and the end thereof is carried
upwardly through the top of the furnace, and connected with a steam drum.
Connected with said pipe at the point where it passes beneath said transverse
partition plate, is a mud drum, and said mud drum is provided at one end with a
discharge pipe in which is placed a suitable valve, and it will be understood that
any desired number of the pipes which connect the water supply with the vertical
coils may be employed, as may also any desired number of said coils.
My improved steam generating apparatus is simple in construction and opera-
tion, and by means thereof steam may be almost instantly generated, the position
of the coils over the grate facilitating this operation, and it will also be observed

page_text: that the water is highly heated before it enters said coils, or as it passes through
the pipe or pipes by means of which said coils are connected with the water supply.

Improvements in Steam Generators, and in the Furnaces used in
connection therewith.
I, SAMUEL EDGAR SNEDEKER, residing at 11, Hillside Avenue, of White Plains,
in the County of Westchester, and State of New York, United States of America,
Bank Clerk, 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: --
This invention relates to steam generators, and the object thereof, is to provide
an improved apparatus for this purpose which is simple in construction and opera-
tion, and by means of which steam may be quickly and easily generated with a
less consumption of heat than usual in this class of devices; and with this, and
other objects in view, the invention consists in the construction, combination and
arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which:-
Fig. 1, is a central, longitudinal vertical section of my improved steam generator;
and,
Fig. 2, a partial plan view thereof.
In the drawing forming part of this specification, the separate parts of my
improvement are designated by the same numerals of reference in each of the
views, and in said drawing, I have shown a furnace, which comprises a back
wall 5, a bottom wall 6, a central upright buffer wall 7, in front of which is placed
the grate 8, and the furnace is provided with a top 9, and a front wall 10, in which
is placed a door 11, and below the grate 8, is an ash receiving chamber 12.
The furnace may be composed of any desired material, and extending down-
wardly and backwardly from the top 9, thereof, to the rear of the buffer wall 7, is a
transverse partition 13, with which is connected backwardly directed horizontal
partition plates 14, two of which are shown, and these partition plates 14, extend
backwardly to within a pre-determined distance from the back wall of
the furnace, and the back wall 5, of the furnace, is provided with
corresponding partition plates 15, which extend forwardly in the direction of
the transverse partition 13, and which are arranged above and below the lower
partition plate 14.
The water supply of the steam generator consists of a vessel 16, of any desired
form or construction which is preferably arranged directly over the upper portion of
the rear wall 5, of the furnace, and is provided with a supply pipe 17, which com-
municates therewith, and connected with said vessel 16, is a pipe 18, which extends
downwardly and forwardly, and is coiled backwardly and forwardly between the
partition plates 14, and 15, and carried beneath the bottom of the transverse
partition plate 13, and upwardly over the buffer walls 7, and is then formed into
or connected with a plurality of vertical coils 19, which occupy the space over the
grate, and the end thereof, is carried upwardly through the top of the furnace
and connected with a steam drum 20.

page_text: Connected with the lower point of the pipe 18, within the rear portion of the
furnace and directly beneath the lower side of the transverse partition plate 13,
is a mud drum 21, and said mud drum is provided at one end with a discharge
pipe 22, in which is placed a suitable valve."
It will be understood that a plurality of pipes 18, and the coils 19, may be
employed, and that each of said pipes and said coils will be connected with the
water supply vessel 16, and with the steam drum 20, as herein shown and described,
and said steam drum is provided with the usual steam pipe 23.
This apparatus is simple in construction and operation, and by means thereof,
steam may be almost instantly generated, the position of the ccils 19, facilitating
this operation, and it will also be observed that the water is highly heated in the
separate coils of the pipe 18, in the rear portion of the furnace, before it reaches
the coils 19, which are directly over the grate.
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. A steam generator, comprising a furnace, which is provided at the front
thereof, with a grate, and rearwardly of said grate with a transverse buffer wall,
said furnace being also provided with a downwardly and backwardly directed
partition rearwardly of said,buffer wall, and with horizontal partition plates which
extend backwardly toward the rear wall of the furnace, and with corresponding
partition plates which extend forwardly from the rear wall of the furnace a water
supply drum or vessel mounted over the rear portion of the furnace, a pipe con-
nected therewith and coiled back and forth longitudinally of the rear portion of
the furnace between said partition plates, said pipe being carried downwardly
beneath said transverse partition, and then upwardly over said buffer wall, and
formed in coils over the grate, said coils being in communication with a steam
drum, substantially as shown and described.
2. A steam generator, comprising a furnace which is provided at the front
thereof, with a grate, and rearwardly of said grate with a transverse buffer wall,
said furnace being also provided with a downwardly and backwardly directed
partition rearwardly of said buffer wall, and with horizontal partition plates which
extend backwardly towards the rear wall of the furnace, and with corresponding
partition plates which extend forwardly from the rear wall of the furnace a water
supply drum or vessel mounted over the rear wall of the furnace, a pipe connected
therewith and coiled back and forth longitudinally of the rear portion of the
furnace between said partition plates, said pipe being carried
wardly beneath said transverse partition, and then upwardly over said buffer wall,
and formed in coils over the grate, said coils being in communication with a steam
drum, and the pipe in the rear portion of the furnace being provided below said
transverse partition with a mud drum which is in communication therewith,
substantially as shown and described.
