J., WILLIAM ROBERT LAKE of the firm of Haseltine Lake, & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, 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 improvements in steam heaters for heating dwellings,
factories and the like and consists essentially in providing a simple, effective, and
easily regulated magazine steam heater, whereby the fuel required for the generation
of steam may be filled into the magazine, and the furnace of the heater controlled by
means of draft dampers operating automatically by the steam pressure,
after more particularly described.
all as herein-
In describing the invention reference is had to the accompanying drawings in which
like letters of reference indicate corresponding parts in all the views.
Figure 1 is an elevation of the improved heater set up and trimmed for. use,
illustrating the general construction and arrangement of the parts, as seen from the
exterior of the heater, it being noted that the smoke pipe connections and steam
supply pipes to the radiator system of the building are not shown connected to the
heater.
Figure 2 is a view of the improved heater with the outer jacket removed illustrating
the various sections, of which the parts of the heater are constructed set up or
assembled in their operative position ready for the exterior jacket and trimmings...
Figure 3 is a transverse vertical section illustrating more particularly the interior
construction and arrangement of the various parts of the improved heater, illustrating
also the water connection between the sections and the fire-flues and drafts through
which the products of combustion pass as they circulate from the fire-pot of the heater
upward and onward to the smoke pipe.

page_text: Figure 4 is a detached top plan of the top of the heater, showing the magazine-
hood and cover to the magazine, illustrating also the detail features of construction
of those parts.
Figure 5 is a detached horizontal section of the lower section of the improved
heater illustrating the water space in said section, and also the enlargements through
which pass the bolts or rods serving to connect the various sections of the heater in
their operative position.
Figure 6 shows one of the door sections detached in plan view, and partly in section
illustrating the construction of such section.
Figure 7 illustrates a like section showing corrugations on the inner side or edge
thereof, said corrugations increasing the heating surface, and at the same time simpli-
fying the casting or moulding of the section.
Figure 8 shows a central section, which, as the heater is made up is mounted on the
corrugated section shown in figure 7.
Figure 9 is a detached inverted bottom plan view of the top section of the heater
comprising and including also the magazine-hood, and
Figure 10 is a detached top plan view of the upper part of the base illustrating
the grate of the heater.
It will be observed from the description of the drawings that the improved heater
is composed of sections preferably moulded or cast, and the peculiar features of
construction as illustrated in the drawings make the sections very simple to cast and
at the same time obviate the riveted construction of wrought iron sheets, which have
heretofore been employed in heaters for domestic purposes, whereby great liability of
explosion existed through carelessness; or a lack of proper understanding of the
attending and running of that form of heaters. Moreover the illustrated construction
provides fully for the expansion and contraction of the metal without causing the
joints to leak, and the result is that great durability is secured aside from the perfect
safety of the device from dangerous explosions.
P
A denotes the base of the heater, which contains the ash-pit, and is provided with a
suitable door a for removal of the ashes and the draft door a¹ which is operated auto-
matically by means presently described. On the base A of the heater is mounted the
section 1 which is provided with projections p, p, p, Figure 5 having suitable bosses
cast in said projections in which tie-rods T, T, are secured and serve to connect the
sections one upon the other. The lower section 1 as will be observed upon reference
to figure 3 of the drawing is of less diameter than the other sections superimposed
thereon for a purpose presently explained, and is also provided with the water space w
shown by the dotted lines. Mounted on section 1 is the door section 2, best shown in
the detached plan view figure 6, the said section 2 being provided with water
spaces w, w¹ the inner space w coinciding with the water space of section 1, while
the outer space w¹ projects beyond the space was best shown in the sectional view,
figure 3, and the section 2 figure 6 is provided with the door opening C, which affords
access into the fire-pot and combustion chamber of the heater.
Immediately above the section 2 is mounted the castisection 3, figure 7, the said
section being provided also with coincident water spaces w w¹ which coincide with the
like spaces in section 2. The section 3 is also provided with a door space C", which
coincides with the door space C of section 2, and the two door spaces C, C¹ constitute
the door opening for the. door B, figures 1 and 2, which affords access to the fire-
pot and combustion chamber of the heater. The interior edge of the section 3 is
corrugated as shown for the purpose of increasing the heating surface as well as
facilitating the casting of such sections. Mounted on top of section 3 are two
sections 4 provided with coincident water spaces w, w, and the interior corrugations
corresponding to the corrugations on section 3, and the top section 6 supporting the
hood for the magazine together with the feed door is mounted on top of the upper
section 4, or what really constitutes the fifth section of the heater. The upper
section 6 is provided with a downwardly projecting flange 5 as best shown in figures 2
and 3 which serve to raise the circular dome R¹ above the upper section 4 of the heater.
The various sections of the heater are provided with packing surfaces or flanges E,

page_text: which are coincident with each other, and which coincide with the three extensions p, p
of section 1, and the said flanges are faced off and packed with an asbestos gasket,
which makes a tight joint between said sections, while the tie-rods T securely connects
the said sections together. It will be observed that the fire-pot is formed by the
space within the rings cr sections 1 and 2 ; also that the sections are hollow and that
the space within the rings of sections 1 and 2 constitutes the fire-pot, which comes
above the grate. G mounted in the top A¹ of the base A. The grate G is composed of
rotatable grate-bars suitably connected so as to be actuated by the crank G¹ simul-
taneously for the purpose of shaking or cleaning out the clinkers from the fire-pot
without interfering with the fire.
It will also he observed that the various sections above the first section are provided
with flues f, which are coincident with each other, and extend one above the other
affording a passage for the products of combustion from the fire-pot up through the
horizontal circular dome R¹ of the upper section from whence, they pass into the
smoke or exit pipe S.
The magazine M is cast separately and inserted down through the corrugated space
in the rings or sections 3-4-4 and 6, and best shown. in figure 3, and it discharges
at its lower end directly into the fire-pot over the grate.G. "It will be observed that
by reason of the corrugations, the products of combustion pass upwardly between the
corrugated surfaces thoroughly heating the same, and that the heating surface of the
sections above the plain section 2 is thereby greatly increased, and the generation of
steam thereby greatly facilitated. The hood H of the magazine M is mounted on top
of the section 6, and is provided with the extended slanting chute or opening H¹,
through which the fuel is supplied to the magazine M, and the arrangement thereof
in the manner shown greatly facilitates the feeding of the magazine, at the saine time
obviating the necessity for inserting the charge at the top of the hood.
b
In order to prevent the products of combustion from ascending directly to the exit
pipe or uptake flue S, the baffle plate figure 2 is provided on the exterior of section
or ring 3, said baffle plate extending outward circumferentially so as to close the
passage between the casing I; figure 3, and by reason of the said baffle plate, the
products of combustion are compelled to pass down in the direction of the arrows, as
best shown in figure 3 through the space L formed by contracting the lower section 1
as described, from thence into the space between the inner jacket and casting thence
around the flange 5 and finally into the uptake flue S to the smoke or exit pipe.
Suitable dampers d are provided for the purpose of providing a direct and indirect
draft the operation of which will be readily understood upon reference to Figure 3 of
the drawing. The water supply pipe P for the heater is, connected to the water
space w of the lower section, as best shown in the detached sectional view Figure 5,
and the steam supply pipe is connected with the dome R¹ of the boiler and steam
drawn therefrom to the radiator system of the building to be heated.
The safety valve s is connected with the dome and provided with a ball weight st
while the regulator N is connected to the dome and provided with the lever Ŏ and
chains o, o which are connected to the check draft and draft door a¹ in the base of the
heater and serve to automatically control the draft of the furnace by the variation of
the steam pressure. The contracted lower section 1 provides the space L beneath the
section 2 and the flues f open into said space, which is provided with opening Li
through the outer casing J affording convenient access to the space L whereby the
dust from the products of combustion which pass through the fire flues may be
removed without difficulty when it is desirable to clean the aforesaid flues and the said
flues are provided with caps f2 in the top of the heater which may be removed and
a flue cleaner inserted for the purpose of cleaning the said flues.
It is to be noted that the independent sections 1, 2, 3, 4 of which the generator is
made up overcome the tendency to dangerous explosions incidental to the use of the
old forms of steam heating apparatus, while at the same time the "interchangeable
system " of manufacture is secured by this feature of construction, whereby any
section giving out may be readily replaced without difficulty. The joints E between
the sections are faced off and packed as described with an asbestos gasket which

page_text: insures tight joints without leakage being caused by the contraction or expansion of
the metal since the elastic quality of the gasket adapts it to the varying conditions
of the metal, and thus secures the desired result.
The two jackets I, J constitute a double casing or shell for the heater with an air
space between the two jackets which serves to prevent radiation on the exterior of the
heater. All of the parts of the improved heater are formed of suitable shape to secure
the best results in casting them and at the same time to overcome all difficulty in
moulding.
In the operation of the improved steam lieater the products of combustion pass up
through the centre of the heater, turn outward at the dome and descend through the fire
flues and then ascend on the outside between the water sections and jackets, being
forced to take this direction by reason of the interposition of the baffle-plates b which
are placed as previously described and serve to turn the heat to the front and then
back into the chimney thus causing the products of combustion to impinge and
traverse the entire heating surface and utilizing all parts of the heater as effective
heating surface, furthermore, by providing the door B which is made flaring or wide
mouthed plenty of air is admitted for surface burning, which secures great economy
in the consumption of fuel while the magazine M makes the apparatus self feeding
obviating the necessity of constant watching and attendance to keep up steam.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents I declare that what I claim is :-
First. A steam beater for domestic heating, composed of independent interchange-
able sections superimposed one upon the other, said sections having water spaces and
return fire-flues, a self feeding magazine made of a separate casting and a fuel chute
extending from the rim of the top of the heater outwardly all substantially as
specified.
Second. The within described sectional heater having its lower section of lesser
diameter than that of the succeeding upper sections and an opening in the outer
casing into the space formed by contracting the diameter of said lower section,
substantially as and for the purpose set forth.
Third. The combination of the plain and corrugated sections 1; 2, 3, 4 with the
magazine M the dome R', the automatic dampers and the regulator N operated by
steam pressure, all substantially as and for the purpose set forth.
