Improvements in Steam Generators.
I, EDWARD PETER WAGGONER, of No. 715 East Fayette Street, in the City of
Syracuse, County of Onondaga, and State of New York, United States of America,
Mechanical Engineer, 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 Generators or heaters particularly
applicable for house-heating purposes, and has for its object the production of a
device, which is economically manufactured, is readily handled and assembled,
facilitates a positive and rapid circulation of the heating fluid, and is durable and
effective in use; and to this end, the invention consists, in the combination, con-
struction and arrangement of the component parts of a generator, all as hereinafter
fully described and pointed out in the claims. In describing this invention,
reference is had to the accompanying drawing, forming a part of this specification,
in which like letters indicate corresponding parts in all the views.
Figures 1 and 2 are, respectively, front and rear perspectives of my improved
generator.
Figure 3 is a longitudinal vertical section, taken on line 3-3, Figure 1.
Figure 4 is a perspective view illustrating the detached upright sections of my
generator as somewhat separated.
Figure 5 is a perspective of the detached base of my generator; and
Figures 6 and 7 are perspective views of modified forms of my generator.
A A1 A2 A3 A' are a series of upright sections arranged one in advance of the
other for forming the main body of the generator; B is a base upon which said
sections are mounted; C D are chambers secured respectively to the front and rear
walls of the sections A. A', and EF are suitable inlets and outlet fluid-pipes
connected to said sections in any desired manner. The top and bottom walls of said
upright sections are preferably formed substantially convex, being curved or de-
flected in opposite directions from substantially their central portions towards each
other and the longitudinal centre of the generator, and the outer faces of the top
and bottom walls of a number of said sections are substantially smooth and con-
tinuous or unbroken. The outer faces of the lower extremities of the upright
sections, are usually provided with shoulders extending lengthwise of the
generator for engaging the base B, presently described. The front and rear walls
of the sections A A¹ A³ A³ A, are usually provided with interlocking tongues and
grooves a a¹, are formed substantially flat, and are firmly secured together by
bolts A5 passed through said sections and connections or tubes, presently described,
for connecting said sections.
The upper and lower portions of said front and rear walls preferably decrease
in width towards their top and bottom edges, which are usually rounded. The
sections A A¹ A2 A3 A4 are provided with substantially centrally arranged upper
and lower fluid-openings a a³ in their front and rear walls, which openings form
water-passages extending lengthwise of the generator, facilitate a circulation in the

page_text: generator, and are usually formed respectively in substantially the uppermost and
lowermost portions of the extremities of said sections when constructed as just
described. The fluid-chambers in said sections form the heating chamber of the
generator, and extend downwardly and outwardly from the openings a³, and up-
wardly and outwardly from the openings a³. The corresponding upper and lower
openings as a³ of adjacent upright sections of my generator are connected together
by any suitable means, and preferably by short tubes or pipes G having their
opposite ends suitably fixed or secured within said openings. Sections of this
construction are readily handled, owing to their curved faces, present a large
amount of heating surface with a minimum weight of the material composing their
enclosing walls, and produce a particularly practical and effective circulation of
the fluid within the generator.
The upright sections A A¹ A2 A3 are preferably formed with passages or open-
ings in their lower extremities extending lengthwise of the generator above the
fluid-openings a³ and the lower end-walls of said sections A A A² A³, for forming
the bottom and side walls of the ash-pit A6, and the side walls and top of the com-
bustion-chamber A'; and, owing to the preferable construction of the lower ex-
tremities of the sections A A A A³, the side walls of said ash-pit A and combustion-
chamber A incline or curve downwardly. As best seen in Figures 3 and 4, the
top walls of said passages or openings in the lower extremities of the
sections A A¹ A3 A3 are provided with lengthwise corrugations a*, which form the
top wall of the combustion-chamber A7. The portions of the sections A A¹A³ Ã³
forming the bottom and side walls of the ash-pit A and the side walls of the
combustion-chamber preferably consist of substantially U shaped fluid-chambers,
connected together by the openings a³, and opening into the connected chambers
chambers preferably suppont a suitable grate H for separating the ash-pit and the
in the upper extremities of said sections. The inner walls of said U shaped
combustion-chamber.
my
Suitable upper and lower passages or openings extend lengthwise of
improved generator through the fluid-chambers in the upper extremities of the
sections A A A³ A³ A* and beneath the fluid-openings a³, and the adjacent ends
of corresponding passages or openings are aligned with each other and arranged
in close proximity to each other for forming continuous or closed upper and lower
flues A8 Aº. A fire-passage A10 extends downwardly in the section A from the
rear end of the lower flues A towards the combustion-chamber A', and the front
ends of said upper and lower flues are usually connected as presently described.
As best seen at Figure 4, the sections A A¹ AAA are preferably provided with
a number of upper and lower flues A8 A" and the lower portions of the rear ends
of the flues A are cut away for forming a comparatively large chamber, which is
provided with a rear outlet-passage a5 and greatly facilitates the passage of the
products of combustion from the fire-passage A10 into the flues A. The lower end
of the fire-passage A10 is connected to the upper portion of the rear end of the
combustion-chamber A' by a fire-passage A" extending through the section A³,
which is arranged in front of the section A', and is provided with a bridge-wall A¹³
preferably formed hollow and arranged at the rear of the combustion-chamber A
beneath the fire-passage A". The water-containing chamber of the rear section A*
preferably extends only a limited distance beneath the fire-passage A10 and the top
edge of the bridge-wall A, and an opening A¹³ is formed in said section A' at
the rear of the bridge-wall A2 for decreasing the weight of said section. It is
obvious, however, that this opening A3 may be dispensed with if desired.
The base B, which may consist of a single piece or several sections arranged
end to end, extends from front to rear of the generator beneath the sections
A A¹ As A³ A+. The upper face of said base has a lengthwise groove therein, is
preferably formed concave, and is provided with separated longitudinal bearing
surfaces 6 6 inclined downwardly towards each other. The outer faces of the lower
ends of said sections are normally engaged with the surfaces 66 and the central
portions of said faces extend downwardly beneath the surfaces b b and into the

page_text: lengthwise groove formed in the upper face of the base B. The chamber O
connects the front ends of the flues A8 A9, and the chamber D, connects the rear
ends of the flues A8 and the outlet a5 to a draft-conduit or pipe d. Suitable.
dampers may be arranged, respectively, in the chamber I), and the conduit d
for varying the path and the draft of the products of combustion.
It will be readily apparent that, although the ash-pit of my generator is usually
enclosed, as described, by U shaped water-containing chambers at the lower ex-
tremities of the upright sections of the generator, it may be otherwise formed if
desired. I have, therefore, illustrated in Figure 6, a modified construction of my
invention, in which each section is formed with separated inlet-connections 10
arranged on opposite sides of the base of the combustion-chamber all, and is provided
with separable base-portions at which are formed U shaped in cross section,
enclose the ash-pit a¹³, and are suitably secured to the top portions of said sections.
In Figure 7 I have shown a further modified form of my invention, in which the
ash-pit a is enclosed by a common base-portion or continuous Ushaped wall a
arranged beneath sections a² of similar construction to the upper and central
portions of the upright sections of the preferable form of my invention.
The operation of my improved generator will now be readily understood upon
reference to the foregoing description and the accompanying drawing, and it will
be particularly noted that I do not herein specifically limit myself to the exact
detail construction and arrangement of its component parts, as the same may
obviously be varied without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of this said in-
vention, and in what manner the same is to be performed, I declare that what I
