Improvements in Steam Generators
Year: 1897

page_text: I, DEYO SAMUEL WORDEN, of the Village of East Penfield, County of Monroe,
and State of New York, United States of America, Navigator, 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 Generators, and has for its
object the production of a device which is economically manufactured, is readily
assembled and repaired, and is particularly effective and durable in use; and, to
this end, the invention consists, essentially, in the combination, construction and
arrangement of the component parts of a steam-generator, all as hereinafter
more particularly 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.
Figure 1 is a front elevation of this improved steam-generator, the front section
of the enclosing shell or jacket being removed for disclosing the interior
construction.
Figure 2 is a vertical section, taken on line 2-2, Figure 1.
Figures 3, 4 and 5, are horizontal sections, taken respectively, on lines 3-3,
4-4 and 5-5, Figure 1; and
Figure 6 is a perspective view of the detached grate-support.
A is a drum supported above the combustion-chamber B of this improved steam-
generator, and C C C², are upright heads arranged at the side of said combustion-
chamber. The drum A is preferably cylindrical and of greater length than
diameter, is arranged in a substantially vertical plane, and is provided with blow-
off and steam-discharge pipes a a' communicating with its upper and lower ends.
The heads C C Care of suitable size, are preferably arranged in a substantially
circular series, and are usually utilized to form the upright wall of the combustion-
chamber B. None of the heads C C C³ are arranged directly in front of the
combustion-chamber B, as best seen at Figure 1, in order that said combustion-
chamber and the ash-box B beneath the same may be readily accessible through
openings in the enclosing shell or jacket, presently described. Additional
heads are preferably arranged above the plane of the combustion-chamber B at
the front side of the drum A, and their opposite extremities are connected to the
upper and lower ends of said drum.
The drum A is connected to the heads C C¹ C² by suitable fluid-connections or
pipes c c which usually extend laterally from said drum and heads, and are
arranged one above the other, thus obviating undue weakening of the shell of the
drum A and facilitating the practical operation and repair of the generator. The
heads CC1 C2 extend upwardly, respectively, to the base, the intermediate portion,
and the top of the drum A, and the fluid-connections c c¹ c² extend laterally from
the upper extremities of said heads and are connected respectively to the base, the

page_text: intermediate portion, and the top of the drum A. The fluid-connections are
arranged beneath the fluid-connections and are interposed between the inter-
mediate portions of the heads C and the base of the drum A; and in order to
facilitate securement of the connections, said heads C2 are generally composed of
upper and lower sections detachably secured together.
This improved generator, having its drum A and its head C.C1 C2 arranged and
connected as described, is particularly durable and efficient, since the parts expand
and contract freely, and the water circulates in short substantially upright paths,
and passes both downwardly and upwardly from the base of the drum through
said heads. The efficiency of the generator is additionally increased by tubes D
which are formed with closed outer ends, and project laterally from the drum A
above the connections c c¹³ and below the connections cc. The outer ends of
the pipes D are preferably contracted for obviating the accumulation of sediment
therein.
The lower ends of the heads C C C² may be suitably connected, but preferably
project upwardly from a water-containing base E with which this improved
generator is provided. The base E is usually formed by top and bottom plates e e¹
having depending flanges eat their outer edges which extend beneath the
lower face of the bottom plate e¹ and are suitably secured together by rivets e¹. A
base of this construction is economically formed, since it consists of but
plates, one of which forms both the top and upright walls thereof, and such a base
is particularly durable as both plates are secured together at a point beneath the
water-line in the base, thus obviating undue expansion of the joint between said
plates.
iwo
This improved steam generator is provided with an enclosing shell or jacket F
consisting preferably of vertical front and rear sections of f¹ "detachably secured
together at their adjacent edges and provided with converging upper ends formed
with a smoke-outlet f. The shell or jacket F is preferably provided with an
asbestos-lining and its lower end surrounds the base E and rests upon the
rivets c. Suitable openings f* f are formed in the shell or jacket F for permitting
access to the combustion-chamber B and the ash-box B', and these openings are
closed by doors f f as best seen at Figure 2.
The grate G for this improved steam-generator may be of any suitable con-
struction, and is here illustrated, as consisting of separable sections for facilitating
its securement and removal. This grate is preferally mounted upon a support G¹
which is of less height than the opening in the shell F and consists of a split
ring provided with detachable feet gl normally mounted on the base E, and having
its opposite ends detachably secured together by suitable fastening means g. A
grate-support of this construction, is readily withdrawn through the opening ft by
separating its adjacent ends, passing one end through said opening, and turning
the support until the opposite end is withdrawn. This improved steam-generator
is also provided with a suitable pressure-gauge h, a water-glass and a feed-
pipe, which formi no part of this present invention and are not herein specifically
illustrated and described.
The operation of this improved steam-generator will now be readily understood
upon reference to the foregoing description and the accompanying drawing, and it
will be obvious to those skilled in the art that this invention is not limited to the
exact construction and arrangement of the component parts of said generator.
