Improvements in Steam Generators and Water Heaters.
I, JOSEPH ALEXANDER IRÉNÉE CLAUDON, resident of 713, Eight Street,.
Glenwood Springs, in the County of Garfield, and State of Colorado, United
States of America, 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 sectional tubular steam boilers and water heaters, and
its object is to provide an improved construction of the same which shall possess
superior advantages with respect to efficiency in use.
The invention consists in the novel construction and combination of parts herein-
after fully described and claimed.
In the accompanying drawings:
Figure 1 is a central longitudinal section of a steam boiler constructed in
accordance with my invention.
Fig. 2 is a front end view, Fig. 3 is a similar view, the cast iron front being
removed.
Fig. 4 is a perspective view of the water-jacket, detached.
In the said drawings the reference numeral 1 designates the casing of the
generator or heater, being shown in the present instance as composed of fire-brick,
although it may be made of cast-iron, or other material, if desired. The front of
this casing consists of a cast iron plate or plates, 2, provided with doors 3 for
cleaning out purposes, a door 4 leading to the fire-box, and an ash-pit door 5.
Located in the upper portion of the casing are a number of water-pipe sections,
(five being shown in the present instance,) each consisting of a series of slightly
inclined longitudinal water-tubes 6 connected at their rear ends to vertical
manifolds 7, which in turn communicate by means of pipe 8, with a steam dome 10,
provided with flow-pipes 12. At their front ends these tubes 6 are provided with
elbows 13 with which are connected vertical tubes 14; the lower ends of which are
connected with inclined manifolds 15, approximately triangular in cross section.
Set in the masonry of the casing, and supported thereby, is a rectangular water-
jacket 16, the inner walls of which form the sides of the fire-box. The front of
this jacket is formed with an opening 17, which is closed by the fire-door. The
upper front side of the water-jacket is conuected with the front manifolds 15, by
means of elbows 18, and nipples 19. At the lower front end the jacket is provided
with holes 20 provided with sockets 21 in which fit removable screw-plugs 22; the
object of the holes or openings being to remove sediment from the jacket. There
are also holes at the sides of the jacket near the lower part thereof, with which are
connected return tubes 23 connected with the return pipes of the radiators. When
used as a water heater one of these return tubes may be connected with an elevated
tank, (not shown) by which water is supplied to the jacket. The inner walls of the
jacket are corrugated, as shown, so as to afford an extended fire surface.
The numeral 24 designates the grates.
The operation is as follows: The tubes and water-jacket are supplied with water
and a fire started in the fire-box heating the water in the water-jacket, and the
products of combustion passing around and between the front manifolds and the
water-tubes will impart a high heat thereto whereby steam is quickly generated
which passes off to the steam-dome. It will be noted that the wall 25, of the
furnace, below the horizontal tubes extends from the fire-box to near the rear end

page_text: of the casing forming a flue 26 leading to the chamber 27. After the products of
combustion pass between and around the water-tubes, they escape through flue 26
down to the chamber 27, and from thence through exit-flue 28 to the smoke-stack,
(not shown).
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. In a sectional steam generator or water-heater, the combination with the
inclined horizontal water-tubes, the rear vertical manifolds connected therewith,
the vertical water-tubes connected with the front ends of said inclined tubes and
the inclined manifolds with which said vertical tubes are connected, of the water-
jacket forming the sides of the fire-box, having openings in its sides at the lower
end, the return tubes connected therewith, the removable screw-plugs, and the
nipples connecting the front manifolds with the water-jacket, substantially as
described.
2. In a sectional steam boiler or water heater, the combination with the water-
tubes, the upper and lower manifolds, and the water-jacket connected with said
lower manifolds, having corrugated inner walls, of the casing the fire-box, the
horizontal wall extending from the fire box to near the rear end of the casing
forming a flue at said end, the chamber below said wall and the exit flue at the rear
end of the casing below said horizontal wall, substantially as described.
Dated this 17th day of March 1896.
