UNITED STATES PATENT -OFFICE.
WILLIAM DAMM, OF SAN ANTONIO, TEXAS.
WATER-HEATER.
SPECIFICATION forming part of Letters Patent No. 735,069, dated August 4, 1903.
Application filed December 23, 1902. Serial No. 136,407. (No model.)To all Whom it tmay conce7rf:
Be it known that I, WILLIAM DAMM, a citi-
zen of the United States, residing at San An-
tonio, in the county of Bexar and State of
5 Texas, have invented a new and useful Wa-
ter-IHeater, of which the following is a speci-
fication.
This invention relates to water-heaters; and
it has for its object to provide a device of this
1 o class which may be constructed at a moderate
expense and which shall be efficient for the
rapid heating of water in such localities as
barber-shops, bath-rooms, and the like, where
a large boiler would be too expensive and
15 cumbersome, but where at the same time it is
necessary that a constant supply of hot water
shall be at hand.
The principal object of my invention is to
provide a device of this class which shall be
20 so simple in its construction that it may be
operated by any previously unskilled person
and which shall in all respects possess the ad-
vantages of simplicity, durability, and gen-
eral efficiency.
25 With these ends in view the invention con-
sists in the improved construction, arrange-
ment, and combination of parts, which will be
hereinafter fully described, and particularly
pointed out in the claims.
3o In the accompanying drawings, Figure 1 is
a vertical sectional view of a water-heater
constructed in accordance with the principles
of my invention. Fig. 2 is a top plan view.
Corresponding parts in both figures are in-
35 dicated by similar numerals.
A suitable base 1 is provided, having a cen-
tral recess 2, constituting an ash-pit, and this
base is provided on its upper side with a hori-
zontal flange 3, surrounding the ash-pit, and
40 with an outer annular flange 4. A grate 18
is supported within the ash-pit, at the upper
edge of the latter.
The body of my improved water-heater is
composed of a single casting comprising an
45 exterior cylinder 10, connected at its lower
edge by a flange 5 with an interior upwardly
and inwardly tapering drum 11, provided at
its upper edge with an annular inwardly-ex-
tending flange 14. Alining openings in the
5o outer cylinder 10 and the inner drum 11 are
connected by a flange 6, thus forming a fuel-
feed opening, at the outer end of which isprovided a hinged door 21. The cylinder 10
is provided at its upper edge with an exterior
annular flange 7, which is in horizontal aline- 55
ment with the flange 14 of the drum 11, and
a cover 12, which forms a closure for the wa-
ter-space 8 between the cylinder 10 and the
drum 11, is connected by bolts 13 or other suit-
able means with the flanges 7 and 14 at the 6o
upper ends of the said cylinder and drum.
The flange 14 has been described as annular,
thereby implying the existence of a central
opening 9, in alinement with which a collar
12 is formed upon the cover-plate 12, said 65
collar being for the purpose of supporting a
pipe or stack 15 for the escape of the products
of combustion.
The exterior cylinder of the device is pro-
vided with flanged openings on opposite sides 70
thereof, which are suitably connected with
pipes 19 and 20 for the exit and admission of
water to the interior of the water-space 8, and
with additional pipes 22 and 23, by means of
which a circulation may when desired be es- 75
tablished in a tank or reservoir suitably con-
structed and located.
It will be observed from the foregoing de-
scription that the part of the device which
constitutes the combustion-chamber and the 8o
water-space is a single casting provided only
with a detachable cover and a hinged door
closing an opening through which fuel may
be fed into the said combustion - chamber.
This device is supported upon a single cast- 85
ing, which constitutes the ash-pit and with
which the grate may or may not be integral.
The cover-plate is provided with the collar
with which the stovepipe is connected.
The operation of the device is obvious. 90
When it has been set up for operation, a fire
is started in the combustion - chamber, the
walls of which extend the entire height of the
water-space, thus subjecting the water con-
tained therein to an intense degree of heat, 95
whereby the temperature thereof will be rap-
idly raised.. The construction is.one of ex-
treme simplicity, and it is obvious that any
one capable of kindling a fire is qualified to
operate the device. 100
The water supply and exit pipes are to be
connected with the openings provided there-
for in the outer cylinder by means of screw-
threads, as is usually the case. Said supplyWc, 735,069,
