6 Claims.
(Cl. 257-254)
l.
The invention relates to water heaters and
particularly to utilizing a conventional range
boiler as a unit part of the heater or, in other
' words, associating the water heater and heating
medium employed with a boiler of the class de
scribed, and the object of the invention is to
provide a water heating unit employing a range
boiler with a heating coil associated with and
arranged beneath the boiler, with a source of
heat supply disposed immediately below the heat
er coil, whereby the products of combustion radi
ating from the heating medium may be directed
first onto the coil and then upon the boiler; a
further object being to provide a water heating
member or coil comprising a series of tubes open
at one end, each tube containing a baffle or par
tition plate forming circulating passages within
- rthe tubes and detachable plugs at the open ends
of the tubes, facilitating the removal of the
plates and the cleaning of the tubes and plates
whenever desired; and with these and other ob
-jects in View, the invention consists in a heater
unit of the class and for the purpose specified,
which is simple in construction, eilîcient in use,
and which is constructed as hereinafter described
and claimed.
The invention is fully disclosed in the following
specification, of which the accompanying draw
ing forms a part, in which the separate parts
.of my improvement are designated by suitable
reference characters in each of the views, and
»in which:
Fig. 1 is a side and sectional view of the unit
made according to my invention with part of the
.35 construction broken away.
Fig. 2 is a partial section on the line 2-2 of
Fig. 1.
Fig. 3 is a partial section on the line 3-3 of
Fig. k2.
`
Fig. 4 is a detail plan and sectional view of a
modified form of heater which I may employ,
and,
'
Fig. 45 is a perspective view of one of the baille
plates which I employ.
`In Fig. 1 of the drawing, I have indicated at
I0 yairange boiler or hot water tank of more or
less conventional form supported on a stand II
provided at its upper end with a flanged ring I2
upon which the boiler or tank seats. The water
supply and discharge tubes to the tank or boiler
are not shown but these will be of the conven
tional or any desired arrangement. But, at I3 I
yhave shown the usual drain pipe extending from
` the bottom wall of the boiler, which pipe is pro
vided with a usual Valve or shut-off, not shown.
.
At I4, I have shown the cold water circulating
pipe extending from the lower portion of the
boiler I0, and connected, asi indicated at I5,
with my improved water heater I6, a union Illa
being incorporated in the pipe I4 to facilitate the 55
mounting of the water heater as will be apparent.
The water is discharged from the heater I5
through a pipe I'I which couples with a fourway
coupling I3 with which the hot Water supply pipe
I9 is also coupled, the latter extending to and lo
being connected with the upper end of the boiler
as indicated at 20. Clean out plugs I8a are pro
vided on the coupling I8 to facilitate cleaning
out the pipes I'I and I9.
In the construction shown I employ a skirt or
jacket portion 2 I which extends downwardly from
the ring I2 and envelops the stand II, water
heater I6, as well as the gas burner 22, or other
heating medium or source of heat supply. In
other words, `the skirt or jacket 2E forms what
might be termed a heater casing which is posi
tioned directly below the boiler I9. The burner
22 is supported on transverse straps 23 and the
rear end of the water heater I6 is supported on
a transverse strap or rod 24, the forward end,A
being supported by the pipes I4 and I9 and the y
connections thereof. At the lower portion of
the skirt 2l are a number of air inlet openings
25 for supply to the burner 22. At one side of
the skirt or casing adjacent the lower end of Í
the boiler is an elbow exhaust 26 for the dis
charge of products of combustion from the cham
ber 2 la within the skirt 2l.
The water heater I6 as shown in Figs. 1 to 3 in
clusive consists of a casing 2l having one longi- ¿2.
tudinal passage 2S extending therethrough, and
three transverse passages 29, 36, and 3|, the for
ward ends of which are cloœd by plugs 29a, 39a,
and Sla, and coupled with the rear ends thereof
are elongated thimble shaped tubes 32, 33, ande'
34.
In each of these tubes are arranged baille
or partition walls 35, 35, and 3l', the forward end
portions of which are provided with laterally ex
tending ears 38 which set in slots 39 formed in
the casing 2'! at the inner end of the plugs 29a,
39a, and 3Ia, so as to position the baffle plates 35,
36, and 3l in the diagonal arrangement illus
trated clearly in Fig. 3 of the drawing to provide
at the lower side of the circulating tubes 32, 33,
and 34, passages 40 and at the upper portions
thereof, passages 4I placed in connection at the
rear closed .ends of the tubes 32, 33, and 34 as in
dicated at 42, the latter being formed by project
ing stop pins or fingers ¿I3 at the inner ends of
the plates 35, 3E, and 3l. In Fig. 5 of the drawing

of supply and still further may be used for com
mercial purposes. But, in all cases the funda
,
In other words, in the construction shown in
Figs. 1 to 3 inclusive the heater I6 is made up into
three tubes, each subdivided by a baii‘le or parti
tion plate to divide the same into what may be
termed intake passages 4Q and exhaust passages
4I placed in communication at the inner ends of
10 the tube as at 42 so that cold water entering
mental plan of the unit will be carried out.
Having fully described my invention, what I
claim as new and desire to secure by Letters Pat
ent, is:
l. A heat exchanger device comprising a casing
having a continuous bore extending longitudinally 10
through the pipe I5 will ñrst pass into the bore
therethrough, a plurality of tubes radiating from
28 below the plate 35, ño-w backwardly through
said bore at spaced intervals longitudinally there
of, the chambers of said tubes opening into and
the passage 40 and then forwardly through the
passage 4I in the tube 32, again into the bore 28
15 beneath the plate 35, pass successively through
the tubes 33 and 34 in the same manner, and
being in communication through said bore, means
arranged longitudinally of said tubes and ex
tending through said bore for subdividing the
ñnally discharge through the pipe I'I from which
tubes into independent circulating passages placed
it will pass into the pipe I9 and thus into the
boiler III. In other words, the circulation be
20 comes continuous when the burner 22 is in op
eration to circulate water'from the bottom of the
boiler back and forth through the tubes of the
heater I6 and to the tube of the boiler. From
in communication with each other at the free end
of the tubes said last named means comprising
plates, and the casing having spaced passages in ~
alinement with said tubes and communicating
with the bore of said casing to provide attachment
time to time, and especially in using heater units
25 o-f this type with certain types of water supplies,
tubes.
ing having a continuous bore extending longi
_in the pipes, tubes, and the like of the heater
unit and the circulating pipes of the system. For
this reason, the plugs 29a, 38a, and 3io: are em
tudinally therethrough, a plurality of tubes ra
and 31 to clean off said plates as well as the
40
45
50
tubes 32, 33, and 34. The plugs [email protected] may also be
removed to clean out the longitudinal passage
or bore 28, the pipe I'l and the pipe I9, thus keep
ing the circulating system absolutely clean at all
times and in like manner maintaining the most
eñ‘icient heating exchange between the burner 22
or other heating mediums employed and the
Walls of the tubes of the burner.
It will be understood that instead of arranging
the member I6 in a straight horizontal plane as
indicated in Fig. 1 the same may be disposed in
an inclined plane with the end attached to the
pipe I1 higher than the end attached at the pipe
I5 to increase circulation.
In Fig. 4 of the drawing I have shown a slight
modification of the structure shown in Figs. 1 to 3
inclusive wherein the water heater |611 has its
4tubes 32a, 33a, and 34a., cast or otherwise formed
integral with the casing 21a and aside from this
structural change the heater IGa is the same as
‘the heater I6 and operates in the same manner.
It will also be seen upon consideration of Fig. 2
'of the drawing that a cover 44 may be formed
55 on the casing or skirt 2| in alinement with the
plugs 29a, 39a, and 3Ia to give access thereto
Vwhenever desired, the cover being hinged as is
indicated at 45.

comprising plates, the casing having spaced pas
sages in alinement with said tubes and communi
cating with the bore of said casing to provide
attachment and detachment of the plates with
respect to said tubes, plugs detachable from the 40
casing -for closing each of said passages, and
means on the plates and in said casing for keying
the plates against rotation in the casing and said
tubes.

tending through said bore for subdividing the
tubes into independent circulating passages placedin communication with each other at the free end
of the tubes, said last named means comprising
plates, the casing having spaced passages in
alinement with said tubes and communicating
with the bore of said casing to provide attach
ment and detachment of the plates with respect
to said tubes, plugs detachable from the casing 60
the manner described a very simple as well as
for closing each of said paœages, and means on

stood that the products of combustion rising
above the heater IG-Ißa and circulating around
the plates and in said casing for keying the plates
against rotation in the casing and said tubes, the
said plates being arranged in each tube in an
upwardly inclined direction with respect to the
longitudinal plane of the bore in said casing.
65 the tubes thereof are directed upon the bottom
of the boiler and serve to partially heat the water
in the bottom of the boiler and to this degree
' render the heater unit more efficient.
It will be understood that my invention is not
necessarily limited to the specific arrangement
of parts herein shown and described nor to the
`number of circulating tubes employed in the
