WATER HEATER
Clyde L. Chacey, Leavenworth, Kans.
Application May 17, 1937, Serial No. 143,159
1 Claim.
(Cl. 219—38)
The invention relates to a water heater and
more especially to a portable electric water heater
for stock watering tanks.
The primary object of the invention is the pro
5 vision of a heater of this character, wherein the
body of the same is jacketed in a manner for the
circulation of water entirely about the electric
heating units held within the body, the heater
being adapted to be placed within a watering tank
for stock and in this manner the water within
the tank can be heated during cold weather.
Another object of the invention is the provi
sion of a heater of this character, wherein the
construction of the same is novel in form and
15 can be readily placed within a watering tank
for the heating of the water therein.
A further object of the invention is the pro
vision of a heater of this character, which is sim
ple in its construction, thoroughly reliable and ef
20 ?cient in operation, light in weight for rendering
the same portable, yet strong, durable and inex
pensive to manufacture.
With these and other objects in view, the in
vention consists in the features of construction,
combination and arrangement of parts as will
be hereinafter more fully described, illustrated in
the accompanying drawing, which discloses the
preferred embodiment of the invention and point
ed out in the claim hereunto appended.
In the accompanying drawing:
Figure l is a fragmentary vertical sectional
View through a water tank for stock showing the
heater constructed in accordance with the in
vention therein.
Figure 2 is a top plan view partly in section.
Figure 3 is a vertical longitudinal sectional view
through the heater.
Figure 4 is a vertical transverse sectional view
thereof.

Similar reference characters indicate corre
sponding parts throughout the several views in
the drawing.
Referring to the drawing in detail, A desig
nates generally a portion of a water tank for the
5 watering of stock and is of any conventional form
while B denotes generally the electric water heat
er constituting the present invention and herein
after fully described.
The electric water heater B comprises a cas
0 ing or housing [0 preferably of rectangular shape
although it may be otherwise formed and includes
a bottom ll, side and end walls l2 and I3, re—
spectively, and a removable hollow head l4 which
is separably bolted at I5 in place.
Formed centrally in the casing or housing [0
and opening through its bottom II and into the
hollow head I4 is a water circulating tube I6
while at the sides l2 and ends I3 of the casing
or housing Ill are water circulating spaces 11,
these opening through the bottom H and into
the hollow head I4.
Interiorly of the casing or housing It and en 5
tirely about the tube It is an electric heating
element including a plurality of resistance coils
or heating units l8 which are in parallel in elec
tric source of supply, the current wires of this
source of supply being indicated at I9 and 20, 10
respectively, and are preferably con?ned within
a ?exible conduit or pipe 2! suitably ?tted with
the casing or housing Ill.
The chamber 22 for the electric heating ele
ment including the units l8 has arranged therein 15
an insulating lining 23 while the head M is bolted,
there being a gasket 24 arranged between this
head and the said housing or casing to avoid
leakage of water at this point.
The head [4 at opposite ends is provided with
holes or openings 22 so that water will discharge
therefrom during the circulation of such water
through the tube It, spaces I1 and head it in the
working of the heater. At the bottom H of the
casing or housing ID are legs or feet 26 which ele
vate the said housing or casing the proper height
when at rest upon the bottom of the tank A on
the placing of the heater therein. These legs or
feet 26 are preferably located at the lower four
corners of the casing or housing Ill.
When the heater is placed within the tank A
and the latter contains water, the circulation of
the same during the heating period will be had
through the tube it, spaces ill and head id as
is indicated by the arrows in Figures 1 to 4 of
the drawing. In this manner the Water within
the tank A will become heated during the use
of the tank in cold weather for the watering of
stock.
In lieu of the ?exible conduit 2i a rigid pipe
may be employed,
What is claimed is:
An electric water heater comprising a casing
having a bottom, side and end walls, respectively,
a removable hollow head topping said casing, 45
said casing having spaces inwardly of and next
to the sides and ends thereof and opening into the
hollow head and also through the bottom of the
casing, a tubular column formed with the said
casing and opening through the bottom thereof 50
and into the hollow head, and an electric heat
ing element including a plurality of resistance
coils disposed concentrically about the said col
umn interiorly of the casing between the bot
55
tom and the said head.
