such an apparatus wherein the heater is placed
40 in position for greatest efliciency of heating by
natural convection, wherein the least danger of
injury to the user is encountered and wherein the

water pan is accomplished.
It is a further object of this invention to pro

The framework joining the walls I, 2, 3, 4 and
top wall member 5, and providing a support for
the door 6 and top wall member 8, is preferably
formed of wood and the walls may be formed of
any suitable material such as plywood, which
may or may not be provided on its inside sur
faces with insulation, or the walls may, if de
sired, be formed of insulating wall board. The
inclination, from the vertical, of the hinges H
which connect the door e pivotally to the frame
work, makes it unnecessary to use any latching
means on the door, as the door will be retained,
by its own weight, in closed position, when it is
placed in such position. A handle l2'is provided 45
at the side of the door opposite the hinges H to
permit of the opening and closing of the door by
the user.

surface of the forwardly and upwardly inclined
bottom wall 4 provides a foot rest for the user
who sits upon the seat It with his feet resting
on the inner surface of the wall 4, with his neck
projecting through the aperture formed by the
complementary notches 9 and Ill and with the
back of his head supported by the head rest IS.
The semi-recumbent position afforded by this
disposition of the head rest [5, the seat I8 and
20 the foot rest de?ned by the wall 4 is such as to
provide utmost ease and encourage complete re
laxation and repose. The provision of the sub
stantial skeleton frame of pentagonal section
provides the utmost strength possible for the
weight of the cabinet construction. The great
number of angles provided by this pentagonal
construction increases the rigidity of the struc
ture.
The inclination of the wall 4 forwardly
and upwardly with respect to the horizontal
30 makes it possible to utilize the inner surface of
the wall 4 as a foot rest and to avoid the further
addition of weight to the cabinet by attachment
thereto of a separate foot rest.
As shown in Figure 2, the portion ‘of the frame
work to which the hinges I l are attached provides
a support for the door 6 when it is open. In this
position, the door may be easily grasped by a user
seated on the seat of the bath, with his feet rest
ing upon the inner surface of the wall 4, and his
40 neck disposed in the notch 10 of the top wall
member 5. The user may then close the door and
it will, or" its own weight, remain closed until it
is pushed open from the inside by the user. This
provides means whereby a user may, at any time,
45 relieve himself from excessive heat within the
cabinet.
As shown in Figure 2, an aperture 6a may be
provided in the door 6 which may be opened from
the inside to reduce the temperature within the
bath cabinet. Any suitable means, such as a
slidable or hinged door, may be provided for vary
ing the effective size of the aperture 6d. Se
cured to the inside surface of the base wall 2 is
a water pan 2!) which is provided with upwardly
directed front and side ?anges and a substan—
tially elongated inclined rear wall 2|, which has
its upper end portion secured to the rear wall 3
and which is adapted to serve as a re?ector for
directing upwardly heat generated by a heater,
generally designated 22, which is mounted with
in the water pan 28 and suitably insulated there
from. This heater is provided with suitable re
sistance coils and electric energy is fed thereto
by conduits 23 and 24 which are connected to a
suitable, adjustable thermostat, generally desig
apparatus, remains at the constant desired value.
base 26, whereby to complete the electrical cir
cuit through the thermostat to the heater 22.
After the elapse of a few minutes, the tempera
ture within the bath cabinet will reach and re
main at the desired predetermined value, and
the user may then open the door 6 and sit upon
the seat l8 with his neck disposed within the
notch 9 and his feet supported on the inner side
of the wall 4 and then close the door 6, after
placing a towel about his neck in order to avoid
the escape of heat and/or moist air between his
neck and the aperture provided by the comple
mentary notches 9 and I0. After the tempera
ture within the cabinet has reached the prede
termined value, the thermostat 25 will act auto
matically to retain the temperature at the prede
termined constant.
It will thus be seen that the illustrated struc
ture provides an electrothermo bath of simple
operation, of extremely light weight and port
ability, wherein the user is supported in a com
fortable, restful, recumbent position, and that,
due to the simplicity of the construction of the 30
interior and the avoidance of encumbrance of
the interior surfaces of the cabinet, the utmost
ease of cleaning is achieved.
It will furthermore be seen that, by utilizing a I
construction wherein the door is automatically
retained in closed position, without the use of
latching means, the user is continually enabled to
leave the bath at any time. Likewise, he is able
to reduce the heat momentarily by opening the
aperture 6a or partially opening the door 6. It
will furthermore be seen that the disposition of
the heater is such that the feet of the user, when
he is leaving the machine, will not contact the
heater. It will furthermore be seen that the
disposition of the heater is such that the utmost 45
efficiency of vaporization of water in the water
pan will be achieved and the ultimate circulation
of heat under the force of natural convection will
be achieved. Furthermore, the reflector 21 will
aid in the direction of heat to the body of the
user.
It will further be noted that the back rest con
struction is such as to comfortably support the
back of the user without preventing heat from
reaching the user’s back.
It will be understood that the above described
structure is merely illustrative of one manner
in which the principles of my invention may be
utilized and that I desire to comprehend within
my invention such modi?cations as come within 60
the scope of the claims and the invention.
