Improvements in or relating to Baths.
I, CARL WALTER, of 2, Kurzestrasse, Berlin, in the Empire of Germany, Merchant,
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:-
―:
This invention has for its object an improved bath or bathing pan which may
be heated from below. Sitz baths in a recess of which cylinders containing
glowing charcoal are inserted for the purpose of heating the water, are already
known, but the object of the present invention has nothing to do with such
baths, as it relates to the use of an open furnace or fire for heating baths im-
materially of what kind they are, thus effecting a considerable reduction in the
cost of fuel and also of maintenance.
In the accompanying drawings:
Figure 1 is a plan view of a gas firing device;
Figure 2 an elevation and partial section of a portable bath provided with a
gas fire;
Figure 3 a section of a bath provided with a coal fire.
In Figures 1 and 2, the bath A stands on a portable support or carriage B.
Mounted in this carriage is a spirally coiled gas pipe C, which at its upper side
that is the one facing the bath, is flat, the said flat side being coated with asbestos
pulp D, for preventing the glowing hot pipes from coming in contact with the
floor of the bath. The ends of the bath are bent round and extend almost to
the bottom, and by this means the heat escaping underneath the bath is caught
and utilized so that the water is warmed by the hot air from the sides and ends.
In order to prevent too great a heating of the turned over part E, they are pro-
vided with an insertion filled with ash or other suitable material which commences
about the height of the level of the water. The hot air is carried off by means
of pipes e, shown in dotted lines.
The modification shown in Figure 3 consists in heating the bath by means of
a coal fire. The arrangement of the pan is the same as that hereinbefore described,
with the exception that a fire G is provided instead of a gas pipe C. This fire
consists of two compartments G1 G2 connected with one another and having a set
of rails. G is an open part on which a carriage travelling on the rails and pro-
vided with a grate and the like is arranged. In this carriage, the fire is kindled
and the flame first warms the bottom of the pan and then the gases pass over into
the hollow part E, so that the water is warmed at the ends and sides. As in the
first form of construction, the gases may be allowed to escape through a pipe e.
When the water has reached the desired temperature, the part G¹ is pushed along
the rails into the part, G2 which latter is connected with the chimney in any suitable
manner, so that the heat escapes to the outside. A part of it is formed with
asbestos walls from which the partition adjoining the open fire is removable,
and in order to allow of the fire passing into this compartment this partition
must be drawn out from the front. When the partition is again inserted the

page_text: fire is contained in an entirely closed box, the only opening to which is the pipe
leading to the chimney.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
1. A bath or bathing apparatus in which the water is heated by an open gas fire
arranged underneath it, the hot gases of which fire penetrate into a chamber formed
at the sides and ends of said bath whereby the warming of the water is effected
from said ends and sides, substantially as herein before described and shown in the
accompanying drawing.
2. A bath or bathing apparatus in which the water is heated by means of a
portable coal fire, which latter after the desired temperature of the water has been
obtained is run into an adjoining compartment from whence the heat may be
conveyed to the chimney, substantially as hereinbefore described and shown in
the accompanying drawings.
Dated this 9th day of August 1898.
