COMPLETE SPECIFICATION.
An Improvement in or in connection with Shower Bath
Apparatus.
We, AUGUST AMANDUS OTTO Koor of 3 Kippingstrasse, Hamburg, Germany,
Architect, and JOHANNES FRIEDRICH KLENTZE of 6 Hirschgraben Hamburg,
Germany, Mechanician, 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 :-
Shower bath apparatus as at present constructed does not usually fully satisfy
the requirements of hygiene because generally it supplies cold water only, whereas
from a hygienic point of view a shower bath should be warm at first and then
gradually become colder.
In some cases this requirement is fulfilled by the provision of a complicated mixing
tap by means of which the shower bath apparatus can be connected to the bath boiler
or hot water supply.
This arrangement however is open to the objection that the entire contents of the
bath boiler must be heated to the desired temperature of about 30° C. to effect
which a relatively large quantity of fuel and considerable time are required. Now
this invention has for object to provide shower bath apparatus such that at first
warm water will be supplied and a few minutes afterwards, water of gradually
increasing coldness; this being effected with but a small consumption of fuel.
The improved apparatus is illustrated in the accompanying drawings in which
Fig. 1 is a side elevation of shower bath apparatus according to this invention,
Fig. 2 is an elevation taken at right angles to Fig. 1 ;
Fig. 3 shows the apparatus fitted in a bathroom and
Fig. 4 shows the apparatus arranged for bedroom use, the water being supplied
thereto by means of a flexible pipe connected to the water service, or it may be to
a water tank or cistern situated at a higher level.
The essential feature of this invention consists in the interposition in the pipe a
that supplies the exit rose b, of a vessel c, conveniently of about 5 to 10 litres
capacity, which can be heated by a suitable heating device, d, such as a spirit lamp,
gas flame, or the like.
The water in this vessel can be brought to the desired temperature of 30° C. in a
few minutes at a very small cost, so that even a poor person can procure in his own
dwelling a shower bath that shall fulfil all the requirements of hygiene.
As will be obvious when the usual valve is operated to allow water to escape
through the rose 6 the heated water will first escape from the vessel c followed
immediately by water that flows through the vessel c but is not heated to any
appreciable extent by the heating device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Providing in the supply pipe a of shower bath apparatus, a vessel c capable

page_text: of being heated, for the purpose of supplying to the exit rose b first warm water,
and then colder water substantially as described.
2. Shower bath apparatus constructed substantially as shewn in and described with
reference to the accompanying drawings.
