PROVISIONAL SPECIFICATION.
Improvements relating to Shower Baths.
I, HEINRICH SCHAFFSTAEDT, of 24 Bahnhofstrasse, Giessen, in the Empire of
Germany Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention relates to shower-baths in which the water is heated to the desired
temperature by means of a steam jet and comprises the improvements hereinafter
described.
•
The steam inlet pipe is connected through a cock with a pipe or pipes leading to
the base of the apparatus where it is in connection with a pipe attached to the base
by means of a stuffing box to allow the steam pipes to expand or contract under
different temperatures. The water inlet pipe opens into the lower end of a pipe
surrounding the steam pipes and of a sufficiently large diameter to allow the water
to pass between and round them. A cock connects the outer pipe with the pipe
carrying the rose. This latter pipe is fitted with a thermometer to show the
temperature of the water and with a cock to let out the water which remains in
the said pipe and to supply the bath itself with cold or warm water.
When the water cock is opened and the steam cock shut cold water will be
supplied but if the steam cock be opened the steam will pass through the steam
pipes downwards into the air and will heat the water flowing upwards round the
steam pipes.
If it is desired to use the condensed water from the steam instead of conducting
the steam into the open air it may be made to enter a condenser with which the water
supply pipe must in that case be brought communication.
By the use of an apparatus of this construction there is no danger of a person
being scalded as sometimes happens with existing apparatus if the steam should be
turned on too soon as in the present case the steam would be conducted away; the
condensed water which always has an objectionable odour does not mix with the water
supplying the bath; the temperature of the bathing water can be regulated instantly
to the desired degree; and the apparatus can be used with great advantage
wherever there is steam of any pressure and water of at least a pressure of
0.25 atmospheres.

COMPLETE SPECIFICATION.
Improvements relating to Shower Baths.
I, HEINRICH SCHAFFSTAEDT, of 24, Bahnhofstrasse, Giessen, in the Empire of
Germany, Manufacturer, 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:-
My invention relates to shower-baths in which the water is heated to the desired
temperature by means of a steam jet.
According to my invention I cause the steam for heating the water to pass
through one or several small pipes which are surrounded by water flowing in
the opposite direction which water is thereby heated to any desired temperature.

page_text: In order to enable my invention to be fully understood I will describe how it
can be carried into practice by reference to the accompanying drawing, in which
Figure 1 is a vertical section of an apparatus for heating the water supply to shower
baths and constructed according to my invention, and
Figure 2 is an elevation taken at a right angle to Figure 1.
The steam inlet pipe a is connected through a cock c with a pipe or pipes e leading
to the base of the apparatus where it is in connection with a pipe h attached to the
base by means of a stuffing box i to allow the steam pipes e to expand or contract
under different temperatures. The water inlet pipe b opens into the lower end of a
pipe surrounding the steam pipes e and of a sufficiently large diameter to allow the
water to pass between and round them. A cock d connects the outer pipe f with
the pipe o carrying the rose. This latter pipe is fitted with a thermometer T to show the
temperature of the water and with a cock g to let out the water which remains in
the pipe o and to supply the bath itself with cold or warm water.
When the water cock d is opened and the steam cock c is shut cold water will be
supplied by the cock g but if the steam cock c be opened the steam will pass through
the steam pipes e downwards into the air and will heat the water flowing upwards
round the steam pipes e. Each cock has a regulating index and scale to control the
water and steam inlets.
The shower bath is used in the following way, videlicet, the cock c must be first
opened to cause the steam to pass through the pipes e thereby heating the water
coming from the opposite direction. If now the cock d be opened and the cock g
remain closed warm water will ascend into the upper pipe o and flow from the
rose.
If the steam and water pressure be constant the temperature of the shower bath
water will be the same.
If it is desired to use the condensed water from the steam the pipe / instead of
conducting the steam into the open air may enter a condenser with which the water
supply pipe 6 must in that case be brought into communication.
It is obvious that instead of cocks I can employ valves.
By the use of an apparatus of this construction there is no danger of a person
being scalded, as sometimes happens with existing apparatus, if the steam should be
turned on too soon, as in the present case the steam would be conducted away; the
condensed water which always has an objectionable odour does not mix with the
water supplying the bath; the temperature of the bathing water can be regulated
instantly to the desired degree and the apparatus can be used with great advantage
wherever there is steam of any pressure and water of at least a pressure of
0-25 atmospheres.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) An apparatus for heating the water supplied to a shower bath in which the
steam for heating the water to any desired temperature is caused to pass through
one or several small pipes which are surrounded by the water flowing in an opposite
direction.
(2.) In apparatus for heating the water supplied to a shower bath the steam inlet
pipe a connected to the pipes e communicating with the pipe h fixed in the stuffing
box and in communication with the water inlet pipe b attached to the outer
pipe which communicates through the cock d with the upper pipe o to which is
fitted an outlet cock g and thermometer T substantially as set forth.
