PROVISIONAL SPECIFICATION.
Improvements relating to Shower-baths, Douches, and the like.
I, MAX BIERMANN, of Gera, in the Empire of Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to arrange the supply of water to a shower,
douche, spray or the like in a bath or bathing establishment or otherwise, that the
water delivered therefrom when set in action may commence with hot water of a
desired degree of temperature and thenceforth gradually become colder and colder
without requiring any special manipulations to gradually cool the fall, shower,
douche, spray or other delivery of water.
A suitable vessel is employed having an inlet for hot water or else gas or other
burners or means for heating the water therein, and in this vessel is a rotary
mixer preferably in the form of a vertically supported revolvable cone or an
inverted cone in connection with a pallet wheel near which is a cold water inlet or
inlets so arranged that when the cold water is turned on it enters and revolves the
pallet wheel and with it the conc, or cones if more than one. An outlet pipe is
carried to the shower rose, douche, spray, needle spray, or other device from which
it is to be delivered.
The vessel is intended to be filled with hot water at the desired temperature, or
with water which is then heated to the desired temperature. When the shower or
the like is required, cold water is turned on and on entering forces out so much hot
water while it is gradually mixed with the volume of water remaining, so that the
water delivered will gradually run colder and colder until the hot water is gradually
all removed and only cold water will run through the apparatus.
In place of a cone or cones and pallet wheel for mixing the water, a reaction
wheel may be used, that is, a rotary set of bent tubes radiating from a hub and
made to revolve by the reactive force of the incoming cold water which enters at
the hub and issues at jets along the tubes or at the ends of the tubes.

COMPLETE SPECIFICATION.
Improvements relating to Shower-baths, Douches, and the like.
I MAX BIERMANN of Gera 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:―
The object of this invention is to arrange the supply of water to a shower,
douche, spray or the like in a bath or bathing establishment or otherwise, that the
water delivered therefrom, when set in action, may commence with hot water of a
desired degree of temperature and thenceforth gradually become colder and colder
without requiring any special manipulations to gradually cool the fall, shower,
douche, spray or other delivery of water.
A suitable vessel is employed having an inlet for hot water or else gas or other
burners or means for heating the water therein, and in this vessel is a rotary mixer
preferably in the form of a vertically supported revolvable cone or an inverted
cone in connection with a pallet wheel near which is a cold water inlet or inlets so
arranged that when the cold water is turned on it enters and revolves the pallet
ID 437

page_text: wheel and with it the cone, or cones if more than one.
An outlet pipe is carried to
the shower rose, douche, spray, needle spray, or other device from which it is to be
delivered.
The vessel is intended to be filled with hot water at the desired temperature or
with water which is then heated to the desired temperature. When the shower or
the like is required, cold water is turned on and on entering forces out so much
hot water while it is gradually mixed with the volume of water remaining so that
the water delivered will gradually run colder and colder until the hot water is
gradually all removed and only cold water will run through the apparatus.
In place of a cone or cones and pallet wheel for mixing the water, a reaction
wheel may be used, that is, a rotary set of bent tubes radiating from a hub and
made to revolve by the reactive force of the incoming cold water which enters at
the hub and issues at the jets along the tubes or at the ends of the tubes.
This invention is illustrated in Figs. 1 to 9 of the annexed drawings.
Fig. 1 shows a shower bath or douche etc. with heating apparatus in vertical
section.
Fig. 2 shows the water reservoir or vessel in cross section on the line RR
of Fig. 1.
Fig. 3 cross section through the mixing cone and parts on line S S, Fig. 1.
Fig. 4 shows a vessel with more than one mixing cone.
Fig. 5 is a plan of the vessel with two water supply pipes.
Fig. 6 shows a vessel with inverted cone in clevational section.
Fig. 7 is a plan of Fig. 6.
Fig. 8 shows a vessel with a reaction wheel, Fig. 9 being a plan view of Fig. 8.
A is a vessel intended to receive water either heated by a special heating con-
trivance or stove B.(Fig. 1), by gas, charcoal or other fuel therein, or after heating
in another boiler whence it is supplied by pipe C. (Fig. 4).
In the interior of the vessel A is the rotary mixing cone K with the pallet
wheel to be set in rotation by one (Fig. 3) or more (Figs. 5 to 7) water jets
from substantially tangential nozzles a a. The mixing cone tapers upwardly and
on its circumference it is provided with ribs and entrance slits 6¹.
By the revolving motion of the mixing cone K and with assistance of the ribs c
provided on the inner wall of the vessel A a very intimate mixing of the heated
water contained in the receptacle is effected with the entering cold water.
By arrangement of a thermometer the original temperature can be read as well
as its gradual fall during the supply of cold water.
Where the vessel is to serve at the same time for feeding more than one shower
bath, douche, etc. it is preferabic to use more than one mixing cone K arranged one
above another as shown in Fig. 4 of the drawing.
Likewise also (Fig. 6) the arrangement of the other parts remaining the same,
the cone or cones K may be inverted so that the apex of each is next to the pallet
wheel and the base of the cone is upwardly directed. The functions of the cones K
and the pallet wheel k may also be united in one piece where a reaction wheel D
(Figs. 8 and 9) with suitably bent radiating pipes is employed.
The shower, douche, etc. may be connected in various ways with the mixer
described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is.
1. In a shower bath, douche, or like delivery of water, an apparatus for delivering
water of gradually decreasing temperature, comprising a vessel A adapted to
receive hot water or water to be heated therein and containing one or more mixing
cones put in rotary motion by entrance of tangential jets of cold water, which
is thus mixed with the contents of the vessel, and expel therefrom a stream of
water of gradually decreasing temperature substantially as set forth.

page_text: 2. In the mixing device described in Claim 1 the arrangement of inverted cone
or cones K with pallet wheels below (see Figs. 6 and 7) substantially as set
forth.
3. In the mixing device described in Claim 1, the replacement of the cones and
pallet wheels by a rotary reaction wheel, consisting of a rotary system of radiating
pipes, bent or otherwise, and provided with any suitable number of holes for the
outlet of the cold water supplied through said pipes.
