page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex 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 relates to portable steam or Turkish bath apparatus.
The apparatus can be heated by a gas, petroleum, or preferably a spirit lamp.
and can be applied in any chamber. For the purpose of taking a bath, a closed
box is necessary or a covering surrounding the body of the bather.
In the accompanying drawing.
Figure 1 is a vertical central section.
Figure 2 a horizontal section on the line A, B, Figure 1.
Figure 3 a vertical section on line C, D Figure 1, and
Figure 4 a plan of the said apparatus.
a is a metal boiler with an internal heating apparatus b, c, d, preferably of the
form shewn, on account of the large heating surface thereby obtained.
The heat of the lamp, which is placed underneath the boiler in the heating
chamber e, impinges on the bottom of the boiler, distributes itself through the
tubes c, and converging in the chamber d, escapes through the flue or chimney.
g is a nozzle through which the steam generated in the boiler is discharged into
the tubes h and k for the purpose of supplying the bath.
The tube h in which the nozzle g is situated, intersects on the one hand, the side
of the boiler with a sufficient projection to allow the tube k, preferably of the
form shewn, to be attached, and, on the other hand the flue or chimney f with an
outward prolongation. This tube is provided with two openings, one of which
is placed outside, the other m inside, the.chimney.
n is a tube fitting into the tube h also provided with two openings o and p
corresponding with the two openings l. m. g is a tube with a movable cover r by
which the quantity of water in the boiler is determined and controlled. The tube 8
whose funnel-shaped top t is connected with a reservoir above the cover of
the boiler serves as a safety valve against overheating of the water as it allows
the same to spread itself over the surface of the reservoir, and when cooled
down, to return to the boiler. The funnel serves also for filling and emptying the
apparatus.

page_text: x, x are handles for taking hold of the apparatus; y a handle for regulating the
tube or valve n.
The method of employment is as follows:-viz;-The boiler a is filled with
water to the height of the tube q, and the cover r fastened down. The valve
tube n is so set, that the opening m is closed and the openings and o are open.
The lamp is then placed in the heating chamber e and lighted.
As soon as the water boils and steam begins to escape through the nozzle g, air
will be sucked in through the openings an o by the force of the jet and having
been warmed by contact with the sides of the tube h, will be injected together
with the steam jet, which supplies the steam or Turkish bath, into the said closed
box or covering.
To obtain a greater heat, the valve tube n is turned by means of the handle y,
whereby the opening l is partly closed, and the opening m correspondingly opened,
and instead of heated air a mixture of heated air and superfluous heat from the
products of combustion will be simultaneously injected together with the steam
from the steam jet into the bath.
By entirely closing the opening and thereby entirely opening m, the superfluous
heat of the products of combustion will be entirely injected, together with the
steam from the steam jet, into the bath.
The advantages of this apparatus are that it can be used at any moment in any
chamber; that it can be taken on a journey with the necessary cover and folding
frame and that within a few minutes after arrival it can be set in operation and
supply a steam, or Turkish bath with an adjustable temperature in one's own room.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign Correspondent I declare that what I claim is
First. A portable steam, or Turkish bath, consisting of a metal boiler which is
heated by a gas, petroleum, or preferably a spirit lamp, and whose steam outlet is
connected in such manner with an apparatus for heating the air, that the heated
air can by means of the steam jet, be injected together with the steam into
the bath.
Second. A portable steam or Turkish bath consisting of a metal boiler which is
heated by a gas, petroleum, or preferably a spirit lamp and whose steam outlet is
connected in such a manner with the chimney of the heating apparatus that the
superfluous heat of the products of combustion, which otherwise escape through
the chimney, can by means of the steam jet, be injected together with the steam
into the bath.
Third. A portable steam, or Turkish bath consisting of a metal boiler which is
heated by a gas, petroleum, or preferably a spirit lamp, and whose steam outlet is
connected in such a manner with an apparatus for heating the air and, with the
chimney of the heating apparatus that the heated air and the superfluous heat of
the products of combustion can, by means of the steam jet be injected (in
quantities corresponding with the position of a valve) together with the steam into
the bath.
Fourth. The combination of the metal boiler a, steam nozzle g, hot air tube h
and chimney f substantially as, and for the purpose, set-forth.
