magnet.
Figure 6 is a perspective view of one of the heaters employed in the apparatus.
Figure 7 shews the manner in which the apparatus is applied to a bed.
The same letters of reference indicate the same parts in all the figures.
The apparatus consists of a box or case a of wood or other suitable material
lined with sheet iron or other equivalent material b and made preferably of fifty
centimetres in length by fifteen centimetres in breadth and fifteen centimetres in
depth internal measurement, to receive two bricks of the ordinary dimensions,
made of porous material so as to be capable of absorbing moisture and glazed on
five of their sides so as to prevent loss of heat. These bricks are placed in the
box a with their unglazed faces adjacent to the door d which is made of wire
gauze, perforated sheet-iron, or other equivalent material. The bricks may be
rendered porous in various ways, such as by mixing with the clay before moulding
combustible matters, such as wood sawdust for example, which becomes destroyed
on burning the bricks and leaves a number of small cells therein. To apply the
hot-air baths, the bricks are heated to a suitable degree and placed in the box a
wire gauze side d of which equalizes the temperature of the hot air emitted by the
apparatus.
To administer hot-air baths charged with steam or vapor of any suitable
infusion the box a is arranged as shewn in Figures 1 and 2 with the bricks laid
flat end to end and upon them is placed a container e made of tin-plate, filled with
water or other suitable liquid and provided at one side with openings F covered
with wire-gauze to allow of the escape of the vapors and with guards
g to prevent
the spilling of the liquid. The vapors as they are generated are carried off by the
hot air which becomes saturated therewith. With the above apparatus may be
combined an electric or magneto-electric apparatus h as shewn in Figures 1 and 2
or a magnet i as in Figures 3, 4, and 5. The apparatus would be placed in any
suitable position in the bed, according to the part of the body of the person
occupying the bed to which the treatment is to be applied whether for applying
dry hot air simply, or hot air moistened with steam or other vapors, and whether
combined or not with electrical or magnetic action as before described.
Figure 7 shews a perspective view of a bedstead upon which are applied three
bath-boxes a, one a¹ of which is provided with magneto-electric apparatus h and
another a with a magnet i, the boxes a a¹ being placed one on either side, and the

position, the bed clothes should be tucked in so as to prevent loss of heat.
The apparatus possesses the advantage, amongst others, of enabling hot-air
baths of high temperature, either dry or charged with vapors, to be administered
to patients while lying in bed in which the temperature may be gradually raised
above that of the surrounding atmosphere without any sudden variations, to the
desired degree, while evaporation is also easy and the atmosphere immediately
surrounding the patient is never saturated as is the case when the apparatus is
perfectly closed. The apparatus is moreover of simple construction and manage-
ment and can be readily shifted in position as required.
The form, dimensions, and details of arrangement, of the apparatus may be
varied as also the materials of which it is constructed, without in any way
changing the nature of the invention.

COMPLETE SPECIFICATION.
Improved Hot-air, Vapor, and Electro-therapeutic Bed-bath
Apparatus.
FRÉDÉRIC AUGUSTE DUBOIS DE DUNILAC, of 22 Rue de Château-Landon,
Paris, France, Gentleman, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement:-
This invention has for its object the application to persons when lying in bed
of hot air baths, either dry or charged with steam or other vapors in combination
or not with electric, magnetic or electro-magnetic treatment.
The invention is illustrated in the drawing accompanying the Provisional
Specification, in which
Figure 1 represents a front elevation, and
Figure 2 a cross section on line 1-2 of the apparatus combined with a magneto-
electric machine.
Figure 3 is a front elevation.
Figure 4 a cross section on line 3-4, and
Figure 5 a longitudinal section on line 5-6, of the apparatus combined with a
magnet.
Figure 6 is a perspective view of one of the heaters employed in the apparatus.
Figure 7 shews the manner in which the apparatus is applied to a bed.
The same letters of reference indicate the same parts in all figures.
The apparatus consists of a box or case a of wood or other suitable material
lined with sheet iron or other equivalent material b, and made preferably of fifty
centimetres in length by fifteen centimetres in breadth and fifteen centimetres in
depth, internal measurement, to receive two bricks c of the ordinary dimensions,
made of porous material, so as to be capable of absorbing moisture and glazed on
five of their sides so as to prevent loss of heat. These bricks are placed in the
box a with their unglazed faces adjacent to the door d which is made of wire
gauze, perforated sheet-iron, or other equivalent material. The bricks may be
rendered porous in various ways, such as by mixing with the clay before moulding
combustible matters, such as wood, sawdust for example, which becomes destroyed
on burning the bricks, and leaves a number of small cells therein. To apply the
hot air baths, the bricks are heated to a suitable degree and placed in the box a
the wire gauze side d of which equalizes the temperature of the hot-air emitted by
the apparatus.
To administer hot air baths charged with steam or vapor of any suitable infusion,

page_text: the box a is arranged, as shewn in Figures 1 & 2 with the bricks laid flat end to
end and upon them is placed a container e made of tin-plate filled with water or
other suitable liquid and provided at one side with openings fcovered with wire-
gauze to allow of the escape of the vapors and with guards g to prevent the spilling
of the liquids. The vapors as they are generated are carried off by the hot air
which becomes saturated therewith. With the above apparatus may be combined
an electric or magneto-electric apparatus h, as shewn in Figures 1 & 2, or a
magnet i, as in Figures 3, 4 & 5. The apparatus would be placed in any suitable
position in the bed, according to the part of the body of the person occupying the
bed to which the treatment is to be applied whether for applying dry hot air
simply, or hot air moistened with steam or other vapors, and whether combined or
not with electrical or magnetic action, as before described.
Figure 7 shows a perspective view of a bedstead upon which are applied three
bath-boxes a, one a¹ of which is provided with magneto-electric apparatus and
another a with a magnet i, the boxes a, a¹ being placed one on either side and the
box a' at the feet of the person lying on the bed. After placing the apparatus in
position the bed clothes should be tucked in so as to prevent loss of heat.
The apparatus possesses the advantages, amongst others, of enabling hot-air
baths, of high temperature, either dry or charged with vapors, to be administered
to patients while lying in bed, in which the temperature may be gradually raised
above that of the surrounding atmosphere without any sudden variations, to the
desired degree, while evaporation is also easy & the atmosphere immediately
surrounding the patient is never saturated as is the case when the apparatus is
perfectly closed. The apparatus is moreover of simple construction and manage-
ment and can be readily shifted in position as required.
The form, dimensions, and details of arrangement of the apparatus may be varied
as also the materials of which it is constructed without in any way changing the
nature of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1-The hereinbefore described box a containing a lining b, bricks c capable of
absorbing moisture, a perforated door d and a vessel e having perforations at f
and a guard g, substantially as described and illustrated in Figures 1 & 2.
2-The combination of the box and attachments set forth in Claim 1 with a
magneto-electric apparatus h, substantially as described and illustrated in
Fig. 1 & 2.
3
The combination of the box and attachment set forth in Claim 1 with a
magnet i, as described & illustrated in Fig. 5.
4-In an apparatus of the class described, the employment of bricks c capable of
absorbing moisture and glazed on five of their sides, substantially as described and
for the purpose set forth.
