A New and Improved Hot Air Bath or Appliance.
I, ARTHUR EDWIN GREVILLE, of 2, Staple Inn, Holborn, in the County of
London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to hot air baths and has for its object to provide a hot
air bath for local application to any limited portion of the body.
The invention consists of an appliance in which a resistance wire is employed
which is heated or rendered incandescent by the passage there-through of an
electric current, such resistance wire being applied in close proximity to the
portion of the body to be treated with the bath, a sheet of gauze or perforated
metal or material being interposed between the resistance wire and the surface
of the body, while a protected exterior rim or flange is provided which may contact
with the body, so that, thereby, the gauze or perforated plate shall be removed
from contact with the skin, but shall permit the heat rays to be directed against
the surface or part of the body to be treated. Such an apparatus is made of a
form to correspond with the shape of that part of the body to be treated, separate
apparatus, for instance, being used for treatment of the stomach, throat, ear,
spine, knee, elbow, hip, shoulder and other parts, while one or more such apparatus
may be used to encircle any part or limb of the body when so required.
In carrying the invention into effect when providing a hot air bath or appliance
for application to the stomach a plate of metal or other suitable material is
employed having a slightly concave curvature and of oval shape and dimensions
convenient for the use of the bath or appliance upon that part of the body. Upon
this plate are provided opposing series of insulators which are affixed to a support-
ing frame between which and the plate a strip of asbestos may be interposed. A
resistance wire is stretched in series about and between the insulators and its
extremities are secured within terminals to which an external circuit of storage
batteries or other suitable source of electric current is connected.
The plate upon
which the insulators are mounted is hinged to a cover so connected that the cover
may be connected by hingeing pins upon either side and may be disconnected
from either or both sides. The cover is provided with an outer wall or flange
which carries perforated gauze or a perforated metallic or other plate with a
curvature corresponding to that of the insulator carrying plate, such wall or flange
projecting beyond the surface of the gauze or perforated plate and having provided
thereupon quilted satin or velvet for contact with the skin, so that the gauze or
perforated plate shall be maintained out of contact with the skin.
It will be understood that on the electric current being passed through, the

page_text: resistance wires become immediately heated and the heat is radiated through to the
surface upon which the appliance is placed.
An applicance substantially the same as that hereinbefore described but of
smaller dimensions and different shape may be employed for the treatment of the
ear, or throat, or other part of the body, but it is obvious for instance, that in the 5
treatment of the throat two or more such appliances may be used to completely
encircle the throat or one alone may be employed which may be constituted of two
parts, or hinged to the other, so as to be conveniently applied for encircling that
part of the body.
An apparatus for the treatment of the spine may be provided of a series of 1
suitably shaped appliances such as that herein before described arranged side by
side and working in parallel or joined together or encased in a coat or cover upon
which the patient may lie.

I, ARTHUR EDWIN GREVILLE, of 2, Staple Inn, Holborn, in the County of
London, Gentleman, 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 hot air baths and has for its object to provide a hot
air bath for local application to any limited portion of the body.
The invention consists of an appliance in which a resistance wire is employed
which is heated or rendered incandescent by the passage therethrough of an
electric current, such resistance wire being applied in close proximity to the
portion of the body to be treated with the bath, a sheet of gauze or perforated
metal or material being interposed between the resistance wire and the surface
of the body, while a protected exterior rim or flange is provided which may contact
with the body, so that, thereby, the gauze or perforated plate shall be removed
from contact with the skin, but shall permit the heat rays to be directed against
the surface or part of the body to be treated. Such an apparatus is made of a form
to correspond with the shape of that part of the body to be treated, separate
apparatus, for instance, being used for treatment of the stomach, throat, ear, spine,
knee, elbow, hip, shoulder and other parts, while one or more such apparatus may
be used to encircle any part or limb of the body when so required.
The invention is illustrated in the accompanying drawings, in which,
Figures 1, 2 and 3 are respectively front elevation, plan and side sectional
elevation of an appliance for application to the stomach, and,
Figure 4 is a back view of the same showing the back plate open.
Figures 5 and 6 are elevations of an appliance for application to the throat,
and,
Figure 7 is a back view of the same with the back plate removed.
Figures 8 and 9 are respectively elevation and plan of an appliance for
application to the ear.

page_text: Figure 10 is a front elevation of an appliance for application to the back and
spine, and,
Figure 11. is a perspective view thereof showing the plates opened.
In carrying the invention into effect as illustrated in Figures 1 to 4 when
providing a hot air bath or appliance for application to the stomach a plate A
of metal or other suitable material is employed having a slightly concave
curvature and of oval shape and dimensions convenient for the use of the bath
or appliance upon that part of the body. Upon this plate are provided opposing
series of insulators B which are affixed to a supporting frame C between which and
the plate a strip of asbestos D may be interposed. A resistance wire E is stretched
in series about and between the insulators and its extremities are secured within
terminals to which an external circuit of storage batteries or other suitable
source of electric current is connected. The plate upon which the insulators are
mounted is hinged to a cover G so connected that the cover may be connected by
hingeing pins upon either side and may be disconnected from either or both sides.
The cover is provided with an outer wall or flange H which carries perforated gauze
or a perforated metallic or other plate I with a curvature corresponding to that of
the insulator carrying plate A, such wall or flange H projecting beyond the surface
of the gauze or perforated plate I and having provided thereupon quilted satin
or velvet for contact with the skin, so that the gauze or perforated plate shall be
maintained out of contact with the skin.
It will be understood that on the electric current being passed through, the
resistance wires D become immediately heated and the heat is radiated through to
the surface upon which the appliance is placed.
An appliance substantially the same as that herein before described but of smaller
dimensions and different shape may be employed for the treatment of the throat
as illustrated in Figures 5 to 7, or of the car as illustrated in Figures 8 and 9,
or other part of the body, but it is obvious, for instance, that in the treatment of
the throat two or more such appliances may be used to completely encircle the
throat or one alone may be employed which may be constituted of two parts, one
hinged to the other, so as to be conveniently applied for encircling that part of
the body.
In the appliance illustrated in Figures 5, 6 and 7 the insulators B instead of
being attached to the back plate A are arranged upon curved supporting rods J
otherwise the construction is similar to that of the appliance illustrated in
Figures 1 to 4.
An apparatus for treatment of the spine may be provided as illustrated in
Figures 10 and 11 which consists of two suitably shaped appliances K, L, such as
that hereinbefore described with reference to Figures 1 to 4 arranged side by side
and working in parallel and joined together. They may be encased in a coat or
cover upon which the patient may lie.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A hot air bath or appliance for local application of heat to the human body,
consisting of a cover or receptacle in which electric resistance wires or coils are
provided and a protective shield, the edges of the cover being caused to lie in close
contact with the part of the body to be treated substantially as herein before
described.
2. A hot air bath or appliance for local application of heat to the human body
constructed and provided substantially as herein before described with reference to
Figures 1 to 4 of the accompanying drawings.
3. A hot air bath or appliance for local application of heat to the human body
constructed and provided substantially as herein before described with reference to
Figures 5 to 7 of the accompanying drawings.
4. A hot air bath or appliance for local application of heat to the human body

page_text: constructed and provided substantially as hereinbefore described with reference to
Figures 8 and 9 of the accompanying drawings.
5. A hot air bath or appliance for local application of heat to the human body
constructed and provided substantially as herein before described with reference to
Figures 10 and 11 of the accompanying drawings.
