of Dublin, Ireland, M.D., for the Invention of "A NEW MODE OF
APPARATUS FOR BREATHING WARM AIR."
AND
Sealed the 16th March 1877, and dated the 20th September 1876.
PROVISIONAL SPECIFICATION left by the said Noble Seward at the Office
of the Commissioners of Patents on the 20th September 1876.
NOBLE SEWARD, of Riversdale, Templeogue, in the County of Dublin, Ireland,
M.D. "A NEW MODE OF AND APPARATUS FOR BREATHING WARM AIR."
The object of this Invention is to enable a person at any time and in any place
of breathing air at any temperature which may be considered necessary by an
apparatus attached to and worn on the body.
This apparatus consists of a spirit lamp, which is worn on the hip supported by
straps, one to fit round the waist, the others from the shoulders. Over the wick
and burner of the lamp is placed a perforated cone with a stub or screw on the
upper end; this stub is solid, having a thread on its circumference, on which screws
an arm of any required length.
A cylinder of any suitable size, through which the heated air passes, is made to
slide on the arm by means of an opening left for that purpose, with a tube of about
one inch long projecting from near the lower end of the cylinder; this tube has a
valve opening inwards. At the upper end of the cylinder is a tube of india-rubber
or other suitable material, which is connected with a hollow brass ball enamelled
inside, and which is united in its centre by a flange, which may be opened and
closed at pleasure; the purpose and object of this ball is to contain a sponge, which
may be impregnated with any medicinal substance; to this ball is attached another
piece of india-rubber tubing, which is connected with a respirator having a valve
opening outwards; the respirator is fastened on the face by means of an elastic
band, and which covers both mouth and nostrils.
The object of the cylinder sliding on the arm is to regulate the heat by bringing
it closer to or farther from the lamp.
I do not limit myself to the means before described of heating respired air as I
may use other means, such as a taper, or by means of igniting a wire of platinum
by electricity. The essential feature of the Invention being breathing warm air by
means of the apparatus before described.

the said Noble Seward in the Great Seal Patent Office on the 20th March
1877.
NOBLE SEWARD, of Riversdale, Templeogne, in the County of Dublin, Ireland,
M.D. "A NEW MODE OF AND APPARATUS FOR BREATHING WARM AIR."
The object of this Invention is to enable a person at any time and in any placo
of breathing air at any temperature which may be considered necessary, and this
Invention consists of an apparatus attached to and worn on the body, which not
only allows them to breath warm air but also air impregnated with medicinal
substances.
This apparatus consists of a spirit lamp, which is worm on the hip supported by
straps, one to fit round the waist, the others from the shoulder. Over the wick
and burner of the lamp is placed a perforated cylinder or cone, with a stud or
screw on the upper end; this stub, stud, or screw is solid, having a thread on its
circumference, on which screws an arm of any required length.
A cylinder of any suitable size, through which the heated air passes, is made to
slide on an arm by means of an opening left for that purpose, with a tube about
one inch long projecting from near the lower end of the cylinder; this tube has a
valve opening inwards; at the upper end of the cylinder is a tube of india-rubber
or other suitable material, which is connected with a hollow brass ball enamelled
inside, and which is united in its centre by a flange, which may be opened and
closed at pleasure; the purpose and object of this ball is to contain a sponge, which
may be impregnated with any medicinal substance; to this ball is attached another
piece of india-rubber tubing, which is connected with a respirator having a valve
opening outwards; the respirator is fastened on the face by means of an elastic band,
and which covers both mouth and nostrils.
The object of the cylinder sliding on the arm is to regulate the heat, by bringing
it closer to or farther from the lamp; this cylinder becomes heated by its contact with
the bar, and it can also be brought as near to the lamp to increase the heat or removed
along the bar to any distance from it to moderate the temperature; the atmospheric
air enters and passes through the cylinder, and through the globe which contains the
sponge impregnated with the medicinal matter desired; the vapour or heated air then
passes into the respirator, which contains a valve opening outward, and through
which the air after respiration passes. No air can enter the lungs except what
passes through the cylinder.
And in order that my said Invention may be properly understood I will proceed
to describe the same with reference to and by the aid of the annexed Drawings.
Sheet 1, Figure 1, is a perspective view of the improved apparatus for breathing
warm air, and is shewn attached to a person in the manner in which it is intended
to be worn.
Sheet 2, Figure 2, shews a sectional elevation of the respective portions of my
apparatus.
Figure 3 shews a sectional elevation of the ball or spherical chamber containing
the sponge impregnated with any desired medicinal substance.
Figure 4 shews a sectional elevation of a cylinder or tube in which the air is
heated after its admission through the inlet valve in the branch of the same.
Figure 5 shows a cross sectional elevation of a spirit or other kind of lamp worn
on the hip, and from which heat is communicated through a bar to the aforesaid
cylinder, shewn in Figure 4.
a is a crescent-shaped spirit or other kind of lamp worn on the hip and attached
to that part of the person, firstly, by a suitable strap b passing over the convex
portion of the lamp through the eyes c, c, on the same, and then round the waist
of the wearer and secured by a buckle; secondly, by a strap d passing over one
shoulder, the ends of which strap are attached to the eyes e, e, in the top of the lamp
by means of the spring hooked swivels f, f.

page_text: The clothes of the wearer are protected from actual contact with the flame of the
lamp by the perforated cylinder g, which is placed over the burner. On the top of
the perforated cylinder is a stud to which the boss h of the arm i is attached, and
secured thereto by the winged screw j. There is a short tube a¹ with a screw
cap a for replenishing the lamp with spirit.
The
The attachment between the arm i and the cylinder g is so constructed that the
arm i can turn on the cylinder g and adapt itself to the size of the wearer.
cylinder or tube k has on its lower end a projection k¹, which has a hole in it of a
suitable size to fit on the arm i, and admits the cylinder k to slide on that arm.
On the branch of this cylinder k is placed the inlet valve, which is protected
from damage by a removable cap m having openings m¹ at its side to admit air.
According as it is desired to raise or lower the temperature of air passing through
the apparatus so this tube k is brought nearer to or removed farther from the lamp a.
The tube k can be secured at any determined position on the arm i by the set
screw n. The armi is split about half its length to temporarily hold the tubes
before tightening the set screw.
The warm air travels from the tube k to the spherical receptacle through the
elastic tube p, which connects the two former together, and onward through
another elastic tube connection r with the respirator q. The receptacle o is union
jointed in its centre, and in it is placed a sponge o¹, seen in Figure 3, saturated
with any medicinal substance desired, so that the warm air may be charged with
the same in passing through the sponge in the receptacle. The respirator q has an
outlet valve in its short tube 8 attached to it, and has a similar protecting cover t
with openings t¹ in it in a similar manner to the cover for the inlet valve already
described. That the respirator q may mould itself to the formation of the face of
the wearer it has round its edge that comes in contact with the face a very pliable
elastic tube u, which may be more or less inflated by means of the small tube v;
in this latter tube v is placed a tap v³, so that air may be retained in the tube u,
as desired. The respirator is attached to the face by means of an elastic strap w
which passes round the back of the head and has its ends attached one on each side
of the respirator q.
In Figure 4, Sheet 2, the construction of the inlet valve is more fully shown; this
valve is kept to its seat 2 by the slight pressure given by the spiral spring ³, but
it readily rises off its seat on the wearer inhaling.
Also Figure 2, Sheet 2, shews the formation of the outlet valve s¹; this valve,
apart from its being an outlet instead of an inlet valve, is constructed in a similar
manner to the inlet valve before described, namely, it is retained by the slight
pressure of the spring 82 to its seat 83, but is easily opened by the pressure of the
exhaling breath of the wearer.
Having thus described the nature and object of my said Invention I would
observe in conclusion that I do not limit myself to the means before described of
heating respired air, as I may use other means without departing from the general
principle of my Invention, such as a taper, or by means of igniting a wire of platinum
by electricity, or I may heat the bar by means of an electric lamp; but that what
I claim and desire to be secured to me by the herein-before in part recited Letters
Patent is,
First. The mode of breathing warm air by means of the apparatus attached to
the person, substantially as herein-before described, and as shown and illustrated
on the Drawings, or any mere modification or imitation thereof.
In witness whereof, I, the said Noble Seward, have hereunto set my hand and
seal, this Twentieth day of March, in the year of our Lord One thousand
eight hundred and seventy-seven.
NOBLE SEWARD, M.D. (L.S.)
