PROVISIONAL SPECIFICATION.
Improvements in Electro-medical Apparatus.
I, CORNELIUS BENNETT HARNESS, of 52 Oxford Street, in the County of Middlesex,
Electrician, do hereby declare the nature of this invention to be as follows:-
―
My invention relates to electro-medical apparatus whereby air charged with, or
subjected to the action of electricity can be breathed or inhaled.
According to my present invention I construct the apparatus as follows, viz. :-L
provide a tube in which are arranged two or more rods of conducting material designed
to be connected to the poles of a Wimshurst. or other electrical machine.. Each of
these rods is provided at its inner end with a suitable electrode which may have the
form of a sphere, dise or cone, or any other suitable form. The said rods are provided
with means for adjusting them towards or away from each other. The tube is pro-
vided with a suitable mouthpiece and with an entrance or inlet for the air so
arranged that the air entering the apparatus will pass through the space between the
electrodes.
:
I preferably provide a number of interchangeable eléctrodes of different forms
adapted to fit the aforesaid rods.
I provide in the mouthpiece or in any other convenient part of the apparatus a glass
disc or window beneath which is placed a piece of chemically reactive paper, which is
visible through the said glass. By this means I provide for indicating the chemical
changes or modifications which may be produced on the paper under the influence of
the air charged with electricity, thus showing the extent to which the air has been
acted upon.
The construction of the apparatus may be modified in various ways provided the
electrodes connected to the two poles of the machine are arranged in proximity to each
other and in a suitable position relatively to the mouthpiece.

COMPLETE SPECIFICATION.
Improvements in Electro-medical Apparatus.
I, CORNELIUS BENNETT HARNESS; of 52 Oxford Street, in the County of Middlesex,
Electrician, 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 :-
My invention relates to improved electro-medical apparatus of the kind or class
described in the Specification of former Letters Patent granted to me and dated
October 24th, 1889, No. 16,816, that is to say, electro-medical apparatus whereby air
or other gases charged with, or subjected to the action of electricity can be breathed
or inhaled.

.
According to my present invention I construct such apparatus as follows, riz. :-I
provide a tube in which are arranged two or more rods of conducting material designed
to be connected with the poles of a Wimshurst or other electrical machine. Each of
these rods is provided at its inner end with a suitable electrode which may have the
form of a sphere, disc or cone, or any other suitable form. The said rods are provided
with means for adjusting them towards or away from each other. The tube
provided with a suitable mouth-piece and with an entrance or inlet for the air, so
arranged that the air entering the apparatus will pass through the space between the
electrodes.

page_text: In the accompanying drawing :-
Figure 1 is a longitudinal central section of one form of my improved apparatus,
some of the parts being shown in side elevation..
Figure 2 shows in side elevation, various forms of electrodes adapted for use in my
improved apparatus.
A is a tube which is provided midway between its extremities with a mouth-piece A¹
and with an orifice or nozzle A² for the admission of air. B, B, are the conducting
rods to the inner extremities of which are attached the electrodes C. The outer
extremity of each rod B is provided with a knob or handle D. The said conducting
rods B extend through and are fitted to slide longitudinally in caps or plugs E and
tubes E' attached to the said caps, which act as guides for the said rods.
The tube A, the mouth piece A¹ and nozzle A are formed of vulcanite, ebonite or
other suitable insulating material. The rods B should be of brass or other conducting
material.. The caps or plugs E are screwed or otherwise secured in the extremities of
the tube A so as to prevent the entrance of air into the said tube at its ends.
The electrodes (serve for the discharge of electricity into the air entering through
the nozzle A. These electrodes may be of any suitable form for example of either of
the forms shown in Figure 2.
The action of the apparatus is as follows:-The two rods B being connected by
means of wires or conductors attached to loops or eyes B¹ on the said rods, with a
suitable source of electricity, such for instance as a Wimshurst Induction machine,
are caused to approach each other till the discharge between the electrodes C is
sufficiently intense, to produce the required degree of a electrification of the air
entering the apparatus through the orifice A³. The fact that the air is sufficiently
charged may be known by the effect experienced by the person breathing or inhaling
the air through the mouth-piece A', or it may be indicated by a piece of chemically
sensitive paper in the apparatus, which can be seen through a glass disc or window F,
the depth of colour acquired by the said paper being an indication of the intensity. of
the electrical discharge from the electrodes C.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it understood that
I claim -
First. An apparatus for the inhalation of air or other gases charged with or sub-
jected to the action of electricity, comprising electrodes arranged in combination with
a mouth-piece and an air-admission orifice and adjustable towards and away from
each other, for the purpose above specified.
Second. The improved electro-medical apparatus (with or without the means for
indicating to the person using the same when the action is sufficiently energetic)
constructed substantially as described with reference to the accompanying drawing
and operating as, and for the purpose, above specified.
