We, AXEL ÜRLING, of No. 7, Engelbrektsgatan, Electrician, and CARL GUSTAF
GEORG BRAUNERHJELM, of No. 19, Engelbrektsgatan, Colonel, both of Stockholm,
in the Kingdom of Sweden, do hereby declare the nature of this invention to
be as follows:-
The present invention relates to a convenient and practical electrical con-
denser as well as an apparatus based on the construction of said condenser and
adapted for the production of powerful waves of electricity.
An apparatus of this kind is shewn in the drawing annexed, in Fig. 1 in a
side-view (partly in section) and in Fig. 2 in a top-view.
The electrical condenser consists essentially of a collection of conducting
objects enclosed in a casing of metal or other conducting material, said
conductors being insulated both from each other and from the casing a by
a thin coating of non-conducting material. The conductors are suitably small
metal balls, and as insulating material serves oil, paraffine, or the like, which
completely fills the space between the small balls. The conductor € passes
through an aperture in the casing a into the interior of the latter and is insu-
lated from the said casing by means of a tube d of non-conducting material.
The small balls in this condenser act in the same munner as one of the
coatings of a plate or Leyden jar, and the oil acts as the dia-electric medium.
Owing to the large number of balls the capacity of the condenser is very great.
The suspension piece f, which is made of non-conducting material, may
suitably be provided with a bore-hole, and, at one end, with a screw h, so as
to admit of filling the casing a, with balls and oil on removing the screw h,
or relieving it of its contents.
The apparatus for producing powerful electric waves, constructed in accor-
dance with this invention, consists of two condensers of the above description
arranged at some distance apart and insulated from each other, said condensers
being located in oil or other liquid insulating material. The insulating material
is contained' in a box of glass or other non-conducting material. One (or
both) of the condensers is secured to a movable plate m, so that the distance
between the condensers can be regulated at will. Whenever the condensers

parts of their outer surfaces.

Improved Electrical Condenser and Apparatus for Producing Powerful
Electric Waves.
We, AXEL ORLING, of 7, Engelbrekisgatan, Electrician, and CARL GUSTAF
GEORG BRAUNERIIJELM, of 19, Engelbrektsgatan, Colonel, both of Stockholm,
Sweden, 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:—
The object of the invention is to produce convenient electrical condensors
as well as cheap and efficient radiators for producing powerful electrical (s.e.
Herz) waves (discharges).
The invention consists, briefly, in converting the knobs of a radiator of the
class described into condensers by making them hollow, and filling the same
with conducting. bodies, such as shot, and a dielectric medium, such as oil,
between said bodies. The invention also consists in the combination and
arrangement of parts of the radiator hereinafter described and claimed.
The invention is illustrated in the drawing left with the Provisional Appli-
cation, in which Figure 1 is a side-view partly in section of a radiator of the
kind above referred to, and Fig. 2 is a top-view of the same.
The electrical condenser consists essentially of a collection of conducting
objects enclosed in a casing a of metal or other conducting material, said
conductors being insulated both from each other and from the casing a by
a coating of non-conducting material. The conductors are suitably small
metal balls, and as insulating material we use oil, paraffine, or the like, which
preferably fills the space between the small balls. The conductor e passes
through an aperture in the casing a into the interior of the latter and is insu-
lated from the said casing by means of a tube of non-conducting material.
The small balls in this condenser act in the same manner as the plates of a
condenser connected in series and the oil acts as the di-electric medium.
The radiator for producing powerful electric waves, constructed in accor
dance with our invention, consists of two condensers of the above description
arranged at such a distance apart as to serve as the discharge knobs and insu-
lated from each other, said condensers being located in oil or other liquid
insulating material to insure a powerful discharge. The insulating material
is contained in al box of glass or other nonconducting material
from the Cover of which the condensers may be suspended. One (or
both) of the condensers is secured to a movable plate m, so that the distance
between the condensers can be regulated at will to suit the violence of discharge
desired. It need hardly be mentioned that for operating the said radiator,
the conductors are connected to the terminals of a Holz machine or the like.
Whenever the condensers have received a certain charge, the discharge takes
place between the adjacent parts of their outer surfaces.

page_text: An aperture is provided in the cover for the filling and emptying of
the box.
The piece serving to suspend the condensers (knobs) preferably of non-
conducting material, may suitably be provided with a borehole, closed by a
screw h, so as to admit of filling the casing a with balls and oil, on removing
the screw, or relieving it of its contents.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, we declare that.
what we claim is:-
1. An electrical condenser, consisting of a hollow metallic casing enclosing
a dielectric medium, such as oil, and a number of small metallic bodies which
are insulated from each other by said medium, and a conductor passing tightly
through said casing into the mass of bodies but insulated from said casing,
substantially as set forth.
2. A radiator for electric waves, consisting of a box containing a dielectric
substance, such as oil, and two condensers suspended in the said medium so
as to at the same time serve as discharge knobs, substantially as and for the
purpose set forth.
3. In a radiator for electric waves the combination of a box containing a
dielectric medium, such as oil, and two condensers, suspended in said medium
so as to at the same time serve as discharge knobs, each consisting of a hollow
metallic casing enclosing a dielectric medium, such as oil, and a number of
small metallic bodies which are insulated from each other by said medium,
and a conductor passing tightly through said casing into the mass of bodies
but insulated from said casing, substantially as and for the purpose set forth.
