heating of the tube while the same is in use.
With the foregoing and other objects in view,
our invention consists in certain novel features
of construction and arrangement of parts that
35 will hereinafter be more fully described and
claimed and illustrated in the accompanying
drawing, in which:
Fig. 1 is a sectional perspective view of a tube
constructed in accordance with our invention and
40 having a single partition that divides the space
within the tube of the two chambers.
Fig. 2 is a sectional perspective view of a tube
that is formed in two parts that are integrally
connected.

Fig. 3 is a sectional perspective view of a tube
having two chambers formed therein.
Fig. 4 is a sectional perspective view of a tube
having four chambers.
Fig; 5 is a plan view of a tube constructed in
50 accordance with our invention and having its
forward end shaped so as to be readily inserted
into different cavities of the body.

the center of a tube constructed in accordance

cally the same area and capable of containing a
relatively large quantity of gas.
tubes I3 of fused quartz or silica, each tube hav- 25 I
ing a ?at side or face and the two ?at sides or
faces being placed together and welded.
This
construction provides a tube having two longi
tudinally disposed gas chambers.
In the construction illustrated in Fig. 3, a rod 30
M of fused quartz or silica is provided with two
longitudinally disposed parallel chambers i5.
Obviously the rod may be provided with three or
more longitudinally disposed parallel chambers
and in Fig. 4 is shobvn a rod having four cham- 35
bers.
In all cases the structure is that of a quartz
rod having a plurality of longitudinal bores ex
tending therethrough, the bores communicating
with each other at the outer or distal end of the 40
rod. Thus by inserting the electrode iii in each
of the bores the electrical discharge between the
electrodes will follow the path of one of the bores
to the outer or distal end of the rod and back
through the other bore to the second electrode. 45
The cross sectional area of the bores being sub
stantially the same, the discharge path so formed
is of substantially constant cross sectional area,
thus insuring that the resistance to the discharge
will be substantially the same throughout the 50
extent of the rod. The electrodes may be formed
in separate chambers of quartz sealed respec- ~
tively to the rod to communicate with the bores
therein.

The electrodes it are formed of solid material 65

having a high degree of electric current conduc
tivity and-they are ?xedly secured in any suit
able manner in the rear ends of the legs of the
elongated U-shaped chamber within the tube and
said electrodes are disposed in longitudinal align
ment with the legs of said U-shaped chamber in
order that the current that passes to and from
said electrodes may have direct ?ow through the
inert gas that ?lls the chamber within the tube.
A small opening is made at the rear end of the
10
tube to permit connection to a suitable pump and
after the chambers within the tube have been
exhausted of all foreign gases by means well
known to those skilled in the art, a suitable in
15 ert gas, for instance, argon or neon, or a suitable
combination of inert gases is discharged into the
opening and after a drop or two of mercury is
delivered through said opening, the same is
sealed. This sealed opening is designated by
20 the numeral II.
In practice we prefer to use a quartz or fused
silica tube for the reason that such tube permits
the desired rays to pass from the luminous gases
contained within the tube while an electric cur
rent is passing therethrough and as the appara
tus in operation develops a temperature of less
than.l20° F. it is not necessary to employ any
cooling means such as a circulation of cool air
or water for the purpose of counteracting heat
80 and maintaining the apparatus at a usable tem
perature.
We have demonstrated in practice that our im
proved apparatus produces positive ultra-violet
rays or waves such as are commonly used in ther
apeutic treatments and which are considered
highly effective and bene?cial and these rays or
waves are produced without the development of
su?lcient infra-red or heat rays that would other
wise render the apparatus impractical for use
and an inert gas ?lling said chambers to a pres
sure sumcient to support an electrical discharge
between said electrodes.
2. In an apparatus for producing ultra-violet
rays, a substantially straight transparent tube,
a partition disposed within the tube extending
from the sides thereof and sealed to said sides
and dividing the space therein into a plurality
of longitudinally disposed chambers of substan
tially equal area, an electrode sealed into each 10
chamber or sealed into tubular extensions lead
ing therefrom at one end of the tube and the
two chambers in the tube communicating with
each other at the distal end of the tube so as to
form a continuous chamber from one electrode 16
to the other and an inert gas placed within said
tube at a pressure su?‘lcient to support an elec
trical discharge between said electrodes and with
a small quantity of mercury in said chambers.
3. An an article of manufacture, a therapeutic 20
light ray tube comprising a substantially straight
body formed of quartz, one end of which body is
slightly enlarged, a rigid partition arranged with
in said body and sealed to said body on each side
and dividing the space therein into a plurality
of longitudinally disposed chambers of substan
tially equal cross sectional area, said partition
being connected to the body at the enlarged end
thereof, the opposite end of the partition being
spaced apart from the corresponding end of the
body so as to establish communication between
the chambers within said body thereby providing
a continuous chamber within said body that is
substantially twice the length of said body, elec
trodes sealed within the ends of the continuous -
chamber ‘that terminate in the enlarged end of
the body of the tube, and an inert gas ?lling said
chamber at a pressure su?lcient to support an
electrical discharge between said electrodes.

A particularly desirable feature of our inven
tion is that the tube when properly constructed
and ready for use comprises a straight or slightly
curved body that has the form of a cylindrical
45 tube and by virtue of such form the tube may be
readily inserted into the smaller cavities and
ori?ces of the body, and the longitudinally dis
posed partition or partitions within the body of
the tube divide the space therein, into a contin
uous chamber that is double the length of the
'tube thus, in effect producing a double ray of
gitudinal bores extending therethrough and. in
tercommunicating with each other at the distal
end of said rod and within the end of said rod, a
plurality of electrodes, one for each of said bores
mounted at the other end of said rod, each elec
trode being located within the end of the bore
in which it is located,- and an inert gas ?lling
said bores at a pressure sumcient to support an
electrical discharge between said electrodes.
5. In a gas ?lled lamp for electric discharge,

an elongated quartz rod having a plurality of

parts of our improved apparatus for producing
