To @ZZ whom it may concern.'

Be it known that we, HERMAN BOEHM and FREDERICK H. VAPPLER, citizens of the United States, residing in the borough of Manhattan, in the city, county, andState of New York, have invented an Improvement in Vacuum-Tubes, of which the following is a speci- Y coacting, connecting, and supporting devices.

Our present improvement, like the device of said patent, is a vacuum-electrode, of vitreous material, employed in electrotherapeutics for 2o effecting electrical asepsis and stimulation by Y passing' high-tension currents through .said electrode, and thereby decomposing the air surrounding the same into ozone, which in proximity to the diseased surface quickly oXidizes all toxic matter present therein.

In carrying out our invention the sealed end of the vacuum-'electrode is of reduced area from the major portion of the electrodetube, and in a portion of intermediate diameter there is a screw-thread pressed into the glass or vitreous material. The tubular handle is to be of any suitable insulating material--such, for instance, as hardrubber-hav# ing an interiorly-threaded tubular metal end,

preferably of slightly larger diameter than the main portion and into which the threaded .portion of the vacuum-electrode screws with the reduced end farther Within the tubular handle. This handle is adapted for interchangeable vacuum-electrodesMthat is, vacuum-electrodes where the bulb or free ends are of different shapes, according to the use to which the vacuum-electrodes are to be put. A unipolar terminal is sealed in the vacuumelectrode close to the threaded portion, and

the part thereof that projects is in the surface glass and contacts with thetubular metal end. An adjacent terminal support is secured tothe said tubular metal end.

In the drawings, Figure 1 is an elevation 5o representing our improvement. Fig. 2 is a longitudinal section andpartial elevation of the same, and Fig. 3 is a cross-section and partial elevation at a' of Fig. 2.

The electrode comprises two essential parts-a part of vitreous material containing a vacuum, and a handle. The part of vitreous material com prises a tube a, of'glass, a bulb end d, blown to the desired form or shape.l according to the disease to be treated. The 6o same also includes a reduced threaded portion c2 and a further reduced paralled-sided part as and sealed end a4. The threaded part a2 is pressed into the glass,vand between the same in its diameter and the tube of glass c there is a tapering portion, and between the threaded portion a2 and the further reduced parallel-sided portion a" there is also a tapering portion, and 2 represents a sealed-in unipolar terminal. The wire forming this terminal 7o projects within the vacuum-tube and also eX- tends outside, where the same is bent over and partially embedded in the surface glass.

L represents a handle, of suitable insulating' material, preferably hard rubber, although we do not limit ourselves in this respect, as any suitable insulating material may be employed. We have shown the handle in the drawings as broken off at one end, because the same may be of any desired length. One 8O vend of this insulating-material handle b is preferably slightly enlarged, as shown in the drawings, and placed therein is an interiorlythreaded tubular metal end the outer surface of which at one end is preferably of the 8 5 diameter of the enlarged portion of the tubular handle,'eXtends beyond the insulating' material of the handle, and is provided with a circumferential groove.

The interior diameter of the interiorly-,QOy

threaded tubular metal end is slightly in excess of the interior diameter of the main tubular handle, the threaded portion agreeing with the threaded portion a2 of the part of vitreous material. The parallel-sided part of vitreous material a3 is of slightly less diameter than the interior diameter of the tubular handle. Consequently when the part of vitreous material is brought into relation with the handle the part a3 is freely received into the tubular handle and the threaded. portion engages the threaded portion oi' the tubular metal end 2;', the parts screwing together, so that the inclined portions at the respective ends or' the threaded portion engage conforming inclined portions at the outer end of the tubular metal end b and at its inner end, the sealed-in unipolar terminal 2 at the same time forming metallic and electric contact metal to metal with the end of the tubular metal end b. The parts are thus connected quite iirmly and rigidly for the uses to which the electrode is to be put and so firmly as to prevent accidental separation.

In the groove surrounding the end of the tubular metal end b' is a wire ring c' and adjustable terminal support c, the terminal support being adapted to receive one end of a lead-wire or electric conductor. This adjustable terminal and the wire ring connected therewith may be turned around upon the tubular metal end b to be brought into any desired position where the same will be most out of the way of the operator.

We do not herein limit ourselves to the employment of an interiorly-threaded tubular metal end b nor to the screw-threaded portion a2 pressed into the tube of vitreous material, as any well-known means or' removably connecting these parts so as to prevent accidental separation may be employed instead of the precise manner shown.

1n the present case, as in the former patent, the high-tension currents that are necessary to operate the vacuum-electrode may be produced in any desired manner, and they are in the present case produced in substantially the same manner as is described in the aforesaid patent, in connection with which a Ruhmkorill coil may be employed, one terminal or' the secondary being connected electrically to a plate upon which the patient to be treated is placed and the other terminals of the secondary insulated. The current is then complete from the plate upon which the patient is placed by the patient, the vacuum-electrode, and to the insulated terminal of the secondary through the air, and in treating the patient the operator grasps the handle and employing the vitreous-material electrode with the desired form of end moves the same over the diseased parts and is not hampered by wires or electrical connections.

We claim as our invention- 1. An electrode for therapeutic purposes, comprising a part of vitreous material containing' a vacuum with one end reduced in diameter, a handle of insulating material adapted to receive said reduced end, and means for connecting the parts to prevent accidental separation.

2. An electrode for therapeutic purposes,

comprising a part. of vitreous material containing a vacuum with one end reduced in diameter, a sealed-in unipolar terminal adjacent to this end, a handle of insulating material having a tubular metal end received within one end of the handle, and said parts adapted to receive the reduced end of the electrode or' vitreous material, and means for connecting the parts to prevent accidental separation.

3. An electrode for therapeutic purposes, comprising apart of vitreous material containing a vacuum with one end reduced in diameter, a sealed-in unipolar terminal adjacent to this end, a'handle of insulating materialA having a tubular metal end received within one end of the handle and said parts adapted to receive the reduced end of the electrode of vitreous material, means for connecting the parts to prevent accidental separation, and means for connecting one end of a lead wire to the tubular metal end.

4. An electrode for therapeutic purposes, comprising a part of vitreous material containing a vacuum with one end reduced in diameter and sealed and with an adjacent part of intermediate diameter having a screwthread pressed therein, a handle of insulating material having in one end an interiorlythreaded tubular metal end, said parts adapted to receive the reduced end of the part of vitreous material so that the screw-threads interlock and the reduced end passes farther within the handle to hold the parts in their connected relation and prevent accidental separation.

5. An electrode for therapeutic purposes, comprising a part of vitreous material containing a vacuum with one end reduced in diameter and sealed and with an adjacent part of intermediate diameter having a screwthread pressed therein, a sealed-in unipolar terminal, a handle of insulating material having in one end an interiorly-threaded tubular metal end, said parts adapted to receive the reduced end of the part of vitreous material so that the screw-threads interlock and the reduced end passes farther within the handle `to hold the parts in their connected relation and prevent accidental separation, said unipolar terminal making metallic and electrical contact with the inner surface of the tubular metal end when the parts are connected. l
