ELECTROMAGNETIC WAVE BATH.

Specification of Letters Patent. Patented J une 6, 1922.

Application filed September 14, 1921. Serial No. 500,560.

T 0 all whom it may concern: 4 Be it known that I, WILLIAM S. BENSON, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved ElectromagneticWave Bath, of which the following is a full, clear, and exact description. The. object of this invention is to provide an electro-magnetic Wave bath for treating the cells of the body and which has in conjunction therewith means for treating the skin to ,destroy germs and'means for applying electricity to the difierent parts of the A further object is the provision 'oi'an BlGCtIG-Hlitgllfiiilc wave bath provided with means for varying the strength of the magnetic torce between certain limits at a rate equal to the heart beats of the patient. These objects are accomplished by providing a container and means for'causing lines of magnetic force, which are continu ally reversing their direction, to flow therethrough, and means for varying the strength of this magnetic force, and means inconjunction with the container means for generating light. rays which have a germic dal effect in different skin diseases, and means for applying electricity directly to different parts of the body.

These and other objects of-the inventionwill be more clearly understood from the following detailed description and accompanying drawings.

Referring to the above-mentionedfigures; this apparatus as shown in Fi ure 4 consists of a container 10 which 1s made of cylindrical shape' Thi 'container is made of a non-magnetic material such as brass. The reason for this will appear later in the specification. Located around this nonmagnetic container is a layer of mica or some other insulating material 11. Wound about the container over the insulating material i a conductor of electricity 12 of some satis-- factory type to form an electromagnetic field within the container. This-coil is made up of. a great number of turns dependingupon the-strength of the magnetic force that-1t lating material 13 and the various layersare encased by means of an iron cylinder 14.

Surrounding the elec- This encasing member might possibly be made of other material than iron but this is most'satisfcactory for the purpose. The cylinder, 14 is supported on a plurality of legs 15.

Located inside of the container 10 is a lining 16 which carries a plurality of lamp sockets 17 which are connected with a source of electric current in any usual manner. Mounted in these sockets are lamps 18. These lamps are selected from amongst those that generate light rays of different colors in the spectrum. it is well known that light rays of certain colors are destructive to germs and these lights are provided for generating rays for treating skin diseases.

n of vibration. the various colors of the spectrum are employed through the medium of colored lights. These different colored vibrations produce difierent efiects, such as thermal, germicidal, stimulative and seda-' tive., The s ecial feature of application of these vibratlons of color is that they will also be alternating to conform to the normal orderto be able to employ distinct rates i beat of the heart of the patient being treated.

Referring to Figures 6, 7 and 8, a regulator for controlling the amount of current passing throu h the coil about the container is shown. In Tigure 8 a diagram of the connections is disclosed as containing coils 21, 22, 23, 24, which, when alternating current is used, operate, when in circuit as choke coils to cut down the strength of the current. The terminals of these coils are connected to contact points 25, 2e, 27, as, ea, 30, 31, a2, 33, 34 by means of wires 36 to 45, inclusive, as shown in the diagram. The conductor 12 which is wound about the container 10 has one terminal connected to the contact point 25 by means of a conductor 48, and the other terminal to a terminal of a source of supply of alternating current by means of the conductor 47. The other terminal of the source of supply is connected by means of a conductor 46 to the shaft 49. Mounted on the shaft 49 is an arm which serves to connect it to any one of the contact points 25 to 34, inclusive. It will be seen that one or all of the choke coils 21 to 24, inclusive, may be connected in series with the conductor 12 in order to vary the current flowing through the said conductor. As the arm 35 rotates in a counter-clockwise direction one coil is added for each ste until the arm reaches contact point 30. fter that until the arm reaches contact point 34 one coil is cut out upon each step thus increasing the amount of current flowing through the conductor 12. Thus for every rotation of the arm 35 the current flowing in the conductor 12 is decreased from the maximum amount to the minimum which flows when all the coils are connected in series with the conductor and then increased to the maximum which flows" when all the coils are cut out of the circuit. These coils are enclosed in a box 54 and may have a core 53 extending throu h them. The arm 35 is rotated by means 0 a motor 51connected to a pulley 50 by a belt 52. The pulley 50 is fixed to the shaft 49. The speed of this may be controlled so as to rotate the arm 35 at any desired speed. With such a device it is possible to vary the current flowing in the conductor 12' to certain limits periodically and by properly controlling the speed of the motor or the gear ratio between the motor and rotating'contact arm the number of periodical variations may be made to conform to the number of heart beats of the patient. Any number of coils might be provided in the regulator to obtain a more gradual or a more abrupt increase or decrease in current in the conductor 12.

The maximum current flowing in the conductor 12 is obtained when the arm 35 engages the contact point 25 or the con- '49, arm 35, con uctor 12 andback to conductor 47 or through conductor 46, shaft 49, arm 35, contact point 34, conductors 45 and 36, conductor 12 and back through conductor 47. The minimum amount of current flows when the arm 35 contacts with either of the contact points 29 or 30. When the arm 35 contacts with the contact point 29 the current flows through conductor 46, shaft 49, arm 35, contact point 29, the coils 24 to 21, inclusive, conductor 12 and back through the conductor 47. As the arm 35 is moved over contact points 25 to 29 the current flowing in the conductor 12 is gradually decreased and as the arm 35 moves over contact points 30 to 34 the current flowing is gradually increased. As the current flows through conductor 12 lines of magnetic force are created about the conductor. These lines of magnetic force permeate the space within the container and are reversed in direction every time the curent flowin in the conductor reverses its direction. T e container 10 is made of non-magnetic material so that the lines of magnetic force will permeate the space in the container instead of flowing through the walls of the container.

One end of the casing 14 has a cap' 55 fitted thereon. This cap 55 has a plurality of holes 56 extending therethrough. .Mounted in each hole is a shaft 57 to which is connected a core 58 of an inductance coil 59. This inductance coil is rovided with two terminals 60 and 61 which may be connected with suitable body electrodes, for applying electricity directly to the different parts of the body of the patient. The induced current in the inductance coil 59 may be varied by adjusting the position of the coil. If it is desired to obtain a greater current the coil is moved inward into the portion of the container surrounded b the conductor 12 as indicated in dotted lines in Figure 2. This current can be utilized to gently exercise each and every muscle of the bod by applying it directly to cause wave-1i e contractions and relaxations of the body tissue. The special construction of this apparatus enables the regulation of the current'to such a fine degree that the Wave-like im ulses are absolutely painless and non-irritating. Another feature of application of this current is'that its strength will periodically vary between certain predetermined limits ac-' cording as the current is varied in conductor 12, and as above stated the current in is bathed with alternating electrical vibrations. -c

A certain amount of heat Wlll ordlnarrly be developed by the magnetic coil 12 and the lamps 18 will also supply their proportionate heat to the interior of the treating cell or container so that the patient will be subjected to the effect of heat, as well as the application of light, magnetism and current electricity. Ordinarily, the lights will be connected in circuit with and governed by the controller so that the light and heat, as well as the magnetism and current electricity will be applied in the form of waves of more or less gradually increasing and decreasing intensity. lVhen these so-called waves of heat. light, magnetism and ourrentelectricity are brought into time with .the heart beats of the patient, asby properly controlling the speed of the controller motor, a most effective treatment results. Further it is found that if the heart beats are abnormal this ccndition can be improvedby timing the waves to what would be normal for the person under treatment, this exerting a corrective effect and serving to restore conditions to the normal. The applied current electricity and the electromagnetic flux both being of periodically varying intensity, oo-
