        The Violet Ray is a pleasant, effective means of applying the wonderful power of electricity to the human body without pain, sensation or shock, and is without an equal in relieving pain and congestion, stimulating the circulation and restoring good health, vigor and youth.

        The Violet Ray is the ordinary electric current obtained from any socket, nebulized and split up into infinite parts and produced through glass applicators called electrodes, in a violet colored stream, hence its name, VIOLET RAY. A huge voltage of electricity is obtained and applied to the body or hair but without any shock, whatever, the only sensation being a pleasant warmth.

        Violet Ray Treatments surely relieve pain in any part of the body. The electrical currents penetrate every cell and tissue of the body, and tranquilize and soothe. Violet Rays stimulate and strengthen the vital organs, build up the natural forces, steady the nerves, and develop the general health and conditions of the body. High frequency electrical currents carry oxygen to the blood, thus purifying this vital body fluid. Violet Rays equalize the circulation in congested parts and restore bruised and inflamed tissues to normal.

        A Master Violet Ray is applied through vacuum applicators or electrodes made of annealed glass. These electrodes diffuse the electrical current in sprays of a beautiful deep violet color. These sprays or sparks vibrate to and fro, or oscillate at the rate of several hundred thousand times per second. This rapid vibration is what produces the pleasing, invigorating and corrective effects derived from Violet Ray Treatments.

        A few minutes' application each day, simply holding the applicator in the hand, furnishes a tonic to the system which does much to fight disease and keep the body in a healthy state. Inasmuch as prevention is to be desired a thousandfold rather than a cure, this one point alone makes the Master Violet Ray indispensable in your home.

        Many authorities state that impaired circulation of the blood causes most ailments. The Violet Ray by stimulating the circulation, thus wards off disease, saving you much unhappiness and suffering.

        With the knowledge that electricity, Nature's greatest health agent, was a vital factor in the treatment of various diseases of the body, there has been a constant untiring effort to improve the method of application and increase the power of this wonderful agent.

        The wide use of electricity produced through various types of apparatus finally led to the discovery of the Violet Ray, otherwise known as High Frequency, which has solved many problems and today furnishes the most efficient and powerful phase of electricity known for the relief and destruction of the various diseases and germs of the body.

        The Violet Ray offers a pleasant, effective means of destroying germs and banishing various diseases while building up the tissues and toning up the system generally. The Violet Ray while introducing all the power of electrical energy into the body, does so without the slightest pain, shock or contraction of muscles. In fact the application of the Violet Ray produces a pleasing sensation. The amazing results secured through Violet Ray treatment, immediately caused it to be accepted by the professions, and today you can hardly find any physician's office not equipped with Violet Ray Apparatus.

        Now this remarkable factor is made available to you for use in your own home, at a price within the reach of anyone. We have built an effective Violet Ray instrument that is the essence of simplicity, made so a child may operate it, and at the same time we have an instrument that produces the Violet Ray unexcelled by machines costing many times as much without the unique and practical features of our instruments.


        Violet Rays or High Frequency Currents benefit all living matter. Through the glass vacuum applicator light, heat, electric energy and ozone are created. These forces are uniformly, potent in relieving and eliminating human ailments. Violet Rays present a remedy upon which we can rely. They are positive and certain in action. They will reach where medicine does not and often cannot reach – yet they cause no pain, no disagreeable sensation, no discomfort. They furnish a soothing relief. They destroy germs and have a strong power over infection.

        The uses for the Master Violet Ray are practically unlimited. Not only are ordinary pains and aches removed, but deep seated ailments of long standing are often entirely eliminated.


    There is no danger with the Violet Ray. It can he applied to the most sensitive parts and the treatment is agreeable and exhilarating. You simply connect the machine to any convenient light socket on direct or alternating current and it is ready for any treatment. People were very skeptical about the claims that we made for Master treatments till they found that physicians not only strongly endorsed its use, but treated their patients with it with very gratifying results. You will find the Master in the office of many doctors. The Master Violet Ray in the home is good health insurance.



        A. A sedative, quieting or soothing effect can be obtained and is of great benefit in all nervous ailments. This effect can be produced locally by keeping the electrode in close contact with the part to be treated. Painful sensations can be relieved, irritated nerves tranquilized and soothed. Nervous disorders are quickly and beneficially influenced by a sedative treatment.

        B. A stimulating effect is produced when the electrode is lifted somewhat during the application or used through the clothing or a cloth which has been put over the part to be treated. The length of the stimulating sparks depends on thickness of the clothing or cloth placed between the electrode and the body. Uniformity in spark length is insured by the cloth.

        Stimulating treatments through clothing are very beneficial in rheumatism, lumbago, partial paralysis, etc. Skin disorders, where the circulation is impaired, are often greatly benefited by a slight stimulation. A single layer of a handkerchief produces enough resistance in such cases. An ordinary towel is best to use in chronic rheumatism and similar affections.




        If Nature has not endowed you with the charms that you desire, or if work and worry have left their lines in your face and figure, you can erase them with the Master Violet Ray. Rich, red blood is brought to the skin with the use of the Violet Ray. It nourishes the tissues and cells and brings the radiant hue of health and beauty to the skin. All facial blemishes quickly vanish.

        All modern beauty specialists use the Violet Ray in the treatment of the hair and skin.

    Treatment of Hair

        Practically every disease of the scalp and hair, such as dandruff, failing hair, etc., can be traced to the improper circulation of the blood flowing through the scalp. The Violet Ray when applied to the hair has a direct action on the tiny nerve and blood vessels, stimulating them to perform their proper functions. The ozone generated acts as a germicidal agent and destroys any organism present, making dandruff impossible. A few treatments will suffice to convince you of the wonderful results accomplished. It is a proven fact that persistent use of the Violet Ray will restore grey hair to its natural color.

        The use of the Violet Ray for a few minutes each day will make the hair thick, healthy and beautiful.

        As a beautifying agent the Violet Ray is unexcelled, as it brings a fresh glow to the skin, producing a clear youthful complexion. It quickly removes Pimples, Blackheads, Boils, Warts, an d other Blemishes.

        It removes Dandruff, Eczema, Itchy Scalp and Skin Diseases. Every woman should have this outfit in her home for use on the hair alone, aside from the other innumerable purposes to which it may be put.

        As a bust developer, the Master Violet Rays will be of material assistance. A special electrode suitable for the purpose is made.

        The Violet Ray Refreshes the Body. The results obtained through Violet Ray applications will be a revelation to you and in a remarkably short time will bring your body, health and appearance to that condition that Nature intended it should be.



        When the electrode is brought near the body the flow of Violet Ray is apparent in one direction only. That is from the applicator to the body. Actually. However, the direction of the flow alternates from the applicator to the body and then from the body to the applicator thousands of times per second. This causes the cells of the body to vibrate accordingly, which gives the effects of a massage, and tends to revive and invigorate the bodily tissues by rebuilding each individual cell of which it is composed. This is one of the most beneficial results of the Violet Ray.



        Three distinct methods of application are in general use according to the conditions present and the results desired.

        First – Local applications. Given with specific surface of orificial applicators made for that purpose.

        A beneficial warmth is induced by the action of the Violet Ray, the capillaries of the skin are stimulated. The local blood supply in the treated parts is increased during the application and for some time thereafter. Any local application with a vacuum electrode is an effective antiseptic, largely on account of the ozone developed.

        Local applications produce the desired result at the treated part quickly. They also benefit to a remarkable degree the entire system. The body is penetrated by radiant atomized electricity, restoring energy and vitality to the entire system.

        Second – General applications. Taken as electrification treatment for the effect on the general condition. The entire body is saturated with electrical energy by simply holding the electrode in the hand. This produces a sedative or quieting effect.

        Violet Ray High Frequency Currents have the tendency to establish a normal equilibrium of the entire nervous system. Arterial tension during a general treatment usually increases slightly while it falls a short time afterward. General treatments are recommended in all nervous disorders and diseases.

        Third – Indirect applications. Combines local and general treatments and requires two people. The party to be treated holds the instrument with the attached electrode. A second party then may draw with either hand, finger-tips, or another electrode, the high frequency current to the desired spot of the patient's body.




        One of the greatest benefit of the Violet Ray. is the fact that it can be used with such excellent results in local conditions. When the Master Violet Ray is applied to any part of the body, it gives to a certain extent a general treatment by stimulating the circulation. In treating local conditions, these results are greatly increased by giving a local treatment to the part affected. Suppose one is afflicted with rheumatic pain in the shoulder, you apply the Violet Ray treatment to the painful part. The result noted will be an immediate sensation of warmth. After a slight treatment, you will note that the part treated has become slightly reddened by the blood that is sent in response to stimulation secured from the treatment.

        These local treatments can be given to any part of the body locally with very good results.



        Neuritis, as commonly understood, is rheumatism of the nerves. In the treatment of this condition, the Violet Ray is unexcelled. Not only does the Violet Ray apply health but a permanent relief is secured by relieving the inflammation and removing the cause of the ailment.



        By causing the rich red health-laden blood to flow to the affected part and concentrated oxygen driven directly into the tissues, the inflammation is usually quickly overcome and a normal condition is secured.




        The Master Ozone Generator, shown on Page 19 may be used with any Master machine. This generator in connection with our outfits give the most satisfactory method of Ozone treatment known to science.

        A most essential form of treatment for asthma, bay fever, and all lung, throat and nose cases.




        Master Violet Ray machines have many features that make them superior to other Violet Ray machines produced. Due to their superior type of construction, which permits of the use of parts of ample size, they will operate continuously for a much longer period without overheating than any portable machine heretofore offered.

        The Condensors are large and of over-capacity in order to prevent breakdowns. The Coils are all wound over-capacity to prevent over-heating in continuous and hard usage. The insulation of the coils used is equal to that of very expensive machines.

        The range of adjustment is ideal and suitable for all treatments.

        All Cords are sparkless and there is no possible danger of shocks. The machines are instruments of marvelous simplicity and efficiency that operate on any alternating or direct current without adjustment, and are fool proof in construction.

        They are economical in operation. The power consumed is less than that used by the ordinary electric light.

        The Master reputation has been built by supplying the most superior product on the market. Extreme care in the selection of material, rigid inspection, skilled craftsmanship, and years of experience make Master Violet Ray Instruments stand out in a class by themselves.



        A very important feature of all Master Violet Ray machines is the special patented Master Electrode socket terminal which is a part of the resonator coil. Should the electrode break, the coil can simply be unscrewed from the hard rubber housing and the electrode end easily removed by inserting a screw driver or knife in the insertion, as shown in illustration.

        In the past, where the electrode has broken, it has been necessary for practically all users to take these to an electric shop or repair man to have the electrode end removed. This annoyance is altogether eliminated, both to the user and the dealer, by the patented Master Electrode Terminal socket which is found only on Master Violet Ray machines.

        The Ozone Generator is a special applicator designed for direct medication in nasal, throat, bronchial and lung effections.  It generates enormous quantities of ozone.  Ozone is a faint blue glas compound of oxygen and is formed by the passage of an electrical discharge through air.  Outdoors, we get ozone after a thunder storm and indoors the same effect can be produced mechanically with Violet Rays.

        Ozone treatments are very beneficial and excellent results are secured in all diseases of the Respiratory organs.  Influenza, Catarrh,  Bronchitis, Asthma, Hay Fever, etc., quickly show marked improvement from its use.

     The ozone permeates every cell, destroying germ life, and soothes the inflamed tissues.



        The Generator is pushed into the instrument handle, after filling the inhalant chamber one-fifth with inhalant solution, the current is turned on.  The left hand is then put around the ozone chamber while the other hand  actuates the pressure bulb at convenience.  The nostrils are placed over or tight against the nose-piece, and the ozone is forced down through the nose into the lungs by pressing the bulb.  The inhaling of the ozone should be deep and the air completely exhaled before taking another breath.  Inhalation may also be made through the mouth by changing the nose-piece for the mouth-piece.

        The inhalant solution contained in the upper chamber of the generator washes the ozone as it bubbles through it, allowing particles of it to be carried along in the form of vapor.  This inhalant solution is a splendid combination of essential oils which have a soothing effect upon the membranes and assist in healing.

        The complete outfit consists of the Generator, a nose-piece, a mouth-piece, pressure bulb, inhalant solution.

        Complete with all attachments as shown.  $18.00.




        Vacuum Glass Electrodes for High Frequency Violet Ray Application are made in two types.  Plain, or non-insulated, and insulated.  Insulated electrodes are used for Orificial treatments mostly, as they deliver a greater quantity of current at the desired locality.

        Master electrodes are made of the best grade of special glass, which will stand heavy usage without signs of deterioration.  The vacuum in Master electrodes is perfect.  The end of the electrodes are protected by metal caps, which insure greater life.  All electrodes are carefully tested and packed.

        Neon Red Ray Electrode consists of an Electrode which has been highly evacuated and filled to a definite pressure with a very rare gas called Neon.  The process of securing Neon is very complicated and expensive, therefore, commercial price of Neon is extremely high.  Neon has two salient properties, the faculty of readily conducting electric current and emanating an orange red light which has proven itself to possess decided healing properties.  This light can be only secured through the use of Neon gas.  When these properties are used in High Frequency Electrodes a great increased efficiency is noticeable in the treatment of certain conditions.  The most sensitive parts may be treated with Neon Electrodes without irritation and they are extremely beneficial to any pustulous or inflamed condition.

        Neon electrodes may be used with any Master Violet Ray machine.




        All regular Violet Ray Electrodes listed at $1.00 can be supplied at $3.00 each.  All regular Violet Ray Electrodes listed at $1.50 and $2.00 can be supplied in Neon Electrodes at $4.00 each.

        Pain or tenderness at any point along the spine signifies involvement of that corresponding organ.  Both the organ and the spine should be treated.

        By Violet Ray treatments these Spinal Nerve Centers can be stimulated to cause the parts and organs which are controlled by them to respond.

        High frequency application to the correct spinal region will restore an organ which has lost its natural tone or shows impaired activity. The normal state of the organ or part will be regained so that its duty can be properly carried out.




        The following are suggestions. In most instances the individual will develop their own technique in their own case.

        Violet Ray treatments need not be of long duration. Short treatments at frequent intervals are very effective. Always start with the weakest current possible. The initial discharge which occurs when you bring the electrode to the body in making contact should be avoided. Make contact with electrode quickly when beginning and finishing treatment. If metal object like hairpins, corset steels, chains, etc., cannot be avoided in the treatments they should be removed.


        There is no quackery or uncertainty about the Violet-Ray High-Frequency Current. It is a thorough cell massage, and a wonderful stimulant, and while it is by no means put forward as a cure-all, yet it is of the utmost aid in restoring to normal the physical condition impaired from almost any cause. The results obtained are universally beneficial and can never in any instance be harmful.


        The following are suggestions for the treatment of disease taken from cases where physicians or clinics have obtained excellent results. Not all cases will be cured through High-Frequency alone, but in every case it is a valuable adjunct to other treatment; in fact, many cases have been greatly benefitted where medical treatment has failed.
