EDGAR CHELLIS, OF ERIE, PENNSYLVANIA.
THERAPEUTIC ELECTRIC-CURRENT GENERATOR.
SPECIFICATION forming part of Letters Patent No. 584,853, dated June 22, 1897.
Application filed May 5, 1897. Serial No. 685,229. (No model.)
To all whom, it may concern:
Be it known that I, EDGAR IV. CHELLIs, of Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Therapeutic Electric- Ourrent Generators; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.
This invention has for its object to produce a generator of electric currents to be used for therapeutic and other purposes and which may be carried about conveniently in the pocket or on the person after the manner of a watch or locket and the current applied to the body through the means of conductors or electrodes to be worn on the person and adjusted as needed, to which ends the invention consists, primarily, in a spring-driven generator mounted in a flat casing, with means for conveniently rewinding the motor-spring after the manner of a watch; and, further, the illvention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.
Referring to the accompanying drawings, Figure 1 is a side elevation with the cover removed and the contact-spring shown broken away from its support and binding-post,which latter passes through the cover. Fig. 2 is a sectional view taken on the line 2 2, Fig. 1.
Like letters of reference in both figures indicate the same parts.
In carrying my invention into practice I provide a casing, preferably cylindrical, as shown, and relatively flat lengthwise of the cylinder, approaching in conformation the conformation of an ordinary watch, and preferably of a size adapted to be worn in the vest pocket and having at one side thereof a winding post and stem with a guard-ring, thereby simulating even more closely the appearance of a watch.
In the accompanying drawings the letter A indicates the casing; 13, the post; 0, the winding-stem, and D the guard-ring.
One side of the casing is preferably made in the form of a cover E, and, if desired, either the cover or the cover and the opposite side of the cover or the entire casing may be made of insulating material, such as rubber, but I prefer that the whole casing should be of metal and ornamented to suit the taste of the wearer.
Within the casing, and preferably at one side of a plane taken transversely through the cylinder portion of the casing, I preferably locate a spring-motor or train of gears E, terminating at one end of the train in a springdrum F and at the opposite end in a pinion Gr, mounted on a shaft located centrally of the casing and adapted to support an armature of an electric generator.
It will be understood, of course, that the particular form of spring-motor and train of gearing may be varied in any ordinary motor provided for this purpose, but I prefer in every instance to provide a means for rewinding the motor without arresting the movement of the generatorsuch, for instance, as the windingwheel ll, meshing with the drum and a pinion I on the windingstem C.
There it is found desirable to regulate the speed of the motor and to prevent the same from racing, a butterfly-wheel may be located at an appropriate point in the train of gearing, and any ordinary friction retarder or brake, such as the wedge K, may be made to engage any of the wheels. Said brake K, in the form shown, is adapted to be made by means of a block 7t, working in a slot in the casing to engage the periphery of the springdrum, as shown in Fig. 1.
In the opposite side of the casing I mount field-magnets, preferably two in number, as shown, and lettered L, although it will be understood that the number of field-magnets maybe varied or any of the well-known styles employed without departing from the spirit of my invention. As shown, these field-magnets are rectangular in cross-section and have their poles somewhat tapered to concentrate the fields of force, and the armature M,mounted on the shaft N, is relatively flat in crosssection and is adapted to receive the coils 0 between its field-pieces, one terminal of said coils being connected to the armature itself and the other terminal being connected to an insulated pin or post P, projecting axially from the shaft N. The contact-spring Q on the casing bears upon the pest P and is insulated from the casing and connected with the terminal binding-post q in the well-known manner. The opposite terminal or bindingpost (1 is connected directly with the casing. The current generated in the coils of the armature by the rotation of the same is thus caused to pass from said coils through the post I? on the one hand and through the gearing and frame of the casing on the other hand, from whence it is led off by wires connected to the binding-posts to the electrodes on the body of the wearer or to be utilized for other therapeutic purposes.
llavin g thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a therapeutic magneto-generator, the combination with a casing, of a spring-motor located in one side of said casing, with means forrewinding said motor, and field-0fforce magnets, and an armature located in the opposite side of said casing, with connections between said armature and motor, with terminals for leading off the current from the said armature; substantially as described.
2. In a therapeutic magneto-gencrater, the combination with the cylindrical casing adapted to be carried in the pocket of the wearer, a spring-motor train located in said casing, and cylindrical field-of-force magnets extending around the interior of said casing, of an armature connected with said motortrain and rotating in the field of force of said magnets, and terminals for leading off curand motor-train, and terminals for leading off the current from said generator; substantially described.
at. In a therapeutic ina-gneto-generator, the combination with the cylindrical casing havin g a removable cover, winding post and stem, of a spring-motor train located in one side oi. said casing and adapted to be rewound from said stem, cylindrical tield-of-lorce magnets located within said casing at one side of the motor-train and an armature rota-ting within said field-of-force magnets and driven by the motor-train.
5. In atherapeutic magneto-generator, the combination with the ilat cylindrical casing, and spring-motor train located therein, of the cylindrieally-arranged field-o'f-t'orce magnets extending around, within said casing, and the relatively flat armature rotating within said. field-of-foree magnets, and driven by the motor-train; substantially described.
