This is the fourth in a new series of posts on interesting, early applications of electricity, most of which are taken from the archives of the U.S. Patent Office.
J(osephus) C. Chambers, the patentee of the apparatus below, was the owner of Chambers' National Lightning Protection Company (Newport, Kentucky), and held a number of patents relating to lightning rods, electrical insulators, a telephone apparatus (1881), and a number of associated bits of techno. I'm not exactly sure what this device, below, did, except that it seems like a low-voltage quack-medical electric chair.
The first patent drawing, below, shows a view of the chair and at front, looking backwards towards the "ornamented" wooden cabinet that contained the guts of the machine, with the seat (which would have a metallic, conductive surface) removed. You would place your hands on the two capital "H" pads that seem to be just below the two drawers; your feet would go on the two "h" pads at bottom.
The drawing below references how the various swinging arms and such can be maneuvered to reach any part of the body. Mind you now the inventor doesn't actually state what this electrical treatment "does", only how you apply it and the technical stuff behind the machine. Also ir is not a solitary experience--there would be another person operating the controls on the top of the wooden case.
I wondered about the cup ("J"), and thought, well, maybe that's not what I think it might be for...but it is, waiting there to treat "the depending organ".

JOSEPHUS C. CHAMBERS, OP DETROIT, MICHIGAN.
ELECTRICAL MEDICAL APPARATUS.
SPECIFICATION forming part of Letters Patent No. 445,636, dated February 3, 1891.
Application filed April 21,1890, Serial So, 348,911, (So model,)
To all whom it may concern:
Be it known that I, Josephus 0. ChamBees, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Electrical Medical Apparatus, of which the following is a specification. This invention relates to electrical medical appliances, and has for its object the production of a device by means of which electrical currents, either continuous or interrupted, and either the current of low electromotive force of the primary or direct current or those of higher electro-motive force or induced or secondary current of different strengths, may be employed under the supervision of one skilled in employing electricity medically. These appliances are arranged in a convenient and compact form, and for use are gathered into and upon a box or cabinet of ornamental appearance, which serves as a ease, within which are stored the cells of a galvanic battery sufficient in number to produce the requisite quantity of electric current. On the top of the case I arrange a switch-board, and on the front side is a standard supporting the various arms and contactpieces used in applying the current locally to the patient.
Accompanying the cabinet and forming a part of the apparatus is a chair or seat upon which the patient sits while undergoing treatment. This may be a simple stool having a metallic seat or it may be a chair of a more complex form. The general organization of my apparatus is shown in the accompanying figures, in •which— Figure 1 represents the front of the cabinet...
On the front of the cabinet B is a vertical standard A. Upon the standard A are a number of arms held adj nstably to the standard by split rings and binding-screws, (a detail is shown in Fig. 11,) the ring in each case being insulated by an interior lining X of insulating material. To the ring G are attached two horizontal arms IP IP, arranged to support two hand-rests II IF, each hand-rest being provided on its upper surface with a cushion of sponge or other similar material of such a nature that the electric current pass ing to the patient is diffused by the moist cushion over the part under treatment. G' supports a curved arm, bearing a cross-arm and adjustable cushions arranged and adapted for local treatment of the back, a detail of the cross-arm Is showing the adjustable contact-cushions I' P, and the spring connectingjoint i between the cross-arm P and the arm I is shown in Fig, 8.
The arm I turns on the shank of the thumb- nut holding it to the ring G', and is supported at any desired inclination by means of the brace i' and ring G3. A sliding joint i, distended by an inclosed spring, connects the cross-arm P to the curved arm I, and causes So the cushions I' P to adjust themselves with an even pressure on uneven surfaces of the body. From the ring G3 rises the arm J, carrying the cross-arm J' J3, one of which supports a cup j and the other an electric light L. The cup j is supported on an insulating-handle/.
Across the bottom of the standard is a cross-rod K, supporting the foot-rests h li, for furnishing an electrical contact to the under go surface of the feet.
Each of the contact-pieces is furnished with suitable means for attaching a current-wire to it. The stool or seat is also furnished with a suitable means for being placed in the cir- 95 cuit, as the binding-post 30, and thus when wired, the patient sitting upon the stool and having the part under treatment in contact with the appropriate cushion or contact-piece receives the current through the body. Of course, when preferable, the stool may be thrown out of circuit and the circuit may be completed through two of the contact-pieces and that portions of the body or limbs reaching between them. 'The method of using the various parts, except the cup j, is obvious from the drawings, and it Js obvious that the operator can arrange the condueting-wires so that the current of electricity will pass through only the part of the body which it is desired to treat.
The cup j is to be used in treating depending portions of the body. It is a cup of nonconducting material, preferably soft rubber, into the bottom of which is a terminal/, covered by a button j3, which protects the body from actual contact with the terminal, while it permits it to receive the current through the contained water or fluids with which the cup is partly filled when in use.
In order that I may use the kind of current applicable to any particular case, and may regulate the rapidity of the successive impulses of the current, I employ the multiple induction-coil shown in detail in Figs, 5, 6, and 7. The wiring of the apparatus is concealed within the cabinet, and I have indicated only that which is peculiar to my multiple induction-coil, inasmuch as the wiring necessary for the switch-board will at once be evident when the use of the various contact-posts is declared. The switch-board is in part shown on Fig. 2 and in part indicated on Fig. 4. That shown on Fig. 2 is used for the purpose of regulating the strength and controlling the polarity of the current and the rapidity of the successive impulses employed. The switch-board shown on Fig. 4 is used to enable me to employ a current of such strength, whether primary or first, second, third, or fourth induced or secondary current, as I may desire, or as may be deemed most applicable to the case under treatment.
The induction-coil is shown in Fig. 4, and it consists of a primary and four secondary coils, one end of each of the latter being connected with the primary coil to regulate or increase the force of the current passing therethrough.
On the switch-board shown at Fig. 2 the contact-posts Q q q, &c,, arranged in a circle,
50 are the same as those ordinarily used to place in circuit one or more of the several cells of the battery, while R r switch into the circuit the coil and Wagner hammer. R r' r2 are respectively used in giving a plain galvanic current, a primary current through the coil, and a first-induced current. S S' change the polarity or direction of the current, tf switches . the motor 7 into the circuit, while the rapidity of the successive impulses is regulated by the posts T' T3 T3, which are wired, respectively, to the contact-springs t t'-t*.
The rapidity of the successive impulses is regulated by the motor 7. (The details are shown in Figs. 5, G, and 7.) This is a motor in which the rapidly-revolving armature 8, through the worm and wheel 9, produces a comparatively slow motion of the worm-wheel
The current passes through the wheel 9 and passes oat through the ends of the teeth 10 or thimigh the pins 11, or through the pins 70 12 to the proper contact-spring 11't2, passing to that one of the contact-springs which is in circuit through the posts T', Ta, or T8, thus giving at each revolution of the worm-wheel a number of impulses corresponding to the 75 number of times the current has been interrupted. All these variations in the current are or may be carried through the second switch-board, Fig. 4, so that they may be employed with an induced current of increased 80 or diminished strength.
In Fig. 12 the method of applying the contact-pieces to a person under treatment is shown.
In Fig. 13 is shown a modified form in which 85 the external wiring from binding-posts 15 20 to the various arms, carrying contact-pieces, is omitted. In this modified form there are two upright standards a a', connecting directly to the binding-posts 15 20, and on these 90 posts a a' the arms are mounted directly by means of the split rings g g' gz, &o, In this form, however, the interior insulating-ring X is omitted, and the metallic ring presses directly upon the metallic standard and becomes a part of the conductor. Another modification employed with this form is to make all the connections g g' g*, &c., universal joints. The joints G' G8 in the first form described are also universal.
While I have thus shown standards and arms adapted to reach nearly every part of the body, I do not wish to be limited to either the number or form of any of those shown, the object of the invention being to produce 105 an apparatus in which the curative powers of electricity may be easily and readily applied, and in which, especially, I may employ the induced electricity of varying strength, as I have explained. no Having thus described my invention, what I claim as novel, and desire secured to meby Letters Patent, is—•
