ELECTROTHERAPEUTIC APPARATUS.

SPECIFICATION forming part of Letters Patent No. 550,688, dated December 3, 1895.

Application filed April 1, 1895. Serial No. 543,969. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES PALMLEAF, a citizen of theUnited States,residin g at Seattle, in the county of King and State of ashington, have invented certain new and useful Improvements in Electric Therapeutic Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in electric therapeutic apparatus, the object being to provide a simple and compact apparatus which can be readily removed from place to place and from which can be derived a current of varying intensity.

Figure l is a plan view of an apparatus e1nbodying my improvements, showing the same arranged within a case or receptacle specially designed to receive it. Fig. 2 is a vertical sectional view of said case. Fig. 3 is a side elevation thereof. Fig. 4 is a detail end elevation of the apparatus. Fig. 5 is a side elevation of the same. Fig. 6 illustrates the removable core. Figs. 7 to 10 are detail views of electrodes.

In the drawings, wherein like letters of reference denote corresponding parts in the several views, A designates as a whole a table or stand which I have constructed for the special purpose of holding and protecting my improved apparatus. This table or stand is supported on legs or standards A and is provided with a swinging cover or top 0. In Figs. 1 and 3 this top 0 is shown as swung up to expose the apparatus or to permit of its ren1 oval from the table but normally such cover extends entirely over the table, as shown in Fig. 2, and, besides protecting the apparatus, permits of the table being used as an ordinary stand. The top 0 is connected with the body of the table by means of side bars or arms 0, which are provided at their free ends with laterally-projecting pins 0, that extend through slots a, formed in the sides of the table.

The interior of the table or stand is divided into three parallel compartments by means of partitions A and the central compartment is specially formed to receive the apparatus, the other side compartments serving to hold the electrodes, removable cores, and other detachable parts of the apparatus, or for any other purpose. The rear portion of said central compartment of the table is made of greater depth than the other portions thereof, and there is thus formed a downwardly-extending socket or receptacle A in which may be fitted the cell or battery D of the apparatus. In the forward and relatively shallower part of said central compartment is adapted to be fitted the main induction-coil E, which is connected with the elements of the cell D by suitable conductors D.

The induction-coil E is mounted and supported on a base-plate E by means of suitable end pieces or supports E The conductors D, leading from the cell or battery D, are designed to have their free ends inserted in sockets in the upper ends of posts D One end of the primary winding of the coil E is connected with a post F to which the spring-arm F is connected, and on an arm extending out from the adjacent post D is mounted a pivoted finger f, adapted to contact with said spring'arm F. The post F is electrically connected with a socket G in the base-plate E. The other end of the primary winding is electrically connected with a series of sockets H H II, and H in the base plate and with the post D at the right-hand end of the coil. One end of the secondary winding of the coil is connected with a socket G in the base-plate and the other end of such winding is connected with the sockets H H 11, and H.

The sockets in the base-plate are designed to receive plugs or pins carried at one end of flexible distributing conductors I, through which the current can be transmitted from the coil to any desired portion of the body.

The number of sockets in the base-plate, the connecting thereof with the various windings of the coil, and the number of the latter may be varied from that shown, as I make no claim herein for such features of the apparatus, my improvements being adapted for use with various styles of coils, 850.

Although in many instances it is unnecessary to remove the induction-coil from the box or stand when the apparatus is in use, yet in certain cases it is desirable to move it from place to place and secure it at points and in positions which would be impossible to do were it retained within the table. I have therefore provided the base-plate E, on which the said coil is mounted, as heretofore described, with an adjustable clamp, by which it can be quickly and securely fastened to the projecting edge of a table, mantel-shelf, or similar article.

The stationary portion of the clamp, which may be formed in a single casting, consists of two substantially parallel arms g g, which are connected by an arm or bar 9 from which extends a web or plate 9 This plate g extends out from the bar g on the opposite side thereof from the aforesaid arms 9 g, and is securely fastened to the base plate E by screws or other suitable fastening means. The free end of the arm g is enlarged to form the head G which constitutes the stationary jaw of the clamp, and the opposing movable head G of the clamp is carried by a threaded pin g, working in a threaded passage in the arm g, and provided at its outer end with a thumb-piece g. It will thus be seen that the base-plate E and parts thereon can be quickly secured in position or removed for the purpose of transportation.

The core of the in duction-coil is preferably made hollow, and I have provided an auxiliary core which is adapted to be inserted therein to control and regulate the intensity of the current. This auxiliary core, which is shown in Fig. 6, consists of a cylindrical shell, in which are formed a series of perforations II". These perforations are arranged in the form of a spiral extending longitudinally of the core piece and provide a series of projections, which as the core is inserted into the coil tend to hold the same, so that its position with relation to the coil is readily regulated.

To the outer ends of the flexible distributing-conductors I are secured electrodes, by which the current is applied as desired. The electrodes may be of various forms, according to the special treatment desired. In Figs. '7 to 10 I have illustrated four forms, each possessing certain advantages for the treatment of certain cases.

The electrode illustrated in Fig. 7 consists of a spring-metal clamp, the ends of which may be clamped over the edge or rim of a metal basin and a current of electricity thereby caused to pass through water placed therein.

In Fig. 8 I have shown an electrode which is adapted to serve as a sponge-holder. It consists of a handle J of any suitable nonconducting material and an open ring or sponge-holder J which may be made hollow or tubular, if desired, to reduce the weight thereof. The conductor I extends into the handle J and is connected to one end of a shank or pin, by which the handle and body of the holder are connected and through which the current is conducted to the holder J In Fig. 9 the electrode is made in the form of a brush, while in Fig. 10 it is made as a belt adapted to be secured about a persons body and provided on its inner face with a series of aluminum plates or disks L, which are electrically connected together and to the conductor I.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

1. In an electric therapeutic apparatus, the combination with an induction 'coil having a hollow or tubular core, of an auxiliary core provided with a series of spirally arranged perforations, substantially as set forth.

2. In an electric therapeutic apparatus, an electrode consisting of a handle of non conducting material, a ring like member of conducting material adapted to hold a sponge, and a pin of conducting material connecting said ring and handle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
