MASSAGE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 733,977, dated Jul 21, 1903.

Application filed March 30, 1903. Serial Nol50,283. (N0 model.)

To all whom it may concern:

Be it known that we, FRANCIS G. LAGER- STROM and ANDREW G. ANDERSON, citizens of the United States of America, residing at Salina, in the county of Saline and State of Kansas, have invented new and useful Improvements in Massage Apparatus, of'which the following is a specification.

The invention has special reference to that class of massage implements which have a movable member, such as a wheel or a cylinder or a ball or the like, adapted to be moved about on the body under pressure without causing any friction on the skin or body further than is caused by such pressure. It also has special reference to electrical massage instruments.

The general objects are toimprove and simplify theconstruction and use of such implements.

Special objects are to provide a massage implement having a movable member capable of movement in all directions, so as to be used in the circular motion; to provide an electrical implement of similar nature; to combine the parts, so as to have all the good effects of both the circular movement and elece tricity with the least possible exertion on the part of the masseur.

The invention consists of the novel combination, arrangement, and disposition of theparts, one of the preferred forms of the embodiment whereof is herein described and able member or ball, showing especially the} location of the pole-pieces on the surface of the ball and the method of securing the two parts of the ball together and of securing the battery inside the ball and of electrically connecting the poles of the battery with the polepieces in the surface of the ball.

Like letters refer to like parts throughout the several views.

A is the handle or fixed member.

Fig. 2 is a similar view with parts 1 B is the ball or movable member.

By a fixed member, as the term is used in this specification, we mean a member whose position with reference to the body is constant as it is moved about or whose position is quite immaterial, as it does not come in contact with the body. By a movable member we mean'a memberadapted to come in contact with the body, but which changes its position with reference to the body as it is moved about the body-that is to say, revolves 0n the body as a wheel or a cylinder or a ball.

The handle A has a socket consisting of the cups C and D, in which the ball B may rotate in all directions. The cup D is mounted on the set-screw E, which engages the lug F of the handle A and is locked in place by the jam-nut G.

The battery H is set in a suitable threaded metallic band I,which engages the internallythreaded metallic bands J and K, which are part of the hemispheres b and b, respectively, which form the ball B.

L L are contact-springs on the battery H,

insulated, P, from the threaded band I and adapted to come inLo'cont-act with the metallic contact-bands M M, which are embedded in the inner surface of the respective hemispheres b and 1). One pole of the battery is connected, N, to the band I and the other pole is connected, 0 O, to the contactsprings L L.

As indicated already, the ball B is hollow. The shell may be hard rubber or other suitable'insulating material. Embedded in the surface of the ball are the pole-pieces R R R, which are separated from each other by suitable ridges S S S of the insulating material. The said pole-pieces are connected to the battery as follows: One pole of the battery, through the wires 0 O, contact-springs L L, contact-bands M M, and wires 'm m m m, is connected to alternate pole-pieces, while the other-pole, through the Wires N, band I, bands J K, and wires '11 71 an, is connected to the other pole-pieces. The ball B may be opened by unscrewing either of the hemispheres b or b from the rim or band I of the battery, and the battery may be entirely removed from the ball by simply unscrewing the remaining hemisphere. The ball maybe removed from the handle by unscrewing the set-screw E. When the two hemispheres are screwed tightly together,the ball has a smooth surface, as indicated in the drawings, so that the ball may move in all directions in the socket of the handle. Although here shown as a friction-bearing, it is plain that any suitable bearing may be nsedsuch, for instance, as ball-bearings.

An implement of this kind capable of movement in all directions is especially adapted to massage by the circular movement. An instrument of this kind is especially effective in cases of constipation, as in such cases the patient can easily be his own masseur by lying on his back and passing the implement around in a circular motion over the abdomen, especially following around over the colon.

That which we claim as new, and desire to secure by Letters Patent, is.

1. In a massage apparatus, the combination of the ball having pole-pieces insulated from each other, and a source of electrical energy connected with the pole-pieces.

2. Inamassage apparatus, the combination of the ball and the socket therefor, the ball being capable of rotary motion in all directions and having pole-pieces, and a source of electrical energy connected with the polepieces.

3. In a massage apparatus, the combination of the ball and the handle, the ball being mounted in the handle and capable of movement in all directions, and having pole-pieces insulated from each other, and the source of electrical energy connected with the polepieces.

4. In a massage apparatus, the combination of the movable member and the fixed member, the movable member mounted on the fixed member and capable of rotary movement in all directions and having pole-pieces insulated from each other; and a source of electrical energy connected with the polepieces.

5. In a massage apparatus, the combination of the movable member having pole-pieces on the surface thereof insulated from each other, and a source of electrical energy within the movable member connected with the polepieces.

6. In a massage apparatus, the combination of the movable member having pole-pieces insulated from each other; the fixed member on which the movable member is mounted so as to be capable of rotary motion in all directions; and the source of electrical energy within the movable member connected with the pole-pieces.

7. In a massage apparatus, the combination of the ball and the socket therefor, the ball being capable of rotating in all directions and having pole-pieces insulated from each other; and a source of electrical energy within the ball connected with the pole-pieces. I

8. In a massage apparatus, the combination of the ball and the handle, the ball being mounted in the handle and capable of rotating in all directions and having pole-pieces; and a source of electrical energy within the ball connected to the pole-pieces.

9. In a massage apparatus, the combination of the movable member and the fixed member, the movable member being mounted on the fixed member and capable of motion in all directions and having pole-pieces in the surface thereot' insulated from each other; and a source of electrical energy within the movable member connected with the pole-pieces.

10. In a massage apparatus, the combination of the movable member having polepieces embedded in the surface thereof and insulated from each other, and a source of electrical energy within the movable member connected with the pole-pieces.

11. In a massage apparatus, the combination of the fixed member having a socket; the movable member having pole pieces embedded in the surface thereof insulated from each other, mounted in the socket, and capable of motion in all directions; and the battery within the movable member, the opposite poles of the battery being connected to the pole-pieces alternately.

12. In a massage apparatus, the combination of the fixed member having a socket and forming the handle; the movable hollow spherical member removably mounted in the socket, capable of motion in all directions, and

having pole-pieces embedded in the outer surface; and the battery removably held within the movable member, the opposite poles of the battery being electrically connected with the pole-pieces alternately.

13. In a massage apparatus, the combination of the fixed member having a socket and forming the handle; the hollow spherical movable member removably mounted in the socket, capable of rotary motion in alldirections, having pole-pieces insulated from each other embedded in the exterior surface thereof, and consisting of the two separable hemispheres; and the battery within the movable member, the opposite poles being connected with the pole-pieces alternately.

In testimony whereof we have hereunto affixed our signatures in" presence of two wit nesses.
