the following is a specification.

' The most convenient form of apparatus to.

My inventlon relates to-electric therapeutic devicesandcomprises an improved portable apparatus adapted to be carried in and manipulated by one hand of the operator, and which when placed in contact with the head or any part of the operators body will put the same in circuit with the terminals of a mechanical generator of electricity mounted on the apparatus so that any current generated is sent through the body.

be so equipped is a hair brush having bristles of metal or other electrically conductive material.

gearing driven by the hand that holds the brush.

The best form of apparatus at present known to me, together with certain modifications thereof, are illustrated in the accompanying four sheets of drawings in which:

Figure 1 is a back view of a hair brush constructed in accordance with my invention. Fig. 2 is a side view of the same. Fig. 3 is an enlarged back view with the generator casing removed. Fig. 4 is a side view of the same with parts shown in section; Fig. 5 is an enlarged detail of the post. supporting the spring contact for the magneto, showing its connections in section. Fig. 6 is an enlarged detail of spring contact for the magneto, the armature and connections, parts being broken away. Figs. 7 and 8 show modified body contact making devices. Fig. 9 shows a modification in which a spring motor is employed, and

Fig. 10 shows another form of hand operated generatondriving apparatus.

Throughout theadrawings like reference characters indicate like parts.

The drawings show a hair brush composed of metallic bristles 1, 1, and an ordinary back and handle 2, made of wood, cut away at '55 to receive the electric generating mechanism.

The. mechanical generator is preferably driven by pawl and ratchet 3 is a front plate of metal running along back and handle 2. A back plate 4 may be placed on the handle and connected to front plate 3 by metal rivets 5, 5, or other convenient means.

6 is a holding sheet of leather or 'other suitable non-conducting material in which the bristles 1, 1, are set. place by the surrounding undercut frame 7 or similar device.

8 is a plate of metal with which all bristles 1, 1, are in electrical connection.

This is held 9 is a sheet of insulating material between 8 and 3.

10 is a casing for the current generator which in the preferred form comprises a fiat, crescent shaped field magnet 11, and a two pole armature 12 mounted on shaft 13 which carries driving pinion 14. The shaft 13 is journaled at one end in front plate 3,

and at the other end in skeleton housing plate 15. This housing 15 is supported on two posts 16, (but one of which shows in Figs. 4 and 5, the other being behind it) but insulated therefrom by thimbles 17, said thimbles being held on the reduced and threaded end of the posts by nuts 18.

One post 16 has a projecting arm 56 on which is mounted the bifurcated spring con- I tact piece 9, one branch, A, of which bears on the contact ring 20 (see Fig. 6) carried on an armature shaft 13, and the other branch B, makes intermittent contact with the short circuiting arms 21, 21, extending from armature shaft 13. The contact ring 20 and thearniature coils 57 are insulated from shaft 13 by insulating sleeve 24:, or equivalent device, and one terminal of the coils, as 22, is connected to ring 20 while the other terminal, as 23, is connected to shaft 13. I

In the preferred form of generator driving gear shown in Figs. 1 to 4, the gear wheel 25 meshing with pinion 14 on the armature shaft 13 is mounted on shaft'26 on the other end of which is inion 27 meshing with gear28 mounte on shaft 29. Loosely mounted on the same shaft is pinion 32 rigidly connected to ratchet wheel '31.

35. Preferably this lever 34 has a cutaway l Ian portion 58 through which shaft 26 extends and cooperates therewith to act as a stop for limiting the lever vibrations so that the toothed sector will never run out of mesh with pinion'32. The other end of lever 34 has a thumb piece 36 located in a position to be conveniently pressed by the thumb of the hand which grasps the brush handle. 37 is a spring normally forcing the lever in a direction opposite to that in which it would be. driven by thumb pressure and to cause the ratchet wheel 31 to slip under the pawl 30.

38, 38, are governor weights pivoted at 39, 39, to a disk 59 on shaft 13, and adapted to strike the brake spring 40, shown in Fig. 5 andin dotted lines in Fig. 4, which is adjusted by turning cam piece 41 rigid on shaft 42. 42 cagriesadjusting disk 43, shown in Figs.

44 is a tapped thimble set in the brush face and in electrical contact with plate 8. A series of threaded spindles 45 are adapted to screw into this thimbleand at their other ends carry various forms of contact devices, such as a flat felt covered disk 46, or a spherical felt covered button 47.

In operation of this form of my invention the brush is held by the handle with the thumb of the operator on thumb piece 36 of lever 34. If, while the brush is being used. in the ordinary manner, the metallic bristles being in contact with the scalp and the operatorshand making contact with plates- 3 and 4, the lever'34 is vibrated by the alternating pressure of the operators thumb and sprlng 37, continuous rotation will be given the magneto armature by the pawl and ratchet mechanism and multiplying gearing above described. As the short circuiting arms 21, 21, strike the branch B ofthe spring contact 19 the armature coils are short circuited and a current of considerable volume is created. Each time this short circuit is .broken a counter, induced current is generated in the armature coils, and shunted through the body of the operator from head to hand.

By adjusting thebrake s ring 40 toward or from the armature sha t, the governor weights 38, 38', strike it with more or less force and by so impeding the-rotation of the shaft, more or less, regulate the speed at which it will be driven by ordinary thumb pressure on lever 34.

By inserting one of the spindles 45 in thimble 44, and Wetting the disk or button at the end of it, an agreeable contact with the forehead or other portion of the body can be substituted for that afforded by bristles 1, 1,

In the modification shown in Fig. 9, l have shown a spring motor 48 geared to the magneto. This motor can be wound up by a The outer end of this shaft key engaging the spring arbor 49, and will run the magneto forlO or 15 minutes.

In Fig. 10, I have shown a different form of manually operated mechanism. The shorter lever 54 is connected by link 53 to lever 50 pivoted to the handle at 51. A spring 52 normally forces lever 50 awa from the handle, and when it is pulled bac by the closing of the operators hand, the generator is set in motion as before.

The advantages of my invention com rise the stimulating and curative effect 0 the electric currentsent through the operators body, the large volume of current generated by a neat and compact apparatus, and the avoidance of cumbersome batteries.

Having, therefore, described my invention, I claim 1. A brush having bristles composed of electrically conductive material, provided with a' rotary generator, of electricity connected, to said bristles, and means for rotating said generator adapted to be set in motion by the hand of the operator holding 3.
