1 Claim.

The present invention relates to electrical massaging devices and has for an object to provide a small device adapted to be held in the hand for massaging the body, in which self-contained electrical units are housed and protected, while controllable easily and conveniently from the exterior of the device.

Another object of the invention resides in providing an improved electrical massaging device having an irregular contour for physically stimulating the body with which it comes in contact and provided on such irregular surface with numerous electrodes, both negative and positive, for further stimulating the body by the passage therethrough of numerous currents of electricity.

A further object of the invention is to provide an improved electrical massaging device in which the current intensity may be nicely regulated and in which the control units are exposed for easy manipulation.

With the foregoing and other objects in view, the invention will be more fully described hereinafter and more fully pointed out in the appended claims.

Fig. 12 is a diagrammatic view showing the complete circuit arrangement, and 50 Fig. 13 is a perspective view of the improved bag employed.

Referring more particularly to the drawings, the device is preferably composed of, and housed in, a casing of insulating material including the three sections 15, 16 and 17.

The applicator section 17 is preferably irregular or corrugated as to external contour, the same being preferably concaved longitudinally as shown in Fig. 2 and convexed transversely or laterally as shown in Fig. 4 and being provided with numerous positive and negativeelectrodes or wires 19 and 20 exposed on the rubbing or applicator surface which comes in contact with the body or epidermis. The roughened surface will physically stimulate the body when the device is rubbed thereover, and moreover an electrical stimulation will be had by reason of the flow of current from the positive to the negative electrodes or wires which are threaded through spaced openings 21 in the applicator section 17.

The method of threading the wires or electrodes 19 and 20 through the applicator section 17 is indicated in Fig. 5. As shown in Fig. 7, the intermediate section 16 is secured to the applicator section 17 by the use of screws or other fastenings 22.

As illustrated in Fig. 5, screws or other fastenings 23 are employed to hold the top section 15 to the intermediate section 16.

The top and intermediate sections 15 and 16, as appears in Fig. 5, are cored out mutually to provide battery chambers 24 and 25 for dry batteries and an intermediate chamber 27 for an induction coil. The dry batteries are shown at 28 and 29 in Fig. 'l; and the induction coil at 30. By removing the fastenings 23, the top section 15 may be lifted off the intermediate section 16 to expose the batteries and coil for renewal or repair.

As shown in Fig. 8, spring contacts 31 and 32 for the batteries are carried by the intermediate section 16 and permit of the ready removal of the battery when exhausted and the replacement of a fresh battery.

As shown in Figs. 6 and 9, spring contacts 33 and 34 are carried by the lower or applicator section 17 for making contact with leads carried by the intermediate section 16 as further explained in connection with the diagram in Fig. 12. The knob or operating button 35 of the control switch is shown as projecting from the housing or casing for convenient manipulation. In like manner the rotary control button 36 for the various sections of the secondary coil is also shown projecting from the housing or casing for easy and convenient operation.

Referring more particularly to Fig. 11, 37 designates the core of the induction coil 30, and 38 the primary winding thereof, which is connected at one end to the vibrator 39 adapted to have make and break contact with the stationary contact 4G. The other end of the primary winding 38 is connected by lead to a contact strip 41, which is disposed in spaced and parallel relation with a companion contact strip 42 connected with the spring contact 31 at the negative side of battery 29. A forked contact strip 32 is disposed in spaced relation to the strip 42 and connected by leads 33 with the spring contact 31 of the opposite battery 28, negative side. A second forked contact strip 45 is connected by a lead 46 with the spring contact 32 to the positive side of battery 29.

The positive side of the opposite battery 28 is connected to a contact strip 47. These various contact strips are adapted to be connected or closed in a definite sequence by means of contact sleeves 48, 49 and 50 carried by an insulating switch rod 51 connected to the external button 35 and being slidably mounted in the intermediate casing section 16, as shown in Fig. 5. The various contact strips referred to are also carried by the intermediate section 16 as also appears from Fig. 5, these parts being located in a groove 52 provided in such section 16. The switch rod 15 is normally projected outwardly to the position indicated in 11 by means of a coil spring 53 disposed behind the rod 51 in a socket 54 of the intermediate section The position of the parts shown in Fig. 11 shows an open circ it at the contact strips 41 and By pushing in upon the button 35 the circuit may be closed as hereinafter described and by rotating the button 35 through a half turn or a 189 the batteries and 29 may be placed either in parallel or series arrangement with the primary coil 38.

Referring more particularly to Fig. 12, the secondary winding of the induction coil is indicated at 55, and at 56, 57, 58, 59 and 60 are indicated leads talcen off from the secondary coil 55 at various points and leading to stops or buttons indicated 1, 2, 3 and 4. One end of the secondary coil 55 is connected by the lead 56 with the spring contact 33, while the other end of the coil is connected by the lead 61 with stop or button indicated 5.

An arm 62, operable by the rotary control button 36 is adapted to sweep over the stops 1, 2, 3, l and 5 for the purpose of cutting in and out various sections of the secondary coil 55 and thereby controlling the intensity of the induced. current. A spring contact finger 63 bears at all times upon the hub of the arm 62 and is connected by a lead 6-1 with the spring contact 34 which leads to the electrodes 19. The electrodes 19 are all connected together by a bus wire while a bus wire 66 connects all of the other electrodes 20 together. The lines of the electrodes 19 will preferably alternate ith the lines of the electrodes 20 so that the surface of the applicator member will be covered by numerous electrodes of positive and negative sign adapted to transmit nu.- merous currents over a relatively wide area.

Referring now to Fig. 67 designates a fabric or other bag so shaped as to envelope the applicator section 17 or all of the sections if desired. This bag, particularly who wet, will afford a better distribution of the cu1rent and eliminate the shock, giving only an agreeable passage of the current through the epidermis.

In the operation of the device, viewing Fig. 11, by pressing in upon the button the contact sleeve 28 may be made to bridge the contact strips 41 and 42 in which case the batteries 28 and 29 are placed in shunt or parallel with the primary winding 38 of the induction coil 30. From the battery 29 the current flows through contact 32, contact strip 45, sleeve 50, contact strip 47, vibrator contact 40, vibrator arm 39, primary winding 38, contact strip 41, sleeve 48, contact strip 42 and back through the spring contact 31 to battery 29.

Current from the opposite battery 28 flows out through positive contact 32, vibrator contact 40, vibrator arm 39, primary winding 38, contact strip 41, sleeve 48, sleeve extension 48, contact strip 43, and back to the negative side of battery 28 by lead 44.

As soon as the primary winding 38 is energized, the core 37 will become magnetized, attracting the armature 39, thus breaking contact at 40 and interrupting the primary circuit. The core 37 then becoming demagnetized, the armature 39 will spring back into contact with the contact point 40, thus again closing the circuit.

In this Way a rapidly interrupted primwy circuit will be created, inducing in the secondary winding 55 a high tension current.

If the switch rod 51 is rotated through 180 degrees. it will assume the position shown in Fig. 12, the half extension sleeve 48 and 50 being thus removed to the opposite side away from the contact strip, and the half extension sleeve 49 being moved over toward the contact strip with the effect that, when the rod 51 is pushed in, the two batteries 28 and 29 will be placed in series with the primary winding 38 as follows: battery 29, lead l6, contact strip 45, sleeve 49, contact strip 43, lead 44, battery 28, vibrator 39, 40, primary winding 38, contact strip 41, sleeve 48, contact strip 42, back to battery 29. In this way two steps of regulations are given with respect to the primary circuit. By the manipulation of the rotary control button 36, the intensity of the secondary circuit may be regulated as heretofore described. The bag 6'7 may or may not be used, but when used it will lessen the shock and create a more uniform distribution of the current and current effects.

Having thus described the invention, what is claimed as new is:

As an article of manufacture, an electrical massaging device comprising three vertical sections, one of said outer sections having a. substantially rigid and corrugated surface for massaging purposes, said surface being concave in contour longitudinally and convex in contour transversely, and said corrugated surface carrying spaced rows of positive and negative electrodes in staggered pattern for application of electric current to the massaged body, batteries and an induction coil carried by the center and the upper sections, means for removably connecting said sections together, a switch for regulating the intensity of the current to the electrodes, and a second switch comprising a reciproeating rod biased to an open position and having a plurality of sleeves thereon with partial sleeve extensions, said sleeves and one of said extensions contacting with spaced contacts to connect said batteries to said coil in parallel, said rod being also capable of rotation on its own axis to disconnect said ex ision and to connect said remaining sleeve extensions to said spaced contacts and thereby connect said batteries to said coil in series.
