MASSAGE VIBRATOR.

Application. filed June 25, 1925. Serial No. 3.9;446;

To all whom it may concern:

Be it known that we, J OHN MATCH and FRANK A. Nrrr, citizens of the United States residingat Oakland, in the county of Alameda; and State of California, have invented certain new and useful. Improve-c ments in Massage Vibrators, ofwhich thefollowing' is a. specification.

Our invention is a massage vibrator in.

which. aplurality of massaging and: vibrating buttons are mountedon' a drum which may be shifted or rolled over a persons body and; therefore cause a vibration with a slight massaging movement.

- Our invention is directed to a; manner of not only giving reciprocatory vibrations but to move the massaging buttons over the body with the movement of translation thereby combine the vibration with. the massaging effect.

The vibrator as awhole is constructed with an electric motor which has a pair of casings secured to the opposite ends and a spider. shaped device having a plurality of arms; with. buttonsv on the ends thereof are mounted onv eccentrics on the motor shaft so that the buttons are given a reciprocating motion, the stems supportingthe buttons operating through slots 111 the casing. The

' movement of translation or peripheral movement. is caused by a fixed pin engaging a slot in the spider and thereby forcing all the'arms or stems to have a somewhat circular" motion which, for the most remote buttons, will give an oval motion, so that the buttons will be drawn along a persons body when undergoing; atreatment.

Our invention willbe more readily understood from the following description and drawings, in which Figure 1 is a: longitudinal section of our vibrator taken on the line 1-1 of Figure 2 inv the direction of the arrows. I

Figure 2 is an end view of Figure 1 in the direction of the arrow with the end casing cap and handle removed. 7

Figure 3 is a detail section of Figure. 2 on the line 33 in the direction of thearrow.

Figure 4 is a diagrammatic view ofthe spider, the arms and the eccentric and: guiding slot to illustrate the, movement of the vibrating buttons.

The vibrator has a driving motor 1' in which the laminated fields 2 form one part of the periphery and the casings 3-and 4 are secured, onto each end of the motor tures 10- in the partition wall '11- of the easings 4. Nuts 12' threaded on the straight portion 13 of the angularly bent bolts? securethe casings 3? and 4 on: opposite ends of the motor.

The motor shaft 14 is journalled at 15- in; the-partition wall 11 and has secured toeach enda detachable eccentric block 16 secured in place by set screws 17, the eccentric por tion 18 being on the inner face. A spider 19 having a series of arms 20with reduced: stems 21 extending radially from; the-body of the spider is fitiiGClyOl'L the eccentric, the stems extend through slots 22 in the casing through grooves 23 which are for the: purpose of assembly. Buttons 24- are secured to the endsof the stems and are preferably dome shaped and form themassage elements.

The spider has a web portion 25 with a' I steel guide block 30 fits against the sides of the slot 26 and forms a bearing for thereciprocating motion of the web part 25 of the spider.

Referring to Figure 4 it will be, seen that the eccentric causes the-arms'tomove in and out in a radial; direction and on account of the pivoting and-sliding motion of the.- spider relative-to the fixed pin 27 the ends of the stems, or the buttons, are also given an oscillatory movement in somewhat of aperipheral direction. The combination of these movements causes any particular point of the buttons to travel in a circular or flat oval path. It willbe noted that the buttons on the side nearest the fixed pin have-a. substantially circular motion and that. thetwo extreme left and right buttons have a more elongated path and: that the. two upper or most remotebuttons have a more pronounced oval path. Therefore, a: person undergoing a massaging treatment may have the but tons give a vibratory motion or combine; this llU 'of the bent bolts i'.

with the smoothing or slight rubbing motion. It will be understood that the .vibrations are of small degree but are very rapid in accordance with the rotation of the motor and that the eccentric block 16 may be changed to either increase or decrease the vibration.

A pair of end caps and 36 are secured to the housings by means of nuts 37 engaging the outer ends of the straight portion 13 These caps are both substantially the same. A handle 38 is mounted at one end having a bolt 39 secured through the cap 35 and forming a swivel for the handle. The other handle 40 has a sleeve 41 secured thereto and an insulating block 42 secured thereto by screws 43, a neck 4% of the wooden handle l5 being secured by screws 46. The inner end A7 of the insulating block 42 is enlarged so as to bear against the inside face of the cap 36 and thereby allow the handle 40 to swivel.

The purpose of the swiveling handles is to allow the operator to hold the device in each hand and roll it slowly over a persons body so that they will be subjected to the vibration and the massage in this treatment.

The electrical connections to the motor are substantially as follows:

The electric leads 48 are carried on an insulated cable through the handle 40 and are divided, one terminal 49 being connected to a ring 50, whereas the other central ter minal 51 ends at a central button 52, these wires passing through suitable passages in the insulated block 4.2. A contact 53 supported on the spring arm 54 which is rigidly secured to a lug 55 fastened to the partition 11 carries the current from the ring to a lead 56 extending to the motor. A contact 57 on the spring arm 58, which is secured to a lug 59 connected to the partition 11 takes the current from the central button 52 to'the other terminal of the motor. It will thus be seen that this arrangement provicles sliding M contacts taking the current through the handle and the rotating casing and cap to the electric motor. Apertures 60 in the partition 11 and 61 in the caps 35 and 36 are for the purpose of ventilation and the small passage 62 is for the purpose of oiling the motor shaft.

The manner of use of our device will be obvious. The electric current will be switched on and off by a switch external to our vibrator and the whole device may be lightly rolled or moved over a persons body and they may thus be treated with both the vibratory and massaging movement at one and the same time. Although these movements are very slight they are so rapid as to have beneficial results, which are more marked than a straight reciprocatory vibra-' tion and than a straight movement of translation having a massaging effect.

Our invention may be materially changed, for instance by installing more or less vibratory elements and in changing the type of motion of such elements without departing from the'spirit of our invention.

Our invention is an improvement or an adaptation of the foot vibrator shown in our patent application Serial No. 34,008 filed June 1, 1925, and co-pending with this application.

Having described our invention, what we claim is 1. A massage vibrator comprising in combination a plurality of vibratory buttonlike elements, a drum shaped device in which said elements are mounted, handles by which said drum shaped device and the buttons may be rolled and means situated in said drum shaped device for operating the button-like elements.

2. A massage vibrator comprising in combination a cylindrical casing, an electric motor situated therein, an eccentric on the motor shaft, and a vibrating element having a series of buttons extending beyond the casing, and handles swiveled to the casing whereby the whole device may be rolled over a persons body.

3. A massage vibrator, as claimed in claim 2, in which a fixed guide element is secured to the casing and extends into a slot in the vibrating element.

4. A massage vibrator comprising in combination an electric motor, a cylindrical casing fixedly secured to the end thereof, an eccentric fixed to the shaft of the electric motor, a spider fitted on said eccentric and having a series of radial arms extending through slots in the casing, massage buttons secured to the ends of the arms and electric leads to and from the motor.

5. A massage vibrator, as claimed in claim at, having in addition aslot in the spider and a pin secured to the casing fitting within said .slot to force the buttons into a combined radially reciprocating and peripherally oscillating movement.

6. A massage vibrator, as claimed in claim l, having in addition a cap secured to the casing and a handle swivelly mounted on the cap.
