MASSAGE MACHINE.

Application fled July 11,

This invention relates to a massa e machine for massaging, rubbing or mampulating the seal of the human head, of the general type s own and disclosed in my copending application, Serial No. 136,421, filed September 20, 1926.

Medical authorities contend that the dis ease of baldness is to a lar e extent'caused by the wearing of hats wlth tight bands. These tight hat bands, so universall worn by men, cause a restriction of blo circulation to the top of the scalp. The blood tissues at the top of the head are starved for nourishment. V

The principal object of the present invention is to provide means for gri ping the seal .around the entire hat ban area of the head, and to produce a vigorous massage of these parts so as to counteract the ill effect of tight hat bands.

This result is partially accomplished by the device as shown in my co-pending application Serial N 0. 136,421, mentioned above, which discloses massaging elements adapted to grip the sides of the head.

In my present invention described herein,

I grip the entire hat band area more completely by providing a plurality of applicatory elements or pads spaced in a circle around the head. I drive thesepads in reciprocating straight line motions at an angle of approximately degrees from the Vertical. In this way the entire scalp is lifted and vigorously massaged, and the effect produced is felt far more keenly than when only a part of the area is worked on at a time. A decided lifting effect is produced, not only on the entire scalp, but on the facial muscles as well. By gripping and operating the entire hat band area at one setting of the machine, not only is the labor and time required for a treatment materially reduced, but a vastly superior effect is obtained by the vigorous working of all parts of the scalp simultaneously.

Another feature of the invention resides in the provision of suitable guard means for preventing hair from being caught or entangled in the working parts of the driving mechanism, as well as preventing materials used on the hair during the massaging treatment from entering and affecting the mecha- Another object of this invention is to so 1m.

and associated mechanism, so as to rovide a massage device in which the weig t of the machine is substantially balanced when placed in operative position on the head.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims:

Fig. 1 is a plan view looking down upon the machine. Fig. 2 is a front elevation of the machine showing it applied to the scalp and hav1n a portion thereof shown in crosssection. ig. 3 is an end elevation showing the machine .applied to the human scalp. Fig. 4 1s a erspective view of the reciproeating mem er. Fig. 5 is a sectional view taken on the line 5-5 of Fig. 9. Fig. 6 is a sectional view taken on the line 6-6 of Fig. 2. Fig. 7 is a section taken on the line 7-7 of Fig. 2. Fig. 8 is a section taken on the line 88 of Fig. 2. Fig. 9 is a diagrammatic illustration showing the position of the massagin elements with respect to each other andt eir line of movement.

In the drawings there is shown a massaging machlne ormechanism and, for the purpose of illustration, an electric motor 10 is employed for driving means. This motor is shown mounted on the central portion of a stationary housing 11, the ends of said housing extending at an angle to each other, as best shown in Fig. 2. I find an angle of approximately 90 degrees to give the best results. Mounted in said housing, and extending transversely of the central portion thereof there is a shaft or spindle 12, in the present instance motor driven, having one end connected with the motor 10 and its other end extending into and keyed to the worm 13, said worm being provided with an extension bearing 14, extending into a bearing recess formed in the housing.

Positioned on each side of the worm 13 and extending into the housing 11, there are worm gears 15 adapted to 'mesh therewith and be rotated by the action of the motor. Each of the gears 15 is secured to a shaft 16 having its upper end mounted in the bearing 17 and its lower end mounted in a suitable bearing secured inv the lower surface. of the housing and having formed thereon an eccentric or crank arm 18.

there are detachable covers or end housings .110 19which are provided with the arms 20 and.

handle bars 21. The lower surface of the end housing 19 terminates in the present instance, in a flat surface 22 between the arms 20. The ends of the central housin 11 and the detachable housings 19, as we asthe flat surface 22 and handles 21, extend downwardly at substantially right angles to each other, as best illustrated in Fig. 2.

The lower ortion of the central hous ng 11 is provide with a dpair of pms or guide bars 24 rigidly secure thereto, and extending outwardly therefrom. The axes of these bars are parallel with the flat surface 22. Slidably mounted on the guide bars 24, so as to freely reciprocate thereon, there 1s a reciprocating member 25, the upper port on of which is formed into a guard portion (as best illustrated in Fig. 8). It also 1s rovided with a pair of cylindrical openmgs 26 adapted to receivethe guide bars 24 to slide thereon. It will be noted that the guide bars 24 are oifset from the axis of the stationary housing 11 so that their intermediate point will be positioned well to one side of the center of the gear 15.

Carried by the reciprocating member 25 and in the present instance formed integral therewith, there are a pair of rlgid angularly disposed spreading arms 27, said arms also extending downwardly at an angle to each other and supporting on the ends thereof the massaging pads 28. saidmassaging pads are connected to the respective ends of the supporting arms 27 by means of ball and socket universal connections 29 (as shown in Fig. 5).-

Secured to the crank arm 18 there is a crank pin 30 about which there is rotatably mounted the collar 31 having a link connection or pitman 32 with the shouldered pin or journal 33 mounted in the openlng 34 formed in the reciprocating member 25.

Fig. 6 illustrates the pitman when in dead center and shows its angular position with reference to the stationary housing and the reciprocating member. This angular position is caused by off-setting the axis of the reciprocating member from the axis of the stationary housing as above described.-

In operation, upon rotation of the spindle 12, the driving mechanism as above described, will be rotated for causing a reciprocating action of the pitman 32 which in turn will move the reciprocating member upon the guide bars 24. In applying the reciprocating movement to both sides of the machine, the result will be the reciprocation of both pairs of massaging pads toward and away from each other in a straight line, the

' paths of which are indicated by the dotted lines, AA' and BB, and arrows in Fig. 9, of the drawings.

Surface 22 and also the under side of the central housing 11-, as well as the upper surfaces of reciprocating member 25, are all in parallel alignment with the guide bars 24,

and there is very little clearance between the stationary and moving parts, for protecting the hair and nzechamsm as herelnafterset forth. 1

reciprocating member, are positioned so that each arm extends at an angle to the other arm of the same pair, and each arm faces a diametrically opposed arm of another pair carried by another reciprocating member.

The end ofeach arm carries an applicatory member or pad mounted on ball and socket bearings and each pad is thus capable of universal movement. This construction and novel positioning of the arms with respect to the scalp, provides a device in which a comparatively large range of travel can be imposed on the pads without excessive action of the ball and socket joints in order to maintain a constant pressure from each pad.

The driving action of the ends of each arm, adjacent to the hat band area, is tangential to the scalp. The driving action exerted on the pads is also tangential to a large extent, but is modified slightly by the small amount of play on the ball and socket joints, so that the net resulting movement of the pads is absolutely parallel to the scalp. This movement of the pads, accurately following the contour of the scalp with constant pressure, is due to the tangential driving direction of the arms over the area desired. The pads are not tight at one point and loose at another, but they main tain a steady grip on the scalp throughout their entire travel. The worm gears being set at an angle of approximately 90 degrees to one another, enables the pads to maintain their steady grip of the desired area in the most eflicient manner.

Portions of the reciprocating members are formed in straight lines parallel to the direction of travel. Surfaces on the stationary housing, adjacent to the reciprocating members, are also formed in straight lines in the same direction and with very little clearance from the corresponding mating portions of the reciprocating members. In this way an effective guard is formed that alfords the desired protectionat all points of travel.

It will be observed also that the transverse center of the driving worm and the centers of the worm gears, the latter of which the crank pins 30 travel about, are in true alignment. The center of the worm gears and journals 33 are in an off-set position with respect to each other. This construction positions the drivin pitmans 32 m an angular osition e ua to the amount ofthe above 0 -set. This construction makes it possible to mount the motor more closely to an intermediate point between the pa1rs of massaging pads, and the centerof gravity of the machine is then positioned more nearly intermediate the same. This is particularly desirable for obtainin a more balanced machine when moun in o erative position, and causes the weight 0 the machine to be more evenly distributed to the four massaging pads.

From the foregoin descript1on, it Wlll thus be seen that I o tain a very superior gripping effect on the head where it is most needed, and where the action of the pads will tend to increase the blood supply to the upper part of the scalp and counteract the ill eifect of tight hat bands.
