MASSAGE` APPARATUS Dec. 31, 1940. H. w. HAPMAN MASSAGE APPARATUS 5 Sheets-Sheet 5 Filed Dec. l25, 1959 Patented Dec. 31, 1940 UNITED STATES PATENT OFFICE 8 Claims.

My invention relates to apparatus for massaging or otherwise manipulating various parts of the body, and its principal object is to provide an apparatus of this kind, actuated by electric or other form of motive power, which is capable of administering the required treatment in a regular and systematic manner as distinguished from the sporadic and irregular treatments obtained by the use of the vibratory or other hand applicators usually employed.

In order to obtain the quickest and most benecial results it is necessary that the speed, amplitude and nature of the movements used shall be similar during each successive operation upon the same part of the body, so as to insure that the effects of an individual treatment shall not be nullified by the ones following.

Another object of the invention is to provide an apparatus of the character recited in which is employed a flexible and elastic form of applicator of such construction that by its use the beneficial operations upon the body resulting from skillful application of the hands may be produced automatically by the patient himself.

A further object is to provide an apparatus which is quickly and easily adjustable to different positions relative to the body so as to render it practically universal in its application.

A still further object is to provide an apparatus which is simple in construction and economical to manufacture by modern production methods, so that it may be sold at a price which will place it within the reach of persons to whom the cost of the present mechanical devices is prohibited.

With these and other objects in View, I will now describe a preferred embodiment of my improved apparatus, reference being had to the accompanying drawings, in which- Figure 1 is a plan view showing my improved apparatus as driven by means of an electric motor of the rotary type.

Like characters designate corresponding parts throughout the several views.

Referring now more particularly to Figures 1 to 5,'inclusive, of the drawings, I is the base, preferably of cast aluminum, Duralumin, or other light material, having thereupon a support II for the motor 2. The motor 2 is provided with a built-in speed reduction gear 2| of any convenient type, consisting, in the example shown, of a worm upon the motor shaft 22 meshing with a worm wheel upon the right-angularly disposed driving shaft 23. The shaft 23, where it projects from the reduction gear casing, is supported in bearing brackets I2 arranged in spaced relation upon the base and preferably integral therewith, and between these brackets is positioned an eccentric 3, secured upon the shaft, upon which is mounted the strap member 4| which forms part of the vibrator rock shaft 4. The shaft 4 is connected to the base by means of vertical links 5, pivoted atv 5I to lugs I3 upon the base and having at their upper ends bearings adapted to receive trunnions @2 upon the shaft.

In the ends of the shaft 4 are openings 4S within which are secured, as by set screws 44, the free ends of a substantially U-shaped applicator frame which extends outwardly from the base I as shown in Figures 1 and 2. Thus it will be seen that, when the shaft 23 is rotated, the frame 6 will be subjected to a rocking motion about the shaft il and also a longitudinal reciprocatory motion upon the links 5, so that a point upon the frame removed from the shaft l will describe a quasi-elliptical or oval path, as shown diagrammatically at x in Figure 2.

The applicator proper, designated l, consists in the example shown, of a sac-like member of rubber or other elastic material which is slipped over the frame 6 until the closed end 'II comes against the end cross-bar 6I in which position it is rmly held by the stretching of the material. Midways of the member I is an opening l2, as shown in Figure 1, which is intended to receive the nose of the patient when a facial massage is being performed, the face in this case being pr-essed downwards upon the applicator, with the forehead towards the shaft 4 and the chin towards the cross bar 6|.

Now, it will be runderstood that that portion of the applicator which touches. the lower part of the face will have considerably more movement than the portion which touches the upper part or forehead, which is as it should be. It will be observed, further, by reference to the diagram Figure 19, which represents a transverse section of the applicator at that point where the nose projects through the opening l2, that a compound movement of the applicator is produced in the plane of this section, and to a larger or smaller extent in other corresponding cross sections. For

example, the frame 6, vibrating in a vertical plane, causes the material of the applicator to be stretched, at each vibration, in the direction indicated by the arrows z--z, and this, together with the horizontal vibration of the applicator,

F produces a compound movement of the applicator against the surface of the face which has almost the same effect as is obtained by the digital manipulation in the ordinary manual massage, except that itis much more regular and eiiective and, due to the fact that the speed of the vibrations can be adjusted by any of the usual means well known in the art, operations of any desired amplitude may be produced by merely pressing the face more or less heavily downwards upon the applicator.

Secured to the base I as by bolts I4 are bra-ckets 8 cast from light alloy, the said brackets having vertical extensions 8| which serve as handles for holding and transporting the apparatus. Pivoted to the base and to the vbrackets 8 as by bolts I5 is a U-shaped member 9 which, when the apparatus is to be used without the supporting stand, extends forward as shown in full lines in Figures l. and 2, but when the machine is mounted upon the stand it is folded back to the position indicated at 9|. The said member is held in the operative position by means of the set screws I6 which are threaded into the brackets and have reduced portions I6| adapted to enter suitable openings in the member 9. In Figures 4 and 5 of the drawings are shown details of the construction of the eccentric 3 together with the adjacent parts. From these views it will be seen that the brackets I2 are furnished with bushings |2| having upon their adjacent ends flanges |22, the bushings; being of the well known oil-less type, and in order to retain the eccentric strap 4| in position laterally there are provided washers M. The eccentric is rotatably secured to the shaft by means of the headless set screw 45.

The apparatus as hitherto described is obviously suitable only for use upon a table or other elevated support and for conditions where it is desired to store it away when not in use. In order, however, to adapt the apparatus for use in barber shops, beauty parlors, and so forth, I have provided a floor stand as shown in Figures 6 and l of the drawings. This stand comprises a base IUI to which is secured a tubular socket W2, and slidable within this socket is a tubular pillar |03 adjus-tably held within the socket as by the collar Idd and set screw |05. Upon the upper end of the pillar is secured a bracket IBSA, and to this bracket is pivoted, as by the set screw |06, a bracket I'l, the said bracket having an opening in which is slidably supported the horizontal arm Hi8, the same being secured in position by the set screw |09. The arm IBB is provided with an upwardly bent end portion I III on which is rotatably mounted the boss I|2 of a cast metal plate IIA, the boss being secured in position upon the portion IIB by means of the set screw H3. This plate is adapted to receive the base I of the apparatus which is secured in position by means of the bolt ||5 and the thumb nut Ili, as shown in dotted lines in Figure 6. The base I is further secured laterally by means of the projection ||`I which iits within a bushing II8 in the plate IIL'I.

By this arrangement, the apparatus may be moved around in various waysr to suit the convenience of the patient.

My improved apparatus as hitherto described and as shown in Figures l to 5 of the drawings, is intended more especially for facial massage, but it will be understood that the same may be constructed in various forms according to the intended application, and I will now describe two modified forms with reference to the drawings, Figures 8 to 18, inclusive.

One modified form which may be useful in certain `cases might be formed by turning back the member Ii over the actuating motor and gearing, as shown in dotted lines at 6A in Figure 2. In Figures 8 and 9 is shown a variation of a design Which is of particular utility for massaging the leg or arm of a patient. In this modification the member 4 and the member 6 are inclined upward as at 4A, BA, so that the main portion of the frame 6 occupies an elevated position in relation to the base. In such a case it may not be necessary to close the end of the sac-like applicator 1 which may be of trough-like form so that a limb of the patient, designated L, could pass over the top of the motor and driving mechanism. In this case it might be advisable to form the end cross member 6| in a downwardly bent arcuate form as shown at BIA so as to allow the limb to pass through the trough without obstruction from the framework.

In some applications it may be suicient to provide a simple up-and-down movement to the applicator, and this may be readily performed by means of the modification shown in Figures 10 and 11 of the drawings. In this case the member together with the applicator 1, is pivoted at 62 upon a pai'r of rigid brackets |3| upon the base I, and the oscillatory movement may beimparted to the applicator by means of the lever 4G,

tricity. Similarly, in Figures 12 and 13, the memfber 6 is pivoted to the base I as at B3, the rear end being ait an angle to the main portion 6, as

shown in Figure 13. The actuating means in this modification is similar to that shown in Figures 10 and 11. i

In Figures 14 and 15 is shown a modification in which the vibratory frame member 6 is pivoted at 62 to the brackets I3I on the base I, and the actuating magnet is located at the opposite end of the said frame. In this form of my apparatus I prefer to employ an applicator consisting of a single sheet of rubber or other elastic or flexible material designated 13, the said sheet being retained in position upon the frame by means of ears or lugsI I4 having holes by which it is secured to buttons or projections 64. In Figures 16, 17, and 18 I have shown a modified form of my improved apparatus in which the frame 6 is vibrated in a circular direction. For this purpose the frame is provided with four rigid and downwardly extending legs 66 which are held in position upon the base I by means of helical springs S, the said springs; being secured within cup-like bases as SI, and passing around the lower portion of the legs, the upper ends of the springs being adapted to press against collars 61 upon the legs. In this case the driving mechanism comprises the motor 2 having the shaft 22 on which is mounted `an eccentric 3 which operates through a strap 4I, the rod 4I0 of which is rigidly secured as at 4II to a cross member 68 upon the frame 6. With such a construction it is found that while the frame 6, during the first few revolutions of the motor, has an irregular movement, the said movement finally settles down to a truly circular one which resul-ts in a very simple and economical structure, and is highly advantageous for certain forms of treatment.

It will be observed from the foregoing description and by reference to the drawings that I have provided an apparatus which is simple in construction and efficient in operation, an-d while I have herein described several preferred embodiments of my said invention, it will be readily understood by those skilled in the art to which the same relates that various modifications may be made to suit any particular or peculiar requirements without departing from the spirit of my invention as defined in the appended claims. For example, while I have herein shown types of apparatus in which the face or other part of the body is pressed downwards upon the applicator, it may be found advisable in some cases, for example where the apparatus is used in a barber shop or beauty parlor, to invert the vibratory frame and the applicator so that it may press downwardly upon the part to be massaged. Further, since it may be sometimes necessary to vary the period of vibration of the applicator, it will be obvious that in the case of alternating current some variable speed device may be employed for this purpose, while in case a direct current motor is used it may be sufcient to rely upon the variation of speed which will result from different degrees of pressure upon the applicator. Sometimes, moreover, it may be necessary to use a reversible motor.

Further, in those modifications in which a vibrating magnet is shown, it will be recognized that some `other prime mover such as a compressed air cylinder may be used with equal efficiency.

Also, while in the various modifications of my improved apparatus heretofore described, the vibratory movement used combines a longitudinal movement in the plane of the applicator and a movement of smaller amplitude at right angles to the said plane, it may sometimes be found advantageous to combine the said longitudinal movement with a lateral movement also in the plane of the applicator. In this arrangement guide links such as those designated 5 in Figure 2 of the drawings will of course be mounted on vertical pivots, while the eccentric shaft designated 23 will be disposed vertically as will be understood.

One form of this modification is illustrated in Figures 20, 21, 22, and 23 of the drawings in which it will be noted that the driving shaft is disposed vertically, carrying at its upper end an eccentric 3 which is surrounded by the strap 4I having an arm 45 made integral with the applicator frame 6. Pivoted to the arm 45 at 52 are a pair of horizontal links 5, the other ends of which are mounted on the stationary shaft 5IA upon the upper end of the column I3I, being retained in position by the collar 5I B. By this arrangement rotation of the eccentric 3 causes the applicator frame 6 to move longitudinally and also laterally, so as to produce the movement of the applicator as and for the purpose hereinbefore recited.

Having thus described my said invention, what I claim and desire to secure by Letters Patent of the United States is:
