vSpecification. of Letters Patent. Pratlilted `Apr. 16, '1918.

Application filed January 30, 1917.v Serial No- 145,412.

To @ZZ whom it may concern.' I

Be it known .that I, HYAKUTARO Humm, a subject of the Emperor of'Japan, 'residing at Los Angeles, in the county of Los An- I' geles'and State of California, have invented certain new and useful Improvements in p Massage Devices, of which the following is a specification.

This invention relates to massage devices, and more particularlyy to a device of this character in which thermo-electric and other heat producing means are substituted for vibrating 'means to' produce the desired therapeutic effects.

The objects of this invention are, to provide means ecient as va Vcurative and healing device in all ailments of a persons body,

which are ordinarily alleviated by the process of kneading, rubbing, pressing, vor lslapping the afflicted parts, and also such ailments as may be relieved, cured, or healed by the employment of a counter yirritant or cautery.

It is an object of the invention to provide simple andefiicient means for restoring vitality to sluggish organs of the body, and to stimulate and hasten the development thereof, also to provide efficient means for the relief of fatigue, pains, and nervous aections.

To this end, the invention consists in the peculiar construction and combination ofk parts, as hereinafter described and claimed.

While simple and efficient means are herein described for accomplishing the objects of the invention, it is to be understood that the invention is not limitedV to the precise construction shown, but may include within its purview such minor .changes and modifications as may fall within .the scope of the appended claims; the essence of my invention comprising a receptacle adapted for manual use to create friction of the skin and otherwise to knead and massage the same,

of a massage device constructed.r in accordance with the principles'of my invention. Fig. 2 is a vertical mid-section of the same. Fig. 3 is a side elevationof a modified form of the invention. Fig. t lis a verticalmidsection of the form shown in Fig. 3; this form being constructed `with "a detachable end, whereby various forms may be substituted vone for another, adapting the device for various uses. Fig. l5 is a transverse section onV line X5-X5, of Fig. 4,"looking in -direction indicated bythe arrow. `Fig. 6 is a sectional detail of a detachable end tov be attached to the. device sho'wuin Fig. Il. Fig.

7 'is a vertical.mid-sectionV of armodied form employing thermoelectric units to vary the temperature thereof. Fig. 8 is a side elevation of a modified form of the inventionhaving double handles adapted to temperature modifications.

leferringv to the drawings, a form of my invention, as shown in Figs. l, 2, consists ofl the casing 12, having a`lared bottom v13,

provided with apertures 14, and aheat insulated handle 15. rlhe massage face-`16 is slightly rounded. tubular' receptacle 17 is adapted to telescope within the casing 12; being provided witlia lpin 1S, working in the slot'19in casing 12. The receptacle 17 is providedat its upper end with wings 2() by which vit may be more readily manipulated, its movement being limited by the length ofthe slot 19. Y

A screw shaft 21 mounted axially within the receptacle, hasmounted on the outer end, the-operating handle 22, and on the inner jend, the disk o r follower 2.3,;which forces the filler 24, preferably moXa, a substance which burns at a uniform rate of combustion7 and often used by burning it on the skin yas a counter irritant or cautery, downward as the handle 422 is turned.

In use, the skin, or part of the person to be treated, is rubbed or kneaded by applying the massage face 16, thereto; the receptacle 17 having been first withdrawn tok the position shown in Fig. 2, and the filler lighted. The burning of the heat producing element is controlled by the handlev or feed-nut 22, and the combustion is facilitated by admission of air through the apertures 14. The receptacle may be withdrawn for renewal of the filler'. v

In the modified form shown in Figs. 3, 4L,

.the casing' or. bodyu25, is provided with a detachable massage element V,26, screwed to the bottom end thereof. The inner receptacle 27 is smaller vthan and spacediapart from the casing 25, being, in this case, held in .concentric 4.relation with said casing, by radial projecting pins 28 and 29.' These pinsare flXed to the receptacle and are in y contact with the outeiecasing.l

I freely relative to the receptacle, but with-k The feed-nut '30 is mounted to rotate out longitudinal movement, and has a tubular extension 31, threaded at the lower end 32, to engage with the correspondingly threaded shaft 33, having a fixed-circular head 34, and a longitudinally movable follower 35, with a spring 36, interposed between the head and follower to hold the follower in yielding engagement with the moxa ller 24. The head 34 is grooved and held against rotation by engagement withthe longitudinal ribs 37 on the inner wall of the receptacle, and working insaid grooves. Thus the rotation of the feed-nut will cause the longitudinal movement of the follower to force the filler downward as it is needed for combustion.

Various forms of detachable massage elements may be provided for this form of the device; the form shown in Fig. 6 being adapted for rectal use, as for example, in the treatment of piles. To maintain combustion of the heat producing elements when the non-perforated massage elements are attached, the receptacle is pierced at its 11pper end with draft holes 38, admitting air 1 to the interior. The current of air will pass downward through apertures 39, inthe head, and apertures 40, in the follower, thence through the filler which is suiiciently porous for this purpose. The products of combustion pass outward through the annular space between the casing and receptacle, and thence through the draft holes 41.

This device is used in the same manner as that shown in Figs. 1, 2. To stop combustion, the receptacle is forced downward until the filler is in contact with the bottom of the massage element,'as shown in Figs. 3, 4. It may be noted that the pins 28 also proj ect inward, and hold the end of the feednut in concentric relation with the receptacle. A handle 42 is provided to facilitate manipulation of the device.

In the modified form shown in Fig. 7, thermo-electric means are employed for varying the temperature thereof. The outer casing 68, is provided at the bottom with a massage bulb 69, and at the top with a rotating member 7 O. A series of metallic resistance plates 71, adapted upon passing an electric current therethrough tov become heated, are connected with one terminal 72, of an electric conduit. The opposite Vterminal 73, is connected to a Contact member 74, upon the bottom of the rotary sleeve 70, and adapted to engage consecutively, the contact members 75, connected' respectively, torplates 71, upon actuating the member 70.

One or more of the resistance plates 7l may be placed in circuit by rotating the sleeve 70, an indicating means therefor consisting of a pointer 76 affixed to the sleeve,

v the invention may be carried out in various ways and with various modifications, there being in each form shown, a means of varying the temperature of the device above or below normal, while in use, to secure advantages in massage treatment, which could not be obtained in using; the ordinary type of massage device.

The heat producing elements are simple, inexpensive, and easily renewed. The angularly disposed handle lshown in several of the forms is of advantage where the oper-v ator wishes to employ the deviceV in treatment of his own shoulders or his back.

Attention may be called to the fact thatV a thermo-electric receptacle may be constructed for the forms shown in Figs. 1, 2, 3, 4, and 8, and other forms of containers may be substituted and the detachable massage bulbs may be varied within the scope of the appended claims.
