` MASSAGE DEVICE.

Specification of Letters Patent.

Patented June 4, 1918.

Application led April 16, 1917. Serial No. 162,505.

To all whom it may concern:

Be it known that I, HYAKUTARO HIRoTA, a subject of the Emperor of Japan, residing at Los Angeles, in the county of Los Angeles and State of California, have invented eertain new and useful Improvements in Massage Devices, of which the following is a specification.

This invention has relation to new and useful improvements in massage devices, and

' has for its principal objects the substitution,

in apparatus of this character, of lthermoelectric means for vibratorv means to produce the desired therapeutic efects, and to provide curative and healing means for all ailments which are alleviated by the process of kneading, rubbing, or slapping the afflicted parts, or which may be relieved,

cured, or healed by application of a counter.- irritant or cautery.

This'invention is further designed to provide a construction by which the device may be placed in any ordinary electric circuit, and to provide a Construction by which the temperature of the device may be changed or adjusted to varying degrees from the normal.

The invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed.

In the drawings: Figure 1 is a vertical mid-section of a massage device embodying my invention, showing a friction bulb, and thermo-electric elements therein; Fig. 2 is a side elevation of the same; Fig. 3 is a vertical-mid-section of a modified form; Fig. 4 is a bottom plan view of the form shown in Fig. 3, having the cap and outer casing removed; Fig, 5 1s a section taken on line )x5-X5, of Fig. 1, looking in the direction indicated by the arrow; Fig. 6 is a sectional view taken on line X-Xe, of Fig. 1, looking in the direction indicated by the arrow, and Fig. 7 is a diagram of the electrie circuit and elements shown in Fig. 1.

Referring t0 the drawings: The porcelain casing 7, has at one end a massage bulb 8, rotatably mounted thereon, and retained by flange 9. On the opposite end is a rotatable collar 10, threaded for connection with an electric socket, and having fixed thereto an insulating sleeve 11, for manual operation.

Collar 10 is in constant contact with conductor 12, which in turn is connected with a Contact block 13. In radial and longitudinal grooves 14, are mounted a series of rheostat coils 15, each having a contact block 16. A rheostat adjusting sleeve 17 is rotatably mounted on casing 7, and has an inner contact member 18,Y provided with a projecting lug 19, adapted to engage consecutively the contact blocks and coils as the sleeve is rotated. Thus any number of the resistance coils may be placed in circuit by rotating the sleeve, the various points of resistance being indicated by the marks 20, embossed on member 7, and the pointer 21 on the sleeve. Two sliding spring jacks 22, 23, are fixed to member 7, and one spring ack 22 is in constant contact with the inner contact member 18, the spring jack 23,-extending through member 7, and forming a contact-,24, to engage with an electric socket. Heating coils 25 are mounted on a sliding 'frame 26 in the bottom end of receptacle 7,

said frame having Contact members 27, 28, sliding respectively, in members 22, 23. The frame 26 has threaded racks 29, extending in slots 30 in member 7, and engaging with the correspondingly 'threaded sleeve or bulb 8, the rotation of which will cause a longitudinal movement of the frame, carrying the coils 25 toward and from the friction bottom 31, of the bulb.

In use, this device is to be screwed into an electric socket, which may be done by rotating the independently revoluble sleeve 11, and the temperature of the friction bulb 8 may be varied either by manipulation -of the rheostat sleeve 17, whereby the degree of energization of the heat coils is varied, or by manipulation of the sleeve or bulb 8, whereby the proximity of the coils to the friction bottom 31, is varied. The casing 7 is provided with a knurled flange 32, to facilitate the manipulation of the adjusting sleefe and bulb.

In the modified form shown in Figs. 3, 4, which is adapted for screw connection with an electric socket, the contact members 33, 34, are directly connected t0 a series of heatin coils 35, which are interposed between Imca plates 36. The friction cap 37 is detachable, and all parts are removable.

From the foregoing it may be seen that I have provided a massage device having means for creating a friction of the skin.

lfrictional means,

together With electric heating means, and a means for shifting the heating means to and from the friction means, and means for varying thetemperature of the heating means.

What is claimed is: .fi 1. A massage device, comprising manual thermo-electric means Within the limits of the friction means, means to shift the heatin means relatively to the friction means, an means for regulating the heating means.

2. A massage' device, comprising a casing, a friction bulb thereon, and thermo-electric heating means Within the casing, and means to vary the temperature and relative position of the heating means.

3. A massage device, comprising a casing,

a massage bulb thereon, a heating coil Within the casing, means for adjusting the heating coil relative to the bulb, and means for energizing the coil.

4. The combination with a casing having two oppositely disposed slots, of a massage bulb rotatably mounted on the casin and extending over the slots, a frame slidlng in said casing, racks on said frame extending through said slots and having screwthreaded engagement With the bulb, and

thermo-electric elements carried by said' frame.

5. A massage device, comprising a casing having the bottom end adapted for producing a friction of the skin, thermo-electric elements Within the casing and adjacent to the bottom, a sliding frame Withinthe casing carrying the thermo-electric elements, spring jacks iXe/d Within the casing and in constant contact with the thermo-electric elements, a series of resistance coils Within the casing, a rotatable sleeve mounted on the casing, a contact member carried by the rotatable sleeve, said contact member being in constant contact with one of said spring jacks, and being adapted to make consecutive contact with the resistance coils, and electric socket terminals on the outer end of the casing, one of which extends to the resistance coils and the other of Which eX- tends to a spring jack.

In testimony whereof, I hereunto aliix mysignature, this 11th day 7 of April, in the year 191 HYAKUTARO HIROTA.
