This invention relates to applicators of the fountain or reservoir type and particularly to an applicator and heater for massage treatments.

It is an object of my invention to provide a simple, inexpensive and highly efficient device for distributing liquids andv semi-liquids under the control of the operator and'for further working the liquid or other material 10 eiiciently into or over a surface. The invention is especially applicable for the distribution of materials for rendering scalp and massage treatments wherein it is desirable to work theapplied material into the scalp or pores of the skin.

Another object is to provide in a device of the class described, means associated with the distributing head for controlling the dispensing or delivery of the material whereby a rubbing or flexing of the head will pro-V duce a substantial pumping action upon the contents of the device, effecting a gradual and uniform discharge and distribution of material. v Y

Another object is to provide an applicator and massage instrument especially designed forscalp and'beauty parlor treatments and having provision for heating the oil ormaterial to be applied as well as controlling in a desired manner the distribution or application of the material.

A further object is to provide an instrument especially adapted for giving hot oil massage treatments to the scalp wherein the V heating of the oil or material is carried on in a predetermined manner through the control of a thermostat and where a thin liquid may be distributed and worked into the scalp or skin only during the brisk rubbing or 40 massaging of the distributing head over the surface being treated.

These rand other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawing, in which 1931. serial No. 548,7?5.

In the embodiment of my invention illus-y A trated the general shape of the device is' somewhat similar toa hair brush, having, as shown, a truncated conical distributing head 10, an elongated handle 11 anda flat back which is adapted to rest upon asupporting surface withthe distributing head in invertedv position. The body of the device; if'desired, can be in the form Vof an integral casting or stamping and material, such as a metal or bakelite may be conveniently utilized. As E shown the body is in the form of a casting and head l() is-hollow while the back of the handle 1l is provided with a longitudinally extending groove 11a lcommunicating with the hollow head and adapted to accommodate type is housed within distributing head 10 preferably being affixed to the inner surface of back plate 12. As shown this heating unit is of shallow cylindrical shape having a metal casing and provided with a heating element 13a which may be embedded in suitable insulating material disposed within the casing of the unit. A thermostatically operated switch 14 is preferably associated with the heating element and may be mounted within the body or distributing hea-d, aihxed to the top ofthe heating unit. One of the contacts ofthe thermostatic switch is connected by a wire l5 to one end of the heating element 13a and the other contact of the thermostatic switch is connected with one of the lead wires A within electrical service cord C. The second lead wire B connects with'the 0pposite terminal of heating element 13a.

A conventional temperature indicator l16 may be mounted within the wall ofthe body or distributing head having its inner side subjected to the heat therewithin and as shown having a graduated dial readable from the exterior of the device. Y

The reduced end or side of the body or distributing head 10 is open, terminating, as shown, in an annular externally threaded edge to facilitate the inserton and removal of a supply container 17 which may be lled withloil or any other` desirable liquid or semiliquid'substance. Container 17 has an open upper end defined by an inturned vflange which is-provided'primarily for the purpose offurnishing a fingergrip to facilitate removal of the container from the device. The inne-r end of the container is adapted to 'engage and rest upon the top or inner end of the eating unit 13.

Adischarge controlplate 18 Vas fshjown in the .form of an independent thin metallic disk covers the open outer end-of container 17 and has provigiled therein one or .morerelatively small rdischarge ports 18a. The peripheral portion of the plate is .adapted to engage and be seated against 'theinturned flange of container 173 as well as, Vif desired, a portion of the annular edge of the distributing head V10.

A flexible massage-cap 19 covers the discharge controlling plate 18 as well as the end of thel distributing head and as* shown isof dis-k form being constructed of some suitable flexible and elastic material, such as rubber. This cap may have `a shallow circular recess :whereinld-isk l'is seated leaving van annular sealing flange 19a which is adapted to engage the annular edge of `the distributing head. Cap I9 isalso provided with a series of spaced massaging Vand distributing teats 19?) which teats k,protrude substantailly normalto the upper surface thereof and Vwhich fare preferably integrally constructed with the body of the cap; yThe cap is also provided with transverse discharge ports 190 located immediately adjacent -at leastl annum-ber of the i massaging teats in such position that the liquid or other material will be discharged upon the teats and worked to the ends thereof. If desired these discharge ports may be formed axially of the teats.

Massage cap 19 and discharge controlling plate 18 are held in operative position upon the open end of the distributing head 10 by a retaining ring 20 the peripheral wall of which is threaded to engage the externally threaded cylindrical end of the distributing head and this ring is provided an inturned flange 20ct whch engages the marginal edge ofthe flexible cap 19 serving to clamp the sealing flange 19a of the cap against the edge of the vdistributing head.-

In the form of distributing head and discharge controlling plate illustrated in detail in Figsfl to 6 inclusive the controlling plate 18 has a substantial and central portion thereof of concavo-'convex lconstruction providedwith a series, as shown three, -discha11gc apertures 18a. This concave-convex central portion normally seats tightly against the inner or bottom surface of the massage cap forming a liquid-tight yjoint therewith and preventing dripping of the liquid or other parts are normally held in close relationwith the discharge vpor-t of the controlling plate sealed. I preferably provide 4a heavy pad of efficient heat-insulating material between theV casing of the heating unit 13 and thegback or cove-r plate 12.

In operation the oil or other material is placed within supply Acontainer 17 by Vremoving the threaded retaining ring 20 and withdrawing'the container. The ldischarge controlling plate 18 `and Imassage cap 19 'are then Voperatively applied over the 'outer end of the distributing head and clampedingplaoe.

by means of the retaining ring. The circuit through the heatin element iis then closed by manipulation o a suitable switch (not show-n) and the liquid or other'material will then be .heated to a predetermined temperature (in oil scalpmtreatments usually from 149 to 17'5 degrees'FJ.

The handlell ofthe device may be grasped and distributing head' turned to normalposition withjthe massage cap directed downwardly. The projecting lugs ory teats 196 will then be vigorously rubbed Jover the scalp massagingthe same and producing' a flexing` of the cap as illustrated -in Fig. 5. This :flexing Aof the cap produces a `pumping suction.

between the inner surface of the cap and the discharge controlling plate causing small quantities of the liquid or other material to be discharged through the ports 19o into the base portions of the teats, which material is worked down to the tips of the teats and onto the scalp by the massaging action.

Between the strokes of the massage treatment and when the device is normally held with the distributing head directed downwardly no liquid or material will drip from the discharge ports 19o, since at that. time the massage cap 19 is snugly seated against the discharge controlling plate and since the discharge ports 18a of the controlling plate are not in alignment with the discharge ports of the cap a flexible seal is formed for the ports 18a.

The thermostat 14 is eii'ective to maintain the liquid at a predetermined temperature and the temperature indicator 16 will show the operator when the oil has been brought up to adequate temperature for treatment.

The cord C may be detachably connected by a plug with the outer end of the handle, if desired, to enable the device to be utilized without carrying the cord in giving a treatment.

The feeding or distribution of liquid or other material is very uniform due to the cooperation between the discharge plate and my flexible massage cap which is usually constructed of rubber. In commercial use, as in beauty parlor work, the cap may be removed after each treatment and sterilized to conform to sanitary requirements for barber shops and beauty parlors.

en not in use the device may conveniently rest upon the flatbaclr plate 12 which as has been stated is insulated from the heating unit 13 so that it will not scorch a table or other support on which it rests.

From the foregoing description it will be seen that I have provided a simple and highly eliicient applicator and massage instrument capable of being manufactured at low cost and especially well adapted for giving hot oil massage treatments, although capable of wide general use in applying liquids or semiliquids for cleaning, massaging or other distributing purposes.

It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of the parts without departing from the scope of my invention, which, generally stated consists in a device capable of carrying out the objects above set forth and in the novel parts and combinations of parts disclosed and delined in the appended claims.
