Patented Feb. 20, 1945 vmnA'rmG sHAMroo-nEvion 1 Dan seBern s 'and 'This invention pertains tea-vibrating shampoo device which is portable, self-contained and readily controllable, the device being adapted to shampoo or treat the'hair and to massage'the scalp, thereby facilitating the app'licationof oils, stimulants and preparations useful in the treatment of scalp diseases, elimination oi dandruff, etc. I 1 Generally stated, the invention relates to a portable device having a bodyportion by means of which it can be readily held "and manipulated. The body portion includes an electrically operated, vibratable element, such element being connected to a hollow shampoo headprovi'ded with suitable .massage prongs, suction cups, bristles or the like. Theldevice includes means whereby acsupply of suitable liquids, such soil or other preparation, is supplied to the shampoo headso that the preparation is effectively applied to the-scalp during the shampooing or .massag-. ing operation. v

Itis an object of the present .inventionftherefore, to disclose "a compact, relatively. lightweight, portable vibrating shampoo device which Zincludes ,a reservoir for whatever liquid preparation it-is desired to useorapply.

.A further, obiect of the invention is to :disclose and provide .a "vibrating shampoo device which positively ejects .a desired liquid preparation into use.

As shown in Figs. 1 and 2, the device may comprise-a holl'owbody portion 10 preferably made of molded plastic or thin sheetmetaLl and adapted to form a'handlell by means of which the device may be readily grasped. Extendingirom' theiorward=part oIthe-b'ody portion-is a'vibratable element l2 which'maybe in the form or a provided with an air-ti'ghtfi-nlet closure 2-! Extending upwardly :from the bottom of the reservoirll! is 'an upwardly extending =reentrant tube '22, such .tube being preferablycurv'ed upwardly,

the center of curvature of such reentrant tube 2-2 being preferably located at o'r nearthe center of curvature of the semicircular bend [6 formed in the ivibratable element "[2. The upper end 20f the reentrant tube 22 (within the-reservoir I8) is provided with a port and a check valve 23 cooperating therewith. The'wall of the reentranttube 22 adjacent the bottom of the re ceptale 18 is provided with a'port 24.

The 'vi-bratable element l2 carries' 'a piston 2'5 curved tolslidablyfit thereentrant tdbe 22. This piston' may be attached :tothe vibratable element [2 in "any suitable manner'f as for example, by means of "lock nuts, brazing or the like. air passageway 26' extends through the piston 25 from its 'upperend toblow the vibratable-element 1 2 where itf "forms-an airintake port -'=2-6.- The other end of the "passageway in the end of the piston fifis provided with a check valve 21

' valves

21 and 23 are so arranged that when the piston 25 is rapidly reciprocated within the reentrant tube 22 under the influence of the energizing vibratable element l2, air is admitted into the space between the end of the piston 25 and the end of reentrant tube 22 on every down stroke of the piston 25 and such air is forced through check valve 23 into the reservoir l8 on every up stroke -of the piston 25, thereby forcing air into the receptacle or reservoir l8 in small but positive increments.

A hollow shampoo head is attached to the lower end of the piston 25 in any suitable manner. In Fig. 2 a shampoo head 30 is illustrated as being made from a suitable resilient material, such as for example, a rubber-like composition, preferably one of the synthetic rubber compounds avaliable on the market under the names duprene or neoprene, these compositions being particularly resistant. to oils. The shampoo head illustrated includes a plurality of downwardly extending, pointed fingers 3|, certain of the fingers, such as 32, including ducts 33 extending from the ends of the fingers to the chamber within the head 30, the inner walls of such chamber being indicated at 34.

A conduit 35 extends through the piston 25 and communicates the interior of the shampoo head 30 with a port formed in the side Wall of the piston 25 at a point which is slightly above the port 24 when the device is at rest. When the device is at rest therefore, as shown in Fig. 5, the conduit 35 does not communicate with the interior of the reservoir l8. When the device is placed into operation, however, the conduit 35 is repeatedly brought into communication with the port 24 so as to permit liquid from the reservoir to pass into the conduit and into the shampoo head,

interior of the head 40. Within the head and rotatable upon the inner surface of the plate member 43 is a disc 41 provided with ports or perforations 48 adapted to be moved into coaxial position with respect to the ducts 46. The valve member 41 may be connected to a shaft 49 extendin through a suitable gland 50 carried by the wall of head 40, the upper end of the shaft 49 being bent to form an actuating handle 5|.

A spring 52 may press the valve member 41 in Figs. 3 and 4 a suitable liquid is admitted to the hollow head 40 through the port 4|, the handle 5| having been first turned so as to place the ports or openings 48 out of registry with the ducts 46. When it is desired to use the device as a simple massage no further adjustments need be made. However, when it is desired to apply a treating liquid during such massaging or shampooing, the handle 5| is adjusted so as to bring the ports or openings 48 into partial or complete registry with the ducts 46, this adjustment regulating the amount of liquid which is supplied to the scalp during the masage or shampoo.

Although specific forms of devices have'been described in detail, it is to be understood that the present invention is not limited to the exemplary forms illustrated, since those skilled in the art will appreciate that numerous modifica tions, changes and adaptations may be made. All changes coming within the scope of the appended claims are embraced thereby.

and, as pointed out hereinbefore, air is pumped into the upper part of the reservoir I8 so as to apply a suitable air pressure to the liquid within the reservoir and facilitate the discharge of liquid from the reservoir into the head, whereupon the liquid will be fed through the ducts 33 and discharged from the ends of the fingers 32 into positive contact with the scalp (or other portion of the body to which the shampoo device is applied).

Attention is called to the fact that in the event the shampoo head 30 is pressed but lightly against the head, a massaging action will take place and liquid from the reservoir l8 will be ejected through the ducts 33 against the scalp. When the shampoo head is firmly pressed against thehead a massaging action will take place but the stroke of. the piston 25 will be materially shortened and the amount of liquid which is ejected through the head is reduced or eliminated, depending-upon the size and location of port 24 with respect to the port leading to conduit 35.

In the modified form of construction shown in Figs. 3 and 4, the body portion ID of the device again includes an outwardly extending vi. bratable element l2 which is connected to a shampoo head 40, this head being hollow as shown in Fig. 4 and provided with an inlet port 4| having a removable closure 42, such closure preferably being a minute air hole therein ,so as to permit some air to enter the head.

The base of the head 40 may be removable and may comprise a flat member 43 carrying downwardly extending fingers such as 44, suction cups 45 or bristlea, The fingers 44 may be provided with ducts 46 communicating with the,
