Patented Feb. 18, 1941 UNITED STATES PATENT oFFlcE N POWER DRIVEN SHAMIPOOING DEVICE Application October 8,
'This invention relates to a shampooing device. More particularly, this invention relates to a power driven shampooing device in which the scalp contacting portions of the shampooing fin- 5 gers move in and out in a manner simulating the movements of -a persons lingers in shampooing.
Heretofore a number of massaging apparatuses have been devised for use in connection with facial massages and the like. These devices are inapplicable for use in shampooing and massaging of the scalp and hair in view of the fact that the prior art devices either provide a rotary motion, which obviously would cause the hair to become entangled in the rotating members, or such devices provide merely a vibrating action which is insufficient for proper shampooing and massaging of the scalp and hair, or failed to provide the desired individual in and out motion of the fingers. l 20 In prior commercial practice the scalp and hair has been massaged and shampooed by the ngers of lthe operators and no mechanical devices have been available which provide the suitable individual in and out movement simulating the movement of ones lingers. Furthermore, due to the manual effort necessary for hand massaging and shampooing, the scalp and hair commonly have not been properly massaged and shampooed. In view of the widely recognized beneficial results obtaining from thorough andproper massaging of the scalp, the industry has long desired a device which was power driven and which would provide for a thorough shampooing and massaging action simulating the movement of ones lingers in shampooing and massaging.
It is an object of this invention'to provide a plurality of lingers and power driven means to impart the desired individual in and out movement to the scalp contacting portions of the fingers to provide for proper massagingr and shampooing of the hair and scalp. It is a'further object of this invention to provide delivery and control means so that the liquids used in shampooing may be delivered through the shampooing device, readily subject to control by the operator, and delivered onto the scalp and hair being massaged in close proximity to the shampooing iingers. It is a further object to provide separate control means for the soap and water used in shampooing so that the desired amount of either will be readily available. It .is a further object to utilize the liquids used in the shampooing operation as the lubricants for the ringer driving` mechanism.
55 It is a further object of the invention to provide 1938,1Serial No. 233,984
rubber shampooing fingers, metallic pins disposed l therein, means to mount the pins for oscillating movement, and power driven means to oscillate individually the pins and in turn the shampooing fingers, i. e., to provide the desired individual in 5 and out movement of the scalp contacting portions thereof. It is a further object of the inl vention to provide a plurality of shampooing lingers disposed about a center and: to provide means to move the scalp contacting portions of the lingers substantially radially towards and away from said center.
It is a further object of the invention to provide a device which is simple, compact, economical as to cost of manufacture and cost of operation, and capable of operating for relatively long periods of time without requiring mechanical attention.
The above mentioned general objects of our invention, together with others inherent in the same, are attained by the deviceillustrated in the following drawings, the same being preferred exemplary forms of embodiment of our invention, throughout which drawings like reference numerals indicate like partsz' Figure 1 isa vertical sectional View with parts 25 shown in elevation of a device embodying this invention and with parts broken away and with the lingers shown in a full line position and a dotted line positionfor two of the ngers to illustrate the movement of the lingers;

Referring to Figs. 1 and. 2 of the drawings, an enclosed flexible cable II, which is of common construction and is broken away, connects to a suitable source of power (not shown). A pinion I2 is mounted on the internal driving member of cable II and serves to transmit power therefrom to the bevel gear I3. The bevel gear I3 is connected to the cam I4 (see also Fig. 4) and may be integral therewith as shown in Fig. l. Cam I4 is provided with suitable trackways I5 and I6 for reception therein of the portions I'I of the pins I8. The pins I8 are embedded in a rubber supporting means I9 which may be integral with the rubber fingers 20. The pins I8 are provided with pivotal mounting members 2| which are ernbedded in the rubber supporting means I9. Plates 22 and 23 are mounted on the lcntiposit'e faces of the rubber supporting means I9 and are spaced apart by means of an annular ring 24. Hollow pins 25 connect between the plates 22 and 23. One means of securing the pins 25 to the plates is by expanding the ends of the. pins asv shown in Fig. 6. The openings 26 (see also Fig. 3) of the hollow pins 25 serve as passageways for delivery of iiuid in the chamber 21 onto the scalp being massaged. As a means of securing the device together, the plate 22 abuts the shoulder 28 in the housing 29 and the annular ring 36 is threadedly connected with the housing 29 and serves to retain the plates 22 and 23 in proper place.
I 'I'he flexible conduit 3| (see Fig. 2) is broken away and connects to a source (not shown) of liquid soap under pressure. The liquid soap in the flexible conduit 3| is urged into the passage'- way 32. A valve member, comprising spring 33, valve means 34 and plunger 35, serves to control the flow of liquid soap from the opening 32 into the passageway 36. Liquid soap which is permitted to enter passageway 36 moves into the chamber 2l and thence out openings 26 onto the scalp being massaged.
The exible conduit 31 is broken away and connects to a source (not shown) of water under pressure. 'I'he water in flexible conduit 3'I enters the passageway 38. The valve mechanism, comprising the spring 39, valve means 40 and plunger 4I, serves to control the passage of water from the passageway 38 to the passageway 42'. Water entering the passageway 42' is delivered into the chamber 2l and thence out openings 26 onto the scalp being massaged. The liquid soap and water in the chamber 2l surround the bevel gear I 3` and pinion I2 and serve as lubricants for said bevel gear and pinion, as well as lubricants between the portions I'I of the pins I8 and the track- Ways I5 and I6 of the cam I4.
In the operation of the device shown in Figs. l to 6 inclusive, a source of liquid soap under pressure and water are connected to the flexible conduits 3| and 3l, respectively. The motor-driving the flexible cable II is started. 'I'he speed of drive of the fiexible cable II may vary greatly within the scope of this invention. In a practical embodiment of this invention, we have found it satisfactory to drive the flexible cable II at -a speed of about 250 r. p. m. The rotary motion on the internal driven member wit-hin the flexible cable I I is imparted to the pinion I2. The gear movement will be imparted to the fingers.
aasama ratio between the pinion I2 and the bevel gear I 3 may also vary greatly. In said practical embodiment of this invention with the pinion I2 rotating at the rate of 250 r. p. m., we provided a gear ratio of substantially four to one between the pinion I 2 and the bevel gears I3, i. e., substantially fourrevolutions of the pinion to one revolution of the bevel gear. This provides for movement of the fingers 20 in and out at a speed providing the desired massaging and shampooing action. Preferably the speed of the fingers is suiiiciently slow to permit the fingers to positively move in and out. In view of the fact that the rubber fingers contact the scalp and the rubber fingers have positive give therein, too great a speed will lessen the effectiveness of the device and little Rotary movement of the bevel gear I3 provides similar rotary movement to the cam I4 which is secured to the bevel gear. The portions I1 of the pins I8, Which fit within the grooves I5 and I6 of the cam I4 are preferably rounded as indicated in Figure 1, so as to follow thegrooves I5 and I6 with less friction., As the cam I4 rotates, the portions II of the pins I8 move individually in a radial direction on pivot members 2 I. Preferably the plate 22 is cut away to provide openings 42 which are somewhat larger than the radial movement of the pins I8 at this point. This will reduce the compression of the rubber I9 at this point and facilitates the oscillating movements of the pins I8 in radial direction. Also preferably the rubber I9 is cut away atV 43 to likewise facilitate the oscillating movements of the pins I8. As the pins I8 oscillate, their lower end portions supporting the rubber fingers 26 cause the rubber fingers 20 to move individually in and out in a radial direction. As the rubber fingers 20 move in and out in a radial direction, the operator may depress plunger 35 to introduce soap into the chamber 2l' and depress the plunger 4I to introduce water therein. The water and the soap serve to lubricate pinion I2, bevel gear I3 and the portions II of the pins I8 in the trackways I5 and I6 of the cam I4. The pinion I2 and bevel gear I3 also serve to thoroughly intermix the soap and water so that the liquids are delivered onto the scalp adjacent the fingers 20 in the desired condition for the shampooing and massaging treatment of the hair and scalp.
In Fig. 7 of the drawings, we have shown an alternative construction where a finger 20 is provided with a pin 44 which may be substituted in place of the pins I8 in Figs. l to 6 inclusive. The rubber supporting means 45 may be substituted for the rubber supporting means I9 of the earlier figures. The member 46, on the pin 44, serves as a pivot means in place ofl the pivot mounting member 2| of the previous figures. Also preferably the opening 4l is used for the same purposes as the opening 43 shown in Fig. l. In place of the rounded portion I I shown in connection with pin I8 there may be used the ball member 48 which is rotatively mounted on the pin 44. Such rotatively mounted ball members 48 will follow the trackways I5 and I6 of the cam I4 with re'- duced friction.
We have provided a further alternative construction for the pivotal support of the pins in Figs. 9 and l0. In this modif-led form of the invention the parts similar to the parts shown in Fig. l of the drawings are provided with the same numbers or are broken away, and in the interest of brevity will not be repeated. The pins 49 have rubber fingers 50 thereon. In this form of the invention the three centrally disposed lingers 2D, see Fig. 3, are eliminated and the fingers are all disposed in substantially a circle about a given center. Preferably a rubber sealing member I is formed integral with the iingers 50 to prevent the escape of liquids around the fingers. Pins 49 are provided With ball members 52 to serve as the pivotal supports. Two plate members 53 and 5 4 are provided with mating cup shaped openings to serve as bearings for the ball members 52. In
this form of the invention the ball members 52v are the pivotal supports and oscillate in metallic bearings provided in plates 53 and 54. In Fig. 10 the same pivotal support is provided as shown in Fig. 9. Here the rubber sealing member 5I is eliminated and the rubber fingers 55 aremolded with cutaway portions to interfit with iianges 56 preferably formed integral with the pins 51.
In Fig. 8 of the drawings we have provided'a modified form of the invention where the soap and water are each delivered separately and are not premixed prior to application on the scalp and hair. The passageway 36 connects by a conduit 58 with the centrally disposed opening 62. Thus by operation of the plunger 35 the soap may be delivered directly onto the scalp and `water may be delivered by operation of the plunger 4l as previously described.
' As an alternative method of driving the cam Il shown in Figs; 1 to 6, inclusive, and thence thefingers, the shaft 59 in Fig. 8 is connected by a flexible cable (not shown) to a source of power. Worm 60 intermeshes with gear 6l which` is in turn connected with cam i4 by any suitablei means.
In the foregoing description of this invention, we have illustrated the'iiexible cable to connect the shampooing device to a suitable source of power. By this well known means the weight of the motor is not carried by the shampooing device. However, if desired, instead of the usual flexible cable connection for transmitting the power, the motor may be directly mounted on shampooing device and connected to provide the proper rotary motion of the cam. Also we have shown a plurality of manners'of pivotally mounting the fingers 'so that'the iingers will individually move radially in an in and out manner to properly simulate the in and out movement of the iingers of a person in massaging or shampooing;
f members mounted about a central axis; a plurality of pin members each having one end portion disposed within a finger member; pivot means carried by and disposed intermediate the length of the fpin members; a rubber supporting means mounting said pivot means, whereby each pin member may oscillate with said pivot and rubber supporting means serving as the pivotal support; and
means to individually oscillate the other end por-v tions of the `pin members in a radial direction as respects the said central axis.
