Box 902, Montgomery, Ala. 36102 Filed May 10, 1965, Ser. No. 454,448 6 Claims. (Cl. 128-56) ABSTRACT OF THE DISCLOSURE Apparatus for massaging and exercising the scalp of the head embodying a pair of downwardly and inwardly curved arms, on the lower ends of which are mounted either hand operated or motor driven brushes, the brushes being mounted for universal movement relative to the head, and handles immediately associated with the brushes by means of which the brushes may be moved inwardly and upwardly while rotating the same, thus to exercise the scalp.
This invention relates to apparatus for massaging and exercising the scalp of the head for the purpose of stimulating the flow of blood to the roots of the hair, thereby exercising and toning the hair itself.
It is generally accepted that the loss of hair and continued loss of hair, particularly among males, is due to the fact that for some reason unknown to medical science, but generally with increasing age, the scalp becomes drawn tautly over the skull. It is theorized by some that this tautness causes the individual blood vessels feeding each hair to be starved, whereby the roots of the hair, being deprived of their life-giving fluids through the blood stream, simply die and fall out.
It has likewise been theorized and generally recognized that regular and vigorous exercise of the scalp is beneficial in maintaining and restoring circulation to the roots of the hair. However, such exercise heretofore has taken the form of manipulations on the scalp which tend further to stretch it, such exercises being commonly performed with the tips of the fingers, vibrating pad-like machines, etc.
With all the foregoing in mind, and with the idea that deep down circulation of the blood to the individual roots of the hair in fact is beneficial for such roots (although certainly, I do not claim that my invention grows hair), I have provided a simple and efiicient apparatus for getting such deep massaging of the scalp. Briefly, my invention proceeds upon the theory that by engaging the sides of the head generally in the temple areas with a set of brushes of the like and then moving those members upwardly in pressing contact with the scalp, the scalp is caused to flex, wrinkle and knead, in an upward direction, thus imparting considerable movement and energy to the scalp, well beneath the skin. In other words, by manipulating these brushes or massaging elements from lower positions toward the crown of the head, the scalp is buckle-flexed, kneaded or rolled upwardly, resulting in a most unusual type and degree of massage which has the effect of loosening the scalp and permitting the blood vessels therebeneath to supply the roots of the hair of the scalp. Further, I provide means to prevent the massaging elements from directly contacting the crown of the head, upon completion of the upward movement thereof. Still further, the massaging units, which may be rotary brushes or brushes which are hand operated through a relatively small arcuate turn upon each upward stroke, are mounted in universal manner so that on the upward stroke they lie against the head in proper manner.
Apparatus illustrating features of my invention is shown in the accompanying drawings forming a part of this application, in which:

'Referring now to the drawings and more particularly to FIGS. 1 to 6 inclusive, my improved apparatus comprises a supporting framework embodying a pair of downwardly curved arms 10 and 11 disposed to straddle the head. The arms 10 and 11 may he made of rod-like material and may be pivoted at their upper ends 10* and 11 to a common connecting member 12. The member 12 may be generally U-shaped in cross section as shown in FIG. 2 and may embody a lower wall section 12 and side walls 12 The ends 10 and 11 of the arms 10 and 11 are pivotally connected to the side walls 12 by means of cross pins 13. The wall 12 extends outwardly beneath the pivot pins 13 a distance sufficient to form stops by engagement with the arms 10 and 11, thus to limit inward movement of the lower ends of the arms substantially to the dotted line position shown in FIG. 1.
At the lower ends of the arms 10 and 11 I provide extensions or lower sections 14. The sections 14 are secured to the lower ends of the arms 10 and ll by means of the male and female coupling elements 16 and 17 shown in detail in [FIG- 6. Thus, the extensions 14 are free to rotate generally in a plane embodying thelongitudinal axis of the lower ends of the arms 10 and 11.
Mounted on the lower ends of the extensions 14 are the brushing or massaging units indicated generally by the numeral 18. In view of the fact that each of these units is identical a description of one will sufiice for both. First, it will be noted that each unit embodies an outer arcuate casing or housing 19. Outstanding lugs 21 are provided on the housing. A pin 22 passes through these lugs 21 and through the lower end of the extensions 14. Thus, the entire housing is substantially universally mounted relative to the head to be operated upon.
Each housing has a forwardly extending handle 23. Located generally at the junction between the handle 23 and the housing 19 is the armature 24 of an electric motor having a shaft 26 carried thereby and journalled at 27 in an end wall 28 of the housing 19. The field winding is indicated diagrammatically at 29. Current for the motor 24 is supplied through leads 31 which enter the end of the handle 23 as shown. A branch lead 32 carries current to the opposite one of the motors of the unit 18, the lead 32 being secured to the frame members 10 and 11 by clips 33 as shown in FIG. 1.
Surrounding the shaft 26 is the body portion 30 of an elongated, generally cylindrical brush carrying bristles 34. Thus, when the motor 24 is energized the brush turns. Further, as shown clearly in FIG. 1 the righthandmost brush as viewed in that figure rotates clockwise in the direction of arrow 36 while the lefthand one operates counterclockwise in the direction shown by the arrow 37.
I have found that it is important to select the proper length, size and stiffness of bristles in order for my improved device to be fully effective. By way of example, I have found that a brush embodying nylon bristles of about .025 inch in diameter, and having a length from the body portion 30 of about one inch is entirely satisfactory. This strength and length of bristle affords adequate scalp manipulation without uncomfortable stiffness. A speed of about 120 rpm. appears to be satisfactory.
From what has been described it is now possible to explain fully the method of using my improved apparatus. First, while the user may effectively employ my improved device in a sitting, or upright standing position, it sometimes is advantageous to employ the same while bending over, that is, with the head generally lowered as shown in FIG. 8. At all events, whatever the position of the operators body he grasps the handles 23 in his hands and with the motors energized and the brushes turning in the direction of the arrows 3637, that is, with adjacent surfaces moving upwardly, the user applies the brushes to the lower portion of the head generally in the area of the temples. Starting in this area the brushes are pushed more or less firmly inwardly, depending upon the amount of exercise desired and the comfort thereof, and both hands are moved upwardly, simultaneously, bringing the brush units generally to the position shown in dotted lines of FIG. 1. At this position the lower sides of the arms 10 and 11 contact the ends 38 of the wall 12 of the coupling unit 12, thus automatically limiting any further inward movement of the brush units. During the upward movement of the units the scalp of the head is buckle-flexed, rolled or kneaded in an upward direction, producing deepdown exercise thereof. Furthermore, since the brush units are universally mounted relative to the supporting arms 10 and 11, the user is quite easily enabled to maintain the same in contact with the general contour of the head during the upward motion. Having reached the upper limit of the stroke as indicated by the engagement of the arms with the stops 38, the user continues the up movement until the bristles are clear of the head, whereupon he opens the unit, pulls the brushes down and places them against the head just above the ears and commences the stroke again. Again, the oppositely rotating brush surfaces engaging opposite sides of the head, in combination with the upward and inward movement of the brushes, remaining in contact with the head, assure the rolling and kneading of the scalp as herein mentioned, consequently stimulating the flow of blood through the blood vessels in the subcutaneous layers of the scalp. Further, such kneading and upward rolling motions imparted to the scalp tend to loosen it, not as heretofore attempted, by pressing it downwardly, but by the kneading and rolling action in an upward direction. The degree and amount of stimulation may be regulated by the user of the device by the amount of inward pressure that he applies to the handles. Since the adjacent surfaces of the brushes rotate upwardly, the tendency is for the units to move down the head. Manually pushing the brushes upwardly while they are attempting to roll downwardly greatly magnifies the buckle-flexing of the scalp.
In FIG. 7 I show a somewhat simplified version of my improved device. This consists essentially in substituting for the motorized units 18 hand brushes 39 which have the forwardly projecting handles 41. Except for this substitution the unit of FIG. 7 is identical with the motorized one. However, in operation instead of the brushes rotating the user grasps the handles 14 and with the upward movement simply gives the brushes a partial twist by twisting the wrist, thus buckle-flexing the scalp during upward movement of the brush units. The stop means indicated at 38 is provided. Likewise, the universal mounting of the brushes is maintained through the joint 16-17 and the mounting lugs 21 and pin 22.
In FIG. 8 of the drawings I show my improved device being used by a person with his body bent slightly forwardly and his head down. A t t y si the device in this manner the natural flow of blood to the head is enhanced and it is believed to be more beneficial in securing and promoting flow in the blood vessels leading to the individual hairs of the head. Such position is less tiring because the arms are moved to and from raised and lowered positions in a natural fashion.
From the foregoing it will be seen that I have devised an improved apparatus for vigorously exercising, massag ing and stimulating the scalp of the human head. As stated, I make no claim that my improved apparatus actually will grow hair where hair once has grown and yet has died. On the other hand, I do claim that regular and conscientious use of my improved device will so stimulate the scalp, encourage the flow of blood in underneath the skin areas and otherwise tone-up the scalp as to be of important benefit in a person retaining what hair he has. I have proven this to my own satisfaction. Further, I have found that providing some means to stop the massaging adjacent the crown of the head itself is important. Such means prevents pinching of the scalp in the crown area and keeps the brushes from intermeshing.
While I have shown my invention in but two forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
