Jan. 16, 1934. R. B. LUTZ SCALP TREATING DEVICE Filed June 16, 1930 Patented Jan. 16, 1934 UNITED STATES PATENT orrlcs This invention is; a device for treating the human scalp.

One of the objects is to provide. a comb-like device capable of being, passed over the human scalp for massage or shampoo purposes, and having means for conducting away loose hairs, dandrufi scale, and other elements which may be. loosened by its operation. A further object is to provide a device of the character mentioned 0 equipped with means for supplementing amechanical massage by applying a suction to the scalp, to stimulatev the flow of blood in the vi cinity of the area being treated. A further ob ject is to provide a suction comb provided with means by which the degree of suction applied to the scalp may be varied.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing:-

Figure. 3 is a detail sectional view illustrating 25. a slight modification. Figure 4 is a side elevation.

illustrating a second modification.

Referring to the drawing, S designates a suction chamber provided with an enlarged bulbous body portion 10' and a cylindrical suction. inlet portion 11,. open at its lower end. Said body portion 10 is provided with a suction: outlet 12, located at any desired position, and. connected by a conduit 13 with a suitable suction device (not shown), operating upon. a. principle commonly. employed in connection with vacuum cleaners.

C designates a comb-member having a cylin-; drical body portion 14, telescoping within theoylindrical inlet portion l0.,..and rotatably and longitudinally adjustable therein. The loweredge of said comb member is provided with teeth 15'. As shown in Figures 1 and 2, the portion 10. of the suction chamber is provided with. oppositely disposed inclined slots 16:, which are en.- gaged by threaded lugs 17, extending radially from the comb member C, said lugs in the form shown in Figure 2', constituting the. ends of a, diametrically disposed rod 17a- The outer endsof said lugs 17 are engaged by nuts. l8,'adapted. to engage the outer surface of said cylindrical inlet portion 10. By means of this arrangement, rotation of the comb member will adjust the same longitudinally with respect to the inlet member 11, the nuts serving to lock said comb-member F in any adjusted position. By making such adjjustments the mouth of the suction member 11 may be brought more or less 'over the openings between the teeth 15 and closer to, or further away from the scalp, to increase or diminish the degree of suction to be applied thereto.

In. practice, it is preferred to employ a flexible 6T9 skirt 19, the .upper edge of which is secured to the suction chamber S, preferably around the portion 11. Said skirt flares outwardly so as to conformfto thecontour of the head, and its lower edge depends below the comb member so as to enclose it.

In lieu of employing the lug and slot engagement. between the comb member and the suction chamber, as illustrated. in Figures 1 and 2, the form. of adjustment employed in. Figure 3 may 0 be employed. Referring. to. the last mentioned figure, the cylindrical. inlet portion 11a is provided with a spider 20, which rotatably supports a threaded adjusting shaft21. Said shaft engages an internally threaded sleeve 22, formed 7 on a spider 23 carried by the comb member C. Said shaft is provided with'av milled head 24' for convenient manipulation, and it is obvious that. rotations. of the shaft 21 will move the comb member inwardly or outwardly, depending upon the direction of rotation.

In the form of the invention illustrated in Figure 4, the cylindrical inletportion 11b is made separate from the suction chamber 101). The two parts may be separably connected in any suitablemanner. For instance, the chamber 101) may be constructed witha collar 25., provided with, bayonet slots 26, which are engaged by lugs 2'7 on the member 111), the upper end of said member extending into said collar. The combmember C is mounted to rotate upon the exterior of the member 11b, and is provided with slots 16b, positioned to receiveradial lugs 17b, carried. by said member 11b.

-In operation, of the respective devices above described, the comb member is adjusted so'that while the device is engaged with the scalp, the desired suction will be applied to the area to be treated. The skirt is thenadjusted to the head and the suction device set in operation. By then moving the device around with the comb in contact with the scalp, a very effective and beneficial massaging. action is produced, which is obtained by combining the mechanical rubbing of the comb, with the suction, which tends to stimulate the local blood flow. At the same time all loose hair, dandruff scales, and the like are carried ofi through the suction device, leaving the scalp clean as well as invigorated.

The advantages of the invention will be readily 9 appreciated by those skilled in the art to which it belongs. For instance, it will be particularly noted that not only is provision made for a simultaneous rubbing and suction treatment of the scalp, but simple means are provided for adjusting the device to suit the individual needs of each person to be treated.

Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is:-
