PNEUMATIC DEVICE FOR CLEANING THE SCALP AND HAIR Filed Dct. 20, 1947 INVENT'OR BYY ATTORNEYS Patented June 5, 1951 PNEUMATIC DEVICE FOR CLEANIN G THE SCALP AND HAIR Preston W. Snowman, Medway, Maine Application October 20, 1947, Serial No. 780,861

1 Claim. 1

This invention relates to a device adapted for the removal of. loose dandruff from the hair. More particularly, the invention has reference to a device of the character described which is attachable to a vacuum cleaner or the like, and is so designed as to remove dandruff in a novel and efficient manner upon the setting up of a pneumatic suction.

The primary object of the invention is to provide a device of the type, stated which, on setting up of the pneumatic suction, acts simultaneously on dandruff lying on the scalp, and on dandruff in the hair itself, in a manner utilizing the suction to a maximum extent.

It is, a further important object of the invention to provide a. dandrufi-removing device which in itself is of. small, simple, and inexpensive construction, having no moving parts, and being capable of indefinite use without possibility of getting out of order.

In its broadest aspects, the invention contemplates the formation of a hollow device readily attachable to the conventional vacuum cleaner hose, and embodying a handle and a head from which extends a plurality of small hollow fingers the outer ends of which are wholly open, and the side walls of which are formed with a number of small perforations.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure l is a bottom plan view of a dandruffremoving device constructed in accordance with the invention connected to a vacuum cleaner hose coupling.

Figure 2 is a longitudinal section on line 22 of Figure 1.

Figure 3 is an end elevation, taken from the left of Figure 2.

Figure 4 is aperspective view, on an enlarged scale, of one of the fingers, a portion of the head to which it is attached being broken away.

Referring to the drawing in detail, my dandruff-removing device is preferably of hollow construction throughout, and has one end 5 wholly open and formed in any suitable manner ,for detachable connection to the coupling 0 of a conventional vacuum cleaner or the like.

In this connection, it is pointed out that the particular formation of the open end 5 can and obviously would be varied according to the formation of the coupling C of the particular cleaner or cleaners to which it is to be connected. In the drawing, I have illustrated one type of con.- struction, purely for the sake of example, but other designs could as well be used, it being es-. sential only that the cooperating end 5 and coupling C make a suitably airtight connection.

The open end 5 is taperingly merged, as at 6, into a continuing hollow handle 1, formed for ready gripping by the user. At its other end, the handle 1 communicates with, and is preferably integral with, a hollow head 8, this in the present instance being shown as substantially flat and circular in conformation.

At 9 I have indicated the flat under side of the head, and from this under side or bottom 9 is outwardly extended a plurality of short widely spaced projecting fingers II]. In the drawing, and referring particularly to Figure 1, the fingers are arranged in an outer and an inner series, but this arrangement can be varied if desired. I have found the arrangement illustrated particularly desirable, however, because it in effect staggers the relationship of the several fingers, so that a row of them appears regardless of the direction in which the device is moved through the scalp of the user. This is readily apparent from Figures 2 and 3, Figure 2 showing the fingers as they appear from the side, and Figure 3 showing them as they appear from the end.

The fingers H! are of tubular formation, having open inner ends communicating with the hollow interior of the head 3, and having open outer ends, as shown at II, that present themselves to the scalp. It may be noted at this point that the whole device can be of integral construction, and can be formed of any desired hard material which is suitable, such as aluminum, this construction extending to the fingers Hi.

In the side wall of each finger l0, and spaced from end to end of each finger, there is formed a plurality of small side openings 12, the purpose of which will become apparent when the operation of the device is described.

In the use of the invention, the end 5 thereof is first connected to the coupling C of a conventional vacuum cleaner, not shown. The

, vacuum cleaner being set in operation, it is seen that air will be drawn through the large end opening I I at the outer end of each finger l0, and through the several side openings l2 thereof. The user grasps the handle I, and applies the device to the scalp. In use of the device, the outer ends of the fingers ID are placed directly thereagainst, and the device is then moved by the user over the scalp, with care being taken to keep the outer ends of the fingers, having the large openings 11, in position against the scalp itself, so far as possible. It is, of course, impossible to close the end openings ll completely by pressing the device against the scalp, and I do not propose that this be done, since the device operates with full efiiciency simply byholding it substantially close to the scalp. The underside 9 of the head has the positive 'efiect of pressing the hair down so that all of it is in the vacuum field of the openings [2.

The pneumatic suction set up by the vacuum cleaner causes dandruff lyingon the scalp itself to be drawn into the large openings ll, whence it' proceeds, of course, through the device and V to the cleaner. At the same time, dandruff which is in the hair is drawn through the side openings [2. In this connection, an important characteristic of the invention is that the substantial closing of the end openings II in the manner described above increases the suction through the side openings l2, correspondingly increasing the vacuum field surrounding the side wall of each finger Ill.

Number handle integral with and communicating at opposite ends With said head and coupling; and a plurality of fingers integral with said head, said fingers respectively having bores of constant diameter from end to end of the fingers, said fingers being open at opposite ends and the open ends of the fingers being of the same diameter as the, bores thereof, one end of each finger communicating with the interior or" the head and the other end of each finger being proportioned to be passed over a scalp, said fingers being short and only slightly smaller in diameter than they are long, the fingers being spaced widely apart and defining between them wide clear spaces for engagement between the fingers of substantial amounts of hair, each finger having a plurality of small openings formed in its side wall and spaced longitudinally of and circumferentially of said side wall.
