SCALP TREATING DEVICE ma Feb. 1, 195.5
Patented Jan. 19, 1937 UNITED STATES" PATENT OFFICE 1 Claim.
This invention relates to a device for treating ones scalp for the purpose of increasing the circulation of blood to stimulate the growth of hair.
One of the objects of the invention is to produce a device of this kind which is of very simple construction and which will operate to subject the scalp to a succession of light blows and also to provide for forcing air against the scalp when the blow is struck; also to provide means for subjecting the scalp to a partial vacuum effect im medlately after the blow has been struck.
A further object of the invention is to provide simple means for subjecting the scalp, at a plurality of points, to sudden reverses ofpressure; that is to say, alternately forcing the air against the scalp with a development of a partial vacuum at the same point.
Other objects of the invention will appear hereinafter.
The invention consists in the novel parts and combinations of parts to be described hereinafter, all of which contribute to produce an efficient scalp treating device.
A preferred embodiment of the invention is described in the following specifications, while the broad scope of the invention is pointed out in the appended claim.
In the drawing:
Figure 1 is a side elevation of a scalp treating device embodying my invention;
Fig. 2 is a bottom plan of the device to illustrate the face that is applied to the scalp;
Fig. 3 is a vertical cross section, taken on the line 3-3 of Fig. 2, with the upper portion of the apparatus broken away; and
Fig. 4 is a bottom plan of a cam which I prefer to employ for actuating the plungers that subject the scalp to light blows. This View is taken on the line 4-4 of Fig. 3, looking upwardly and showing the upper ends of the plungers through which this section passes.
Referring more particularly to the parts, the device preferably comprises a small electric motor I which can be held and manipulated by means of a handle 2 that projects out from one side of the motor casing. The electric motor is supplied with electric current through an electric cord 3 and extends inwardly through the handle. The motor shaft has an extension shaft 4 (see Fig. 3) and this shaft is housed in a tubular extension or sleeve 5 which extends out from the lower side of the motor casing and which is preferably provided with screw threads 6. This sleeve 5 supports an applicator head 1 which may be formed of any suitable material, but which I prefer to form of glass. The body of this applicator head I is in the form of a relatively thick disc 8 from which an integral sleeve 9 extends upwardly and this sleeve is threaded internally for attachment to the sleeve 5.
The applicator head I can be locked in any desired adjusted position by means of a locknut or ring II] which is also received on the threads 6 and which is used as a jam-nut to be tightened against the upper end of the sleeve 9 after the same has'been adjusted to the desired position.
The head 1 has a smooth, lower face ll, through which a plurality of small chambers l2 are formed, which chambers are preferably in the form of bores of small diameter formed in the bushings I3, respectively. These bushings are received in counterbored openings M in the head and their inner ends extend beyond the disc 8 of the head and are threaded to receive clamping collars l5 that screw onto the threaded inner ends of the bushings. In each chamber I2 a small piston or head I6 is reciprocated at a rapid rate, and these pistons it constitute the forward ends of plungers I'l, respectively, the rear ends of which are guided through the collars l5. These plungers I! are reciprocated through the agency of the extension shaft 4. In the present instance they are reciprocated through the agency of a cam IB and return springs 19. I prefer to provide four of the chambers l2 and these are disposed circumferentially about the axis of the shaft 4. The cam may have any desired form, but in the present instance it is a double cam of disc form; that is to say, this cam has two diametrically opposite cam faces 20 and 2| which incline circumferentially between two diametrically opposite radial shoulders 22 and 23. The inner ends of the plunger I! have rounded noses 24 that rest against the inclined cam faces 20 and 2|. As the cam is rotated by the shaft 4 the cam face drives the plunger forward at a high velocity until the corresponding shoulder 22 or 23 passes the rounded nose 24 of the plunger, whereupon the spring IQ of the plunger quickly withdraws it or returns it from its forward position. The springs preferably thrust against small washers 25 held in place by small pins 26, respectively. The springs are received in an annular chamber 2'! formed between the plunger and the bore of the bushing, and the outer end of each spring thrusts against a shoulder 28 which projects in from the bore of the bushing and which operates also as a stop for the inward movement of the plungers.
The plungers have a very small travel but are reciprocated at a very high speed. At the limit of their forward stroke they project slightly beyond the face ll of the head 1. The pistons l6 preferably fit closely in the bores so that when they come forward the air in the chamber l2, in advance of the piston, is forced against the scalp; and, on the return stroke, each piston I 6 'will develop a partial vacuiun in the chamber if the face I I, around the edge of the chamber, is held against the scalp. In this way the scalp-will be subjected to asuccession of very rapid and light blows and as the blow is struck air is forced against the scalp. As pointed out above, as each plunger withdraws, partial vacuum will be formed in the chamber 12 if the edge. ofl'thatv chamber is held against the scalp.
