ATTORNEY Patented Apr. 29, 1952 UNITED TATES PATENT OFFICE HAIR REMOVER WITH CENTRAL FEED OF SKIN LOTION 1 The present invention relates to a pocket device useful to remove hair and stubble from the skin of a person, for example from the arms I or legs, and is concerned more especially with a device, by the aid of which, the hair is removed by an abrading action and simultaneous ly the skin of the user anointed with soothing liquid such as an oil, that feeds from within the abrading element and works into the skin to prevent irritation.

The invention aims primarily to effect removal of unwanted hair from ones person quickly and efficiently and in the least annoying manner possible and to provide a pocket size device for the purpose that will include the abrading element and a self-contained reservoir for a soothing liquid which together and in combination are constructed and adapted to function as valve means and pumping means adapted when operated to discharge the soothing liquid through the abrading element from the interior thereof to the exterior surface and thence in intimate contact with the skin of the user.

While it is known to use sandpaper to cut and rub. off hair from ones person, sandpaper is difficult properly to manipulate and its cutting action is harsh and irritating, so much so that the skin becomes painfully sensitive and sore to the touch. The present invention aims to render available a hair remover that is not only rigid and compactly proportioned to fit the hand of the user but shaped and proportioned to per-, form its hair removing and skin treating func tions over areas of the person not too easily reached by other devices.

The invention has for a further objective, a hair removing device constructed essentially of a stone or stone-like material especially treated for this particular purpose and by which the surface of the stone is roughened to present a multitude of infinitesimally small projections and intervening cavities suitable for abrading the hair when rubbed gently over the skin. As the stone wears away 'a new roughened surface continually presents itself thus rendering the device useful until too small to handle. By way of further improvement, the stone-like abrasive member may be further roughened by mechanical means to present for example, a ribbed effeet on one side for coarse work or toughened skin and a finer surface effect on another side for finer work or more delicate skin.

Still another aim of the invention is to provide such an abrasive element with a built-in or self-contained reservoir for a skin soothing liquid, which reservoir may be removed from time to time to replenish the supply. The reservoir itself, in accordance with this invention, will preferably be constructed as a hollow deformable tube closed at one end and corked at its other end. After filling the tube, the corked end will be inserted into the abrasive element and in cooperation with the abrasive element is arranged to function as a valve. tended that a sufiioient portion of the tube remain exposed and accessible for manipulation whereby the valve may be opened and closed at will. When the valve is in open position, a slight pressure on the exposed portion of the deformable tube will expel skin treating oil therefrom which flows through the interior of the abrading element through channels provided, to the operating surface thereof and to the skin of the user.

Other objects and advantages will be in part indicated in the following description and in part rendered apparent therefrom in connection with the annexed drawings.

To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed as a part of this disclosure and, in such drawings, like characters of reference denote corresponding parts throughout all the views, of which:

Figures 1, 2 and 3 of the drawings are respectively front, side, and plan views of an assembled device embodying the invention.

Figs. 4 and 5 are vertical sectional views of the device taken in transverse planes.

Fig. 6 is a view, partly in section, illustrating a variant form of valve.

Referring more particularly to Figs. 1, 2 and 3, a hair remover constructed in accordance with this invention, will comprise essentially, a shaped abrasive stone element It, having a built in reservoir ll. Preferably,'the stone will be cut so as to be wider than it is thick and somewhat elongated. The flatter sides Illa of the stone may be tapered and somewhat wedge-shape and the point end slightly rounded as at lib. If desired one or both of the flattened sides iDa may be grooved or ribbed, as at 180, to define and present the normal or inherent abrasive qualities of the stone in ridges with intervening valleys.

Within the body of the stone is formed a relatively deep cavity l2 that extends approximately half way the length of the stone (Figs. 4 and. 5).

It is in- I 3 The recess or cavity 12 is circular and in the form illustrated in Fig. 4, is formed with a flat bottom l3. Eccentric to the central axis of the cavity one or more passageways M are formed which lead from the interior of the cavity to the tapered exterior working surfaces of the stone. The relatively deep cavity I2 is adapted to receive the capsule or vial reservoir in containing a skin lotion. Preferably, the vial will be constructed of transparent material of a quality that is inert to the skin oil and also possess the property of being somewhat deformable. One end of the vial is closed, as at Ila, and the other end by means of a resilient cork l5, also made of material inert to the skin oil. The cork will have an external diameter I50, approximately the diameter of the cavity I2 in the stone so as to form an effective seal therewith, and a reduced portion Ib of a diameter closely fitting the open end of the vial I I. Also, the cork will be provided with a fluid passageway l5, extending generally parallel to the axis of the vial. The passageway may be offset from the axis of the bore in the stone by an amount corresponding to the eccentricity of the leading end of the channel or channels M in the stone. With the parts assembled and related as illustrated in Fig. 1, the outlet end of the passageway 16 is effectively closed by the stone end wall l3. However, when the vial is turned about its longitudinal axis, communication is established between the passageway l6 and with the leading end of the channels l4 in the stone. When the latter relations obtain a slight squeezing pressure upon the exposed portion of the vial will cause a portion of the contained liquid to be expelled through the passageway IG in the cork and through passageways I4 to the working face of the stone. Accordingly, as the stone is used, the skin lotion is worked into the skin of the user and prevents irritating effects. As more oil is required, the deformable reservoir is again lightly squeezed, and an additional quantity is supplied from the interior of the stone.

When the ports IS and I4 are in communication as above explained, the oil is prevented from leaking out of the cavity I2 by reason of the seal therewith made by the marginal portion of the vial cork. When the hair removing operation has been completed, the reservoir vial Iii is again rotated about its axis to close off communication between ports [6 and i4, and the port l6 again becomes sealed by the blank end wall l3 of the stone. As an additional assurance against leakage of oil, which is of special importance in a pocket device of this kind, the passageway [6 in the cork may be formed conical with the small end of the cone towards the supply. A cone shaped passage automatically breaks the tendency of the oil to flow by capillary action.

The device of Fig. 6 is similarly constructed with the exception that the stone engaging end of the cork 2D is formed with a cone shaped recess a thatfits over a complementally shaped projection 2| formed in the stone. In this construction the passageway 16a in the cork, leads to the apex of the male and female valve cones. In addition, the vial may have formed upon its exterior one or more convolutions of a helical thread 23, and likewise the receiving cavity in the stone will be threaded to match. In this variant form, rotation of the body of the vial causes relative axial movement to occur between the cones 28a and 2| and establishes communication or closes off communication between the passageways l6 and M. It is preferred that a 4 right handed thread be used, for it is natural for a person to turn a part clockwise to tighten or to close, and counterclockwise to loosen or to open.

In order to determine by sight the open or closed position of the ports I6 and 14, the vial may carry an index mark on its side such as a dot l1 and a zero mark such as a dot is may be applied to the stone. When the marks are opposite one another the flow channels will be understood to be open, and if not opposite one another it will be understood that the ports are closed.

From the foregoing it will be seen that a neat and compact hair remover of the abrading character is provided. One that is easy to use on various irregular areas of the person, one that carries within the abrasive element its own reservoir of sooth ng oil which in coaction with the stone itself, is arranged to function as a valve and a pump operative to discharge small quantitles of a skin oil from the interior of the stone to its exterior working surface and thence directly to the skin of the user. The construction and operation of the valve is simple and without complications, and when closed by a simple and natural turning movement effectively seals off the fiow and prevents leakage or loss of fluid that would, if it did occur, be quite aggravating.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can, by applying current knowledge, readily adapt it for various utilizations by retaining one or more of the features that, from the standpoint of the prior art, fairly constitute essential characteristics of either the generic or specific aspects of this invention, and therefore, such adaptations should be, and are intended to be, comprehended within the meaning and range of equivalency of the following claims:
