For example, this movement is approximately 0(0.18 Iinch. "Thus, 'the sleeve Will `be urged into the hair gripping-position f by a resilient actionibutwill ybe'nioved tothe hair re- -leasingpostionlby a ipositivevaction. 4It Will be 3 understood that the sleeve will be moved in opposite directions once during each revolution thereof.
As the extractor is operated, there will be a tendency for dirt and the like to work outwardly along the rod 6 and appear between the end of the sleeve l and face IU where it would be transferred to the skin by the user, which is of course undesirable. The groove i2 catches and retains this dirt and other material before it enters the space between the sleeve end and face I0. Thus, this dirt, which may be of a greasy consistency, will be arrested before it is smeared or deposited on the skin of the user.
Also, bits of hair, dry skin and the like are apt to collect between the face I and the end edge 3.2 of the sleeve 'l and interfere with eflicient operation of the extractor. In order to permit easy removal of the material collected between the hair gripping surfaces i0 and 32 and to clean out the groove periodically, I have provided manually operable means for retracting the sleeve beyond the groove so that a cloth or cleaning tissue may be inserted between these surfaces and into the groove as the sleeve and rod rotate. This means comprises a flange 41 formed on the stop member 44 and an eccentric actuator for engaging the flange and moving the member 44, together with the sleeve l, to the left. The eccentric actuator consists of a cylindrical plug 49 rotatably mounted in an opening in the handle 5. The inner face of the plug 49 has a roller 50 mounted thereon eccentric to the axis of rotation of the plug so that when the plug is in the position shown in Fig. 1, the roller is out of contact with the flange 41, but when the plug 49 is rotated through 180, as shown in Fig. 2, the roller 50 will engage the flange and move the member 44 out of contact with cam 34 and cause the outer end of the sleeve 'l to move to a position in which the groove l2 is uncovered. For example, the edge 32 may be separated 11g from face l0. This retraction of the sleeve may be effected while the rod and sleeve are rotated and by merely inserting a cloth or tissue between the surfaces ill and 32 and into the groove, the dirt will be removed, assisted by rotation of the rod and sleeve.
The plug 4@ is provided with a dial. portion V52 by which 'the plug may be rotated manuali", and the plug is retained in its opening by a ball 54 being urged into sockets 55 formed at 180 to one another. The ball 54 is pressed by a spring 5E compressed by a threaded plug 51. Preferably, the dial is provided with indicia which cooperate with a mark 50 on the handle to indicate the operative position of the dial. For example, an O may be provided near the edge of the dial which when registering with mark 60 indicates that the faces I0 and 32 are separated for cleaning. An -arrow may be provided on the opposite side of the dial to indicate the normal operating position.
By my invention, I have provided a power driven hair extractor that will not smear or soil the skin of the operator and which may be quickly cleaned with a minimum of eifort.
Although I have described but one form of the invention, it is to be understood that other forms might be adopted, all falling within the scope of the claims which follow.
1. A hair extractor comprising a handle, hair gripping elements carried by the handle and extending from one end thereof, one of said elements consisting of a rod having a laterally projecting face at the end thereof and the other of said elements consisting of a sleeve surrounding said one element, said elements being rotatable about a common longitudinal axis; means for reciprocating one of said elements along said axis relative to the other element during rotation of said elements whereby hair is gripped and released from between the end of said sleeve and said face; and manually operable means for moving said sleeve longitudinally relative to the other member during rotation of said elements for maintaining the end of the sleeve and said face separated and inoperative to grip hair, said manual movement of said sleeve being greater in degree than the movement during reciprocation by the rst mentioned means.
