TWEEZERS .Filed Dec. 29, 1930 IIIII i ii Patented Jan. 12, 1932 PATENT OFFICE UNITED STATES RICHARD BESOCKE, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ARCHKING CORPORATION, A CORPORATION OF ILLINOIS TWEEZERS Application filed December 29, 1930. Serial No. 505,431.

This invention relates to tweezers especially adapted for the removal of superfluous hair or the" extraction of hair of the eyebrows, or where desirable to remove superfluous or unsightly hair growths. QAn object of the invention is the provision of an improved device of the character indicated, by means of which ready and 6f? fective access is had to the particular hair desired to be removed, and by means of which a firm and substantial holding or engaging action of'the device on the engaged hair is attained. A further object is the provision of an improved hair engaging tweezer characterized by a pair of cooperating resilient disk engaging members adapted to provide a peripheral engaging area and constructed and arranged to insure engaging contact throughout the peripheral engaging portion; Other objects will appear hereinafter. The invention consists in the combinatio'ns and arrangements ofparts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a partof this specification, and in which: i

Fig. 1 is an enlarged side elevational view illustrating the preferred embodiment of the invention, with the disk members in disengaged position;

Fig. 2 is a view similar to Fig. 1 showing the disk members in engaged position;

Fig. 3 is a front elevational viewof the device as shown in Fig. 2;

Fig. l is a top plan view of thedevice as shown in Fig. 1, taken substantially on the line 44 of Fig. 1; i

Fig. 5 is a vertically sectional view taken substantially on the line 55 of Fig. 2;

Fig. 6 is a cross-sectional view taken on the line 66 of Fig. 5;

Fig. 7 is a sectional view of the operating link portion taken substantially on the line Fig. 8 is a view similar to Fig. 7, taken substantially on the line 8-8 of Fig. 3;

Fig. 9 is an elevational view, partly in section, of a modified form of device in which the engaging disks are notched to provide hair engaging or gripping corners; and

Fig. 10 isa sectional view taken substan tially on the line 101O of Fig. 9.

As illustratedin the drawings, the preferred embodiment of the invention disclosed comprises a stationary aw 12 integrally formed at one end of a straight stem or rod 13, which is threaded into, or otherwise secured to, a handle member 14. As shown in the various views, the contacting margin of the stationary aw 12 is preferably in right angle relation to the stem 13. Asecond jaw 15 is mounted for cooperative engagement with the jaw 12, and is preferably formed integrally with a sleeve extension 16 arranged for sliding movement on the stem or rod 13. In addition, each jaw 12 and 15 is of cupped formation, as shown in Fig. 5, and sufficient clearance is provided between the stem 13 and the inner surface of the sleeve 16 to insure contacting engagement of the pe ripheral edges of the j aw members, as shown in Fig. 5.

The jaw members 12 and 15 are normally maintained spaced apart in a yielding mannerby a compression spring 17 encircling the stem or rod 13 and arranged between the jaws, as shown in Fig. 5. In the preferred construction, the lower portion of the spring 17 rests in a socketed enlargement 18 of the sleeve extension 16 on the movable jaw 15, with a view to the provision of sufficient length in the spring, and also to provide uniform and adequate resiliency when in active use.

The sliding action on the movable jaw to bring the members into operative con tact or engagement, is preferably attained by the following construction. A pair of links 19 and 20 are pivotally connected together by means of'a narrowed tongue portion 21 on the lower link extending vertically through opening 22 provided on the laterally extending portion 23 of the upper link 19. Thus, the links'19 and 20 provide a toggle unit with the upper free extremity of link 19 formed with an eye 24 encircling and sliding upon the stem or rod 13, and having bearing against thelower extremity of guide sleeve 16 of the movable jaw 15, in orderto impart positive movement of the latter toward the stationary jaw 12 in actual use: The lower extremity of the companion link 20 is also provided with an eyeencircling a rivet member 25' extendingf throughtthe eye oi link 20 and also througl'ra corresponding eye formed in the handle 14. This mounting pros vides a pivotal connection between the toggle link and the handle 14,. but, as shown;

in Fig. 1, a slight clearanceis provided .between the respective parts and the rivet 25 so as to allow free movement and eliminate any binding action.

In the modified form of construction. shown in- Figs. 9 and'10,} the engaging disks are provided with registering notches 26 which provide sharp corners 27 in spaced relation, with each pair of corners adapted to aid in a-ready select-ion of,-'and engagement with a hair to be removed. A; guide member 28 is-secured to the upper disk 12 and extends through a slot :in disk '15 to maintain the corners 27 in vertical alignment,

- In use, the device orinstrument may be heldin thehand, with the fingers bearing against the handle member 14, and the thumb in contact with the tongue portion 21. Whenthe respective disk j aws12 and'15 havebeen positioned on opposite sides of a hair to A be removed, the toggle unit-is straightened by compression of the fingers to the posi{ 7 tion shown in Fig. 2-, causing a corresponding active movement ofthe movable jaw 15 .1nto gripping" relation with the stationary j W12.- Theslight resiliency of the jaw members, together-"with their cupped construction, insures peripheral contact upon engagement, and this operation is also aided by the clearance between the sleeve member 16 and the stem 13. 'Theform'shownin Figs. 9 and 10' ail-ords an accurate andselectiveengagement when it is desired to remove a single hair, for example, when apair-of the corner-s27 may be brought into engaging position.

While I have illustrated'and describedth'e preferred form of construction for carrying my invention into efi ect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth,'but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
