COMBINATION-TOOL.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed May 15, 1919. Serial No. 297,365.

cisco and State of California, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specification.

The present invention relates to improvements particularly in the construction of the article set forth in our issued Letters Patent of the United States No. 1,268,558 granted to us June 4t, 1918.

The present invention is designed more Particularly for use as a medical or manicuring implement, it being designed to include a pair of tweezers and a knife or cutting member preferablyprovided with a pricking implement designed for opening the flesh when splinters or other foreign matters are embedded therein, to enable the same to be readily removed by the tweezers, although the cutting member is adapted for use generally where cutting members are required and the tweezers are equally as well adapted for use where tweezers are generally employed.

The principal object of the present invention is to simplify the construction of the implement case or frame, the tweezers and the manner of mounting the same within the case, whereby the cost of manufacture of the article is considerably reduced over that set forth in our prior patent.

In the present construction the tweezers are constructed in two parts, which are duplicates, and which, when assembled, are reversed, they being united to pivot together through the pivot pin which provides their fulcrum in the case, and to which the tweezer forming members are secured through a polygonal connection.

With the above-mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size, and minor details of construc tion within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In order to comprehend the invention, reference is directed to the accompanying drawings, wherein the various parts are disposed in disassembled relation to more clearly present the construction and arrangement thereof.

Figure 1 is. a view in perspective of the knife or cutting member, Fig. 2 is a corre sponding view of the tweezer forming members, Fig. 8 is a similar view of the polygonal pivot pin, and Fig. 4 is a like view of the case.

Referring more particularly to the drawlngs, whereln like characters of reference designate corresponding parts, the imple-- ment case or frame is indicated generally by the numeral 1 and the same consists of a one-piece member having upwardly bent sides providing a trough-shaped construction, the sides of the casing being at one end pressed or forced into contact and formed with an aperture or opening 2 to facilitate the article to be readily attached to a key ring or other suitable carrying member. The side members at the other end of the frame are brought close together, thereby providing a case or frame, the side walls adjacent the center thereof being outwardly bowed as in the drawings. The back wall of the casing adjacent the end where the side wall members are slightly spaced from each other terminates flush with the corre sponding ends of said side walls, as at 3, Fig. 4 of the drawings, and said side walls are provided at said casing end with a circular opening 4 for the reception of a pivot pin. The tweezers in the present construc tion are formed of duplicate spring members 6 capable at their free ends of reception within the bowed portion of the frame, and at their opposite ends said members are provided with a polygonal opening 7 through which extends the polygonal pivot pin 8 which unites said corresponding ends of the tweezer-forming members, and the opposite ends of said pivot pin are fulcrumed in the circular openings 4 in the casing 1, thereby providing a fulcrum for the tweezers and insuring a uniform swinging movement of the tweezer-forming members. The tweezerforming members when in their extended position, that is when the free ends swing from within the case, are adapted to contact adjacent their fulcrum end with the rear wall portion 3 of the casing which provides a support therefor.

Between the two tweezer-forming members 6 is positioned a suitable knife or cut ting member 9, the free end of which is provided with a pricking member or point 10, which is capable of being used as a probe, the opposite end of said knife being provided with a circular opening 10 through which passes the polygonal portion of the pivot pin 8, said pin providing a fulcrum for the knife and enabling the free endof the same to be swung or pivoted on the pin 8 independently of the movement of the tweezers.

The back of the knife or blade 9, near the fulcrum'point thereof, is cut away or recessed to form a shoulder 11 which also contacts with the portion 3 of the frame back wall when the blade is swung on its pivot and in operative position, said blade being supported with its back wall substantially in alinement with the back wall of the casing. Thus it will be apparent that both the tweezers and the blade rest, when extended their full limit, on the back wall 3 of the casing.

To facilitate the easy opening of either the tweezers or the blade, the casing is provided with the finger reception recesses 12 above which lies the nail-receiving groove 13 formed in one of the tweezer members; and the blade is provided with an upstanding or raised portion 14, which, when the blade is in closed position, extends upwardly from the upper edge of the side walls there of, said portion being also provided with a nail-receiving groove 15.

It will be apparent by our present construction that the cost ofmanufacture of the implement disclosed is considerably less than that illustrated in our former patent, inasmuch as the tweezer members being formed in duplicate halves united through the pivot pin enables short ends of material to be employed, and also enables the employ ment of a single die in the formation of said half members, which members are duplicates when disassembled and in mounting the same they are reversed to arrange the bowed portions 16 thereof to extend toward the op osite sides of the casing wall.

aving thus described our invention what we claim as new and desire to protect by Letters Patent is A device of the class described comprising a casing formed of a single sheet of metal bent to provide a frame having integral side and back walls and open along one edge, the side walls thereof adjacent one end being formed with alined pivot-pinfreceiving openings and the back wall adjacent said end terminating flush with the ends of the side walls, a pivot pin extending through said openings and fulcrumed at its opposite ends in said respective openings, a portion of said pin being polygonal in cross-section, a pair of independent tweezer members capable of reception in said case, said tweezer members being provided adjacent one end with alined polygonal openings for receiving the polygonal portion of said pivot pin and being united together thereby to pivot as a unit with said pin, and a blade receivable within said casing between said tweezerforming members and fulcrumed at one end on said pivot pin to swing independently thereof, the back of said blade, adjacent said fulcrum, adapted to contact with said back wall and be limited thereby when said blade is in its full open position.

In testimony whereof we have signed our names to this specification in the presence of a subscribing witness.
