To all whom it may concern: 7

Be it known that I, WVILLIAM BRYCE, a citizen of the United States, residing at Saltillo, in the county of Hopkins and $tate of Texas, have invented new and useful Improvements in Pliers, of which the following is a specification.

The present invention relates to improvements in pliers, primarily adapted for use by linemen in securing an electric conducting wire upon an insulator, splicing the wire or stretching the same, and the primary object of the invention is to simplify and improve the existing art by producing a pair of pliers which are simple in construction, cheap to manufacture, and which will perform the functions of several ordinary tools.

With the above objects in view, and others which will appear as the nature of the invention is more fully understood, the improvement resides in the novel construction, combination and operative arrangement ofparts set forth in the following descriptionand falling within the scope of the appended claim.

In the drawing there is illustrated a simple and satisfactory reduction of the improvement to practice, and in which: I

Figure 1 is a perspective view of a pair of pliers constructed in. accordance with the present invention, the jaws being closed, Fig.

2 is a similar view illustrating the pliers suspended from a line wire support preparatory to the application of a splice wire thereto, 1

Fig. 3 is a view illustrating the manner inwhich the splice wire 18 secured upon the line wire by my improved pliers,-'Fig. i is a view illustrating the manner in which a (1011- I ble splice is made by my improved pliers, Fig. 5 is a view illustrating the manner in which a splice or tie wire is secured, upon a line wire to retain the line wire upon an insulator, Fig. 6 is a perspective view of one of the members of the pliers, Fig. 7 is a transverse sectional view approximately on 6, Fig. 8 is a horizontal the line az-0e of Fig. sectional. view upon the line g 'y of Fig. 7, and Fig. 9 is a detail sectional view illustrating the manner in which the locking bar 4 engages with the reduced end 3 of one of the handles 2 to secure the said handles in locked position.

The pliers, generally designated by the numeral 1, comprises a pair of members includa handle 2 and a jaw 3. The jaw from the handle in the usual man ner, and the members are pivotally connected at the said ofiset portions, so that when the handles are swung toward each other the jaws will have their inner faces contacting. lChe end of one ofthe handles 2 is provided with a reduced stud or extension 3 while the end of the second jaw has pivotally secured thereto a bail or looking bar l, the said bar havingits free end provided with an opening 5 to engagewith the stud 3 to se-' curely lock the pliers in closed position. It

is to be understood that the handles being formed of metal embody a certain degree of natural resiliency, and a slight compression between the ends of tlie'handle members is required in looking the-member t upon the stud 3, the expansion of the handles causing a tight frictional. engagement between the stud 3 and the wall of the opening 5, so that the niember cannot become accidentally disengaged from the stud 3". By reference to the drawing it will'be'noted that the'member4 has its pivoted end provided with ears which are arranged in depressions upon the inner face of the end of the handle member to which it is attached, and also thatthe end of the said member provided with the opening 5 does not project beyond the sides or ends of the handle 2. This arrangement is essential inasmuch as the locking'means will. not interfere with the proper working of the instrumentwhen the same is suspended upon the wire, as illustrated in Fig. 2.

The inner faces ofthe 8," at their roughened, and thesaid inner faces, to the rear of the said serrated portions areeacli thatthe line wireis received when the deforward ends are preferably serrated or vice is in operation. The inner faces of I the jaws, to the rear of their openings 6, and forward of their pivotal connectionare each provided with a semi-circular depression 7 which is ofa'l'arger area than thatof the openings 6, the said openings 7 terminating in an angular wall 8, the outer edge of which being preferably sharpened, and these sharpened edges are adapted to serve as cutting or severing elements, as well as means whereby an insulation may be removed from an ordinarycovered wire, when the pliers are employed on inside electric work.

Integrally formed upon one of the sides or faces of each of the jaws 3 i a laterally extending lug or ear 9, the same being disposed diametrically opposite the openings 6, that is, the said ear has a depressed portion 10 which almost entirely surrounds the opening. Each of the ears, to one side of the portion 10 is continued at an angle to the outer face of the jaw as indicated by the numeral 11, and it will be noted that the portion ll, upon one of the jaws, is directed toward the handle end of the wrench, while the portion 11 upon the opposite jaw 3 is directed toward the outer side as well as toward the end of the said jaw. The members 11 have their lower faces concaved, as indicated by the numerals 12, the said concavities gradually increasing in width from the inner end to the outer end of portion 11 of the said ears. The ends of the ears 9 opposite that provided by the beveled or inclined portion 11 are arranged at a right angle with respect to the inner longitudinal faces of the jaws 8, as designated by the numerals 13, and the inner terminals of the said ends 13 provide straight walls or shoulders 14- which are flush with the inner faces of the jaws.

The upper edges of the rounded Walls provided by the grooves or wire guides 12 are rounded, as is the inner wall of each of the said grooves at its juncture with the de pression 10, and likewise the end walls of the openings 6 are rounded, so that no abrupt surfaces are presented whereby the galvanizing might be removed from the wires engaged by the tool or otherwise injuring them so that the iron from which thewire is constructed would be exposed to the weather and subjected to rust and disintegration.

In operating the pliers to apply a splice thereto, as illustrated in Fig. 3, the jaws are opened to receive the wire and are then closed by the lock 4: to hold the pliers suspended as shown in Fig. 2. The ears 9 crimp or compress the splice and line wires at the points A. The tool is then rotated around the line Wire B, and the engagement of one of the jaws with the splice wire C causes the same to be looped or wrapped around the line wire B as indicated by the character As many loops D may be provided as desired. When the tool is employed to provide the splice illustrated in Fig. 4:, the same has its ears forced against the two line wires and the splice wire to crimp or compress the same at the points F and the end of one of the line Wires as well as the splice wire is coiled around the second line wire as indicated by the character G.

in Fig. 5 the line wire i arranged to contact with one of the sides of an insulator l and the tie wire is secured to the same by being coiled upon the ends or portions of the line wire on opposite sides of the insulator, the portion of the tie wire between the coils being forced into contact with the insulator on the opposite side thereof from that engaged or contacted by the line wire.

From the above description, taken in connection with the accompanying drawing, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is:

In a pliers for the purpose set forth, two pivoted members comprising each a handle and a jaw, means for locking the handles for retaining the inner faces of the jaws in contacting relation, each of the jaws having its inner face provided with a registering semi-circular opening and the said faces of the jaws being rounded to the depressions, lug formed upon the jaws disposed opposite the openings, each of said lugs having one of its ends arranged flush with the in ner face of the jaws, each of said lugs having its inner face provided with a rounded depression which is disposed angularly with relation to the center of the registering openings, the said lugs being continued angularly from the depressions and the said angular Walls being concaved from their connection with the jaws, and the said concavities increasing in width from the walls of the depressed portions of the lugs.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM D. BRYCE.
