To @ZZ whom it may concern:

Be it known that I, JOHN SEMO, a citizen of the United States, residing at Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Combination lmplements, of which the following is a specification.

This invention relates to pliers of the type equipped with cutting jaws, the invention having for its object both to provide a novel arrangement of the cutting jaws and also to construct the main jaws to form a hammer. A further object is to provide a novel form of leverage adjustment.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a side view of a pair of pliers constructed according to the invention,

Fig. 2 is a top edge view thereof,

Fig. 3 is a transverse section on the line 3 3 of Fig. 1,

Fig. 4: is a fragmentary horizontal section on the line P-1 of Fig. 1, the nut 18 being indicated by a dot and dash line,

Fig. 5 is a detail transverse section on the line 5-5 of Fig. 1 and showing the pivot adjustment bushings extending transversely of the pliers, as in Fig. 1, and

Fig. 6 is a fragmentary side eleva-tion showing the pivot forming portion of one of the jaws. As here shown my improved pliers comprise a pair of jaw members 10 and 11 pivotally attached to one another and having handle extensions 10 and 11 respectively. rFliese jaws may have roughened gripping faces 12, The handle 10 is preferably pointed at its free end as at 10a while the handle 11 has a screw-driver element 11a formed on its free end.

The jaw 10 is formed on the side opposite its gripping face with a hammer head proj ection 13 while the jaw 11 is formed with a claw extension 14.

The jaw 11 carries an adjustable cutting blade 15 which is preferably of rectangular 1921. Serial No. ll''.r

shape as seen in face view `and ywhich is guided in a recess 16 in the said jaw. To 55 adjust this blade 15 a screw 17 is fixed to the rear edge thereof and entends freely through a suitable boring in the jaw 11. This screw is engaged by a nut 18 held against axial movement in a suitable recess extending inwardly from the side of the jaw, the nut projecting out of said recess on one side as shown to be engaged by the thumb or finger for turning, the nut being here shown as of circular form with a'ltnurled 65 edge. A fixed cutting element 19 is formed on the jaw 10 to co-operate with knife 15, the jaw 10 being recessed adjacent this fixed cutting element to receive the knife.

To provide for variation of the jaw leverage, that is to say for adjustment of the pivot point of the jaws nearer to or farther from their working faces, each jaw is provided with a cruciforin slot 22, one branch of which extends longitudinally of the jaw, and the other branch transversely thereto. 1n these slots are carried freely a pair of oblong bushings `23 adapted to t snugly in either of the respective longitudinal and transverse branches of the slots, and which have each an aperture 24 therethrough, said aperture being located nearer one end of the bushing than the other. A headed pin 25 passes through these bushings 23 and has a nut screwed on its other end. The bushings are held against inward movement by means of seat elements 26 on the ends of the slots at the inner sides of the jaws.

As will be apparent, the fulcrum point can be adjusted to three different positions with the above construction by shifting the bushings 23. When the bushings are arranged in the longitudinal branches of slots 22 with'their apertures 24 toward the working faces of the jaws the leverage will be greatest as will be obvious, while the leverage will be least when the bushings are reversed in these longitudinal branches of the slots. By placing the bushings in the transverse branches of the slots an intermediate leverage is obtained The knife 15 may be adjusted as desired according to the Work to be done, being preferably drawn in as close as possible to the face ofthe jaw 11 when small hard articles, 105 such as piano wires, are to be cut. This arrangeinentalso permits of the knife being used in scoring or marking surfaces different depths.

As will be apparent, I have provided a simple and handy combination tool 1which may be used eieientiy for a number of purposes.

I-Iaving thus described my invention, what I claim as new and desire to protect byLetters Patent oi the United States is as'ollows l. In a tool of the dass described', avpair of jaws having eruoiform slots therein,r a pair of bushings fitting in said slots and signature. A

JOHN SVENIO.
