Heretofore, the generally accepted design the aw members A and C will move in uniof pliers in use has consisted of two jaw son. members having a head portion and a reln operation, when pressure is applied to 80 duced shank or handle portion, the two the handle portion 3 of the members A and members being piroted together so that the B, the heads 2 will move toward each other cutting edges of the heads will meet to cut and the head 6 of member C will move the wire. rilhis construction of plier is with the head 2 of member A until it clamps simple, cheap to manufacture, and very duagainst the wire being cut.

the jaw inen'ibers B and lD will move in unison.

The operation ol the fourth jaw l) is sul stantially the same as the jaw C. That is, the clampinglfac'e lat oiI the head ll will move with the head 2 of member l until it clamps the wire to be out against the head 2 ol" the jaw member A, where it will remain stationary while head 2 of member l will continue to move until the edges ol.l the cutting 'fares l meet and cut the wire. The continued movement oil the head 2 of member B is taken Vup in the springv shank oi inen'iber D. which will bow or give, suilieiently to allow the edges ol the cutting` faces to meet.

It will thus be seen that l have provided a pliers 'having positive elarfipingv means for Clamping both ends of Wire to be Cut prior to the cutting thereotthereby positively preverntingv the springing away or flying of the eut ends.

I claim:-

l. Pliers for Cutting,` Wire and the like, comprising in Combination, e pair ot' Cutting jaw members, each of seid members having` a head portion and a handle portion, said head portion being offset from the horizontal axis olf the handle portion to provide leverage and being; ln'ovided with a beveled fece, :L pivot passing' through said head portionsl to hold said jaw members together, a pair o'l clamping,` jaws mounted on said pivot, each ol" said last named jaws having a head portion and a flexible spring` shank portion, said shank portion being secured intermediate the ends Vo'l'the handle portion ot' one oi said cutting' jaws and movable therewith, and seid head portion being substantially the same thiekness throughout its length, and being' adapted to bear against the cutting face of the other Cuttingv javv, thereby holding the ends ot the out Wire.

2. Pliers for cutting wire and the like, (.-oniprising` in combination, a pair of cutting aw members, eaoh olf said members having a head portion and a handle portion, said head portion being ol'lset from the horizontal axis of the handle portion to provide leverage and being` provided With beveled cutting aee, a pivot passing' through said head portions to hold lsaid jaw members to- `gether, ay pair of Clamping jaws mounted on said pivot, eeeh of said last named jaws having` a heed portion and a flexible springV shank portion, said head portion being of less thickness than the head portion of said cutting Jaws, and said shank portion being` `secured intermediate the ends of the handleI portion ol one of said cutting jaws and movable therewith, said head portion being substantially the seme thickness throughout its length and being odset with relation to the longitudinal axis ol the Clamping javv so as to Fit around the head portion and bear against the cutting hice of the other cutting jaw, thereby holding the ends of the out wire.

Vin testimony whereof, l have hereunto si gned my name.
