PLIER WRENCI-I.

Application vtiled. July 9, 1924. Serial No. 724,993.

To all whom it may concern.'

Be it known that I, ALEXANDER Canton- SHANK, citizen of the lominion of Canada, residing at Matsq ui, in the Fre-vince oi British Columbia, Canada, have invented certain new and useful Improvements in Plier llfrenches, ot' which the following is a speciication.

This invention relates to a plier' nut wrench having provision for obtaining a flat bearing of one of the jaws of the plier on a plane of the nut to which it is applied and :tor securing the jaws in the desired position of opening.

The invention is fully described in the Jfollowing specification, referencevbeing made to the drawings bywhich it is accompanied, in which:

Fig. 1 is a face view of the wrench complete.

Fig. 2, an edge View of onelo the handled jaw members, being on the line 2-2 in Fig. 1.

Fig. 3 is a cross section to an enlarged scale on-the line 3-3 in Fig. 1, and

Fig. 4 is a similar view of a modiiied form of pivotal connection.

In these drawings 2, 3; 4, 5 represent the opposed plier members which are pivotally connected together by a pin 6 having a customary provision for varying the jaw opening of the plier.

To one of the jaw members 3, ajacent its vouter end, a member 7 is pivotally connected at S to its inner side to have a limited rocking movement in relation to the acting face oi: that jaw. The member`7 may, as shown in Fig. 3, have a divided bearing on the jaw member, or, as shown in Fig. 4, may have its bearing all on one side.

The pin 8 is relatively a loose lit in the member 7 and in the jaw to which it is connected to permit the outer edge of the pivotal eye of the member 7 to take its bearing at 15 direct on the jaw, whereby the pin 8 is relieved of the strain, and a fuller area is afforded to endwise wear.

Vhen this device is applied to a nut, instead of the jaw member 3 making contact with the nut at oneplace, either adjacent the point or adjacent the pivot 6, according to the amount of opening of the wrench, the

member 7 adapts itself to the plane ot the nut and takes a uniform bearing thereon whereby injury to the nut is avoided and a more effect-ive hold is attached. Y

The pivoted member 7 may have a lengthwise V-groove 9 to enablea wire or pin to be effectively held. l n

A small handled lever 12 is pivotally mounted at 10 on the inner side of one handle member 2 of the pliers adjacent the other handle member 4. The handled lever 12 has an eccentric portion 11 around the pivot 10, on which eccentric portion fits the eye of a pawl 13 which'engages any one of a series of notches 14 formed on the lever member 4 adjacent thereto.

It the eccentric 11 is turned to the position indicated by the dot and dash lines, the pawl 13 is free to turn on the eccentric 11, and may be withdrawn from its engagement with the jaw member 5, but when the eccentric is turned to the positionl shown by full lines in Fig. 1, the strap of the pawl is pressed against the handled jaw member 4,

5, the pawl is retained in the set position of retaining engagement by the Wedging action gf the eccentric against the handle memer 4.

In use, the pliers are largely adjusted on their pin 6 to the size of the nut, and the ratchet pawl 13 is released to turn freely on its pin by movement of the eccentric extension 12 to the position shown by dot and dash lines. The pliers are then gripped in the hand to tightly close the jaws 3,` 5 on the nut and by the thumb ofA the gripping hand the pawl13 is then moved into engagement with one of the notches 14 and again with the thumb the extension 12 Vis moved against the handle to tighten the eccentric and. retain the pawl in the adjusted position. The device ormsa simple and inexpensive addition to an existing form of Wrench and renders its use more satisfactory in the manner explained. j i

Having now particularly described my invention, I hereby declare that what I claim as'new and desire to be protected in by Letters Patent,`is:

1. In a plier wrench, a Hat faced member having arcuate bearing ears mounted in arcuate bearing recesses on the inner side of v 'one of the jaws to have a limited rocking movement about an axis parallel to that of the hinge pin of the plier members, means holding said flat faced member in place, and means 'for securing the jaw members in an adjusted position against movement outward therefrom, said means comprising a pawl and ratchet connection between said levers and a shii'table eccentric on which the paWl is mounted.

2. In a plier Wrench having crossed handies pivoted together7 means for holding the Wrench closed on an object, said means comprising a paWl and ratchet device which includes a lever pivoted to one handle member and having an eccentric bearing portion and a paWl having an eye mo-unted on said eccentric bearing por-tion, said lever being mounted adjacent to the handle of the opposing plier member whereby when said lever is moved on its pivol to bring said pavvl into engagement with the ratchet, the eccentric will be moved toward the plier' handle into holding engagement therewith, substantially as shown and described,

3. A plier Wrench comprising crossed levers pivoted together, a small lever pivotally mounted on one of the crossed levers and having an eccentric around the pivot, and a paWl mounted on the eccentric of the small lever and adapted to engage notches on the other crossed lever, substantially as specified.

ln testimony whereof l aliix my signature.

ALEXANDER CRUCKSHANK.
