Referring to the drawings in detail, th'ereference character 5 designates the shankof the stationary jaw, which hasV one end thereof v.

Wide, `and :isi vpro-*- videctflwithfpivot openingsi 8 adapted `,to` aline' Witnthe 'openings-.1Si-forniedein thelin'ner endv of yoke I5, to the end that by rotating the securing rod in one direction, the movable jaw mayv j,

be moved'into close engagement with the object over which the jaws have been positioned1 thereby insuring against the Wrench slipping, when.

excessive strain is brought to bear thereon in moving the object.

The reference character I9 designates the pivotpin of the wrench that connects the lever Ill with the shank 5. The pivot pin is formed with an annular groove at one end thereof, which groove is adapted to -be engaged by the spring iingers y2l), which snap into place within lthe.

. itwill be obvious `that by removing the pin and formed into a handle 6, the opposite end being formed into a jaw portion 1 which is extended at an oblique angle with respect to the shank 5,

, placing it in other aliningv openings, the initial movement of the movablejaw lwith respect to the stationary jaw may be adjusted quickly and accurately. It should be obvious that after the adjustment has been made in this way, theoperation of the` rod Il willI` act to move the movable jaw into close engagement with the ob,-

ject, making the final adjustment so that the jaws of the Wrench will securely grip the object.

The chain indicated at 2| is providedior securing the pin I9 to the'wrench to insure against lossvof the pin.

, and'is provided with an elongated openingvin pinr 28 beingcar-f fried by the lever 26.

vFrom the foregoing detailed disclosure, it is believed that the operation of the plier type Wrench will be obvious, and that further description as to the operation of the wrench is unnecessary.

In the form of the invention as shown by Figl ure 6 of the drawings, the shank of the wrench, which is indicated by the reference character 22, is formed with an elongated opening iny which the block 23 operates. y The block v23 isformed with laterallyextended trunnions 24 thatlmove-inopenings formed in the flanges 25 of the. lever 26. The movable jaw in this form of the inven y,

1. In a quick actingwrench, a stationary jaw comprising a shank and a handle, amovable jaw including a yoke, slidable over the shank ofthe stationary jaw, a lever pivotally and slidably connected with the yoke of the movable javv and being pivotally connected with the handle ofthe stationary jaw, said lever adaptedto be gripped With the handle ofthe stationary jaw in oper-v ating the movable jaw, a shoulder extending.

rearwardly from the yoke," adjacent ,to the rear edge thereof, and an"vadj,u s'tabl e threaded rod extending through the lever and adapted to engage said shoulder restricting movement of said movable jaw in one direction.

l' 2.'In a quick acting Wrench, a stationary jaw comprising a shank and a handle, a movable jaw An adjusting screw 29 is provided, wl'iichscrewfA fI-"z operates on the threaded portion of the rod 30,

`that is swiveled to the block 23, to the end that by rotating the adjusting,screw` 29 the pivotl point betweenv the lever 26and movable ljawsmay be varied, to adjust the movable jaw with .respecttothestationary jaw 29 and adaptY the awrench; for'.y positioning on varied sized, articles.
