The shank 1;.is provided with teeth 2 uponone'edge and isconstructed at one end Witha lateral offset 43 constituting the fixed jaw; The movable jaw 4 is disposed parallel with thedixed jaw and is constructed with side plates or wings 5 which extend longitudinally4 ofthe shankand are con-v y nected at their-lends by Webs 6. Said webs pass across the edges of vthe shank and thereby hold the jaw to the shank and-'gulcle degrees `to the shank and, therefore., when a hexagonal nut'4 is being turned, rthe nut will berengaged :on three sides. so that it willibe very rel'ectu'allvheld. The jaws may be smooth-faced, lof coursebut are shown as equipped with facing lates or gripping members7 which may e constructed with transverse teeth 8 so that a pipeor rod may aref removable and may be renewed from timeto ,time while the other portions, ofithe tool may be madeof cheaper material and the cost ofy manufacture thereby lessened. Iihe jaws are Constructed with longitudinal WRENCH.

grooves or seats which receive longitudinal ribs 9 on the respective pipe-gripping mem*-Y bers;` Theseribs and seats are oi' such crosssectional form that movement of agrippingv member away fromits jaw cannot occur and accidental" longitudinal movement j of l the member isprevented by a transverse retaining pin 10 insertedthrough the jaw and the rib, as shown clearly in Fig. `7. It willalso be noted that the side edges of thegripping members have a dovetailed engagement 1l with the jaws so that relative movement of the parts is in of theedges avoided.

' shank remote from the jaws, the side plates- 5 are constructed with hook-like extensions 12 connected by a transverse web 13 ofan arcuate` overhanging form thereby I providing a seat for the convex end or` fu1crum14 of the lever 15, thefree end of the le-.ver being provided with a longitudinal reinforcing rib 16 on its innerside. Near its ulcrum, the lever is provided with ,the guards 17 which dependat thesides of `theshank and` prevent lateralmovement of the leverrelative to the` shank. To accommodate these guards, the edges of the -side plates 5 arerecessed, as shown at 18,-and in the ends of the side plates are circular notches or seats 19 in which" are rockingly engaged and yheld the knobs or disks 2O on the edges of a releasing cap 21. The ysaid cap fits over the shank and is provided with afinger 22 extending between the guards 17 and engaging under a lip 23`onthe holding'dog 24, the guards constituting ahousing for said dog'. Thel dog'24, at the end remote from the lip 23, is

- 27 which is tted ,within aurecess 28I yin the lever and retained therein by atransverse pin, 29 as shown and as` will be readily understood. The under edge ofthe dog 24 is provided with teeth BOadapted to engage with the teeth 2 on the shank to hold the lever andthe jaw 4 against movement,'and a spring 31, secured to the lever, bears-at its free endupon the upperside of "the lip23 and thereby normally holds the dog in engagement with the shank."V

A slip handle 32 is fitted upon the end of the shank 1 to provide a comfortablegrip for the workman and also to serve :as a stop to limit the movement of thejaw 4 and the Patented July 2, 191s.
