an elongated slot62 formed therein, as perceived in Figure 40f the drawings. Thus, rotation of the arm 50, through the wheel 56, moves the block 60 and the pin 30. Movement of the pin' 30 efiects a corresponding movement of the jaw 24.
In operation, the first pivot .point J6 serves as the axis of the levers. When thelevers are moved apart, the pivot l6 drops and conversely moves upwardly when the levers are pressed together. When an intermediate position is assumed by the pivot, the pressure on the levers is balanced and no grip pressure is required to maintain the jaw pressure. This allows the levers to be pressed together with the sections I8 and 20 abutting and yet-keeps the correct pressure on the jaws.
A modified formof jaw isprovided in Figure 3 of the drawings, wherein the wrench I isjadaptable for use as a wire cutter. gripping faces of the jaws 24 and 2B are triangularly projected to receive and accommodate cutting blades 64 and 66 detachablysecured on the faces. or the like, are held on the gripping portions of the jaws, through the medium of spring steel clamping arms 68, which project from the blades. The arms 68 are formed with inwardly directed detents 10, which are adapted to be received within recesses 12 formed in the sides of the jaws 24 and 26, adjacent the face portion thereof. I
Thus, there is provided a compact and eflicient and adjustable locking wrench, which will serve many utilitarian purposes, due tothe angular adjustment, which may be effected on the jaws, as a unit and relative to each other.
However, manyother purposes and objects of this invention will become apparent to those skilled in the art, upon a perusal ofv the foregoing description, in view of theaccompanying drawings, and it is understood that certain changes may be effected therein, within the spirit of'the invention and scope of the appended claims.
Having described the invention,'what isjclaimed as new'is:
1. An adjustable work handling" tool comprising a first and a second lever, a'first pivot connecting said'levers to each other adjacent'lone end thereof, a first'rigid jaw member, a second pivot connecting said first jaw memberto said first lever adjacent the pivoted end thereof, a
from the line defined by said first and second pivots when said levers are in their closed position, means carried by said second lever for adjustably moving said third pivot towards and "away from-said first pivot.
2. An adjustable work handling tool comprising a first and a second lever, a first pivot connecting said levers to each other adjacent one end thereof, a first rigid jaw member, a second pivot connecting said first jaw member to said first lever adjacent the pivoted end thereof, a second rigid jaw member, a third pivot connecting said second jaw member to said second lever adjacent the pivoted end thereof, a fourth pivot connecting said first and second jaw members to each other intermediate the ends thereof, means carried by said levers limiting closing movement The cutting blades, for cutting bolts thereof, said third pivot being laterally offset justably moving said third pivot in a path parallel The cooperating I to a line extendingradially of said first pivot.
3.'An.adjustable work handling tool comprising a first'and a, second lever, a first pivot connecting said levers to each other adjacent one end thereof, a first rigid jaw member, a second pivot'connecting said first jaw member to said first lever adjacent the pivoted end thereof, a second rigid jaw member, a third pivot connecting said second jaw member to said second lever adjacent the pivoted end thereof, a fourth pivot connecting said first and second jaw members to each other, intermediate the ends thereof, said second jaw member having an elongated slot therein, said third pivot being longitudinally adjustably received in said slot whereby the angular portion of said jaw members as a unit ma be varied relative to said levers.
4. An adjustable work handling tool comprising a first and a second lever, a first pivot connecting said levers to each other adjacent one end thereof, a first rigid jaw member, a second pivot connecting said first jaw member to said first lever adjacent the pivoted end thereof, a second rigid jaw member, a third pivot connecting saidsecond jaw member to said second lever adjacent the pivoted end thereof, a fourth pivot connecting said first and second jaw members to each other intermediate the ends thereof, a lead screw carried by said second lever and extending transversely of said first pivot, a follower carried by said lead screw, said third pivot being carried by said follower.
5. An adjustable work handling tool comprising a first and a second lever, a first pivot connecting said levers to each other adjacent one end thereof, a first rigid jaw member, a second pivot connecting said first jaw member to said first lever adjacent the pivoted end thereof, a second rigid jaw member, a third pivot connecting said second jaw member to said second lever adjacent the pivoted end thereof, a fourth pivot connecting said first and second jaw members to each other intermediate the ends thereof, means carried by said levers'limiting closing movement thereof, said third pivot being laterally offset towards the handle portion of'said second lever from the line defined by said first and second pivots when said levers are in their closed position, a lead'scr'ew carried by said second'lever and extending transversely of said first pivot, a
follower carried by said lead screw, said third pivot being carriedby said followerj JOHN W. BURROWS.
