The object of this invention is to provide a wrench where the aws operate in shdmg relation.
V A further ob ect this invention is to provide a wrench having three operating membors all in sliding relation.
A further object of this invention is to provide a wrench having a stationary member a same.
' Referring now to the drawing, the numeral 1 indicates a stationary member, having at its extremeupper end a 13W, 2. On oneside of the stationary member a number of teeth 3 are set. The number of teeth depends on thelength of thetool. I
(lo-operating with the aw- 2, on'the stationary member 1, there isafhxed a movable lower jaw 4 on a curved member 5. The apex 6 ofthecu'rve is adapted to rest on the-stationary member and so arranged as to rotate on said stationary member with the apex 6 as a fulcrum. A spring 7 is permanently affixed; to the curved member?) at 8 and is'so ar-' 35 a ainst the stationary member-1, at
ranged that the loose end 9 thereof sets g about the location of the lower jaw 4. I v On the other side of the stationary member 1, there is arranged a curved handle 10, having the curve 11 resting against the station ary member 1. The curved handle has a tooth 12 set so as to coaot with the teeth 3 on "the'stationary member 1.
The curved handle 10 and 5 are held together by means of links 13 and 14 spanning the stationary member 1.
The links 13'join thefend of the curved handle 10 with the lower jaw 4.. The'links Fig. 1, is a View of the wrench before using Fig. 2, is a view of the wrench in the act of curved member 1 14 join the curved handle 10 alongside the tooth l2 and the'lower end of the curved member 5. It will be noted that the links 13 are perpendicular to the stationary member 1 while the links 14 are oblique t0 the stationarymember 1. v
Rivets 15, 16,17 and 18 are used to hold the l nks and the members together.
In operation, when; a nut of a certain sizer is to be turned the wrench is adjusted by holding the stationary member 1, in one hand and'moving the curved handle 10 outward,
so as to disengage the tooth'12 from the teeth 1 8 and when disengaged the lower jaw 4 can be moved up or down by means of the curved handle 10. When the approximate size of opening is obtained the curved handle is pressed against the stationary memberl, thus obtaining a positiveengagement of the tooth 12 and teeth 3 and also swinging the lower aw 4'on 1ts curved apex6 so that the faces of the jaws become parallel, thus affording a better grlp of the nut.
While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall 7 within the spirit andscope of the invention as defined in the appended claim.
What I claim is z, l e Inadevice of the class described, a stationary member having a'fixed jaw,- a curved member having a jaw at its upper end, said j curved member restingits curve agamstthe stationary member, a curved handle resting wlth 1ts curve against theother side of said stationary member, means for oonnectlng the curved handle and curvedmember, teeth'on' the stationary member, a tooth on the curved handle and adapted to pivotally engage'the teeth on the stationarymember, and so ar-.
ranged that when the handle is in non-operative position'the jaws are angular rela tion and when the handleIi's in operative position the jaws are in parallel relation.
