JACOB VAN ICE, HIDDILBURG, NETHERLANDS.
OPEN-END WRENCH 01' TH! ADJ'U STABLE-31W ml.
Application filed June 12, 1928, Serial Io. 115,817, and in Germany September 88, 1015.
My present invention relates to open end wrenches of the typevin which one jaw is hinged to the handle, the other jaw being slidably mounted relative to the hinged 'aw and connected with the handle throu a rod of adjustable length. The object o my invention is to generally improve the construction of knownwrenches of this type and to provide an open end wrench which is easy to handle. With these objects in view, I sug est to mount the jaws in an inclined position relative to the axis of the handle so that the hinged jaw is nearer to the free end of the handle than, is the slidable jaw and also its hinge is nearer to said free end than is the connection between the slidable jaw and the adjustable rod, and further, to provide the handle on both side .faces and on either side of the hinge with abutments for the hinged jaw, the said rod being ada ted to perform a swinging movement int e space between said abutments.
In order that my invention may be fully understood, I shall proceed to describe the 5 same with referenceto the annexed drawing,
on which:
Fig. 1 shows a side elevational view of a screw wrench,
gig. 2 a sectional elevation of said wrench an Fig. 3 a cross sectional view along the line III-III in Fig. 1.
Fig. 4 shows a side elevational view of a pipe wrenc The jaw 2 of the screw wrench according to Figs. 1--3 is hinged as at 3 to the handle 1. Said jaw is provided with a rectilinear guideway for the jaw 4:, which is ivoted as at 5 to a rod 6 threaded on its ower end portion so that its operative length can be adjusted by means of a nut 7 located between two filling pieces 8, 9. A
spring blade 10, riveted as at 11 to the handle 1 and exerting a certain amount 0 5 pressure as at 12 against the rod 6, tends to hold the jaw 2 in engagement with abutments 13 on the side faces of the handle. Similar abutments 14 serve to take up the pressure of the hinged jaw 2 when the screw wrench is used in a reversed position (as compared with the position for normal use for tightening up or loosening nuts who are not easily accessible.
The screw wrench 1s shown in a position u in which it is used for tightening up a nut f adjustable rod connected with the slidable on a right hand threaded screw bolt, said nut bem shown in dash and dot lines. B means 0 the nut 7, the wrench is first a usted to fit the nut to be tightened u If, then, the handle 1 is forced to the aft, it tends to swing about the pivots 3 of the jaw 2, whereby a pull is exerted throu h the rod 6 on the aw 4, so that the nut 1s clamped between t e jaws, the clamping force being proportionate to the resistance ofiered by the nut a ainst its rotation.
the andle has moved through a suff(ic1enttangfi1lar iisfancg, it is moved back 1.e. o' erigt,wenita inswmgs' about the pivots 3. The rod 6 n v acts as a push rod against the jaw 4 so as to move the same awa from the jaw 2, whereb the nut to be tig tened up 1s released an the aws turn through a small angular distance 1n an anticlockwise direction. At first, however, said angular distance is insufiicient to permit the jaws to pass the corners of the nut, so that the swinging movement of the handle 1 about the pivots 3 is continued and the jaw 4 moves further away from jaw 2. equal to the maximum diameter of the nut, When the distance between the jaws is equal to the maximum diameter of the nut, the jaws pass the corners of the nut and are restored to their normal positions by the action of spring 10 so as to grip the next pair of parallel nut faces, and so on.
If the nut is to be loosened, the wrench is used in the reversed position.
Fig.4 does not require to be explained in further detail, since the ipe wrench illustrated therein corres on s in construction with that of the a ove described screw wrench.-
What I claim is 1. An open end wrench including a jaw hinged to the handle another jaw slidably mounted relative to the hinged jaw and an jaw and the handle, said jaws being mounted in an inclined position relative to the axis of the handle so that the hinged jaw is nearer to the free end of the handle than is the slidable jaw and also its hinge is nearer to said free end than is the connection between the slidable jaw and the adjustable rod, and further characterized b the fact, that the handle is provided on bot side faces and on either side of the with abutments forthe hinged jaw, the said no rod being adatplted to perform a swinging movement in e space between said a utments. v
2. An open end wrench including a handle, a jaw member pivoted to the handle, abutment means on t e handle to engage with .the 'a'w upon relative movement be tween the aw and the handle, a slidable jaw mounted in the 'aw which is pivoted to the handle, means or setting the slidable jaw with reference to the pivoted jaw, and means for yieldingly placing said last named means under tension.
8. An open end wrench comprising a handle, a jaw pivoted to the handle, abutll ment means on the handle at opposite sides of the pivot and adapted to engage the jaw upon relative movement between the same and the handle, a jaw slidably mounted in the pivoted jaw, a member having one end pivotall connected to the slidable jaw means or on aging the other end of sai member to a just the same longitudinally and also permlt of its swinging movement, and a spring for tensioning t movement of said member.
In testimony whereof I 'afiix my si JACOB VAN ature.
