With the present device, one person 18 has the long arm 16 thereof slotted as at,

17 through which slot the wrench 14 is insertable, and the upper portion 18 of the arm 16 is preferably of bendable spring material and the block 19 at the inner termination of the slot 17 is preferably of a thickness slightly less than that of the wrench 14.

This construction is such as to permit the free sliding movement of the wrench 14 I within the slot 17 and at the same time provide means for rigidly securing the wrench 14 therein in any desired position, which means consists of a screw bolt 20 carried by the lower portion 21 of the member 13 and passing upwardly through the portion 18 and provided with a binding nut 22. With this construction, as will be readily seen,the nut 22 is screwed down to draw the end of portion 18 toward the portion 21, which will firmly bind or clamp the wrench 14 therebetween. The member 13 is preferably formed of but three pieces, the lower piece 21 being of heavy material and of substantially L shape, the block 19 secured to the portion 21 at the angle thereof, and the strip 18 which is secured to the block 19 and held spaced from the long arm of the portion 21 to form the slot 17.

The short arm 23 of the holding member has pivotally secured thereto, and extending downwardly in opposite direction from the screw 20, a screw 24 upon which the wrench 15 is adjustably secured by projecting the screw between a threaded opening'25. This construction permits the wrench 14 to be adjustably spaced from the member 13, as will be readily apparent, and consequently adjustably spaced sidewise with respect to the wrench 15. All of the wrenches em ployed in connection with my improved tool are provided with a centrally threaded opening 25 to permit the securement of the same upon the screw 24 when not in use as best shown in Fig. 3, so that the wrenches will not become lost from the holder.

In use, the wrench 15 is secured upon the screw 24 in the proper relation with respect to the holding member and wrench 14 is then inserted through the slot 17 with the nut 22 loose upon the screw 20, when the wrench 14 is manipulated to obtain the proper adjustment of the adjusting screw 8. When the proper adjustment is obtained the nut 22 is screwed down to firmly bind the wrench 14 in'the position it occupies when the adjustment is obtained. With the wrenches 14 and 15 thus firmly secured in their position of adjustment, engaging the flat faces of the member 7 and the head 9 of the screw 8, the third wrench 12 is inserted therebetween to tighten the lock nut 10 and lock the screw 8 in its position of adjustment.

As will be readily apparent to those skilled in the art to which an invention of this character appertains, by reason of the wrenches 14 and 15 being capable of adjustment in sidewise spaced relation and of adjustment to various angles with respect to each other the tool may be readily manipulated to operate in the most efficient manner.

hat I claim as my invention is:

1. A device of the class described comprising a slotted member through which a wrench is insertable and slidable, and turnable with relation to its work engaging end, and-means carried by said member for pivotal engagement with a second wrench to permit both wrenches to simultaneously engage nuts mounted on the same threaded member.

2. A device of the class described comprising a slotted member through which a wrench is insertable and turnable with relation to its work engaging end, and means carried by said member for pivotal engagement with a second wrenchfor holding the same in sidewise spaced relation and at an angle with respect to the work engaging end of the wrench 'insertedthrough the slot of said member.

3. A device of the class described comprising a pivoted holding member having a slotted arm through which a wrench is insertable and turnable with relation to its work engaging end, a threaded shaft upon which a second wrench is securable to be held in sidewise spaced relation with respect to the first mentioned wrench, and means for locking the wrenches in various adjusted positions with respect to each other.

4. A device of the class described comprising a. pivoted holding member having a slotted arm through which a wrench is insertable at an angle, athreaded shaft upon which the second wrench is securable to be held in sidewise spaced relation with respect to thefirst mentioned wrench, and means for securing said wrenches in various angular positions of adjustment with respect to each other with their inner work engaging ends in alinement.

5. A device of the class described comprising a pivoted holding member having a slotted arm through which a wrench is insertable at an angle, a threaded shaft upon which the second wrench is securable to be held in sidewise spaced relation with re spect to the first mentioned wrench, means for securing said wrenches in various angular positions of adjustment with respect to each other with their inner ends in alinement for engagement with the parts to be held, and means for securing said Wrenches ment, and means carried by the short arm in sidewise spaced relation. of the L for adjustably securing a Wrench 10 6.
