Unidirectional drive hand operated wrench

A unidirectional drive hand operated wrench comprising:

• first and second pivotally connected angularly displaceable elongated handles;
• a rotatable drive stud;
• drive means connecting said handles to said drive stud such that manual angular displacement of said handles with respect to each other in either direction causes unidirectional rotation of said drive stud;
• reversing means associated with said drive means for reversing the unidirectional rotation of said drive stud;
• said first handle comprising a pair of spaced arms and said second handle including a gripping portion positionable between the spaced arms of said first handle when said handles are co-linear, said wrench further including a shaft rotatably supported between said arms, said second handle including a shaft-like driver member connected to said gripping portion and rotatably supported by said shaft, a first driver bevel gear rotatably mounted on said shaft between said drive member and one of said arms, a second driver bevel gear non-rotatably mounted on said shaft between said drive member and the other of said arms, said drive stud being connected to one of said gears for rotation therewith, a bevel pinion gear rotatably mounted on said driver member on either side of said shaft, said pinion gears meshing with said bevel gears, said reversing means including pawl means for permitting rotation of each of said bevel gears in only one direction.
