Abstract:
A cross-bar socket wrench comprising, in combination, a body member consisting of an elongated shaft with a rotatable gripping handle at one end thereof and a socket-engaging tip at the opposed end thereof and with a torque bar retaining driving hub secured to said elongated shaft generally midway between said opposed ends and a pair of torque bars coupled to said driving hub, the combination being characterized in that:(a) said gripping handle comprises sleeve means mounted coaxially upon said elongated shaft and being freely rotatable thereabouts for accommodating rotation of said elongated shaft relative to said gripping handle; (b) said driving hub having a central bore for securing said elongated shaft and a pair of radially outwardly disposed bar receiving drive pockets for pivotal articulation of said torque bars formed therewithin; (c) a pair of elongated torque applying bars pivotally coupled to said hub within said pockets, each bar comprising an elongated body with the proximal end pivotally coupled to said hub and being adapted for rotation about pivot pins secured to said hub, said torque bars being adapted for articulation between inwardly retracted and radially extended dispositions; (e) the configuration of said bar receiving pockets accommodating pivotal rotation of said elongated torque-applying bars from a retracted disposition substantially parallel with said elongated shaft to an extended working disposition at an oblique angle relative to the axis of said shaft of between about 94Â° and 98Â°.
