Abstract:
A metered torque wrench which comprises:an elongated housing; a stack of resislient metal strips enclosed in said housing: said stack having a long dimension extending in a direction of a long dimension of said housing; means for securing one end of said stack in one end of said housing; a coupler positioned in another end of said housing and adapted to rotate about an axis parallel to a long dimension of said housing; said coupler having means for securing one end of said coupler to another end of said stack; said coupler having another end extending from said another end of said housing accessible for mounting a drive on said another end of said coupler; a dial plate having a circular dial scale whose outside diameter is larger than a diameter of said housing; means for mounting said dial plate on said coupler having said dial scale concentric with an axis of said housing and adjacent to a rim bounding said another end of said housing; a marker on a surface of said housing arranged to indicate a rotational position of said housing relative to an orign of said dial scale providing that, when said another end of said coupler is engaged with a drive and said housing is rotated, said marker is displaced from said origin by a displacement value corresponding to a value of torque applied to said housing relative to said coupler.
