Ratchet wrench assembly

摘要

There is disclosed a novel ratchet wrench assembly comprised of a barrel assembly visa-versa. a clutching mechanism positioned for rotational movement about a drive shaft of the ratchet wrench assembly including a drive stud and gear assembly. The clutching mechanism of the barrel assembly is interconnected to the drive shaft whereby rotation of the barrel assembly about the axis of the drive shaft in either direction causes the drive shaft to rotate in response thereto and thereby rotate the drive stud through the drive stud and gear assembly in a responsive rotational direction. In a preferred embodiment of the present invention, the clutching mechanism is designed such that the rotational movement of the barrel assembly and the drive stud are coincident, i.e. counter-clockwise rotational movement of the barrel assembly results in a counter-clockwise rotational movement of the drive stud, and thus loosening of a bolt or nut mounted on a right hand threaded stud, and vice-versa.
