Abstract
A socket drive spanner having an outer tube and a conventional half inch square driver protruding therefrom. A spindle and an inner tube are located within the outer tube and the spindle is rotated by axially moving a rod which is perpendicular to the outer tube. The rod has a cable pulley system which wraps around the spindle, thereby rotating it, the inner tube the spindle and the half inch square driver are engaged together and rotate in unison. When the half inch square driver is disengaged from the inner tube, and locked into place the half-inch square driver is then stationary with respect to the outer tube and hence the spanner can then be used in a conventional manner.
Claims10
A socket drive spanner having a first rigid tube, a second rigid tube co-axially received within one end of said first tube and having an inner end and an outer end, a socket driver means partially received within the outer end of said second tube for rotation therewith, a spindle co-axially received within said first tube and having one inner end partially received within the inner end of said second tube, to permit sliding engagement but prevent rotation therebetween, and said one end of said first tube being slidably engageable with said socket driver means to prevent rotation therebetween, wherein said spindle, said second tube and said socket driver means are rotatable in unison relative to said first tube only when said socket driver means is slidably dis-engaged from one end of said first tube.
