Abstract

The fork head spanner uses a return sprung (4) slidable wedge (3), mounted on a curved or inclined jaw face to provide a ratchet effect, thus allowing the head to slip over a nut (2), or bolt head during recovery rotation. The wedge and the opposite jaw may be indented (1), to permit the gripping of nut or bolt head corners rather than the flats. The spanner rotation tends to drive the wedge into the fork and has the effect of tightening the grip. - It is pref. to make the spanner solid. When the jaws slide over the nut they have a tendency to wedge between the nut and the bend of the spanner.(4/4)
