THREADING ATTACHMENT ABSTRACT OF THE DISCLOSURE A reversible driver for a threading tool, such as a tap or die, is disclosed. The driver has rotary input and output members with a forward clutch connected therebetween and a reverse clutch connected through reverse gearing between the input and the output members. Each clutch has drive and driven clutch elements and a first spring urges both forward and reverse clutches toward engagement. A second spring is stronger than the first spring and urges the forward clutch toward engagement so that a tap rotated by the output member will tap a hole in a workpiece until the for- ward clutch is released. Each clutch utilizes a plurality of substantially hemispherical projections engaging longitudinal abutments as a form of dog clutch. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
