ABSTRACT:
A rotatable cylinder having a plurality of drivers mounted therein for axial movement with each driver having a projection thereon extending through openings in the cylinder to engage rotatably mounted rings coaxially positioned around the cylinder and a disk having a depression therein for receiving one of said drivers at a time as the disk and cylinder are rotated. When the disk and cylinder are rotated in one direction a driver positioned in the depression engages an associated ring to rotate the ring. As the disk and cylinder are rotated in an opposite direction the first driver is cammed from the depression and a second driver drops into place. The rings engage different conductors as they rotate to provide the encoding.
