Lever 3, designed as a fork, turns about fixed axis A. Disks 2 and 4 rotate about fixed axes C and B. This mechanism is intended for transferring workpieces a from one inspecting operation to the next. Disk 4, turning about horizontal axis B, picks up workpiece a with its grooves b and carries it to the measuring device (not shown in the drawing) located at the upper point of disk 4 where the inspecting operation is performed. Then disk 4 turns 90° and workpiece a is picked up by the fork of rocking lever 3 and transferred to disk 2 where another measuring device performs an inspecting operation.
