DEFINITION

Classification: 192/3.27

(under subclass 3.25) Device including two clutches wherein either a first or a second of the clutches (but not both simultaneously) is in force-transmitting relationship.

(1) Note. The patents in this subclass usually disclose only two clutches in combination with a vortex-flow drive. A patent claiming a vortex-flow drive and only two clutches that are alternatively operable is proper as an original patent for this subclass even though it may disclose more than two clutches.
