.~ Shaft transmission train having flexible means or coupling
DEFINITION
Classification: 415/124.2
Shaft transmission train having flexible means or coupling:
(under subclass 122.1) Device comprising means to transmit motion between a runner* and a driven or driving shaft* which means causes or permits relative motion or speed between the runner and the shaft. The means includes (a) a motion transmitting means which, by design, bends or otherwise exhibits nonrigid properties or (b) a driving connection between two motion transmitting elements of the means which allows nonrigid movement of the two elements relative to one another (i.e., a fixed movement of one element does not continuously correspond to a fixed movement of the other element).
(1) Note. A device wherein the means to transmit motion comprises a motion transmitting shaft which is coupled to another motion transmitting shaft by a flexible joint (e.g., U-Joint) is included in this subclass.
(2) Note. A friction, fluid, or magnetic coupling which connects two motion transmitting elements nonrigidly is included in this subclass provided the coupling does not serve to connect and disconnect the two motion transmitting means. The latter coupling type is a clutch (see subclass 123).
(3) Note. A driving connection between two motion transmitting elements which permits nondrive related movement between the elements is included in this subclass (e.g., two intermeshing gears rotating about parallel axes which are permitted to move axially relative to each other without affecting the drive relationship).
(4) Note. A motion transmitting means comprising two conventional gears in direct driving relationship is not included in this subclass.

123, for a device having means to connect and disconnect the runner supporting shaft with the driven or driving shaft.
