DEFINITION

Classification: 74/665

(under subclass 640) Gearing in which a plurality of power paths constitute either the input or the output of the gearing.

(1) Note. For the most part, the gearing serves either to divide a single input into a plurality of outputs, or combine a plurality of inputs into a single output.

SEE OR SEARCH THIS CLASS, SUBCLASS:

11+, for power take offs.

625+, for alternate manual and power operators in general.

661, for plural prime movers selectively coupled to common

output. 810.1+, for nonplanetary gearing wherein reverse torque changes power transmission to an alternate path.

180, Motor Vehicles,

6.2+, as explained in the reference thereto appearing in subclass 664 above.

188, Brakes, appropriate subclasses, for brakes mounted on motor vehicles, not structurally related to a gearing (which is not specifically claimed) for controlling the gearing; i.e., brakes on the rear axle which are independently operable and hence incidentally control the relative output of the differential.

192, Clutches and Power-Stop Control, the un-numbered title "Interrelated power delivery controls" and see the notes thereto for interrelated control of one or more of prime movers, clutches, gearing, brakes and loads by name only.

408, Cutting by Use of Rotating Axially Moving Tool,

31+, for the combination of plural tools of that class type combined with drive means utilizing plural power path gearing.

475, Planetary Gear Transmission Systems or Components, for plural power paths to or from planetary gearing.
