This class includes patents for the production and transmission of electric power and does not include any specific use to which the power is put. (Note. The mere reference to or the inclusion in a claim of an energy-consuming device, broadly stated--as, for example, a "lamp", "heater", or "tool"--is not sufficient to exclude the patent from this class). It includes the following groups when the invention includes some motor other than a dynamo electric machine in combination with a dynamo electric machine:
Wherein a proximate function of the entire combination is the generation of electricity by a dynamo-electric machine or such generation combined with the transmission, storage, or control of the current generated. There may be an additional function of production, transmission, storage, or control of some power other than electrical.
Wherein a proximate function of the entire combination is that of an electric motor. There may be an additional function of production, transmission, storage, or control of some power other than electrical.
Wherein the direction in which the energy flows (whether from the dynamo electric machine to the motor or from the motor to the dynamo-electric machine) is not essential to the invention. These are mostly structural combinations. Includes the combination of an internal-combustion engine and magneto unless the ignition system is claimed. A magneto in combination with a timing means is regarded as a subcombination of an internal-combustion engine.
Wherein the operation involves an interchange of energy between the motor and the dynamo-electric machine and the dynamo electric machine is not subsidiary to the motor, but may as well be a source of external energy as the motor. A magneto connected with an ignition system of an internal-combustion engine is considered subsidiary to the internal-combustion engine.
Dynamo electric-machine starters for engines, the dynamo electric machine being mechanically connected to the engine to drive the same. Claims including an engine and starter, if the latter is shown as a dynamo electric machine starter, are included. Dynamo electric machines disclosed as starters for engines are included, even through the engine is not claimed, provided the elements claimed require for their operation a reversal of energy flow to and from the engine.
Power production and transmission systems wherein the dynamo electric machine above referred to charges a storage battery.
(1) Note. Pumps operated by motors, which motors are controlled by fluid-pressure or other fluid condition produced by the pump, are excluded. (2) Note. All patents in this class disclosing dynamo electric machines having a "rotary field and armature", special internal-combustion-engine "ignition", prime-mover "starting-motors", or "engine-control" features may be found by searching the subclasses having these terms in their titles.
(3) Note. All patents disclosing batteries may be found by searching subclasses 16, 41 and 50, and the "starting-motor" subclasses.

74, Machine Element or Mechanism, and 192, Clutches and Power-Stop Control, for the combinations of this class where
the starter is merely a cranking means for the engine and the invention resides in the gearing or clutch connecting the starter to the engine, respectively.
123, Internal-Combustion Engines, for the combinations of this class where the starter is merely a cranking means adjunctive to means modifying the operation of an internal-combustion engine, and no other structure of the starter of its relation to the engine is claimed than would be set forth by the mere inclusion of the electric motor as an element of the combination.
