WITH FLUID OR MECHANICAL MEANS TO ACCUMULATE ENERGY (I)DERIVED FROM MOTION OF VEHICLE OR (II) OBTAINED FROMOPERATION OF VEHICLE MOTOR, AND GIVE UP THE ENERGY (1) WHENNEEDED FOR VEHICLE ACCELERATION OR (2) TO POWER AN AUXILIARYSYSTEM OF THE VEHICLE:
(under the class definition) Vehicle provided with means of a fluid or a mechanical nature (e.g., pressure reservoir, flywheel) to receive and retain energy which (I) results from the momentum of the vehicle in ordinary travel, or any other movement of all or part of the vehicle ancillary thereto, or (II) is produced by the operation of the motor of the vehicle (which operation may or may not serve simultaneously a vehicle propelling purpose) which means will, upon demand, feed back the stored energy (1) to aid in starting up or increasing the speed of the vehicle or (2) to drive or otherwise operate a system of the vehicle which serves other than a propelling purpose.
(1) Note. This subclass was established during the project which reclassified former subclasses 1, 3+, 25+, 42+, 64, 66+, 82+, and 115 and is intended to provide a locus for collecting art which relates to certain aspects of conserving the energy required for the operation of a motor vehicle. The art initially placed here was assembled primarily from the informal records of an examiner in the class and secondarily from screening the subclasses listed above; while the collection is believed to be relatively complete, also, insofar as the nonreclassified portion of the class is concerned, it may presently contain only a minor portion of such relevant art as exists in other classes. Inasmuch as the development of a subclass of this nature was beyond the original scope of the project, it was necessary to keep the subclass concept relatively narrow, e.g., to have broadened it to include energy conservation devices of the kind
commonly associated with electrically propelled vehicles would have involved reviewing such relatively large fields of art as dynamic braking, motors which may function alternatively as generators, etc.

408, for a motor and a source of fluid for driving the motor, and wherein the fluid is in the form of a gas which is supplied to or removed from the motor by, e.g., a pump, and wherein is further provided a storage vessel for serving as the gas supplying or removing device and additionally wherein the motor is a unit which is usable either as a motor (when driven by gas from the charged storage vessel) or as a pump (when used to charge the vessel); and subclasses 413+ for a motor and a source of fluid for driving the motor, and wherein is provided structure that stores energy and also a manual or condition responsive means for controlling either the input to the storage means or the output therefrom.
280, Land Vehicles,
212+, for a land vehicle of the wheeled type provided with positive means adapting it to be propelled by an occupant, and wherein the means is one operable by the occupant, and further wherein is additionally provided a means for storing energy, which energy is expended in driving the vehicle.
