DEFINITION

Classification: 60/698

(under the class definition) Apparatus including (1) a device having a mechanical output operable selectively or simultaneously from diverse inputs; (2) a device or assembly including plural motors at least one of which may be separately supplied with motive fluid or may be operated while another is not producing power; or (3) methods of operating such devices.

(1) Note. This group of subclasses takes plural internal combustion engines of the type classifiable, per se, in Class 123.

SEE OR SEARCH THIS CLASS, SUBCLASS:

39.15+, for multiple fluid operated motors at least one of which is driven by externally generated combustion products.

39.19, for a single motor driven by diverse motive fluids that do not mix in the motor, one of the fluids being combustion products.

224+, for interrelated reaction motors. 244+, for a reaction motor driven by motive fluid from alternate diverse generators.

420+, for a condition responsive control in a pressure fluid source plural motor system.

471, for interconnected control elements operating plural distinct motors in a pressure fluid source motor system.

539, for a programmed, self cycled or self pulsed pulsator system having a cam type drive of plural masters actuating plural motors.

581, for plural structurally related master pistons, cylinders or pulsator circuits.

597+, for a fluid motor driven by the waste heat or exhaust energy from an internal combustion engine.

625+, for an internal combustion engine with a fluid motor, for rotating it for starting or convertible to a fluid motor for initiating rotation.

642+, a system including a motive fluid supplier energized by externally applied heat. See, particularly subclasses 655, 663, 676, 677-680, and 684.

661, for gearing for connecting plural prime movers either individually or unitarily to the same load.

91, Motors: Expansible Chamber Type, 170+, for plural intercontrolled expansible chamber motors; and subclass 441, for a system of expansible chamber motions having plural working members. See (4) Note of the class definition of Class 91, for a statement of the line.

172, Earth Working,

48+, for an earthworking machine having plural driven tools.

192, Clutches and Power-Stop Control,

.098, for the interrelated control of motors and clutches in a system having plural motors.

4, for a prime mover dynamo plant having plural prime movers; and subclass 48, for the combination of an internal combustion engine and its electrical starting motor.

303, Fluid-Pressure and Analogous Brake Systems,

6.01+, for the distribution of pressure fluid to multiple motors, one of which is a brake motor.

318, Electricity: Motive Power Systems,

34+, for plural diverse or diversely controlled electric motors; and appropriate subclass for a residual system of plural electric motors. 415, Rotary Kinetic Fluid Motors or Pumps,

60+, for plural runners supported for relative movement or separate shafts in a rotary kinetic fluid motor system; subclass 144, for plural runner stages on a common shaft with a working fluid branch or bypass; and subclasses 198.1+, for plural blade sets rigidly mounted on a common shaft.

416, Fluid Reaction Surfaces, (i.e., Impellers),

120+, for a system of plural impellers that may drive or be driven by an unconfined fluid.

418, Rotary Expansible Chamber Devices, appropriate subclass for a plurality of rotary expansible chamber motors and see (4) Note of the class definition of Class 91, for a statement of the line between those classes, the same line being maintained between Classes 60 and 418.

475, Planetary Gear Transmission Systems or Components,

1+, for planetary gearing connecting plural prime movers to a load device.
