DEFINITION

Classification: 239/265.11

(under the class definition) Apparatus comprising the distributor for the fluid ejected from a reaction motor to produce a thrust.

(1) Note. The "reaction motor" of this definition is the motor forming the subject matter of Class 60, Power Plants, subclasses 35.5+, the subject matter falling under this definition being the nozzle or distributor subcombination of such motor coming within the class definition of Class 239.

(2) Note. A claim reciting a combustion chamber or other means imparting energy to the fluid is not excluded from this and the indented subclasses in the absence of specific details of the energy imparting means or a specific relationship between the means and the terminal member.

(3) Note. See Class 60, Power Plants, subclasses 200.1+ (5) Note for examples of vehicle structure considered to be significantly claimed, which note must be considered in relation to the vehicle classes indicated under Search Class (below).

SEE OR SEARCH THIS CLASS, SUBCLASS:

127.1+, for a reaction motor distributor a portion of which has a spaced wall or internal cavity, and a source of cooling fluid connected to the cavity or space, to cool the distributor by transfer of heat to the fluid.

251+, for a reaction type nozzle forming the terminal member of a fluid conduit which is connected for continuous motion relative to a fixed support. SEE OR SEARCH CLASS

60, Power Plants,

35.5+, for reaction motors. Typically, such motors comprise the combination of a reaction type nozzle with means feeding fuel thereto (e.g., after-burner), or combustion chamber details (e.g., materials), or a claimed relationship between a combustion chamber or a turbine or compressor upstream of the nozzle (e.g., pressure or temperature difference across the combustion chamber, turbine or compressor for affecting flow through the fluid system or for controlling a system or nozzle part).

102, Ammunition and Explosives,

347+, for pyrotechnic rockets, subclass 359 for pin wheels, and subclasses 374+ for rocket propulsion of projectiles.

105, Railway Rolling Stock,

26.1+, for a jet propelled rail locomotive.

114, Ships,

151, for reaction motors arranged to steer a ship.

180, Motor Vehicles,

7, for a motor vehicle having means for driving it in some other manner than by drivingly rotating a surface-engaging wheel, which means may be in the nature of jet propulsion. 244, Aeronautics,

12, 15, 23, 29, 52, and 73+ for aircraft sustained by the thrust of a reaction motor or propelled or steered by a reaction motor.

415, Rotary Kinetic Fluid Motors or Pumps,

80+, for a reaction type nozzle on a fluid jet motivated turbine runner.

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

20+, for a reaction type nozzle on a fluid jet driven impeller.

431, Combustion,

158, for a chamber specialized to combustion feeding a jet nozzle of general utility.

440, Marine Propulsion,

38+, for reaction motors which propel or propel and steer a ship.

446, Amusement Devices: Toys, 163, for jet propelled boats and subclasses 211+ for other jet propelled toys.
