DEFINITION

Classification: 89/1.8

(under the class definition) Subject matter relating to the launching of a rocket.

(1) Note. For the purpose of this definition a rocket is defined as a vehicle, which may or may not be specifically described, having therein a reaction motor and a propellant, whereby, independent of atmospheric oxygen, propulsion gas may be produced by a chemical reaction. However, in the case where the rocket, before being launched is located entirely or partially under water, and during launching, or soon thereafter, a part or all of the rocket contacts the water, the rocket propulsion gas, or any other pressurized fluid employed to launch the rocket, may be produced by a chemical reaction or by a nonchemical-reaction means.

(2) Note. The word launch means to cause to be moved for disengagement from a supporting environment either (a) by the thrust created by the reaction motor of the rocket being launched alone or (b) by an additional propelling force and the thrust of the reaction motor of the rocket.

(3) Note. Subject matter under this definition includes transport, storage, connector, latch, ejecting, exhaust gas deflecting structures or the like for a rocket which are in combination with either the rocket or launcher for a launching purpose and which are not classified elsewhere.

(4) Note. To be classified under this definition in the case of a rocket not launched under water, as defined in (1) Note, at least a portion of the propulsion gases emitted by the rocket whether generated outside the rocket or in the rocket are required to be produced by a chemical reaction.

(5) Note. For original classification of a patent under this definition, rather than in other appropriate subclasses of Class 89, the sole disclosed use or a claim thereof must be for launching a rocket. SEE OR SEARCH THIS CLASS, SUBCLASS:

33.01+, for devices which hold or feed a plurality of cartridges to a gun.

37.01+, for gun mounts in general.

45+, for means for placing a load into firing position in a gun.

125+, for automatic gun structures which could be utilized in the launching of rockets.

SEE OR SEARCH CLASS

102, Ammunition and Explosives,

347+, for rocket support sticks and other supports for pyrotechnic rockets wherein the supports are integral with the rocket and are launched therewith.

104, Railways,

48+, for rail transfer structure and subclasses 89+ for suspended rail structures, per se.

114, Ships,

18+, and 316+ for vessels having means for launching a torpedo. 124, Mechanical Guns and Projectors, various subclasses, for apparatus employing nonexplosive means to impel or launch a projectile wherein the projectile is disclosed as having a chemical reaction motor which is claimed in name only. Patents are also classified in Class 124 which claim significant projectile structure having a propelling agent which is either produced by a nonchemical reaction or is a stored pressurized fluid. However, the combination of a projectile (regardless of its propulsion means) with a launching platform submerged in a liquid is classified in Class 89,

1.8+,.

198, Conveyors: Power-Driven, various subclasses, for power driven conveyor devices, per se.

200, Electricity: Circuit Makers and Breakers, various subclasses for electrical switch devices which interrupt the flow of electricity but which normally remain connected in the electrical circuit.

206, Special Receptacle or Package,

317, for a container for a weapon.

244, Aeronautics,

2+, for means to launch and lift an aircraft, and subclass 63 for devices and arrangements adapted to assist in the take off of aircraft from land or water. Launching devices disclosed as rocket launchers wherein the rocket is claimed in name only are classified in Class 244. Also, launchable devices comprising propeller blades and flight control surfaces disclosed as a stage of a rocket-launching means are classified in Class 244.

361, Electricity: Electrical Systems and Devices,

248+, for electrical arc or spark means for igniting a fuel by which a rocket may be propelled.

414, Material or Article Handling, various subclasses for rocket handling structures which do not provide means for the launching of the rocket. 439, Electrical Connectors, various subclasses for details of electrical connections which permit making and breaking of an electrical circuit by physical separation of conductors.

446, Amusement Devices: Toys,

212, for reaction propulsion toy launchers having nonchemical reaction propulsion devices.
