This class includes the elementary structure of a running-gear
for a land vehicle, that is, commonly known as a "wheel" or
an "axle", per se. The combination of a "significant" wheel
or axle with "nominal" other structure, i.e.,
wherein the wheel or axle comprises the dominant feature or essential
part, is also found in this class.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(1) This class is subordinate to Class 280, Land Vehicles,
and distinguishes therefrom by the above definition.
(2) This class is subordinate to Class 180, Motor Vehicles.
The broader or more comprehensive combinations of cooperating structure
of a wheel and axle with other elements of a motor-vehicle are classified
in Class 180. Such cooperating structure on the wheel and axle
is found in this class (301) only where its modification is for
wheel and axle structure purposes alone.
(3) The combination of a detailed wheel with a detailed brake
is found in Class 301. A brake with only enough wheel structure
to support the brake is found in Class 188, Brakes.
(4) A wheel or the combination of a wheel with a resilient
tire or with a resilient wheel component is normally found in Class
301. A resilient tire, a resilient wheel, or a resilient wheel
component is found in Class 152. For example, a resilient tire
with a rim including details of the rim allowing the tire to be
seated thereon is found in Class 152, but it is found in Class
301 if further including mounting structure for supporting that
structure on a bearing hub. A traction-increasing device supported
by a wheel, even though combined with a resilient tire, is found
in Class 301, but another traction-increasing device operative to
engage the tread of the tire and permit resilient operation thereof
is found in Class 152.
(5) A device which functions as a transportation means for
a vehicle, but which is not a true wheel, is found in Class 180,
Motor Vehicles, subclasses 7.1+; and Class 305, Wheel Substitutes
for Land Vehicles.
Machine Element or Mechanism, for a casing for an axle; or for an axle (especially
a motor vehicle axle) which involves improvement in the gear casing
or in the gearing. An axle housing, per se (which may be recited
as an "axle") is found in Class 301.
Wheel Substitutes for Land Vehicles,
subclass 7 for a rigid circular track provided with a wheel
or roller within the track the axis of which is eccentrically positioned
with relation to the axis of the track, said wheel or roller being
adapted to roll on a lower portion of the track, and subclasses
124+ for wheels especially modified to be used in flexible
track apparatus for land vehicles. For a patent claiming a wheel,
per se, to be placed in Class 305 the wheel as disclosed must include
structure which coacts with a track part, such as a flanged rim,
or a grooved rim which structure is adapted to interengage with
a portion of a flexible track. A wheel which does not incorporate
such structure, even though disclosed as being a flexible track-supporting
wheel, is classified in this class (301).
This subclass is indented under the class definition. Combination involving combined modification of both wheel
and axle or modification of one which affects the operation of the
other.
