This class includes structure and attachments peculiar to mooring
buoys, marker buoys, container buoys and other buoys; structure
and attachment peculiar to rafts, and from analogy, to rafting and
guiding of floating logs and similar material; water rescue apparatus;
and other aquatic devices.
Water rescue apparatus include devices maneuvered on or over
the water surface by one person in order to rescue another person,
passenger enclosing devices which are not buoys, rafts or boats
and garment or other type of buoyant members, commonly known as
personal flotation devices which support a user in the water.
Aquatic devices include swimming aids to cause faster or farther
propulsion through the water by the user"s own swimming
strokes, buoyant or nonbuoyant devices which support a user and
which are caused by external means to roll, skim, glide over or
through the water, buoyant underwater viewing devices, and other
miscellaneous buoyant support devices.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
See Class 440, Marine Propulsion, for buoys or other aquatic
devices comprising a motor propulsion means, or animal or human
powered propulsion means other than swimming aids as defined in
Class 441, subclass 55.
Lifeboats including those which enclose the passenger are
classifiable in Class 114, Ships.
A buoyant device made to simulate an animal, fish, fowl, etc.,
or any part thereof, where such simulation is claimed, is proper
for Class 472. However, where such simulation is disclosed but not
claimed, classification of the buoyant device is proper for Class
441. See the (2) Note under subclass 129 of Class 441 for a statement
of this line.
Class 441, subclass 65 takes all the skimming devices (skis,
sleds, toboggans, etc.) which by claim or by disclosure may be used
on water, even though also useable on snow or ice. Class 280, Land
Vehicles, takes those skimming devices which are useable only on
snow or ice.

some other water related function.

water to calm wave activity is contained in the storage space and
a means for distributing the oil is provided.
This subclass is indented under subclass 35. Device including a structural member used in forming the raft which
is capable of being expanded by the introduction into the member
of a fluent medium, e.g., gas.
This subclass is indented under subclass 35. Having centrally located suspended basket: Device wherein the platform or floor of the raft is in the form
of an open cage hanging in the center of the raft below the level
of a surrounding buoyancy means.
This subclass is indented under subclass 35. Device wherein the raft has an elongated buoyancy providing member
having a cross-section with a periphery of a shape similar to a
circle, or multiple sided geometric figure.
This subclass is indented under subclass 45. Device wherein the buoyancy providing means is a cylinder of flat
or slightly bulging sides having flat parallel ends and a ratio
between the height and the diameter somewhat greater than one.
This subclass is indented under subclass 50. Device wherein the joining means is a bar, rod, or similar rigid
member which is oriented transversely to and affixed to a log for
the purpose of joining them together.
This subclass is indented under the class definition. Device secured to or held by a swimmer which increases the effective
surface used to propel the swimmer through the water, thereby providing
for faster or farther propulsion through the liquid by the user"s
This subclass is indented under the class definition. Device constructed so as to permit walking, gliding, or planing
on the surface of a body of water while sustaining a user substantially
out of contact with the water.
Note. Movement usually occurs by action of the user or of
an external agent.
This subclass is indented under subclass 65. Device comprising an elongated boardlike member having a width
somewhat greater than a user"s foot and a normally upturned
leading edge adapted to support the user while planing across the
water surface while under tow.
This subclass is indented under subclass 65. Device comprising an elongated member of a width comparable to
the shoulder width of a user adapted to be propelled by a wave and
capable of supporting the user.
This subclass is indented under subclass 76. Device wherein an element is provided having a fulcrum point which allows
the element to move in and out of a working position in order to
increase the traction of the buoyant member.
This subclass is indented under subclass 76. Device wherein the buoyant member is a globe or disclike means
which supports, circumscribes, and rotates about the user as it
moves across the water surface.
This subclass is indented under the class definition. Device adapted to remove a person from the water from a position remote
from said person, to protect a person from the elements or hostile
marine life, or to sustain a person above the water for an extended

Note. These devices are normally recreational devices.
Note. Devices which comprise buoyant structures and are made
to simulate animals, fish, fowl, etc., or any part thereof, are
excluded from Class 441 if claimed to recite such simulating features,
and will be found in Class 472, Amusement Devices, particularly
subclasses 128+. If the buoyant structure only is claimed, classification
in Class 441 is proper.
