This class contains patents involving means for connecting
together the various elements of a railway train. It also contains
patents involving means for resiliently absorbing the shocks and
blows incident to the movement of the train and to give cushioning
effect to starting and stopping thereof. Devices relating to this
purpose may be formed as a part of the coupling devices or may be
separate devices secured to or built into the car construction,
either to cooperate with the coupling device or to engage and cooperate
with similar structure on another car.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(1)
Note. Elements of a car, which are also elements of the subject
matter of this class, but are modified in structure for use in combination
with other elements of the car, the problem involved being more
that of car construction than relating to the subject matter of
this class, will be found in Class 105, Railway Rolling Stock. Copies
of the patents in Class 105 which might be of value as references
in this class have been placed in the class as cross references.
(2)
Note. Patents claiming combinations between car couplers and
devices for other purposes incident to the use and operation of
the car will be found in the classes in which such other devices
are classified. The combination of a car coupler and means for
coupling train-pipe service for air or steam forms an exception
to the rule above noted and will be found in this Class 213, subclass
76. However, where such train line is secured to a coupler or drawbar and
its operation is the same as though hung to any other part of the
car the combination will be found in Class 285, Pipe Joints or Couplings,
subclasses 24+ and 62+. The combination of a
car coupler and connecting means for electric circuits forms another
exception to the above rule and will be found in this Class 213,
subclasses 1.3+. Where the combination is between a coupler
and a brake see Class 188, Brakes. Where the combination is between
a car coupler and means for unloading or loading a car, see Class
