Class 294
HANDLING: HAND AND HOIST-LINE IMPLEMENTS
Class Definition:
This class comprises all devices combined with handles,
terminal elements, or attachments peculiarly adapted for
engaging supporting articles or materials for handling or
manipulating purposes and not structurally limited to any
classified art and such combinations thereof and accessories
therefor as not elsewhere classifiable.
(1) Note. This class includes power applying element which
relate to the engaging of the load and not to its movement
thereafter, except that a means for applying a straight line
force or push to the load after the load has been released
from the engaging means to move the load away from the
engaging means is classified in this class.
(2) Note. The addition of wheels to any type of handlers
included in this class, except where such addition is merely
incidental, (such as adding casters to hoisting buckets), is
held to involve transportation combinations.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(1) Note. This class does not include hoisting machines,
which are provided for in Class 414, Material or Article

(2) Note. For hand and hoist-line terminal implements and
attachments, classifiable on their necessary function in more
elemental classes, see particularly, Classes 24, Buckles,

(4) Note. For hand and hoist-line terminal implements and
attachments involving features additional to mere handling,
such as changing the shape or condition of the matter
engaged, see particularly Classes 37, Excavating, and 100,
Presses.
(5) Note. For power applying elements that relate to the
movement of the load see Classes 198, Conveyors:

the stuck object may be a mere pipe joint or coupling of
general utility such as a screw threaded joint. Such mere
joint or coupling is considered to be a "grapple" for
purposes of classification in subclass 86.34 but is not
considered a "grapple" for purposes of classification in any
other subclass under this definition.
(3) Note. The combination of a metal cutting means for
cutting away material around a stuck object and a retrieving

especially subclass 86.34. The combination of a broadly
recited washing means or earth cutting means for removing
matter around a stuck object is also included under this

(1) Note. The functioning of the "additional means" must
require a movement distinct from that of the grappling
operation. If, for example, a grapple is caused to be
engaged by an object by a downward movement and an inclined
surface on the grapple causes the object to move laterally
incident to the downward movement, then this definition is
not satisfied.

(1) Note. The "grapple" under this definition may be a mere
joint of general utility such as a screw threaded joint. See

(2) Note. A device under this definition is intended to
retrieve only a single, unitary stuck object. If the device
is adapted to retrieve a plurality of objects, such as junk,
it is excluded. Such devices may be found in numerous

specific recitation of earth cutting means causes
classification in Class 175 but a mere broad recitation of
