Class 254
IMPLEMENTS OR APPARATUS FOR APPLYING PUSHING OR PULLING
FORCE
Class Definition:
This class includes implements or apparatus for applying a
pushing or pulling force directly to either (a) an object to
be moved, or (b) a generally stationary object upon which
pressure or tension is to be exerted. It comprises jacks
(including lifting jacks, floor jacks, and analogous
implements), extracting apparatus (including stump pullers
and nail extractors), tensioning apparatus (including belt,
carpet and wire stretchers), hoist trucks, and cable-type
load hauling or hoisting apparatus. Also included in this
class is the subcombination of a cable guide which (1) is a
component of, or used in combination with, an implement or an
apparatus of this class, and (2) is intended to guide a cable
which is directly connected to either the object or an
object-supporting or -engaging member.
This class does not include the power-applying elements of
machines, such as pump or presses, nor the adjusting elements
of articles such as tables and chairs. It may, however,
include supports of general application not elsewhere
classifiable when they comprise means for hoisting the
load-carrying portion of the support.
Implements for performing compressing operations upon
material, e.g., clamps and bundling devices, are excluded,
also devices for merely grasping or engaging with something
to be moved.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Pushing or pulling implements of the jack or crowbar type,
including those having special engaging features which engage
between spring elements only, will be classified in Class
254. Those implements which engage between a spring and other
structure to move or guide the spring into assembled or
disassembled position will be classified in Class 29,
subclasses 700+.
Patents that disclose a general use and state the implement
can be used on an engine valve spring whether they coact with
other structure for assembly or disassembly will be grouped
as an art collection in Class 29, subclasses 215+.
Patents to an implement for spreading elements of a leaf
spring are classified in Class 81, subclass 3.7.

APPARATUS FOR HAULING OR HOISTING LOAD, INCLUDING DRIVEN
DEVICE WHICH CONTACTS AND PULLS ON CABLE:
This subclass is indented under the class definition.
Apparatus for transporting or shifting the object in its
entirety from one definite position or location to another,
including a driven device which contacts and pulls on a
segment of a cable when the object is transported or shifted,
and further wherein either (1) the segment of the cable is
attached to (a) the object, or (b) a structure which supports
the object, and is shifted with it from one location or
position to another, or (2) the device pulling on the cable
is attached to (a) the object, or (b) a structure which
supports the object and travels along the length of the cable
with the object from one position or location to another.
(1) Note. For an object transporting or shifting apparatus
to be proper for this and the indented subclasses, at least
one segment of the cable should move relative to a
cable-contacting component of the apparatus, (e.g., cable
wound or unwound by a drum, cable pulled by driven device
over a pulley spaced therefrom, etc.), when the object is
shifted or transported from one location or position to
another; classification is elsewhere in this class if the
cable acts as a simple link between the driven device and the
object being pulled, (e.g., subclasses 93, 95, 98, 120,
etc.).
(2) Note. The driven device and cable structure classified
in this and the indented subclasses is that which is at least
disclosed as either being used to (1) transport a load which
is removable or detachable from the driven device, cable, or
supporting structure attached to the driven device or cable,
or (2) bodily shift an entire article, such as an anchor,
between two definite positions. On the other hand, if the
cable and its driven pulling device are disclosed as being
used only to (a) apply a force between elements of a machine,
such as a pump or a press, (b) transmit force to operate a
mechanism from one to another of its positions, such as a
railroad hand-brake operator, (c) apply a force to adjust a
portion of an article or apparatus relative to another
portion of the article or apparatus, such as an awning
operator, or (d) transmit force from a force input point to a
force output point, such as a drive pulley and belt,
classification is elsewhere, (e.g., Classes 74, 242, or the
appropriate structure class). In the absence of any
disclosure as to the use contemplated for the cable-pulling
device, classification is in some other class based on other
details of the invention or in Class 242 based on details of
a cable winding or unwinding drum structure or the winding of
the cable onto a drum.
(3) Note. The claimed combination of the subject matter
appropriate for this subclass (see (2) Note of this subclass)
and means which is intended to continually contact and
restrict or guide the movement of the object (or the
structure which is connected to the driven device or cable
for supporting the object) to a fixed path of travel, is not
proper for this and the indented subclasses and
classification is in subclass 387 of this class or elsewhere,
(e.g., Classes 74, 104, 187, etc.).
(4) Note. A wheeled roadway or railway vehicle having a
cable hoist mounted thereon and a load supporting portion for
receiving the load from the hoist is classifiable in Class
414, subclasses 467+. A cable or rail guided wheeled carrier
which travels in a small restricted area, (e.g., a warehouse)
and has a cable hoist mounted thereon is classifiable in
Class 212. A wheeled carrier or vehicle capable of readily
traveling outside a small, restricted area (e.g., highway
truck, railway car) and having a cable hoist mounted thereon,
which hoist does not transfer a load to a load supporting
portion of the carrier or vehicle and is fixedly mounted on
the carrier or vehicle, is not considered to fall within
either of the above categories and is classifiable in this
subclass (264) and the indented subclasses.
(5) Note. A wheeled roadway or railway vehicle having a
motor powered, traction cable pulling device mounted on it,
for propelling it from one point to another as the cable is
pulled by the device, is found in either Class 180, subclass
7 or Class 104, subclasses 173+; if, however, the vehicle is
not claimed or the device is disclosed as also being used to
pull a load, classification is in this class (254). A
traction cable pulling drum which is adapted to be secured
directly to one of the wheels of a roadway or railway
vehicle, and which pulls on the cable as the wheel is rotated
to provide additional vehicle moving force, is found in
Classes 74, 104, 180, 242 or 280. A traction cable pulling
device which is not supported by the vehicle, but which
propels it between one location and another, is found in
either Class 254, when the vehicle is claimed broadly as a
load or in an appropriate class, such as Class 104 or Class
280, when the vehicle is claimed in detail.
(6) Note. The term "cable" is used in this and the indented
subclasses to designate a flexible, elongated, hauling
element, such as a rope, chain, wire or a flat band.

Device includes rotatably driven, cable contacting drum:
This subclass is indented under subclass 264. Apparatus
wherein the device includes a drum which is driven about an
axis fixed relative to at least one other portion of the
apparatus, the drum having a perimeter which contacts the
cable and winds a segment of the cable around the drum's axis
of rotation, or otherwise engages and pulls the segment of
cable, when the object is transported or shifted.
(1) Note. The term "drum" is used in this and the indented
subclasses to designate a rotatable structure, (e.g.,
capstan, driven pulley, driven sprocket wheel, gipsy,
spindle, spool, wildcat, winding drum, windlass, etc.), which
is caused to turn about an axis of rotation by a drive source
and which has a perimeter for contacting and pulling on a
cable, whereby a driving force is transmitted from the
source, by way of the drum and cable, to the load.
(2) Note. In order to avoid the scattering of art of a
related nature, it has not been possible to require that the
drum always be claimed significantly for classification in
this and the indented subclasses. Rather, the structure
recited may be only minimal, (e.g., a projection on the drum,
a bearing face at its axis) in some instances, or, in the
extreme, the drum may appear only nominally in the claim,
(e.g., the mere locating of it relative to another part of
the haulage system, such as a cable guide pulley or a drive
means for the drum).
(3) Note. Cable reeling devices which are used to lower a
gravity influenced load by retarding the rotation of the
cable reel or the movement of the cable wound thereon, but
which do not have reel rotating power means capable of
shifting the load either upwardly or horizontally, are found

ANTIFRICTION MEANS FOR CABLE PULLING DRUM:
Apparatus under pulling haulage cable in which friction
diminishing means, (e.g., bearing, provision for lubrication)
is provided between a cable pulling drum and the structure
which supports it for enhancing the capability of the drum to
rotate about its axis by reducing the frictional resistance
thereto.

YIELDABLE, CONSTANT ENGAGEMENT, FRICTION COUPLING, (E.G.,
SLIP CLUTCH) IN DRIVE FOR CABLE PULLING DRUM:
Apparatus for pulling on a load hauling cable including a
driven drum, the drive for the drum includes a coupling
having at least two members which rotate around a common
rotational axis and have a surface in constant contact with
that of the other cooperating member, the members normally
rotate together at the same rotational speed when
transmitting power to the drum due to the friction created by
the contact of their surfaces, however, if the torque on one
of the members exceeds an acceptable amount, or the amount of
force tending to push the contact surfaces of the members
toward each other is reduced, the contact surfaces will slip
relative to each other.
