for.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
In the class definition above, regarding vertically swinging
booms, apparatus having a vertically swinging boom comprised of
relatively movable segments and disclosed as having a self-loading
load engager (e.g., a backhoe or steam shovel) are self-loading
apparatus and should be considered for Class 414, Material or Article
Handling. (Note, however, that in accordance with the other part
of the class definition, regarding load engagers, if the load engager
is suspended by a flexible member, the apparatus is proper for Class
212.)
The "lateral shifting" criterion specified
in the class definition requires more than merely supporting a hoist
on a wheeled vehicle to render the hoist ambulant. See search notes
to Class 254 below.
As indicated in the general search notes below, many classes
provide for traversing hoists of specific application, which generally
include but are not limited to those patents which claim load engager
structure peculiar to the specified application.
Static Structures (e.g., Buildings),
subclasses 111+ for a rigid elongated member, a section of which
is movable relative to another section or a base, and mechanical
motive means to effect such movement; subclass 632 for a passive, axially
extensible elongated member; and subclasses 633+ for the
specific structure of an elongated rigid member, per se. Class
212 is the residual locus for combinations of a load-handler boom
and a sluing or luffing mechanism therefor. Class 212, subclasses
347+, contain patents to boom structure, per se, where
structure peculiar to load handling is recited (e.g., cable guide,
chafing strip, etc.).
Railway Rolling Stock,
subclass 163.1 for overhead crane trucks (trolleys). Hoisting means
or structure peculiar thereto must be claimed for original placement
in Class 212.
Cleaning and Liquid Contact With Solids,
subclasses 76+ for cleaning apparatus of the Class 134 type claimed
in combination with a traversing hoist to transfer the work.
Elevator, Industrial Lift Truck, or Stationary Lift

thereof (e.g., forklift) and subclasses 240+ for transportable
elevator.

and shift it laterally, subclasses 266+ for hoisting drum
features, and subclasses 389+ for cable guide structure.

nature of a hoist line bucket; subclass 191 for the charging of
a chamber of a type utilized for a heating function by means of
a driven device for transporting material to and/or into, or
into and within, the chamber, and wherein the device comprises a
traversing hoist having a material-underlying support or a material-attracting
and gripping means; subclasses 391+ for the combination
of a driven device external of a wheeled, load-transporting type
vehicle for raising or lowering a load which is to be taken from
the vehicle, and the vehicle being unloaded thereby; subclass 399
for the combination of a device external of a wheeled, load-transporting
type vehicle for raising or lowering a load which is to be moved
to the vehicle, and the vehicle being loaded thereby; subclasses
486+ for a self-loading or self-unloading vehicle having
a load-receiving portion which is pivotable relative to the horizontal, and
wherein the vehicle has means to raise a load above said portion
for deposit thereon or therein, by way of further explanation, a
self-loading or unloading vehicle of that class (414) handles only
a load being moved to or from the vehicle; subclasses 540+ for
a self-loading or unloading vehicle having a load-handling means
which raises or lowers a load in a path which includes vertical,
rectilinear movement; subclasses 560+ for traversing hoists
combined with additional material-handling means; subclasses 564,
569, and 571 for hoists combined with additional material-handling
means; subclass 591 for apparatus having a self-loading grasp suspended
below a boom or bridge for guided vertical movement; subclasses
592+ for a hoist with loading or unloading means; and subclasses
680+ for vertically swinging load supports. Class 414
takes the following patents to apparatus having means to raise a
load and shift it horizontally:
Those which specifically claim a self-loading engager
(e.g., bucket, fork, grab, magnet, etc.) which is not suspended
by a flaccid member.
Those which disclose a self-loading engager only and claim
a vertically swinging boom comprised of relatively movable segments.
Those which claim the vehicle portion of a vehicle-mounted
hoist which is disclosed solely for loading or unloading the vehicle,
with the exception of those patents claiming means to facilitate
assembly and disassembly of the traversing hoist from the vehicle
(Class 212, subclasses 180+).
Those which claim a separate load-transporting vehicle which
is to be loaded by the hoist (as disclosed).
Those which are claimed in combination with additional handling
means not of the Class 212 type.
