This class provides for the transfer of fluent material, gaseous,
liquid or flowable granular solids, through a flow confining system,
the source and terminal or receiver parts of which are normally
separable, i.e., one or both parts are portable or are otherwise
capable of or intended to have a utility in their separated condition. Such
utility ordinarily lies in portability of a separated part, either
for use of the contents material in another place, or for use of
one of the system parts with another complementary part. Each part
therefore must comprise an entity capable of use independent of
the other, and together the parts provide a flow path from a source
or dispenser to a terminal part or receiver, thereby comprising
a filling system.
This class takes a mere dispenser-receiver combination where
separability is claimed or is inherent, and also takes means to
deliver material to a receiver when there is claimed some system
characteristic which peculiarly relates the receiver to the dispenser
to define a coaction of one with the other to complete the dispenser-receiver relationship;
as for example, guiding or confining means for the receiver, related
conveying means for either the receiver or dispenser or both, or
a receiver support which is not merely a support for the dispenser
but is some member or modification beyond the structural requirements
The scope of this class does not include method and apparatus
for handling fluent material except in a manner characteristic of
fluid flow. For the most part the material supply processes and
apparatus involve discharge assistants and fluid flow guiding means
of the class of Dispensing (see References to Other Classes, below).
This class takes systems as above defined including receivers
which close (i.e., self-closing) upon separation or uncoupling from
This class also includes processes of varying gaseous conditions
in a vessel or container, i.e., evacuating or maintaining a vacuum
in a container, by sorption or gettering means incased in such container
where the claims are silent respecting any sealing off, or do not
include steps of closing and additionally where the sorption or gettering
is not of the kind provided for elsewhere.
This class also includes certain combinations and subcombinations
which appear to fall short of the receiver coacting means requirement
set out above, as in the last four "first line" subclass
groups of this class. Though they require no more than what might
be considered to be Class 222 subject matter, the concept of a normally detached,
readily connectable, dispenser-receiver relation (see I (2) above)

SECTION IV - GLOSSARY
The term as used in this class means some mechanically operative
element or device (not gas pressure) which arrests flow of material.
This term describes a filling system in which no operator
intervention is required from the time a receiver is placed in filling
position at least until the receiver is filled and ready to be removed.
The flow of contents material may be cut off by a movement of the
receiver which occurs in the sequence of events in the machine.
A mechanism which affirmatively effects or permits separation
of a portion of the contents material supply thereof and discharge
in a definite direction or path.
The portion of a dispenser or source part of the system which
comprises the flow outlet or flow confining terminus and other flow
confining structure which may be in advance (up-stream) of it back
to the supply.
A fluid handling device of increasingly restricted capacity
in the direction of flow and having its free end arranged to enter
into the inlet of a receiver, being ordinarily designed to collect
an unconfined flow and channel it into a narrower flow path or one
which is out of line with the previous path or flow direction. The
material may be retained in the funnel body by valve means, and
the funnel may comprise the only claimed supply means of the filling
system or an intermediate or final receiver, and may be supported
by either the preceding or succeeding flow confining means, or by
a means external to the flow system.
In order to draw a line with the manufacturing classes which
may include filling, the term is used here as meaning an operation
on material, or apparatus for operating on material, to effect a
permanent or irreversible change in the physical character of the
material, e.g. cutting, crushing, shaping and boring, or to arrange
the parts of an article of manufacture into their desired relation,
Means other than funnels to direct material from supply to
receiver without forming a flow-confining connection between them.
Examples of material guides in this class are: (1) A nonflow support
for contents material associated with a receiver support over which
the material can be pushed or moved manually into the receiver;
(2) A flow directing detachable extension of a receiver inlet which
may be either tubular or channel-shaped in cross-section. If tubular
and tapering, it must either engage the receiver externally or be
located entirely within the receiver. Cf funnel, above; or (3) An
extension of a supply container which is hand held, the extension
being designed to engage the receiver and direct the flow thereto.
A device which accepts the material from the dispenser and
is capable of confining fluids within
a predetermined or predescribed volumetric configuration, and does
not therefore rely upon surface tension or molecular cohesive forces
to preclude escape of material therefrom.
The contents material confining means of the dispenser.
The combination of dispenser and receiver in flow exchange
relation with any or all appurtenances thereof.
With respect to the treatment classes, treatment as here construed
is concerned with reversible changes in the physical characteristics
of contents material such as exemplified by agitating, heating,
cooling, sorting and the like.
Note. All patents containing method claims drawn to the method
of operation of any of the systems or parts thereof involved in
the class are included in this and the indented subclasses, but

reference to apparatus for use for a siphon bottle filling is required,
e.g., a claimed support or guide means for the siphon bottle, combined siphon
bottle valve operator and bottle holding arrangement, interacting
fill valve and dispenser operators, or siphon bottle dispensing
nozzle and means to press the said nozzle to a filling pipe.
for other apparatus for filling or refilling dispensers,

recognized as a dispenser, or claimed as having features of utility
only in connection with receivers of the dispensing type.
Note. For classification in this subclass there must be claimed
a receiver with some dispensing part which cooperates with the filling
means or there must be dispenser structure (other than force-producing
means confined to a fountain applicator) claimed, the reverse operation
of which assists in the filling thereof.
Note. This subclass and those indented thereunder may define
the characteristics of the receiver-dispenser and not necessarily
the supply means.

Note. The speed of the rotary movement must be sufficient
to impel or distribute the material by a positive motion as by throwing
or accelerating gravity flow.
Note. There must be an action on the contents material for

Note. Tire inflation with gas alone is not specifically provided
for in this schedule but the patents relating to the combination
with the source of supply of the inflating fluids have been distributed
in appropriate subclasses according to the means for causing the

This subclass is indented under subclass 37. Apparatus in which the filling means for the nongaseous
content material is controlled by or operates as the result of the
establishment of a desired gas condition in the receiver.
Note. This includes equilibrium conditions as well as those
in which there is a condition responsive means controlling the operation
of the filling means provided that positive flow control means is included,
such as valves or servo operated discharge assistants. Flow by barometric
or vacuum influences is not sufficient to cause classification in
this subclass, and equilibrium conditions in which the vent is closed
by float or pressure are not included.
This subclass is indented under subclass 39. Apparatus in which the establishment of a desired gas condition
in the receiver is controlled by the level of contents material
other than the gas in the receiver.
Note. The apparatus here included does not necessarily predicate
an air tight connection with the receiver, but rather requires a
change in the gas condition in the receiver by some outside interference.
This subclass is indented under subclass 40. Apparatus in which air is supplied to the receiver by an

or chamber is provided in which the gas is separated from the other
Note. A mere enlargement of a vent passage, whether for overfill

of diverse fluid systems must be present, as filters, gas separating
baffles, pressure equalizing means or pumps, separate outlets for
gas and liquid, etc.

one of the diverse fluids is used in the apparatus to seal joints
or to operate valves or other moving parts of the system.

occur other than or in addition to the displacement of gas from
the receiver by the nongas material, or the control of a single gas
flow to or from the receiver is operated during the cycle of filling
the receiver in some way other than by merely turning it on and/or off.
The special operation may involve repeating any gas control operation,
changing pressure or quantity, shifting the gas supply to another
use, or changing sources during the filling operation.
Note. Manual operation of the gas control apparatus is not
included even though the sole disclosure is that repeated operations
for the same receiver occur.
Note. Apparatus which during the cycle changes the gas condition
to change the equilibrium requirements of the system is included.
This subclass is indented under subclass 47. Apparatus in which the gas cycle which is characteristic
of this group is used to pretreat either the receiver or the contents
Note. This cycle is distinguished from mere counter pressure

the fact that some step intervenes which either changes the gas
condition or replaces one gas with another prior to the filling
This subclass is indented under subclass 47. Apparatus in which a source of pressure, either positive

of at the end of each filling cycle, as to atmosphere, to the supply
or to the next receiver. It may also be stored in the succeeding
receiver during the filling cycle.system includes a chamber for
storing the gas displaced from the receiver.
for filling means or heads having multiple passages,
one of which usually comprises a vent which provides for the passage
of gaseous material to or from a receiver being filled under atmospheric
pressure conditions or conditions indistinguishable from such. Sequential
operation of the valves for gas and nongas materials is not considered
significant except in lateral travel filling assemblies.
This subclass is indented under subclass 37. Apparatus in which means for removing the gaseous contents
of the receiver is combined with or comprises means for filling
the receiver with a nongaseous material.
Note. Apparatus claiming evacuation means broadly is included
if a cyclically operating machine having no other means for transferring
the nongaseous material is claimed.
This subclass is indented under subclass 37. Apparatus in which registering head and receiver means have
a lateral motion during the filling of the receiver.
Note. Filling systems having only one gas passage per filling
head are included if they are of the successive receiver, lateral
travel type, since different vents are in different stages of operation
at any one time.
This subclass is indented under subclass 63. Apparatus in which the receiver has been filled with a nongaseous
material prior to the gas treatment.
Note. The apparatus has features which lack utility except
when the receiver is filled with nongaseous material, such as means
for holding or compacting such material, or for mixing the gas with
it, as by agitating or by injecting the gas below the surface of
This subclass is indented under subclass 67. Apparatus in which the receiver is a valve bag, i.e., a
bag having an inlet in the folded corner thereof, the corner usually

involving valve bags.
This subclass is indented under the class definition. Apparatus in which the material contents is subjected to

This subclass is indented under subclass 69. Apparatus in which the density of the fluent charge in the
receiver is increased (1) by compacting or agitating within the
receiver or (2) by increasing the density of the contents charge after
it has been separated from the supply, the material being confined
until it enters the receiver.
Note. Deaerating of fluent materials is considered a compacting
Note. The many discharge assistants and agitating type dispensers
which inevitably produce a compaction of loose material as an incident
to handling have not been made a basis for classification in this
class but have been cross referenced to appropriate subclasses in
Class 222, Dispensing.

This subclass is indented under subclass 71. Apparatus in which the material is supplied to the receiver
in charge form, the charge having been compacted in a dispensing
type trap after separation from the source and handled subsequently

only, i.e., the specific end configuration must be set out, not
a mere statement that it is a coupling. Screw threaded or friction
held couplings are not considered sufficient for classification
in this class in the absence of a claimed receiver-dispenser combination.
Note. Most of the patents in this and the indented subclasses
relate to hand held and supported supply means of the grease gun
type. The receiver and supply securing means is not intended to
be a coupling means whereby the supply means after coupling is supported
by the receiver but rather a pressure retaining connecting means.
This subclass is indented under subclass 383. Filling apparatus in which the coupling securing means is
in the form of a rotatable terminal sleeve like element which has
freedom of movement with respect to a supply conduit means generally
about the longitudinal axis thereof.
This subclass is indented under subclass 383. Filling apparatus in which the coupling securing means comprises
a fixed jaw-like member and a movable jaw- like member, the receiver being
clamped between the said jaws.
This subclass is indented under subclass 383. Filling apparatus in which the coupling securing means is
defined by a flange-like element or finger which is adapted to grip
or slip over some suitably arranged fixed abutment or groove on
This subclass is indented under the class definition. Apparatus comprising means either encompassing or entering
a receiver or receiver inlet means for the purpose of maintaining
the said receiver against spillage, rupture or any other unwanted
collapse during the filling thereof.
Note. The patents forming this subclass generally relate to
subcombinations of the class subject matter, i.e., without filling
means; however, disclosed in a filling organization for the purposes
set forth above and not otherwise classifiable.
MATERIAL GUIDES OR SUPPLY WITH RECEIVER SUPPORTS (I.E.,
AIDS TO MANUAL FILLING):
This subclass is indented under the class definition. Filling apparatus comprising supply guide or supply containing
means having receiver supporting means arranged as an aid to manual
filling, gravity flow not being involved, but rather, mere hand
placing or dropping into the receiver.
