Class 068
TEXTILES: FLUID TREATING APPARATUS
Class Definition:
This class is the class of machines, implements and
accessories for fluid treatment of textile fabrics, textile
fibers, and pulp as for the purpose of carbonizing,
bleaching, dyeing, moistening, mercerizing or mordanting the
same or for the removal of dirt, grease, soil, and other like
substances from them by the use of solvents, saponifiers or
emulsifiers, unless specifically provided for elsewhere.
The machines of this class have been divided into the
following types:
Gas, steam, or mist treating. These are machines for
subjecting a textile to a fluid in the form of a gas, steam,
or mist.
Scrubbing. These are machines for effecting treatment of
textiles, while saturated with a liquid, by reason of a
sliding action taking place between the textiles and a
contacting element, during which action the textiles may be
kneaded or brushed. Scrubbing may be effected by the use of
a pair of cooperating rolls if they rotate at different
peripheral velocities or rotate in the same direction.
Generally, scrubbers have a squeezing effect which is
incidental to the scrubbing action.
Squeezing. These are machines for effecting treatment of
textiles, while saturated with a liquid, by reason of
application and release of pressure on the textiles.
Impulsing. These are machines for effecting treatment of
textiles, while immersed in a liquid, by causing an
intermittently movable element to impart repeated impulses to
portions of the textiles as distinguished from the entire
mass, such that the textile portions will travel a distance
independently of the moving element.
Dragging. These are machines for effecting treatment of
discrete portions of the entire mass of textiles by causing
them to be engaged by and dragged around the tub with a
moving element, without the textile portions being clamped to
the element, while the textiles are submerged in a liquid.
Generally, the moving element is a pin or comprises fingers
or narrow blades. Where the entire mass of textiles is moved
within a tub or moved into and out of the tub in one
continuous cycle, as by rakes or conveyors moving the entire
mass, the patents are classified in the liquid flow
subclasses.
Tumbling. These are machines for effecting treatment of
textiles by causing them to be tumbled about in a drum or
cage which is mounted on a horizontal or inclined axis, said
textiles being submerged in a liquid during at least a
portion of the revolution of the drum or cage and being free
to move in the cage. The drum or cage must make at least a
360 deg. revolution, and may or may not have vanes, buckets,
or the like to cause a circulation of liquid within the
tumbler and may or may not have vanes to cause a rubbing
action within the tumbler.
Liquid flowing. These are machines for effecting treatment
of textiles by reason of the relative motion of a liquid and
the textiles as by the forcing of a liquid by pumps, by
centrifuging or the like through the textiles, or by the
shifting bodily of the entire mass of textiles through the
liquid with free access of the liquid thereto in
contradistinction to moving discrete portions of the
textiles, or by the agitation of the entire mass of both the
liquid and the textiles submerged in the liquid.
Liquid applying. These are machines for treating textiles
with liquid in which the textiles are subjected to an
application of liquid other than by being submerged in the
liquid or by being subjected to a vapor, spray, or mist.
NOTES
(1) PROCESSES:
Where both process and apparatus (for Class 68) for its
practice are claimed, the patent is classified in the class
appropriate to the process claimed and is cross-referenced to
this class for the apparatus. (Note: Where the Search notes
below are to processes, this is noted by a parenthentical
insert at the end of the note. Otherwise, the Search note is

(1) Note. See definition of impulsing in main class

The function of an impeller is to impart a force to the
textile so as to cause it to move a distance independently of
the impeller; the function of a drag or dolly is to move the
textile with the drag in its movement or movements.In
structure, the impeller, used is an impulser, is generally a
broad flat surface which may or may not be perforate, and
which has an intermittent movement. The drag or dolly
generally consists of a pin or plurality of pins or an open
grille work to cause textiles to move with the drag or dolly,
said drag or dolly having either a continuous rotary movement
or a reciprocating movement. Impulsers and drags are
distinguished from squeezing machines in that there is no
surface cooperating with the impeller or drag between which
surface and the impeller or drag the textiles may be
compresses.
