DefinitionThis 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° 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 to Apparatus.) |
