DEFINITION

Classification: 15/104.05

Devices for cleaning the inside of the conduit, pipe, or tube.

(1) Note. See classes 29, Metal Working, subclass 81 and 122, Liquid Heaters and Vaporizers, subclass 379.

(2) Note. This group of subclasses will take devices for removing material in hardened form from tubes, pipes and tubular chambers, where the device is not a built-in arrangement, and where the implement is a brush or wiper, and as to scrapers and cutters, this class will take all those in which the tool has a rotary and/or reciprocating motion together with motion along or parallel to the axis of the chamber being cleaned.Class 214, Material or Article Handling, has related devices using implements of types not provided for in this class (15) and has scraper or cutter implements not having the motions provided for above, including endless belt type cutting or scraping implements. Class 214 further takes the scraper or cutter devices provided for in this group of subclasses when such devices are combined with a conveyor in addition to the scraper or cutter, but scrapers or cutters which have an incidental conveying function (e.g., reamers) will be found in this class (15). Class 214 further provides for devices designed for charging in addition to discharging material from chambers.Where the device for removing hardened material from the chamber is claimed as associated permanently with it so as not to be adapted for use on other chambers, the device has been classified on the basis of the character of the chamber.For devices and processes of this type, see, for example, 122, Liquid Heaters and Vaporizers, subclass 379; 196, Mineral Oils: Apparatus, subclass 122; 202,

Distillation: Apparatus, subclass 241; 208, Mineral Oils: Processes and Products, subclass 48; and 165, Heat Exchange, subclass 95.

(3) Note. For apparatus for cleaning smoking devices by use of a current of air or other gaseous fluid, see Class 131, Tobacco, subclass 244.
