(under the class definition) Device not provided for in the above subclasses.
(1) Note. Patents directed to particular runner* structure but properly assignable to Class 415 have been placed in the Class 415 schedule, where most appropriate (note, in particular, subclasses 182.1+), and have been cross referenced to Class 416. See section IV of the Class 415 definitions for a discussion of class lines.
SEE OR SEARCH THIS CLASS, SUBCLASS:
182.1+, for a device comprising working fluid passage or distributing means for a runner* (e.g., casing*, etc.). Note, in particular, subclasses 216.1 with specific shaft* shape or material, 217.1 with runner having corrosion resistant or nonmetallic portion, and 218.1 with runner having conical hub including small diameter facing upstream.

416, Fluid Reaction Surfaces (i.e., Impellers), for particular runner structure.
CROSS-REFERENCE ART COLLECTIONS
The following subclasses are collections of published disclosures pertaining to various specified aspects of the rotary kinetic fluid motor* and pump* art which aspects do not form appropriate bases for subclasses in the foregoing classification (i.e., subclasses superior hereto in the schedule). Only cross-reference patent copies reside in the cross-reference art collection subclasses; these subclasses do not contain "original" patent copies. These subclasses may be of further assistance to the searcher, either as a starting point in searching this class or as an indication of further related fields of search inside or outside the class. Thus, there is here provided a second access for retrieval of a limited number of types of disclosures. (1) Note. Disclosures are placed in these subclasses for their value as references and as leads to appropriate main or
secondary fields of search, without regard to their original classification or their claimed subject matter.
(2) Note. The disclosures found in the following subclasses are examples, only, of the indicated subject matter, and in no instance do they represent the entire extent of the prior art.
