DEFINITION

Classification: 416/131

(under the class definition) Apparatus comprising an impeller* or working member*, or a part thereof mounted (1) on a support by means of a joint or a yielding or elastic connection or (2) as to be capable of self movement due to the effect of dynamic forces thereon (e.g., rotary motion or working fluid*).

(1) Note. Mere working member composition of flexible material is not included; however, a flexible joint or connection permitting articulation or "controlled", shifting of a working member or part is included.

(2) Note. This definition does not include mere direct movement between an operative and inoperative position of an impeller or working member.

SEE OR SEARCH THIS CLASS, SUBCLASS:

87+, for a working member which moves radially outward relative to its rotation axis in response to dynamic forces exerted directly thereon.
