DEFINITION

Classification: 416/204

(under the class definition) Apparatus comprising means for attaching a working member to a mounting such as a hub or shaft.

(1) Note. A specific recitation of the attaching means is required in a claim for placement in this and dependent subclasses, the mere claiming or "means for connecting the blade to the support" or similar broad recitation not being sufficient for original classification.

(2) Note. Packing or sealing members, per se, between the blade and its mounting do not comprise blade attaching means.
