(under the class definition) Apparatus including means operable for a portion only of the stroke of the working member, said means being effective to cushion the movement of such working member over the portion of the stroke in which it is effective.
(1) Note. A device (e.g., spring) which is effective over the entire stroke of the working member to urge the working member in one direction of its movement is excluded from this subclass.
