It will be seen that the eccentric-rod may be readily adjusted longitudinally to con trol the action of the valves of an engine and to position the saine properly, and that the connection obviates the necessity of removing the eccentric-rod from an engine to lengthen or shorten it. It will also be apparent that the connection is-strong an d durable, and that the parts are rigidly held in theiradjustinent.
