At the same time the motion of the slide shifts a friction roller on its driving disk so that the governor speed is increased relative to the engine causing an additional motion of the slide in the same direction. As a result, the governor slide is given a greater motion for a given change in speed than would otherwise result."}, {"label": "Description", "content": "Reference:"}, {"label": "Description", "content": "This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A.
