That the upper part of the grate bar will overhang the center on which it turns is the improvement claimed by the inventor."}, {"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.
