Abstract
251,443. Berk, F. W. May 15, 1925. Movable-abutment type. - In Roots' blowers wherein the rotors are driven through timing-gear and do not contact with each other or the casing. each rotor has three, four, or five hollow or semi-hollow wings R made in one piece. To facilitate setting the rotor in manufacture, indents, apertures R<1>, or projections are formed in or on its ends, and at the meeting faces when the rotor is formed in sections: The rotor may be made in one with or separate from its shaft, S. The wings R and boss R<2> may be constructed as generated teeth.
