Abstract

535,554. Rotary engines. GENERAL MOTORS CORPORATION. April 18, 1940, No. 6999. Convention date, April 22, 1939. Drawings to Specification. [Class 110 (ii)] The lobes and end walls of the rotors of a Roots' blower are provided with surfaces of readily abraidable material which are rubbed down to secure minimum clearances by a preliminary running-in process. Alternating, the casing may be provided with such surfaces. The abraidable material may be sawdust, ground cork, corn meal, cotton, rayon, ground synthetic resins or hard rubber with a varnish or suitable binder.
