Abstract

472,254. Pug-mills; screw-impellers. BARKER, R. P., and ELSTON, T. P. March 17, 1936, No. 7939. [Class 86] [Also in Group XXX] The impeller of a pug-mill is formed with a working face which in axial section is concave and has a thickened periphery 19 which shrouds the concavity 17. As shown, the rear face is straight; in other forms it is either concave or convex, and may have a collar forming an additional peripheral thickening.
