Abstract

347,246. Screw pumps. GOODALL, J. H. H., The Old House, Tickhill, Yorkshire. Jan. 20, 1930, No. 1866. [Classes 110 (i) and 110 (ii).] A pump comprises two or more intermeshing tapered screws, the threads of which are of concaved rectangular section. The threads may be of the same or opposite senses, and the screws are geared to rotate in the proper senses. Specification 23000/94, [Class 102, Pumps &c.], is referred to.
