Abstract

609,108. Gear-wheel pumps. BROWN & SONS (HUDDERSFIELD), Ltd., D., and TUPLIN, W. A. March 6, 1946, No. 6940. [Class 110 (ii)] The pumping chamber is divided up into two or more compartments by pairs of discs g, g<1>, having flats h, the pairs f, f<1> of meshing spur gears having their teeth staggered relatively to one another to reduce pulsations in delivery. The gears f are secured on the spindles e, e<1>, but gears f<1> are arranged to be an easy fit on keys i.
