Description: |
| Abstract:
This invention relates to pumps, and particularly to rotary pumps.
The object of the present invention is to provide an improvement in pumps in which there is a rotary impeller cooperating with eccentrically mounted independently oscillating impeller blades in combination with a casing concentric with the center of the impeller blades, and within which the rotor is eccentric; and a further object of the invention is to provide means for reducing the friction of the parts.
Another object of the invention is to provide a safety trap or yieldable wall section for receiving large solid pieces which may be drawn into the pump, and thereby save the parts from breakage or other injury.
Claims:
A rotary pump including a pump cylinder, a removable head therefor having a tubular inwardly projecting hub, a solid shaft extending eccentrically through the tubular hub and supported in the removable head, a rotor fixed to the shaft and having an annular flange, said flange having roller bearing chambers closed at their inner ends only, a roller bearing in each chamber adapted to be dislodged through the outer end only of the chamber, the removable head abutting the annular flange of the rotor and normally closing the opened ends of the roller bearing chambers to retain the roller bearings from dislodgment, impeller blades supported on the tubular hub of the head for rotation and projecting through the roller bearings, induction and eduction ports in the pump cylinder, and means for securing the removable head and rotor in place.
This patent was improved with patent #1,187,628.
