    Abstract: 288,046. Marks, E. C. R., (Simplex Refining Co.). May 10, 1927, Distilling plant; rotary pumps; movableabutment type; packing; mounting and supporting; driving.-In a vacuum condensing plant, suitable for the distillation of petroleum oil, liquid is drawn from the plant by a pump housed in a tank having sufficient liquid therein to seal the pump against ingress of air. The vacuum in the condensing chamber 100 is maintained by a vacuum pump 116 and the condensed liquid is drawn from the lower chamber of the condenser by a gear pump shown in more detail in Fig. 2. The pump 34 is carried by an open cylindrical frame 26 supported from a base plate 12 on which the driving motor is mounted. The enclosing tank 15 for the pump is also supported from the base plate 12 and is provided with a discharge opening 21 at such a height that the pump is submerged. The drive is through bevel gearing 80, 77 with a sliding joint between the gearing shaft 69 and pump shaft 48. A valve 95 controlled by a hand lever 97 is provided in the conduit 61 leading from the condenser and is also submerged in the liquid.
