Filed: 1955-06-06
Abstract: 775,623. Centrifugal pumps. GORMANRUPP CO. June 6, 1955, No. 16173/55. Class 110 (1). A self-priming centrifugal pump comprises a partition dividing the pump casing into a pumping chamber and a combined discharge and separating chamber, the partition partly defining a priming passage leading from the lower part of the combined chamber into the pumping chamber, and partly defining a discharge passage of progressively increasing cross-sectional area leading from the pumping chamber into the upper part of the combined chamber, and the liquid-containing space in the pumping and combined chambers below the intersection of .the inlet conduit with the pumping chamber exceeding the combined liquid-containing space in the pumping chamber and in the priming and discharge passages whereby, when the impeller is rotated, the last-mentioned space will be filled with liquid.. A partition 20, Figs. 1 and 2, divides the pump casing into a pumping chamber 2 and a combined discharge and air separating chamber 3. Water discharged by the impeller 9 flows through the progressively widening space 17 between the partition 20 and the upper wall of the casing to enter the chamber 3 and finally flows to the outlet pipe 4. When the pump is stopped, the water in the casing drains out through the inlet pipe 5, down to the level of the lowest point of intersection of the pipe 5 with the casing wall; the latter may be cut away as at 27 to facilitate drainage. When the pump is started, the water remaining in the casing feeds through a passage 25 and a priming passage 26 to fill the chamber 2 and the discharge passage 17, thereby priming the pump. Instead of extending vertically, passage 26 may be inclined to the vertical or even be substantially horizontal. In a modification, the passage 26 is replaced by a hole through the partition 20. Alternatively, a gap is left between the casing wall and the right-hand end of the partition 20. In the pump shown in Figs. 6 and 7, the pumping chamber 48 and the combined discharge and air separation chamber 49 are separated by a radially extending wall 47 and axially extending walls 46, 56, the chambers being connected by a priming passage 55 formed between wall 56 and the bottom wall of the casing. Water is discharged through a passage 48a to an outlet pipe fitted into either one of two openings 51, 52. A tubular intake 43 extends horizontally but may instead be bent downwards so as to open through the bottom wall of the casing.

Filed: 1921-06-13
Abstract: 165,395. Plasschaert FrÞres, A. & H. June 23, 1920, [Convention date]. Cylinder and like machines.-In pigeon-timing apparatus wherein the time impression is effected by means of a roller which traverses guides and presses the record-strip against a dial plate as described in Specification 19131/05 [Class 101, Printing other than letterpress, &c.], the roller is brought into operation by a winch mechanism having mutilated gearing to effect the automatic release of the roller, and the guide or runway for the roller is formed with double straight grooves. The printing roller 13 is mounted in bearings 14 carried by a chain 15 the upper end of which is secured to a drum of a spring barrel 16 while the lower end is attached to a drum 17 and in the initial position as shown in Fig. 1 is completely unwound therefrom. The operating-crank is mounted on a shaft 21 which carries a mutilated gear-wheel 19 adapted on rotation to turn a gear wheel 24 to wind up the chain on the drum 17. The shaft 21 also carries a single toothed wheel 25, Fig. 7, adapted to engage the teeth of a wheel 27 mounted on a shaft 28. During the winding of the chain on the drum 17, the roller 13 is carried along in the upper groove 37 of the runway 32 and the movement causes a raising of the inclined upper length of chain and a pressure to be exerted by the bearings 14 on the runway. At the end of the movement the roller assumes the position shown in Fig. 6, and at the same time the gear wheel 19 releases the gear wheel 24 whereupon the chain and roller, under the action of the spring drum 16, return to their normal position traversing the lower groove 38 of the runway 32. During this movement the roller exerts a pressure on the paper strip 33 so as to press it against the dial plate 34. To ensure that the roller traverses the right groove in its forward and return movements the ends of the runway are bevelled as shown at 35, 36. The pressure exerted by the roller in pressing the paper strip against the plate 34 may be regulated by adjustably mounting the roller guides.
