Specification of Letters Patent.

Application filed September 25, 1909.

Patented Mar. 12, 1912. Serial No. 519,548.

To all whom it may concern:

Be it known that I, ORVILLE W. ALPHA, a citizen of the United States, and a resident of Franklin, in the parish of St. Mary and State of Louisiana, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention is an improvement in pumps, and consists in certain novel constructions, and combinations of parts, hereinafter described and claimed.

The object of the invention is to provide an efficient pump of the rotary type, wherein the cylinder is caused to rotate at a high speed, the water being lifted by spiral wings or vanes, a portion of the distance, and by centrifugal force for the remainder.

Referring to the drawings forming a part hereof, Figure 1 is a perspective view of the improvement, the cover being removed. Fig. 2 is a vertical section of the cylinder. Fig. 3 is a plan view. Fig. 4 is a detail perspective View of one of the spider arms and Fig. 5 is a transverse section of the same.

The embodiment of the invention shown in the drawings, consists of a pump cylinder which is composed of a body portion 1, and a flaring upper end 2, which forms a mouth or outlet for the cylinder, and the said portions are secured together by rivets 3. The cylinder is provided in the flaring portion, and near the upper end thereof with a spider 4L, and a shaft 5 is clamped in the spider, the shaft being arranged coaxial with the cylinder. The lower end of the shaft is journaled in a step bearing 7, on the cross bar 8 of a frame to be presently described, and the upper end is journaled in a bearing, 10, on a second cross bar 9 of the same frame; near its upper end, the shaft is provided with'a pulley 11, having on the periphery thereof, a plurality of grooves 12, for receiving a belt or the like, to connect the shaft with a suitable source of power. The cylinder is also connected to the shaft by means of spiral vanes or blades 13, which extend from the lower end of the cylinder to the commencement of the flaring portion as shown in Fig. 2.

Each of the vanes is formed of a continuous sheet of material, having an angle plate 14 secured to each of the edges, one side of the plate being secured to the sheet. The other side of the plate on the outer edge is riveted, to the cylinder wall, while the other side of the plate on the inner edge is riveted to the face of a drum 15, having at each end a washer 15 encircling the shaft and pinned thereto by a pin 14*.

The frame before mentioned, consists of two end cross bars 16, and a central bar 8, the ends of the bars being connected by rods 17.

Uprights

18 and 19 are connected with the rods, the center upright 19 on each side extending above the end uprights l8, and the said center uprights are connected by the above mentioned upper cross bar 9. The uprights on each side of the frame are connected by the plates 20, which are secured thereto by bolts 21, and braces 22 are arranged between the upper ends of the uprights 19, and the lower ends of the adjacent uprights 18. The end uprights are also connected by cross plates 23.

. The flaring upper end of the cylinder ex tends through an opening in a trough 24, which is supported by the frame, the trough having one end open as at 25, and being inclined downwardly toward the said end, as indicated in Fig. 1.

The spider is composed of a plurality of strips, each bent to form two portions 26, at right angles to each other, each having at its free end an angular portion 27, and at the junction of the portion a recess which cooperates with the recesses of the other strips to form the bearing 6. The strips are arranged as shown in Fig. 3, and the lapping portions of the strips are secured together by rivets 28, to form the arms of the spider 4t, and the angular portions 27 are secured to the flaring part of the cylinder by rivets 29. As will be evident from an inspection of Figs. 3, 4 and 5 each of the spider arms is twisted on a longitudinal axis near its outer end.

The free edge of the flaring mouth of the cylinder is laterally flanged, as shown at 30 in Fig. 2, and a cover or hood 31 is arranged about themouth,the edge of the hood extending outside of the flange 30, the hood being secured to the frame and trough and acting as a splash head. The hood is also spaced apart from the edge of the mouth to permit the free flow of water out of the cylinder and into the trough. The trough is provided with an annular flange 32, encircling the opening 33, through which passes the cylinder, and the flange is reinforced by a collar 34L, arranged outside of the flange. The lateral flange 30 of the flaring part of the pump extends over and beyond the flange 33 of the opening through the trough, and the edge of the hood or cover 31 extends beyond the lateral flange, and the said edge is provided with a downwardly projecting flange 31.

It will be understood that the portion 1 of the pump cylinder may be of any desired length, and that the vanes 13 extend from end to end of the same. WVhen in use, the lower end of the cylinder dips into the water to be elevated.

In operation, the cylinder is rotated by means of the pulley 11, and the water is lifted by the spiral blades or vanes, and is passed upwardly into the flaring or frusto conical part, which may also be of any desired length. Owing to centrifugal force, the water tends to move outwardly, but is restrained. by the wall of the cylinder. When however the flaring part of the cylinder is reached, while the direct outward movement is checked, the water is deflected, and tends to move upward at an angle to its original direction. It thus passes up the flaring side of the cylinder until it reaches the upper edge, when it passes out into the trough. It will be evident that the improved pump is more cheaply constructed than one with a continuous spiral, and re quires no more power in its operation.

The fact that the flaring portion of the cylinder travels with the cylinder and the vanes, permits the pump to operate with less friction, than did it travel up a fixed surface.

It will be observed that in the improved pump, the liquid is drawn through the pump, and not through a separate casing, thus permitting the use of a shorter vane, and dispensing with the necessity of so much power.
