ROTARY PUMP.

Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed February 21, 1906. Serial N 0.. 302,276.

T 0 all whom it may concern:

Be it known that I, JAMES JOSEPH ODoN- NELL, a citizen of the United States, residing at Paducah, in the county of McCracken and have invented a new and useful Rotary Pump, of which the following is a specification.

This invention relates to centrifugal rotary pumps, and its object is to provide a 3 simple and compact device of this character particularly designed for use in pumping out barges. I

Another object of the invention is to provlde a pump so constructed as to practically prevent all vibration of the parts during the operation of the pump, there being a sectional drive shaft and a sectional outlet pipe used in connection with the pump, said sectional pipe carrying a motor for actuating the pump. 1

With these and other objects in view the invention consists of certain novel features combinations of parts which will be hereinafter more fully described and pointed out in the claim.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a diagram showing a number of barges or scows in tow, each of the severaL barges being equipped with a pump and all of sa1d pumps being provided "with flexible means whereby power may be conveyed thereto from the tug boat. Fig. 2 is a vertical sectional view of a pump in connection with the system. Fig. 3 is a horizontal sectional view taken on the line A-B, Fig. 2.

Referring to the figures by characters of reference, BB designate a plurality of barges or scows in tow of a tug boat T, said barges and tug boat being flexlbly connected in the usual or any referred manner so as to be capable of in epen'dent movement laterally one another. barges is provided with a pump designed to be actuated'by power generated upon the tug boat T. In the present instance a .dy-

namo D has been indicated upon the tug boat and the same has been shown connected by means of wires with a'motor M located upon each barge or scow, there being switches S provided for placing any one or more of the motors in circuit. Although in Fig. 1 nfechanism has been shown for electrically operating motors it is to be understood that, if

Each of the preferred, other means may be utilized in lieu thereof.

Each pump which is used in connection with the system consists preferably of a casing 1 of approximately elliptical shape in vertical section, open at the bottom and having a depending flange 2 with which a cover plate 3 is detachably connected. Said cover plate and the lower part of the casing is encompassed by a strainer 4 having a flange 5 for the passage of securing members, such as machine screws 6, whereby the strainer is detachably connected with the casing.

' The upper part of the casing has a bearing 7 for the passage of a shaft'S carrying the pump head H. The latter may be described as consisting of two concavo-convex disks 9 and 10 connected together and spaced apart by a plurality of substantially radial wings 11, the hollow or concave sides of the disk being opposed to each other, and the edges of the disks, which taper in the direction of each other, being spaced suitably a circumferential outlet 12. The bottom disk 10 has an inlet 13 surrounded by a flange or collar 14, which is concentric with the axis of the shaft 8, and which has a bearing in the plate 3.

The casing 1 is larger than the pump head H both diametrically and axially which being filled with water when the pump is in operation serves in a measure as a reservoirto produce a steady outflow at the end of the delivery pipe. The casing has also an outlet which is disposed to one side of the shaft 8 and with which is connected an exit pipe 15 extending upwardly and terminating in a spout 16. The exit pipe is provided with brackets 17 affording additional bearings for the shaft 8. It will be found convenient to form the exit pipe with a lateral offset 18 to afford room for an electric motor M of ordiapart to provide nary construction, which is connected with 1 the shaft 8, and the casing of which, 19 may be connected with the pipe 15, so as to be supported by'the latter.

The shaft 8 and the exit pipe 15 may each be composed of a plurality of sections connected together by suitablejoints or coupliipgs, as 8' and 15, for convenience in han- If it shall not be desired to equip each barge with a pump, the wiring may still be maintained, and a pump may be carried from one barge to another and the motor may then be connected up, as will be readily understood.

The improved pump of the present invention is very simple in construction and effective in operation, Beingia submerged pump,

it will operate effectively to drain the water from the hold, and leaks will not interfere with the operativeness of the device.

Having thus described the invention, What is claimed is Z- v A pump comprising an inverted b0Wl-like casing) having an open bottom, a ca plate detac ably secured across the open ottom of the casing and having'a central orifice superposed fixedly disposed frusto-conica disks within and spaced throughout their extent from the wall of the casing, radial wings between and integral with the disks, the inner ends of said wings being cut away, there being a continuous annular outlet opening between the peripheral portions of the disks, a tubular casing u I ing a reduced en projecting into the orifice in the cap plate, sald extension bearing upon the cap plate, an outlet pips extending from the top of the casing, a sha journale'd thereon and secured to the up er disk, a removable pipe section upon t e first mentioned pipe, a shaft section journaled thereon and detachably engaging the first mentioned shaft section, and a motor mounted upon the removable pipe section for driving the shaft.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
