Application tiled February 11, 191.3.

To all fw/zom 'it may concern Be it knoivn that l, Cruonou L. HOWELL, a citizen of the United States of America, residing at Munger, in the county of Bay and .State of Michigan, have invented certain new and useful Improvements in R0- tary Pumps, of ivhich the folloiving is a specification, reference being had therein to the accompanying drawings.

rllhe invention relates to rotary pumps more particularlyT designed for use in irrigation, and it is the object o-f the invention to obtain a construction Which is efficient, may be. constructed at small cost, and requires little repair.

To this end the invention consists in the construction as hereinafter set forth.

ln the drawings: Figure l is a side elevation of the Wheel. Fig. 2 is an elevation at right angles to Fig. l. Fig. 3 is a cross section through the periphery of the Wheel showing the bucket construction.

A is a rotating shaft; B are spokes connecting the hub C with the rim D; E are buckets secured to the rim D and which are open at one side; and F is a segmental plate which extends around a portion of the rim D and forms a cover plate for the open sides of the buckets. This plate is preferably provided with flanges Gr and H for overlapping the outer and inner Walls of the buckets, the outer flange Gr being of greater depth than the inner flange H. The Wheel is preferably mounted in an inclined position as shown in Fig. 2 and the plate F is arranged adjacent to the down-turned side and extends from the. bottom to near the top of the Wheel.

l is a chute or trough, Which is adjacent to the upper end of the plate F and is arranged to receive the Water discharged from the buckets.

ln operation, motion is communicated to the shaft A from any suitable source of poiver and the Wheel is driven in the dircction of the arroiv. The lovver portion of the ivheel, as for instance below the line J K, is beneath the surface of the loiver ivater level, and consequently the buckets E will be filled with liquid before passing into proximity to the plate F. As the Wheel rotates these buckets will be carried around the plate F, which latter will retain the greater portion of the Water therein, particularly Where the Wheel is rotated at a relatively high velocity. The overlapping flanges G and H, While out Specification of Letters Patent.

l of contact with the buckets, are nevertheless sufficiently near to form a Water packing which will reduce the leakage to a small amount. As soon as the buckets pass beyond the upper end of the plate F they are free to discharge their contents laterally on to the chute l. and by reason of the inclined position of the Wheel the Water is rapidly discharged, so that the buckets are completely emptied before passing beyond the chute I.

The construction just described is one capable of being operated at relatively high speed and the centrifugal force Will therefore lessen the tendency to leakage around the inner flange H. On the other hand, there Will be an increased pressure of Water at the joint between the outer flange Gr and the buckets, I therefore constructed the outer lflange Gr of greater Width than the inner flange, as shown in Fig. 3.

that I claim as my invention is:

l. A rotary pump, comprising a rotating wheel, a series of relatively stationary buckets carried by the periphery of said Wheel and provided with an open side for discharging laterally or sideWise in relation to said ivheel, a stationary segmental plate extending around a portion of the periphery of the wheel adjacent to said buckets and closing the open side thereof.

2. A rotary pump, comprising a rotating ivheel, a. series of relatively stationary buckets carried by said Wheel having open sides for lateral discharge, a segmental stationary plate extending about a portion of said ivheel adjacent to said buckets and closing the open sides thereof, and a flange at the edge of said plate overlapping the peripheral side of said buckets and forming a Water packing.

3. A rotary pump, comprising a Wheel revoluble about an inclined axis, a series of relatively stationary buckets carried by the peripheral portion of said Wheel, said buckets having open sides for lateral discharge, a stationary segmental plate extending around a portion of said Wheel adjacent t0 said buckets and closing the open sides thereof. flanges extending from opposite sides of said plate overlapping said buckets and forming a water packing, and a trough or discharge chute at the upper termination of said plate for receiving the Water laterally discharged from said buckets.

A rotary pump comprising a Wheel, a series of buckets attached to the rim of said Wheel and having open sides for lateral discharge, each of said buckets having peripheral segmental inner and outer Walls connected by a return bend, a stationary segmental plate extending around a portion of said wheel adjacent to said buckets and closing the open sides thereof, flanges at opposite edges of said plates overlapping said buckets and forming a Water packing, and a trough 10 or discharge chute at the termination of the upper end of said plate for receiving the Water successively discharged from said buckets.

In testimony whereof I affix my signature in presence of tivo witnesses.
