The has@ farmed iks water away from the entrance to the space 54, and into the volume ot water being radially thrown out between the spaces of the vanos i2?) Buti while this is effective to a degree. there will be a small amount of water pass into the space 5ft, and in order that it ma)v drainfinto the spaces formed betwetn the bladesdof the impeller, and form a part lof the volume of water thrown out, l provide in the plate 50, a series of openings 58, so that in ase the space 54, should become tilled with water, pressure will be relieved by water flowingr through the openings im, as will be readily understood. The vacuum created by the revolving of the impeller tends to draw the water from the space 5-1, through the openings 5S, so that I etliectually relieve the undue pressure-between the impeller and the casing and there hy prolong the lit'e of the bearings in the head of the pit. y

On the periphery of the lower platel is formed a series of projections or ribs 59, which incline in the direction of the rotation ot the impcllenand the reverse of tht` inclination oli' the blades or ribs 56, on the plate, 5u. The same action takes place in reference to these ribs as that of the ribs fit1, so that the rihs), will etfectually tend to litt the 'water which would ordinarily pass ii'ito the ,spare 51.*?. below the iinpeller t 'torce it baci: into the volume of water -f out through the vanes 23. As has beer wl in reference to the water passing into the space 54, it is impossible to prevent Home ot the water from passing into the space 51"; but a large proportion of what would pass is directed through the openings between the Yanes. so much that undue pressure on the impeller is avoided, and the small Supply entering the space will he drawn into the impeller through the space til, formed between the depending flange 25) 'and the hasefQet. I

ln practice it. may be desirable to omit the vanes 59 on the periphery of the lower flange 51, in order to create a pressure in the space 5l with water and thereby counteract or balance the downward thrust of the iml peller,

In operation. power is applied to the pulley at the upper end ot' the pump shaft and the iiupeller is rotated in the direction ot thtl arrow shown in Fig'. i2. The blades of the inipeller create a vacuum in the usual manner and draw the water upwardly from the well tubing Si, and throw it out in the direction of the rotation ol the impeller in the course it would assume when centrifugally thrown by the` blades of the impeller through the openings between the vanes 23. The water is permitted to flow from the vanes 23. in tangential steams into the passage formed het weert the vanes and the walls or'. the pit, winch tends to elevate it in a -r0 tary and spiral manner from the bottom to the top of the pit. as clearly set forth in my prior application. the impeller revolves, the vanos or projections` 5o and 5E), act on the watei 'hieh tends` to pass ul'iw'ardly and downwardly from the impeller` and causes the same lto be directed into the volume of water thrown outwardly by the blades. The

water which passes the vanes 5G, and finds its way into thc space 54, will be drawn through the openings 58. and will be forced outwardly from thc impcllcr with tlc greater volume of water passing therefrom. The water which passes into the space 51a, will be drawn into the main volume of water through the slight space G1, as previously described. Hence the pressure which may remain against the walls of the impeller by the small amount of water which will pass the vanes 5G and 5t), will about equalize the pressure, consequently no undue strain downwardly on the impeller will occur and the bearings ot the shaft in 'the head of the pit will not be destroyed, as would otherwise occur. 'hen thc' shaft 30, is revolved the balls 3Q and the disk associated therewith forming part of the bearing,f will also revolve and agitate'the oil in the chamber l2. The rotary motion imparted to the oil by the moving parts is broken by the ribs or battles 83, which causes the oil t0 maintain its level in the oil chamber and insures the shaft be- 'ing` thoroughly and continually1 lubricated by a sutticicnt quantity of oil in contact therewith as long as the said oil is being fed to the pump.

The arrangement of the lagging in the casing' and the bearings therein is of the utmost importance in a pump structure of this cl'iaracter, inasmuch each section of the casingr is a unit in itself, and ath-:rds great convenience in assembling the pump or when removing the various sections forming the casing for repairs, etc.

'hen the bottom ot the casing is seated on the flange t3, of the base of the pit, it forms an etlect'ive water-tight joint so that the water which will naturally tlow to the bottom of the base will not leak through into the well tubing, nor will air be permitted to pass through to destroy the action of the impeller when sucking` the water from the well tubing. lt may also be stated at this point` that by the construction of the slot 25, the packing 2G. is held rigidly in position and cannot become displaced.

In assembling,r the pump, or when ctliecting. repairs it frequently occurs that foreign substance or parts of the' mechanism will be dropped into the pit, but by reason of the form of the bottom ot' the pit 2 such accidents will not obstruct the operation of the parts or prevent 'the proper seating of the hase 24, on the tlange 6, owing to the space beneath the operating parts.
