PUMP.

To all whom t may concern.'

Be it known that I, FRED I. GETTY, a cit-izenof the United States, residing at Jenw nings, in the parish of Calcasieu and vState of'Louisiana, have inigmt'ed certain new and useful Improvements in Pumps, of which the following is a specification. This invention relates to improvements in centrifugal pumps, and more particularly to' those generally known as deep well pumps. 'l

f. The object of lthe invention is to provider a pump ofthe class stated which is adapted to eiiciently deliver water, in large or small volume, and capable of operating in ya comparatively small space, and with a compara- .tively small expenditure of power for propelling-git.

A further object of this invention is to provide a pump, -whi'clli i's adapted to operate, and which can be conveniently installed at any desired depth, and which operates equally well whether' the water level in the ground be high or low.

The invention also aims to provide a centrifugal pump construction which so impels and guides the water, that it continues iii the same general direction given it.by the iinpeller, along curved lines of large diameter, thereby `greatly reducing to a minimum the rictional resistance incurred by the water in its passage through the pit.

rlhe invention also 'comprehends improve- .ments in the specitic details of construction and arrangements of parts, which will be hereinafter and more fully pointed out in ythe claims. v

In the drawings: Figure 1 is a view partially in section, and partially in elevation of the upper portion of my improved pump. Fig. r is a View similar to Fig. 1, but illustrating the lower portion of the pump structure. Fig. 3 is a vertical section on the line 3--3 of Fig. 4, illustratingr ou an enlarged scale the pump structure. Fig. 4 is a horizontal section on the line 4-4, Fig. 3.

Sections as may be found desirable, the sections being coupled together by the usual couplin s, 2. Near the bottom of the tube 1, isa s rainer 3, of any approved pattern.

The-upper end o the tube is threaded, to

engage athreaded hollow cap 4, the upper port-ion o f which 1s reduced, and is provided on its outer surface with two beveled spaced apart camf lugs 5, and below the same 1s a beveled flange 6. The cap supports the pit 7, the latter comprising a base 8, recevi ing chamber 9,'and a dome 16. The base is `igirovided with a neck, the lower edge of which is beveled as at 11 to coperate with tihebeveled iange 6, and is further rovided..

with internal spacedapart cam ugs 11,

which cooperate with the spaced lugs. 5,. The cam lugs 5 and 11,- form a means for' locking the pit to the cap," the 'cam surfaces at 13. The upper inner surface of the ver-- tical portion of the base inclines upwardly from the inner edge, and is concave as shown at 14, for a purpose to be described.

The walls of the body portion 9 of the pit are vertical above the concave surface of the base to form an uninterrupted passage for the water when introduced to the pit by the impeller, and is somewhat reduced in diameter above the impeller. upper end of the reduced portion is a ring 15, to which is bolted a dome 16, the upper end being flanged and formed with an opening 17, and below the {iange is an outlet opening 18, in which tits a discharge pipe 18a. The discharge pipe inclines upwardly which permits of the pump being set low, to accommodate Ybelting, and to deliver to an elevated flume. A, pump head 10 fits in the opening 17, and has a flange 19, which is bolted to the flange of the dome'. The

1. An opening Qt'extends entirely throufrli' the head to accommodate an impeller shat.

ArFheliead is formed l'with a water receiving At the chamber 21, which communicates with thedome by means of an opening 22. An overfiowpipe 23 extends upwardly within the water chamber, and it communicates with an outlet pipe E24, tapped in the flange 1S). Above the water chamber 20, is an oil chamber 25, supplied with lubricating oil by means of 'a pipe 26, connected to an oil` coupling 33, by means of which another sec-v tion 34 is attached. The column is made up of these sections, the lower one 35, terminating in. a cap plate 36. The cap plate is bolted to a ring 37, having a plurality of grooves-38, formed on its under side to receive a series of spaced vertical tangentially arranged curved vanes, 39. The lower edges of the vanes fit in grooves 40, formed in the lupper edge of a cup shape bottom member 41. The member 41, is reduced at its lower end to-fit Within the hollow cap 4, and is internally threaded to receive a short section of pipe 42. Just above and outside of the lower reduced end of the cup member 41, is a groove 43, to receive packing'rings 44, against which the upper end of the hollow cap abuts to form a water tight joint.

The upper and lower cndsof thc vertically disposed curved vanes are riveted indicated at 45, to the ring 37, and the cup shape member 41, respectively. By this construction, the ring vanes, and cup member, form a cage, to receive the impeller as clearly shown in Fig.' 3..

The impeller shaft 46,'-is mounted in theI pump head '10,and the tubular column 3l, and extends below the same, and has attached thereto adisk 47, from the under side of the center of which depends a cone 48. Secured to the under side of the disk 47 is a series of impellers 49. Each impeller is pointed at its ends, and is curved to throw the water outwardly toward the curved vanes. The inner ends of the impellcrs terminate at theouter edge of the cone 48, while the outer ends terminate at the edge of the disk 47 andin proximity to the vanes. The inpellers are arranged withrelation to each other so thatv the intake space formed between them is narrower than the outlet at the circumference of the disk 47 whereby the water is prevented from choking.

To the underside of the impellers is fastened a disk 50, formed with a centrally disposed, depending, tubular, hollow extension 51. The extension 5l is in alinement with the opening 41a, in the cup shape member 41, and its edge 1s normally slightly spaced from the upper surface of the latter, as indicated at 52, to permit of a slight'adjustment of the impeller' that it may be properly positioned with reference to the vanes.

The tubular column 31 is provided at suitable intervals u'ith bearings 53, for the shaft 46, and in order to brace the column as much as possible and to fill the space between the shaft and the casing the spaces between these bearings and the column are provided with wooden filling blocks 54. These blocks serve to stiften the column, and at the same `time assist in retaining the shaft in alinement. The opening in the lowermost sectionof the vertical column 31 is reduced and a bushing 56, is placed therein to form a substantial bearing for the shaft just above the impeller.

T here are three collars placed on the shaft 46 in the oil well 25, the lower one 57 being supported on a bushing 58, mounted in the pump head 10. The intermediate ring 59, is formed with a plurality of openings 60, for the reception of balls 61, which have a bearing on the lower ring whilethe upper ring 62, engages the upper surface of said balls. A pulley 63, is secured to the upper end of the shaft 46 and its hub is supported on the upper ring 62. The pulley is hollow and tits over the pump head as'shown in Fig. 1.

In operation, the tube and the pit are sunk into the ground to a depth sufficient to insure a supply of water, and the parts are assembled, as described. When power'is applied to `the pulley 63, the impeller is revolved within its surrounding cage and throws the water out by centrifugal force against the concave surface 14, and the vertical walls of the receiving chamberi); When the water is driven out by the impeller it passes through the spaces formed between the vanes at a high rate of speed, striking the concave surface of the pit at a very oblique angle, then continuing, without change of direc tion, on a spiral course upward. In its up ward spiral course the speed of theivater-'is gradually reduced, and is transformed into pressure.

From practical experiments I find that the pressure of the water resulting from the relai tive location of the vanes with reference to the impeller, cannot b e successfully utilized to the best advantage, unless the walls of `the pit are so'arranged to permit of the cotumn of water to continue to flow upward in a spiral course, in anv uninterrupted passage. To meetthiscontingency the inner surface of the pit is. vertical 'adjacent the vanes, and furthermore the upper inclined surface of the base 8 is concave. As the water is forced out through'the spaces between the vanes it contacts with the concave sur-face 14 and the Vertical wall of the pit and is thereby spirally lifted in a solid column in the pit. This spiral 'action of the water in the pit relieves the pressure on the water in currents of inseam the caga, and thereby' does not retard the lifting action of the hupelleix Ot course. after the column of water is elevated some distance in the pit, the spiral action is gradually decreased and the water rises by the pressure below until the outlet opening is reached,

It will be observed that the passages; hev tween the valles are so arranged that` the Water are unobstructed and therefore 'follow their natural course, That is to say the walls of the passages do not change the direction nor impede the velocity .of the natural How of the water when thrown out from the center of the pump. but allows same to 'low :n unimpedcd tangential streams out of the cage and into thc casing. i

l find that constructing the impeller and the vanesfaind pit surfaces in the manner set forth, that the water is ctl'cctually lifted Whether the well be deep or shallow. l also find that au increase in the speed of the inipellcr is followed by au increase in the volume ot' water pumped, which a Jltrided advantage. The dispewtion of the tam-s, with relation to the pit allows the two passage of the water, and prevents its return to the periphery of the impeller.

The iiupellcr is wholly sul'iported at the upperend et the pit; so to"y permit of a itil'ctv of adjustnunt in the cago with ret'- erenceto the vanos, whereby to secure the best possible results.

The bearing iu the pump head receives mnsidcrable friction, duc to the tact that the impeller is si'ip'ported thereby. There-- tore, l find it quito essential that iiirovision be made for coolingr the bearing. and it is for this reason l arrange the water jacket. la the water riser-i in the pit, a small supply "wills ypass up through thc openings 2i?, and into the chamber 2L and overtlow through the pipe 23; This constant Ie'irculntion ot' tho 'water hos-ps ilul head :ind the bearing sutliciclztlv cool to prownt destruction of the parts by frictionV ll' olv-vatiluf the discharge cud ot the ltl i! assista in starting` tho water to dilate in the bearing in the pump head. Vlf au elevated discharge pipe is not elnpioyod, the unter may be started through thv chamber by temporarily covering the thc pipe, which causes it to back up, an' `titer the cover is removed and the water enters the chamber it will continui to flow .e a long as the pump runs, as the ciw-apc pipo lit, acts as a siphon.v
