* Application filed January 6, 1927. Serial No. 159,398,

tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. Inthe accompanying drawings v Figure 1 shows in vertical section, a device constructed in accordance with the in- Figure 2 is a'transverse section; Flgure 3 1s a top planwherem parts are The device forming the subject matter of this application is a centrifugal pump, including a casing or stator. .The casing o'r stator comprises a funnel-shape body 1 having a thickened base 12, into which is threaded a collar 6 having a flange 7 overlapping the upper'surface of the base 12, the

collar 6 carrying a spider 2 including a hub 8. The numeral 3 marks, a bearing pin of hardened steel, the upper end of which is of tapered form. The bearing pin 3 base reduced lower end'9 which is threaded into the hub 8 of the spider2, a shoulder 10 on the pin cooperating with the 'hub. 8 of the s ider to limit the downwardmovement of t e pin 3 when the end 9 thereof is threaded into thehub 8. An annular foot piece. 11 forms theintake forthe casing of the pump and is held against 'the lower end ofthe base 12 by securing elements 14.

A cap 15 constitutes part of the casing, and is mounted upon the bod 1, theca Y15 and the body 1 being shoul ered toget er,

as at 16, to prevent relative laterahmove ment between the parts 5 ecified. The cap 15 is held on the body 1 y securing members 17. The outlet forthe body 1 is marked by the numeral 18 and is in the form of yolute, formed integrally .with the cap 15,

and upstanding therefrom to minimize space, considered horizontally. The outlet 18. communicates with the interior of the I casing by way of a reduced throat 19, and,

the liquid, having traversedthe outlet 18,

flows away through an opening 18 into a nipple 20 formed integrally with the cap 15.

The cap 15 includes an upstanding tubm l-ar pedestal 21 surmounted by a gland 22,

there being a bushing 23 in the pedestal 21,

at a point near to the gland 22, the bushing being preferably made of bronze.

Having-thus described the casing or stator, th e constructionof the rotor will now betakenup.-' f

A shaft 24 is journaled in the gland. '22

and in the bushing 23 and has an axial'passage 25 for the delivery of oil. The shaft 24 extends into the neck 26 of a rotor, the.

rotor including abody 27. The body 27 of the rotor is disposed betwee'n'the cap 15 and' the'body 1, the neck 26 of the rotor being. located in the enlarged lower part of the hardened steel, is seated in a recess 4 in the n'eck'26 ofthe rotor, the thrust bearing being shaped, as at 28 to receive the conical end 30 of the bearing pin 3. A key 29 holds the shaft 24, the thrust bearing 4 and the rotor togetherfor simultaneous rotation, the key 29 being engaged with the neck'26 of the pedestal 21. A thrust bearing 4, made of a rotor.,. The thrust bearing 4' has an on port 38. This port communicates with the lower end of the oil. passage 25 in the shaft 24.

Oil introduced into the passage 25 will find its way, by means of the-port.38, on the conical end 30 ofthe bearing pin 3. The

entire rotor is supported to'turn on the conical'end 30 of thebearing pin 4 and this part,

it is to'beobserved, can be adequately lubri- 'cated, owin to the construction shown at 2538. A ushing 31, generally of bronze, is located in the neck 26 of the rotor, about the bearing pin 3, and abuts against an in- 27 of'the rotor has a central chamber 39. which receives the spider 2 and its hub 8. Passages 34, of.whichthere maybe any desired number, lead from the chamber 39 ternal shoulder 33 in the neck 26. The body to the peripheryof the body 27 of the rotor. I

In practical operation, when the rotor is turned by means of the shaft 24, the liquid rises through the intake member 11 and moves upwardly through the spider 2, the' liquid traversing the passages 34 of the .rotor and moving upwardlynto the outlet member 13, by way of the throat 19, the liquid leaving through the opening 18 and the nipple 20.

A ring is located in a superficial annular recess 37 formed in the lower edge of the body 27 of the rotor, and the ring can play freely up and down, the ring having lugs 36 that are received in recesses -36 in the lower part of the body 27 of the rotor. As shown at 36, the ring 35 has a taper in cross section, so that anything that may happen to-getbeh-ind the ring can work down and out. The ring bears ou'another ring 40 which is seated in an annular groove 40 formed in the base 12 of the stator. When the rotor is in operation it forces liquid under pressure on top of the ring 35, and the ring is pressed down on the ring 40 so that there is no leak across the extreme lower end of the body 27 of the rotor. v

The bearing pin 3 is located entirely with- 1 in the rotor, and the parts 6-7.-8, which support the bearing pin, are located entirely within the stator orcasing. In this respect, the pump shown is different from pumps of that sort wherein the shaft-that carries the rotor isjournaled in a thrust'bearing disposed outside' of the casing. Such pumps are hard to oil, and to maintain against the action of grit, Whereas my pump is not.

What is claimed is o 1. A pump comprising a stator having an inlet and an outlet, a rotor having a central chamber communicating with the inlet, the rotor being provided with laterally extended passages communicating with the chamber and discharging into the outlet, a substantially vertical bearing pin, means carried by the stator and located in the chamber for supporting the bearing pin, a shaft secured to the rotor, a thrust bearing seated in the rotor and interposed between the lower end of the shaft and the upper end of the bearing pin, the bearing pin and the thrust bearing carrying the weight of the rotor, and means for lubricating the bearing pin through the shaft and the thrust bear- 2. A pump comprising a stator having an inlet and an outlet, a substantially horizontal rotor having a central chamber com- Inunieating with the inlet, the rotor being provided with laterally extended passages connnunicating with the chamber and discharging into the outlet, a substantially vertical bearing pin, means carried by the stator and located in the chamber for supporting the bearing pin, and mechanism for supporting the rotor on the upper end of the beartudinally of the bearing, and means mounted on the stator, and housed completely within the stator, for supporting thebearing.

In testimony that I claim the foregoing as-iny own, I have hereto aflixed my signature.
