JOHN B. SPERRY, 0F AURORA, ILLINOIS, ASSIGNOR TO THE AMERICAN WELL WORKS,

y OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

PUMPING APPARATUS.

T o all whom it may concern:

Be it known thatI, JOHN B. SrERRY, a citizen of the United States, residmg at Aurora, in the county of Kane,.in the State of Illinois, have invented certain new and useful Improvements in Pumping Appfa;-

ratus', of which the following is a specification, reference being had to the accompanyf."

ing drawings. 1

This invention relates to .pumping appa'- important that the power be applied to the vertical shaft to the best advantage without y any'side draft upon the shaft itself.

It is one of the objects of this invention to provide a construction by which power may be transmitted to the shaft through a belt without there being any side draft on the shaft. .A

It is another object of my invention to provide improved means for the lubrication of such a construction.

It is another object of this invention to provide guide rollers for holding the driving belt in properposition relative to the shaft pulley, the guide rollers and the means for supporting the same being arranged in such a manner as to render the belt easily removable therefrom without unlacing. It is one of the objects of my invention to provide means insuring against the forcing of the water and sand upward along the pump shaft into the bearings for said shaft. This is accomplished, in the construction shown, by providing a packing between the water lifting elements and the bearing for the shaft immediately above them, by providing an opening from the shaft to the well casing above the packing and below` the bearings for lthe shaft, and by providing for a small head of Water sur rounding the shaft above said packing serving as'a water-seal. e

It is another object of my invention to provide-improved means for lubricating the bearings of the pump shaft by means of pure water supplied from any suitable source from the surface or by means 0f the water Specification. of LettersV Patent. Application led J' anuary 27, 191'3. VSerial No. 744,430.

being pumped, the same being thoroughly filtered or strained before being permitted to enter the' shaft casing.

It islanother object of this invention to improve apparatus of this description in sundry details hereinafter pointed out.

The means by which I have accomplished these objects are illustrated in the accompanying drawings and are hereinafter spel cificallyV described. That which I believe to be new and desire to cover by this applivcation is set forth in the claims.

r In the drawings, Figure 1 is a central vertical section through the upper portion of the pumping apparatus; Fig. 2 is Aa view of the upper end ofthe discharge head as seen y from the left in Fig. el, showing the `construction of thesupport for the guide rollers; Fig. 3 is an enlarged detail through one side` `of the drive pulley' mounted on the upper end of the pump' shaft; Fig. 4 isa central vertical section through the apparatus at the bottom of the well, showing the runners by which the water is lifted and showing' the bearing located just above the lifting devices. This figure also shows one of the intermediate bearings for the pump shaft; and Fig. 5 is an enlarged detail, being a central vertical section through the bearing immediately above the water raising elements.

Referring to the several .figures of the drawing, 10 indicates a base-plate fixed in lposition vu on a base 11. built about the upper end o the well casing 12.

13 indicates the discharge head, leading from one side of which there is a.l suitable dischargepipe 14. f

E 15 indicates the pump shaft mounted on the discharge head 13 by means of a roller bearing 16 of any suitable typejfV-AS shown in Fig. 1, the bearing 16, together with the flanges 17 upon which it is supported, completely-closes off a'portion of the discharge head 13 at itsupper end providing an oil y well 18.

19 indicates a discharge pi e, leading froml the bearing 16, being provi ed on its outer end with an oil-gage 20 and a stop-cock 21'.

yand 25 f the head 23.'.

for permitting the escape of any Vwater that may be forced upward through the stuilingorin any other suitable manner.

28 indicates an annular flange depending from the hub 27 of the pulley, being adapted to extend downward vbetween the flanges 24 29 indicates a roller bearing l tween the i-ange 25 of the head23l and the flange 28 of the pulley 26, said roller bearing comprising, as is best shown in Fig. 3, a'

hard steel cylinder 29 fxedly,- mounted-in ythe-flange 28, a. secondv hard-steel cylinder 291 fixed upon the flange 25, and a` plurality r.

of anti-friction rollers 29. Byreason 'of this construction, when the bearing 29` becomes worn,it can be removed and anewone substituted. As is'shown in,Fig. 1 the annular iangei25 is out of contactwith the shaft 15 so that when the belt, shown in dotted lines in Fig. 1 and indicated by the numeral 30,

is applied to the pulley the side draft is taken up byl the head 23 without in any way affecting the central position of the shaft 15. 31 indicates an oil tank connected by means of a pipe 32 to the oil well 33 formed by the,f1aI1ges`24'-,-25.` By this construction and arrangement the yoil well 33 is adapted to be kept fullof oil, thus insuring a perfect lubrication of the bearing-29, a circulation of the oil in the chamber through the bearing 29 being insured by the provision of openings 28a through the la'n'ge 28 near the upper end ofthe chamber 33. Oil is also adapted to flow over the upper end of the flange 25 into the oil well 18, thus keeping the bearing 16 flooded. with oil, aswill be readily underl stood.

34 indicates a bracket rising from one side of the head 23. l n

35 indicates flanged rollers Journaled 1n any suitable manner at the upper and the lower ends of said bracket 34. These rollers 35 serve to hold the belt 30 in itsproper position upon the pulley 126 with its center located approximately opposite the middle point of the bearing 29. When -it is desired to remove the belt 30 from the pulley 26 this canv be accomplished very readily without unlacing the belt when the belt has been removed from the drivewheel of the engine, aswill be readily understood.

As best shown in Fig. 1, the lower end of the discharge head 13 has secured to it a water discharge casing 36, which communiany approved type. vcasing 36- and the shaft casing 37 are also inserted beof Fig. 4. In this igll rom the water munication with the water discharge casing 36. l s As will be readily understood, the shaft 15 is adapted to be made in sections connected together by coupling sleeves 41 of The water discharge adapted-iv to be made in sections coupled together by the means shown at the upper endl l re 42-43 indicate flanges adapted to be screw-threaded upon the vlower and the upper ends, respectively,

' of' the abutting sections of the casing 36,

said sleeves being connected -together by bolts or by any other appropriate means. 44 indicates a sleeve having screw-threaded lconnection withthe adjoining ends of the.

sections-.ofthe casing 37, said sleeve 44 being supported by arms 45 carried by the'fianges 42-'43.` The sleeve 45 is provided with a bushing 46 composed of argota, vor other close grained Wood, or other suitable ma terial. In the lower end of Fig.' 1 the sleeve supported' by the arms 38 and supporting the bearing for'the shaft 15 is indicated by 47, and the bushing carried by said sleeve is indicated by the numeral 48.- As shown in Fig. 4, the lower end of the water discharge casing 36 has connected to it, by means vof bolts or in any other suitable manner, a pump bearing casing 49. Below this casing 49 are successively connected in series a pump shell 49, a second pump shell 49", and a bottom bearing head 50 which by means of webs 51 holds in position the bottom bearing 52 of the shaft. To the lower endof the bearing head 50 is attached the upper end'of the suction pipe 53.

The lifting elements of the pump are old and Well-known in the art. They comprise hubs 54 and 55 upon the shaft 15provided with runners 56 which rotate with the Shaft between the walls of the pump shells 49"-49" and the cone-shaped parts 57 which are supported by means of ribs 58 from the surrounding casings. Asbest shown in Fig'. 4, the hubs 54-'-55 are spaced upon the` shaft 15 byl means of a `plurality of bushings. A

bushing 15 has its upper end resting against Va shoulder formed in the shaft, against the lower end of which bushing thehub 54 is adapted to bear. A second bushingl" having its upper end'resting against the hub 54 serves to space the hub 55 away from the hub 54, and a third bushing 15,

which is'lsecured in position by means of ,lock nuts 15d which are screw-threaded upon ,the lower end of the shaft '15, serves to hold the parts snugly together. The three bushings and the two hubs 54-55 are caused to vrotate with the shaftv 15 by feathers -54aL and 55a, Yas will be readily understood. The bushings 15f-15"-15c are preferably formed of brass, thus serving not only to position the runners 56 upon the shaft but also providing bearing surfaces of extreme durability which will not readily corrode.

The .upper one of the v parts 57 is provided with'a packing-box'59 which is calculated to prevent theforcing of any water and sand upward along the shaft into thebearing at the lower end of the water discharge casing 3 6. In order that any water and sand whichf might be forced upward through the packing-box 59 may be prevented from being forced into .the bearing just above it, lan opening 60 is provided about the shaft 15 communicating with the well casing outside of thewater discharge casing by means .of diagonally positioned dischargeports 61. v

a indicates al flexible washer surrounding the shaft 15 above the'packing box 59 and fitted tightly to the bushing 158. 'Ihis washer serves to prevent air from entering' the pump casing from the well through the ports 61, and also assists in' preventing sand from being forced upward along the shaft outof the pump casing intothe bearing above, being very elicient on account ofits tight fit upon the bushing y15". The shaft casing 37 also ends and is connected to the pump bearing casing 49 at the'same point as that at which the casing 36 vis connected, the lower end of said casing 37 inthe. construction shown, being screw-threaded upon u' a sleeve'62 forming part` ofthe bearing cas-v ing 49. Said sleeve -62 is provided'with a bushing 6 3, composed of argota or other suitable material, lforming at bearing .for the shaft 15. f. f

Referring again to Fig. 1, 64 indicatesa l pipe leading` into ,the chamber 65 between the flange 39 and the stuing box 22 in the discharge head 13.I Said pipe 64 is provided at its upper lend ywith a funnel 66 whereby water can bepoured into said ychamber 65,

as will be hereinafter `described,rsuch water being adapted to How 4over the upper. en d of the casing 37 into'the interior thereof.;

The sleeve 47 is twoy cone-shapedv ward the 'full length of the casing 37. 'Thei sleeve 62 at the bottom of the casing 37 is providedwith a duct 70 passing vertically.` through the sleeve, opening at its lower end into the opening 60, which is thus kept filled with Water| duringthe operationr .of lthe pump up 'to the level determined by .the I lower edge of the upper end of the discharge ports 61, thus providing' a permanent water seal as abovev described. The .sleeve 62 is.y

also pr'ovided with a duct 714 leading partiallyI through said sleeve 62, connected at l its lower end by means of a short section of pipe 72 and a suitable duc'tthroughv a portion of the bearing-casing 49 withy apipe 73, j

which extends downward within the wellcasing 12, pa'stthe water-lifting elements to the'lower bearing 52. The lower Ibearing 52 is provided with a`cap 52a screwthreaded upon its lower end, vaslbestshown .in'Fig 4. j
