United States Patent 11 Claims. (Cl. 103-103 The present invention generally relates to a pump construction and more particularly to a pump which has a basic unit which may be employed in conjunction with a priming tank as a pump for irrigation purposes such as for pumping water from ponds, creeks, irrigation ditches and other shallow bodies of water so that the water may be distributed through sprinklers, irrigation troughs or the like for placing the water on the soil so that it will increase the productivity thereof. The pump may also be employed for use in a well of any type for pumping water therefrom and discharging the same with the pump unit adapted to be arranged in multiples if desired and adapted to be used in small casing type wells or relatively large bore wells.

The primary object of the present invention is to provide a combined deep well and portable pump incorporating both the features of a centrifugal pump and an axial flow pump in that the centrifugal motion imparted to the material being pumped is partially converted into axial force by a spiral deflector arrangement which remains stationary which cooperates with an enclosing casing for guiding the flow of discharge from the centrifugal impeller.

Another object of the present invention is to provide a pump in accordance with the preceeding objects in which the various bearings appearing therein are lubricated by the water being pumped with a filter arrangement being provided in each bearing or bushing so that any sand or other foreign material entrained in the water being pumped will not flow into the area between the operating shaft and the bushing thus preventing this type of damage and providing a long wearing and well lubricated arrangement.

A further object of the present invention is to provide a pump in accordance with the immediately preceding object in which seal means is provided in each end of the bushing with the seal means being in the form of an O-ring which is forced outwardly into sealing engagement when the pump is actually pumping water.

Yet another important feature of the present invention is the provision-of a pump having a construction which permits it to be used in conjunction with a portable priming tank which may be driven from the power take-off of a towing tractor whereby the pump may be backed up to shallow water and the movable intake therefor dropped into the water so that the device will be readily adaptable for this particular use.

Yet another feature of the present invention is to provide a pump which also is adapted for insertion into a well pipe casing of slightly larger size with the pump being provided with seal means for sealing engagement with the casing whereby the area above the pump will be used as a flow pipe.

Still another feature of the invention is the provision of an adapter at the upper end of the pump assembly for attachment to a flow pipe whereby the pump assembly may be self-contained and lowered into a large bore well whereby the flow pipe will support the pump and provide the discharge therefor.

Other objects of the present invention will reside in its extreme simplicity of construction, adaptation for its ice particular uses and its relatively inexpensive manufacturing and maintenance cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 9 is an exploded group perspective view of the basic elements of the pump unit; and

FIGURE 10 is a side elevational view illustrating the self-contained unit of the present invention which is inserted into a well with the fiow pipe being attached directly to the pump unit.

While the invention will be described throughout as being adapted for pumping water for irrigation purposes, it is pointed out that water may be pumped with this pump for any purpose desired and it is also pointed out that the pump may be employed with any type of liquid desired to be lifted or otherwise moved and is adapted for other uses for which pumps are normally employed. The various materials from which the pump is constructed are optional with the materials being those satisfying the requirements of sound engineering principles. Also, the various sizes and size relationships may vary without departing from the scope of the present invention.

Referring now specifically to FIGURE 3 of the drawings, the numeral 10 generally designates the basic pump unit of the present invention which includes a cylindrical pump barrel or casing 12 having an internal bore 14 of constant cross-sectional area extending between end shoulders 16 and 18 and internally threaded portions 20 disposed outwardly of the shoulders 16 and 18 respectively.

Disposed adjacent the outer or lower end of the barrel 12 is an annular collar 22 having a peripheral outwardly extending flange 24 disposed in abutting engagement with the shoulder 18. The flange 24 is held in captive relation against the shoulder 18 by a threaded adapter 26 having an internally threaded portion 28 engaged with the screw threads 20 whereby removal or" the adapter 26 will permit removal of the annular member 22. The inner surface of the annular member 22 is provided with a lower inclined surface 39 and an upwardly inclined surface 32 joined by substantially cylindrical bore 34 which forms a water inlet for the pump barrel 12.

Disposed inwardly or above the annular member 22 is a sleeve-like member 36 having a peripheral flange 38 resting against the shoulder 16 with the flange 38 being held against the shoulder 16 by an adapter 40 having an externally threaded portion 42 for registry with the internal threaded portion of the barrel 12 outwardly of the shoulder 16. The lower or outer portion of the sleevelike casing 36 is tapered as indicated by the numeral 44 with the largest diameter being disposed adjacent the annular member 22. The inner end of the sleeve-like member 36 is provided with an outwardly inclined surface indicated by the numeral 46 which is substantially identical to the inclined surface 32 on the. annular member 22.

Disposed within the sleeve-like casing 14 is a deflector 48 that is tapered complementary to the taper of the internal surface, 44 of the sleeve-like member 36 with the outer surface of the deflector having a plurality of radially extending longitudinal vanes or blades 50 integral therewith with the vanes or blades 50 being spiraled longitudinally thus forming a deflector for water in a manner described hereinafter. The outer edge of each of the blades 50 is provided with a shoulder 52 adjacent the lower end thereof for engagement with the outer end of the sleeve-like casing 36 as shown in FIGURE 3 for limiting the insertion of the deflector 48 into the casing 36 thus preventing binding between the two elements and permitting removal of the deflector 48. Thus, in operation, the deflector 48 becomes rigid with the sleeve casing 36.

The deflector 48 is provided with a longitudinal bore 54 extending therethrough with the bore 54 having a bushing or bearing element 56 disposed therein for journaling an elongated operating or power shaft 58 with the shaft 58 extending beyond both ends of the deflector 48.

The deflector 48 is provided with a plurality of radially extending apertures. 66.. therein which communicate with an annular recess 62 in the inner surface of the bore 54 and disposed between the deflector 48 and the bushing 56. The bushing 56. is also provided with a plurality of radial apertures 64 communicating the recess 62 with the interior of the bushing 56 for admitting water into the interior of the bushing 56 for lubricating and cooling the bushing 56 during rotation of the shaft 58. Disposed within the recess 62 is a continuous cylindrical member of felt 66 which acts as a strainer for the hibricating water thus straining out any sand or other foreign materials which may be entrained in the water.

Disposed at each end of the bushing or hearing 56 is a sealing collar '70 and 72 respectively with the

collars

70 and 72 having a peripheral recess 74 extending longitudinally thereof which receives the inner portion of an an O-ring 76 which has the outer portion thereof anchored to the bore 54 by virtue of a peripheral groove in the bore 54. The lower or outermost seal 70 is provided with a flat headed portion 78 while the otherv seal 72 is provided with a conical-shaped head as indicated by the numeral 80 having an O-ring seal 82 therein in engagement with the surface of the shaft 58 thus sealing the shaft 58 in relation to the member 72 with the O- ring 76 securing the member 72 to the deflector 48 in sealed relation thus providing an effective seal for holding the lubricating liquid within the support hearing or bushing 56 for the shaft 58.

Mounted on the shaft 58 immediately outwardly of th deflector 44 is a centrifugal type impeller 82 secured thereto by a setscrew 84 with the impeller having an outer ring 86 interconnected with the main body by a plurality of blades 88 which generally extend radially between the body and the outer member 86 which is disposed in inclined relation complementary to the surface 32 on the annular member 22 with the outer ring 86 having a projecting cylindrical collar 9-0 received within the cylindrical portion 34 of the annular member 22 thus forming a guide for rotation of the impeller 82 so that water taken into the cylindrical member 90 will be engaged by the impeller 88 in such a manner that the water will be pumped through the impeller 82 into the deflector 48. The blades 88 may be curved slightly spirally or in any manner whatsoever for increasing the effectiveness of the impeller.

Disposed at the upper end of the sleeve casing 36 is a second impeller 92 identical in construction to the impeller 82 and being secured to the shaft 58 by virtue of a setscrew 94. The impeller 92 is related to the upper end of the sleeve casing 36 in the same manner as the impeller 82 is related to the annular member 22. It is noted that the lower end of the adapter 26 may be externally threaded as indicated by the numeral 96 for engagement with the internal threads 98 on the adapter 40 so that a multiplicity of the pump units 10 may be disposed one above the other or the pump units may be disposed in spaced relation by suitable pipe-type connection.

Referring now specifically to FIGURES 1-3, it is noted that the adapter 40 has a generally cylindrical fitting 100 screw threadedly attached thereto with the fitting 100 having an externally threaded end 102 and an ex ternally threaded end 104 in engagement with the threads 98 in the adapter 40. Also, the fitting 100 is provided with an annular flange 106 which in this instance is employed to retain the inner edge of a collar 108 clamped between itself and the outer end of the adapter 40.

In the installation in FIGURES 1-3, the pump unit 10 is inserted into a primer tank 110 having an end wall 112 with an opening 114 for receiving a portion of the adapter 40 as well as having the outer surface thereof countersunk for receiving the flange 108. Disposed outwardly of the end wall 112 is a cylindrical housing 116 having a flange 118 disposed against the flange 108 with the flanges 118 and 108 being held in abutting sealed relation by an attaching flange 120 secured to the end wall 112 by suitable fastening bolts 122 with a gasket 124 being interposed therebetween for adequately sealing the pump unit to the priming tank. The cylindrical housing 116 is provided with a radially extending discharge pipe 126 which may be connected to suitable discharge conduits 128. A transverse closure plate 130 is provided in the housing for scaling 011 the water pumping area and this plate 130 is provided with a support sleeve 132 having radial apertures 134, a felt filter 136 inwardly thereof and disposed in a recess together with a bushing 138 having apertures 140 for communicating the interior surface of the bushing 138 with water for lubricating the shaft 58. A packing nut 142 is provided in the outer end of the sleeve 132 with suitable packing material 144 disposed inwardly thereof for compression by the nut 142 for sealing engagement with the shaft 58. The cylindrical housing 116 outwardly of the transverse plate 130 is provided with diametrically opposed enlarged openings 146 for providing access to the packing nut 142 and the outer end of the housing 116 is provided with a transverse plate 148 having a support sleeve 150 therein together with hearing elements of the thrust type which are generally designated by the numeral 152 and which may be of any suitable construction.

The tank 110 is provided with an inlet adapter 154 having a tangentially extending fitting 156 together with a rearwardly extending inlet pipe 158 which may be provided with any suitable strainer or similar mechanism for straining out enlarged foreign objects from the Water being pumped. The connection between the member 156 and the adapter 154 is of the swivel type such as would be provided by employing a pair of O-rings therebetween to permit raising and lowering of the inlet pipe 158 in substantially a vertical plane. Any suitable mechanism may be provided for raising and holding the pipe 158 in a vertical elevated position.

The tank 110 is mounted on a portable framework 160 have ground engaging wheels 162 and a forwardly extending tongue 164 which may be connected to a drawbar of a towing tractor which is generally designated by the numeral 166. Also, the outer end of the shaft 58 may be provided with a universal coupling 168 for connection with a telescopic drive shaft 170 which may be connected through a universal joint 172 to the power take-off shaft 174 of the tractor 166 for driving the pump unit 10 in this particular case.

Referring now specifically to FIGURE 5, it is noted that the pump unit 10 is mounted in a well casing 176 with the operating rod 58 extending above the hollow housing 116 and terminating in a \'-belt pulley 178 which may be connected with any suitable power source for driving the pump unit 10'. The pump unit 10' is identical to the pump unit 10 except for the differences shown specifically in FIGURE 6 and for the addition of a supporting and bearing construction for the shaft 58' with this structure being generally designated by the numeral 180 which is disposed in vertically spaced relation to the pump unit 10'.

Referring specifically to FIGURE 6, it is noted that a collar 182 is screw threaded onto the threaded end 102' of the fitting 100'. The member 182 is provided with an outwardly extending flange 184 at its lower end which receives and clamps an inwardly extending flange 186 on a generally cylindrical sealing gasket 138 made of leather or similar gasket material with the upper edge of the sealing gasket 188 being feathered as indicated by the numeral 190 whereby water engaging the feathered edge and between the gasket 190 and the member 182 will urge the gasket 180 outwardly into engagement with the casing 176 thus sealing the pump unit so that the carrier of the casing above the pump unit will act as a flow pipe for the water pumped by the pump unit. Other than this addition, the pump units in FIGURE and FIGURE 3 are identical. It is also pointed out that the flange 108 has been removed from between the fitting 100 and the adapter 40 in the construction of FIGURE 5 since this flange is not employed in this orientation with the flange being removed and the sealing gasket 188 and the cylindrical member 182 fitted thereon. The member 182 is also internally threaded as indicated by numeral 192 for permitting a multiplicity of the pump units to be hooked together in tandem relation.

Referring now specifically to FIGURES 7 and 8, the supporting and bearing mechanism 180 for the shaft 58 is set forth as including a cylindrical sleeve 194 having a pair of diametrically opposed radial sleeves 196 formed thereon for slidably receiving an inwardly extending projection 198 on an arcuate brake shoe 200 having friction producing material 202 on the outer surface thereof. A compression coil spring 204 encircles each of the sleeves 196 for urging the brake shoe outwardly into engagement with the casing 176 for preventing rotation of the sleeve 194 and also providing support for the sleeve 194.

The sleeve 194 is provided with a central bore 204 having a recess 206 therein for receiving a felt filter 208 with the bore 204 receiving a cylindrical bushing 210. The sleeve 194 is provided with radially extending apertures 212 communicating with the recess 206 and the bushing 210 is provided with apertures 214 for supplying lubricating liquid to the outer surface of the shaft 58 for lubricating the same. The outer ends of the sleeve 194 are each provided with a sealing member 216 having an O-ring 218 between the sealing cap 216 and the bushing 194 and also an O-ring 220 between the shaft 58' and the sealing cap 216. Each of the sealing caps 216 are disposed adjacent a collar 222 secured to the shaft 58 by a setscrew 222. If desirable, the flat ends of the sealing caps 216 may be altered to any suitable shape such as the shape of the sealing cap 72 in the construction of FIGURE 3 with the collar having a complementary bearing surface for centralizing the elements and maintaining a contact therebetween.

The construction in FIGURE 10 is substantially the same as that employed in the construction of FIGURE 5 with the exception that the sealing gasket 188 has been eliminated and the pump unit designated generally by the numeral 10" may be disposed in a well bore 224 of any diameter with there being no contact between the pump unit 10" and the well bore. In this construction, the cylindrical member 182 is attached directly to a flow pipe 226 which extends upwardly and is attached to the housing 116" by attaching flanges 228. In this installation, there is no need and no utility for the sealing gasket 188 and this may be eliminated or if it is desirable, may be left in position with this gasket then being inoperative. This enables the pump unit 10" to be employed with large bore wells either of the shallow well type or of the deep well type having a relatively large bore wherein it would not be feasible to provide a pump of that diameter. This also enables the pump to be employed with well casings of different diameters with the pump unit being supported from the flow pipe 26 with the casing or housing 116" being supported by any suitable mechanism or supporting base, the details of which are not shown.

The suction pipe 158 is provided with a strainer and a foot valve assembly 159 and an eye 157 for engagement with a cable 155 entrained over a hand operated Winch 153 that is supported on an A-frame 151.

The operation of the unit will appear self-evident. Water enters the central area of the impeller 82 and is caused to move radially and axially outwardly and inwardly by the spirally curved blades 88 on the impeller. The depending ends of the blades or vanes 50 of the deflector form a socket for receiving the upper end of the impeller 82 in close proximity thereto for receiving the water therefrom. The spiral curvature of the blades or vanes 50 causes the rotational and centrifugal motion of the water to be converted into axial force thus causing the water to flow substantially axially along the sleeve casing 36 at which time it is picked up by the second impeller and additional rotary movement given thereto which will assist in the discharge of the water from the outlet conduit 126. By employing a multiplicity of the units, the desired pressure and lift may be obtained.

The present application is a refiling of the application of Ethridge F. Ogles, Serial No. 661,395, filed May 24, 1957, for Combination Deep Well and Portable Irrigation Pump.
