Application filed September 8, 1920. Serial No. 408,943.
To (ZZZ whom it may concern Be it known that we, MAIILON E. LAYNE and SAMUEL N. HALL, both citizens of the' The invention relates to well mechanism and particularly to rotary or centrifugal I pump mechanism involving the use'of a pump placed inor adjacent the water of a well and transmission and discharge mechanism extending to the surface of the ground. The invention has. for its primary ob ects:
the provision of improved means for packing the pump casing in the well casing: (2) the provision of means whereby .the packing canbe adjustedand tightened from the surface of tl.e ground; (3) the provision of packing means of the type specified which can be applied at the upper por'-- tions of the pum casingso that it can be applied to a multi-stage pump without providing pockets for the accumulation of sand between the pump and well casings which would tend to prevent the ready removal of the pump for replacement ofrepair; and
'the provision of a packing means which does not prevent the suspension of the pump from the discharge and shaft casings whereby such casings are subject to tension tending to hold them straight; Certain embodiments of the invention are illustrated in the accompanying drawings, wherein1' Fig. 1 is an assembly view. largely in a vertical section showing the application of the improvement to a pump. Fig. 2 is an enlarged partial vertical section and partial elevation taken through the apparatus to which the improvement is applied. Fig. 3
is an enlarged vertical section showing one formof coupling which may be employed. Fig. 4 is a transverse section at IV-IV of Fig. 3, and Fig. -5 is. a vertical section through a modified form of coupling which mag be employed.
eferring first to the general arrangement the principal parts of the pump may be enumerated as follows: 1 is the pump casing carrying the runners or impellers 2 keyed to the drive shaft 3 4 is the well casing which also acts as a disbharge casin and extends to the surface of the roun discharging through the lateral out et 5; 6
is the shaft casin extending from the pump neck to the platfhrm 7 at which point it is connected to the casting 8 by means of a coupling 9; l are leaf springs for preventing the pump from turning in the well'casing; and 11 is the drive pulley by means of which the shaft '3 is driven.
The feature to which the invention is particularly directed is shown in Fig. 2 and comprises the improved means whereby the pump casing is packed with respect to the casing 4 so that such casing may act as a discharge casing as well as a well casing. 'lhearrangement is such that the packing may be tightened or loosened by rotation of the shaft casing. a nut being swiveled upon the lower end of the shaft casing and connected to the land or presser memberof the packing device so that such presser means may be moved up and down. This packing device is arranged adjacent the upper endof the pump casing so that no pocket is. formed between the pump casing and the Patented May a, wee.
well casing and there is no opportunity for a deposit of sand or dirt between the casings such as is the case where a pump is packed by allowing it to rest upon a pack.- ing device at the bottom of a Well casing, this latter construction rendering the pump diflicult of removal after, the space has been filled with sand or dirt, particularly with a multi-stage pump. The arrangement also permits the main portion of the weight of the pump and the column of water above'it to, be suspended from the shaft casing 6, thus tending to keep it straight, which is not the case in a construction in which the weight of a pump is supported by setting the pump upon the bottom of a well. The present construction is, therefore, applicable to multi-stage pumps and deepnvell work.
A seat 12 is provided adjacent the upper portion of the pump casingv which seat carries the packing 13. This packing may be of rubber or any other suitable composition inner ends internally threaded sleeve 18. The sleeve 18 is threaded to the sleeve 19 which in turn is secured by the bolts 20 to the sleeve 21. In order to keep the water and sand from working in between the sleeve 18 and'the sleeve 19 the packing 22 is provided, held in place by the collar 23.
The sleeve 21 is bolted at its upper end to the coupling member 24 by means of the bolts 25 and the coupling member 24: together with the externally threaded bearings 26 serves to-secure the sleeve 21 to the lower end of the shaft casing 6. To prevent the lower end of the shaft casing 6 unscrewing a split tapering sleeve 27 is employed, such sleeve being driven tightly into a recessbetween the sleeve 24 and the shaft casing 6 as indicated in the drawing. it will be seen that the sleeve 21 forms in effect a continuation of the shaft casing and that such section is swiveled in the hollow casting 28 forming the inner part of the pump casing,
the extreme lower end of the sleeve 21 being turned outwardly as indicated at 29. Brass bushings 30 and 31 are employed between the member 28 and lower end of the sleeve 21 so as to prevent sticking such as would occur if the iron of the member 28 came directly in contact with the iron sleeve. Packing 32 is also provided above the bushirn 30 in order to 'keep out sand and water. 7 in assembling the apparatus after the well casing has been installed, the pump is lowered to its desired position supported by the shaft casing '6, the sleeve18 which carries the gland being screwed up at such time so that there is no pressure on the packing 13. When-the pump reaches the proper level in the casing, a proper turning tool, such as a pipe Wrench, is applied to the upper end of the shaft casing and it is rotated to screw the sleeve 18 downward, thus carrying the gland 14 downward against the packing and compressing it laterally-so asto form a sealing joint between the casing 4 and the pump. When it is desired to remove the pump from the well for replacement or repair of any of its parts, the shaftcasing is rotated backwardly thus causing the sleeve 18 to move upward and release the packing, after which the pump, may be pulled from the well in the usual way. In case the shaft casing 6 should becomebroken it would still be possible to loosen the packing by lowering an internally threaded sleeve and causing it to engage the threaded surface 33 of the coupling 'member24, after which-the sleeve 21 could be rotated to loosen the packing. A
, sired construction.
suitable bearing in the pump neck is pro v ded in the form of the brass or composition member 34, which may be of any de- In order to prevent the shaftcasing-from unscrewing where its sectionsare jointed together, the types of couplings shown in Figs.
3 and 5 may be employed. The coupling shown in Fig. 3 comprises a split sleeve member 35 clamped in position by the bolt 36 and sawed laterally and vertically as indicated at 37 and 38 so as to give the necessary flexibility to the coupling to permit it being clamped in position. y
In the construction of Fig. 5 the coupling 39 is either riveted in place at one end as indicated at 40 or spot-welded, while the upper portion is provided with a taper ng recess adapted to receive the split taperlng wedge 41, which is either tightly driven or screwed. into position. Qouplins oh the foregoing types serve to permit he casing to be rotated in order to adjust the gland for packing the pump up and down, considerable force being required in some cases to accomplish this result so that very secure connections at the joints of the shaft casing are necessary.
