' DEEP-WELL PUMP.
Application filed July 2,
My invention relates to improvements in d e3 well pumps, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide a deep well pump that is adapted to automatically take up the wear between the plunger and the cylinder wall, whereby leakage between these parts is prevented. Y
A further object of my invention is to provide a device of the type described that has a packing which is adapted to prevent. sand from becoming lodged between the plunger and the barrel. i
A further object of my invention is to provide a device of the type described, which is simple in construction, durable and ethcient for ,the purpose intended, and which is not likely to get out of order easily.
- Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointedout in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this application, in which Figure 1 is a vertical section through the device, portions thereof being shown in elevation,
Figure 2 is a section along ,the line 2f-2 oi' Figure 1,
Figure 3 is a detail view of a modified form of the paching-compressing member, and
Figure l is another modified form of a packing-conipressing member.
In carrying out my invention 1 provide a deep well pump that consists of a housing 1 having longiti Vl:wally extending rows of teeth 2 cut in s inner surface. A housing is permanen y secured to the housing 1 and has a smooth inner wall 4. A coupling` secures the pump to the well tubing. A plunger T is slidably disposed in the housings 1 and 3 and extends into the pump barrel extension 8. The extension 8 is secured to `the housing 3 by means of a coupling 9.
l provide a packing 10 that is disposed in the housing 3, this packing being supported by a ring 11, and in turn supporting a sleeve or ring 12. The sleeve 12 has a tapered under surface 13, this surface bearing against the packing 10. 1t is obvious that .the packing will become worn through use, and I therefore provide a novel means for automatically compressing the packing to a 1923. Serial No. 649,137.
greater extent so that the packing always fills the space between the surface et and the plunger 7'. A collar 14 is slidably disposed upon the plunger 7 and bears against the top ot the sleeve 12. The collar has recesses 15 in its outer surface, these recesses receiving pawls 16, The pawls 16 have teeth 17 that are adapted vto engage with the teeth 2 -to prevent upward movement of the collar 14 with respect to the housing 1. 1t will be noted that the teeth 2 and 17 are shaped so as to permit downward movement of the pawls with respect to the housing 1, but'will prevent upward movement of the pawls. Springs 18 disposed in the recesses 15 yieldingly engage with the pawls 16.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The plunger is connected to rod 19 that extends to the top of the well. The rod 19 is actuated in the ordinary manner so as to pump oil into the tubing 6. The plunger 7 is provided with a valve cage 2O at its upper end, the cage projecting `beyond the outer surface of the plunger and being adapted to abut thetop of the collar 14. During the operation of the device, the cage 2O strikes the collar 14 each time the plunger is moved downwardly. In oil pumping machinery, the lower limit of movement is determined by the cage 2O striking the collar 14, and this limit changes as the collar is moved downwardly. The depth of the packing 1() is not so great as to prevent the rods 19 from causing the sleeve 12 to keep the packing compressed until the last bit is used. The collar in turn drives the sleeve 12 downwardly against the packing 1() so as to take up the wear between the wall 4 and the plunger 7. The collar 14 is held after being driven downwardly by means of the pawls 16 engaging with the teeth 2. In this manner any wear is automatically taken up as the device operates. The sleeve 12 can be moved downwardly the entire length of the packing 1() lif the packing is worn away to this extent, the pawl 16 holding the sleeve and collar in the lowermost position to which they are moved by the cage 20. An inlet valve 21 is carried by the extension 8. The plunger 7 moving upwardly opens the valve 21 and in moving downwardly opens the valve 20. Y
The compressing of the packing 10 so as to make a leak-proof jointbetween the age causes the oil to cut up, thus pre.
' venting the oil from being used as `tiret-class sumed in fixing the pump.
oil. rihe packing l also prevents sand from becoming disposed between the plunger and the wall o'l' the cylinder, 'thereby greatly increasing the iiie ot the pump. Moreover, the time and labor saved in working the pump all ot the time instead of having te remove the pump trom the well 'from time to time so as to tix the same is a big factor and also saves a large quantity of oil which would be lost during the time con In Figures and il have shown a niodiiicd 'forni t' the pawls i6. In Figure 3 I have shown the pawls as consisting of springs BO that are adapted to engage with the teeth 2te prevent upward movement of the collar le but to permit downward movement ot the collar. In Figure 4 I have shown the pawls I0 as being received in the recesses il that have cam surfaces ft2. A spring 43 bears against the pawls t() and holds the pawls in engagementwith the teeth 2.
In case the sleeveV li'is notl moved down rapidly 'enough to compress the packing as the latter is worn, I can lower the pump rod so as to have the sleeve support the' Vweight of the rod insteadv otthe pumping mechanism at the top of the weli; The weight of the rod is sufficient to move the sleeve ld downwardly to compress the packing lO. This operation can be .repeated once or twice a month or as etten as needed. It will be noted that some wells have more Heating sand than others which wears out the packing faster that the sand does in other wells.
l' Claim:
l. A deep well pump comprising a housing having longitudinally extending rows ot' teeth in its interior wall, a plunger having an enlarged portion at its uppermost end and arranged for movement in a reciprocatory pat-h within said housing, a disk,
packing carried by said disk, said packing being disposed between said plunger and said housing, a sleeve slidably disposed within said housing and carried by said packing, said sleeve being concentrically disposed with respect to said plunger and arranged to engage said housing, a collar having longitudinal recesses adjacent the longitudinally extending rows of teeth in said housing, the collar being slidably disposed wit-hin said housing and carried by said sleeve, and dogs disposed within the recesses in said collar and having ratchet teeth arranged to engage with the longitudina'dly extending rows oi' teeth in said housing to prevent movement of the collar in one direction with-respect to said housing.
