Dak. 587 01 Filed Nov. 14, 1966, Ser. No. 594,047 2 Claims. (Cl. 103-202) ABSTRACT F THE DISCLOSURE The invention comprises and elongated removable well pumping device adapted to be introduced into a well tubing of a well comprising an elongated pipe structure with a pump at the lower end, a plurality of annular resilient collar-like sealers at spaced intervals along the length of the pipe structure with the uppermost one of said Sealers set below the rst line, a horizontal outlet connected to the well tubing below the uppermost sealer.

This invention relates to well equipment, more particularly, the invention relates to my earlier copending patent application U.S. Ser. No. 484,235, led Sept. 1, 1965 for Pressure Pumping Device.

It is an object of this invention to provide a novel tankless, pitless pumping device.

It is a further object of this invention to provide a tankless pump device which does not require a tank to operate and which will dispense the water from the well below the frost line.

Further objects and advantages of the invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawing wherein:

FIGURE 1 is a side elevational view of the tankless pitless pump device with portions broken away to reveal the interior of the tankless device.

FIGURE 2 is a cross-sectional view taken along line 2-2 of FIGURE 1.

FIGURE 3 is an enlarged cut away view of one of the annular sealers.

FIGURE 4 is an enlarged cut away view of the upper end of the tankless pitless invention.

FIGURE 5 is an enlarged fragmentary showing of the rubber collar and well tubing.

Briey stated, the invention comprises a tankless pump device having an elongated vertical pipe with a pump at the lower end of the pipe adapted to be introduced into the ground, three rubber collars mounted at spaced intervals along the length of the pipe, with the uppermost collar adapted to be set below the frost line, a second and third lower collars adapted to be set in spaced relation in the well to form a tank reservoir and with the water adapted to be pumped out of the well below the uppermost collar and thus below the frost line in the earth.

Referring more particularly to the drawing in FIG- URE 1, the tankless pitless pump device 20 is shown installed within the well tubing 21 of a water well 22 beneath the surface 23 of the ground.

The tankless pitless pump 20 has a central pipe structure 24, with three

rubber collars

25, 26, and 27 mounted over the enlarged

cylinder portions

28, 29, and 30 of the central pipe structure 24. Three

coil springs

31, 32, and 33 are mounted to the pipe structure 24 along its reduced neck portion 28', 29', and 30 and act to urge the rubber collars downward.

Installation The

rubber collars

25, 26, and 27, when in their position illustrated in FIGURE l, create three water tight annular seals between the pipe structure 24 and the well tubing at spaced intervals.

When installing the pump 20 in a well, the central pipe structure 24 will be lowered into the well, the

collars

25, 26, and 27 will initially be located above their position illustrated in FIGURE 1 so that the lower edges 25', 26', and 27 of the rubber collars will be urged to engage between the upper portions of the enlarged

cylindrical portions

28, 29, and 30 and the well tubing 21, by the springs being partially compressed by the collars and urging the collars downward.

However, as long as the pipe structure 24 is sliding downward in the well, the frictional reaction of the rubber collars with the well tubing will push the collars upward so that they do not create a seal or freeze between the well tubing and the enlarged cylindrical portions.

The pipe structure will be lowered to the desired depth and then pulled back vup a short distance. The pulling of the pipe structure back up a short distance, will draw the rubber collars fully down onto the enlarged cylindrical portions to their position illustrated in FIG- URE 1, where they create a water tight seal.

When it is desired to remove the pump device, the pipe structure 24 will simply be pulled up, which will cause the collars to slide downward relative to the pipe 24, from their position illustrated in FIGURE l, onto the reduced

neck portions

29', 34, and 35 which allows them to contract at least to a certain extent. The collar 25 in moving downward relative to the pipe will compress spring 32, to a certain extent, and the collar 25 will contract to a certain extent, the

collars

26 and 27 will slide down about

pipe portions

34 and 35 and contract, and the catch plate 36 has four radial fingers 37 which will catch collar 27.

The pipe structure 24 installed by being lowered past the desired level, which level will be such that seal or collar 25 will be located below the frost line 38, whereupon the pipe structure will be raised a short distance causing the

collars

25, 26, and 27 to slide downward to their positions shown in FIGURE 1, which creates three seals by the collars. The rst seal is below the frost line, the second seal 26 is below the outlet pipe 39, and the third seal 27 is spaced below collar 26 to `form a tank reservoir of the height and corresponding capacity desired. The pump (not shown) is mounted to the lower end 35' of the pipe structure 24.

Within the pipe structure 24 is a cut off wall member 40 which directs the tlow from the pipe section 24 out orifice 41 into the outlet pipe 39, and prevents water from the pipe portion 34 of the pipe structure 24 coming up directly from the pump, from going above the outlet pipe 39 and allows it only to go out the outlet pipe 39.

Also, a metal support control block 42 is threaded onto the pipe structure 24 at the top along location 42'. The control block has a pressure gauge 42 mounted to the block which communicates with the interior, and a conventional pressure switch mounted within the container 43 which communicates with the interior of the pipe 24 by the conduit 44 and a conventional one way valve or sniffer valve within the container 43 which also communicates with the interior of the pipe 24 by the conduit 44.

Air is pumped in initially into the top portion of the pipe 24 through the sniffer valve in the container 43 and via conduit 44 to create air pressure in the pipe and to keep the water in the tank area (between seal 26 and 27) under pressure.

The pump will pump water up into the tank reservoir

area inbetween seal

26 and 27 via orifice 45 and up along the central pipe portion 34 of pipe structure 24 and out the conduit 39, vla the oriiice 41 in the pipe structure 24. The water is also free to travel up the pipe via the 4opening 46 for the electric cord, however, air will be pumped in through the snilier valve to create air pressure in the top portion of the pipe structure 24 to maintain the water down in the reservoir area.

The air is pumped into the pipe structure 24 from the top to keep the water in the tank area (between seal 26 and 27) under pressure so that it will force water out of the reservoir area and out through orice 41 and along pipe 39. When the Water pressure gets lower, it will also cause a corresponding drop in the air pressure. When the air pressure drops below a desired minimum, it will activate the pressure switch in the container 43 (via conduit 44) at the top of the pipe. The activation of the pressure switch will activate the pump which will begin pumping more water up into the pipe structure to bring the pressure back up to its desired upper limit, and the pressure switch will automatically turn the pump off again.

The water from the pipe structure 24 and tank area will pass out of the pipe structure along pipe 39 at a rate determined by the size of orice 41.

The electric cord 46 extends from the pump up along the outside of the pipe structure 24 until it reaches a location just below seal 27, where it enters through a rubber grommet seal 47, similar to the rubber grommet seal 48 at the top of the pipe, and a threaded plug 49, similar to the plug S at the top of the pipe. The plug 49 has a center slot to receive the cord and as it is threaded into the pipe structure it squeezes the grommet together and creates a water tight seal. Similarly, tightening the plug 50 at the top of the pipe creates a water tight seal.

The

rubber collars

25, 26, and 27 have a plurality of elongated ribs l. extending along their lengths which compress together to form a water tight seal when on the enlarged

cylindrical portions

28, 29, and 30, respectively. The ribs also act to prevent the collars from freezing or adhering to the pipe walls when they have been expanded, and when it is desired to remove the pipe structure and collars from the well.

A cover 52 covers the control block 42, container 43, pressure gauge 42", and is attached to the well tubing 21 by bolts 53. A cap 54 has a projecting flange 55 which rests on top of the well tubing 21 and Supports the pipe structure 24.

The invention may be operated without the tank reservoir area. The seal 27 would not be used in the device, and the pump would merely activate everytime water was to be pumped out from the well.

Thus, it will be seen that a novel tankless pitless pump system has been provided which can be easily mounted in a well and will pump water from the well below the rost line, to the point of consumption or use, and which creates a pressure tank area (between seals 26 and 27) 4- to cause the water to be fed out under pressure, and so that the pump does not have to pump continually.

It will be obvious that various changes and departures may be made in the invention without departing from the spirit and scope thereof and accordingly it is not intended that the invention be limited to that specically described in the speciiication or illustrated in the drawings but only as set forth in the appended claims.
