| A device for cleaning, widening and repairing of wells comprises a pipe for supplying, through a valve, compressed-air into the well and a water and air discharge pipe coaxially surrounding the air supply pipe and terminating at its upper end with a bell airtightly welded to the periphery of the air supply pipe. The water and air discharge pipe as its upper part has a first port communicating with a water discharge pipe through a valve and a second port communicating with an air discharge pipe through another valve. A head surrounds the upper portion of the water and air discharge pipe and at its upper end is airtightly welded to the periphery of the water and air discharge pipe and at its lower end terminates in a flange detachably secured to the upper end of the well-jacket. The head has a third port communicating through a valve with a pipe for discharging and similar purposes. Moreover, there are provided two annular rubber diaphragms for defining in the depth of the well the zone in which the compressed-air has to be blown for widening the well and other elements to remove deposits, stones and putrid waters. Another device is provided for removal of the pebble gravel of the well-filter and earth blocks clogging the well-filter. | ||||||

| 124 | Well capping assembly | US48853874 | 1974-07-15 | US3875999A | 1975-04-08 | LIBERG JOHN E |
| A well capping assembly in which a cylindrical cap is fitted into an annular well casing head and is formed with a pair of vertical passages. Lines are sealed to one passage to convey water under pressure through the cap, and an opening directs water from that passage to a sealing groove between a pair of seals fitted between the cap and the casing. In the second passage, an assembly is fitted for sealing a second pair of seals around a conduit running through that passage, and openings direct water under pressure from the sealing groove to a second sealing groove defined between the second pair of seals. Alternatively, the assembly and conduit can be removed from the second passage and lines sealed to that passage so that a pair of water pressure lines pass through the cap.

| 126 | Pitless well adapter | US37285873 | 1973-06-22 | US3847217A | 1974-11-12 | KRAMER D; CRAWFORD J |
| A pitless well adapter includes a mounting member which is positioned against the inner surface of the well casing, and which has a nipple that projects through an opening in the well casing. A coupling member is connected to the well pipe and is releasably connected to the mounting member by coacting tapered guide elements to thereby interconnect the well pipe to a delivery pipe which is connected to the nipple of the mounting member. An interior sealing element and an exterior sealing element are positioned around the exterior surface of the nipple and against the inner and outer surface of the well casing adjacent the opening therein to form a pressure passage around the exterior surface of the nipple and edge of the opening in the casing. A connecting passage connects the interior of the nipple with the pressure passage so that the seals formed by the sealing elements are under system pressure. A clamping member or washer and a clamping nut clamp the sealing elements against the well casing and nipple, and also secure the entire adapter to the well casing.

| 129 | Pitless well adaptor | US3782462D | 1972-04-28 | US3782462A | 1974-01-01 | KRAMER D |
| A pitless well adaptor includes a casing engaging member or saddle which is clamped against the well casing and around the opening therein, and is connected to a horizontal delivery pipe. A pair of positioning elements on the casing engaging member permit the latter to be properly orientated with respect to opening in the casing, and a pair of annular sealing elements are interposed between the exterior surface of the casing and the casing engaging member to form a seal thereat. The annular space between the sealing elements defines a pressure passage which communicates with the main passage through the adaptor so that the external seal is under system pressure. A coupling member, which is connected to the well pipe, is releasably interconnected to the casing engaging member by coacting tapered guide elements to thereby intercommunicate the well pipe to the delivery pipe.

| In the case of a jet pump water system two round holes are cut in the well casing below the frostline. A casing fitting is attached fluid-tight to the casing around the two holes. The casing fitting has pressure and suction cylindrical recesses located beyond the inner wall of the casing, coaxial with the casing holes. Pressure and suction pipes are connected to the pressure and suction recesses and extend horizontally below the frostline into a dwelling to a pump and a water delivery conduit. A drop fitting has pressure and suction conduit necks which fit fluid-tight into the pressure and suction recesses. An inner assembly has drop and jet diffuser fittings at the top and bottom respectively of pressure and suction drop pipes. The inner assembly is lowered into the well with the pressure and suction conduit necks pointed in the direction of the conduit recesses. When the necks reach approximate alignment with the recesses an actuator automatically inserts the necks into the recesses and rigidly locks them in. Thus, the pressure and suction pipes and drop pipes are coupled fluid-tight and the inner assembly is rigidly supported. To remove the inner assembly, it is first additionally supported with a hoist, then the conduit necks are withdrawn from the recesses by a manual lift on a control cable (which reverses the actuator) and the inner assembly is lifted out with the hoist. The casing fitting and the drop fitting, which includes the actuator, comprise the invented pitless well adapter.
