ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to adaptors on water-well heads for attachment of separate pumps to well casing plates.
There are a plurality of known different sizes and structures of surface pumps for water wells having casing plates. Four-inch casing is most common for supplying water for use requirements in the approximate range of a dwelling for a single family. Each of these surface pumps is attachable to a separate well-top casing plate that is affixed to a top end of the casing. To change from one size and/or structure of surface pump to another size and/or structure of surface pump with a replacement pump, it is necessary now to first remove the existing casing by pulling it out. Then it is necessary to replace the removed casing with a different casing having a different affixed well-top plate with two different well-head orifices and often two different plate-fastener orifices that match two separate pump-element orifices and two separate pump-fastener orifices of the replacement pump.
Pulling out existing casing and pounding replacement casing back into a well just to be able to attach a different pump to a different well-top plate is costly and time-consuming. In addition, it is often prohibitive as a result of surrounding structure and circumstances.
There are known well-head adaptors for different aspects of well heads, but none known that address, relate to or solve the problem of adapting different pumps to an existing well-head plate as taught by this invention.
SUMMARY OF THE INVENTION
Objects of patentable novelty and utility taught by this invention are to provide a water-well-head adaptor which can be made for attachment to a predetermined class of well-head plates and for attachment of a predetermined class of well-water pumps.
This invention accomplishes these and other objectives with a water-well-head adaptor having an adaptor body with matching plate-fastener orifices and matching pump-element apertures. The plate-fastener orifices match well-plate attachment orifices in a predetermined class of well-head plates on an adaptor-bottom surface and match pump attachment orifices in a predetermined class of well pumps on an adaptor-top surface. The pump-element apertures match plate apertures in a predetermined class of well-head plates on the adaptor-bottom side and match pump-element apertures in bottoms of a predetermine class of well pumps on the adaptor-top surface. The adaptor-bottom surface and the adaptor-top surface are parallel and separated a predetermined distance apart.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.
