12 Claims. (Cl. 166-85) My invention relates to water pumping apparatus of the type known as pitless adapters or pitless pumps where the operating parts and discharge points are located in the ground below the frost line. No pit is used with such apparatus since parts are inserted into and withdrawn from the well casing which has an extension above surface level for that purpose.
More particularly this invention contemplates improvements in the underground discharge coupling for effecting better sealing engagement with the discharge outlet in the casing.
Another important object herein is to provide an underground discharge coupling assembly for a pitless adapter pump that can be easily inserted into and withdrawn from a well casing and includes novel means for biasing the same into and out of sealing engagement with the underground discharge outlet.
A further object inhering herein includes improved means for suspending and supporting the adapter assembly within the well casing.
Still another object of this invention is to provide improved means for aligning the discharge coupling with the discharge outlet in a pitless adapter.
`Other objects and advantages of this invention reside in the details of construction and correlation of the various parts and will be apparent as the description proceeds.
This invention consists of novel parts and combination of parts `to be hereinafter described whereby the objects set forth are attained, as pointed out in the claims, and illustrated in the accompanying drawings, in which:
Fig. 1 is an exploded perspective view of a preferred embodiment of this invention,
Fig. 2 is a longitudinal sectional view thereof showing the discharge coupling inserted in the well casing in alignment with the discharge outlet but not yet in sealing engagement therewith.
Fig. 3 is a view similar to Fig. 2 but showing the discharge coupling after it has been biased into sealing engagement with the discharge outlet, and
Fig. 4 is a fragmentary View, partly in section, of the top of the pull pipe and associated parts showing the use of the cap engaging eye bolt in Figs. 2 and 3 being used for connection to the pull pipe only when the cap has been removed.
Referring to the drawings the usual well casing 1i) is shown relative to ground level 12 Fig. 2) with the underground discharge pipe 14 to which the underground discharge pipe extension 16 is suitably connected. Such parts are standard in devices of this type and member 14 is in eiect a stub pipe that may be welded to or clamped on casing to register with and terminate in a ltapered opening or orifice 18 therein and to provide a supporting connecting means for line 16 as shown. An annular support ring or plate 20 is provided with a peripheral shoulder 22 by which it rests on and is supported by the top edge 24 of casing 10. A lug or boss 26 projecting from the perimeter of plate 20 (Fig. l) seats in a notch 28 provided in the top of casing 10 and prevents any rotary movement of such plate relative to the casing 10. Plate or ring 2t) supports all of the structure of this invention within the casing 10 in a novel manner as will later appear.
A pull pipe 30 is removably attached at its upper end to plate 20 by a cap 32 or other suitable means so as to depend therefrom in axial alignment, and at its lower end is threadably attached to the upper end of a block-hice housing 34 with the lock nut 36. rlhe lower portion of housing'34 s'provided with an inverted L -shaped passage- Way 38 which includes the threaded opening 4d at the bottom for receiving the drop pipe 42 that connects to a pump (not shown) and the side opening 44 which communicates with what I have called the sealing L 46'. The L 46 is in eiect a boss-like projection from the side of housing 34 and terminates in a tapered or beveled face 48 designed to seat in the opening 16 of pipe 14. An O ring seal 50 is mounted on or in face 48 to provide a iiuid tight seal at this point. `It should be mentioned here that the distance between the top edge 24 of pipe 16 and the underground discharge pipe 14 may vary in different installations and thus the length of`pull pipe 30 will be such that L 46- will he in position to register with pipe 14 (Fig. 2) when cap 20 is placed on pipe 16. Notch 23 in edge 24 of pipe 10 is in vertical alignment with pipe 14 and lug 26 on plate or ring 2li is similarly arranged relative to L 46 soV that by seating lug 26 in notch 2S', L 46 is accurately aligned with pipe 14. Means for moving L 46 into and out of sealing engagement with pipe 14 is one of the impoltant aspects of this invention and is accomplished in the followingmanner.
A pair of like elongated tiat guide plates 52 (Fig. 1) each having what I shall callv the respective front 54 and rear 56 edges are rigidly connected by bar 5S so as to be maintained in parallel spaced relationship in such a manner that each` plate 52 is disposed closely adjacent one of two opposite sides of housing 34' as shown. In this position the face 48 of L 46 projects slightly beyond the front edges 54 and the rear edges 56 are substantially in alignment with the edge of housing 34 opposite to L 46. Each plate 52 is provided with a diagonal slot 60 extending from the bottom thereof near edge 56 upwardly towards and terminating near edge 54 'and a lug or boss 62 on each respective side of housing 34 adjacent the plates 52 projects intoY the respective slots 60. The diameter of such lugs are such that slots 60 are in slidable engagement therewith as will later appear. An adjusting rod 64 is connected at one end to bar 5S by any suitable means which is illustrated here as a fitting 66 on bar 58 to which rod 64' may be removably or permanently attached. The main length of rod 64 is parallel to the pull pipe 30 with its other or upper end being externally threaded 68 and projecting upwardly through the support ring 20 and through a platform member 7i) mounted thereon. An adjusting nut 72 is placed on rod 64 above platform 70 and washers 74 may be used as shown. By rotation of nut 72 in two opposite directions respectively, rod 64 isk moved either upwardly or downwardly relative to ring 20, the drop pipe 30, housing 34 and L 46 and thus plates 512 being secured to rod 64 are correspondingly moved relative to the same numbered parts. Such relative movement of plates 52 moves the diagonal slots 60 against the lugs 62 to bias the L 46 toward and away from opening 18 in pipe 14 as desired.
For inserting and removing L 46 and its associated parts relative to casing 10, rod 64 and plates 52 will be elevated suiiciently so that the lower end of slots 60 are embracing the lugs 62. In this position, lugs 62 are far enough from edges 54- of plates 52 that the L 46 has adequate clearance within pipe '10 to permit easy insertion or withdrawal of the entire assembly. Once inserted, however, the L 46 will be opposite port 14 (Fig. 2) and cannot be turned out of such alignment Patented Aug. 23, 1960i because of the lug 26 resting in notch 28 in edge 24 of pipe as previously described. Nut 72 is then rotated to lower rod 64 and plates 52 whereby slots 60 more past lugs 62 in slidable engagement therewith causing the L 46 to be biased into sealing contact with opening 18 of port 14 as seen in Fig. 3. During this process, the rear edges 56 of plates S2 will bear against the adjacent inner lsurface of pipe 10 and the top edge 24 of pipe 10 will 1n effect serve as a pivot or hinge point for the support ring 20 to permit the slight lateral movement of pipe 30 and housing 34. To unseal the L 46 from opening 18 in pipe 14, rod 64 is elevated reversing the action of plates 52 on lugs 62 and here the forward edges 54 of plates 52 will bear against the adjacent inner surface of the casing 10.
For the top of casing 10 a suitable cap 76 is provided which includes a resilient sealing ring 78 for frictional engagement with the outer surface of casing 10 near edge 24. Cap 76 contains an opening 80 for passage of an electrical conduit 82 which is required for the pump (not shown) in a well known manner, and an eye bolt 84 extending through cap 76, cap 32 and into pull pipe 30 is used to supplement the frictional attachment of cap 76 to pipe 10. Bolt 84 is also usable when cap 76 is removed for direct attachment to pipe 30 (Fig. 4) to facilitate the removal of ring 2t) and its attached parts.
It is submitted that the invention shown and described is aptly suited to achieve the purposes intended and its characterized by a combination of highly useful and mutually cooperating elements that combine their respective and proportionate functions in accomplishing the objects sought to be obtained.
It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes in the construction and arrangement of this invention can be made within the scope of what is claimed, without departing from the spirit and purpose thereof. It is thus intended to cover by the claims, any modied forms of structure or mechanical equivalents which may be reasonably included within their scope.
