NVENTOR. WILLIAM WELLSTElN ATTORNEY PIPE CASING SIDE CONNECTOR RELATED APPLICATIONS Thisis an improvement over applicant Wellsteins corresponding U.S. Pat. No. 3,430,697 issued Mar. 4, 1969.

FIELD OF INVENTION This invention relates'to means for assembling and disassembling a connecting means for a duct through a hole in the side of a casing and means for aiding insertion of the connector into or removing it from the casing. A common application for such a connecting means is found in modern water well systems wherein a number of functional parts deep within the well casing cooperate to transmit fluid from the well through an encased duct or ducts Iatterly through a hole in the wall of a well easing which hole may be located a substantial distance below the top ofthe well casing and `usually is located a sufficient depth below the surface of the ground to avoid freezing and other superficial hazards.

One problem of prime importance is the sealing of the below the surface casing hole when detachably connecting means is used, which will satisfy various local installation codes and which will prevent the infiltration of surface water and such accompanying impurities as might be found near barnyards or areas wherein septic tanks are used. For systems of this type there is a substantial advantage in having a connecting means which may be manipulated from the top of the casing to readily join or disjoin internal components of the system from a lateral external duct and thereby permit installation or removal of the internal components through the top of the casing located above the ground. Such a connecting means facilitates the servicing of the functional parts within the well without dismantling the balance ofthe system.

SUMMARY OF THE INVENTION Generally the device of this invention comprises inner and outer connecting means or coupling members which are adapted to be releasably connected to opposite sides of one or more holes in the side of a pipe casing to form either single or plural sealed ducts or passageways through and with such hole or holes. f

The outer connecting member comprises a fitting with one or more ducts therethrough, corresponding to the holes it is to cover, with internally threaded pipe connecting fittings at the outer end of these ducts and a concave curved cylindrical surface at the other end for fitting flush against the cylindrical outside of the casing around and `over the hole or holes therein. Surrounding the inner end of the one duct in this member there is provided a ring groove for seating and cementing in a resilient gasket or O-ring which O-ring then held against the outside of the casing around its hole by a U-bolt around the outside of the casing connected to ears or flanges on the outer member.4 If the casing and inner connecting member have two holes and ducts, respectively, one for suction and the other for pressure', there are provided two grooves in this inner member for such` gaskets. One groove is just around the suction duct and theother groove is around both the first groove and the other or pressure duct, so that the outer surrounding pressure gasket insures that any leaks in the connection of either duct will prevent contamination from anything external. Thus no welding or any special attachment is required between the well casing and the outer member. This is also true for the inner member so that all that needs to be provided is a casing with holes in the location at which the side connector is to be connected. f

The inner connecting member comprises one or more elbow ducts corresponding to the one or more holes in the side of the casing and outer connecting member. The outer or lower portion of the elbow duct or ducts parallel to the axis of the casing is provided with threaded fittings for the pipe or pipes to be suspended in the well casing, while the other end of the elbow duct or ducts is provided with a convex surface which fits flush against the inside cylindrical surface of the casing, and around and over the hole or holes therein. Surrounding this other end of the elbow duct or ducts. there is provided a ring grove for seating and cementing a resilient gasket or O-ring, which is then held against the inside ofthe casing, around and over the hole or holes therein by a screw applied clamping lever mounted on the inner member. This clamping lever, which has an end opposite the hole or holes in the casing, may be either a horizontally pivoted wedging type lever or a bell crank type lever. The end of the wedging type lever either wedges directly or through a roller while the end of the bell type lever positively pushes against the inside of the `casing to removably seal the gaskets that are on the inner member around, and the inner member over, the hole or holes in the casing. The lower end is operated to clamp the inner member in position by means of a vertical screw threaded into the inner member, which screw engages the other end of this lever. lf desired, the inner member may also be provided with a hook means at one of its other duct outlets for engaging the lower edge of one of the holes in the side of the casing for further alignment and support of the inner member therewith.

An inner member suspending means is attached such as by a pipe threaded into the top of the innler member surrounding the screw which operates the clamping lever, which suspending means may comprise a pipe cut to approximately the same length that the hole in the side of .the casing is below the top edge of the casing. At the other end of this suspension means is adjustably screwed a casing bridging bar which diametrically extends across the top of the casing and has notched ends that engage the top end of the casing to support the inner member and its depending pipe, pipes and/or pump. Once this suspending means is adjusted to length, it remains intact and in the well casing for easy removal and reset of the pipe, pipes and pump, whenever such is required or desired. Through the center of the suspending means there may be provided a hole for a tool for engaging the screw that operates the clamping lever on the inner member, which tool may be removed after the inner member is pressed into sealing tight engagement with the hole or holes in the casing.

A removable cap means may be provided for over the top of the casing, which cap may comprise one or two rings with gaskets in grooves which surround the casing. This cap for the single side duct casing connector `rnay be provided with an offset section into which may be screwed an electrical conduit for the electrical connection to the submersible pump in the well.

` Thus, it is an object of this invention to produce an efficient,

simple, effective, economic, rugged, protected, dependable` easily replaceable well casing side connector, which may be uncoupled and recoupled at frequent intervals after long periods of inattention as may be determined by sporadic service requirements, which connector requires no welding or special connections to the well casing and which also will comply with most local sanitation-codes.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS l. The Casing In FIGS. I, 2, 3, 5, 6, casings 8 there are shown portions of the

vertical well casing

10 and 12 for the embodiments of FIGS. 1 and 6, respectively, the former of which is provided with a single hole 14 in its side radially outwardly of the casing which is shown to be substantially belowthe surface l5 of the ground, while the casing I2 is provided with a pair of axially spaced holes 16 and I8 as shown in FIG. 6 for the two separate ducts of suction and pressure, respectively. The

top edge

17 or 19 of the casings 10 or l2, respectively, is preferably cut at right angles to the axis of the casing, and in the case ofa well, is shown to be horizontally flush for the support of the suspending means for the inner member as will be described later. f

II. The Outer Member In the embodiment shown in FIGS. l, 2 and 4, the outer member 20 has a single duct 22 therein, while in the embodiment shown in FIGS. 6 and 7 the outer member 30 has a pair of vertically spaced

ducts

32 and 34 which align respectively with the holes I6 and I8 in the casing 12. In the outside of each one of these

outer members

20 and 30 there may be provided, aligned with each of their ducts, an internally threaded pipe connection 2l, and 3l, 33 for the

ducts

22, 32, and 34, respectively, to which the

side connecting pipes

25, 35, and 35 are connected usually under the surface I5 of the ground.

The other ends of the

ducts

22, 32, 34 of the

outer member

20 and 30, respectively, which engagethe outside surface of the casings I0 and l2 around the

holes

14, and 16, 18 are preferably slightly concave to fit the contour ofthe outside of the casing as shown in FIG. 2. Surrounding this end of the

ducts

22 and 32 there are provided

circular grooves

26 and 36, respectively, into which may be placed and/or cemented resilient gaskets or O-

rings

27 and 37, respectively, as shown in FIGS. I and 6. In the case ofthe embodiment shown in FIG. 6, there is also provided a groove 38 which surrounds both the duct 32 with its groove 36 and the duct 34 as shown in FIG. 7. In this groove 38 there is provided a larger surrounding gasket 39 which seals both the pressure duct 34 and the gasket 37 for the suction duct 32 in event there may be any leakage in the gasket 37. This insures that only a positive pressure exists around this connection and thus prevents any contaminants from ever entering the system.

In order to insure that the

gaskets

27, 37, and 39 of the

outer members

20 and 30 are sealingly engaged with the outer surface oftheir casings l0 and l2-around the holes 14, and I6, 18, respectively, each of the

outer members

20 and 30 is provided with integral wing flanges 28 and 40 (see FIGS. 4 and 7), having apertures through which the leg ends of the U-bolts 29, 4l, and 42 may be inserted and tightened by means of nuts, such as nuts 45 shown in FIG. 2. Thus all that is needed to install the outer members in the two embodiments of this in vention is a wrench for tightening the nuts 45 on the U-bolts 29 and 4l, 42 to insure that the

gaskets

27 and 37. 39 sealingly engage the outer surface of the casings I0 and I2 around their holes I4, and 16, 18, respectively.

III. The Inner Member In FIGS. 1,2 and 5 there is shown a single elbow duct inner member 50 of the first embodiment having an elbow duct 52, and in FIGS. 6 and 8 a double elbow duct inner member 70 of the second embodiment having

elbow ducts

72 and 74. Each of these

elbow ducts

52 and 72, 74, has a lower end provided with internally threaded connections Sland 7I, 73 which are parallel with the axis of the casing, for the insertion of depending

pipes

55 and 75, 75", respectively. These depending

pipes

55 and 75, 75' extend down into the well and connect to either a submersible electric pump or a jet nozzle (not shown) respectively.

The other or horizontal ends of the

elbow ducts

52, and 72, 74, which align with the holes 14, and I6, 18, in the embodiments of FIGS. l and 6, respectively, are made in convex surfaces formcd on their respective inner members, as shown in FIG. 2 for the inner member 50, to fit against the cylindrical inside wall of the casing l0 or I2. Each of the surfaces around these duct ends is also provided with

internal grooves

56, and 76, 78, respectively, which surround the duct outlets, and which seat resilient gaskets such as

0rings

57, and 77, 79, the latter two of which may be joined to as a single double-apertured figure 8-shaped gasket (see FIG. 8).

If desired, as shown in FIG` 6, there also may be provided in one of the horizontal duct outlets of the

elbow ducts

52, 72 and 74, a hook means 59 whichirests on the bottom edge of its corresponding hole (herein hole 16) in the casing for further locating and supporting the

inner member

50 or 70 inside thc casing. However, such a hook means S9 is not necessary inv view of the adjustable suspending means to be described in the next section.

Outside the bend of the

elbow ducts

52, and 72, 74 and on the

inner members

50 and 70, respectively, there are provided horizontal pivot pins 60 and 80 for clamping

levers

62 and 82. The outer and lower ends 64 and 84, respectively, of these levers 62 and 82 (shown in FIGS. 1 and 6) releasably engage the inside of the casings I0 and I2 opposite their holes` I4, and

I6, 18. The lever 62 in FIG. l is substantially straight so that its outer end 64 wedges against the inside of the casing l0, and for this reason and in order to ease its release a roller 65 has been mounted thereon, however a shoe-shaped end (as shown in FIG. 2) also could be used without departing from the scope of this invention. The lever 82 in FIG. 6 is a bell crank levcr and its outer or lower end 84 pushes outwardly directly against the inside of the casing l2. It is to be understood that either type of lever can be used on either

inner member

50 or 70 without departing from the scope of this invention.

The other ends 66 and 86 of the clamping levers 62 and 82 are engaged by screws 68 and 88, respectively, threaded into the

upper boss portions

58 and 78, of the

inner members

50 and 70, which screws 68 and 88 may be operated by a removable tool as shown in FIG. 6. This tool 85 may have a notched end, or if a tube, its end may be flattened, to engage the flattened top 69 and 89, respectively, ofthe screws 68 and 88, for rotating these screws to force the clamping levers 62 and 82 into their positions shown in FIGS. l and 6 for compressing the

gaskets

57 and 77, 79 around their ducts and sealingly connect these ducts with their holes in the casings. This tool 85 also may be provided with a cross arm or handle 87 at its upper end for facilitating the rotation and removal of the tool 85.

IV. The Suspending Means There also may be provided in the

boss members

58 and 78 of the

inner members

50 and 70, respectively, threaded inserts which may surround the screws 68 and 88, into which

suspension pipes

90 and 100 may be threaded (see FIGS. I, 3, and 6, respectively). At the other or upper ends of each of these

suspension pipes

90 and 100 may be provided diametrically bridging

bars

92 and 102 which may be provided with opposite notched ends 94 and 104 that engage the

top surfaces

17 and 19 respectively of the

casings

10 and 12, and swingingly suspend the inner members S and 70 and their depending assembly of parts inside. their casings or wells. Each

bar

92 and 102 is provided with an aperture therein for the

pipes

90 and 100, in that it is through this pipe that the tool 85 is inserted and removed for clamping and unclamping the

inner members

50 and 70. The lengths of the

pipes

90 and 100 are correspondingly cut so that the distances between the

seats

94 and 104 and the alignment" of the

inner member ducts

52, and 72, 74 correspond exactly with the distances of the

holes

14 and 16, 18 from the

top edges

17 and 19 of the

casings

10 and 12. These lengths are determined and the

pipes

90 and 100 are then correspondingly cut and threaded before the

inner members

50 and 70` are installed. If further finer length adjustment is necessary, such may be provided by` the threaded ends of the pipes 90 andl 100 in the

inner member sockets

58 and 78 and bridgingsbars 92 and 102. However, a very exact adjustment is not required because the diameters of the

gaskets

57 and 77, 79 are larger than the diameters of the

holes

14 and 16, 18 in the

casings

10 and 12. Each bridging

bar

92 and 102 may be provided with an arrow 96 (see FIG. 3) at one of its ends to align with a similar mark (not shown) at the top of the casing 10 and 12'to'indicate where the

holes

14 and 16, 18 are located in the casings sides so that when the inner member and its assembly is replaced it will be in an operative position.

V. The Cap In order to close the open top endof the well casing l0 or 12 there are provided in the two embodiments of FIGS. 1 and 6 different types of caps 110 and 13,0, respectively.

Referring first to the cap 110 -for the single side duct connector embodiment in FIG. l, such is always employed with a submersible electric pump to which an electrical connection must be provided. It is through this cap 110 that such an electrical connection 112 is madefln this embodiment the whole cap assembly 110 may comprise a lower ring 114 `of L-shaped cross section providing an inner Vangular seat 116 in which may be placed a compressible gasket OrO-ring 117. Above this lower ring 114 there may be provided an oblong apertured plate 120 having a radially projecting portion 121 which plate 120 has a shouldered seat 122 around its periphery for a second gasket or O-ring 123. This plate 120 also may be provided with a second shouldered seat (not shown) for the gasket 117 which along may `sufficiently frictionally engage the casing to eliminate the necessity for the lower ring 114. The projecting portion 121 on theplate 120 has an aperture 125 through which a conduit 119 may be threadedly connected for conducting the electrical conductor 112 up inside the cap 110 and down through the well to one side of the bridging bar 92 to the submersible pump (not shown); The lower ring 114 may be clamped to theupper ring or plate 120 by means of bolts 115 to clamp the gasket 117 into sealing engagement with the outside circumference of the casing 10 and to hold the ring 114 and plate v120 vin place once they are installed. Over the top of the plate 120 and its extension 121 there may be an oblong shaped domed cover` 126 of the cap 110 which has an outwardly extending peripheral flange 128 with spaced apertures 129 therein for receiving bolts 127 that may threadedly engage and correspondingly align holes in the plate 120 and its extension 121 for clamping the O-ring 123 for sealing the cover or cap over the open end of the well casing. Thus when access to the innerV member 50 and the assembly connected thereto is required, all that is needed to be done is to remove the bolts 127 and cover 126, insert the tool 85 to loosen the screw 69 to release the lever 62, and then pull the whole inner assembly out of the well casing 10, which assembly includes the bridging bar 92, supporting or suspending pipe 90, the inner member 50, pipe- 55 and the submersible pump on the lower end thereof plus its electrical cable 112.

Referring now to the cap 130 shown in the embodiment of FIG. 6, there'is no electrical connection required because it is a two pipe system, and the pressure in one pipe 75' is used through a jet (not shown) in the lower part of the well to force the liquid up through the other or suction pipe 75. ln this instance a simpler cap 130 may be employed as shown, which may comprise a domed cover 136 having an enlarged open lower end 132 provided with a shoulder 134, which shoulder rests on the bar 102. This cover 136 may be provided with three equally angularly spaced set screws 137 which engage the outside of the casing 12 to removably hold it in place. lf

desired, the cap 130 may comprise the domed cover 136 and a single lower ring (not shown) such as ring 114 shown in FIG. l

which carries a gasket 117 for engagement with the lower end of the cover. In this case the domed cover 136 may be provided with a flange (not shown) for connecting the cover to the ring 114 as at 129 in FIG. l.

It is not always desirable to seal the

cap

110 or 130 to the top of the casing or 12, since such may prevent the operation of the pump in the bottom of the well by producing a vacuum in the casing. Therefore, it is desirable to allow the cap to breathe, either through a downwardly open crack 138 as shown in FIG. 6, through a bleeder holerin the cap( (not shown), or through the conduit 119 in FIG. 1 to an uncontaminated place as inside a dwelling where the electrical supply conductor 112 is connected.
