(ci.'io`3''5 9 Claims.

This invention relates to water systems and has special reference to pump water systems using the so-called jet type pumps.

There has long been aneed felt, on the part of people who depend on wells for `their water supply, for a sanitary and eiricient as well as an inexpensive water system which will give the country home the same convenience as the city home. However, many State boards of health, realizing the dangersrof-contamination of wells which are too close to buildings, have specified that no well shall be placed within-a prescribed distance from a building. This one' stipulation on the part of sanitation officials has caused a great diiiculty to well users, as until comparatively recently, pumpshad `to be located directly over the well, and this required a special well or pump house to keep thepump from freezing, etc., and of course increased the cost ofthe water system, and still the water was notin the home. Various means were developed to bring the water from the well or pump house to the home and other buildings, but such means were nctsanitary.

With the introduction of. the so-called jet pump, means was developed whereby the pump could be placed in offset relationA to the Well,l that is, in some other location other than directly over the well. Still, there were oilcial objections to installing jet pumps in the house, as one of the lines of a jet system is a pressure line, while the other is a suction line, at least for certain periods during the operation of the pump, and an exposed suction line can easily be the cause of a contaminated water supply.

In addition, in order to install a jet pump in offset relation to a-wellgand permit easy access to the well, a pit must be provided over the well so that all water lines will be below `the frost line. This pit often causes contamination, especially if heavy rains fall, or in flood conditions.

A well water system whichA canv meet the rigid requirements and be completely-satisfactory has not heretofore been known.

It is my principalobject'to fulfill the long felt need for an efficient andl convenient, sanitary well water system.

Another object is toa provide fai Vwell water system wherein the pumpf may be placedl ini ones home and which, wliilerprovidin'g; theutmos't in sanitation,` is comparatively less expensive" t'o in* stall and less expensive to lmain-tain#than fhereto# fore known systems.-

Another object is to provide novel means for transferring water between the well casing and the pump so thatthere will' be no danger of pollu' tion.

Another object is ftoeliminate thejneed for a pump house,Y as wellasthe s o-ycalled pit used with theoiset pump installation.

'Another object isgto providea novel water distributor for directing waterA to and from the wellvcasing.

Another object is tov provide anunderground discharge head whichiorI-nsl a part of the well casing, Yand 'which `prc\ ri d e s means, in conjunction with the water distributor, for transfer of water between external water lines and the casing of the'well.

Another object is to l provide means for sealing individual water lines from each other as they are transferred in closely adjacent position `between awell casing-and a pump which is placed in oiTsetv relationgto the well casing.

VAnother object is to-provide means forservicing the components ofv awell Water system which are contained.-` inthewell casi-ng without'manually breaking any'of-the connections inthe water SYStemo 4 4 These and-other objects'and `advantages will become more apparent'as'r the descriptionof the invention-proceeds.

Fig, 6 isa/broken sidi-: 1 revauoai view' of a double-pipe jetpiiip" installed iniaccor'darlcev with my invention.

The common method of; installin'ga jet type pump'in oiset relation to the well isfto use a so called pit which extends below'the vfrost line, and then.' use common `90 elbows to connect the twohorizontal lines to the 'vertical linesV at the upper end of the casing. The pit isrequired to permit access to the well, and the elbow connections, in the event repairs must be made. At

present a pit is required if access is desired in either a single or a double pipe jet installation.

In the drawing, the reference numeral I indicates sections of a well casing, usually iron pipe of suitable diameter, and obviously, the casing will extend above the surface of the earth for sanitary reasons.

In order to omit the usual pit which is used in installing jet type pumps in offset relation to a well, I have provided a discharge head 2 which is installed between two sections of the well casing just below the frost line and forms a part thereof, the discharge head 2 having a bore of substantially the same size as the casing. The head 2 has a lateral projection 3 thereon which provides a connection 4 for the water pipe 5, and also provides a passage 6 for water to pass from the pipe 5 into the casing through the hole l in the wall 8 of the discharge head 2, the hole 'I preferably being in off-set prelation to the connection 4 as shown.

On the inner wall 8 of the head 2 a boss or connection 9 is provided, preferably axially of the connection 4 as shown, to which the water pipe I is attached, there being a hole II through the wall 8 of the head to permit the now of water between the pipe I0 and the inside of the well casing, and the pipe ID' being carried within the pipe 5.

Jet type pumps require two separate water lines, thus the pipes and I0 are provided. The respective connections of the pipes 5 and I0 to the casing of the well are permanent in my improved water system, and no pit need be provided to permit access to same, the pipes, once installed, may be buried and forgotten as they will last as long as the well casing without need of attention.

The two water lines of a jet type pump may be referred to as a pressure line and a delivery line, and in the operation of a jet type pump l, the latter forces water from the pump through the pressure line down into the well and discharges it upwardly from'a jet'Y nozzle in-the jet fitting 'II into the `delivery line. This jet discharge causes a suction and draws additional water from the well into the delivery line and back to the pump where some of the water is taken off into a storage tank while the remainder is pumped back through the pressure line and through the jet nozzle to draw up more water from the well. This operation, of course, is well known to those skilled in the art.

Of the two lines I have thus far mentioned, the pipe 5 is a part of the pressure line, and the pipe IG is a part of the delivery line. As means to connect the lines 5 and I Il to the pump, which is located at a laterally remote location from the well casing, the lines 5 and III may be ext-ended to the desired point away from the well, for example, into ones basement, and an elbow, I2 and I3 respectively (see Fig. 4), is provided t0 direct each of the lines 5 and IU upwardly to a suitable level for the pump, which, according to most regulations, must be above ground level. Vertical pipes I4 and I5 respectively are provided to extend the pressure and delivery lines to the desired vertical level for the pump, and any suitable adapter, such as rthe one I5, may be provldedto seal the end of the pipe I4, provide a connection I'I for the pipe I8 whichis connected to the pressure line of the pump, and to permit the pipe I5 to extendfrom the pipe I4 so that it may be connected to the delivery line of the pump.

Thus far, we have a pressure line, which we will designate as the line A, leading between the pump and the well casing, and a delivery line, designated B, leading between the pump and the well casing, both lines having an opening into the interior of the casing.

Within the casing two separate lines are maintained, by means of the pipes I9 and 25, the pipes 'being also marked C and D respectively to denote the pressure and delivery lines respectively within the casing. The pipes I9 and 25 extend down through the casing and into the well water, and the usual jet fitting is connected to the lower end of the pipes, as will be apparent to one skilled in the art.

In order to connect the water lines A and B with the lines C and D respectively, I have provided a water distributor which is removably carried in the well casing and is shown installed within the bore of the discharge head opposite :the openings 'I and II which form a part of the lines A and B respectively. The water distributor provides means for connecting the pressure line A to the pressure line C; and the delivery line B to the delivery line D without mixing the water of the pressure and delivery lines.

The water distributor has longitudina1 internal water passages 2l and 22 to which the pipes I9 and 2E) respectively are connected, the passages being separated by a wall 23, preferably as shown. An opening 25 is provided through the wa-ter distributor from the passage 2l into the well casing, preferably opposite the opening 'I in the discharge head, and a second opening 25 is provided through the `distributor from the passage 22 into the well casing, preferably opposite the opening II in the discharge head. (More than one opening 25 is shown here as more than one may be employed if desired, and of course the same is true of the hole 24.)

In order to seal the water of the pressure line A--C from the delivery line B-D, :and to prevent loss of water into the well casing as it travels in the pressure and delivery lines, I employ a plurality of seals carried on the outer face of the distributor and preferably 0f leather whereby water will swell them and provide a better seal. The seals 25 and 21 are carried on the distributor on opposite sides of the opening 24 through the distributor, and are of cup-like form with the free edges thereof facing towards each other, and, of course, towards the pressure of the water in the line A-C.

The water distributor is suspended in thewell casing so that the seals 25 and 2 are disposed on opposite sides of the opening 'I in the casing through the wall 8 of the discharge head. Thus, it will be seen, that water, traveling in the4 pressure line A-C from the pump down into th-e well to the jet nozzle, will enter the casing through the hole v1, and the seals 26 and 21 will prevent the water from going anywhere but through the hole 24 and into the water distributor passage 2 I, which forms a part of the pressure line A-C, and down through the pipe I9 to the jet nozzle in the well. Y

The preferred means for supporting the water distributor so that the seals 26 and'2'l are disposed on each side of the opening 1 in the casing, is similar to that illustrated in my U. S. Patent No. 2,230,856 of February 4, 1941 wherein the well casing is shown extending above the ground leveland the cap-like member (18 in the patent) is carried on the ,upper end of the casing and has attached thereto a suspending pipe section 2s 5 in the patent) which in turn is attached to the water distributor, the length of the pipe 28 determining the position or depth at which the waterdistributor is held inthe well casing. Any suitable flat plate with a rubber seal may be secured on the upper face of the cap-like member shown in the patent to seal the upper end of the casing and thus prevent contamination of the well.

The water distributor also is provided with seals 29, 39, and 3| above the hole 25 which leads through the distributor into the passage 22, the seals being similar in construction to those previously described. However, the seal 29 has its free edge disposed away from the `hole 25. The reason for this is that at times, at least, .during the operation of a jet type pump, thereis suction present in the delivery line B-D, and `at such times as suction .is present, the seal 29, and of course the seal 21 on the lower side of `the hole 25, prevent the suction pressure from operating anywhere but on the delivery line B-D as the seals 21 and 29 are drawn inwardly toward the hole 25 and this augmente Athe sealof the delivery line.

It will be noted that the seal 21 is acted on by the pressure in the line A-C as well as by the suction 'which may be present in the line B--D, and that the seal 21 will effectively insure separate flowage of water in the pressure and delivery lines.

At times during the operation of a jet type pump there also may be pressure in the delivery line, and the seals 33 and 3l are provided to prevent any loss of water into the casing above the distributor from the delivery line, the free edge of the seals being faced toward the hole 25 so that any water under pressure trying to pass into the casing above the distributor may well pass the seal 29, but will merely force the seals 39 and 3l into more rm engagement with the walls of the casing and no appreciable amount of water will get above the seals 3U and 3|. Any water getting above the seals 39 and 3l will be -drained back into the well by means of the drain 32 provided in the discharge head.

The pressure which may vdevelop in the 'delivery line of a jet type water system obviously will not be as high as that in the pressure line as the latter is the drive line of they system, and thus the seal 21 will be kept tightly against the wall of the casing and the pressure and delivery lines will be effectively sealed from each other. It is deemed apparent that more or duplicate seals may be provided on the water distributor if desired, however, they are not deemed necessary.

The water distributor as here shown comprises a body portion having three main sections, an upper section 33 to which the pipe 28 for suspending the distributor is attached, a central joining section 3d connected to the upper section, and a lower section 35 carried by the joining section and to which the pipes I9 and 29 are secured for suspension in the well casing.

rihe lower section 35 has its outer end enlarged somewhat to provide ample room for connections for the pipes i3 and 20, and also to provide a radial shoulder or seat 36 for the seal 26. A

spacer sleeve 31 is installed on the'lower section F to space the seal 21 from the seal 25 `so that the seals straddle the hole 1 in the casing, there being an opening in the spacer sleeve to correspond with the hole 24 in the distributor and` permit the passage of water into the passage 2l. The

sea1 21 is carried on the upper end of the sleeve 31 and the joining section 34 is screwthreadedly installed on the lower section to hold the seals 26 and 21 and the sleeve 31 in place.

The upper section 33 has a threaded socket at its upper end into which the pipe 28 is `screwed to support the distributor, and a radial flange 38 which forms a seat for the seal 3|. A relatively short spacer ring 39 separates the seals `311i and 3 l, and a longer spacer sleeve 40 separates the seals 30 and 29. As shown, the upper section 33 is screwed into the joining section 34 to complete the distributor and hold the seals 29, 39, and 3l in place as well as their spacers.

It will be noted that the structure above described will permit safe andsanitary installation of a jet type pump in almost any location as the danger of contaminating the water system fdue to any defects in installation are, .for all practical purposes, eliminated, to wit:

There is no danger of `contamination during :doods or heavy rains as the Well casing extends above the ground, `and in addition is sealed tightly by means of a cap, not shown but described inthe above, so that no surface water can get into the well casing. There is no pit to collect surface water.

There is no danger of contamination in the water lines leading between the casing and the pump as the outside line, which is exposed and would be the one to receive any foreign substance that might cause contamination, is a pressure line, that is, water in the line is under ,constant pressure,'and should a leak develop in the pipe, water would be forced out of the line rather than anything being able to enter the line.

The internal line, which at times is a suction line, is carried within the pressure line and if any leal; develops in the inside pipe, the only thing that could enter same is good well water from the pressure line and there would be no danger of contamination therefrom.

The place where the pump is connected to the pressure and delivery lines is above ground level where there is no chance of contamination from outside due to foreign matter engaging the pipe lines.

A further convenience `provided by my above described water system is that in the event that anything goes wrong with the parts in the well casing, for example, if the jet nozzle should become worn or plugged, the entire mechanism can be lifted up from the upper end of the casing and removed from the casing without disturbing the pump or the water lines between the pump and the casing, and any repairs may be made. The entire mechanism may be put back into the casing, also, without disturbing the pump or water lines between the pump Iand the casing. By having a predetermined length for the pipe 23, the water distributor will be located in its proper setting so that the seals thereon separate the water of the pressure and `delivery lines :as above set forth.

It is deemed apparent from the foregoing description that the water flowing from the pump in the pressure pipe 5 will `pass into the pass-age t, through the hole 1, and into the casing. The water will surround the water distributor within the well casing intermediate of the seals V2t and 21, and the latter will prevent any loss-or leakage or water or pressure. There being .an opening 24 into the distributor, the water can only pas-s through the opening yand down into the Well through the passage 2l and pipe I9.

delivery line will enter ythe passage 22 inthe distributor from the pipe 20, and pass through the`hole, or holes 25 into' the space between the casing and -the distributor. The seals, 27, 29, 30 and 3| prevent any loss of water in the'delivery line at this point, and water can only pass through the hole I I into the pipe I and go back to the pump.- Y

In Fig. I have shown a modified form of discharge head and a water distributor installed therein for use with a so-calledsingle pipe or packer typefjet pump installation. The single pipe installation is used in small size Well casings from labout three inches and under in diameter, and in this system, the space between the inner wall of the VWell casing and the outer wall of the single pipe within the casing is used as one of the water lines.`

The discharge head 4I differs from the discharge head 2 only in that the drain passage 32 is omitted. There is a lateral projection 42 similar tothe one 3 with a connection 43 for the pipe 5,'and `a passage 44 and -a hole 45 to correspond with those of the head 2. There is also a boss 46 and a hole 41 in which the pipe I Il is connected as previously described. As in the two pipe system, the pipe 5 forms a part of the pressure line A, as does the passage 44 and opening 45.

The water distributor for the single pipe system provides for separate passage of Water in the pressure and delivery lines. In this instance, the pressure line is the same as in the two pipe system through the point where the water enters the casing, and the space 48 within the casing around the pipe 49 forms the continu-ation of the pressure line down into the well. The single pipe jet fitting which is carried at the lower end of the pipe 49 has seals which eng-age the walls of the casing and prevent water from going directly into the well and insure its being directed through the jet nozzle and into the delivery line 49, as is well known in the art.

The Water distributor has a seal 50 at the lower end thereof which corresponds to the seal 21 shown in Fig. 1, and which insures the water traveling down the pressure line below the seal. The pipe 49 of the delivery line is connected to the lower end of 4the water distributor and connects with the interior passage 5I thereoflOpenings 52 are provided through the walls of the distributor to permit water to flow intermediate the distributor body and the casing opposite the opening 4l in the casing in which the pipe I0 is connected. Thus the pressure line A-C and delivery line B-D are operatively connected. Seals 53, 54, :and 55, corresponding to seals 29, 3l) and 3I, are provided on the distributor above the opening 47 and operate as in the two pipe system.

The seals 50 and 53 are disposed on opposite sides of the opening 41 in the casing to seal the delivery line from the pressure line as in the two pipe system.

The drain 32 is omitted in the single pipe system in order to insure the seal of the water within the space 48, it being deemed obvious that were a drain provided Water would be forced upwardly therethrough and into the casing above the distributor, which would not be desirable as the water above the distributor would be above the frost line and Would probably freeze during cold weather and cause damage. The seals provided on the distributor are suicient to prevent any Water from getting above the distributor.

The, water distributor for the single pipe system comprises a body portion having an upper section 56 which connects tothe pipe 28 for suspending the distributor, pipe .'49, and jet fitting in the casing; a joining member or section 51 carried at the lowerend of the uppersection, Iand a lower section 58'carried by the joining section, and to which the pipe 49 is connected, preferably as shown. Y

A seat 59 is provided for the seal 59 on the section 58, and the joining section 51 holds the seal 5l) in place. The upper section, which is connected to the pipe 28, provides a seat 60 for 'the seal 55, and spacer sleeves 6I and 62 separate the seals 54 and 53. The joiningsection holds the seals .53, 54, and 55, aswell as their spacer rings, in place when the upper section is threadedly installed therein as shown.

The single. pipe system just described has all the desirable attributes of the double pipe system previously described, and it is deemed apparent that my invention will provide a sanitary andeiicient, modern water system for those who depend upon wells for their water supply.

It is deemed apparent that the distributor in all cases provides a wall to maintain the separation of the pressure line from the delivery line.

While I have here shown and described the presently preferred forms of my invention, it is deemed apparent that other modifications may be made which are within the scope ofthe appended claims.
