WELL.

Application filed October 22, 1921.

To all 'whom t may concern Be it known that I, DARNEY H. MAURY, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wells, of which the following is a specification.

This invention relates to incased wells of the general type comprising an inlet terminal and a superposed casing separated by a water-tight bulkhead, said well casing forming a dry well pit and being of sufficiently large diameter to permit the installation on the floor thereof, formed by said bulkhead, of pumping units large enough to be of an efficient type, and so located as to be at all times accessible in place for purposes of inspection and repair. 1

Wells of the type specified are commonly sunk by means of clam-shell or orange-peel buckets.

' A principal object of the invention is to provide a well of the general type specified, theinlet terminal of which may be sunk and the bulkhead separating the inlet terminal and well pit installed, without removing or expelling the water from the well casing.

As it relates to an inlet terminal which may be sunk without pumping or otherwise removing or expelling the water from the well casing,rI attain the object of the invention by means of'a new and novel form of inlet terminal which I have devised, which may be built complete before being sunk, and sunk as a finished unit ready for use.

As it relates to the installation of the bulkhead without removing the water from the well casing, I attain the object of the invention by a novel bulkhead construction,

comprising beams which extend across the well easing at the upper end of the inlet terminal, the ends of said beams resting upon seats formed in the inner sides of said well casing, and secured tol the under side of said beams are plank, or the like, which close the upper end of the inlet terminal and also form a platform on which the bed of con? crete which forms the bulkhead proper is deposited, .whereby said beams will become embedded in the concrete forming said bulk` head and will impart necessary strength thereto to carry the weight of the pumps and other parts supported thereby.

The platform formed by the plank secured to said beams also provides convenient support for setting thesuction pipe or pipes for Specification of Letters Patent.

complete in advance and sunk to position in the well casing after sinking of the well casing has been completed.

An inlet terminal adapted for the practice of my present invention also comprises the various features and details of construction hereinafter described and claimed.

In the accompanying drawings, in which my invention is fully illustrated,

Figure 1 is a vertical, sectional view on the line 1 1 of Fig. 2, of the inlet terminal and a portion of the superposed well casing of a well embodying my invention.

Figure 2 is a sectional top plan view of the well, the section being substantially on the line 2 2 of Fig. 1.

Figure 3 is an enlarged, skeleton section on the line 3 3 of Fig. 4, all concrete portions thereof and the filtering material being removed.

Figure 4 is a horizontal section. on the 1in 4 4 of Fig. 3; and

Figure 5 is a top plan View of the finished well showing pumps installed.

For purposes of definite and concrete illustration, I have, in the drawings, shown my invention and improvements as embodied in a well the well casing of which. including the supports for the inletv terminal, are made of concrete. The form of well shown is, however, merely typical, exemplifying a preferred embodiment of my invention, and I do not, therefore, desire to limit my invention to use in wells of the particular construction shown, as persons familiar with interior of the well casing, as a whole, Said well casing and bulkhead being water-tight, thus preventing access of water to the interior of the well casing, which, when pumped out, will form a dry pump (pit, of

which said bulkhead forms the floor, said i well casing being of such large diameter that a pumping unit or units, indicated at D, may be installed on the floor thereof and will be accessible Afor purposes of inspection and repairs without removing the same from said well casing.

A further advantage of a well embodying my invention is that the pumping units can be located below the normal ground water level, thus eliminating the necessity for priming said pumps, as well as overcoming other difficulties incident to operatingy pumps under suction lift.

Also, owing to the large diameter of the,

well casing and inlet terminal,the well may be sunk by means of a clam-shell or orangepeel bucket.

To eect the object of the invention as it relates to a novel form of inlet terminal which may be built complete before being sunk, and sunk as a finished unit ready' for use, said inlet terminal C comprises upright concrete supports l which extend from the bottom to the top of the inlet terminal and are shaped to define openings 2 in the sides of said inlet terminal through which water may How into the same. At the outer side of the inlet terminal, the openings 2 are desirably of such large area that the inflow of water through the stratum adjacent to the outer side of the inlet terminal will be of such low velocity that practically none of the finer vparticles of sand in" said stratum will be drawn into the inlet terminal by said inflowing current of water. The areaof the o enings at the inner side of the inlet terminal) can be made relatively much smaller than the area of said openings at the outer side of the inlet terminal without causing appreciable friction losses, and this will enable the concrete supports 1 of the inlet terminal to be made suiiiciently large to render said supports strong enough to `sustain the' stress to which they will be subjected in'sinking thewell, without breaking.

`As shown, the si` es of said supports l converge inwardly at substantially uniform angles.

Secured to the inner and outer sides, respectively, of the openings 2, are

strainer plates

3 and 4.

The strainer plates 3 secured in the inner sides of said openings, are preferably made of thick durable metal, a desirable thickness in practice being about one-half an inch.

The portions of said plates exposed between the upright supports l are perforated, a desirable size of perforations in most cases being labout an inch in diameter.

ln like manner, the portions of the strainer plates 4 exposed between the upright supports l are also perforated, a desirable size for said perforations, in most cases, being about two inches in diameter.

As shown, also, the outer strainer plates 4 masses extend entirely around the circumference of the inlet terminal, forming a sheet metal jacket therefor. ln accordance with usual practice, said strainer plates comprise separate sections bent to the radius of the /outer surface of the inlet terminal, the edges of which are connected by butt straps which overlap and are secured to the inner edges of adjacent plates, so that the outer surface of the jacket formed thereby will present a continuous, smooth and unobstructive surface, thereby facilitating sinking of said inlet terminal.

The bottoms of the openings 2 in the inlet I terminal are closed by a concrete ring 5 formed integral with the upright supports l of said inlet terminal, the bottom side of said ring being outwardly and downwardly v The upright supports l and the bottom.

ring 5 of the inlet terminal are, respectively, reinforced and strengthened by reinforcing bars 7 and 8 in a familiar manner.

With the described construction it is obvious that the openings 2 in the sides of the inlet terminal will form pockets, the lateral sides of which are closed by the upright concrete supports 1, the innerand outer sides by the

strainer plates

3 and 4 and the bottoms thereof by the concrete bottom ring 5.

The inlet terminal having been otherwise finished, the pockets formed by the openings 2 are filled with filtering material 9, consisting of gravel, crushed stone, or the like, which is graded from relatively coarse material adjacent to the inner strainer plates 3 to relatively fine material adjacent to the outer strainer plates 4. To prevent loss of the relatively fine filtering material which rests in contact with the outer strainer plates 4, through the perfor'ations therein during the process of sinking, the inner surfaces of said strainer plates are lined with thin material l0 provided with small open- ,j

reread lining '10 :Sjefmed 0. the, infner :iside sides of the 4molds Afor the, upright concrete ,supports ,1 are :secured to the inner side of the vjacket formed bythe strainer plates 4 in proper position` andthe outer edges -off Vsaid yplates 11 connected 'pairs to opposite edges of the' inner strainer plates, 3, which,

being relatively thick and strong, will form a rigid support for said plates 11.

The lnner sides, not shown, of the molds for forming the upright supports 1 and the bottom ring 5 are made of wood removably and temporarily secured in position, convenient means for securing the inner mold plates for the upright supports 'consisting in boltingl the edges thereof to the inner strainer plates 3, while the removable inner wall for the bottom ring 5 may be bolted to tie bars 12 the ends of which are connected to the lower edges of the inner strainer plates 3 and to the flanged support 6 for said bottom ring 5.

Also, to prevent bulging of the mold plates 11 under the weight of the concrete poured into the molds to form said upright supports, said plates are connected at intervals between their ends b-y tie bars 13. As shown, the plates 11 at opposite sides of each mold are thus connected by two tie bars spaced vertically.

After the inlet terminal has been finished and the pockets formed by the openings 2 therein have been filled with filtering material, the upper ends of said pockets are closed by suitable coverings, indicated at 14, preferably made of wood and which rest upon the bridge the spaces between the upper ends of the upright supports 1 of said inlet terminal and form supports on which the concrete for forming the superposed well casing A is deposited.

As the well is sunk, the superposed well casing A is extended upwardly, the mold therefor preferably consisting of a sheet metal outer shell 15 and a removable inner form, not shown, preferably made of wood or other suitable material. The outer shell 15 of said mold is preferably built up from metal plates and is designed to form a permanent jacket for the well casing A, thus providing a smooth outer surface for said well casing which will facilitate sinking of the well. Said metal jacket also tends to insure the watertightness of the well casing.

Directly above the inlet terminal, the well casing A is provided, on its inner 4surface,

with a seat for the bulkhead C, said seat being preferably formed by recessing the inner surface of the well casing A, as shown at 16, said recess forming shoulders 17 and 18 between which the edges of said bulkhead will be confined.

k"tIhe inletterminall 'well casing A having been fiiished, the bulkhead` C visfl'i'eiixt 'installejd,` the construction rand the manner of linstalling lthe same l'beint'g as.follow's' l ySaid `bulkhead comprises beams 19, which extend across thelwell casing and vthe ends 4of which rest upongihe ,seat ferme-1 in .the inner surface of the well` casingby the shoulder 18 at.- the lowe'rjgside of the-recessl l16 and .secured rto, 'the 1under Iside, lof`s"aid beams are plank 20, which 'close the top of the inlet terminal and alsoform a support lon which the concrete for the. body'p'ortion 21 of said bulkhead is deposited.

In practice, the portion of said bulkhead C consisting of the beams 19.and platform 20 will be built and fitted to the upper. end of the inlet terminal assoon=as the shoulder 18 at the lower side of the recess 16 is formed, said platform vbeing thenf' removed and the erection of the well casing A con-f tinued. f

As desired attachments to the bulkhead C, a suction pipe or pipes 22 for the pum or pumps D, a test pipe 23 and, if desire a manhole 24 adapted to provide access tol the inlet terminal C, may conveniently be set in proper position by securing them to the platform 20 after said platform has been finished.

The well casing having'been finished and sunk to the full depth contemplated, the platform 2() with any attachments thereto,

is lowered to position, with the ends of the V beams 19 resting upon the seat formed by the shoulder 18, the edges of said platform 2O being preferably bevelled, as shown at 25,' to facilitate engaging said platform with the open upper end of the inlet terminal. Also, to close any space 'which may exist between the edges of said platform and the wall ofthe inlet terminal, batten plates 26 are secured to the top of the platform 2O which project outwardly and rest upon the shoulder 18.

The platform 20 having been set, the concrete portion 21 of the bulkhead is laid thereon, great care being exercised in depositing said lconcrete in order that segregation of the constituents of the concrete shall not occur. 1

The concrete portion of said bulkhead having been laid, a top dressing of neat cement grout is preferably applied thereto under a head of water in the well casing to subject said cement grout to suflicient presstrengthening said bulkhead.

vAfter the concrete portion of the bulkhead Chas hardened sufficiently the water is pumped yout of the well casing, which will then form a dry pit on the iloor of Which k-formed by said bulkhead-the 'pump or pumpsv Dinay be installed andv connection made to thesuction pipe orpipes 22. With the described construction, it is obvious that said pumps and associated parts and apparatus will be readily accessible for all purposes.
