WATER WELL SCREEN Filed March 12, 1932 Fla. 1

INVENTOR.

ATTORNEY.

Patented Aug. 2, 1932 STATES ERVIN IA. KELLEY, OF KANSAS CITY, MISSOURI WATER WELL scREnN Application filed March 12, 1932. Serial No. 598,336.

My invention relates to improvements in a water well screen.

The object of my invention is to provide a sectionally arranged screen, separable with respect to the sections.

A further object of my invention is to provide a screen consisting of a plurality of sections having an annular wall and a plurality of seats spaced therearound as means to stack the sections in axial alignment.

A still further object of my invention is to provide a water well screen composed of a plurality of members having an annular funneled wall with a flange on the end thereof, and a plurality of lugs spaced therearound functioning as a'seat for the sections as stacked, and each lug having vertically aligned therewith a tongue, and means to connect the same with the corresponding lug portion of the adjacent section, each section being axially aligned and the adjacent upper and lower ends thereof being spaced apart and lapped to'provide ample inlet for the flow of water thru the opening.

A still further object of my invention is to provide a funneled section, each section having means to seat an adjacent section thereon concentrically, and means to attach 3 the sections so that the adjacent end portions will lap vertically but be spaced apart horizontally, the upper section lapping over the lower and on the outside thereof, so that a gravel filling when placed therearound will not be inclined to freely pass thru the opening to the interior of the screen, by which means the gravel functions as a filter and spacing means for the wall of the well from.

40 the screen which is axially positioned therein. These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of this specification, and in which like characters will apply to like parts in the different views, and in which V Fig. 1 is an elevation of the lower portion of a well partly in section showing the screen r with a gravel filling therearound and an outer casing partly pulled upward.

. Fig. 2 is an enlarged plan view of one of the'screen sections.

Fig. 3 is a sectional view taken on line 3-3 in Fig. 2', the said View showing two of the screen sections assembled. v

My invention herein disclosed consists of a funneled section comprising a side wall 1 having afiange A on the upper endthereof and a plurality of lugs 2 spaced therearound and integral therewith, each lug having a 9 bearing B on which the wall 1 will rest, and a shoulder G and'a tongue portion 1) downwardly extending and to seat on the offset above the shoulder C, and being secured thereto by a pin 3 engaging in an aperture in the tongue and the lug.

"A series of screen sections thus arranged will stack in axial alignment providing an opening as at E between the adjacent ends thereof, and the adjacent end portions will lap so that'gravel as shown at 4 will not freely pass therebetween while being filled to the upper extent as shown in Fig. 1. The gravel functions as acfilter against soil or fine sand F passing therethru withithe flow ofwater to the interior of the screen.

In assembling my screen structure, aplate 5 which is disc like in form is attached to the lower end of the bottom screen member so and being so arranged, a better footing is provided for the weight of the component parts of the well casing as a whole.

Secured to'the top member of the screen is a flange union 6 threadedly engaging on a casing 7 the casing extends to the surface or top of the well and in which is placed the suction pipe of a pump, the-latter not being shown in the drawing.

In Fig. 1 is shown a casing 8 employed while drilling a well, the said casing being lowered as the drill descends, and when the desired, quantity of water is encountered, the pipe 7 with our screen arrangement secured to the lower end thereof in the manner previously described is lowered into the wall. I then proceed to fill with gravel as shown in Fig. 1 and withdraw the casing 8 as the fill- I ing is made,the gravel being the supporting means for the'w'all should the same be m- 199 clined to cave or wash freely, and in all instances the gravel must extend upward the full length of the screen and further if so desired. The filling above the screen may be sand which of course is at the discretion of the workman installing the same.

It will be understood that the filling in contact with the screen will impose a pressure thereon, and to resist such I have arranged a flange member A as previously described integral with the smaller end of the section, the other end having its bearing on the lugs as at C, the said lugs being spaced apart and fitting snugly with the tongue portion of each succeeding section is reenforcing'means for the lower end thereof.

It is now readily seen how I am able to construct the funneled wall very thin which is the means to reduce excess weight and eX- pense in each section and the assembling of the screen.

Such modifications may be employed as lie within the scope of the appended claim, and having fully described my invention, what I claim as new and desire to secure by Letters Patent is In a water well screen, a member having an annular flanged funneled wall, the flange inwardly extending and integral with the small end of the funneled wall and functioning as a reenforcement therefor, and a seat for a flange union of a casing, lugs spaced around the funneled wall, the lugs transversely extending across the wall, each lug having a tongue longitudinally extending and aligned therewith, means to connect the tongue with the lug of an adjacent funneled wall, by which means the said walls are axially aligned and attached, substantially as shown.

In testimony whereof I afiiX my signature.

ERVIN L. KELLEY.
