'WELL GASNG.

.application 'filed october 29, 1926. Serial No. lt5,051.

, 'This invention contemplates the provision ot a Well casing designed to be used both in the capacityot a strainer and casing, and attorded maximum strength and percolating area, which will not corrode or become clogged as metal casings frequently do.

Another object ot the invention resides in the provision ot a Well casing, wherein the sections can be quickly and conveniently loW- ered into the Well, and supported in a manner which holds them in proper alignment, with the casing sections supported to prevent collapsing incident to the slipping ot the earth. f M

@ther objects and advantages ot the invention vvill be better understood when the following detail description is read in connection vvith the accompanying. drawings, the invention residing `in the construction, combination and arrangement ot parts as claimed.

ln the drawings forming part ot this application like numerals of reference indicate similar parts in the several views and `vvhereinz:

lligure l is a view in elevation and partly lligure 2 is a top plan vievv.. p l

Figure 3 is a view ot one ot the segments ot each section.

` lligure l is a sectional vievv on line lr-l or Figure l.

lligure 5 is a top plan view ot a modihed construction.

1ltigure 6 is a vievv taken at a right angle to lligure 5.

1llignre l is a vievv similar to Figure l showing each Well casing divided into tvvo sections.

lin accordance with the present invention, the Well casing is made up in sections adapted to be lovvered into the Well on suitable spaced guides, totaciliutate the building up casing, `with the guides further serving to hold the casin sections in true alignanol to atlord t e casing in its entirety manimum strength to minimize the possibility ot the casing collapsing by the slipping ot the earth or tor any other reason. ln the drawings lll represents the guides above mentioned which are channel-shaped in cross section as clearly illustrated in Figure 2, these guides being preferably in the nature olf ll' beams equidistantly spaced apart. ln Figures l and 2 l have shown tour ot such beaamt9 and each section ot the Well composed of four segments, each segment being of the construction illust-rated in lligure 3 and in dicated at ll. ln this hgure it will he noted that the opposed sides ot the section are reduced to Jorm a tongue l2 which slides in the channel formed by the adjacent side ot the ll beam 10. Consequently the component parts of each Well section can be conveniently lovvered into the Well and the partsgproperlyA aligned as above stated. ln Figures l and l it will be noted that each section or segment ot the well casing is constructed ,of concrete eov with spaced vertically disposed slots 13 i which are tapered as clearly illustrated in -Fig'ure t, being. tapered trom the er to the outer sides ot the section, which permits of Water or other liquid to seep through and enter the casing at a very slow velocity, and at the same time strain the duid to exclude sand or other foreign matter. By reason ot the tact that the sections are constructed ot concrete or the like the casing will not rust onoorrode, and the possibility .ot the openings being clogged is materially eliminated.

ln Figure 2 the casing as a vvliolefis ot the same construction as that shown in Figure d, except that the sections ll are porous to per mit the seepage or entrance ot Water or other liquid into the casing Without using slots 13.

ln Figures 5 and o each section ot" the Well casing is divided into halves and indicated at ll, in which instance only tvvo l beams/or the like l5, are used, and in this particular instance the sections are porous, although sections provided With slots ld may also be used in place thereof. lin lligure 7 l have shown substantially the same construction shown in Figure ti, wherein each section ot the casing is dividedinto halves indicated at lo and only tvvo ot the l beams l? employed. 'llhe sections in this view are provided with slots 13 in contradistinction to being vporous as in the case ot the section shovvn in Figures 5 and ti..

llt is to be further understood that the l beams or supports can be ot any desired length necessary tor the sate handling ot the sections as they are lowered into the vvell, and may be also ot any desired proportions to adord the necessary strength to the casing as an entirety and to maintain the sections in pertect alignment. Furthermore each vvell section may be made up ot any number ot desired segments or component parts similar to what is shovvn in Figure 3, and the diameter et the sections varied Without depart lill lll@

llfltti lll@ -limit myself to what is herein shown and described and that such changes maybe resorted to when desired as fall withinl the scope of what is claimed.v

What is claimed is: Y

1. In combination, a plurality of spaced vertically disposed channel-shaped guides, a well casing comprising a plurality of concrete sections, each section including segmental parts designed to be slid downwardly on said guides to a position for use, each of said segmental parts having vertically disposed slots tapered from the inner to the outer surface thereof, and said guides supporting said sections in proper alignment and affording the well casing proper strength and rigidity.

2. In combination, a plurality of spaced vertically disposed I beams, a well casing comprising a plurality of concrete sections having percolating areas, each section including a plurality of segmental parts, tongues Jformed on the opposite edges of each segmental part and forming shoulders adjacent thereto, said tongues being adapted to slide downwardly between the adjacent I beams with said shoulders contacting the edges of said beams to aord the well casing proper strength and rigidity.

In testimony whereoI affix my signature.
