To aZZ fw/"wmt't may concern f Beit known that li,- riuonr I?. Soiiirrnnn, a citizen of the United States, residing ut- Poag, in the county of Madison and State of Illinois, have invented u nev.7 end useful Sand-veil Casing and Apperatus for Sinking the Same, of Which the following is e specification. .Y

The present invention relates to improveniente in e send Well casing and enV :ip- 'peratus i'or sinking or placing the seine ithin the grounoh the .seid casing being constructed of @plurality oit' porous sections, cylindricel in cross section, the lower sec; tionY which is pro-vided with n cutting edge or snnulur cutter, While the sections are connected in steycd reletioii to 'provide e stiii column to he ectueted hy,A en eppurel tus, e p .ortioiro which is sunlr Within end held heloiv the surface oi the gro-und fiecentto the exterior of the casing to lie sunk, und provided with ineens for forcing:

the column containing the cutter with the.

simuler cutter downwardly within the ground, the'cuttei.' being left in the ground with the casing when the Well casing has heen -sunlr the desired depth..

In a oriner application which resulted in letent o. 1,001,085' grjnted August 5 191i, an outer motel casing was prowie.;

vided for cutting the desired excavation in'-V the ground, endl a porous' casing was interposed therewithin, after which the instel casing Weswithdrawn, While inthe present invention'it vis intended that e porous casi ing-in the 'irst place shall -be driven or sunken similar to the 'metal cesing es in vthe aforementionedpatent, end he left-in the ground to constitute'. the Wells' of the Well.

' lt his been found by experimenting that the sections when properly loreced4 longitudinally und' held relatively toget er muy be driven or sunken 'by e jack act-ua ed pref-1 sure device so lthat the. cutting edge thereof will he projected through the ground or body' of send to the desired Waiter strate, end in cases Where sections have to be added thereto, it is simply necessery to remove thesinking apparatus and attach tothe upper end of the column the desired .num-

berof sections.

With the foregoing end 'other objects in View which swill eppeer es the description proceeds, the invention resides ip. the comthe details of construction hereinafter described and. cloirnedi it being; understood that changes in the precise embodiment of invention herein disclosed celibe vinode Withim in the scope ci 'what is cleir'ied without departing from theispirit oi' the invention.

The ditch ris then refilled with eertln the lowerinost section 5cl' 1the porousgvell ed casing'heing disposed Within-the pit prior to the iilling oit they eenth therein so that the Iiieteriel removedfii'ohi the pit Willsurround' i the lower .section 5 of the Wel-leasing und i oe pitched tight-ly thereohout and upon the e5 J7"hase fi. By this ineens the horse i is prop-l erly anchored so that the longitudinal. rods 6 which' erezconnected to the ,said hose Lland its braces 3 may extend upwardly shove the surface of the ground end have their upper to ends connected to the frame 7 to the underside o which et the desired corners there of ere connected the movable members 8 of the jack screws 9 the pivotafi pin l0, of the respective jacks, being connected to e frame 'i5 llwvhich rests upon the annular ring oi;-

plate 12 restingr uuon .the upper edge of the upper porous section .i3 of the Well casing. The ringV or plate l2 is ot sufficient Width to project slightly .within the 'more of im? the tuouig'es viewed inflg. l, and has connected thereto and extending' longitudinally downwardly therefrom within 'the bore ontv the sectionsof'thc Well casing, e series of binding, retaining or tieirods 14, the lowjer i051 are held relatively to each other and form e M0 rigid column. Carried, by the rinif or dish bination and arrangement of perte end in i5 of the iovver section. is e ileiige ring; il

disk l5 disposed to lit closely .upon

whose depending` flange 18 is connected inl infl'he above mentioned paient. ln the presterinediele of the ends of ille cylindrical bund 19, whose lower end 20 forms an annular outwerdlyluring cutter 21, the same being' so disposed the@` when ille jacks are operated to exert a` force against the upper freine 7 and downwardly upon the frame ll, the secrions of the well Casing are driven downwardly, lille utter oui'zing into lie sot-fl, gromid or sand sind thereby providing en annuler space for the reception ol die wall of the casing the seine is sunken.

The rode le prevent die seeions from oeing disploeed relatively to each other, in case of a eetling of the surrounding or base sand'. During elle insertion of the easing, lie sund at the cutter end within the casing' ik; removed as the easing is sunk, so that by *die time lille easing; is eoinpleely placed, no sund will be within ille seine. The lower ringr l5, projecting allnulerly within tile bore of -tl'ie porous Casing provides e ineens to receive a disk 22, which may be of merel or a porous material, and thus form a bot torn for the casing to exclude send that might enter from below the easing.

lroru the 'loregoing description taken in connection will; the drawings, it is e vident that by constructing a well Casing of a series of hollow porous sections held relatively thereto ro forni :i rigid Column during' the sinking operar-ion, lli-dt the seme may be driven wnii ille apparatus herein shown and described5 to lle desired depth and in e similar manner to the metal easing us shown ent ease, however, a porous lining constitutes the earth holding means and is lef therein to constitute the porous walls of the cylindrical shaped well. This present in- A vention also permis the leaving of the casing within the ground and does not necess tare lie pulling of the metal lining from around a porous casing es in the parent aforenient on ed.

A well easing of the class described, composed of a plurali@Y of porous cylindrical Seolions, a band secured to the lower section thereof, an amr-ler cuter carried by said band and projeeting below i a ring mounted upon *ih upper section, and means 'or holding* .eeeions in l lation during ilu: i the, ground.
