Specification of Letters Eatent. Application filed January 6, 1914. Serial fie. 810,613.

The main omect of the isr body andupper and lower sections connected to each other and acting as a reinforcing element for the body and as a means for securing the blocks against independent nioveinent. each of the blocks being providcd ivith screen openings for the usual purpose.
The invention in the preferred form. of details will be described in the following specification, reference being had particularly to the accoi'npanying drawings,- in which Figure 1 is a perspective view of one sec-- tion of the casin Fig. 2 is a vertical central section of the same. Fig. 3 is a perspective of one of the blocks of which the casing wall is constructed. Fig. fl is a perspective of one of the connecting rings. 5 is a perspective of the casing head. Fig. 6 is a perspective of one of the screen sections. Fig. 7 is an enlarged broken sectional screen formation.
QVilh particular reference to the acconipauying drawings, the improved well easing comprises a tubular main section 1 which in this instance is made up oi a series oi: superimposed vertically ofi'set cement blocks'il which blocks are suitably. curved to form a section of the de ired diameter when the blocks are arranged in proper relative posi tions. Each block is formed with anelongated opening 3 adjacent each end thereof, the outer surface: of the block surrounding the edge of each-opening 3,,being formed with a depression a to receive a screen.
.lhe screens, one of which is used. for each open .3 3, comprise plates having an edge formation conforming to the depression 4: so that they r be seated therein toclose the opening 'The plates 5 are formed eurther 'lcormed withlongitudi- Z prov ding-the screen. On the EHME H. B uunorr,
in place by being seated in the present invention is the provision of a well casing made up of series of blocks cemented to form a tubuview illustrating particularly therihs 6 to strengthen the inner surface each plate 5 is provided with a longitudinally extending rodS inovably con- .nccted to the plate through the medium of tie straps 9, the ends of the rod being bent at right angles to the plate and formed with hook terminals 10. The plates are secured depressions i and the hook terminals 10 engage beneath or against the inner slls of the openings 3,
as will be plain from the drawings.
lnccnnection with the casingsection described, I provide a shoe for the lower end thereof. this shoe being designed to aid in fitting the casing downward as the sand and earth are removed from the interior of the casing. The improved shoe comprises a metallic ring 11 of appreciable height and sufiicient thickness to insure a structure of the proper weight. The ring is of greatest thickness at its upper edge, so that at said upper, edge it presents a comparatively broad bearing surface 12. the inner and outer sur-' face of the side wall of the ringbeing projected from the inn and outer edges of? the bearing surface on slight outwardly curving lines, the degree of curvature of the inner surface being greater than that of the outer surface. so that said surfaces meet at the lower edge of the ring; in comparative coincidence, presenting a comparatively thin cutting edge 13. Tlhe'cutting shoe described is formed with radially projecting lugs 14 coincident with the bearing; surface and ex tending); beyond the outer surface of the rim.
A connecting plate 15 in the form of a flat ring is arranged upon the upper end of the casing, the said ring heine: formed with radial lugs 16 arranged in accordance with the lugs on the shoe. With the shoe and connecting ring in place the lugs 14,16 are connected by tie rods 17 joining the vertically alined lugs and brace and truing' rods 13 connecting the offset or diagonally inclined lugs. By means of the rods 17 and 18 the respective blocks of the casing are secured against the possibility of independent movement and the casing' as a Whole is held intact. v
The easily; as an entirety is inadeup-of a plurality of easing sections such as described, the connecting ring at the upper cndof one casing section serving; as a-base or support for the lower edge or the immediately superiniposed section.
