WELL CASING.

Application filed March 6, 1924. Serial No. 697,388.

This invention relates to well casings and has-for its object to generally improve upon such struc-tures so as to provide a device of this nature having a sturdy, durable, and light structure which may be easily assembled and which will be efficient in use.

Anotherimportant object of the invention is to provide sections of a well casing having associated therewith novel straining means. u

A still further object of the invention is to provide a well casing including a plurality of superimposed sections one of which is adapted to be disposed in water and embodies a filter through which the water must' pass to flow into the casing.

With the above and numerous other objects in view as will appear as the description progresses, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of the Well casing embodying my invention, `portionsthereof beine' shown in section.

Figurt 2 is a detail longitudinal sectlon through the intermediate portion D of the casing,

Figure 3 is a tranverse section taken substantially on the line 3-3 of Figure 2 looking in the direction of the arrow,

Figure 4 is an elevation showing portions of the sections,

Figure 5 is a. detail transverse section taken substantially on the line 5-5 of Figure 4 looking in the direction of the arrows,

Figure 6 is a transverse section taken o n the line 6-6 of Figure 4' looking in the d1'- rection of 'the arrows,

Figure 7 is a perspective view of the filter block,

Figure 8'is a perspective view of the housf ing for the iilter block,

Figure 9 is a longitudinal section through a modified form of the casing,

Figure 10 is a transverse section therethrough taken substantially on the lme 10-10 of Figure 9 looking in the direction of the arrows, and

Figure 1.1 is a detail perspective showing a portion of the modified form of' the casing.

Referring to the drawing in detail it will be seen that A designates the outer casing rwhich is extended down as far as water level B. The inner casing is-spaced from the outer casing and is formed from a plurality of sections, The bottom section C is disposed below the Water. The section D is disposed above section C in superimposed relation thereto so as to be positioned in the water. A section E is mounted on top ofsection D and a' beveled section F is mounted 05 thereon. This beveled section Fis connected to a pipe G of suitable length. The space above the section E is filled with gravel as is shown at H and con-crete is poured on top of the gravel to fill the remaining space between the inner casing and the outer casing as is indicated at J. The sections of the inner casing are all joined together in the same manner preferably by the engagement of threaded extensions 5. tion C merely acts as a hollov.7 reservoir and also as a foundation or anchor for the casing. Section D acts as a filter and embodies. a novel structure including the in- Secner cylindrical member 10 radiating from 80 which are the tWo series of tubes l1, one series being disposed adjacent the upper end andthe other series disposed adjacent the lower end. Corresponding tubs 11 of the tWO series connect with housings 12 in which are 85 supported filter blocks 13 having a plurality of slots 14 therein preferably extending transversely thereof. These slots are larger toward the inner face of the block 13 as is indicated to advantage in Figure 2. A band 15 is suitably lixcd to the collar 16 of a conical shaped member 17 the smaller end of .which terminates in a collar 18 fixed' to the inner cylindrical member 10. A pair of tubes 19 are fastened to the band 15 and de- 95 pend therefrom as to be fastened to a lower band 20 upon which the housings 12 rest. As is shown to advantage in Figures 4 and 8 tabs 22 are provided at the tops and bottoms of the housings 12 and are fixed to the bands 16 and 20. The filter blocks 13 are held within the housing 12 by means ot I lips 23 at the tops and bottoms thereof which are bent over upon the blocks as is shown to advantage in Figure 2. The housings are provided with side strips 24 which meet each other as is seen in Figure 3 and it is preferable to fill the space between the housings and the inner cylindrical member 10 f with vconcrete orsimilar material.

l n mounted upon the section F tends to divert Vthe gravel as it is being poured in the outer of the seztion F from the cylinder 26 and an inner cylinderl 27 the upper end of the outer cylinder converges and connects with the inner cylinder. Section F is similar in construction to section E except that the outer cylinder is tapered. A

The outer cylinder 26 of the section E forms .a protective casing to shield the inner conducting cylinder 27 from the pressure of the packed gravel H which isvfilled about this section. The outer tapered cylinder casing and likewise protects the lower end pressure of the gravel. L s

The modification of the invention Vshown in Figures 9, 10 and ll shows a plurality of sections held together by means of cables 30 which will be attached to the end sections by rivets 31 or in any other suitable manner. Each section shown in this modification consists of an outer cylinder 32 `and an inner cylinder -33. The inner cylinder is longer than the outer cylinder and the exposed end is provided with a pluralityof radiating fins or plates 34 which are connected to the outer cylinder. The space between the cylinders is filled with gravel or the like. From this construction it is obvious that a portion of the inner cylinder 33v is exposed so that the water may be receivedl in the inner cylinder through the openings.

.The sections embodied in this modification are preferably to be employed upon wells of comparatively large diameter and used in place of the upper sections shown in Figure l indicated by the letters `F and G, above the 'water `line and ravel filling, above the sections C, D and d3 which may remain of the type shown inthe preferred form in this figure.

I have, in the present instance, shown and described the preferred embodiment of my invention which will give in practice satisfactory and reliable results, and it is to be understood that the same are susceptible of modifications in various particulars such as the details of construction, and the combination and arrangement of parts, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

It is evident that this well casing is section having adapted to be used with a large variety of pumps and as such devices are well known 'in the art I have not shown any in the accompanying drawing. The device is particularly adapted for use in water wells, but, of course, may be useful in other wells and I do not wish to limit myself to the particular illustration and the use mentioned here- 1n. t v

Having .thus described my invention, what I claim as new is:

l. A well casing section including a cylindrical core, avvconical shaped member connected to the core, a band fixed to the conical shaped member, a second band, tubes concomprising a bottom section forming a' reservoir, a filter section arranged in vertically aligned position with the reservoir a plurality of openings formed in the si e walls communicating with the interior thereof, the said section being of assembled formation to permit replacement of the parts, a conducting section disposed above the` filter section'and communi- (ating therewith provided with an outer cylin rical casing assembled to provide a unitary structure, and a plurality of con-v ducting sections communicating'with and disposed above the said last mentioned secseries of radially directed tubes connected to the conducting tube and to the housings and communicating therewith so as to conduct the water through the blocks to the central conducting tube. Y

In testimony whereof I aiix my si ature.

ARTHUR C. H LM.
