g UNITED STATES To all who/. 1, it may concern Be it known that I, DABXEY ll. MAURY, a citizen of the United States,residi ug at Peoria, inthe county of Peoria and State of Illinois,

5 have invented certain provements in VVelI-Inlets, of which the'following is a specificatio This invention relates to improvements in inlets or inlet-terminalsforincased wells, parc ticularly for what are commonly known as "open wells, and the diameter of which is so great that they can actually be entered instead of being merely accessible from the top, as isthe case with the ordinary bored or driven well.

The objects of the invention are to provide an improved construction by-the employment of which the use of screens or strainers for removing debris-and sediment from the incoming water can be done away with with even better results, so far as the obtaining of an adequate volume of clear water is concerned, than if such strainers were used, and to provide a generally improved construction of inlet-terminal for open wells, particularly of that type of such wells in which that portion of the interior above the inlet-terminal forms a dry well adapted to receive pumping machinery of any suitable variety.

The invention consists in the matters herein set forth, and particularly pointed out'in the appended claims.

In the accompanying drawings, Figure 1 is a sectional view of an ordinar open well provided with an inlet-termina accordance with my improvements.- shows a what more highly organized inlet-terminal Fig. 2

of some details of the construction shown in on line5 5 of Fig. 1. H

In Fig. 1 of said drawings, 1 designates the steel casing on an ordinary open well W of indefinite depth and the diameter of which may be/ n'ything desired, except that itmnst always he large enough to be entered, and s accessible from its interior. The lowermost stance the inlet-terminal T of the well, and it isaccordingly punched through with a great new and useful Im-. suitable means removable moved, leaving the holes 2 constructed in' similar welliprovided with a some constructed in accordance with myimprovements.

number of holes 2, through which the water from the surrounding earth' is ultimately designed to enter. In the sinking of the well, tightly closed by however, these holes 2 are from the interior of the casing, such means consisting in this instance and desirably by metal-coveringplates 3, that are removably secured to the casing by belts or cap-screws 4, which while in place may be holding the covers tightly readily unscrewed to permit the removal of the plates.

In the sinking of the well either the pneumatic process or any of the other well-known methods of accomplishing work of this character may be employed, the cover-plates 3 in the meantime being bolted firmly in place. Then when the well has been sunk to the proper depth and supplied, if necessary, with a bottom plate or grating G the covers 3 are nnbolted from within and permanently teuncovered a d free to permit the influx of water throiifh them. The first water entering throu h these holes (which are desirably made of ye siderable diameter-threc-fourths of/nn inch or more, for example- 50 that theyare not likely to become clogged). will bring with itmore or less sand, gravel, and the like; but as the flow continues such finer material as can snccessfully pass through the holes will be grad ually washed into and may be pumped out of the well, while the crowding toward the easing of larger stones and, pieces of rock will ultimately cover the inlet-openings and build.

up a natu ral filter about them,which will keep out the furt er entrance of'sandv and sediment withofig interfering with the influx'of water. j

In the more highly organized construction (shown in Fig. 2) the-inlet-terminal consists of a skeleton outer cylinder and a perforated inner cylinder C, which latter corresponds with the terminal cylinder T of themore elemental construction (shown in Fig. 1).and is similarly provided with holesil, that are initially closed by removable cover-plates 3, as

previously described in connection with said Fig. 1. The skeleton outer cylinder is formed,

as herein shown, of circularhoops or hands 6, 7, 8, and 9, of angle or channel iron, that are connected together at intervals by vertiw cal strips 10; A bulkhead 11, provided with Y manholes, (not shown in the'd'rawings',) 01- tends between the upper hoop or band 6 and the upper. end of the-inner cylinder, and a downwardly-flaring bottom plat'e'12 extends between the lower end of said inner cylinder and the lower hoop or band 9, while an angular bracing 13 serves to strengthen the structure betw cylinderis I en originally and throughout the entire process of sinking the well (which process may, as before, be of any character'deem most suitable for the particular situation in hand, whether neumatic or otherwis'e) com pletely closed u by sections 8, of shooting,

which are-arranged to slide longitudinall be-' tween the vertical strips 10, being he d in place there by wider strips 14, secured over the strips 10, to form gnideways for the sec IOv tions. I This leaves between the outer and inner cylinders and between the upper bulk- During the sinking 0 head 11 and bottom plate 12 an inclos'ed space F, which is filled in through the manholes with stones and gravel to form a filter-hedonscreen, the material being desirably packed in by hand, so as to bring the coarsest portions next to the perforated inner cylinder.

is completely incl by the, sheeting, and the terminal presents'to the surrounding earth a-continnous and substantially smooth exterior, which does not interfere with the sinking operation. The narrow 'spaces between the sections of sheeting and the upper hoop 6' on the one side and, the steel casing of the well W on the other are designed to be closed and made tight against air or water during sinking by calking with hemp, wooden wedges, or other suitable material, over which ispreferably then poured melted coal-tar pitch. Then upon completion of the sinking operation the sheeting is withdrawn section by section, (by applying a suitable tackle to an eye or hook 1.5 at the upper end 17, through which a suction-pipe 18 is exv tended downwardly into the lowerpart of the i by a gate-valve V, from the upper sFe'of of each section and pulling it vertically upwai d from between its guides,) and this leaves the outer circumference of the terminal entirely open, so that the water from the surrounding earth can enter it freely and percolate throughrthe filter-bed toward the inletopenings 2, which when uncovered by'the re-' moval of the plates 3 admit the water to the inner cylinder 0. Before the removal of the plates 8 a filling of stones and gravelwill desirablybe packed in beneaththe conical bottom wall12 and beneatha perforated bottom plate 16, secured in the lower end of the cyl- --inder C-and through which also water may enter the latter. The top of the iuner'cylinder is herein shown as closed by a tight head cylinder 0.
