IMPROVEMENT IN WELL- AND cIsIEsN EILTEES.

sPEc:c:EExsaeuIfIcJ:|511 T0 ALL WHOM IT MAY CONCERN:

B'e it known that I, WILLIAM I-I. WILEY, of Fredonia, in the county of Chatauqua, and State ,of-New York, u

have. invented a certain new and improved Well and Cistern Filterg and I do hereby declarethat the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of .this

specification, in which- Figure 1 is a central vertical section of my improvements, represented in the bottomofa well. Figure 2 is a horizontal section of the same in plane of line a az.

the filter.

Like letters designate corresponding parts in all the figures.

The object of my improvement is to provide a filter that may be attached to the tube of a well orcistern, and then let down 'into thesame, whereby the water is subject to a thorough ltration before it is pumped up for use; and the invention consists in the manner of constructing the filter, ashereafter described, by which it is specially adapted to the use and purpose above stated.

In the drawings, A represents the bottom portion of a well, with my improved lter therein; B,`(g. 1,) .is a section cf an iron well tube, coupled to the filter-tubeC, in any ordinary manner as shown;` E, the base-plate, xedly connected with the central tube C, to form the foundation and bottom of the ilter; F, G, the outer and inner sides of the iilterin g chamber, formed of porousm aterial, or partly perforated cases, secured as represented, or in any other suitable way, and D the upperfdisk or plate covering the filter. These disks are solid with the exception `of a hole in the upper one, D, for the passage of the tube C. The lowerbase-plate E and the tube C are preferably cast in a single piece, but may be rigidly connected together. by bolts or other means; the latter being provided with apertures or perforations, it', in its sides, of anydesired form for the iniiux of the water, and with both an internal and external thread at its upper end for coupling with tube B,-and for the purpose presently to be explained. The upper or cover plate, D, is made to fit ove'r the end of tube C,and rest upon the ends or top 4of the'cases and G, where it is firmly secured in place by the nut j, which screws on the end of the tube C, as shown in fig. 1. The sides may be of any porous'material, as baked earthen, brick, 31' other porous substance, or of the metallic cases F, G, which are provided with fine perforations, at and n', on one side of each and on opposite sides of the filter, so that the water as it enters the perforated side of the' outer case, cannot pass directly and readily through the packing, L, and inner case into the water chamber, I, but is compelled to percolate around between the two cases through the filtering material, L, (which may he of any'suitable kndltill it reachesthe perforations, n, n', in the inner case G, as shown by arrows most clearly in iig. 2. In wells and .cisterne where lead or wooden tubes are employed for elevating the water, I make `use of l a coupling,

H, (iig. 3,) for connecting either to the tube C of the filter. This'coupling is constructed as shown, and consists` of a thimb'le or collar provided witha ledge or shoulder, o, at the centre, running transversely 'around the inner .surface so as to lessen the size of the bore or opening, while atV both ends of the thimble, above and below this shoulder is cut an internal thread, for screwing on the end of C, and the endof I the wooden tube vIP, (shown in.

red lines.)y If a lead tube, Q, is 'desired to beused instead of the wooden one, the coupling is slipped over the same, so 'that the Bange or collar, s, at tube end of the tube will be below the shoulder, o. The coupling H is then screwed on the end of tube C, the end of ywhich presses the Bange 8,'against the shoulder o, firmly securing the lformer in place. Aring of rubber or other suitable packing material may be interposed between tl:\?\liangt...il and end of C, te insure the joint being water tight.

If desired. the cases F and Gr, either or both, may be made of crooks or cylinders of unglazed earthenware, when the perforations n n may be dispensed with, if preferred, as the earthenware is sufficiently porous to freely admit the rpercolation or passage of the water through it into the filtering space, and from thence into the .reservoirI and tube C. When so constructed, the pores of the oppositepside's may be` closed. by'glazing the surfaces on alternate sides to produce the effect lobtained by the mode of perforating, where metal is used.' A single crock or case of earthenware may be employed, thereby dispensing with the space and filtering material L, in which case it should be made of greater thickness; or the sides of the filter may be constructed `of bricks laid up in mortar, through which the water will readily pass 'by filtration, the brick or earthenware forming an excellent material for most eifectually straining and otherwise purifying the same.

Figure 3 isan enlarged sectional view of the cbupling H, for connecting either lead or wooden pipe with The object of my invention is to enable a compact and'portable iilter' to'be constructed in connectioii wtih the suction-pipe of .the pump so as to enable the complete filtering apparatus to be lowered 'into a well containling water by means of said pipe, and removed therefrom for repairs, when required, in like manner, and thisM I accomplish bymaking the base plate E serve as a platform on which the sides of the filtering chamber are erected, whether of brick, earthen, or of loose porous material supported by outer and inner walls, and completing the wh'oleiwith the cover-plate D, which is screwed down so-as to press closely on the sides. By coupling the central tube C to the pump-pipev B, the filter becomes attached to the pipe so as to be handled by i't. This obviates the-necessity of emptying a. well of water in lorder to construct or insert the lter in it, and makes it entirely unnecessary for workmen to descend into a well at all. What I claim and desire to secure by Letters Patent, is` v A portable well and eistern-iilter composed of the sub-plate E, filtering cylinder F G', disc D, nut or fastening j, andnperforated central tube C, combined with and attached tothe pump-tube B, the whole constructed and arranged substantially as and for the purposes set forth.` l

I alsoV claim the partially perforated sides F and G, when constructed as described, in combination with the porous packing lL, base-plates D, E, and tubes C and B, arranged and operating substantially in the manner and for the purpose described. f
