WELL-STRAIN ER.

SPECIFICATION forming part of Letters Patent No. 604,651, dated vMay 24, 1898 Application filed September 22,1897. Serial 1% 662,642. (Nomodell) T0 at whom it may concern: Be it known that I, JOHN BOOTH, a citizen residing at Bellville, in the county of Austin and State of Texas, have invented certain new and useful Improve-1 ments in Well-Strainers; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention ,relates to improvements in well-strainers, and has for its object to provide a well-strainer of such a construction that by simply varying its size it may be adapted for use in large or small wells and by varying shape, and that without modifying the essential features of the strainer;

My invention will be clearly understood by reference to the accompanying drawings, wherein the same parts are indicated by the Figure 1 represents a side elevation of a portion of a section of well-strainer constructed according to my invention in a hexagonal form, and Fig. 2 represents an end elevation of the same. Fig. 3 represents a view similar to Fig. 2, showing another form of strainer. Fig. 4 represents a View similar to Figs. 2 and 3, illustrating still anotherform of strainer; and Fig. 5 "represents a side elevation of the cylindrical form of strainer shown in Fig. 4.

In Figs. 1 and 2, A represents 'a strainer of a hexagonal form, composed of rectangular side pieces A, beveled at their side edges and fitted together, asv at a, and held together by any suitable means. Each of these side pieces A is provided with a plurality of larger, preferably circular, openings A", which extend about halfway the'rethrough from the outer side and connect with smaller, prefer ably circular, openings a, which extend to the inner side of the side piece A. Within the bottom or inner end of the larger opening A and over the'inner end of the smaller opening a is fitted and secured a piece of wire-gauze a and over the outer end of the, larger opening A is also fitted another piece of-wire-gauze a which is suitably secured in position upon the side piece A. Within the space between the two pieces of wire-gauze a and a in the inner and outer ends, respec wells of any desired tively, .of the larger opening A 1s preferably placed a filling of sponge or other similar porous, material, as shown at a in Figs. 1 and 2. One endof the strainer rests upon the bottom of the well in practice, and the water or other liquid in order to enter the hollow space within the strainer must pass through the openings A and a". The openings A, leading to the outer sides of the strainer, being larger, present a larger filtering area for the water to pass through, and. the inner openings a", being smaller, present a' contracted space for the escape of the water to the interior of the strainer, thus insuring'a perfect filtration. v I c When the filtering material and the wire gauze become so 'cloddedwith sediment as to retard the operation of the strainer, the whole strainer may be readily lifted bodily from the.

well and cleaned, or the Y may be removed and new material put in its place, and the strainer may then be replace in the well with ease and simplicity. I

In Fig. 3, B represents astrainer of a quad- 1'angular.form-that is, made up of 'four side pieces B of equal width, having their edges overlapping and secured, together in any'suitable manner, as at b. each provided with a plurality of larger outer openings B and smaller and with pieces of wire-gauze b and I) over the inner and outer openings,'respectively,

-and-spon'ge'or similar filtering material b between the saidv pieces of wire gauze, all con structed and arranged in a precisely similar manner. to the corresponding parts shown in Figs. 1 and 2'and above described.;

.In' Figs. 4 and 5, 0 represents a strainer of a cylindrical form and illustrates such astrainer as-made of molded cement or a section of terra'-' cotta pipe. In this form of strainer the. required number of openings 0 and 0 are arranged at properintervals upon the shell of the strainer, and the pieces of wire-gauze c not be used, as desired, asalso, however,

would be the case with-the forms her'einbefore described. v

The forms of strainers shown in Figs. 1,-2,

old filtering material.

The side pieces B are inner openings b and c are preferably molded into the-shell" of the strainer.

The filtering material of shownmay or may and 3 may be made of pieces of heavy lum-,

in, as general form'may be changed at will tosuit conditions without departing from the spirit,

of my invention. Not only may the general shape of the strainer be varied, but the size as well.

Having thus described my invention, what .I claim, and desire to secure by Letters Patent of the United States, is

1. In a well-strainer, the combination of a hollow shell orcasing made up of-'a plurality of sections fitted together, and provided externally with a plurality of, larger openings leading partially therethrough and internally with a corresponding number of smaller openings leading to said larger eriternal openings; a'strainer covering the passage between each Y larger'and' corresponding smaller opening;

arid a strainer covering each larger opening, substantially as described.-

2. In a well-strainer, the combination with a .hollow shell or casing made of cement molded into the desired shapeand provided externally with a plurality of larger openings leading partially therethrough,' and-internally with a corresponding number of smaller openings leading to said larger external openings; sheets of wire-gauze covering the inner ends of said smaller openings, and other sheets of wire-gauze covering the outer ends of said larger openings, said sheets of gauze being embedded at their edges in said cement, substantially as described. I

. 3. In a well-strainer, the combination with a hollow shell or casing made of cement, molded into the desired shape and provided externally with a plurality of openings leading partially therethrough, and internallywith smaller openings leading to said external openings, sheetsof wire-gauze covering the outer ends ,of said smaller openings, and other sheets of wire-gauze covering the outer 'ends of said said sheets of gauze being larger openings, embedded at their edges in said cement casing, and a porous filterin g materialfilling the space between the parallel layers of wiregauze, substantially as described.

' Intestimony whereof I affix my signature in presence-of two witnesses. I
