FILTER.
SPECIFICATION forming part of Letters Patent No. 614,480, dated November 22, 1898. Application iiled April 20, 1898. Serial No. 678,284. (No model.)
T0 all whom t may concern:
Be it known that we, WILLIAM B. LINDSAY and WILLIAM VE. TONNER, citizens of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented a new and useful Filter, of which the following is a specification.-
This invention relates generally to filters, and more particularly to that class thereof known as porous-wall filters.
` The object of the invention is to provide a filter embodying an outer shell, a lteringcylinder, 'a cleaner, and suitable meansfor securing the filtering-cylinder and cleaner within the cylinder or shell.
Another object of the invention is the simplicity of the arrangement, combination, and construction of the various parts.
Another object of the invention is to provide a filter embodying these characteristics and advantages which sha-ll be cheaper and easier to construct than the filters heretofore constructed.
Another object is to so construct the filteringAcylinder that it will wear much longer than the filtering-cylinders now in use, the common objection to such filtering-cylinders being that they are Worn away too rapidly by cleaning. l
With these various objects in view our invention consists, essentially, of an outer cylindrical shell or case having a top or cover rigidly attached thereto and provided with a circular opening, preferably to one side of the center, a filtering-tube of a diameter adapted to pass through the circular opening in the top and also preferably arranged eccentrically within the cylinder or shell, a cap-plate or cover adapted to fit the circular opening in the top, said cap-plate or cover fitting an aperture through which passes the dischargetube leading from the filtering-cylinder, and a suitable cleaner with operating mechanism arranged between the iltering'cylinder and the outer cylindrical case or shell.
The invention consists also in constructing the ltering-cylinder in such a manner as to prevent undue wear upon said cylinder, thereby prolonging the life of the filter without impairing its filtering qualities.
The invention consists also in providing suitable guide means for steadying the movement of the cleaner.
The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claims.
,In the drawings forming a part of this specilication, Figure l is a perspective view of a filter constructed in accordance with our 6o invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a detail view of the top. Fig. 4 is a detail view of the iltering-cylinder. Fig. 5 is a detail View of the bottom.
In constructing thefilter in accordance with our invention We employ a cylindrical shell or tube A, which is preferably asection of a drawn-steel tube. It will of course be understood that it may be constructed of any other suitable material. This cylindrical shell 7o A is provided with a suitable base or bottom B, preferably of cast metal, said bottom having a suitable aperture produced therein for the attachment of a draw-off cock B. The bottom is also provided with an interior journalstud B2 and also with parallel guide- Iianges B3, said iianges being adapted to guide the cleaner hereinafter described, while the journal-stud acts as a suitable bearing for the ltering-cylinder, the construction 'of which 8o will be fully described hereinafter. i
Upon the upper end of the cylindrical shell A is fastened a top or cover C, said top or cover, as also the base, being rigidly secured in any desirable manner, such as brazing, soldering, or riveting. This top or cover C is constructed with a circular opening O', preferably arranged slightly to one side of the center of the cylindrical tube or shell and of a size sufficient to permit the passage of the 9o filtering tube or cylinder D, which is passed into the cylindrical shell A through the circular opening in the top O, said filtering-tube havinga discharge-tube D passing entirely through the same, the lower end being closed and terminating in a journal .adapted to fit in the stud-bearing B2, previously referred to as being formed integral with the bottom or base. This discharge-tube D is provided with a series of openings D2 within the iilterrco ing-cylinder and through which the Water enters into the discharge-tube, the upper end of said discharge-tube being provided with a suitable discharge cock or faucet D3. Surrounding the circular opening C is a flange O2, preferably threaded and vupon which is secured the cap E,said cap having a central opening E,through which the discharge-tube from the iiltering-cylinder passes, and, if desired, may be provided with a suitable stuffing-box E2 to prevent leakage.
A cleaner preferably constructed from natural stone is arranged between the inner filtering-cylinder and the outer cylindrical shell, ample space being provided therefor by arranging said filtering-cylinder eccentrically or to one side of the center of the cylindrical shell or case A. This cleaner F rests at its lower end between the guide-flanges B3 and is provided intermediate its ends with a suitable plunger Gr, which is located in the inletpipe leading into the cylindrical case or shell A, said cleaner being caused to move into cont-act with the filtering-cylinder by the water-pressure. The plunger is provided with a suitable opening H, through which the water can pass into the shell or case A, from whence it passes through the inner or :filtering tube and then out through the dischargetube.
In order to clean the filter, the draw-off cock is opened, thereby relieving the filtering-cylinder from external pressure, and as the cleaner is forced against the exterior of said cylinder by the water-pressure the said cylinder is given a few revolutions through the medium of the tube and the exterior surface of said cylinder is cleaned of all sediment. In actual practice We have found that the cleaner wears away the filtering-tube too rapidly, andin order to obviate this we propose to construct the upper and lower ends of the filtering-cylinder with bands which will not be worn away so rapidly, and thereby prolong the life or use of the said filteringcylinder. In order to do this, we can surround the upper and lower ends of the cylinder with either a gutta-percha, wooden, or metallic band; but in practice we prefer to harden the said ends by impregnating them with a hardening solution-such as waterglass, shellac, or other material. By hardening the ends and making them wear less rapidly we are enabled to prolong the use of the filtering-cylinder without destroying its filtering properties. By attaching the top or cover rigidly to the outer shell or case and providing the same with a circular opening arranged eccentrically we are enabled to provide a filter in which the filtering tube or cylinder can be quickly and easily arranged within the outer shell or case at one side of the center and the cap quickly and easily secured tothe top or cover without the use of clamping-rings or screw-bolts.
It will thus be seen that we provide an exceedingly cheap, simple, and eiiicient construction of filter of the kind described and which will obviate all of the objections now existing against this class of filters of which are aware.
aving thus described our invention, what laim as new, and desire to secure by Let- Patent, is
" ite f the cla s described,the combination with the outer cylindrical case orI shell having the top and bottom rigidly secured thereto, said top having a circular opening therein, of the filtering tube or cylinder adapted to be passed through the circular opening in the top and journaled upon the bottom of the shell or case, the dischargetube passing through the said filtering tube or cylinder and extending upwardly therefrom, and the cap through which the discharge-tube passes, said cap being adapted 4to be fastened to the top or cover and close the circular opening, substantially as shown and described.
2. In a filter of the class described, the combination with the outer shell or case having the top and bottom rigidly secured thereto, said top having a circular opening at one side of the center, of the filtering tube or cylinder adapted to be passed through the circular opening and arran ged within the shell or case, the discharge-tube, and the cap adapted to be fitted upon the top or cover and close the circular opening therein, the discharge-tube passing through the said cap, substantially as shown and described.
3. In a filter of thekind described, the combination with the outer shell or case having the top and bottom rigidly secured thereto, the bottom having a bearing-stud and the guide-flanges integral therewith, the top or cover having a circular opening produced therein, said circular opening being eccentric, the filtering tube or cylinder adapted to pass through the circular opening and rest within the outer shell or case, the cleaner arranged between the outer shell or case and the inner filtering-cylinder, the lower end thereof adapted to rest between the guideflanges, means for forcing the said cleaner against the filtering-cylinder, t-he cap adapted to fit and cover the circular opening of the top, and the discharge-tube extending from the filtering tube or cylinder and passing through the cap, substantially as shown and described.
4. In a filter of the kind described, a filtering tube or cylinder having its ends harder than the intermediate portions of the cylinder, substantially as shown and described.
5. In a filter of the kind described, the combination with the outer cylindrical shell having the top and bottom rigidly attached thereto, the top having a circular opening produced therein at one side of the center, said opening having a threaded flange,of the screwcap adapted to fit upon the said threaded Harige and cover the circular opening, substantially as shown and described.
