Application filed March 3, 1916. Serial No. 81,983.
.To all whom t 'ma 1/ conce/ilu Be it known that I, Enna-uu G. AomlsoN, n citizen Of thenited States, residing at New York, in the county of New York and Stute of New York, juive invented certain new and useful'Improvements in Filters, of uhich the following is :i specification.
This invention. is zi ,hlt-efr intended pri-- iuzlrily for household use, fal'though applicable to other purposes.
The Object of th-invention is to provide e. simple and inexpensive filter which is highly effective for theremoval of sus pencled impurities from water, und is very easily, quickly and `perfectly cleansed.
A preferred embodiment of the invention is illustrated in the accompanying rlrewing,` wherein thev ligure is a central vertical sec-1 .tionloif a filter element with its mounting,A
Y. A i i The. hlteringr member proper, in the ein bodiment of' the invention chosen for illustration, comprises e relatively thin and prfeierably slightly arched septum l. Of a? suitable porous material, hnvingi Iformedl integral therewith an encircling ring or' flange. 2, hereinafter' referred to as the beiiring niemher. As showzn'tliis beziring member is "planes The v/bearing member therefore ,serves as n protection tor the more .rfige septum .in every positiain, und. nwreover, the' filter members-mw,- he i. elv stacked for storage transport he beaming menioer is prefers i, eine permele materiel as the. septum l, but of such dimensions that rthe passage of waiter." to .its i, .ivy under conditions oi use is negliech-the. besring member 2, or muy be reiclere imperme :is by impreinntion with pan 1 suitable materiel. he mounting iliustreted comp-:ses upper ower members 3 and Ll, 'preferably of ron or other metal, and adapted to be fnpei'l upon the upper and lower bearing planes of the ring 2 hy peripheral bolts 5 z s cle or equivalent elements. Gaskets i5 may be used to prey'ent leakage and to avoid langeg.: of friuturing the bearing nieinoer, al-
` though these may be unnecessary when the 'tieinirig surfe ses nre true planes. The upper Specification of Letters Patent.

member 3 is attached tO the source of watersupply under pressure, the Wat-er entering" lhrough pipe 7, While the filtered water escapes through the orifice 8. It will be 0b.-
served that the pressure of the Water is exerted' against the convex side of the arched septum 1, so that the latter niy be made rery thin while yet capable of withstanding very considerable pressures.
In Order that the position of the filter member muy notl be accidentally reversed when rephicingiit in the mounting, I prefer to provide on'one of its surfaces :in annular ribV 9, engaging a eorresi'ionding groove 10 in one of the elements of the mounting, the construction serving lalso to center the lter member. Of course any other mea-ns for making the position of the filter 'member irreversible may be used, or such be dispensed with.
The invention as disclosed in the present application .relates primarilyto the vstrue-r vtural features of the filter, as distinguished from the material. thereof. While the sep- 4in'ezins may tum and its encircling bearing member mayv be formed o'hurned clay, biscuit-ware, un-
porcelain, or any of the other usual ceramiciiltering media-which are applicable to the construction o such forms, 'I prefer in all cases to form the filter member from ein" or other amorphous substance which has been subjected 'to n. process 'of partiel orA complete rlelocculntiain anti thereoterluiked or tivi, described and claimed in my @pending anilivcritlon, Serial. No. 81,984 tiled liei'e-iifitli..
it will be Observed that in this construel'ion there-is no pos niity of the passage of wet-er to.. the discharge orifice 8, except znrough the filtering sept-um. Since there is no joint between the septum i and the bearing member any leakage past the filtermeniber, or through the joints between the lter-member und its mounting, would merely flow to waste without danger of con-v Y member of greater thickness than'said septum, and said septum Wholly comprised between the upper and lower planes of said bearing member.
3. A filter element comprising asn arched, porous septum, and a surrounding bearing member integral therewith, said septum wholly comprised between the upper and lower planes of said bearing member.
In testimony whereof I alix my signature.
EDWARD G. ACHESON.
