. ne it knqwn'that nsti/[SON DAVID EISEN..

D RALT'H, apitizenot't'he United States, resid.v 'ing at St. Paul,-Ramseyj county,' Minnesota,

have invented certainv new. and .useful Im.

-fprovements in Filters, 'of which the following` .is a full, clear, and .exactdescription 1 This invention-relates tewater distribution, and more especially to faucet-filters.; and the object ofthe .same is to'produce an improved ."lilter capable of .ready application to and ref-- *movalfrom a'faucet provided with proper -thefilterico'mplete 2 is a similar secthreads, and which filter is so construqteam 'Y timid-1y mi the filtering agentwin not freadtily become clogged nor shed its particles' into `the filtered-water receptacle.; -l

' This object l accomplish by-the'cons'tnuction set forth below and illustrated in the ac companying drawings@ whereinf-` Figure 'lis a central vertical section through tionswith the-'parts ot the lilten slightly s ep- Referringto `the saiddrawings, the bodyv or shellof this filter consists-of two hollow heinispherical members, T. being the top or upper one and -B the bottom or lower..` The:

vformer has exterior-threads tarou ud its mouth fora purpose to appear vbelow and at its upper end is provided with .an inlet-aperture I, enlarged, as at T', to form a shoulder-',--andin -A teriorly threaded,- as at z', above the saine,"- whercb'y it maybe screwed onto the exterior lth'reads'which usually occur-on the faucet now in general use in households. g is a gasket, as of leather 'or rubber, whichl is compressed between the mouth of theffaucetand the shoulder l" when the 'faucet is screwed Itightly to its support, thus preventing'leak+ age'. The lower member B is-cnp-shaped, as

` shown, andwith'in its m-outh` is provided with -threads b, adapted to engage those at the mouth of the upper member T, while just bev "ldwjthese threads is formed an-interiorshoul- /same size.

its foot rprojecting radially outward from the sereine. 653,739. (No mau.) v-

loweredge thereof, said foot resting upon the' y 'shoulder B when in place.

S is a-sheet or disk of silk. F isa similar -disk'of vfelt specially prepared for posean-d resting on the silk S.

. S is anupper silk disk resting on the this pu raround the 'upright 'portion of the L-shaped ring, andl G is a rubber-.or other gasket of the In. .assembling v.the fabric disks are placed in a pile and laid upon 'the upper edgegof the L-shaped "ringv and the plain ring brought down upon their edges, soas to clamp the latter'ti htly to the felt'. R isa plain metal ring of a size to fit closely the .parts above described Laing. Thewhole is thus-capa 1e ofteing,A f

handled readily without the. necessity of the operators hands coming in vactual contact with the -fabric, because the filter proper is clamped tightly withinja metal frame consistingof the rings R and L This filter audits -frame are then placed within the lower mem'-v ber B u'pon its shoulder B. and the' gasket G laid upon the ring R, and, iinally, the two -rnembers T and B are screwed together, so

that the lower edgeot the upper member T bears Iirmly down upon the gasket G and compresses the pile of disks vand rings uponl the shoulder B' to hold them in position-and prevent leaking from .the shell'or around the edges ofthe lilter proper. The devicc isthen attached to the mou-th of the faucet in a manner which will be clear. The parts can be separated, as for cleaning or repair, and again assembled in this manner.

The exact size, shape, and proportion of element-s are immaterial, and some considerable change .may be .made without departing from thefprinciple of my invention. For instance, on'e or both silks might sometimes be.

omitted, if preferred.

In use the water flowing in at l strikes the upper silk sheet,whcreby it is spread'out into a large Volume, so that it passes downward through all portions of the interior rather than through one spot at the centcronly, and, this sheet of silk also catches and holds at its edges such .particles of sand, dirt, and the like as will not pass through it. 'lhe water next passes through the felt, and,finall y, it passes `through thc lower sheet of4 silk, which in turn prevents detached particles of the felt from being delivered at O. I consider both ysheets of silk highly important for use in connection with a felt or fibrous sheet F for these reasons and for the further reason that the very fine mesh ofthe silk sheets permits the inflowing liquid to percolate through all parts thereof to the fiber rather than falling thereon at eertainpoints, as it would if a perforated plate were used, and the lower silk sheet permits Athe outiiowing water also tohave a free exit, while preventing particles of the fiber Y from being detached, and therefore'is of Agreat advantage; but they also possess the addi -tional advantages that the upper disk spreads the water over all parts of the chamber and delivers it evenly to all parts of the felt sheet,

while catching -particles which would otherwise injure or become embedded inthe felt'.

If desired, when the filter is being cleaned,

either orboth silk sheets can be simply in-L verted in place or they can be transposed the one for, the other, with or without inversion, and thus is aio'rded a quick and ready means of cleaning the filter without necessarily boiling or replacing the silk sheets, which would be the most thorough means of cleaning.

What is claimed as new is- 1. The herein-described faucet-filter, the same comprisinga shell-like bodyin two members of substantial cup shape, the upper having an inlet and the lower an outlet, the upper having exterior threads around its mouth,

the lower having interior threads'at its mouth" adapted to receive those on the upper member and also having a shoulder just below said threads, a lter proper consisting of a fab- 4 ric sheet removably clamped within a metal fr ame, lthe latter resting on said shoulder, and agasket between the lower edge of the upper member and the upper side of the filter-frame, as and for the purpose set forth.

2. In a filter, the combination with a shell like body in two cup-shaped members detachably connected atv their open edges, one

member having a shoulder opposite the edge of the other member; of a'filter proper consisting of two/sheets of silk with an interposed sheet of felt, said sheets being held upon said shoulder by said edge,.as and for the purpose 'set forth.

3. In a filter, the combination with a body having inlet and' outlet openings respectively above and below; of afilterproper supported within such body between the openings there-4 in and consisting of a fibrous sheet with silk sheets held close againstitslopposite faces, as

,right-portion, and a fabric filter-sheet passing at its edges overthe upright portion and clamped between it andI said plain ring, the entire filter with itsframe being held between said shoulder and said edge of the body meml be'rs, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
