To all whom it may concern.'

Be it known that l, Grupo J. Wiesen- HonN, a citizen of the United" States, residing at Los Angeles, in the county of Los Angeles. and'St-ate 'of California, have invented a new and useful lNater-Percolator, ofwhich the following is a specification.

' This invention relates to a Water percolator, and has for its ob'ect to provide a simple construction Whic is durable in use, ecient in operation, which may be ,easily cleaned, and which will keep the filtered waterin a cool condition.

Referrino to the drawings Filgure 1 is a vertical longitudinal section throuofh the coinplete device. Fig. 2 is a vertica cross section taken diainetrically through the re n'iovable cap. Fig. 3 is a vertical. cross section taken diainetrically through the 'in- 'verted shield.

1 designates the reception reservoir which is preferably of china, or likemateriahwith a removable cover 2. The bottom 3 of the reception reservoir has an annular flange l directed upivardly, and within the fla-nge d and resting on the bottom 3 is a perforated disk or screen Above the disk 5 is a thick asbestos disk 6. Above the asbestos disk 6 isY a perforated disk or screen 7. Above the screen 7 is a series of asbestos sheets S. The foregoing elements which are contained Within the flange 4 are secured therein and held under soine compression by nir ins of a removable cap 9. p

f As clearly shown in Fig. 2. the cap 9 ooinprises a `ring 10 havino' slits 11. The ring 10 is foi-ined preferably of nietal and the Oslits 11 permit the ring to spring and flare at the bottom so as to lit and closely hug the beveled walls of the flange '4. The ring 10 has a doiviituriied 'flange 12', the latter having two inwardly directed flanges 13 and le, and secured between the flanges 13 and let is a disk 15 preferably of porous-stone. The

ca i tig'htly grip the saine, andthe porous-stone disk 15 confines the elements Within the flange et under pressure so that the disks 8 are prevented :troni curling or warping and are held perfectly flat. The cap 9 is readily removable from theflange d to give access to the interior thereof, it having frictional engagement withthe flange 4. vThe cap 9 confines the eleinentswithin the flange et so that when the reception reservoir 1 is rcmoved from the filter it may be tipped upvwhich is corrugated' as at 28. 'shield 27 is coarse gravel '29, and above the i) is forced doivn on the flange Il so as to side down, if desired, to empty out the' Water.

I Patented Mec. 2S.,

therein Without displacing tho/elements within the flange at. The object of this is to initially prepare the Water for the suhse` quent purification by removing the coarsest elements in suspension.-

rl`he reception reservoir 1 rests upon a flange 1G formed at the upper end of a filtering bowl 17, and the reception reservoir'l has a flange 18 which holds it in position on the flange 16. The filtering bowl 17 is formed with a shoulder 19 Whichrests upon Vthe upper riin of a Icooler 20. Within the filtering bowl 17 is an intermediate recep-V tacle Q1 which has a shoulder Q2 restin upon the shoulder 19 of the filtering bow 17, While the upper rim of the receptacle 21 has an inwardly-directed flange 23 which fornisa grip whereby theyreceptacle may be grasped to liftV the saine out of its seat in the filtering bovvl 12'. The bottoni of the receptacle 21 is concave, as. shown, and provided ivith perforations 24.. 1ilfithin the ren ceptzicle 21 is mineral liber Wooly 25. The bottoni of the filtering bowl 17 is provided with orifices 26 and above the orifices 2G is an inverted disk shield 27, the lower edge of above the grvel 29 is a filtering material 30 which nia y preferably consist of charcoal, bone ear.- bon and'granite. The inverted shield 2i' prevents the gravel and filtering material within the bowl 17 from clogging the` orifices 26, and the corrugated edge of the .shield Q7 permits the water which has seeped through the gravel to pass through the bottoni of the bowl 17 into the cooler 20. orifices 26 are respectively fe'iv in nuinb. r and together with the shield-27 restrict the flow of water in such a way that the Water necessarily passes very slowly 'through the filtering material within the boivl 17,asl it has been found in practice thatthe beneficial effects of the material on the water areunct as great when the water passes quickly through it as when the water is kept in contact with the inixture for seine time. The

cooler 20 rests upon a. drip pan 31 and the lower. part of the cooler is provided with a faucet 32.

Tater within the cooler is cooled by evaporation of water which has percolated. through the porous walls of the cooler, and

tho seepage froin the cooler flows down the sides thereof and :is caught Within the drip 'llhe ics pan 3i, the latter Vbeing furnished-.lividiiin outlet 33 for drawing oii the water which accumulates therein.

' ll/Yliet I claim is l. A lter comprising a cooler, a. bowl resting on the cooler, filtering material in i said bowl, an intermediate receptacle within said' bowl, a reception reservoir resting on the upper rim ot' seid bowl, filtering main t e reception reservoir, a removable cap von 'said flange comprising a metallic ring, 'the Walls of which are slitted longitudinally and adapted to be wedged onto the flange of the reception reservoir, said ring havin 0' two inwardly directed ianges, and s disk oiporons material vengaged by said flanges and confining the filtering material. A

2. In e filter, e reception reservoir, the bottom of Whichliasnn opening and is formed 'ivitli un upwardlyl directed enge around said opening, @perforated disk over said opening at the bottom of said Hange, a. ,l

thick asbestos disk above said perforated disk, ziescreen above said asbestos disk, a. se-

vries ofthinV sheets, of asbestos 4above said screen, e' remove-ble cap frictionally engagl ing seid flange, endr a porous stone disk se' cured .to seid cap and confining the foregoing elements Within said flange, a filtering bowlv supporting sid reception reservoir, .an intermediate lreceptacle within the filtering bowl, the upper rim of4 seid intermediate re ceptacle having an inwardly directed fixings, filtering material-in the intermediate receptacle', ltltering material in the bowl, and n cooler supporting the bowl. t
