Stute ot' California. herve invented new and useful lnipi'ovements in "Vnenum-Cleaners, o which the following is n Speeitioation.
ylhie invention relates to vaeunni @lenneis oi the volume type oi' those inwvhieh the onction is induced oy l1 centrifugal fan; the cleaning being lone by 'the nfllnt't of e lelntively large "volume o" nii high velooity'.
rthe object of the present invention is; to niovide simple., practical machine., either 'toi' stationery o1 portable use, but partienliii'ly designed es :i portable ole/nnen toi1 use in homeS und in which machine the usual settling heg is done away with and in place thereof there is an especially designed metal ieinoinhle il'iistoolleetion Chamber.
Une of the ehie't objections to vacuum cleaners usino' n dnstwolllotion hep; is the oliengi'eenble Ientin'e of the ling nnfl 'ele-ning it. in my oonsswnetion zin eesiljv removable i'eeeptnole employed which can he voi-jv ooni'enie tljyf emptied.

The invention consiste of the parte :incl the Combination sind Construction of p-.iitfi ..5 lieieinntei more fully tlesoiyibefl and oleiinecl. having i'efeienoe to the neooinpnnyin@I drawings. in. Wliieli ligne l is n longitmlinnl vertien-.l seetion illnetnting the invention. Fig. i); is e. l"1oii- Zontzil section on line li r llig. "l, `with n.

[i represents :l ense of suitnlole eine :intl Shape, the lon'eiportion of which foune ai housinga .zoi' the motos' and the flw'l, while the iipnei limit of the one@ nloove the tens is adapted to receive n iemovahle clust recept: ole 3. This removable. floot ieoeptaule teleeeopes unil fits inside of the top ot the ons@ .3%. und hns its bottom contiguous to :i partition plate (l in onse il.. Plate o has n central hole T registering with the eye 8 of the nppei fan and with the tnloe o" nir column 9 which is carried by and projects upwardly within the receptacle 5. The

ll is :i stninei' oli' Suitable iinl which rents; on ton of teeenteole has n oentiel hollow sleeve l2 fitting snug' oveil the lionel' slightly tepeied month olf the tulle oiM conduit ll.
lil is a cover lttiingr the top of the filtert ll and inolosing with the filter the uppei' on 'passage-Way or clininhei ll.

ln operation the nii* from the suction tool, oi any number ot tools, zioooiding to the ce pneity of the machine, is admitted into the olnnnloei' 16 in. the ret-entente through the pipe i7; the lzittei' being preferably ouin/'ed :ind arming/fed so :is to discharge the nii olif euin'terentinlly against the eni'i'ed welll of ehziinliei lo whereby `the nii will swirl :iioiinil the Chamb/ei and. sillow the heavier solid pnitiolef; and refuse to settle in moet tee-.le Under the action of the funs the nii is then alinnn up thi'ongh filter ll into ohziinloer llnnd thence down the con duit 9 through the eje 'cl o tain 3; being diseh Uecl :it the peripheifitl outlet 1&3. Beand l is e partition :'20 on nieteen the loins o the lippe-i* side. ofwliieh une the stationary vaines 2l by which the nii clisolniigeil :it high i'elooitj,7 thiongh the outlet 18 isi directed nach the Central openin in plate it() n'heie it picked. up. -loy wle second -l and finally Clinolmigetl nt accelerated te loeity et into the inotoichamber 24 whence it io allowed to escape freely to the outer nti'nospheie; the (li-:itt ol" oir thi'ongh ehninhei E34.- .ffzetvingg to keep the nioto'f' 2 cool.
The ooinitinetion ol the liltei' ll while oft' any eni'tnhle 'tmin piei'Fei'nhly on'iboclies en nnnnlni' iiin 5 having; n downwardly pi'ojecting annnlni* flnne'e 2@ to teleeoope over the outside etlnje ol the receptacle 5; 'the fabric ot' the iltei' being' clamped between the i'ing iini 125 and :in underneath Ting; plate., which may loe of light sheet metal; suitable adhesive being;l employed to keep the E end together. The flange sleeve l@ is l `passed through a central 'hole in the filtering fabric and is glued or otherwise sui-tably secured thereto.
The motor'is preferably directly connected to the fansso as to run them at maximum velocity and I prefer a multi-stage fan or 4turbine construction for obvious practical reasons The method of` directing the air from the first fan to the second by means of the partition 20 and deiiectors Z1 is a very practical' and simple expedient. The orifice 7 in plate l6 which constitutes the inlet to the fan chambers has a cross area of such size that it will not allow more air to go through than the fans can handle without eventaxing the motor. In other words, in order to economize power a small motor is used to `drive a fan or-fans which' latter could it' ther'air inlet was uncontrolled, be so operated as to over-load the motor and burn it out. The size of this orifice is determined lby experiment and is a mere matter of engineering skill. l The chief feature of the present invention is the removable receptacle 5 and lter ll whereby all the disadvantages of theset-l tling bag are done away with.
The device as now constructed is very compact, of few parts and readily accessible. vManifestly various changes may be made in the details of vconstruction herein shown and described without departing from the invention. It is also manifest that any suitable type of suction inducing means may be employed.
I claim: l l. In a. vacuum cleaner, the combination of a casing inclosing a motor and suction apparatus, vand a removable receptacle fitting in the top of the casing and over the suction apparatus, said receptacle having a. central upwardly extending 4 air column opening throughA the bottom of the receptacle into the suction apparatus, a. cover, removable ilter medium between said 'cover and said receptacle encircling the column and inclosing with the receptacle an air inlet chamber, and a single means for locking the cover, receptacle and casing together,
and thereby clamp the filter medium in place, said chamber in the receptacle having an air inlet, said parts so constructed and arranged that on the operation of the motor air is drawn into the receptacle thence through the filtering medium and thence outwardly through the column into and through the suction apparatus.
f2. ln a vacuum cleaner, the combination of a casing inclosing a motor and suction apparatus, a removable receptacle fitting in the topof the casing over the suction apparatus, said receptacle having a central upwardly extending tube opening through the bottom of the receptacle into the suction apparatus, y
