TocZ-Z'who'm it may concern;

Be 1t known that we, TnEoDoRE WIEDE- MANN and. JOSEPH H. TEM-PLI-N, citizens` of th'efUnited States, residing in the city and countyof Philadelphia, State of Pennsylvania, have invented a' new` and useful Vacuum-Cleaner, of which the following is .a s ecilication.

ur invention consists of a novel construction of a vacuumoleaner and our Ob- ]ect Isto provide Ya' simple inexpensive and Y effective machine7 which is compact and readily portable and takes upbut a minimum amount of space, provision beingmade for Vactuating the' principal operativev parts .ofthe device by means of an electr1o or Ve employ a removable tray, a 'separating deviceV for vthe dust and air above the tray and a rotarybrush located in proximity to and beneath said separating device jand guided substantially parallel 1 therewith v and a vacuum .,pumpingfdevice operated by said motor and disposed above the separat- 'lng device. y

For the purposeof illustrating our invenf tion, vwe have shown-in the accompanying means of which the air commingled with.

drawings one form thereof which is at pres-l ent pre erred by'us, since the same has been Vfound in practice to give satisfactory and .reliable resultsfalthough it lis to be understood that the various instrumentalities of which our invention consists canbe vari-V ously arranged and organized and that our" invention' is lnot limited to.' vtheyprecise ar# `rangement and organization of these instrumentalities as herein shown and described.

' Figure l represents a vertical sectional view partly in elevation .of a vacuum cleaner 40 our invention. Fig. 2 repreembodyin ge elevation of the observation desents a si viceseen at the right liandof Fig. 1. Fig.

3 represents a section on line .a2-, Fig. 1. Fig. 4 represents on a reduced scale,'a diagrammatic view of the apparatus showing themanner of using the same.

Similar numerals of ,reference indicate corresponding parts in the figures.

Referring to thedrawings: 1 designates the vbase of the 'apparatus upon which is supported the removable draweroi' tray `2 above which is located the inlet pipe 3 by the dust, dirt, etc, is conveyed into the ap- Speeication of Letters Patent. Patnted Nov. 2,1909; Application inea march 10,1908. serial No. 420,174.

leadsinto 'the observationl device 5. The observation device 5' consists of the heads 6,

casing of glass-for other transparent ina-y terial 7, as will'be understood fromy Fig. "2,

the above parts being held in assembled'poparatus from the suction pipe 4 whichlatte'" sition by means of therod or other fasten-l 'ing device 8. The commingled air and dust,

dirt and other impurities is` initially received in the' dust chamber 9 above which located the dust separator or screen .-10

which` may be composed of cloth, canvas,

wire gauze or other suitable material'and below said screen is located the cleaning 'device llfwhich in its' simplest form may be a rotary or other brush supported upon the rod or rods 12 which may beiguided inthe wall 13, the outer extremity of the said rod being provided with an eye or handle 14 whereby the brush or other cleaning device 11 can be rea ily reoiprocated along the underside of the screen 10 for the purpose ofcleaning the lsame according to requirements. Y

15 designates the base or bed of the vacuumvpumping apparatus whichfis preierably supported upon the walls 13 and provided with the outlets 42 leading'to the atmosphere, said bed 15 supporting the outer casing 17 which incloses the motor 18 and its adjuncts. The motgr 18 is provided with the Inain-` shaft 19 to which are secured the crank disks2'0 each of the latter having the crank pins 21upon'which are mounte the upper ends of the connecting rods 22, Whose lower ends terminate in the heads or lianges 23 between which and the rings or plates 24 are held the diaphragme V25', the

construction shown in the present instance appearing as one continuous strip of leather or other` suitable material which is held in position at" itsy extremities. between the i les Y Itwi 36 designates the discharge valves, eachv of which is secured against the flange 37 by l means of the screws or otherfastening devices 38 which pass through the lates 39 it A being apparent that eachof sai discharve valves controls the ports 40 and normally rests upon the valve seat 41 whereby when the device is in operation the air is dis- :charged through the ports 40 into the outof electric energy may Y which lour device is used, it being apparent that the hose 4 is connected to a suitable brush or nozzle 44 and provided with a. suitable handle 45 for thepurpose of directing or appl ing the nozzle to any desired point.

ll be a parentto those skilled 1n the art that o'u'r evice is especially applicable for removing dust or dirt from surfaces such as ioors, walls, ceilings of dwelling houses, Mice-buildings, factories and warehouses, bookcases and -shelves and books or removing-dust from ob'ects or a-rticles as carpets, rugs, furniture, c othing, passenger coaches,

sleepinV cars, drawing room cars and the like an that by our invention we have produced anapparatus by which the cleaning or `removing ofdust may be accomplished in an effective and rapid manner withl ease and despatch rand we are enabled to practi' H,cally clean any suitable surface, ob]ect or r 'larticle froxnevery adhering or ,dirt which can be remove particle of dust In ythe -construction shown in Fig. 4 we l have shown the manner in which ourappearatus can be practically used and it will apparent that in lieu of the handle 45 we ma employ an elongated handle if desired an it will, be also apparent thatwhile we have shown a iiap valve employed as the suction andl dischar e valve, other forms of` valves may be emp oyed if desired.

The casing sections 15 and 17 may be vcast in a single casting if desired and the in otor 18.1'nay be supported by different devices thanthat shown. In the preferred manner of assembling the cleaning device I 11 we have shown the same as mounted upon the bearing? Y supported or trunnions 46 which may be the oppositely located ooves 4'( but it wi l be apparent that the c eaning devicemlilavghich maybe a rotary or other brush may be' supported in various other ways than that shownawithout vdeparting from the spirit of our inventipn.

It will be apparent that while in our present invention suction is utilized so that the dust-or dirt is sucked into the apparatus and entirely removed from the compartmentA or. room inwhich the dust was originally, `we do notA desire to; be restricted infevery instance to the exact constructionffwe" have herein shown and described but reserveto.

ourselves the right to make all such changes as will come within the scope and spirit of our invention.
