B i known that 1, CHARLES F. simmer, a citizen of the United States, residingat Bridgeport, in the county of- Fairfield and State of Connecticut, have'inven'ted certain I new 1 and use'ful Improvements; in Portable Vacuum-Cleaners; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, suchlas will enable. which" it appere Etains to make and-use the same. l

others skilled in the artto My invention relates to vacuum cleaners, suchas' are used for removing dust and other foreign substances from 'carpets, rugs, 'furni-' ture, and the like,-., buttmorearticularly has reference to ri'utc hine s of }t is description which may be readily moved about and di-* rected by the hands; of the operator and which therefore'may be classed as portable vacuum cleaners. V a w The object-of my improvement is .to provide a simplemachine of this nature, economical as to cost and readily operated. With these ends in'view' my invention con-; sists in the construction .and arrangement ofparts hereinafter fullydescribed and then particularly pointed out in the claims which air-Eig. 4 a section at the line x, :12, of- Fig. 3, and Fig. 5 adetail-bottom view of the nozzle,

conclude this description.

In theaccompanying drawing Figure is aside elevation of my improvementFig. 2a

Plan view-r Fig. 3 a detail sectional elevation of the chamber for separating the .dust and Similar numeralsof reference denote like In machines of this description an air pump is employed for creating. a suction through the net removing pipe and nozzle, whereby the dust or other foreign substance is abstracted from carpets, rugs, furniture and the like, and drawn within a chamber:

where the dust &c., is separated l IOIII the air, the dust or ptherrefuse falling by gravity to.

the bottom of said chamben while the air, after purificatiohpis drawn into the pump and then discharged through-suitable valves into the atmosphere.

My improvement has nothing to do with the pump itself since I can use any ordinary suctlon 1pump, and therefore I have not illustrated t e internal construction of the pump but have merely shown the, hand operating lever connected to the piston of a pump so that when said lever is operated, the piston will be reciprocated to create anair suction.

My machine is directed all over a'room, 2

and simultaneously operated by direct and positive instrumentalities, by a single person,

the dust removing nozzle bein at all times in'o eration, all of which will e clear from the ollowing description.

-;1 is a-platform or truck provided with .oppositely disposed casters 2, 3, and 4is a suction pipe supported on said truck and having an extension 5 at the free end of whichlatter is a nozzle Shaving an extension 7. At the bottoms of this'nozzle 6 and section 7 are coincidingelongated slots 8, 9, which constitute'the mouth of the nozzle, the object of the telescoping feature being to enable the slot of-the nozzle to be contracted more or lessthereb intensifying the suction to a greater or esserdegree, as may be desired,

all of which will be more clearly understood by the description hereafter to follow. This nozzle is deflected downwardly from the lane of the section 5 so as to be on the same orizontal lane with the tread of the casters 2, 3, and t erefore it will be clearly understood that the truck 1 has three points of support, namely the casters and the nozzle. 10 is any suitable vacuum creating pump supported on the truck in any ordinary man ner and provided. with an actuating, piston to any suitable block 13 rising from the truck and o eratively connected to the piston 11, where y outwardly and inwardly swinging motions of said lever will actuate the iston ando erate the pump. I prefer to ma e the hand e 14 ofthis lever separate from the latter and to secure them together by means ot a set screw 15 so that their angular (llSPOSl- "tionwith'respect to each other may be changed to suit the convenience ofthe o 'erator, but of course the lever and ban e ,may be made'mtegral if desired.

16 is the separating chamber where the air is freed from the particles of dust or other fore matter, which chamber rests by its gravity upon the truck-1. 17 is the cover of this chamber,v which cover is preferably dome shaped so as to provide a space 18 within the same. I

1 9, 20, are nipples communicating respectively with the cover 17 and pump 10, and 21 is a rubber hose or other flexible tube connecting said nipples, so that it will be clearl understood that said nipples and hose orm a continuous connection between said pump and cover.

11, and 12 is a lever hinged at its lower end 22 is a metal frame suitably secured to the truck 1 and extending immediately above the cover 17 and to this frame is pivoted a cam lever 23 which is. operated directly against the nip le 19 so as to bind the cover 17 tightly to tie chamber 16 and thereby hold the latter in position upon the truck;

1 24 is a handle which is secured to the 3 frame 22 preferably by means of a set screw 25 so that said handle may have an angular adjustment to suit the operator.

- the mouth or lower part of this ring 28 is dle 30 any suitable perforate material which, in the drawing, is ilustrated in the form of a rid- 31 are screens one above the other, the frames 32 of whichscreens are supported by the flange 27 and closely fit against the inner wall of the chamber 16. l/Vithin' the ring 28 and between the riddle 30 and the lowermost screen 31, are preferably laced pieces of cloth, waste, orother suita lematerial (not shown) and within the dome-like cover 17 is preferably placed any suitable de-odorizing or disinfecting material (not shown);

33 is a nip le suitably secured to the outside of the c amber 16 and, terminating at its inner end in a nozzle 34 which extends Within the chamber 16 substantially tangential to the outer erimeter of the ring and directed immediate y beneath the flange 27 toward the blades '26. 35 is likewise a nipple secured within one end of a suitable union 36, the suction ipe 4 being secured within the other end of said union.

37 is a flexible hose secured to the hi ples 33, 35, so asto connect the same, whereby it will be clearly understood that a continuous passa e will be provided from the nozzle 6 into t e separating chamber and thence out through the cover thereof into the pump.

The operation of my improvement is as follows :In the first place, the operator adj11sts the handles 14,24, to suit his convenience, and then, utilizing the rigid handle 24, hepropels the cleaner in any desired direction, and this is rendered very simple by reason of the fact that I have roviided three points of support, two of whic 1 are the casters above noted while the third is the nozzle itself, and this arrangement I believe to be entirely novel and it contributes greatly to the ease and practicability with which my improvement .may be managed by a single person. As the o erator propels the device he simultaneous y swings the crampe handle 14 inwardly and outwardly thereby operating the pum v r The device may e tilted or lifted at either end in order to pass over obstructions, and in order to conveniently operate beneath heavy articles of furniture the telescoping section 5 within the pipe 4 may be extended more or less, as may be desired, and also the nozzle itself may be contracted .or extended as above set forth, in order to intensify or weaken the suction produced by the pump.

As the air laden with dust and other for-' eign particles is sucked by the action of the pump through the passage formed by the pipe 4, union 36, nipples 33, 35, and hose 37, it will be driven Within the annular space between the chamber '16 and ring 28 against the blades 26 and a whirling action will thus be imparted to the air and dirt. The greater part of the dirt or other foreign material being arrested in its s eed, owing to impingement against said b ades, will become pockmains in the air, will be deposited upon thev Waste, cloth or other material contained within the ring, and the continued passage of the air through the series of screens 31 will com letely free it from foreign matter, while the eodorizing ordisinfecting agents within the cover will relieve the air of any bad charged into the atmosphere under the most sanitary conditions Of course it will be understood that the presence of deodorizing or disinfecting agents is not essential to the successful operation of my improvement, and it will llkewise be clear that I can utilize any desired number of screens 31 and thus do away with the advisability of utilizing anydust catching material Within the ring 28.v

By throwing up the cam lever 23 and removing the flexible connections 21, 37, the separating chamber 16 may be removed from the truck so that the dirt and dust therein may be dumpedand'the screens and other dust catching material thoroughly cleaned. In operating my im rovement within.

places the hand es 14, 24, may be adjusted to a vertical position or tosuch other position as may be found necessary, or such handles may be folded forwardly, as is shown in the instance of the handle 14 at Fig. 3, this folded position of the handles be mg very convement when the apparatus 105 i odors and will purify it so that it will be disrest the current of dust laden air, and therefore any suitable appliances of this description may be employed, or, these blades may be fastened directly to thering itself and the latter would be secured in any suitable manner within thewhamber, since it is merely necessary that the blades or other baflle plate devices shall be located in the s ace between this ring and-the wall oi t e dust erierating chamber, avingthus described my invention what I claim 'as new and desire to secure by Letters Patent is:-

1. A portable vacuum cleaner, comprising a truck, a pum and dust chamber carried'by said truck, a pipe connectingsaid pump and chamber, a suct10n pipe carried by said truck jand'leading into said dust chamber, a suction nozzle connected to the free endof said pipe, and two handles carried by said truck and said pump one of which handles is rigid with the truck while the other is operatively connected with the pump.

2. A portable vacuum cleaner, comprising a a truck supported near its rear end by oppositely dis osed casters, a pump and dust separating c amber carried by said truck, a pipe which connects said pum and chamber, a suction pipe carried by said truck and leading into said chamber, a-suction nozzle con nected to the free end of said pipe and depending below the plane of the truck and constituting the forward support of the latter, and suitable handles carried by said truck and said pump whereby the truck may be' i'propelled and the pum operated.

3. A ortable vacuum 0 eaner, comprising the truc l; having three points of support two of which are casters beneath opposite sides of the rear portion of the truck while the third is the vacuum suction nozzle itself beyond the forward portion of the truck, a ump and a dust separating chamber carried by said truck, tubular connections between said nozzle, chamber and ump, and the two handles one of which is rlgid with the truck while the other is operatively connected with said pum I,

In testlmony whereof I 'affix my signature in presence of two witnesses.
