VACUUM CLEANER.

APPLICATION FILED mm. 10, 1910.

Patented Spt. 3,19 12.

oFruo VACUUM-CLEANER.

To all whom it may concern:

" Be.it known that'I, EDGAR B. SriroNs, a

citizen of the United States, residing at Mllwa-ukee, in the county of Milwaukee and State of Wisconsin, have invented a cer ta1 n"new. and useful @Improvement 'in' Vamum-Cleaners, of Whichthe following is a specification.

My invention relates to improvements in vacuum cleaners and has for one object to provide pumping .mea'ns therefor, wherein a stream of water in the shape of'a spray or an attenuated stream inclosed in a pipe or fiow'ing through a contracted passageoperates or forms the pumping means an d at the. same time operates to take up and carry I of]? the debris collected, It is illustrated diagrannnatically in one form in the accomi fpanying drawing, Wherein' Figure 1 1s a part elevation andsectional view of a complete apparat-us; Fig. 2 is -a detail of the nozzle; Fig. 3 of the plug with} in the nozzle; Fig. 4 of the nozzle attachment device.

and A the usual v Like parts are indicatedby the same letter in all the figures; t

A is a sink, A a discharge'pipe therefrom water faucetof the water system. v I

'B is a suction tool adapted to be applied to a carpet or rug and. provided with a tubular handle B 1, the hose B which is connected with the lower end of a curved pipe B associated with a collar B. whence project the legs 13 B which with the lower curved portion of the pipe B form a stand. is a downwardly curved pipe, G a coupling adapted to be inserted in the head O of the pipe 0 and to ;be applied over the upper eiid of the pipe B O? is a body having a contracted pipe C at one end and ascrew threaded opening G at the other. Into this opening is inserted the water discharge nozzle D which is prei erably screw threaded'to the coupling piece D onto which the hose section D is slipped.

.Withi'n the noz zle I have placed means for imparting a spiral motion to the water, In

"the particular case illustrated, it consists-of a plug'D having thespiral grooves D D through which the water passes- The solid stream of water is indicated at D the small spiral discharge stream at D and the large or difiusedstream or sprayed mass of water i Specification 01' Letters Patent.

tion,-which is equal to that of the contracted pipe or passage 0*, at some point between The hose pipe D is adapted to beattached-to the nozzle A and in order tomake. this attachment easy and convenient the outwardly projecting flange. F of the funnel shaped flexible part F It is this latter part which is'slipped overthe end-of the faucet-and the parts are so arranged that the coupling is 'adapted to'vari'ous sizes of faucets. A

Any kind of apparatus'adapted for vacuum cleaning apparatus may be employed and I have alluded to the same simply as a suction tool, meaning by that term to include any such apparatus. By the term nozzle, 1'

,mean any suitable device for discharging in themanner suggested, a stream of water which Wlll issue in dltlused form and I have used the term contractor to indicate the ipe or passage Way into which or through w ich the diffused stream of water is thrown or forced.

It will be obvious that many of the parts shown could be greatly changed without departing from the spirit, of my invention. .1 therefore wish my drawings to be taken as diagrammatic and in describing the 'structure I do 'not wish to be understood as thereby limiting myself to the particular form shown.

I employ a stream which leaves the nozzle and expands into a stream of larger cross sectional area, which expansion maybe accompanied by at decrease in density, that is, the solidstream may break up into fine globular'particles-of water, each surrounded by air; The stream which enters the contractorv is perhaps made up of finely divided particles'of water carrying withthem a rel- 'atively larg: amount of .air which is replaced by in-rush of air through the suction pipe. f-' Y I claim u 1. An aspirator c'omprisin a closed a'ii' chamber, a conical nozzle disc arging therein along an axial line, a contracted discharge pipe leading from the end of said chamber removed from the nozzle and concentric with the nozzle, an air intake port leading to said air chamber at a pointremoved from said discharge pipe, means for dischar ing 'a whirling, conical, outwardly exten ing column of water from said nozzle through said chamber and into said discharge pipe, said means comprising a Water su ply plpe leading to thenozzle, and a plug coated at the base of the nozzle and between it and the supply pipe having a plurality of spiral grooves therein. i

' 2. A11 aspirator comprising a closed air chamber, a conical nozzle dischar ingtherein along an axialline, a contracte discharge pipe leading frdin the end of said chamber removed from the nozzle andconcentricwith the nozzle, an air intake port leading to said air chamber at a point removed'fro'm said discharge pipe, means for discharging a conical, difiused, gradually expanding stream of water which expands into and completely fills the discharge pipe but is of smaller cross-sectional area than the discharge pipe at the point where it leaves the chamber.

3. An aspirator comprising a closed air chamber, a conical nozzle discharging therein along an axial line, a contracted discharge pipe leading from the end of said chamber removed from the nozzle and concentric with the nozzle, an airintake port leading to said air chamber at a point removed from said discharge pipe, means for dischar ing a conical, diffused, gradually expan ing stream of water which expands into and .completely fills the discharge pipe But is of smaller cross-sectional area than the discharge pipe at the point Where it leaves the chamber, said means comprising a water supply pipe leading to the nozzle, and a plug- Witnesses:
