Beit known that I, CHRISTIAN NUIIANN, a citizeny ofthe United States, residing at St.

Louis, inthe State of Missouri, have invented v certain new and useful Improvements in Pressure-Blowers, of which theifollowin is a s peciiication, reference being had therein to vthe accompanying drawings.

` This invention relates to improvementsl in i This invention consists of a revolving menu ber within a casin for creating a ra'pid cur'-` rent of air to be distributed through tubing vto any point.

, The lobj ect of this invention is" to provide a revolvin member with passalges terminating outward y from the axis, co ecting air and,l delivering it under pressure through said passages into a chamber formed i'n the casing of the blower, from whence it is distributed.l

" Figure y1 is a verticallongitudinal sectional view takenv on the line 1 l'of Fig. 2 viewing v in the direction indicated by the arrow. Fig.v 2 is a vertical cross-sectional view taken ony the line 2 2 of Fig-L lviewing in the direction indicated by'the `arrow. Fig. 3 is adetail.

Anair-receiving chamberS In the construction og the device as shnwn I provide an criteri-'casing 4, comprisingr two vertical walls 5 and 6, Veach havlng central openings 7, through which the air is admitted is formed inthe casing', 4 bythe outer periphf ery 9 and 'the divisions 10, 1;:1'; and 12. 'Passages 13 are formed between the overla ping ends of the divisions, through whichjt e air under pressure is dischar ed' into .the air-reeiving chamber 8 from t and gradua ly increasing in size, terminating tached. i

bearing 16, held in the center of the'2 openings Aarms 17. In these bearings is support'-V ofa disk 20,l rim 21, an outer casting 22,

Theair-receivin chamber is constructed fin the form of a he ix, beginning with a nar-l row openin as indicated by the numeral 14.-,v

l drivingshaft 18, upon whichis rigidlyVv untedthe, revolving member 19, 4consist-- rim are vformed integral, and to said rim is fastened in any* suita ble manner the castings 22 and 23'. The rim 21 has'a plurality of openings or slots 24. Also passages 25v are formed in the outer casting 22 in -alinement with the slots 24, forming an outlet -through which the air is passed from the center ofthe revolving member to the chamber 8.* I

The outer corners of the passages 25 are curved, as. indicated by the numeral 26.

This is for the purpose ofdeflecting the air as it passes Jfrom the passages 25 in the direc-iv -surface of. the passages, then outwardly through the lsaid vassages'and into thel spaces between the revo ving member and divisions. The air in these spaces is forced out int/o the vair-receiving chamber 8"by the corners of the revolving member by yway of the passages 13;

Qn each side of the rim 21 and extending downwardly a shortv distance beyond the lowest edge ofthe inner castings 23 is a ring 30, which Vhas a tendency to retain the air from, passing sidewise and lodging between the revolving member' and wal s ofthe cast will be observed that the spaces between lthe divisions and periphery of thecasing formingl the receiving-chamber yincrease in size from al quarter to a half, from ahalf to three-quarters, `irom `three- .1uarters to a whole, the expressionl quartef indicating its starting-point, and whole indicating its outlet or discharge end.

The revolving` member is 4operated in the direction indicated by the arrow 2, the air being `admitted through'the central'ope'nings 7 in the lwalls 5 and 6. The air coming into. f The walls: 5 andj are each provided witha the rapidly-revolving lmemberl is agitated, said air-.having a tendency to move toward'v IOC' The operation of my inventionv is as follows:

` the eriphery and coming in contact with the su aces 28 giving it a movement as indim cated bythe arrows 3. y The current of air then comes-in contact `with the ends 27 ani is then deflected outwardly through the I it) sages 25. The outlets'of the passages 25 are smaller than the, remaining portion, and by this construction a pressure is created. The air at this point being under pressure ajourrent lis formed traveling a course as indicated by the arrows 4 and then discharged through the passages 13 yinto the receivin -chamber 8, Where in this instance the air wi l take the course as indicated by the arrows 5 and then out through the outlet 15. --v

' Having fully described my invention, what I claim is- A blower of the class described comprising an outer casing7 divisions located in said cas- 'i 5 ing, dividing said casing into two chambers,

the ends of said divisions overlapping, forming passages for the air, a revolvingmember secured to the inner and outer sides of said rim and provided with openings through which the air may pass, substantially as specified.

In testimony whereof I ,hereunto set my hand this 19th day of January, 1905.
