AER MOTOR.

afianza To @ZZ whom t may concern.'

Be it known that l, LOUIS VVESTIN, a citizen oit the United States, residing at Bangor, in thel county oli' Kitsap and State of Washington, have invented a lcertain new air motor ot balanced eonstru 'ctionl and'.mini-` mized friction that/,will generate power toA be utilized in driving a' 'dynamo or the like. VVlth the ladbove andv other ob3ects in view ceedsthe invention consists ofthe novel'con struction adaptation' .arrangement :and'icom bination of parts: hereinafter describedA 'and claimed.

, l accomplish `these objects bydevicesillustratedf 1n 'the accompanying I drawings,

whereine-A vention installed in the' .lower Fig. 2 ,is a'topplanview ofthe same;

Fig.'y 3 is a'view in longitudinal vertical section taken ona broken line-3,3 ot 2;: Fig. et is atop plan view of my air motor the upper half ofthe casing removed; and

Fig. 5 is a view in transverse vertical sec-` tion taken on broken line 5, 5 ot' Fig. 1.v

Referring to the drawings, throughout which like reference numerals designate like parts, the numeral 10 indicates the lower fragmentary end portion of a flue having a rectangular opening 11 therein.

Mounted within the lower end portion of said line 10 and partly projecting exteriorly thereof through said opening 11 isa housing comprising a lower base portion 'l2 removably superimposed upon which is an upper or cover portion 13. Said cover portion is retained in place by liolestherein fitting over dowel pins 14 secured within said base portion and said cover portion is held there-l 1t will thus be seen that the Cover portion 13 is adapted to be removed 'for the purpose of Y specification of Lefaers-lament.l Pawnee@ APE, M9 192g Application led February 26, 1921.A Serial No. 447,97*?.- j

cleaning the motor wheel more fully hereinafter described. v

rlhe top 16 ot the cover portion 13 is provided with an air intake 17 and an outlet opening, 18, said openings being separated by a partition 19 as shown in Figs. 2 and 3 of the drawings. i

Mounted within the cover portion 13 is the upper halt ot' a substantially cylindrical casing comprising a member 2O the upper. end ot'whi'chiis secured tothe outer wall oli' the opening 17, vand .aY member 21 the upper end or' which is secured tothe inner wall of the opening 18.

` The outer enos ort' thefrnembersv 20 and 21'` are"i seated within grooves: provided;v in 4the side walls of thecover portion 1.3 and their lower ends project slightly below the lower end offsaid cover portionas at 22.

Mounted 'within the baseportion 12. is the` f lower half 23 ot the cylindrical casing, the outer ,ends ofl which .are seatedy within grooves'V providedl in 'theside walls ofthe base portion 1-2 as at 24 and theupper ends y ,p Y y Y f 25 projectslightlyfabove the Vupperend.of

,Figure lfisfa view .inside elevation ot an'y air motor embodying the 'features oiimy inlllgmely said vbase4 portion 12'to'overlapthe ends 23 of th'eupper halt 'pol'fpfthel casingas s howninf .v Y i disc members 27 and 28 and forming a series of pockets 31 therebetween.

The end disc members 27 and 28 are keyed to a shaft 32which'is provided withreduced ends 33 and 34. rEhe reduced endsV 33 is rota'tively mounted in a. bearing` 35 securedto a bracket36 fixed to the base Aportion '12 and the reduced end 3-l-iis mounted in a bearing 37 secured. to the upper end ot' said base port-ion.

The cover member 13 is cut away as at 38 and 29, to prevent frictional contact of the shaft 32 and its reduced end 34 with said cover member and stops 40 are secured to the bracket 36 and base portion'12 to ,prevent thrust movementot said sha-tt.

The bracket 36 lis provided withan opening l1 and a pulley 42 is keyed tothe shaft namo or other mechanism (not shown) for the purpose of utilizing the power derived from the air motor.

Referring to the drawings, it will be seen'Y that the periphery of the motor Wheel 26 is y adapted to clear the lcylindrical casing and partition 19 in which it is concentricallyv mounted. The reduced ends 33 and 34 of Y the shaftBQ mounted in the bearings 35 and 37 formi "the .only frictional contact `between the rotary and stationary parts of the motor which friction is reduced to a minimum by virtue ofreducing said ends and bearings of said shaft.` Y

The partition 19isV adaptedto register Hush with the upper wall of the opening 11 in the flue l()V so that when the air motor is installed the intake opening 1,7 will be lo-l cated exteriorly and the Outletcpening 18,KV

lWill be located interiorly of'sa'id flue.

:and having "very little frictionalresistance will rrotate freely when given a slight ini tial"`impiilse and the draft of air drawn' in ings,

through? the opening 17 will strike said' mo `4 n 4t`o'i*`-"v`vl`1'eel tangentially. The ,impact of air Vagainst the vaines 30.* in its passage'jaround saidawheel and upwardly through the flue' lOby Way of the routlet opening "lvvill4 cause a.' continuous' v'rotary motion of: said Wheel which may be nutze-Ci ,in hammer specified/ vi i'- ,'Fromthe foregoing description taken in connection Vwith thev l accompanying Adraiv-y apparentto thoseA skilled in the art to `which now consider to be theY best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and suchchanges may be made When desired asl are Within the scope of my invention.

What I' claim is:

l. The combination with a flue, of an air motor comprising` a housing having an intake opening eXteriorly and an outlet openinginteriorly of said iiue, a motor Wheel rotativel'v mounted'ivitliin said housing, vanes 0n said motor Wheel,` and a substantially cylindrical casing extending from the outer Wall of said inlei-j opening around the periphery of said motor Wheel to the inner Wall of saidoutlet opening adapted to form a conduit for aircurrents passing around saidmotor Wheel in impactv with said varies.
