Application meld November 8, y11109. SerilNo. 5136,01()- To all whom 'it may concern? Be it known that l. CHARLES J. OLSON, citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Miohigen, haveinvented certain new and `useful Improvements .in Rotary Motors, of which the-following is a specification.

rIhis invention relates to. rotar)r motors und has for its object to provide a strong, durable, compact and -throughly eticient machine of this character, capable of being Opf erated by compressed air, steam, or other uotuating fluid, and which muy be used with equally good results for operating :L pneumatic drill, or as a niotorfor driving (litterent kinds of machinery.

A further object is to provide a rotary motor, the construction of which is such that the severaflfbarts thereof are evenly balanced, thus insuring a smooth continuous movement of the rotors, and consequentl)T increasing theeflioienov of the machine.

A still further object of the invention is generally to improve this class of devices so` as to increase their utility, durability. ond

Further objects and advantages will appear in the descrii'ition, it being. understood thetvariousv changes in form, proportions and minor details of construction may be resorted to within the scope of the appended olziims.

For a full understanding of the invention )reference is to be'had to the followingl Figure 1.- ,is a persnective v'iewiof o ro'tary transverse section xil-viewftelten on' theyline 343 of Fig.` Zand looking 1n vthe' direction c 4iso. .similar-.view .teken on -thelnie .11s-4o Fig. 2 'and looking .in\ the directio'xrof the arrow. -I'Fig is fan e117' .I arged detail sec-tional view of al'portion of 'the cesing.

The improved motor forming thesubjectmatter ot the present invention comprises o. casing or housing 5 preferably' substuniially cylindrical in sha e, andl formed'ot a plurality, of indepe ent sections 6 yheld in assembled position by tie-rods or bolts .7 piero ing the opposite heads 8 and 9 of the easing.

Interposed between the casing sections 6 are a plurality of transverse partitions 10 defining intermediate compartncnts 11 in which are mounted for rotation a plurality of rot-ors 12, the latter bei-ng keyed o r otherwise fixed to a centrally disposed driving shaft 13.

The Casin or housin. 5 is provided with oppositely isposed enlargements .14; each plerced by an `.nlet port 15 and exhsustp'ort 16, there being auxiliary ports 17 formed in suitable turning plugs 52' threaded in the easing sections. and through 'which compressedl air or other actuating fluid is ad- .mitted to the compartments 11. Auxiliary port-s 18 are formed in the casing sections to permit the/passage of the exhaust stezun from the compartments 11 to the ports 16 and thence through the opening -or port 18' to the atmosphere.

The rotors 12 a'r'e preferably of irregular shape and are 'each provided with peripheral .recesses 19 in which ,are pvotolly mounted at 20- blades or pistons 21', there being aishoulder 22 formed by one wall of eachirecess 19 furthe purpose of limiting the swing ing inox-'ement of the adjacent piston. The pistonsfl are normally and lyieldebly sup.-

One wall of each of the recesses 2B is inclined or beveled in suoli a manner as to produce a stop shoulder 31 adapted to receive the impact of the adjacent abutment thereof, there beingsutable coi springsBQ seated vin sockets formed in the enlargements 1 4, and bearing against the' adjacentabutinentsO for normally 'and yieldablysupporting the active ends ofsaid abutments movement of the rotors 12.

Attention is here 'called to the fact that the inner wall of each enlargement-1.4 is provided with an irregular or cam face 33 which by' engagement with the/active ends ofthe swinging blades or pistons 21 serve to gradually close the latter and thus'preyent injury to-tbe'same by reason of a sudden jar or vibration, which would naturally result if the pistons or blades 21 were closed abruptly. The projecting'portrions 34 ofthe rotors perform the-same function with reference to tbe swinging blades or abntments to cause the gradualclos ing of said abutments when the members 12 are rotated.

The rotors 12 are to the driving sha slight movement of one relative to the othert and Vthus preventbinding or wedgingaction between the parts.

Then 'the motor'is employed for operat- 'ing,' the bit of a pneumatic drill, an inlet piped?)A is preferably extendedacross the head 8 ofthe cesing and operatively connected 'hvith the inlet ports 15 so as tb forni in `effect a 'handle by means lof which the device may be referably loosely keyed A supply pipe 36 communicates with une end' of-thc inlet with i-turning plug af similar valve 37 means of whicbthe supplyocompresse air to tlie''compartments .11; may

The cy'lindrical enlarge- -ment 41 .ofthe spindle39 is provided with an annular lip or flange 59. spaced from. the head or closure 51 to form an intermediate chamber or compartment for the reception of packing 53, there being anti-friction balls ieee 49v is preferably secured to the or rollers 54 interposed between the flange 521and the adjacent portion of the cap 49 for the purpose of reducing friction between arts.

T us it will be seen that when! the cock or valve 37 is opened, air .under pressure will pass through the-"inlet ports. 1.5 and nie'nts 411, and being confined between the pistons 21'and abutmeits 30 will rotate the 12 in the direction indicated by the arrow in Fig. 3 of the" drawings, vthe compressed air being' exhausted vthrough the ports 16 and 1'8 `in the 'manner before described.
