ROTARY ENGINE.

Application filed November 20, 1914.

7 '0 all whom it may concern:

Be it known that I, FRANK H. PARDON, a citizen of the United States, residing at Owensboro, in the county of Daviess and State of Kentucky, have invented a new and useful Rotary Engine, of which the following is a specificationj The present invention relatesto improvements in rotary engines, one object of the present invention, being the provision of a construction of engine, in which the active portion of the rotor is eccentric to the carrying portion thereof and by means of which the same is adapted to coijperate with an oscillatory abutment that engages at all times the periphery of the eccentric portion of the rotor.

A further object of the present invention, is the provision of means for causing consonant action between the parts so that the abutment is properly positioned at all times for directing the exhaust pressure fluid away from the engine, while the pressure fluid is admitted for expansive force at the opposite side thereof.

A still further object of the present invention, is the provision of a novel form of balancing means, by means of which the active portion of the rotor may beproperly balanced for high or low speed.

A still further object of. the invention, is

the provision of a rotary engine of exceedingly simple construction, and being composed of few parts the same is made more durable, efficient and practical in operation.

In the drawings Figure 1 is a longitudinal sectional view through the engine taken upon line 1-1of Fig. 3.

Fig. 2 is a top plan view of the complete engine. a

Fig. 3 is asection taken on line 33 of Fig. 1.

Fig. 4 is a perspective view of the eccentric strap and the connection with one of the abutments. i

Fig. 5 is a perspective view of one of the adjustable weights.-

Fig. 6 is a view similar to modified form of abutment.

Figs. 7 and 8 are detail views of the abutment per se.

Referring to the drawings, the numeral 1 Fig. 3, of a designates the chamber portion of the statorwhich has attached thereto, the respective heads 2 and 3, having their respective shaft Specification of Letters IPatent.

carrying members 4 and 5. The shaft 6 is journaled in the heads as illustrated, and as here shown is provided with the two active members 8 and 9 spaced by the cylindrical portion 10 therebetween. The active members 8 and 9 are eccentric to the chamber of the stator and also to the portion 10, and are oppositely disposed to produce the desired balance effect.

Each active member 8 and 9 is recessed as at 11 and provided with the radial bar 12 which receives the slot 13 of the adjustable weight 14,the bar 15 and set screw 16 being provided to permit of the proper assembling of the weight 14 and the adjustment thereof relatively to the bar 12. It has been pointed out hereinbefore that the parts 8 and 9 of the rotor are oppositely disposed, to produce the desired balance effect. It is not possible to secure a perfect balance in this way, although an approximate balance may be obtained. A perfect balance, however, may be brought, about by a proper shifting of the adjustable weights 14,radially of the rotor. 1 l

The pipe 17 is the fluid conducting pipe, such fluid being preferably steam, the same emptying into the bypass 18, which is c0mmon to both nozzles 01' jets 19 sothat the steam may be conducted to the respective active members 8 and 9 of the rotor at the angle as illustrated in Fig. 3.

There is formed in the stator 1 as illustrated in Fig. 3, one to each active member of the rotor, a chamber 20, which is provided with the inlet 21 and with the exhaust pipe 22 leading therefrom. The blade 35 of the pivoted abutment 34 as will presently appear is mounted for sliding movement through the port21 to engage the periphery of its respective active portions 8 and 9 of the rotor and thus prevent steam after entering through the nozzle or jet 19 from passing to the left a shown in Fig. 3, so that the expansive force of the steamwill be exerted upon the eccentrically disposed active member 8 or 9 to rotate the same in the direc-l tion of the arrow as indicated in Fig. 3, such pressure fluid being finally exhausted through the port 21, it being conducted thereto by the blade or abutment 35 when in the position as shown in Fig. 3. In Fig. 3 it will be understood that as the rotor turns, the exhaust steam is pocketed between the periphery of the portions 8 or 9, upon the one hand, and the Wall of the stator 1,

byfr'neans of the tapered pin 24. Surround ing the eccentric is the strap 25, there being interposed the antifrictional roller bearingflq to reduce the friction therebetween. Each strap 25; isprovided with the "p'itman 2'1 ,ivhich is operably connected by the pin 2 8 to one end of the rocking arm 29. The

opposite end of therocking arm is connected} to its respective rock shaft 30, which is journaled in th e stud 31 and is anti-fricuonauy' supported by the ball bearings 32, so that" the shaft 30 Will be operatedwith the least possible friction. Eixedup'onthe sh'aft 30f nfith in the 'respective chambers 20 of the statoi is the arm '34, Whiclicarries the abutment or blade 35 heretofore specifled, It vvillithiis b'fseen that" as the shaft fi iis rotatedj, the blade 35 Will be at all times maintained in "contact with the periphery of itsactive member Sor 9, and thusinsure a steam tightjoint at this point so that the exhaust steam Will be properly direct-ed into the "port '2Iandtl'1 r0uglrthfe chamber 20 to the exhaust pipe 22" As there ar'e two ciismterseo"; there are also two abutments 35 afidftwo' exhaust ports 21 and 22. i i
