To all whom t may concern.'

-Beit known that I, WALTER G. MACoM- BER a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Muliier, of which the followin is a specification;V

his invention relates to improvements in muiilers for rotary internal combustion en' gines of thetype shown inU my prior Patents Nos. 933,316, September 7, 1909, and 1,042,018, AOctober 22, 1912, and is a divisional application of my pending appli- `sectional view of the muflier showing cation Serlal N o. 24,916, filed April 27, 1915, the primary object being to rovide a rotary muller which will provide or an effective air cooling of the motor and a thorough exhausting of the spent gases from the motor cylinders as well as the mufHi-ng of the noisesof the explosions.

An object of this invention is to provide a muier of the character vdescribed which will effectively mums the noises of the explosions without retarding the motor actlon to an appreciable extent and which may be simply and cheaply'constructed.

Other objects and advantages will appear from the subjoined detail description.

The accompanying drawings illustrate the invention. y f

Figure 1 is a top 4plan view of the engine equipped with my improved muliier showing parts broken away and 1n sectlon;

Fig. 2 is a cross sectional view taken on line v2--2of Fig.-1;

lFig. 3 is an enlarged fragmentary detlil t e manner of connectingv the exhaust tubes therewith; and

Fig. 4 is a fragmentary vertical sectional view of the mumer showing the exhaust port thereof. y

Referring to the drawings by characters of reference, A designates a rotary engine which includes a casing 1, a frusto-conical air intake funnel 2 connected at its smaller end with one side of the casingand a series of exhaust valves 3.- In the drawings there is shown one of the exhaust valves and part of one of the engine. cylinders 4. Each of the valves communicates with a chamber` and which sucks the air through the funnel 2. A

` The casing 1 at the sideopposite to the funnel 2 is provided with an enlarged cir'- cular mulier casing 7 through which prol jects the shaft 8 of the motor A, a bearing 9 being carried ,by and projecting from the casing so as to'receivethe'shaft 8.

Rotatably mounted upon the shaft 8 within the casing 7 is a muffler designated 10 as an entirety which is circular and comprises a frusto-conieal circular body plate 11 rotatably mounted upon the bearing 9, a rotatable bearing 12 being interposed between the plate l1 and bearing 9. The plate 11 is provided with av peripheral attaching flange 13 whichv is secured to Hanges 14 on the revolving cylinders of the engine A by bolts 15 so as to provide for the rotation of the muiiier with the cylinders.

Securedv upon the other face of the peripheral attaching flange 13 is a channel shaped muier ring It-of considerably less diameterthan the casing 7. An inwardly extending annular ange 17 is carried by the ring 16 and abuts the attachin Han c 13, the: bolts 15 being, passed throng 1.

threaded openings to receive the,v screwthreaded ends of the bolts.

Radially mounted within the .ring 16 are segmental muiiier plates 18 'which are -se the. angesv 14 and 17, and the flanges 14 have screwv in the outer wall ofthe casing 7 The exhaust tubes 6- are extended into the casing 7 and are connected'lwiththe exhaust ring 16 as at 21, openings 22 being probv vided inthe exhaust ring to communicate the latter with the exhaust tubes.v The casing 7 has upon its inner walll a circular opening 23 through which the tubes 6 pass, said opening beings'ufiicientlylarge to provide for the passage .of air from the casing 1 into the casing 7 at points surrounding the tubes 6.

The peripheral Wall of the ring 16 is pro- I videdat spaced points with outlet orifices 24 vfrom the motor cylinders and muffler.

and extending outwardly7 from said peripheral wall are parallel fan blade-supporting flanges 25 between and secured to which are spaced transverse fan blades 26 which are slightly curved in cross section.

The muffler plates 18 form series of circular compartments exhaust ring 16, and to provide for communication of the passages with each other, there are formed in each muffler -plate a series of orifices 27.

'Ihe operation of the muffler is as follows: When the motor A is operated, the exhaust valves 3 allow the -exhaust gases to pass through the tubes 6 into the muffler ring 16 of the muffler 10. The exhaust gases in the muffler pass from one compartmentto another and out throughthe orifices 24. rIhe muffler 10 rotates With thev engine and the fan blades 26carried on the periphery of the mufiier produce a suction within the cas-A ings 7 and 1 and causes-air to be drawn through the lfunnel 2, which communicates with the atmosphere, and' into the casing 1 about the motor, thus cooling the motor. An

"exhaust pipe 28 communicates with the lower end of the casing 7 and the air which has been drawn through the casing 1 is exhausted through said pipe together with the exhaust gases which escape from the muffler lthrough the exhaust orifices 24. The fan blades 26 blow the airvand gases out through'the pipe 28. The rapid exhaust of the air through the casingv 7 causes the ex- 'haust gases Within the ring 16 to be sucked through the exhaust orifices 24 and results ing surrounding the engine and having commumcation with the atmosphere, of a or passages Within thel -haust gases out rotary muffier operatively associated with the engine,v.,a casing for the muffler communicating withthe-engine casing and having an exhaust, and fan blades carried by the mufiier to'produce a draft of air through the engine and muffler casing.
