Specification of Letters Patent.

Patented Sept. 4, 191 '7.

Application filed June 80, 1916. Serial No. 106,883.

To all whom it may concern:

Be it known that we, ALBERT E. PAINTER and lVA'rnnrmLn PAINTER, citizens of the United States, residing at Reno, in the county of VVashoe and State of Nevada,

have invented new and useful Improvements in Rotary Internal-Combustion Engines, of which the following is a specification.

This invention relates to rotary internal combustion engines, theobject in view being to produce a simple and compact engine employing in combination with a stationary member formed with, an annular combustion chamber and a segmental compression chamber, a rotary member arranged at one side of the stationary member and carrying laterally slidable abutments which operate within the compression and combustion chambers in such manner that the explosive mixture is compressed by being forced and transferred from the large central chamber of the stationary member through a pass into the combustion chamber in which it is ignited thereby expanding and driving the movable abutment ina circular path around and within the combustion chamber.

A further object of the invention is to' provide means to compensate for expansion of the metal parts whlch may occur when the engine becomes heated after continued operation and under adverse atmospheric conditions.

With the above and other objects in view,

" the invention consists in the novel construcsages.

Fig. 3 is a diametrical section through the engine.

Fig. 4: is a side elevation of the same.

Fig. 5 is a detail view illustrating the compensating means.

The main stationary and rotary parts of the engine are indicated respectively at 1 and 2, said members being substantially circular or disk-like and arranged side by side, the meeting faces of the

members

1 and 2 fitting closely togetheralong the line 3 in Fig. 3. The stationary member, or what may be termed the. casing of the englue, is provided with an enlarged supporting base 4. v

In. Fig. 1, which represents an inside face view of the stationary member or casing 1, it will be observed that said member is formed with an annular channel adjacent to the outer margin thereof constituting a combustion chamber 5. At the outer and inner sides of the combustion chamber 5,

the member 1 is formed with concentric-annular grooves 6 to receive packing rings 7 for the purpose of holding compression. Each of the rings 7 is preferably of the split resilient type. The rotary member or rotor 2 is likewise provided with annual concentric grooves. 8 to receive the opposite lateral portions of the same packing rings 7 when the two

members

1 and 2 are placed together in the relation illustrated in Fig. 3.

The stationary member 1 is also formed with a compression" chamber 9 substantially semi-circular as shown in Fig. 1 and terminating in inclines 10 which lead to and from an abutment retracting; surface 11 which is flush with the meeting face of the

sections

1 and 2. The stationary member 1 is provided at a suitable point in the length of the combustion chamber 5 with a stationary abutment 12 having an inclined surface upon which the power-abutment rides once in each revolution of the rotor or rotary member 2. 13 represents a spark plug entering the combustion chamber 5, and H the exhaust port which leads out through the periphery of the stationary member 1.

The rotor 2 is mounted transversely movable on a sliding key way 38 on the engine shaft 15, the latter beingfournaled in suitable bearings (not shown The shaft 15 also passes through a central opening 16 in the stationary member 1 and is formed with a longitudinal bore 17 for admitting the explosive mixture to the engine. A passage 18 leads from the bore of the shaft l5-to an chamber 5. It is to be understood that the meeting face of the rotor is flat or plane with the exception of the several ports just referred to and the guide ways 23 and 2% for the power abutment 25 and the compressing abutment 26, respectively, and concentric annular grooves S. The compressing abutment 26 is pressed into the compression chamber 9 of the stationary member 1 by means of one or more backing springs 27 and the power abutment 25 is pressed toward and into the combustion chamber 5 by means of one or more backing springs 28. The member 2 is formed with offset chambers 29 and 30 to admitwof the movement of the abutments 25 and 26 transversely with respect to the

members

1 and 2.

In order to provide for expansion in case of the heating of the engine, we employ the compensating means illustrated in detail in Fig. 5, wherein itwill be seen that the rotor 2 is' provided with a sliding key way allow- I ing rotor 2 to move transversely on shaft 15 and near the center of its outside face with a circular bearing face 3l. \Vorking incontact therewith 1s a thrust collar 32 which 15 pressed against the collar 31 by means of a, coiled expansion spring 33 interposed lie-- bear against the outer ,face of the collar 34.'

In case of excessive expansion of the metal parts due to heat, the rotor 2 is thus enabled to yield away from the stationary member 1 while at the same time the rings '7 hold compression, and suitable stufling material used where rotor 2 slides transversely on shaft 15 to prevent leakage at that point.

In order to supplyexplosive mixture to the engine, a stationary supply pipe 37 is connected to the outer end 'of the engine shaft 15 by means of a union 38 containing leakage at that point.

From the foregoing description, taken in connection with the accompanying draw ings, the operation of the engine willnow be understood to be as follows: The transsuitable stufiing material which will prevent versely slidable and spring-pressed abutment 26, in moving in its circular path,

passes from the surface 11 into one end of the compression chamber 9 thereby drawing in explosive mixture through the port 19, passage 18 and the bore 17 of the shaft 15. At the same time the charge of explosive mixture which was previously drawn in as just described and is ahead of the compression abutment 26, isforced thereby in the course of its rotation through port 21, passage 20 and port 22 into explosion chamber 5, and when port 21 is closed by passing from chamber 9 to surface 11, then or thereafter the mixture is exploded by spark at burned gases ahead of the power abutment 25 are forced outwardly through the exhaust port M by the scavenging action of said'powerabutment 25. The abutment 25 then rides upwardly on the inclined surface of the stationary abutment 12 and is a' ain pressed into the, combustion chamber 0 by the springs behind said. abutment. Thereformin each complete revolution of the enginc, the compressingabutment 26 moves throughmlt the entire length of thecompression chamber, drawing in one charge of mixture and forcing another charge into the combustion chamber, in the same revolution', the power abutment 25 makes one completecircuitbf the combustion chamber 5, being propelled bythe expansion of the explosive mixture and actingvto scavenge the burned gases in advance thereof. Any cooling and lubricating system'may be employed in connection with the engine, and it will also be understood that the parts hereinabove described constitute merely one power unit, it being perfectly feasible to employ as many of such power units as may be need-' ed in combination with a common engine shaft. F or example, two rotors may, be used in connection with a centrala interventhe engine already described on the reverse side of stationary member 1 on the same shaft, and in the event two rotors areused on stationary member 1 they oshduld be one-I half revolution ahead of each other, and compresslon chamber 9 of the second rotor wouldlbe opposite surface 11 of the first rotor, giving a continuous working explosion, and ,rotors balancing each other.

'lla-sc and other changes in the'forin, preportion and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.
