Specification of Letters Patent.
Patented Dec. 11,1917.
Application filed March 31, 1914. Serial No. 828,536.
To all whom it may concern:
Be it known that I, LOUIS S. Momus, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Internal-Combustion Engine, of which the followin is a specification.
My intention re ates to internal combustion engines of the rotary or turbine type where here is provided a rotor carrying sliding pistons, which, acting in conjunctron with the stator, will suck the 'explm sive mixture into the engine, compress it to the extent desired, and, on the explosion of the compressed mixture, the rotor will be operated to scavenge the chamber and suck in and compress new charges.
My object is to produce an internal combustion engine of the rotary or turbine type which will be simple in construction, highly efficient in service and of great power relatively to the fuel consumption.
These and further objects will appear from the following specification and accompanying drawings taken together or scparately.
My invention is illustrated in the drawmgs in which the same parts are designated by similar. reference characters in all the figures.
Figure 1 represents a half longitudinal section and half side elevz'ttion of my i1nproved engine showing the parts in position immediately prior to the explosion, and suction periods, and nearing the ends of the compressing and scavenging periods.
Fig. 2 is a similar View showing theparts in osition for firing, suction, compressing and scavenging.
Fig. 3 is a sectional view on the line 3-.--3 of Flg. 1.
Fig. 4 is a sectional view on the line 4-4 of Flg. 1.
Fig. 5 is an elevation of a portion of a cheek plate, and
Fig. 6 is a side elevation partly in section of a modification.
A stationary casing or stator 1 is'provided and this casing may be firmly secured to a suitable floor or foundation (not shown), and the casing is provided'vvith suitable bearin 2-2 which support the shaft 3. These fiarings are carried in side plates 4. The side plates, at their peripheries are rigidl secured to. an annulus 5. The annulus and the side plates together form the stator of the engine. The annulus and the side plates are suitably Water jacketed to prevent excessive heat, as is well known;
The bore of the annulus is not cylindrical in its entirety but is formed of aseries of semidunes a, b, c and d, with short cylin- While I have shown the In the embodiment illustrated I show a pair of oppositely disposed transfer valves 10, 10 and these valves are. shown as 90 from the inlet valves.
Carried on the shaft 3 is a rotor 11 which, in the embodiment illustrated, will serve as a fly wheel, and carried bythe rotor is a plurality of piston slides, e, f, g, k, i, j, k, and Z evenly spaced around said rotor.
' On the inner face of each side plate 4; is a recess 12 and in eachrecess is seated a cheek ring 13. These cheek rings bear against the sides of the rotor at its peripheral edge and are made of hardened material to prevent wear at this point.
of radial slots it which extend inward from the periphery and each crunniunicates with a pocket'lt These slots and pockets extend from side to side of the rotor 11. In each slot is carried a piston slide and each slide is provided at its inner end with a shoulder 16, and between each shoulder and a. wear plate 17 at the base of each pocket 15 is a spring 18 tending to force the piston slide outward. ton slide is provided with a semi cylindrical groove into which is fitted a correspondingly shaped wear block 19. The outer face of the block 19 is of the same curvature as the bore of the annulus 5. Carried in each slot 14 and forming wearing surfaces for the. slide pi ton therein is a pair of tapered plates 20 of case hardened metal. Each plate is held in place by a key 21 and the key way in the plate is made larger than its key so that when the piston is moved outward it will carry the plates with it more or less and binding will be prevented. When The outer face of each pisthe pistons are in their outermost positions the gas is not under pressure and th re will be no tendency for to leak past the plates 20 during compression for the reason that as the piston is immediately started inward and carries the plateswith it, thus nmking a tight joint between the plates and the sides ofthe slot, and the plates and the piston. As soon as the explosion occurs the piston startsto move inward. When the piston is returned the plate will be brought back with it and onaccount'of its edge shape, will closely grasp the piston and prevent leakage at this point.
In each cylindrical part 6 of the bore of the annulus is inserted a hardened wear strip 25 to prevent leakage at this point.-
The inlet valves 9 are identical and a description of one will sufiice for both. The valves extend the entire width of the rotor and are carried in housings 23, 23 formed integrally with the annulus 5. comprises a block having a passage 24 which communicates with the inlet port 7 on one side and .with a lune shaped compression space on the other side when the valve is in its innermost position. The outer side of the block is provided with a cylindrical-extension-25 and surrounding this extension and interposed between the block and the cap of. thehousing isa spring 26 which lends to normally seat the block in engagement with the periphery of the rotor. In the cylindrical extension 25 is a piston 27 carried on an adjusting screw 28 and. the wall of the extension is provided with a series of perform tions for admitting air or other fluid to the cylinder below the piston.
The transfer valves are identical in every respect with the inlet valves except that in gddition to the openings for the passage of he gas, the block contains a cavity 29 for holding a charge of compressed gas.
The annulus is provided with lugs 30 and the side plates have similar shaped lugs 31 and bolts 32 are passed through these lugs to hold the whole structure securely together.
The operation of my improved as follows:
engine is vWith the parts in the position shown in Fig. 1 the'rotor will he turned in a clockwise directionfby ny approved means and as the piston-slide 6 passes from under the inlet valve 9 .the valve will be forced inward by its spring and communication betweentheinlet port 7 and' the space (a will be opened through the passage 24. '.l he pisston-c', havingteen forced outward by the spring 18, will now begin to suck gas through the port. As the piston e approaches the end of the space a it will be forced. inward-by the wall of the space, and the piston Z will come under the valve 9 and raise it cutting oil the supply of gas. The gas-draw yinjby the piston e will be cong I v I The valve 10 which will descend and the charge of compressed gas will rush out of the cavity 29 behind the pistonc and be exploded by the sparking device 34.. This explosion will drive the piston in the cloeinvisr dir ction until it passes the exhaust 8. The piston slide 6 will in the meantime have passed the transfer valve 10 and be driven around by the new explosion and will scavenge the space 6 of the products of Combustion of the first explosion. This operation will be repeated on each side of the engine or as many times as there are transfer valves and spark plugs and as many times as there are piston slides.
\Vhen the inlet and transfer valves are raised by the piston slides the perforations in the extensions25 will be masked by the pistons 27 and the air imprisoned below the pistons will act as a cushion and its expansive force will aid the spring 26 in seating the valve.
he springs 18 need be of a strength only suflicient to move the slide pistons radially outward during the cranking operation. When the engine begins to turn over owing to the explosions of the gas,,the centrifugal force will be sufficient to operate the piston slides without the aid of the springs.
The blocks 19 may be provided with serrations 35, as shown in order to minimize leakage past them and to form oil spaces between them to lubricate the interior of the engine.
When the form of the apparatus shown in Fig. 6 is used, outer walls of the spaces a, b, c and aare made on parabolic curves with the surface a leading up gradually from a point near the gas checks 22. This surface and no springs or cushions will be required.
In accordance with the provisions of the patent statute I have described the rindplcs of my invention togetherwith t e apparatus which I now consider to represent the best embodiment thereof, but I'desire to have it understood that the apparatus is merely illustrative and that the invention may be carried out in other ways.
Having now described my invention, what I claim and desire to secure by Letters Patent of the United States is:
1. An internal combustion engine comprising a stator, a fuel inlet in the stator, an inlet valve, a tapering fuel chamber in the stator, a rotor mounted in the stator, a piston slide movable radially'in the rotor, tapered adjustable plates carrying the pie ton slide, cheek lates between the rotor and the stator an gas checks carried by the stator.
2. An internal combustion engine, comprising a stator and'a rotor, a tapering compression chamber in the stator, a transfer valve, a piston slide movable radiall in the rotor and engaging the walls of t e compression cham er, whereby gas will be com presed in the chamber, there being a passage at the small end of the compression chamber, means whereby the piston slide may engage the transfer valve and move it into position to receive the compressed charge from the compression chamber, a combustion. chamber, positively acting means for movin the transfer valve into position behind t e piston slide when the
