. Applicationi'November 30,1932, Serial No. 645,055 Y 2 Claims (019123-190) This invention relates to an improved revoluble valve for multiple cylinder internal-combustion engines thepurpose being to provide a valve of this character capable of operative association-in connection with two cylinders, making it possible to use a single valve to cooperate with the intakes and exhaust ports of two-cylinders.

Another purpose is to provide, in'an engine of this kind a valve including apartition therein so arranged as to separate two ports formed inthe valvein order to so alternately register with the ports of the combustion chambers of the cylinders as to. first permit of intake of a'charge and then permit of exhaust of the utilized gases, the crank shaft of the engine being so geared with a shaft (which is so operatively connected with the revoluble valve) as todrive theshaft at a ratio of 2' to -1, namely if two revolutions of the crank shaft will cause one revolution of said shaft which in turn operates the valve.

Another purpose is to provide a valve of this kind inassociation with an internal combustion engine, preferably of the two cylinder type, having annular grooves in the exteriorsurface of the valve above and below the ports, with inclined grooves above and below the'first grooves, which permit lubricant to feed to the surface of-the valve, and against the interior'wall of the valve cylinder, together with sealing means to seal the oil and prevent end play.

It is to beunderstood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention,

' any desired modifications of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings: I

Figure 1 is a vertical sectional view through the improved engine showing the valve applied.

Figure 2 is a sectional view on line 2-2 of Figure 1 showing the cylinders and their ports or passages connecting with the valve cylinder.

Figure 3 is a horizontal sectional view on line 3--3 of Figure 1.

Figure 4 is an enlarged detail view of the revoluble valve, with its wall broken away to show the partition between the two ports.

Figure 5 is a sectional view through the oiler.

Figure 6 is a view in front elevation of the cage which houses the revoluble valve, showing the guard 53 in dot and dash lines in order to expose the parts behind it.

Referring to the drawings l identifies'the casing of the engine, which comprises the two cylinders 2 and the crank case 3, the cylinders being bolted to the crank case at 4: Bolted at 5 to the crank case, is the usual oil pan 6, and mounted in bearings of the crank lcase'is a crank shaft 1, to which the usual connecting rods 8 are connected 'by means of the bolts 9 andcap plates I0. Connecting rods 8 are in turn pivoted to the pins l' l which extend transversely of the pistons I2 which are provided with the usualpiston'lings'lfiij The cylinders 2 are provided with the usual water jackets/l4, while the head l5 (which is bolted at IE to thecylinders) is likewise provided with a water jacket ll, which communicates with the jacket v I4 in'any well known conventional man- Es )PA ur ner. The interiors [8 of the cylinders merge into compression chambers 19, in each of which the charge is compressed, on the compressionstrolge of the piston. I

Carried by and forming part of the casing of the engine is a valve casing 20, which hasa water "jacket 2!, which in turn communicates with the water jacket I4 of the cylinders. Mounted in the valve casing is a single revoluble valve 22, which. has in its Wall ports 23 and 24. The valve 22 is in the form of a hollow cylinder and is connected at 25 to a valve stem '26, -whichoperates through a guide 21 of the wall of an intake manifold 21a, which is bolted at 28 to the valve casing. An exhaust manifold 29 is boltedat 30 to the valve casing 20. Adjacent the remote opposite ends of the valve 22 are oil rings 3l' and 32, the former being in contact with the end of the exhaust manifold 29, while the latter is in contact with the end of the intake manifold 2100. These oil rings act to prevent lubri- I cant from reaching the interiors of the intake and exhaust manifolds.

The lower end of the cylindrical valve 22 is provided with intake ports 33, which communicate with the intake manifold. The exterior surface of the valve is provided with annular oil grooves 34 and diagonally inclined oil grooves 35, there being a suitable oiler 36 connected to the valve casing 20 by means of the threaded a :worm 41 mounted on the crank shaft.

result of the crankshaft revolving imparting motion from the worm- 41 to the worm gear 46, hence imparting 'revoluble movement .to the with the ports 40 and ll which communicate the compression chambers I9 with the interior of theflvalve casing, thereby allowing alternate intake charges to enter the compressionchambers on the suction strokes of the pistons in the cylinders, as well as'permitting alternate exhaust of the utilized gases upon exhaust strokesof the pistons.

The valve stem 26 is connected at 42 to'a shaft 43 which passes through a'guidei'44, which is, anchored within and to the crank case 3, the

guide being adjustable for wear by means of the set screw 45. Mounted on the lowerend of the shaft 43 is a worm gear 46, which meshes with- As av Shaft 43 as well asthe valve stem 26,'thereby rotating the valve, sothat its ports may register with the compression chamber. The shaft 43 passes through a packing gland 48, and as previously stated is coupled at 42 to the valve stem.

Thevalve stem'26 passes through a second packing gland. Suitable collars 50 and 5| surround the shaft 43 and the valve stem 26 and act to retain the packing in place, particularly so since a relatively strong expansion spring 52 is .interposedbetween the two collars 50 and 51 and in surroundin'g relation with a. portion of the .s haft 43 and the valve stem 26 and-acting to spread the collars apart. In order to preclude dust' and dirt or other foreign matter about where'the shaft 43 and the stem 26 are coupled 'andirom between the convolutionsof the spring, asuitable shield or guard 53 is positioned beween a part ofthe crankcase and the intake manifold.

Located withinthe oil pan and bolted at 54 .to ther lower part of the crank caseis an oil pump 55'having an oil line 56 passingthrough a packing plug 51 and in turn connected to the oiler1or lubricator 36 for the valve.

From the foregoing it is obvious that an improved :revoluble valve is provided for use in controlling alternate intake charges to the two cylinders as well as controlling alternate exhaust of the utilized gases, it also being obvious how 'the engine and the valve operate.

The invention having been set forth,;what is claimed is:

1. The combination with an internal combusvalve having upper and lower exhaust and intake chambers and provided with intake and exhaust ports alternately communicating the intake and exhaust chambers got the valve with said combustion chambers, exhaust andintakepassages above and below the valve and communicating with the upper, and lower exhaust and. intake chambers of the valve, said stationary thrust bearing oil rings being serviceable to prevent seepage of oilintothe exhaust and-=intakepassages and the. chambers, and means to rotate the valve. 7 i

2. The combination with} an internal combusj tion engine including a casing having a crank case .and a multiple of cylinders including pi s tons operable therein,. of -a cylindrical valve chamber formedin said engine casing andhaving multiple combustion chambers connecting the cylinders'and the valve chamber, exhaust and intake. manifolds above and below and communicating with the valve chamber, upper and lower stationary thrust bearing v oil rings in said valve chamber, a cylindrical hollow revoluble valve in the valve chamber and serviceable between the stationary thrust bearing oil rings, said valve having upper and lower exhaust and intake chambers communicating with the ,ex-

haust and intake manifolds, said valve having intake and exhaust ports communicating the intake and exhaust chambers of the valve alternatively with the multiple combustion chambers, and means to rotate the valve. I j
