INTERNAL-COMBUSTION ENGINE.

Application tiled March 20, 1914, Serial No. 826,054. Renewed October 23,

To all whom it may concern:

Be it known that I, THOMAS LANE, a citizen of the United States, residing at At- State of Georgia, have invented certain new and useful Improvements in Internal-Combustion I do hereby declare the foland exact descripbeing had tothe accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to internal combustion engines of the type set forth in my Patent No. 1,087 ,499, dated February 17, 1914, the objects of the inventionbemg to improve the construction and arrangement of the valve mechanism, whereby the ports and passages may be more advantageously disposed and the valve more effectually packed to prevent leakage or loss of pressure during the compression and power strokes. i

The invention consists in the novel details of construction and combinations and arrangements of parts which will be hereinafter described and pointed out particularly in the appended claims.

Referring to the accompanying draw-' ings,Figure 1 is an elevation, one-half in section, showing a cylinder, valve mechanism, piston and crank shaft embodying the present improvements.

lowing to be a full, clear,

Fig. 2 1s an elevation from a point of view at right angles to Fig. 1, with the upper portion of the cylinder and valve chamber in section. Fig. 3 is a plan view of the valve and the cylinder head with the upper portion of the valve chamber removed. Figs. 4 and 5 are views ofthe spherical valve shown in Figs. 1 to 8 and 9 are sections in, vertical planes, through a slightly different preferred: arrangement of valve, Fig. .G/be ing a section on the lines 66, Figs. 7 and 8; Fig. 7 a section on the line 7-7, Fig. 6; Fig. 8, a section on the line 8-8, Fig. 6; and Fig. 9 a section on the lines 9-9, Figs. 7 and 8.

Like letters of reference in the several figures indicate the same parts.

. Certain parts of the engine illustrated are of conventional form, that is to say, there is preferably employed the usual water jacketed cylinder A, piston B, connecting rod 0 and crank shaftD. Above the cylinder there is formed a spherical valve chamber,

such chamber being preferably formed onehalf in the head of other half in a removable head E, which is the cylinder and the secured in place by bolts and nuts F of ordinary construction, ing such that the water jacket around the cylinder communicates with corresponding water .jacket passages in the head E, in the well known way.

Fitting within her is a spherical valve .11 mounted on a shaft I journaled in bearings formed between the cylinderhead and removable head, so that the valve with its shaft may be lifted out or inspected when the moved. The valve is keyed to its shaft and the spherical valve chamhead- E is rethe arrangement beis adapted to be rotated at one-half the speed of'the crank, fora four-cycle engine, by a sprocket chain running over a sprocket wheel K on the. crank shaft and over asprocket wheel K adjustably connected with a valve shaft disk by screws 70, whereby the timing of the valve may be accurately adjusted. I

In the construction shown in Figs. 1 to 5, theinlet port L and the exhaust port M are located approximately at opposite points loweredge of the inlet port being, however,

slightly above the level of the lower edgeof the exhaust port,

and the two ports are formed. partly in the cylinder head and on each side of the valve shaft, the j partly in the removable head E. They are preferably formed in parallel pairs, as will be readily understood from Fig. 3, for convenience'in manufacture and to strengthen the parts of the cylinder and valve, as will be presently understood; Inthe head of the cylinder and at the bottom of the valve chamber cylinder ports N are formed, and

the valve, which in this instance may be a hollow sphere, ,is formed with transverse slots which constitute the inlet and exhaust passages h, extending straight through one hemisphere of the yalve, as indicated by the dotted line 72/ in Fig. 2, and as shown in the perspective view, Fig. 5. The two slots through the spherical valve communicate in the interior of the valve and thiis, in effect,

the pairs of ports and passages constitute.

a single duct. The cylinder poit N and the inlet' and exhaust ports are approxiit will be under stood, is subject to variation within limits,

engine.

according 'to' the particular design of the.

'The opposite hemisphere of the valve I are mounted in'grooves P, which it will be seen from Fig. 4, intersect at an acute-angle, the points of intersection being on opposite sides-of the valve, preferably in proximity to the axis or valve shaft. This arrangement leaves a very large area in which the passages may be formed and also a very I25. ures. of the drawings, the inlet port is indilarge area which is completely surrounded by the packing rings and may be utilized for presentation to the cylinder ports during the compression and power strokes.

In Figs. 6 to 9, inclusive, the arrangement is'one in which separate and independent inlet and. exhaust ports and passages are employed, both in the cylinder and in the valve, but the arrangement of packing rings may remain the-same as that heretofore de scribed. Referring particularly to said figcated' at R, the cylinder inlet port at R, the exhaust port at S and the cylinder exhaust port at S. The inlet passage in the valve is indicated at R and the exhaust passage at R the valve in this case being'provided with a diaphragm or. partition through the same to separate the two passages. R and S and divide the internal chamber into inlet and exhaust chambers. In this instance the exhaust and inlet ports R and S are formed entirely in the removable head E, their lower edges therefore being substantially level with the axis of the valve, and the passages in the valve preferably extend through approximately 180 of the circumference of the valve. As shown in Fig. 6, the inspiration stroke is about to commence, and as shown in Fig. 9, the power or explosion stroke is about to commence. From this last mentioned figure of the drawing it will readily be appreciated that upon the closure of the cylinder port and before the piston memes inspection of Fig. 7, thus permitting of all 7 cf theadvantages of separate inlet and exhaust ports and passages, without in any wise c plicating the problem of packing and kee ing the valve tight against loss of compression or ower.

Packing rings'of ordinary construction having spherical outer surfaces I are employed, the ends of each ring being out diagonally to, fit against the sides of the complemental ring at the point of intersection.

Thespherical valve which is hollow forms a chamber having the greatest cubical capacity possible in a valve of given size. lhe chamber acts as an expansion chamber into which the gaseous fuel will expand, and in accordance with the well known law governing the absorption of heat by expanding gases, the action will assist materially in keeping the valve. walls cool.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. In an internal combustion engine, the combination with a cylinder head, of a rotary spherical valve, there being compleq mental ports and passages in the cylinder head and valve controlling admission and exhaust of motive fluid, and. a plurality of yielding packing rings, all extending around the valve in the same hemisphere.

2. In an internal combustion engine, the combination with a cylinder head, of a rotary spherical valve, there being complemental ports and passages in the cylinder head and valve controlling admission and exhaust of motive fluid, and .a plurality of yielding packing rings located in different planes in thevalve and in the same hemisphere.

3. In an internal combustion engine, the combination with a cylinder head, of a rotary spherical valve, there being complehas reached a point where the compression qnental ports and passages in the cylinder begins to materially increase the packing rings will have moved. across the cylinder ports and the escape of pressure around the valve will be effectually prevented, during the completion of the compression stroke and during the power or explosion stroke, the last of the rings moving into the area of the cylinder ports only as the piston reaches the limit of its downward movement in the power stroke.

Obviously with the arrangement of the packing rings in the opposite hemisphere of the valve from that in which the passages are formed, a very considerablelatitude for thelocation of said passages is permissible,
