Application filed August 2, 1913.
' and useful Improvement in Internal-Combustion Engines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention relates to internal combustion engines and more particularly to the valve mechanisms therefor, the valve mechanism disclosed herein being of the slidingsleeve type,'such-as disclosed in the applications of Clifford S. Goby No. 514,098, filed August 23, 1909; No. 568.612, filed June 24, 1910; No. 709,927, filed July 1.7, 1912. In the construction shown and described in the aforesaid applications, a sliding sleeve valve jreciprocates within a cylindrical casing which communicates with the cylinder, there being an abutment within the valve (carried by a. liner sleeve), located adjacent to the said portand serving, in the inlet valve, to deflect the combustible fluid into the cylinder and serving, in the outlet valve, to deflect the exhaust gases entering the valve from the cylinder.
It is the purpose of this invention, in a construction of the foregoing type, to provide means whereby the valve sleeve may be efliciently guided and the fluids isolated .from the crank case, or the case for the layshaft, while securing eflicient cooling of the abutment and of the liner by which it is carried.
With the foregoing general objects in view, the invention may be further defined .as consisting of the combinations of elements set forth in the claims hereto annexed and illustrated in. the drawings forming part hereof, wherein Figure 1 shows a longitudinal sectional view taken through the cylinder, a part of the crank case and one of the valves, the valve mechanism being constructed in accordance with my invention; Fig. 2 represents a sectional view corresponding to the line 22 of Fig. 1.
Describing by reference numerals the various parts illustrated herein, 1 denotes the crank case, 2 the cylinder, and 3 the piston of an internal combustion engine.

Serial No. 782,583.
4; denotes the engine crank shaft, 5 one of the wrist pins, and 6 the connecting rod.
For facility of description, a single cylinder engine is shown, but it will be obvious to those skilled in the art that a multi-cylinder,engine may be employed. The cylinder is shown as provided with a water jacket casing 7, which is preferably extended, as shown at 8, to surround the valve casings.
Projecting from the upper end or head portion of the cylinder is .a duct 9, said duct being of the shape shown in Fig. 2 to include the casings 10 of the inlet and exhaust valves, which are of identical construction. The duct 9 is extended around the valve cas- 1ngs, as shown at 11, whereby the sliding sleeve valves therewithin are subjected throughout their circumferential extent to the pressure of the gases within the cylinder, thus avoiding binding. In the embodiment of my invention disclosed herein, the axis of the valve casing is substantially parallel with that of the cylinder.
As is the case with the prior forms of my invention, a liner or bushing is provided for the interior of the valve casing, said liner or bushing being provided with an abutment adjacent to the ductv which communicates with the cylinder. In the particular form of my invention disclosed herein, this liner is made in two sections, one section being detachably fitted to the top of and depending within the valve casing and the other section being longitudinally spaced and suspended from the first section. The first section is ahollow tubular member 12 which is threaded into the top of the valve casing 10 and is provided with a nut flange 13 adapted to abut against the top of the casing. The section 12 is provided at its lower end with an abutment 14, located preferably immediately above the duct 9 and the port 9 in the valve casing which communicates with said duct. This hollow section 12 is in free communication with the water jacket, and the casing S is provided with a removable cover 15 above the liner section 12. enabling the latter to be conveniently inserted and removed, as occasion may require.
The second liner section comprises a hollow abutment 16 which is suspended from the section. 12 by a tube 17. The abutment 16 is located immediately below the fluid connection 18 and serves to deflect the inlet fluids toward the abutment 1i and the port 9 and to deflect into the outlet connection the exhaustgases which are supplied through the like-designated port of the exhaust valve. The tube 17 admits cooling liquid from the upper liner section to the lower liner section.
A sliding sleeve valve 19 is reciprocably mounted within the casing 10 and is provided with a port 20 in its wall which is adapted to register with the connection 18. This sleeve is reciprocated by means of the lay-shaft 21, crank 22, and link 23. The lay-shaft is driven from the engine crankshaft by suitable reduction gearing, a chain 2st and sprockets 25 and 26 being shown for this purpose. The port 9 is preferably controlled by the upper end of the valve sleeve 19, the valves in this case being driven at a two-to-one reduction from the engine crank shaft. An inlet or exhaust pipe, 27, is shown. as communicating with the duct 18.
Having thus described my invention, what I claim is:
1. In an internal combustion engine, the combination, with a cylinder, of a valve casing having a port communicating with the cylinder and a port longitudinally spaced from the first mentioned port, a valve sleeve reciprocably mounted in the casing and adapted to cover and uncover the first men tioned port and provided with a port adapted to communicate with the second port, an abutment within one end of the valve casing adjacent to the first mentioned port, and a second abutment carried by the first mentioned abutment and located within the valve sleeve adjacent to and shaped to guide the flow through the second port, said casing ports being included in the space between said abutments.
2. In an internal combustion engine, the combination, with a cylinder, of a valve casing having a port intermediate of its ends communicating with said cylinder and having a port beneath and longitudinally spaced from the first mentioned port, a liner sleeve within the upper end of the valve casing and extending adjacent to the first port and there provided with an abutment, a hollow abutment depending from the said liner sleeve and located below the second port, a tubular connection between the said liner sleeve and said second abutment, the second abutment being provided with an upwardly curved wall extending away from the second port, and a sliding sleeve valve mounted between the said casing and the said liner sleeve and abutments and having a port adapted to register with the second port.
8. In an internal combustion engine, the combination, with a cylinder, of a valve casing having a port intermediate of its ends adapted to register with the second port.
