71/4 35 5555 J/Z/EU/UR 7 2Z/ Maxg THOMAS J. FAY, 0F BROOKLYN, NEW YORK, ASSIGNOR TO THE GOBY ENGINE.
COMPANY, A CORPORATION OF OHIO.
T 0 all whom it may concern v Be it known that I, THOMAS J. FAY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certainnew 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 mechanism therefor, the valve mechanism being of the general type shown in the application of Clifford S. Goby for Letters Patent of the United States No. 514,098, filed Aug. 23, 1909. In the aforesaid application, a valve of the sliding sleeve type is shown, the sliding sleeve valve being interposed between an outer cylindrical valve casing and an inner lining sleeve or bushing having an abutment therein.
It is the object of the present invention to provide valve mechanism of the aforesaid type wherein means are provided for efli ciently cooling the internal sleeve or liner and wherein the leakage of combustible fluids and gases of combustion is largely prevented.
A further object of the invention is to provide valve mechanism of this type which is comparatively simple of construction and economical and efficient in operation, Which is easily assembled and disassembled, and which is capable of efficient lubrication.
Further and more limited objects of the invention will appear hereinafter, and the invention may be described further and more-generally as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein:
Figure 1 represents a vertical sectional view through an engine cylinder, the valve mechanism, and part of the crank case, and showing the driving connection between the engine shaft and the valve or lay shaft;
and Fig. 2 a sectional view corresponding to the line 22 of Fig. 1.
Describing by reference characters the various parts illustrated herein, 1 denotes the crank case and 2 the cylinder of an internal combustion engine, an engine of the fourcycle type being illustrated herein. While but a single cylinder is shown and described Specification of Letters Patent.
Application filed August 2, 1913.

Serial No. 782,582.
for clearness of illustration and facility of description, it will be appreciated by those skilled in the art that a multi-cylinder engine may be employed and that my invention as herein disclosed is equally applicable to such an engine, such application being within the skill of the mechanic.
3 denotes a piston mounted in the cylinder, 4 the connecting rod, 5 the engine crank shaft and 6 the Wristpin for the connecting rod. Projecting from the crank case 1 is a lay-shaft chamber 7, and located Within said chamber is the lay shaft 8, the lay shaft being driven from the engine crank shaft 5 by any suitable reduction gearing-sprockets 9 and 10 and a chain 11 being shown for this purpose. In the embodiment of the invention illustrated herein, a 2 1 reduction drive from the engine shaft is provided.
Surrounding the cylinder 2 is a water jacket shell 12, preferably cast with the cyl- Also cast with the cylinder and with the water jacket casing is a cylindrical valve shell or casing 13 having its axis arranged at an angle to the axis of the cylinder 2 and communicating intermediate of its ends with the cylinder by means of a duct 14. Two such shells or casings 13 will be used, one for the inlet fluid and the other for the exhaust fluid, and the duct 14 will preferably be made of such width and shape as to communicate with both valve casings, in sub-.
stantially the same manner as shown in my applications hereinbefore referred to.
Reciprocably mounted in each valve shell or casing 13 is a sliding sleeve valve 15 which is connected to the lay shaft 8 by means of a crank arm 16 and-a link 17, the parts being proportioned so that the top of the valve sleeve 15 will be brought below the bottom of' the duct 11 while the crank arm 16 is passing its lower center, at which time the duct 14 will be in communication with the interior of the valve and particularly with the interior of the liner sleeve.
The liner sleeve is made conveniently in two sections, 18 and'19. The part 19 is shown as threaded into the upper end of the valve casing 13 and is provided with a flange 20 adapted to abut against the top of the casing. The lower end of the section 19 is closed by an abutment 21 which is located immediately above the duct 11.
The sleeve section 19 is of sufficiently smaller diameter than the valve casing 13 to provide an annular space 22 therebetween, said space being of sufficient Width to receive therewithin, with proper clearance, the upper end of the valvesleeve 15. The lower sleeve section 18 is mounted Within the valve sleeve and is shown as angularly deflected at its lower endsee 18 being provided at the end of its deflected portion with a flange 23 which is adapted to abut against the wall of the casing 7. A similar flange 24 is carried by the cotiperating duct 25 for the exhaust or inlet fluid (as the case may be), the said duct and the lower end of the sleeve section being. secured in place by means of screw bolts 26 extending through the flanges 23 and 24: and threaded into the casing The upper end of the inner or liner sleeve 18 terminates a sutficient distance from the abutment 21 to provide therewith an annular port 27 within the interior of the inner sleeve, which port registers with the duct 14L when the valve sleeve 15 is in its lowermost positionwhen the crank 16 is passing its lower center. The wall of the valve casing 13 which is opposite the cylinder is outwardly deflected to provide a fluid space 28 which is in communication with the duct 14 and which enables the pressure within the cylinder and the duct 14: to be equalized around the valve sleeve 15, to prevent binding.
The water jacket casting 12 is extended around the valve casin 13, whereby the cooling liquid may be circulated around said casing, and the upper end of the sleeve section 19 is in free communication with this space, whereby the upper liner section 19 and the abutment 21 are subjected to the cooling action of this liquid. The casing has an opening above and registering with the upper end of-the upper liner section 19, said opening being provided with a remov able cover 29 whereby access may be had to the section 19, permitting its convenient insertion and removal.
A spark plug 30 of any approved construction is shown in the head of the cylinder, and an oil supply pipe 30 projects through the casing 7 above the lower portion of the valve sleeve 15 and is adapted to supply lubricant to the lower portion of said sleeve and to the outer surface of the liner section 18.
With the parts arranged and constructed as described, it is believed that the operation will be clear. The combustible fluids will enter the cylinder above the top of the sleeve 15 of the inlet valve and the fluids'of combustion will escape above the top of the corresponding sleeve of the exhaust valve. The annular space 22 provides a trap wherein the atmosphere and the gases of combustion will be compressed by the sliding valve sleeve 15 and thus prevent leakage of the in let and exhaust fluids. The amount of compression may be adjusted, if desired, or may be made constant.
Having thus described my invention, what I claim is 1. In an internal combustion engine, the combination, with a cylinder, of a valve casing adjacent to the cylinder and provided with a port intermediate of its ends communicating with the cylinder, a sliding sleeve valve mounted within the casing, a liner section within one end of the valve casing and extending from such end to a point adjacent to the port and there provided with an abutment, there being an annular space provided between such section and the casing for the reception of the sleeve of the valve, a separate second liner section inserted within the opposite end of the valve casing and having its end spaced from the abutment to provide a port adapted to register with the first mentioned port, and a fluid connection communicating with the second liner section.
