INTEQNAL-COMBUSTION ENGINE.

Application filed August 2, 1313.

To ((ZZ 207mm it may, concern Be it known that I, TnoMAs J. FAY, a citi- Zen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new 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 especially to valve mechanism therefor, the valve mechanism shown herein being of the sliding sleeve type, such as exemplified 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'17, 1912.

It is the general object of this invention to provide valve mechanism of this type wherein the inner liner section may be efficiently cooled and wherein convenience of assembling and disassembling may be secured.

Further objects of the invention will appear hereinafter and will be set forth in the specification and claims hereto annexed.

In the drawings forming part hereof, Figure 1 represents a longitudinal sectional view taken through a cylinder and. one of case being shown; Fig. 2 represents a transverse sectional view corresponding to the line 2-2 by reference characters the various parts illustrated herein, 1 denotes the crank case, 2 the cylinder, 3 the piston, 4 the connecting rod, 5 an engine crank shaft, and 6 the wrist pin of an internal combustion engine. For facility and clearness of description a single cylinder engine is here shown and described, but it will be apparent to those skilled in the art that my invention is equally applicable to a multicylinder engine.

7 denotes the fluid duet'extending from the cylinder head, said duct being of the Describing shape shown'in Fig. 2 and-placing the cylin der in communication with the ports 8 formed in the cylindrical valve casings 9, two such valve casings being shown, one for the admission. fluids and the other for The valve casings 9 are preferably cast with, but spaced from, the

cylinder, and the duct 7 extends around the parts of the valve casings which are remote Specification of Letters Patent.

.iroin the cylinder,

Within the cylinder may be transmitted around and thus balancethe pressure upon whereby the pressure the sliding sleeve valve which reciprocate-s within each valve casing and thus prevent binding thereof.

Mounted Within spaced therefrom to .provide an annular valve seat is a hollow abutment 10, this abutment being of cylindricalshape and being located adjacent to and immediately above the port v8. dhis abutment is conveniently supported by means of a second hollow abutment 11, which is threaded into the lower end of each valve casing, being provided with a flange nut 12 for conveniencc' of application to and removal from the valve casing. The abutment 10 is supported frein the abutment 11 by means of a pipe 13, which is attached to the abutments in any convenient manner, and is in communication with the hollow interiors thereof. The upper surface 14 of the abutment 11 curved upwardly away from a port 15 which is formed in the wall of the valve casing 9 which is remote from the cylinder 2, and a fluid conducting pipe 16 is in communication with this port. In the case of the inlet valve, the combustible fluids enter the interior of the valve casing 9 throughthe pipe 16 and port'15, between the abutments 10 and 11; in the case of the exhaust valve, the gases of combustion enter the interior of the valve casing between the said abutments and are delivered through the port 15 into the pipe 16.

17 denotes a lay-shaft, which is driven preferably at a two-to-one reduction from the crank shaft 4-. This lay shaft is providedwith cranks 18 and wrist pins 19 to which links 20 are connected, one foreach sliding sleeve valve. The upper or outer end of each link is connected to arod 21 which extends upwardly, outside of the valve casing 9, and is connected at its upper end to a projection or spider 22 at the upper end vof the sliding sleeve vvalve 2-3. This sliding sleeve valve reciprocates within the valve casing 9 and in the annular seat provided between the abutment 10 and the valve casing. Itis preferably so arranged that the lower endof the valve uncovers the port -8 While the crank 18 is passing its upper center. v

The cylinder 2 is shown as provided with each valvecasing and a water jacket provided by the shell 2t, said shell extending around the cylinder and around the valve casings, as shown at25. For the purpose of cooling the abutment-s l and 11, the pipe 26 may be provided, said pipe communicating with the water acket, extending upwardly and then downwar ly within the valve sleeve 23 and communicating at its lower end with the abutment 10. To allow for circulation of the cooling liquid through the abutments, the abutment 11 may communicate near its lower end with the water jacket space through ports 27 and 28 provided in said abutment and in the wall of the valve casing 9. Circulation may thus take-place through these ports, the pipe 13, the abutment 10, and the pipe 26.

If desirable, a dust cap 29 may be applied to the water jacket casing to cover the upper end of the valve casing and the liquid con nection 26, to protect the parts from the access of any undesirable material.

Having thus described my invention, what I claim is 1.
