an-oomnns'rron ENGINE.

Application filed. August 3, 1920, Serial-Ito. 400,993. Renewed August 9, 1922. Serial No. 580,811.

To all whom it my concern:

Be it known that I, COY GEORGE, a citizen of the United States, residing at Blytheville, in the county of Mississippi and State of Arkansas, have invented new and useful Improvements in TnternalCombustion Engines, of which the following is a specification.

This invention relates to internal combustion enginesand comprehends the construction making use of a stationary piston arranged Within a sleeve connected with the crank shaft for reciprocatory movement within the cylinder, the sleeve being designed to provide compression and firing chambers at its opposite ends, whereby every stroke is a power stroke, thus providing for compactness, lessfloorspace and a motor which will develop as much power as a two cylinder two cycle engine.

Another object of importance resides in the provision of a construction, wherein the piston is cooled by water circulation, the water passing through the piston pin which is in open communication with the water jacket, means being also devised to allow for the escape of air from the piston.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a side elevation of the engine partly in section.

Figure 2 is a vertical sectional view taken at right angles to Figure 1.

Figure 3 is a view in elevation of the piston removed.

Figure 4 is a similar view of the recipro catory sleeve.

Figure 5 is a view of the crank shaft. Figure 6 is an enlarged fragmentary sectional view of a modified form of the invention.

Referring to the drawings in detail, 10

indicates the crank shaft of the motor, in

Figure 1, andv the water may be drained from the jacket by means of a pet cock indicated at 14 in Figure 1. The water pump 15 is arranged at one side of the cylinder and actuated from the crank shaft 16 journaled in suitable bearings 17 of the crank case, and equipped at one end with the fly wheel 18. The carbureter occupies the space indicated-at 19 in Figure 1. Aplurality of spark plugs 20 are mounted in one side of the cylinder, there being two of these plugs for the respective firing chambers to be hereinafter described. The crank shaft 16 is provided with counterbalancing weights 21.

Arranged within the cylinder 11 at a point approximately midway between the ends thereof, is a stationary piston 22 sup ported by a pin 23 which projects beyond the sides of the piston and received by suitable bearings in the cylinder. The piston is equipped with packing rings 24 and is further provided at each end with an extension 25 constitutin a deflector for the gas or combustible 'mlxture admitted to the firing chambers. The piston 22 is arranged within a sleeve 27 of suitable length to define

firing chambers

28 and 29 respectively in the opposite sides of the piston 22. This sleeve is closed at both ends, the upper end being closed by means of a removable head 30 while the lower end 31 is positioned an appreciable distance within the sleeve 27. The sleeve 27 is associated with the crank shaft by means of a connecting rod 32 which has one end arranged within the sleeve immediately beneath the lower end Wall 31 and connected thereto by means of the pin 33. Vertically disposed slots 34 are provided in the sleeve to receive the pin 23 which supports the stationary piston 22. The sleeve 27 is further provided above and below the slot 34 with inlet ports 35 and exhaust ports 36. These ports are of course adapted to be brought into registration at the proper time with the terminals of the intake manifold 37 and the exhaust -manifold 38. The space within the cylinder 11 above the sleeve 27 defines a compression chamber 39, while the space within the crank case beneath the lower end of the sleeve-constitutes a com-' pression chamber 40. The-cylinder is formed with a passage 41 to establish communication between the compression chamber 39 and the firing chamber 28 when the sleeve 27 is in its uppermost position, the cylinder being further'provided with a passage 42 to establish communication between the compression chamber 40 and the firing chamber 29 when the sleeve is in its lowermost position. Obviously, the inlet ports 35 of the sleeve are alternately brought into registration with the

respective passages

41 and 42. Similarly, the exhaust ports 36 of the sleeve alternately register with the respective terminals of the exhaust manifold 38. The sleeve 27 is also provided with spaced openings 43 through which the spark plugs fire at the proper intervals.

In practice, assuming that the sleeve is in the position shown in Figure 2, the burnt gases exhaust from the firing chamber 28 through the manifold 38, and the combustible mixture from the compression chamber 39 enters the firing chamber 28. The combustible mixture which is conveyed from the chamber 39 into the passage 41, is directed against the extension 25 which de fleets the mixture upwardly in the chamber 28. \Vhen the charge now contained in the fining chamber 29 is fired, it drives the sleeve 27 downwardly thus cutting off com munication between the chamber 28 and the passage 41, and bringin the inlet and exthe combustible mixture is transferred from the compression chamber 40 into the firing chamber 29 through the passage 42, this mixture being directed against the projection 25 which deflects the combustible mixture in the proper direction and prevents it from mingling with the burnt gases which are being exhausted through the exhaust manifold 38. It is of course understood. that during the down stroke of the sleeve 27, the combustible mixture is drawn into the compression chamber 39. At predetermined intervals during the down stroke of the sleeve, the spark plug in the firing chamber 28, stnikes the reviously mentioned charge contained in the said chamber, thus driving the sleeve in an upward direction to the position which it assumes as shown in Figure 2. Manifestly, every stroke of the sleeve is a power stroke, or in other words. there are two power strokes at each revolution of the crank shaft. The engine will not only develop as much power as a two cyl inder two cycle engine, but the arrange- 4 ment provides for compactness, the parts heing readily accessible, while economy in floor space is another important feature pro vided for by the invention.

In Figure 6 I have illustrated a modified form of the invention wherein 50 indicates the cylinder which is provided with the usual water jacket 51. 52 indicates the piston which is the same in construction as the piston 22 above described, the piston Utflllg arranged within the sleeve 54 a suitable length to define the fining

chambers

55 and 56 respectively. The sleeve is of the same construction as the sleeve 27 above referred to. Passed through the vertically disposed slots 56 in the sleeve is a hollow pin 57 which is threaded into the water jacket as shown, the pin being provided with openings 58 adjacent the ends thereof and by means of which communication is established between the water jacket and the pin at 57. A portion of the pin is arranged within the sleeve is also provided with a plurality of openings 59 so that water may circulate within the piston. the water circulation being through the water jacket and pin 57 as will be readily understood. An angularly shaped pipe including a vertical flange 59' is extended through one of the openings 58 of the pin vertically within the sleeve, a horizontally disposed branch 60 of the pipe being passed through the'pin beyond one end thereof and-is equipped with a pet-cock or the like 61. The pipe is designed to oc-.

cupy a minimum space, and is utilized to permit of the escape of air from the sleeve so as not to retard the circulation of water Iin any way. Otherwise, this form of the invention is the same as that above described.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that 1 do not limit myself in the details herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
