INTERNAL-COMBUSTION ENGINE.
Specification of Letters Patent.
Patented Nov. 3, 1914 Application filed September 3, 1313. Serial No. 788,038.
To all whom it may concern Be It known that I, JAMns K. Doses, a
citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following .is a specification, reference being had to the accompanying drawings.
This inventlon comprehends certain new and useful improvements in internal combustion engines and has for its primary object to provide an internal combustion engine of improved operation.
Another object is to provide an internal combustion engine which will be provided with curved slide valve members forming a divided sleeve around the cylinder and water jacket.
A further object resides in the provision of an internal combustion engine with transversely curved slide valve members of this character and means for supplying a lubricant to the upper ends of said members during operation of the same.
A further object is to generally improve the construction of the cylinder and water jacket and the casing within which said cylinder and water jacket are secured.
A still further object resides in the construction of an internal combustion engine of this character in which the cylinder and water jacket are cast separately fromthe casing and secured in said casing in a novel and improved manner whereby they may be readily removed and replaced shorld the same be necessary.
A still further object is to provide an internal combustion engine of this character with novel and improved mechanism for operating the piston and the slide valvemembers and provide improved lubricating and water cooling systems for the engine.
This invention has for a further object to generally improve and simplify the construction and operation of the various parts of the engine and increase the efficiency and durability thereof and at the same time reduce the cost of the same.
With the above and other objects in view,
'. Figure l is an elevational view of my stood by referring to the drawings.
complete engine. Fig. 2 is an enlarged fragmentary plan view of one of the cylinder casings, said view showing in section, a portion of said casing and one of the cylinders and valve members within the same. Fig. 3 is a vertical section on the line 3-3, of Fig. 2. Fig. 4 is a similar view on the line H, of Fig. 3. Fig. 5 is a. detail ver-- tical sectional view on the line 55, of Fig. 2; and Fig. 6 is a detail elevational view of one of the curved slide valve members removed.
Referring more specifically to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the base and 2 the cylinder casing which is preferably cast in one piece and formed to accommodate two cylinders as will be readily under- The casing 2 is preferably of rectangular form in cross-section and as the cylinder chambers 3 formed therein by the circular walls 4, said circular walls being connected at the center of the casing, as shown at 5. By providing the circular walls 4: in this manner, I have produced substantially triangular oil chambers 6 at the corners of the casing and the larger oil chambers v'2' about midway the length of the longitudinal edges of the casing, the portions of the circular walls 4 forming the curved walls of the oil chambers 6 and '1 being provided with transverse slots near their upper ends, through which oil chambers 6 and 7 oil will flow, as will be clearly understood. It will be understood that the oil chambers 6 and 7 inwardly, as shown at 18, near its upper end and then-outwardly, as shown at 21. This also increases the size of the upper portion of the water chamber. By forming the upper portion of the cylinder in this manner,
I have also reduced th size of the combus-' having nuts or the like 23 upon their extended ends. The cylinder 10 is also provided upon its upper end with the water outlet extension 24:, which extension is also engaged through the ceiling of the chamber 3, which has connected thereto a water outlet pipe 2 leading to the radiator or to any other suitable point. It will be understood that cool water from a radiator or other suitable point passes by means of the water iuletpipe 25 into the lower end of the water chamber 13, as shown in Fig. 3. 9
Slidably engaged within the chamber 3 around the outer wall 12 of the cylinder 10 are the inlet and outlet slide valve members 26 and 27, respectively, which are of substantially semi-circular form in cross-section and are provided respectively with the inlet and outlet ports 28 and 29. It will be seen that the slide valve members 26 and 27 form a complete sleeve around. the outer wall 12 of the cylinder 10, thereby locating the slide valve members outwardly of the water chamber 13. The slide valve member 27 is provided in its lower portion with the longitudinally extending slot 30 to accommodate the water inlet pipe 25, thereby permitting the slide valve member 27 to operate properly.
Each of the slide valve members 26 and 27 has a pair of depending parallel cars 31 through which is positioned a pivot pin 32 and upon the pivot pin 32 is mounted one end of a pitman rod 33, the opposite end of which is mounted upon the crank portion of a crank shaft 34: having its opposite ends mounted in the bearings 35 in the crank shaft casing 36, said crank sh aft having the gear wheel 37 mounted thereon. The gear wheels 37 are engaged and operated by a gear wheel 38 mounted on the main shaft Upon the crank portion of the shaft 39 is mounted one end of the piston rod 41, the opposite end of said piston rod being connected with the piston 42 within the cylinder 10 in the usual manner.
It will be seen that by the connection between themain shaft 39 and crank shafts and connections between the crank shafts 3e and the slidable valve members 26 and 27, said valve members will be properly 0perated in opposite directions to bring the intake and exhaust ports 28 and 29 respectively, in-position opposite the inlet and outlet passages 16 and 17 at the proper time.
It will also be understood "hat the intake and exhaust pipes-4.3 and 44. are connected i with the casing 2 at diametrically opposite points and opposite the intake and exhaust passages 16 and .17, respectively.
The intake pipes 43 for the two cylinderswithin the casting 1 are connected, as shown at M), and the exhaust pipes 44 for said cylinders arealso connected, as shown at 46. Likewise, the two water inlet pipes are connected to the single pipe #l'Z/and the water outlet pipes 24. are connected to a single pipe 48.
It Wlll be evident that during 0 eration of the slide valve members 26 and 2 oil from the large oil chambers 7 will pass through the transverse slots 8 and fall upon the upper curved edges of said slide valve members 26 and 27 and gradually find its way to the crank casing 36, thereby thoroughly lubricating the operative parts of the engine.
-It will also be seen that owing to the extremely. simple and novel construction of the various parts and the manner in which said parts are connected, the engine may be readily assembled or taken apart and will be highly eflicient and eflective in use as well as positive in operation. It will further be seen that should any of the parts become worn or broken, they may be readily replaced at small cost.
While-I have shownthe preferred form of my internal combustion engine, it will be understood that minor changes in the details of construction may be made within the scope of the appended claims without departing from the spirit of my invention chamber, one of said curved slide valve members being provided with a slot to accOmmodate the water supply pipe, a water outlet pipe leading through the casing from the water chamber, a piston within the cylinder, means for operating the piston, said casing and cylinder being provided with intake and exhaust ports, said curved slide members being provided with intake and exhaust ports adapted to register with said intake and exhaust ports of the cylinder and casing, and a spark plug carried by said cylinder.
