INTERNAL-COMBUSTION ENGINE.
Specification of Letters Patent.
Patented Nov. 13, 191'7.
To all 'whom z't may concern:
Be it known that I, RoY NV. IDE, citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a certain new and useful Improvement in Internal-Combustion Engines, of which the following is a full, clear, concise, and exact description.
My invention relates to internal combustion engines and is an improvement upon an engine which employs a rotating valving cylinder within an engine cylinder and a piston Operating in the valving cylinder, the valving cylinder being provided with a closed head that receives the force of' the eX- plosions that occur between this head and the piston, the engine cylinder also having a closed head adjacent the closed head of the valving cylinder.
It is the main object of my invention to provide facility for lubricating the outer or upper engaging surfaces of the valving cylinder and engine cylinder and at the same' time increase the 'efiiciency in engines of this type. In carrying my object into efliect I provide freedom for the flow of lubricant between the aforesaid heads of the engine cylinder and valving cylinder whereby lubricant may fiow from this space and preferably also to this space to lubricate the engaging adj acent surfaces of the engine cylinder and valving cylinder. To afford this freedom of flow for the lubricant I provide a vent passage from the space 'intervening between the aforesaid cylinder heads. I
' find that the provision of this vent materially increases the efficiency of the engine as compared with the efiiciency of a similar engine but lacking the vent. This Vent desirably communicates with the crank pit or crank case, particularly where the lubricant is supplied from the crank case to the space between said cylinder heads, it being preferred to convey the lubricant to the space between the cylinder heads by way of the intake port of the engine cylinder. As I have practised my invention the lubricant is carried in the form of vapor fromvthe interior of the crank case by way of a pas- Sage that communicates with the said intake port, the lubricating oil being put in the form of vapor and carried by the flowing air to the intake port by mechanism of the engine which is within the crank case.
I will explain my invention more fully by reference to the accompanying drawings and in which Figure 1 is a sectional ele- Vation on line l-1 of Fig. 2 but with the piston and valving cylinder in different positions; Fig. 2 is a view on line 2 2' of Fig. 1; and Fig. 3 is a sectional plan view on line 3-3 of Fig. 2, Figs. 1 and 2 being some- 'what irregular to/have them respectively innected at 4 with the piston 5. A valve cylinder 6 is rotated in some suitable way as by means of a pinion 7 operated at suitable speed by some engine driven portion, this pinion engaging a spur gear 8 upon the lower end of the cylinder 6. The valving cylinder may be provided with ports 9 to control the admission of carbureted air or other gas through the intake port 10 in the cylinder 11 in which the valving cylinder rotates and also to control the passage of gas through the exhaust port 12 in the cyllnder 11. The cylinder 11 is desirably pro- Vided with a jacket 13 for 'the reception of cooling fiuid. This jacket is carried upon the upper end of the crank case 14 that contains lubricating oil 15 and which has an annular step 16 at its upper end' upon which the lower end of the valving cylinder turns.
An oil pump is shown whlch includes two meshingpinio- ns 17, 18 that operate to withdraw oil from the oil pit and force it upwardly through the passages 19 that 'lead to the various bearing surfaces that are to be lubricated. Oil leaves certain of these bearing surfaces above the level of the lubricating oil 15 as indicated at 20, and the operating parts of the engine within the crank case serves to fan the oil as it leaves these bearings to produce a mist. Air is admitted to the crank case through the breather 21 or other intake openings or passages and a part of it is discharged from the crank case through the passage 22. This passage, in the form of the invention illustrated, communicates with the carbureting or mixing Chamber 23 to which gasolene or other fuel is led from the nozzle 24 of a suitable form vshowing the preferred embodiment thereof of carbureter. The air rising through the Communlcates with the port 10. A portion of the lubricant carried by the Carbureted air finds passage into the space between the heads of the engine and valving Cylinders and in passing to this space rlubricates the adjacent engaging surfaces of these cylinders. Hitherto this lubricant has been trapped in the space between the heads of the engine and valving cylinders and 'became baked leaving a solidifiedO deposit which choked the space between these cylinder i heads and retarded the flow of the lubricant to such space, whereby the proper lubrication of the adjacent portions of the engine 'and valving cylinders was interfered with.
I prevent the trapping of lubricant in this space by promoting the fiow `of lubricant therethrough, a result which is accomplished by providing a vent passage 26 that Communicates with such space and which aifords the free flow of lubricant therefrom.
In 'the referred embodiment of `the invntion this passage Communicates with the Crank pit' so that the lubricant which is passed from ,the space between the cylinder heads is returned to,the Crank case. The
manner in which the lubricant findsaccess to the space between the cylinderheads will be understood by those skilled in the art, it being known that some of the oil will be deposited upon the rotating valving Cylin'- der in the zone of its ports and will work its way upward through the slight Clearance both filed February 19, 1917. The first of these two co-pending cases relates to the carbureter, while the other case is based upon features of construction that are inclusive of the breather 21, the passage 22; the valve mechanism and engine Controlled means for Controlling the flow of fuel; and the provision of a sleeve for maintaining separation between Chambers that contain lubricant and fuel.
VVhile I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following:
1. An internal Combustion engine including an engine cylinder; a rotating valving cylinder provided with a Closed head receiving the force of the eXplosions and located within the engine cylinder which has a head adjacent the head of the valving cylinder,
there being space intervening between said cylinder heads; a piston within the valving cylinder; a shaft; a Crank connected with the piston and shaft; and a lubricant Containing Crank case, passage intervening between the lubricant Containing portion of the crank case and the engaging portions of said Cylinders that are adjacent their heads for conveying lubricant to such portions and to the space between said heads, there being a vent communicating with the space between said cylinder heads.
2. An internal combustion engine including an engine cylinder; a rotating valving cylinder provided with a Closed head receiving the force of the explosions and located within the engine cylinder which has a head adjacent the head of the'valving cylinder, there being space intervening between said cylinder heads; and a source of lubricant in that must intervene between the valving and engine Cylinders. It is also known that the upward flow of the lubricant is due in part to the pressure to which it is subject during' the compression and expansion strokes of the engine piston.
The other novel features of Construction shown are set forth in my copending applications Serial Numbers 149,571, and'149,572, I,
