Original No. 1,360,883, dated November 30, 1920, Serial lo/$02,198, led June 6, 1919.. Application for reissue led October l, 1921. Serial No. 504,772.
To all whom it may concern.-
Be it known that I, WILLIAM A. EDwAnDs, a citizen of the United States, residing at Chicago, in the county of Cook and Statel heavier particles of the lubricating oil which is fed in with the gasolene, condense andA collect in the bottom of the crank case, and
feed intermittently in slugs through the passage leading `from the crank case into the cy inder, which would result. in imperfect explosion and cause uneven running of the en `ne.
ne of the primary objects of this invention is the provision of means for va- 2B porizing the li uids which1 accumulate in the bottom of t e crank case so that they will be fed in the form of va r to the engine cylinder instead of in ric liquid slugs, and thereby the imperfect intermittent explosions are eliminated and a smooth, eilicient and rhythmic operation of the engine is secured. v
Another object of my invention is to further break up and vaporize the explosive mixture in its travel Ibetween the crank case and the engine cylinder so as to thereby increase the efliciency'of the engine.
Still another object is the provision of novel means for supplying oil to the wrist quate lubrication of this wrist pin during operation. My invention and many of its inherent advantages will be readily appreciated by those skilled in the art by reference to the following description when considered in connection with the accompanyin drawings.
eferring to the drawings,-
Fig. 1 is a vertical sectional view, through one cylinder of a two cycle engine embodying my invention; and
pin of the engine crank so as to insure ade-v spark plug, is secured in' position by the usual studs or stay bolts 7 The crank case, designated generally by reference character 9, is of the closed type and 4communicates with the lower end of the cylinder, the crank case, and cylinder being shortly cou led but permitting sufficient clearance `for t e voperation lof the connectingV link or piston rod. W'ithin the cylinder the piston 11 is adapted to be reciprocated by means of the connecting rod 12, which is equipped vat its lower end with a wrist pin 13 fitted into the fly wheel 14 mounted upon the engine shaft 15. For the purpose of insuring a supply of lubricant to the wrist pin, the outer face of the fly wheel is provided with a recess v16 increasing in de th from the center toward the perimeter o the wheel, the circumferential walls of the recess being undercutLas indicated at 17, and adjacent the wrist p-in, the recess communicates with the wrist pin bearing through a duct 18. lVhen the engine is in operation, oil from the crank oase will be thrown by centrifugal force to the periphery of the recess 16 and forced through the duct 18 to the wrist pin bearing, thereby insuring adequate lubrication of this bearing.
The explosive mixture is supplied from a carbureter 10 to the crank case throu h a port 19 located in the'lower portion o the cylinder so that it will be fully opened to admit gas to the crank case when the piston is in its uppermost position, and will be entirely closed by the piston when the piston has moved downwardly a portion of its,
The partial vacuum created in the stroke. crank case by the piston on its upward stroke causes the explosive mixture. to rush inwardly through the port 19 as soon as the pistonclears the port in its upward "travel, and upon downward movement of the pislectin cha ton, this" mixture, trapped in the crank case hyfclosure'of the port 19, will be compressed yby the] lston in the usual manner.
.The-.got
tom yof the crank case is provided with-fapassage 21 which is inclined downwardly; to its junction with thev vertical pas- .-openingthrough the intake port 23 efcylinder. The condensed gasolene,

In order to protect the openings 27 against clogging, I prefer to surround the lowerend of the tube 25 with a screen 28, as shown in Fig. 1-
During the operation of the engine the mixture 'from the crank case will llow under pressure when'the port 23 is open, through the Venturitube and the suction exerted by the tube 25 will cause some of the mixture to ease tending toaccumu flow through this tube. All oil, condensed gasolene, and other liquids from the crank ate in the passage 21 will be drawn into the tube 25 through Vthe ports 27 and will be delivered by this tube into the throat ofl the venturi where they will be thorough] broken up, dissipated and mixed with't e explosive charge 'the lower end fgo'ffpthecpassa'gef21 to the. ^cylinder in'lnlly.fvaporiaedzfcondition, 'I

The burnt gases in the cylinder are ischarged therefrom through tie exhaust port 29 by the force of the incoming charge in a manner which is well understood.
It is believed that my invention and many of its inherent advantages will be understood from the foregoin without further description, but it shoul be obvious that various changes in the structural details disclosed may be resorted to without de arting from the spirit of the invention as d ned in the following claims.
