IUTEBNAL-COIBUBTION ENGINE.
Appheation am June 11,
7 '0 all whom, it may concern:
Be it known that I, WILLIAM Hana! Canon, a subject of the King of- Great Britain, residing in West Kirb in the county of Chester and Kingdom 0 England, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the followin is a s ification.
The present invention re ates to an improved internal combustion engine.
An object of the present invention is to provide an engine which will run silently and give a greater efiiciency by utilizing more fully expansion of the gaaesafter explosion.
The invention is more particularly described with reference tovthe accom anying drawing showing in cross-sectional e ovation one form of construction by way of exam is. D
n this engine, the crank shaft 1 drives a counter-crank shaft 2 half its own speed of revolution through gearing 3, 4, and 4". The top of the working cylinder 5 is closed by a piston head 6, the gudgeon pin 7 of which is connected by meansof a connecting rod 8 to a crank pin on the crank shaft 2. This connecting rod 8 has a roller abutment 9 cooperating with a cam surface 10 on a tappet lever 11 pivoted at 12 at the top 'end 0 the piston head 6, and having an adjustable abutment 24 enga 'ng the end of a valve 13 adapted to contro a passage-way 14 in the piston head 6.
The workin cylinder 5 is provided with the usual spar ing plug 15 with an exhaust passage 16 which can be coupled to the usual exhaust pipe and silencer, a passage 17 which can be connected to a pure air supply [in a passage 18 which is preferably connected to a carburetter for the supply of carbutetted mixture. v
The engine can be air or water cooled as desired.
The drawin 19 at the end 0 the explosion stroke in which the exhaust port 16 is almost fully opened and the air inlet valve '18' is about to be opened by the pnessure of the roller abutment 9 and the tappet. lever 11. This valve 13- is arranged too n when the exhaust gases passing throng the passage 16 have attained substantially their lghest. velocity, so that air can pass down through the pas sage 17 and assist in'the scavenging of the lnder, the passage-way 17 beingconnected 'an explosive mixture, such as shows the working piston.
1m. M110. M4,. 1
to a source of air under pressure, for in-,
action between the exhaust port 16 and air inlet port- 17 in spite of the fact that the two pistons are approaching one another. As the piston head 6-moves further inward the passage 14 will register with the passage 18 connected to the carburetter through which asolene vapour will enter. As the piston he be covered and then the valve 18 will automatically close.
A suitable timin of the en 'ne is indicated, by way of ex mple, in which the ordimoves towards its extreme position the port 18 will time, be fed with air due' to the injector nary induction stroke commences at the point 20, the firing stroke at the point diametrically opposite, that is to sa 180 de-. ees away irom the oint-21. ilst the ring takes place at a rout the point 22, an exhaust valve opens at the point 23;
When the ports have reached the angular.
position indicated at 21, that is to say, when the top crank 2 is substantially at 20 de' grees from its top center then the bottom crank shaft 1 will preferably be at the outer dead centre, this being the relative position atthe completion of the ower stroke.
I declare that what I c aim is 1. An internal. combustion engine comprising a cylinder having ports at its upper end, a working piston, a movable piston head in said upperend, a valve controlling a passage, in t e said piston head, means to reciprocate said piston head to control a port in the cylinder by a peri heral edge on 1t and means to automatical y operate the valve in said piston head to control the pasway leading to a second port on the cy inder wall uncovered by said piston head 2. An internal combustion engine comprising a cylinder having threeports at its upper piston therein, a movable end, a working piston head at said upper end, a valve controlling a passage in said piston head oorpmunicating at certain times with one of said ports, means to reciprocate said head to control two upper ports in t cylinder by a peripheral edge on it, and means automatically operate the valve in said piston head to control a assage way leadinguncovered by .the piston head. i 3. An internal combustion engine comhx' ising a cylinder having ports atits ugper 'end, a working piston, a movable piston ead '1n' said upper and, a valve controllin 'a. passage,- in the said piston head, a. or
cip'r'ocabe said Eiston head to control a port in the cylinder y a periphemledge on it and a pin onfsaid crank to 0 rate the valve as it swings in an arc of temple with the crank torepas sag e way laiiing to a secto control the cyl nder wall gmcovered by ondpoi t' on the said pistoh head. In "witness whereof, I have hereunto 15 signed ,m'ymame this 28th day of May 1923, in the prese oe of two subscribing witnesses.
