Application mea January 9, 19215. serial No.' 1,342.
To all whom t may concern:
Be it'known that I, HENRY P. HEEREN, a citizen of the United States, and va resident ofLake Township, in thecounty ofVVood and the State of Ohio, have invented a new and. useful Internal-Combustion Engine, which' invention isfully set forth in the following specification. y Y
My invention has for its object to provide a valve mechanism for internal combustion engines whereby large port openings, that is, port openings having large cross sectional areas may be quickly opened and closed at'the proper times in the cycle of operations-of the engine, and which are operated by the ordinary cam shaft of the engine. The valves are so constructed Vthat the passage ways to and from the engine forming the intake, vand exhaust passage the following description and upon examiso that by slight rotation of the valves 9 Ways are operated to their full extent by a very short movement of the valves and yet produce yopenings of a large crossv sectional area for the admission. of vapors on the one hand andthe exit of ,exhaustgases on the other. The invention also provides features and advantages that will `appear. in
nation of the drawings.
The invention ma be contained in internal combustion engines of different forms'.
Toillustrate a practical application of the.
invention and topresent a description thereof in detail, I have selected an engine containing the invention` as an example of the differentembodiments of my invention, and shall describe it hereinafter. The engine selected-as an example is shown in the vaccompanying drawings.V Y
The engine 1 has a head 2 that may be located onthe cylinder block 3 of any of the well known types of internal combustion` engines. The cylinder block 3 is provided with the cylinders 1, in which are'located the pistons 5. The head 2 vprovided with spark plugsv 6 thatrignitethey fuel that is drawn into the cylinders and compressed by the pistons in the manner well known in the art. Thefhead2 is'provided withk a water chamber 7 'that communicates with the chamber 8 located in the cylinder block 3.`
The chambers 7 and 8 form the usual watery jacket for maintaining the engine as cool asV may be. v
The valves for controlling the intakeA and outfiow of the gases are located in the head 2. The valves 9 and 10 are cylindrical in form and are located in shells 11 that are formed integral with the head 2 at points above the cylinders 4. They control the flow of the gases through the ports'12 and V13. The interior of the valves 9 communicate with the exhaust manifold 14 for carrying away .the products of combustion while the valves 10 are connected` to the intake manifold 15 and control the flow of the fuel mixt'ure into the ignition chambers 16 located in the head 2 of the engine. The ports 12 and 13 are in the form Vof long slots having, comparatively speaking, a narrow width and thevalves 9 and 10 are provided with the ports 18 havlng a length and width substantially the same as the length and width of the ports 12 Vand 13, and so that when the ports 18 register with the ports 12 and 13 the passage way from the manifolds to the combustion chambers of the engine will be opened, and
and 10 the passage ways will be closed. The
Vand are so kformed as toabut t-he wall of the head. The exhaust valves 9 yare pressed against the -side wall of the head with considerable pressure, owing to the pressure produced at the time that the valve ris opened during the escape of the burnt gases. The wall ofthe head is provided with anvils 19 that are located centrally with respect to the axis of rotation of the valves 9 and 10. The anvils 19 'are' bosses that are formed integral with the side wall of the head. The openings of the manifolds register with the openingsof the cylindrical chambers 9 and 10 and preferably have `diameters at these points larger than the interior diameters of the cylindrical valves.
The side wall 2O of the head made-rehead by means ofthe bolts 2l. The wall 2O forms a `cover for covering one side ofthe head. It forms a chamber in which thel part of the mechanism-forloperatingthe valves isl anvils 19. The projectionshave recesses that communicate with channels 24C that extend alongthe upper sides oit the valves. The recesses 23 are located belowa pipe 25 having openingsthat are located above the recesses 23. The pipe 25 connects with an oil pump andthe voil is fed from theV well of they crank 'shaft casing into the pipe 25, in the manner well known in the art and then dripsthiough the openings 26 into the recesses 23. Vlt flows along the channels 2e and thus lubricates the entire surface o'l the valves9 and l0.
` The valves 9 and 10 are operated by means of the push rods 27 that/are actuated by the cams 28. of the cain 'shalt 29. The projections 22 are provided with recesses 30 in which the upper ends oi the rods 27 are maintained by means of the springs 3i that operate to tilt the projecting parts 22 ot' the i valves 'against the ends Jor the rods 27, the rods being l'ocat'edlon thezopposite sides of the -aires ofthe valves 'from that on which the springs are located. ,As the valves are tilted backand torthlthe oil that 'drips lroni the pipe 25 Works'back inbetween'the surfaces of the valves and their rshells ll. The springs "31 are secured 'in position by' means of the 'knobs 32 that areA located'on the proj ectinggparts 22 of the' valves, land the knobs 33 that are located on plates 34. The yplates 34 rest upon the cylinder'block `3 oit' the engine and aremaintained in their positions by the rods 27 that extend through the plates 34.
Thus by my inventionl have provided an exceedingly simple construction whereby the parts may be'ieadily assembled'fto forni the engine head or f the engine head may be readily taken' apart rfor purposes of examination and of repair.
