MARTIN :WILLIAM LINDGEEN, OF CHICAGO, ILLINOIS.
mrnnnan-comnns'rron ENGINE.
Application nieam 14, 1924. Serial No. 726,044.,
This invention relates to new and useful improvements in an internal combustion engine, and more particularly to an engine of this character wherein the usual cam shaft 6 is eliminated in the operation of the timing of the explosion. The main object of myinvention is the provision of an internal combustion engine so constructed as to elimi nate the provision of the usual cam shaft, 1 which operates the timing of the engine for regulating the explosions.
Another object of the invention is the provision of an internal combustion engine of .the above character which comprises com.-
1 paratively few parts so as to reduce the cost of production with an increase in power and s eed due'to an elimination of the usual rag through friction.
. With the above'and other objects in view,
the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set' forth, pointed out in the claims and shown in the which:
Figure 1 is a longitudinally sectional view of an engine constructed in accordance with myinvention showing the intake valve open accompanying drawings, in
for admitting the explosive mixture into the.
cylinder, v Figure 2 is a similar view illustrating the position'of the piston after-theexplosion has taken place and at the beginning of the ex haust, and
] v Figure 3-is a similar view showing the exhaust taking place and the piston-returned prior to another explosion.
In constructing an internal combustion engine of my improved ty e various numhere of cylinders can be used for the purpose of illustration.
nected to the usual crank shaft 1 of means of the piston rod 2. The outer end of the piston rod2 is connected to the iston 3 in any of less diameter than the cylinder 4 leaving an annular space 7 within the cylinder en- Lcircling around the piston.
I have disclosed in tlie ac-, companyingdrawings on one cylinder con.
Movable within the space 7 is. a sleeve 8 which controls the outlet of the exhaust and disposed between one end of the sleeve 8 and the head 5 is a coil spring 9, the other end of the sleeve 8 resting upon an annular flange 10 formed on the base 11 and disposed within the inner end of the cylinder 4.
The outer end of the cylinder 4 is provided with an inlet 12 through which the gaseous mixtures are admitted to the cyliner and the admission of these mixtures is controlled by means of the valve 12. Fitted into the wall of cylinder 4 for the urpose of exploding the mixtures is a spar plug 1 1.
' The cylinder 4: is also provided for with an exhaust outlet 15 which is arranged at a point ad'acent the inner end of the cylinder.
The piston 3 is provided with a centrally disposed longitudinal openin 16, the inner en of ,which extends outwardly at right-angles as at 17 beyond the central ortion of the piston to communicate with t e space 7 between the walls ofthe cylinder and the piston for the purpose of exhausting the exploded mixture.
In Figure I the device is illustrated prior to an explosion, the gaseous mixtures en-' tering the o en inlet 12 and accumulating within the c amber 18 between the piston head5 and the outer end pf the cylinder. As the mixture is exploded, as illustrated in Figure 2, the Valve 13 is forcedto a closed position while the toward the other en of the cylinder.
(piston 3 is reciprocated I This movement will bring the angular end 17 of the opening 16 into registration with recess 19 formed in the flan e 10 and which is disposed directly beneat the inner end of the sleeve 8, thus, as the exploded mixtures pass inwardly through the opening 16, the force of the explosion will bear against the inner end of the sleeve and force the same outwardly against the compression of the spring 9, after the spring has been compressed and the greater portion of theexploded mixture passed thru the opening 16 to the inner end of the piston, it will cause the tension of the spring to return the piston to its intake position as shown at Figure 3, the sleeve 8 moving outwardly with the piston and uncovering or opening the exhaust o ening 15 permitting the escape of the use gases. It will be apparent from this that after the piston has reached its intake position shown in Figure 3 and the used gases are exhausted the tension of the spring 7 will return the sleeve 8 to its normal position closing the exhaust port so that as soon as another explosion takes place the piston and sleeve will be in the same position prior to the previous explosion or in the position shown in Figure 1. j j
Fromthe foregoing it will be apparent that l have provided a simple and efiicient used on motor Vehicles and the like and which will eliminatethe usual cam shaft for controlling the timing of the engine.
\Vhile I have shown and described the preferred embodiment of my invention, it
will be understood that various changes and alterations may be made without departing from the spirit of thefinvention or the scope of the appended claims; I
Having thus described my invention, what I claim is: j v
1. An internal "combustion engine 1nclud-' ing a cylinder having an exhaust port adjacent its inner end and an intake portadjacent its outer end, a piston movable in the cylinder and having a .body'portion in spaced relation with the inner walls-of the cylinder and having a head portion in reciprocal engagement with the inner walls and having a passage formed therein adapted under certain conditions to communicate disposed between the body portionot the piston and the inner walls of the cylinder and movable under force of an explosion in a'certain direction to open communication.
between the passage .and the exhaust port.
2. An internal combustion engine includ ing acylinder having an-exhaust port adrocal engagement with'the inner walls and having a passage formed therein adapted under certain conditions to communicate direction. with the exhaust port, and a sleeve valve with the exhaust port, a sleeve valve movable in thecylinder under force of anvexplosion and disposed between the body portion of the piston and the inner walls of the cylinder adapted under certain conditions to open communication between the passage and the exhaust port, and a resilient member surrounding the body portion of the piston internal combustion engine which can be and disposed between the head portion thereofand an end of the sleeve valve. 3. An internal combustion engine including a cylinder having an exhaust port formed therein adjacent its inner end and. an intake port formed therein adjacent its outer 6 end, a piston movable in the cylinder and having a body portion of a diameter less than the inside diameter of the cylinder and a head portion frict-ionally engaging the inner walls of the cylinder and having an opening formed centrally therein with an in nor end thereof adapted under certain conditionsto communicate with the exhaust port,
a sleeve valve disposed in the annular chamher" and movablein a certain direction under force .of an explosiornto open communication betweenthe passage 'and' the exhaust port, and a coil spring between the head portion and an end of the sleeve valve adapted to resist movement of the sleeve valve in said 4. An internal combustion engine includf ing a cylinder having an exhaust port and an intake port, a piston movable in the cylinder in spaced relation with thewalls thereof andhaving a head portion frictionally engaging said inner walls and having a passage formed therein adapted under oer: tain conditions to communicate with the exhaust port, and means disposed in the space between the piston and inner walls movable in a direction under force of an explosion to open communication between the passage and the exhaust port.
In testimony whereof I affix my signature.
