UNITED STATES CHARLES DJ; LUKACSEVICS OF NEWARK, NEW. JERSEY, ASSIGNOR T EDMUND LOFIELER, OF NEW YORK, N. Y.
To alliwhomvit may concern:
Be it known that I, CHARLES DEQLUKAG- SEVIGS, a citizen of the United States, re-
. and
at Newark, in the county of Essex tate of New Jersey, have invented new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.
My present invention relates to improvements in internal combustion engines, and its objects are to provide valves of improved construction for controlling the intake or exhaust, or both; to provide a combined valve and ignition device; to provide simple and improved means for operating the valves at appropriately timed intervals; to provide an improved construction and arrangement of the ports and passages for the intake and exhaust; and to provide an engine unit which is so constructed that it may be used alone or a; number of such units may be combined to form an engine of the desired power.
To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claim at the end of the specification.
In the accompanying drawings Figure 1 represents a section taken axially through the cylinders and the valves therefor.
Fig. 2 is a detail sectional view showing a device for holding the valve in coiiperative relation with its seat.
Fig. 3 is a detail view of a cam for operatin the valve.
ig. 4 is a detail view of a member forming part of the device which holds the valve against its seat and which cooperates with the cam to actuate the valve.
Similar arts are desiglnated by the same reference 0 aracters in t e several views.
The present invention rovides improvements which are applicabiii to internal combustion engines generally and, hence, it is to be understood that the difl'erent improvements embodied herein are not restricted to engines of the particular types shown. It is also to be understood that the invention is not limited to the precise constructions shown, as equivalent constructions within siding INTERNAL-COMBUSTION Emma Specification of Letters Patent. Patented Sept. 13, 1921. Application filed June 15, 1915. Serial No. 34,243.
the scope of the annexed claim are contemplated.
Fig. 1 shows certain features ofthe invention as applied to an engine having cyllinders and pistons of different sizes in tandem relation. As shown, the casing 1 is formed with a reltaively small upper cylinder 2 and a relatively larger lower cylinder 3, the casing also having a crank ca se- 4 containing the crank shaft 5, and bearings 6 are provided as a mounting for the crank shaft. Of course, the engine may embody any desired number of cylinder units. The piston for each cylinder comprises an upper! section 8 to operate in the upper cylinder 2, and it has a flange or shoulder 9 to operate in the lower cylinder 3. Packing rings 10 and 11 are provided on the sections 8 and 9 of the piston to insure fluid-tight fit of the piston within the cylinders. A connecting rod 12 connects each piston to the crank shaft, as usual. Preferably, a separately formed and removable head 13 is provided at the top of the cylinder casing, this head usually having a water jacket which communicates with the usual water jacket of the cylinder casing. The head 13 closes the top of each cylinder 2 and it contains the valve and the intake and exhaust passages for such cylinder. As shown in Fig. 1, the head 13 is formed with a conical seat to receive a conical valve 14:, and the head 13 is also formed with an intake passage 16 and an exhaust passage 17. The valve 14 is provided with ports 15 adapted to register or communicate at the proper times with intake ports 16 and exhaust ports 17*, respectively. The valve 14 is preferably formed interiorly with aconical or similar cavity which provides the major portion of the compression and explosion chamber of the cylinder, the lower edge of the valve 14 being flush, or substantially so, with the upper end of the cylinder 2, and thereby permitting the engine to be constructed so that the piston may move up into close proximity thereto, thus reducing the size of the compression and explosion chamber, with the advantage that the burned gases are more completely exhausted from the cylinder and the degree of compression of the explosive'mixture is increased. The valve 14 has a hub or journal portion 18 which extends upwardly through the cylinder head 13, preferably in a line central with the cylinder, and it is provided with means located exteriorly of the cylinder for actuating the valve.
As shown in Fig. 1 and more in detail in the other figures are means suitable for actuating the valves and for maintaining them in cooperative relation with their seats. This consists of a plate 157 fixed to the stem 158 of the valve by a clamping nut 159, and this plate has lugs 160 projecting toward one side thereof and arranged to cooperate with the opposite sides of a suitably shaped rib 161 formed on a cam 162, the latter being fixed to the, shaft 155 or 156. R0-
tation of the cam causes the rib 161 to operate upon the lugs 160 to rock the plate 157 and consequently the valve 152 alternately in reverse directions to control the intake and exhaust of the cylinder. The means for maintaining the valve in cooperative relation with its seat comprises a pair of spring plungers 163 which bear upwardly against the under side of the plate 157, these plungers, however, permitting the necessary rocking movement of the plate.
I claim as my invention In an internal combustion. engine, the combination of a rotatable conical cylinder controlling valve, an actuating member connected thereto having a recess and diametrically opposite circumferential bearing surfaces, a revoluble cam having a rib operative in said recess to reciprocate said member alternately in reverse directions, and springs acting on said bearing surfaces of said mem her to retain the valve on its seat.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
