Application filed June is, ioni- Serial naeeese To all whom it may concern:

Be it known that I, HENBIK C. Strains, a'citizen of the United States, and a resident of the town of Harvey, in the county of (lock and State of Illinois, have invented certain new and useful Improvements in Inwherein noise and vibration are practically v obviated, and all of the working parts are positively driven and operate independently of sp'rings. A.t the present time the most general type of internal combustion engine ,is'that employing puppet valves, and these are objectionable for many reasons, not least among which maybe mentioned the noise accompanyingtheir operation, as well as the inefilcient closing of the respective passages which they control. In the present invention i'clle use of peculiarly efiicient slow moving inlet and exhaust sleeve valves admits a construction employing a small clearance space, thus makinghigh compressions easily obtainable, and insuring an economy of fuel. Another objection to the puppet valve type of motor is that the valve area is relatively small, and further the opening and closing movements of the valves and the admission. of the working fluid are not as rapid as desirable, particularly at high speeds. The construction of my engine has made feasible a most convenient arrangement or parts so that the various mecha 'nisms are instantly accessible.

it is an object of this invention to provide 'a construction afiording an operator an opportunity to instantly examine the operating gear without the necessity of exploring the crank pit as in case of great emergency when used in the air, on land at sea.

It is also an object of this invention to construct an internal combustion engine wherein inlet and exhaust ports are provided atthe upper'end of caches" the cylinders thereof and are controlled. by means'oit s-ieeves slidahly mounted within said cylin- Spccification of Letters Patent.

It is also an object of this invention to nective inlet and exhaustsleeves enema Jury it), 3191? construct an internal combustion sleeve valve engine wherein each of the respective sleeves are slidably mounted within theengine cyl- I inders independently of one another and the engine piston, so that wear, between the re spective sleeves and the piston is obviated.

It is also an object of this invention to v construct an 1nternal combustion engine p r'o vention to construct an internal combustion sleeve. valve engine wherein an improved oiling mechanism is provided for introduc in oil around the sleeve valves.

It is also an object of this invention to construct an internal combustion engine pro vided with .sleeve valves operatingindependently of, and out of contact with, one another by means of valve rods, one slidable.

It is also an object of this invention to construct an internal combustion engine wherein sleeve valves are mounted to control the respective inlet and outlet ports at" the upper ends of the cylinders 30?? the e21 glue, and with water jackets disposed around the cylinders also surrounding the,

respective inlet and exhaust ports acting to maintain practically all parts of the engine at a constant temperature. 1

It is also an object of this invention to construct an internal combustion engine wherein independent sleeve valves are mounted to control the respective inlet and exhaust ports at the upper ends of each of the i cylinders, each of said sleeve valves being provided with a central actuatingfrodgtheh y will rod of one valve extending through that the other, andeach of said rods operated fromsuitablecneans. v

It isa further object of this invention to construct an improved type of internal comhustlon engine. wherein the inlet and ezo haust ports communicate directly-through the walls of the engine cylinders and. are

controlled by independently movable sleeve valves operating out of contact with one another and the piston in thecylinder.

It is finally an object of this invention to construct an internal combustion engine wherein noise is almost entirely obviated and economy in operation is secured, due to the use of sleeve valves mounted directly in the heads of the ei'igine cylinders in a manner permitting a small clearance space. to be attained.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings;

The engine'embraces a crank Ease 1, t-he lower portion'Q, of which is removably bolted thereto, and with hearing members 3.

integrally connected by means of webs at, to the walls of the upper portion 1, of the crank case. Thecylinders in the present instance denoted by the reference characters A. B. and .l), are preferably cast en. 72100 for compactness, although not necessarily so, and around the walls 5. of each of the cylinders, the casting is cored to afford a water jacket 6, which extends around and over the upper portion of the cylinders. A crank shaft 7, is journaled in the bearings in said crank case, and 'is suitably connected by means of'connecting rods 8, to trunk pistons 9, one mounted in each of the respective cylinders of the engine.

Inlet and exhaust ports, denoted respectively by the reference numerals 10 and 11,

ing with the inlet ports 10, of a cylinder,

and the latter-with the exhaust ports 11, thereof. On each of the cylinders of the engine an inlet 14, is formed through the wall 6. of the water jacket communicating with the annular inlet fuel passage 12, andsimilarly an outlet 15. is formed through the opposite all of the water jacket communi eating with the exhaust passage 13. An intake manifold 16, is suitably connected upon the outer walls 6, of the engine with the respective outlets from the manifold registering with the inlets 14, leading to the inlet passages of the cylinders. Similarly an exhaust manifold .17, is mounted on the opposite side of the engine, the respective inlets to the manifold communicating and registering with the outlet apertures 15, from the exhaust passages of the engine.

The firing of a charge of fuel introduced into-the cylinders is effected by means of a spark plug 18, threaded into and through the top wall of each of the cylinders and at one. side thereof. The valve members controlling the respective inlet ports 10, and exhaust ports 11. in each of the cylinders, are independent of one another and each similarly constructed, the inlet valve consisting of a ring 19. integral with a hollow hub 20, and connected thereto by hollow radial arms 21. which con'nnunicate into the hollow hub 20, to receive o-il therefrom and pass the same to the outer periphery of the ring. A

piston ring or packing 22, is recessed into. the outer peripheral surface of the. valve ring to insure a sealing fit thereof over the inletports 10.

A tuluilarvalve'. rod 23, is integrally connected on the hub portion 20, of the valve and extends upwardly through the upper wall of the engine through a suitable packing gland 24. An oil passage is formed within the walls of said tubular valve rod,

said passage at its lower'end communicating laterally with a passage in a cross head 26,

secured on the upper end of the valve rod and supporting an oil cup 27, thereon in a n'ianner to feed oil into the oil passage.

The valve for the exhaust ports 11, is

similarly constructed, and is denoted as a whole by the reference numeral 28. In the latter instance, however, the tubular valve messes i extension 31, which supports an oil cup 32,

the oil from said cup passing through a suitable interior, passage in said arm 31, to the tubular valve rod 29, where it then flows downwardly and into the valve 28: Of

course, any conventional type of 'check valves may be mounted in the oil lines of each of the valves to prevent a reverse fiow' taking place therethrough, but for convenience of illustration such valves have not? been shown. A gudgeon pin 33, extends through said cross head. 30, and serves to pivotally connect thereto the pair of links 34, which, at their upper ends, are connected by means of another gudgeon pin 35, to one arm 36, of a bell crank.

A number of supporting brackets 37 two on each cylinder, are mounted on'the upper or top wall of the engine, and extending therethrough is a shaft 38, on which said bell cranks for operating the exhaust valves of the cylinders are pivoted.

A cam shaft 39, journaled in bearings at each of its ends,'is positioned slightly below at one side and parallel to said shaft 38,

above the cylinders of the engine, and is suitably driven from the crank shaft '2', by means of'a chain or link belt 40. A housing 41, is provided to inclose the cam shaft driving mechanisms to'protect the same from dust and to deaden the noise of operation thereof.

.A pluralityyoi cams 42, are rigidly secured upon said cam shaft 39, one cam for each' cylinder of the engine, each running in a bath of oil, and, as clearly shown in Fig. 10, each of said cams is provided with continuous grooves or slots 43 and 44, respectively, on opposite faces thereof, the groove 43, being for the inlet valve, and the groove 44,,for the exhaust valve. Accordingly, in order to operate the exhaust valve, said hell crank,-having the arm is provided with another'arm 45, which, at its ends has a roller which engages in the groove 44, of

the cam.. Said cross head 26, on the "valve rod for the inlet valve, is provided with gudgeon extensions 46, upon "which are pivotally engaged a'pair of links 47, which, at their upper ends, are connected to one arm 48, of a bell crank by means of a pin 49. Said bell crank is also pivot-ally mounted upon said shaft 38, alongside of the hell crank for the exhaust valve, and is provided. with another, arm 50, which,'at its end, is provided with a roller tracking in the groove 43, of the cam. Fig.1, the annular outlet passages for each= As clearly shown in of the cylinders are larger than the annular inlet passages 13, and this, of course, is to permit ready egress of the burnt gases with as little back pressure as possible. The operation is as follows: The cam shaft:39, is driven by a one to two drive from the crank shaft 7, of the engine, so, that the number of reciprocations of the respective annular inlet and exhaust valves Within the cylinders are only half as great as that of the pistons. Of course the respective cam grooves 43 and 4.4:, in the cams 42, are formed so as to open and close the respective inlet and exhaust ports I of the cylinders to insure the proper cycle exhaust passages cored around the cylin ders within the water'jacket thereof, insures an even temperature of all the Work ing parts of the engine, a pre-heating of the inflowing fuel, and a cooling of the exhaust. Qhe valve gearing mounted on the top of the. engine, is of course duplicated for each of the cylinders, and as a whole is a very simple mechanism, and dueto the fact that an oil supply is carried upon the respective parts of the inlet valve and exhaust valve gearing, a positive oil feed directly to the walls of the cylinders of the engine for the valves is insured. In order to inclose said valve mechanisms from dust and to deaden what little noise of operation there is in this portion of the mechanism, a large cover 51, is connected by means-of hinges 52,.to the top wall of the 'engine and closes over all of said valve gearing, and when access to any part thereof. is desired, said cover may be easily swung back:

Dueto the fact that I use cams provided with cam grooves, the actuating mechanisms for the respective valves are positively I moved or reciprocated ,111 both directions, thus obviating the use of springs, and inasmuch as the extent or amplitude of move vention which may be varied through a wide range Without departing from the principles thereof. I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
