'tion of parts hereina BRUCE W. TRAYLOE OF ALLENTbWN, LVANIA.
To all whom it may concern v Be it known that I, BRUCE W. TRAYLOR, a citizen of the United States, resident of Allentown, Pennsylvania, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.
y present invention relates to improvements in internal combustion engines and is designed as an improvement on the form of engme disclosed in Letters Patent of the United States anted to me on the 31st day of July 191% #1,'234,971.
. One object of the invention is to provide an engine with a simple and durable over 1 head valve construction in which is provided eflicient lubricating means for insuring proper lubrication of the various moving parts of theWalve operating mechanism.
Another object is to so arrange the intake passages that the number of joints will be reduced and the passages water jacketed thereby heating the incoming combustible" mixture and gasolene. I
With these and other objects in view the preventing any condensation of invention includes the novel features of con-'- struction and arrangement and combinaer described and particularly defined by the appended claims.
An embodiment of my invention is illustrated in the accompanying drawings in v a which-- Figure 1 is a transvdrse vertical sectional view of my improved engine.
Fig. 2 is a part sectional elevation.
Fig. 3 is a sectional plan of a part of the cylinder block.
- Fig. {is a side elevation partly in section of a part of the cylinder block ,with the head removed, and v Figs. 5, 6, and 7 are detail views.
Referrin by reference characters to these drawingst e numeral 1 desl ates the cylinder casting constructed en Zoc'and which may comprise any number of cylinders,
twelve withsix on each' side bein a desirable number. The cylinders in ividually are designated 1 and within-each pair of cylinders works a double piston 2 provided by'a single pit- The cylinder block head is provided with a central longitudinal cam shaft chamber 5 in which is located the cam-shaft 6 'jour- Specification of Letters Patent.

.naled at or near its opposite ends in suitable bearings 6? 1n the end walls of the cam shaft chamber.
The cam shaft is operated from'the crank shaft through the vertical shaft 7 at the NOV. 30, 1920. i
Each set of brackets carries a longitudinal hollow shaft 9 which is closed at both ends, and which is preferably held stationaryby brackets.
These. shafts support therocker arms 10 which have their outer endssuitably adjustably connectedto the stems 11 and 12 of the inlet and exhaust valves 11 and 12 said inlet and exhaust, valves being located along x the outer. sides of the cylinder block as shown.
The rocker arms are provided with projections or arms 10 which overlie the upper ends of hollow plungers .13 guided in vertical passageways formed in the cam shaft cover 8 and'which bear, at their lower ends, on the cams 6 of the cam shaft.
Oil under chamber 5 from an oil pump of the ordinary or any desired construction such as. commonly used in connection with automobile en ines, through the supply pipe 14'.
rom the oil chamber, 5 a portion of the oil is' diverted to lubricate the contact surfaces of the plungers and/rocker arms and to this end the plungers are provided with smallfoil ports or passages 5 and 5". The oil escaping through these openings will pass onto the head of the engine and some of it will reach the felt washers 15 encircling the valve stem guides, which will lubricate the valve stems through the oil passages :15.
Any surplus oil on the cylinder heads will be returned to the oil sump by way of'the casing of the gears driving the cam shaft.
To effect the lubricating of the rocker arms being pinned to one or more of the certain of the brackets, as for example ,the
filled with oil, and the portions of the shafts upon which the rocker arms are pivoted or journaled are provided with oil passages 9 by which oil passes from the interior of the hollow shafts to lubricate the rocker arm bearings.
The front ends of the shafts are provided with small oil ports through which surplus oil escapes into the gear casing, lubricating the gears on its way back to the sump.
The rocker arms and associated parts are completely inclosed by the dust excluding cover 16 which covers the complete head of the engine.
As above stated the inlet. and exhaust valves are located along the outer sides of i the cylinder head. The exhaust valve chambers communicate by the passages 17 through the side walls of the cylinder head with the exhaust manifolds 18 one on each side.
To supply the combustible mixture to the inlet valve chambersI provide the cylinder 1 which an'elbow 20 may be bolted for carbureter connection.
By' the above construction I provide a very compact arrangement, secure a direct discharge of the exhaust products, eliminate any requirement for an intake manifold,
'provide 'for the heating of the combustible mixture and avoid all danger of condensation of gasolene from the mixture in its pas sage from the carbureter to the inlet valvechambers.
Having thus described my invention what I claimis 1. In an internal combustion engine hav-' ing overhead valves, a closed oil chamber in the cylinder head, a cam shaft rotatably mounted-in said chamber, means for supplying oil to said chamber under pressure, valve operating rocker arms mounted on the cylinder head, and means for conducting oil from said chamber to the rocker arm bearings.
2. In an internal combustion engine having overhead valves, an oil chamber in the cylinder head, a cam shaft rotatably'mounted in said chamber, a cover member for said 'chamber, plungers guided in said cover member and coacting with said cam shaft, valve operatin rocker arms )ivotally mounted on suh cover member and parts bearing on the upper ends of the plungers, oil pusszwes through said plungers for conducting oil to the upper faces thereof,
' and means for supplying oil under pressure to said oil chamber.
' ings.
having 3. In an internal combustion engine having overhead valves, an oil chamber in the cylinder head, a cam shaft located therein, a cover member having vertical guide openings, plungers mounted in said openings and coacting with said cam shaft, a hollow shaft supported by said cover member, means for conducting oil from said chamber to said hollow shaft, rocker arms pivoted on said hollow shaft, oil passages through the hollow shaft for lubricating the rocker arm bearings, and means for supplying oil under pressure to said oil chamber. p
4. An internal combustion engine having two rows of cylinders and a longitudinally disposed oil chamber arranged centrally of the head thereof, a cam shaft mounted therein, a cover member for said chamber having guide openings above said cam shaft, plungers working in said guide openings and coacting with said cam shaft, a pair of shafts carried by said cover member, rocker arms journaled on said shafts and having parts overlying the upper ends of the plungers, means for supplying oil to said chamber under pressure, and means for conducting oil from said chamber to the rocker arm bearmgs. 5.

An internal combustion engine having two parallel rows of vertical cylinders and a single cylinder head, with inlet and exhaust valve chambers located near the outer side of each row, exhaust ports opening directly outwardly through the outer sides of the cylinder heads, longitudinal intake passa es located in the head between the rows 0 inlet andexhaust ports and having branches leading to the inlet valve chambers, and means for leading the combustible mixture to said inlet valve chambers.
7. An internal combustion engine having two parallel rows of vertical cylinders and a single cylinder head with inlet and exhaust valve chambers located near the outer side of each row, exhaust ports opening directly outward through the outer sides of the cylinder heads, longitudinal intake passages 10- cated'in the head between the rows of inlet and exhaust ports and having branches leading to the inlet valve chambers, an intake port in the side of the cylinder block below the head, and independent intake ducts leading inwardly and upwardly from said intake port to said intake passages.
