D. S. DU BOIS. MANIFOLD FOR INTERNAL COMBUSTION MOTORS.
APPLICATION FILED SEPT. 22. 1920.
Patented Oct. 18, 1921.
INVENTOR ATTORNEY UNITED STATES DANIEL S. DU 3015, OF IORTLAND, OREGON.
MANIFOLD FOR INTERNAL-COMBUSTION MOTORS.
Specification of Letters Patent.
Patented Oct. 18, 1921.
Application filed September 22, 1920. Serial No. 411,928.
To all whom it may concern:
Be it known that I, DANIEL S. DU Bow, a citizen of the United States, residing at Portland, county of vMultnomah, State of Oregon, have invented certain new and use- 'ful Improvements in Manifolds for Internal-Combustion Motors, of which the following is a specification.
It is well known that in many internal combustion motors the transverse area of the intake valve chamber is greater than the transverse area of the intake manifold connected thereto, and that thus the incoming gas is allowed to expand as it enters the valve chamber, which expansion cools the gas and causes condensation of the same just prior to its entering the motor cylinder.
The object of my invention is to overcome this difliculty, and the device illustrated and described in this application is designed for that purpose. As will be obvious from the description and illustrations my device may be made an integralportion or part of the intake manifold, but in order that it may be applicable to motors already in existence without requiring alteration of the motor or the manifold it is desirable to make it a separate member of the manifold,
and it is 80 illustrated in theaccompanying drawing.
I accomplish the above ob ect by means of the construction illustrated in the accom-' panying drawing, which is a part of th1sap-' plication for Letters Patent, like charactersof reference indicating like parts throughout the several views thereof, and in which:
Figure 1 is a sectional view of the cylinder head of an internalc'ombustion motor with my device installed therein, andFig. 2 is a perspective view of my'device upon an en-' larged scale.
1 the intake valve chamber is desy 3 and the exhaust passageway by In -Fi ignatedIi A, there being therebetween a wall 5-which will become highly heated by the exhaust gases in passageway 4. The valve seat is shown at 6 and the valve stem guide at 7 while the rocker shaft bearing is shown at 8 and the tappet rod guide at 9-. The intake manifold 10 is secured to thehead by bolts 11 in the usual manner, and my device is secured between the flange of the intake manifold and the head.
My device consists of a flange 12 adapted to receive-thebolts 11 and to be therebyallowed to expand until just be clamped between the flange of the intake manifold 10 and the motor head, and a tube 13 integral with said flange 12 and normal thereto, and opening through the flange. Sald tube 13 is inserted within the valve chamber 3 and secured therein by bolts 11 passing through the flange 12, suitable gaskets 14 being rovided to insure a tight joint between the flhnge 12 and themotor head and also between the flange 12 and the flange of theintake manifold 10. 1
By this means the incoming impinged upon the hot wall 5 just above the intake valve of the motor, and therefore condensation is avoided. Sufficient room must be left between the end of the tube 13 and the wall 5 for the free escape of the gases from said tube, but as a further precaution against condensation I bevel the end of said have condensed rom the gas within the tube 13 and are carried along the bottom of said tube will issue therefrom substantially against the wall 5 and thereby become asified before entering the intake valve 0 the motor. A
It is obvious that the gas intake tube 13 may be made a part of the intake manifold without departing from the spirit of my invention, which is to provide means of re stricting thearea of the valve'chamber to' that of the intake manifold and of conveying the incoming gasthrough the long valve chamber to a point adjacent the hot wall of. theexhaust passa eway and there discharging the gas into t e valve chamber.
' The tube 13 is thus an extension of the i j intake manifold into the valve chamber to a point adjacent the hot wall of the exhaust passageway.
My device maybe made ofany sine, and
constructed of an materials deemed convenient and suita le for. a: device of this character, and while I have illi'lstrated and described a'form of construction found desirable in materializinlg my invention, I wish to includein this app Ication all mechanical equivalentsand substitutes'that may fairly be considered to come within the scope and purview of my invention as defined in the ap ended claim. 4 a
aving disclosed my invention so that others may be enabled to construct and to use the same, what I claim as new, and'desire to secure by Letterslatent is:
In an internal combustion motor, a flange secured between the intake manifold and the motor, and a tube integral with said flange and having a beveled end, the longest portion of said tube extending into the intake cent the wall of the exhaust passageway of said motor.
In witness whereof I claim the foregoing as my own I hereunto aflix my signature in the presence of two. witnesses at Portland, county of Multnomah, State of Oregon, this 14th day of Sept, 1920. I V DANIEL s. DU 1301s. Witnesses: I I
