E. M. MCDERMOTT INTAKE MANIFOLD HEATER Filed larch 1'7, 1922 2 Sheets-Sheet 2 .E' d ward M M "Dermoti Patented Nov. 10, 19525.
UNITED STATES EDWARD M. MGDERMOTT, OF EAST ORANGE, NEW JERSEY.
INTAKE-MANIFOLD HEATER.
Application filed March 17, 1922.
To all whom it may concern:
Be it known that I, EDWARD M. McDan- MOTT, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented new and-useful Improvements in Intakeltlanifold Heaters of which the following is a specification.
This invention relates to a heater for the explosive charge of an internal combustion engine, the general object of the invention being to provide a heater located between the carburetor and the intake manifold and which is connected with the exhaust manifold so that the heat from the exhaust gases will heat the explosive charge.
Another object of the invention is to provide means for introducing air into the intake manifold so that this air will mix with the heated gases, with means for controlling the air supply from the dash.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illus trated in the accompanying drawings and specifically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like cl'iaracters denote like or corresponding parts throughout the several views, and in which Figure l is a side elevation of a motor supplied with my invention.
Figure 2 is a plan view of Figure 1.
Figure 3 is an end view of an engine having the improved manifold.
Figure fl: is a vertical median section through the heater portion of the manifold.
Figure 5 is a section. on the line 55 of Figure l.
In these views 1 indicates a motor, 9 the carbureter, 3 the inlet manifold and l the exhaust manifold. A drum 5 surrounds a portion of the pipe 6 which connects the carburetor with the intake manifold, said drum consisting of the body 7 and the end caps 8 which are screw threaded on the ends of the body. These caps have a snug fit on the pipe 6. Furthermore, the intake pipe 6 of the manifold is provided with spaced collars 6 against which the ends 8 bear so that the casing or drum is held against 1011- Serial No. 544,531.
gitudinal movement on said end 6. A pipe 9 connects the drum with the exhaust manifold 4, and a pipe 10 leads the exhaust gases from the drum to a discharge point.
From the above it will be seen that some of the exhaust gases from the manifold 4 will pass through the drum and escape through the pipe 10, thus these hot gases in the drum will heat that portion of the pipe 6 which is enclosed by the drum so that the explosive charge, passing from the carbureter through the intake manifold, will be heated, thus increasing its explosive qualities.
I also provide means for mixing air with the heated charge, such means consisting of a pipe 11 connected with the manifold at the junction of the same with the pipe 6, the outer end of the pipe having a coupling 12 thereon, which has one end opened and covered with gauze 18. A valve 14 is located in the coupling and this valve is controlled from the dash by means of the connections 15.
Thus the driver can control the flow of air to the cylinders by this valve, it being understood that the suction created by the mo 'ing pistons will draw the air through the pipe 11 into the manifold where it will mix with the heated charge coming from the carbureter.
My invention will make the operation of the motor more effective with less consumption of fuel.
It is thought from the foregoing description that the advantages and novel featuresv of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What I claim is The combination with an intake manifold having a pipe disposed angularly thereto, of a heater drum surrounding the pipe and having inlet and outlet ports therein, caps screwed on the ends of said drum and having openings through which said pipe extends, and means onthe pipe engaged by said caps to prevent longitudinal movement of the drum.
In testimony whereof I alfix my signature.
EDWARD M. MGDERMOTT.
