Nov. 27, 1923 -H. LE V. HORNING INTAKE MANIFOLDYFOR INTERNAL COMBUSTION ENGINES Filed June 4, 1917 Patented Nov. 27, 1923..
HARRY LE VAN BURNING, OF WAUKESHA, WISCONSIN, ASSIGNOR T0 WAUKESHA MOTOR ('30., OF WAUKESHA, WISCONSIN, A CORPORATION OF WISCONSIN. I
INTAKE MANIFOLD FOR INTERNAL-COMBUSTION ENGINES.
Application filed June 4,
T 0 all whom it may concern:
Be it known that I, HARRY Ln VAN HoRNrNo. a citizen of the United States, residing at lVaukesha, in the, county of \Yaukesha and State of Wisconsin, have invented a certain new and useful Improvement in Intake Manifolds for Internallombustion Engines; of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
The present invention relates broadly to internal combustion engines and has particular reference to an improved form of intake manifold for vuse in connection therewith.
In the use of a forked intake manifold the direction of flow of the explosive mixture in the arms of the manifold must be reversed when the cylinders at opposite ends of said arms alternately open and draw in the mixture. This results in a loss of energy topropel the gas and causes a change in at direction as well as a pulsation of the gas column which destroys the homogeneity'of the mixture and unbalances the correct distribution of the charge.
With the errors of the prior art in mind I have designed the manifold of my invention with an object to overcome the defects of the prior devices whereby to maintain a uniform flow of explosive mixture which is of the highest quality and suflicient in quantity to perform the duties placed upon the same, as well as to correctly distribute the charge.
A further object .of my invention is to provide an intake manifold which, while embodying all the improvements of my invention, may be readily applied to an internal combustion engine in place of the manifold now in use, Without material alteration of the engine structure.
I have also provided means for speeding up the mixture as the same passes through the manifold just before reaching each of the cylinder ports.
Other objects and advantages ofv my invention will appear from the following detailed description and the claims, taken in connection with the accompanying drawinip, in whichv igure 1 is a top plan view of an internal device.
1 917. Serial No. 172,623.
' combustion engine showingmy improved manifold applied thereto; and
Figure 2 is a'side elevational view of the same, the manifold being shown in section.
In the drawings I have illustrated the cylinder structure of a standard four-cylinder internal combustion engine, the cylinders being cast en bloc in pairs designated C and C. A common cylinder head H is employed for both pairs of cylinders. The upper ends of the cylinders are jacketed to form the intake and outlet portions to which the intake and outlet manifolds are connected. The construction of the engine proper is standard and need not be dwelt upon further.
The intake manifold of my invention is best shown in Figure 2 and consists of a horizontal conduit section-10 provided with an elbow 11 and a downwardly extending portion 12, the latter being connected to the carbureter 13 or other mixture forming The conduit section 10 is formed with alateral extension 14 onits free end, said extension being connected as at 15 to the jacket of the cylinder block C.
In order to connect the intake manifold to the adjoining cylinder block, a second extension 16 is provided connected at 17 to the jacket of the cylinder block C. The respective bores of the extensions 14 and 16 connect with the bore of the manifold 10 as at 18 and 19, and slightly in advance of the extensions 14 and 16 the manifold is formed with constricted portions 20 and 21 embodying the principle and function of a Venturi throat. In this manner the inertia of the gas. when entering. may be taken advantage of in order to pack. the charge into the cylinder. Itwill be noted from Figure 1 that the intake manifold is spa -ed a sufficient distance from the engine cylinder structure to permit location of the exhaust. manifold.
The manifold of my invention may be readily installed on any standard type of internal combustion engine and embodies broadly the idea of a straight distributing arm receiving an explosive mixture from one end only as distinguished from the forked manifold which receives the charge at the intermediate portion and distributes it to each end. In combination with the straight manifold receiving an explosive mixture on one end only I provide the Venturi or constricted portions which/tend to enhance the efliciency of the device. Of course, it may be desirable in some cases to omit the Venturithroats and therefore I do not limit myself to the use of the same.
While I have shown and described my invention as embodying a specific structure, it is to be understood that I do not limit myself to the details but reserve the right to make changes therein such as do not depart from the spirit and scope of the invention as claimed.
I claim:
1. In combination, an intake conduit section having lateral extensions at various dis tances from the end, said extensions having bores communicating with the bore of the conduit, means to introduce an explosive mixture to one end only of said conduit, and Venturi throats in said conduit one in advance of each of said lateral bores.
2. In combination, a straightiintake manifold adaptedto receive an explosive mixture newness at one end thereof only, a plurality of outlets at various distances from the end along the sides of the manifold for connection to the combustion chambers of an internal combustion engine, the bore of said manifold having constricted portions therein one in advance of each of said outlets.
3. In combination, an intake manifold having a straight distributing arm provided with a bore, a plurality of lateral extensions at various points on said arm provided each with a bore communicating with said first bore, means to introduce an explosive mixture at one end only of said firstbore, said bore having constricted portions therein one in advance of each of the lateral bores, and means to fasten said extensions to the cylinder structure of an internal combustion engine toafi'ord communication between the distributing arin and the combustion chambers of the engine.
In witness whereof, I hereunto subscribe my name this 31st day of May, A. D. 191-7.
HARRY LE VAN HURNING.
