AIR-SUPPLY DEVICE FOR CARBU RETORS.
Application filed July 20, 1922. Serial No. 576,370.
Improvements in Air-Supply Devices for Carburetors, of which the following is a specification.
The principal object of my device is to provide a simple and economical device which can be readily affixed to the exhaust manifold and the carburetor of a gas engine for the purpose of supplying amixture of warm and cool air to the carburetor, and for causing its thorough mixture before it enters the carburetor.
I know it is old to provide a hood like device for conveying warm air from around the exhaust manifold to the carburetor. I
have provided in connection with such a device an intermediate extension or branch with a tapered inlet to said extension or branch for admitting cool or atmospheric air into said hood for mixture with the warm air, passing therethrough into the carburetor.
I have illustrated one practical embodiment of m invention on the accompanying sheet of rawings, which I will now describe. I
Figure 1 is a side elevation of the exhaust and intake manifolds, and carburetor of a motor, with my invention applied thereto;
Figure 3 is a sectional view of my invention, showing the inner construction and arrangement; and
Figure 4 is an ed e view thereof.
Referring in detail to the drawings, 1 designates the usual exhaust manifold and 2, the usual intake manifold, and 3, the carburetor, of a gasengine.
My invention as here shown for illustrative purposes, comprises a hood-like portion, 4, adapted to fit around one side of the exhaust manifold, 1, as indicated, and having the stem, or tubular portion, 5, the lower end of which is connected to the carburetor, as shown.
Said hood-like portion 4: is-provided with a forked attaching plate, 6, by means of which it is held in place on the exhaust manifold 1, as illustrated in Fig. 1. In the tubular portion 5, of said device, I provide a baffle plate, 7, as shown in Fig. 3. near 'which is a hole 8, over which is attached an extensi on or branch, 9, with which commumcates a tapering member 10, having its outer or larger end open to the atmospheric air, and its smaller end constituting a restricted inlet into said branch or extension, whereby the air is discharged or drawn into said branch through a nozzle like entrance, and expands as it enters the larger chamber of the branch or extension member 9, from which it is drawn through the opening 8, and deflected by the bafile member 7, downwardly to mix with the warm air passing through the tubular portion 5 of the device to the carburetor, 3, as will be clearly seen in the drawing.
In the formshown. I have provided a cover, 11, for the branch or extension member, and have mounted the tapering mem ber 10 within a uniform tubular member, 12.
Thus as the warm air is drawn in under the hood-like member 4, and down through the tubular portion 5, to the carburetor, there is also drawn through the tapering member 10, into the branch or extension, 9, atmospheric air from around the engine, under the hood, which is discharged into the tubular member 5, mixed with the warm air, and fed to the carburetor for mixture with the gasoline. Said hood-like member is also provided with a hole. 13, and with the spacing lugs, 14, whereby to provide air space between the hood and the exhaust manifold, and additional air .inlet through said hole- 13, to said space.
I am aware that changes can be made in my invention as here illustrated without departing from the spirit of the same, and I do not, therefore, limit the invention to the details shown, except as I may be limited by the hereto appended claim.
I claim:
In combination with the exhaust manifold and carburetor of a motor, an air supply device of the character shown and described comprising a hood-like device fitting around the exhaust manifold and connected to the carburetor, and a branch Q r i 1,497,70
