JACOB S. BAHR, OF NORTH VENICE, AND MICHAEL E. LOGUE, OF EAST ST. IIOUIS, ILLINOIS.
GARIBURETER ATTACHMENT.
Specification of Letters Patent.
Patented Dec. 2 7, 1921.
To all whom it may concern:
Be it known that we, JACOB S. BAHR and MICHAEL E. Looun, citizens of the United States, residing at North Venice, Illinois, and East St. Louis, Illinois, respectively, have invented certain new and useful Improvements in Carbureter Attachments, of which the following is a full, clear, and exact description.
Our invention relates to oarbureter attachments and has for its object to provide a simple device to be attached to the air intake of carburetors which will automatically regulate the flow of air into the mixing chamber.
Another object of the invention is to provide such an attachment with a primary and a secondary air inlet passage to the carbureter, the primary passage being permanently open and the secondary passage being valve contr0lled.
A further objectof the invention is to provide such a device which is composed of few parts, is simple in operation and can be manufactured at lowcost.
Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawing in which:
Figure 1 is aside elevat on of a carburetor with our attachment secured thereto; and
Fig. 2 is a longitudinal section through the attachment: I
Referrin to the drawing more in detail, the numera 1 designates the carbureter havm the air intake passage 2. The cylindrical member 3 is formed with the enlargement 4 adapted to receive an end of the air intake passage or conduit 2. Set screws 5 are provided for detachably securing the attachment to the carbureter.
Located on the interior of the cylindrical member 3 is a web 6 which forms a bearing for the valve rod 7 Also located in the interior of the cylinder 3 is atransverse partition 8 provided with a valve seat 9 adapted. to receive the valve 10 carried by the end of the valve rod 7. A spring 11 encircles the valve rod 7 and is interposed between the web 6 and a nut 11 carried by the rod 7. An aperture 12 is formed in the partition 8 for the purpose of admitting air to the carbureter when the engine is being started.
As the speed of the engine increases the sucv tion through the carbureter opens the valve 10. The extent of movement of the valve '10 varies with the speed of the engine and thereby automatically regulates the amount of air admitted to the carbureter.
Having fully described our invention, what I we claim as new and desire to secure by Letters Patent is:
An air valve attachment for carbureters including a substantially cylindrical member, a partition extending across the interior of said cylindrical member and spaced from the ends thereof, a web also extending across the interior of the cylindrical member and spaced from the ends thereof, a valve rod having its bearing in-said web, a valve on one end of said rod, said partition being formed with a valve seat and an aperture adjacent thereto, an annular ofi'set portion on one end of the cylindrical member providing a shoulder for engagement with a portion of the carbureter and means connected therewith for attachment to a carbureter.
