T. LIND AUTOMATIC AIR CONTROL FOR CARBURETORS Filed April 12 1924 ing is a specification.
Patented Jan. 20, 1925 UNITED, STATES 1 'rnnononn Him, or TAYLORVILLE, rumors. I
An'romznonm CONTROL non cnnnunn'rons.
To all whom it ma concern:
Be it known t at I, Tnnooonn LIND, a citizen of the United States, residing at Taylorville, in the county of Christian and State of Illinois, have invented new and useful Improvements in Automatlc Air Controls for Carburetors, otwhich the follow- This' invention relates to air control devices for the carburetors of internalcombustion engines andhas for its principal object to provide a novel device for automatically regulating the inlet of buretor, the device being operated by the suction of the engine plistons.
Another ob'ect is t e provision of a device. of this 0 aracter embodying a suction opened damper provided with adjusting means whereby its sensitiveness may be varied relative to the carburetor ad ustment and the suction of the engine pistons, in the case of either new or old motors.
Another object is the provision of a device of this character whichwill act automatically to increase the air supply when the vehicle travels down hill and to perform the reverse operation when the vehicle travels up hill.
A further object is the provision. of an attachment of-this character which will tend to increase the flexibility and smoothness of operation of the engine, to reduce the depositing of carbon by insuring a more perfeet mixture and generally improve the running conditions.
An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to install and adjust, positive and automatic in operation, efiicient and durable in service and a eneral improvement in the art.
Vith the above and other objects and advantages in View the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation of an engine and carburetor showing my device applied,
Fi ure 2 is a cross section on the line 2-2 of Figure 1,
Figure dis a rear elevation partly in section showing the heater and air conduit and Figure 4 1s a detail perspective view.
Referring more particularly to the draw- Application 111m A ril 12, 1924. Serial No. 7oc,1e4.
ings the letter A designates a motor vehicle engine having the usual intake manifold B connected with and leading from the car? buretor C which has an air 1nlet D. E represents the exhaust manifold. 3
In carrying out my invention 1" provide a" heating device or stoveformed as a hood 10 of suitable size, shape and construction dis posed against the outer sideof the exhaust manifold E. This hood is held in place by one of the clamps F whichare provided for holding the exhaust and intake manifolds in heated air to the car- 1 place on the engine. The hood is provided at some suitable point with a small opening 11 for the receptionof one end of the clam F. The numeral 12 represents an arm whic is pivoted to the hood 10 in line with the opening 11 as shown and which is formed with an elongated slot 12 engagin on the engine stud which holds the clamp so as to hold the hood firmly. The lower end 13 of the hood is rectangular in shape and pro longed downwardly.
Telescopically engaged within the rectangular end 13 is an air conduit 14 which is rectangular in cross section at its upper portion but which has its lower portion circular in cross section and of elbow shape as indicated at 15 whereby its lower end ma be engaged within the air inlet opening of the carburetor. Extendingthrough this conduit 14 at a point forwardly of its longitudinal center is a spindle 16 which is forked or slotted and within which is mounted a plate 17 held in lace by a staple or U- shaped clip 18 which passes through the spindle and through theplate with the ends upset or clinched. At one side of the conduit this spindle is provided with a downward extension 19 on which is slidably ad- 'ustably mounted a weight 20 held in place y a set screw 21.
In the operation, it will be seen that the suction caused by movement of the engine pistons will cause the damper plate to swing down into partially open position, the de ree of opening at any certain speed depen ing upon the osition to which the weight 20 is adjusted. Quite naturally the greater the engine speed, the greater thesuction so that at hi h speeds a much larger supply of air will e fed to the carburetor than at low speeds. Even when idling, the device oper.
' ates to cut down on the quantity of fuel necessary, as above discovered by actual experimentation and the device consequently acts as a gasolineec'onomizer in addition to auto matically times.
A very important feature is that the device acts automatically-to control the air when ascending or descending grades. When ascending a grade the extension 19 swings back and there is consequently a? greater pull controlling the air supply at all whichreduces the opening of the damper plate so that the, mixture supplied to the carburetorisjless diluted with air than when running downhill. i. 7
From the foregoing description and a study of thefdrawings itfwill be apparent thatI 'have'thus provlde'cl a simple, inexpensiveand easily installed device forthe purpoSQsp'ecified-which is bound to improve the 1 running of a motor i'to,a. material extent, the devicejbe ng moreover free from any neces sity formanual manipulation other than initial adjustment, relative to the carburetor adjustment and the suction tons.
While I have shown and described the preferred" embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of arts as will not depart from the spirit of t e invention or the scope of the subjoined claim.
I claim: i
A device of the character described comprising a conduit having one end engaged, within the air inlet of a carburetor, a s indle journaled through the conduit and avinga depending extension, a damper plate carried by said spindle. within the conduit and a weight adjustably mounted uponsaid extension, the pivot of the spindle being located forwardly of the center line of the conduit. t
In testimony whereof I afiix my signature.
