AUTOMATIC CHARGE-HEATING CONTROL FOR INTERNAL-COMBUSTION E Application -filed october as, 1919'. Serial No. 332,703.
This invention relates to certain new and useful improvements in automatic charge heating control for combustion engines, and is a companion application of one executed of even date herewith; the object being to automatically control the application otheat on the charge delivered to the engine by the amount of vacuum at the throat of the carbureter.
Another object of the invention is to provide a heat control in which a'vacuum chamber is employed having a pipe extending to the throatof the carbureter and provided with a plunger for operating means for controlling the admission of heating fluid to the heating chamber.
Another and further object of the invention is to provide manually operatedmeans for resisting the automatic means in order to allow the heating fluid to pass into the heating chamber for warming up purposes.
With these objects in view. the invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully set forth and pointed out in the claims.
In the drawings:
Figure 1 is a side elevation of an internal combustion engine partly in section. showing the application of my improved construction of automatic heat control.
Figure 2 is a similar view showing the heating chamber disposed around the throttle or mixing chamber of the carbureter, and Figure 3 is a perspective view of the valve for controlling the admission of the heating fluid to the heating chamber.
. In the drawing, 1 indicates an internal combustion engine having an intake manifold 2, to which is connected the carbureter 3. The en us is provided with an exhaust pipe 4, o the ordinary construction, the above description being given so that the operation of my improved construction of my automatic control can be readily understood.
The intake manifold 2, is surrounded by a heating chamber 5 having an inlet pipe 6 connected to the exhaust pipe 4, and an outlet pi e 7, connected to the exhaust pipe 4, in or er to obtain a circulation of the heating medium. The inletpipe -6 is rovided with a valve 8 for controlling the a mission of the exhaust gases, said valve being carried by the stem 9 having a crank arm 10 isting in the throat of the carburetor will control the position of the plunger in the vaccum chamber which in-turn will control the position of the valve so that the admission of the heating medium to the heating chamber will be automatically regulated. As the suction in the throat. of the carburetor increases the valve is closed so as to cut otl' the supply of exhaust gases to the heater. It will be seen by this construction that the admission of the heat-ing fluid is automatically controlled by the changing vacuum existing in the carburetor or gas delivering duct, as the case may be. as I do not wish to limit myself to any particular point of connection of the vacuum chamber to the carbureter or induction pipe; but I have found in practice that good results can be obtained by connect-ing the vacuum chamber to the throat of the earbureter.
An internal combustion engine provided with the control thus far described will in starting, especially if the engine israced, sometime cut off the admission of heating fluid before the engine has warmed up, and
in order to provide means for resisting the operation of the automatic means I provide the valve stem 9 with a pin 17, which is engaged by a shoulder formed on a collar 18 loosely mounted on the stem and provided with an arm 19 having dash-controlled means 20 connected thereto, whereby the driver can adjust the same so as to hold the valve in open position, in order to allow the full volume of exhaust gases to circulate through-the heating chamber, so that the charge in its passage to the engine will be heated quickly.
In Figure 2, I have shown a similar construction with the exception that the carbureter 3' is provided with a heating chamber 5 surrounding the mixing and throttle chamber thereof, and the operation of the manually and automatically heat control is identical as previously described.
From the foregoing description, it will be seen that I have provided an automatic WE lhSUED charge heating control for internal combustion enginesyso constructed that the amount of vacuum existing in the induction pipe or carburetor automatically controls the admission of the heating medium to the heating chamber, whereby the explosive charge will be heated to the proper temperature, in order to obtain the best results.
What I claim is:
