ENGINE Filed Oct. 28, 1929 INV NTOR M ATTORNEY having a vacuum pipe 'connecte Patented Aug. 4, 1931 UNITED STATES PATENT OFFICE ERNEST 'IDICKEY, OF DAYTON, OHIO, ASSIGNOR '1'0 DELCO-LIGHT COMPANY, OF DAY- TON- OHIO, A CORPORATION- OF DELAWARE ENGINE Application mm October 28, 1929'. Serial 110,402,831
The present invention relates to internal combustion engines and more particularly to fuel charge forming devices therefor.
One of the objects of the present invention is to provide improved means for supplying an internal combustion engine with a rich fuel mixture when the environment temperature is cold and to vary the richness of the fuel mixture in accordance with environment tem-' perature variations.
One manner of carrying out this idea is to provide a device, respons1ve to environment temperature for maintaining a high level of fuel in the carburetor fuel. chamber when the environment temperature is low and for gradually decreasing the level of fuel in the carburetor fuel chamber as the environment temperature gradually increases;
Further objects and advantages of the present invention will be apparent from-the following description, reference being had to the accompanying drawings, wherein a pre ferred form of the present invention is hereby clearly shown.
In the drawings:
Fig. 1 is a diagrammatic illustration of an internal combustion engine and showing diagrammatically a method of supplying fuel to the'engine carburetor; and
Fig. 2 is a vertical cross sectional view of the carburetor forming a part of the present invention. y 7
Referring to the drawings, the numeral 20 designates an internal combustion engine having a fuel intake 21. The intake 21 is in communication with a passageway 23 formed by a carburetor 24 having one end attached to the intake 21 by screws 25. A casting 27 forming a passageway 28 and having an opening 29 to allow the passage of air from the outside through the passageways 28, 23 and through the intake 21 to the engine 20, is
connected to the opposite end of the carburetor 24 by screws 31. c
Any suitable means may be employed for supplying fuel to a bowl or fuel chamber of the carburetor 24. In the present case I have provided preferably, a vacuum tank 32 connected to a supply tank 33 by pi e 34, and
(i to the engine intake 21'. The tank 32 also includes an outlet pipe 37 connected to a fuel admission 1 port 38 of the fuel chamber 40 of the carburetor 24. It is to be understood, however, that other means may be used for sup lying fuel to the engine carburetor such as, fbr example, the conventional fuel pump.
- The carburetor 24 includes, preferably, a
fuel nozzle 42"extending below the level of fuel in the-fuel chamber 40 and leadin to the passageway 23, and through which t e fuel may be supplied to the engine by the suction created by the cylinders thereof. A throttle valve 45 including a butterfly 46 is adapted to control the passageway 23 to thereby control the speed of the engine 20. Any suitable means may be employed for controlling the throttle valve 45, such as, for example, an engine speed'responsive governor.
Preferably a needle valve 50, disposed within the chamber 40 for controlling the fuel admission port 38 is operatively connected with a float 51 by a'bimetallic thermostatic blade 52. The needle valve is carried by a lever 55 which is ,pivotally mounted at 56 while a stem 58 of the valve 50 is maintained in a vertical position by a guide 60 formed integral with the chamber 40. By this arrangement the float 51 will actuate the valve 50 to shut off the fuel admission port 38 when the level of the fuel in the chamber 40 attains acertain height.
The bimetallic thermostatic blade 52 is rewhen the environment temperature is relatively low a relatively high level of fuel is maintained within the chamber 49 and a corresponding high level of fuel is maintained in the fuel nozzle 42, which level Ihave indicated at 62. Therefore, a relatively rich fuel mixture will be supplied to-the engine 20 when the environment temperature is relatively low. As the environment temperature gradually increases, the thermostat 52 will gradually bow downwardly until the environment temperature remains constant, for example when maximum temperature has been reached, which point may be approximately as designated at to thereby'maintain a lower level of fuel within the chamber 40 and a corresponding level in the nozzle 42 so as to lean the fuel mixture proportions running through the engine. By this arrangement a level of fuel will be maintained at 62 when the float is in the position indicated at 51 in the drawings. While a lower level of fuel which I have indicated at 67 will be maintained when the thermostat bows to the position indicated at 65 and'of course other levels of fuel intermediate the levels 69. and 67 will be attained depending upon environment temperature variations.
From the foregoing it will be noted that I have provided a carburetor for internal combustion engines and have arranged the carburetor in such a manner that when the environment temperature is relatively cold, a relatively rich fuel mixture will be supplied to the engine, and have arranged for gradually leanmg the fuel mixture for the engine as the environment temperature gradually increases. By this arrangement the engine will be supplied with the proper fuel mixtures at all times.
While the form of embodiment of the invent-ion as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
hat is claimed is as follows:
1. A carburetor for internal combustion engines comprising, in combination, a fuel chamber for the carburetor; and means including a thermostatic element for controlling the admission of fuel to said chamber.
2. A carburetor for internal combustion engines comprising, in combination, a fuel chamber for-the carburetor; and means ineluding a thermostatic element responsive to environment temperature for controlling the admission of fuel to said chamber.
3. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port; a valve for controlling the port; and means including a thermostatic element for controlling the valve.
4. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port, a valve for cont-rolling the port; and means including a thermostatic elementresponsive to environment temperature'for controlling the valve.
5. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port; a valve for controlling said port; a float in said fuel chamber; and means including a thermostatic element operatively connecting the valve with the float for controlling the valve.
6. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port; a valve for controlling said port; a float in said fuel chamber; and means including a thermostatic element responsive to environment temperature operatively connecting the valve with the float for controlling the valve.
7. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port; a valve for controlling said port; afloat in said fuel chamber; and means responsive to environment temperature. operatively connecting the valve with the float for controlling the valve.
8. A carburetor for internal combustion engines comprising, in combination, a fuel chamber having a fuel admission port; a valve for controlling the port; means including a thermostatic element for controlling the valve, said means being responsive to environment temperature variation to vary the level of fuel in the fuel chamber.

10. An internal combustion engine comprising, in combination, a carburetor having a passageway in communication with the engine; a fuel chamber for the carburetor adapted to contain a quantity of fuel; a fuel nozzle extending below the level of fuel in the chamber and leading to said passageway in communication with the engine; and means including a thermostatic element for varying the level of fuel in the fuel chamber.
