Description
@@t. im E950 M. N. JUDSQN .NATURAL GAS MIXER Filed Feb. 6, 1946 INVENTOR. Mma?! 17). n/zas'on ATTD R N EYB Patented Oct. 17, 1950 UNITED STATE s PATENT OFFICE This invention relates to a natural gas carburetor for use with internal combustion engines.
An object of this invention is to provide a device whereby natural gas or other gas may be used as a fuel in internal combustion engines.
With the above and other` objects in view the invention consists of the novel details of construction arrangement, and combination of parts more fully hereinafter described, claimed and il lustrated in the accompanying drawing in which: Figure 1 is a side elevation of an embodiment of the invention Figure 2 is a top plan view thereof and Figure 3 is a sectional view on the line 3-3 of Figure 2.
Referring more in detail to the drawing the numeral I9 designates the mixing chamber which is provided with a depending neck l2 for connection to the carburetorof an internal combustion The chamber on one end is provided with a threaded circular opening I4 and a collar l5 is provided to receive and lock the supply pipe i9 from a source of natural gas not shown to the chamber. A rotary valve 20 is interposed in the supply line as shown.
A valv-e 22 is pivotally mounted at the opposite end of the chamber by means of a transverse shaft 24 to which the valve is secured by rivets 26, the shaft 24 is bent downwardly at its outer end to form an arm 28 on which is pivotally secured by means of a fastener 29 the curved end 30 of the lever 32, the curved end of the lever 32 isv bent at right angles thereto to form the bracket 34 for mounting the adjusting screw 36 which contacts the arm 28 for the adjustment of the valve 22 and a spring 38 mounted on the screw retains the valve in adjusted position; movement of the scr-ew 35 moves the lever 32 on the pivot 29 so that the valve 22 may be adjusted to fully close the chamber I 9 or permit the valve to allow a varied amount of air to enter the chamber I when the valve 20 is fully closed.
The lever 32 has a link 49 pivoted thereto by means of a pin and cotter key 42 and the lever 32 is apertured at 44 to permit the link to be adjustably connected thereto.
The link 40 is pivotally connected to a lever 46 by a pin and Cotter key 48 and the lever 45 is also apertured at 50 to permit the link 40 tobe adjustably connected thereto. The lever 45 is connected to the valve by means of a fastener l. Thus a proportionate amount of air and gas is permitted to enter the chamber by the operation of the` links and lever. A spring 52 connected to the lever 32 at one end and to a bracket 54'at the other end tensions the lever 32 on the arm 28 so that the lever will movev rear wardly as the screw 38 is backed out of the bracket 34.
In installing the device on an internal combustion engine, the mixer is connected to the carburetor of the engine in place of the air cleaner and connections to the source of supply is made. When the -engine is turned over the intake manifold vacuum is then applied to the air valve 22, which opens, causing the link 40 to swing forcing the lever 46 to open the gas supply valve 20, allowing gas to flow into the miX ing chamber where it mixes with the .proper amount of air entering valve `22 then enters the engine through the regular carburetor. The link 40 can be adjusted on the levers 32 and 46 to insure the proper ratio between the valves 20 and 22.
It is believed that the operation and construction of the device will be apparent to those skilled in the art and it is to be understood that changes in the details of construction, arrangement and combination of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.
Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
l. A device of the character described for utilizing natural gas as a fuel for internal combustion engines comprising a mixing chamber7 a gas supply inlet connected toy one side thereof, an air inlet opposite said gas inlet, a supply line connected to said gas inlet, valves, respectively in said supply line and in said air inlet, levers, respectively mounted on said valves, a link adjustably connected to said levers, a bracket formed on the upper end of the lever associated with said air valve means carried by said bracket for adjusting the lever on said air inlet valve to adjust said air valve with relation to said lever and means for connecting said chamber to a carburetor of an internal combustion engine.
2. The invention as in'claim l wherein means is connected to the lever associated with the air valve and said air valve for tensioning said lever in relation to said valve.
