Application July 10,
1 Claim.
My invention relates generally to carburetors for internal combustion engines and the like, and particularly to a supercharging carburetor especially arranged for fueling an internal combustion engine of the multi-cylinder type, and an important object of my invention is to provide an extremely simplified and relatively inexpensive supercharged carburetor which is capable of being installed without extensive alterations on conventional internal combustion engines.
Another important object of my invention is to provide a supercharged carburetor of the type indicated which is especially adapted for fueling internal combustion engines involving more than one bank of cylinders.
Other objects and advantages of my invention will be apparent from a reading of the following description in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.
In the drawings:
Figure 1 is an elevational view of the right hand side of an embodiment of the invention.
Figure 2 is a front elevational view thereof.
Figure 3 is a rear elevational view thereof.
Figure 4 is a transverse vertical sectional view taken through the fan casing.
Figure 5 is a transverse vertical sectional view taken through one of the needle valves.
Referring in detail to the drawings, the numeral 5 refers generally to a shaft housing having the packing gland 6, in which housing and in which gland turns the shaft 1 which has on its front end the fan belt pulley 8 and on its rear end the two bladed fan 9 which works within the cylindrical fan housing III, which also constitutes the bowl of the carburetor. The bowl or fan casing is connected by means of a flange H to the rear end of the housing 5. As shown in Figure l the housing 5 may be equipped with a lubrication fitting l2.
The fan housing I is closed and in its rear wall it has a screw 13 arranged centrally therein and provided with a point M which enters a hole l in the center of the fan l6 so as to assist the shaft 1 in centering the fan and the fan shaft and in securing easy running of the fan and quiet action.
The numerals I! and I8 refer to diametrically oppositely arranged openings in the front of the fan casing by which the mixture of air and vaporized gasoline enters the fan housing. A fitting 19 has its rear end connected to each of the openings l 7, l8, and each fitting has a rising portion 20 and a depending portion 2|. Screwed into 1934, Serial No. 734,534
the lower end of the depending portion 2| is the threaded portion 22 of the needle valve seat generally designated 23, which has the nut portion 24 and below it the threaded portion 25 for connection to the gasoline supply pipe 26. Air enters the front end of the fitting l9 through the air intake nipple 2'! which is located just above the upper end of the needle valve seat 23 as shown in Figure 5. The needle valve 28 is closely slidably fitted in the rising portion 20 and has its pointed lower end 29 working in the upper end of the bore 3B of the seat 23 as shown in Figure 5. The upper part of the needle valve has a piston portion 3| which slides in a relatively larger portion 32 of the bore of the rising portion 20. A cap- 33 threaded into the upper end of the portion confines a helical spring 34 into engagement with the reduced portion 35 of the upper end of the needle valve so as to maintain the needle valve normally downwardly pressed to close the seat and prevent entry of gasoline. The upper part of the portion 20 is spirally slotted as indicated at 36 to receive the operating lever 31 which is fixed to the side of the portion 3! of the needle valve so that when the lever 31 is worked in a circumferential direction it will ride on the walls of the spiral slot 35 and either lift the needle valve 28 and open the valve or to permit the spring 34 to seat the valve. Since the valve mechanisms on either side are similar in structural arrangements, the description of one will suflice for the description of the other.
The lower part of the rear wall of the fan casing or bowl of the carburetor is provided with outlet nipples 39, 40 and Al, respectively, which discharge the air and gasoline in properly vaporized and commingled condition under relatively high pressure due to the action of the fan l6 which operates to suck the air and gas through the valves at extraordinarily high speed and pressure and also acts to force the resultant carbureted mixture with corresponding force and speed through the outlets 39, 40, and 4|, which have threaded portions for connection to conduits lead ing to the intake manifolds of the same or of different banks of cylinders of the engine. It will be obvious that the device of the invention will be mounted in such a position that the fan belt pulley 8 will be engaged with the fan belt of the engine and be operated thereby.
Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in materials, and in structure and arrangement of parts, within the spirit of theinvention and the scope of the subjoined claim.
What is claimed is:-
A supercharging carburetor comprising a closed blower casing containing a blower fan, one end of said casing having fuel mixture intakes located eccentrically with respect to the axis of the fan, each of said intakes including a fuel inlet and an air inlet, the opposite end of the casing having supercharged fuel mixture outlet means, said fan being in suction relation to said intakes and in pressure relation to said outlet means, said intakes being provided with fuel and exterior air admitting and proportioning means and comprising a needle valve for the fuel intake, a casing for the valve having a spiral slot and a control lever attached to the valve and projecting through the slot outwardly of the casing to actuate the valve.
