MIXER Original Filed Nov. 2, 1928 5W; C. .E- fiae'ley Mo l/3MP Patented Apr. 26, 1932 UNITED STATES PATENT OFFICE MIXER Original application filed November 2, 1928, Serial No. 316,685. Divided and this application filed November 13, 1929.
This application is a division of an application filed by me November 2, 1928, Serial No. 316,685.
The invention provides a mixer of unique construction for combining air and any liquid fuel to produce a gaseous mixture for use in internal combustion motors, furnaces, lighting plants, and other apparatus. The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully de scribed and then more particularly defined in the appended claims.
In the drawings:
1 Figure 1 is a central vertical longitudinal section of a carbureter having the invention embodied therein.
Fig. 2 is an end view of the mixer with a portion of the casing in section on the line 2-2 of Fig. 1, and
Fig. 3 is a top plan view of themixer and its supporting ring.
As shown in Fig. 1, the casingis constructed in sections secured together by screws or bolts inserted through "confronting lugs or other projections.
The body or casing includes'chambers 1, 2 and 3 and passages connecting said chambers, the-"chambers 1 and 2 being connected by a passage 4, the chambers 1 and 3 by a passage 5, while the chambers 2 and 3 are in direct communication. An outlet 6 leads from the chamber 2 and receives a butterfly valve 7 constituting the throttle. A pipe 8 is connected with the outlet 6 to convey the gaseous mixture from the carbureter to the point of use. The air inlet 9 is in direct communication with the chamber 1. A pipe 10 connects one end of the chamber 1 with the usual breather pipe, the end of the pipe having a close fit in the wall of the casing forming the side of the chamber. A rotatable valve 17 normally closes the passage 5 and is movable across the inlet 9, being connected with a control element on the instrument board or otherwise conveniently positioned within reach of the operator whereby to regulate the how from the chamber 1 into the passage 5.
A valve 21 within the chamber 1 controls Serial No. 406,914,
the flow from said chamber to the chamber 2 and is connected at one end to a lever 23.
An ad ustable stop 27 mounted upon the body or casing of the carbureter engages the lever 23 and determines the normal position of the valve 21..
The vaporizer 28 is located within the chamber 3, as shown, but a detailed descrip tion thereof is not necessary to an under- SiZElDCllllQ of the present invention.
Themixer consists of a hollow body or shell of conical formation and of a length approximating the axial dimension of the chamber 2. The mixer is supported centrally within the chamber 2' by means of a plate 43 which is clamped between the sections of the carbureter body or casing. The larger end of the mixer faces the outlet 6 and the smaller end faces the passage 4 to receive the inflowing air therefrom. In the illustrated construction, the body or shell of the mixer is of thin metal which is: longitudinally fluted or crimped to provide passages 44 and 45 which taper throughout their length, the smaller ends being adjacent the smaller end of the body and the larger ends coinciding with the larger end of the said body or shell. The passages 44 open outwardly whereas thepassages 45 open inwardly and they are closed to each other through their entire length, as shown in Figs. 2 and 3. A baffle 46 is located at the larger end of the mixer and serves to arrest the inflow of the air entering the mixer by way of the passage 4 and deflect the same outwardly into the air passages 45. The space surrounding the mixer and formed between it and the outer wall of the chamber 2 is in communication with each of the passages 44 and with the chamber 3 to receive the gaseous mixture from the vaporizer. The passages 44 and 45 alternate and open into the rear end of the mixing chamber 2. The terminal portions of the walls separating the passages 44 and 45 are deflected laterally, as indicated at 47 in Figure 8, to deflectthe outflowing air and mixture laterally to impart a swirling movement thereto to efi'ect a thorough mixing so that a homogeneous gas results to be supplied to the engine to obtain an explosion of maximum force. The rear wall of the chamber is constricted on a curved line, as indicated at 48 in Figure 1, thus gradually forcing the gaseous mixture inward across the paths of the outflowing currents of air from the passages 45. This results in a thorough mixing of the air with the mixture discharging from the passages 44.
The numeral 49 designates a float chamber with which a fuel pipe (not shown) connects to convey the hydrocarbon to the vaporizer, a float in the chamber 49 controlling the flow thereto in a manner well understood in the art. 7 I
When starting the engine, the valve 17 is partly open and the valve 21 is closed. After the engine has warmed up sufiiciently to run freethe valve 21 is opened to admit addltional air. The speed of the engine is controlled by means of the throttle 7 1n a manner well understood. The throttle may be opened to a certain extent without moving the valve 21 and beyond the given point the valves 7 and 21 move together. The inlet 9, outlet 6, chambers 1 and 2 and thepassage 4 are in line, as shown clearly in Flgure 1 of the drawings. The chamber 3 and passage 5 are located below the chambers 1 and 2, thereby admitting of the vaporizer and float chamber occupying a position below a straight line connecting the inlet 9 and outlet When the engine is running, air 1s drawn into the crank case through the breather plpe and air and oily vapor are drawn from the crank case and supplied to the carbureter. The pressure within the crank case 1s not increased and there is aconstant flow of air therethrough to cool the interior and carry oil the oily vapor.
The stop 27 may be adjusted to properly limit the throw of the lever 23 and prevent its overthrow when the throttle 7 is operated by a quick movement or jerk of the throttle lever through wear and looseness of turnbuckle joints and lever connections and which would result in opening the valve 21 too far.
The throttle valve 7 and valve 21 are adjusted so that the throttle valve 7 is slightly open for idle running of engine. The valve 21 then laps over port or passage 4. A furthermovement of the throttle valve 7 of onesixteenth of an inch then valve 21 commences to. open but at a greater rate of speed than the throttle valve 7 When the throttle valve 7 has uncovered one-half of the bore of outlet 6, valve 21 is wide open and lever 23 is against stop 27 or valve 21 is wide open when throttle valve 7 is half open.
The exhaust gases are carried through a pipe (not shown) to the vaporizer to heat the same and then pass off through the pipe 42.
Having thus described the invention, I claim:
1. The combination of a mixing chamber having an outlet at one end, an inlet for air at the opposite end and an inlet for vapor in one side, and a mixer comprising a hollow open-ended body having longitudinally disposed passages in its sides closed to each other through their entire length, some of the passages having open inner sides and the alternate pasages having open outer sides, said body being disposed axially in the mixing chamber.
