mmmrssm MIXING DEVICE Specification of Letters Patent.
Application filed September 29, 1920. serial No. 413,597.
To all whom it may concern:
Be it known that we, WILLIS A." VAN Voonms and LAWRENCE D. VAN Voonms, citizens of the United States, residin at Gra sville, in the county of Rhea and tate of ennessee, have invented certain new and useful Improvements in Mixing Devices, of which the following is a specification.
Our invention relates to a device for atomizing, vaporizing, and mixing hydrocarbon fuel, for internal combustion engines.
An important object of the invention is to provide a device of the above mentioned character, which will properly atomize and vaporize the liquid fuel, for producing a gaseous fuel having a maximum degree of efiiciency.
A further object of the invention is to provide means for introducing, in proper amounts, superheated vapors or gases, into the presence of the atomized liquid fuel, for producing a vaporized charge of high efficiency, and which will prevent to a considerable extent, deposits of carbon in the engine.
A further object of the invention is to device of the above mentioned character, formed of few and simple parts, and which ma be installed upon the engine without materially altering the construction thereof. I
A further object of the invention is to provide means for effecting a high degree of agitation of the divided liquid fuel, for atomizin'g the same, and subsequently forcing the same through a foraminous surrounding element, for contact with heated gases, traveling around the foraminous element, whereby a most intimate mixture is produced, and the particles of liquid fuel completely vaporized.
A further object of the invention is to provide a device adapted for attachment to the exhaust manifold of the engine, to be heated by the hot gases therein, and adapted to receive therein liquid or vaporized fuel, and water vapor, to thoroughly vaporize and mix the same.
Other objects and advantages of the inprovide a 'vention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification, and in which like-numerals 'are employed to designatelike parts throughout the same,
Figure 1 is a perspective view paratus embodying our invention,
of ap- Figure 2 is a horizontal section taken on line 22 of Figure 1,
Figure 5 is a similar view taken on line 5-5 of Figure 4.
Figure 6 is a vertical section taken on line 66 of Figure 1, and,
Figure 7 is a horizontal section taken on line 7-7 of Figure 6.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 10 designates the cylinder blocks of an internal combustion engine of an automobile, having a radiator 11 and fuel holding tank 12, as shown. The numeral 13 designates a carburetor of any well known or preferred type, receiving liquid fuel, such as gasoline, from a vacuum feed device 14, as is customary.
Our atomizing device embodies a casing 15, having a forward propelling chamber 16 and a larger rear atomizing and vaporizing chamber 17. The chambers 16 and 17 are concentrically arranged and in free communication with each other. A plate 18, having a central opening 19, covers the rear end of the chamber 17, contacting with the casing 15. The plate 18 is arranged between manifold of the engine and the casing 15. while the flange 21 of the outlet of the carburetor, is arranged upon the opposite side of the casing 15, these parts being all securely held together by bolts 22, passing through openings therein, as clearly shown in Figure 2. This construction is advantageous, inasmuch as it provides means for rigidly and securely connecting the parts, and permitting of their proper separation, when desired.
The chambers 16 and 17 are preferably cylindrical, and a rotatable shaft 23 extends centrally therethrough, the outer end of the shaft being journaled with a bearing 24, carried by an arm 25, secured within the chamber 16, as shown. The rear end of this shaft is journaled in a bearing 26, formed centrally upon an inner imperforate plate 27, rigidly secured to spaced legs 28, which are in turn rigidly secured to the outer plate 18, as shown. The plate 27 is spaced from the plate 18, as shown. The shaft 23 may the block 10, adjacent the intake I be driven by. any suitable means, .but'we by meansof a prois preferably 0 the tension of the into the side of the ing a central tubular prefer to drive the same peller 29, rigidly secured thereto, and
mounted in the chamber 16.
The numeral 30 designates a preferably cylindrical foraminous screen element,"
which may be formed of perforated sheet metal, wire auze, or any suitable material. The fprwarf edge of the screen element 30, preferably projects into an annular groove 31, while its opposite edge has a close contactwith the imperforate plate 27.
Arranged within the screen element 30 is an atomlzin fan 32, rigidly secured to the shaft 23, an having blades which are preferably perforated.
The screen element 30 is concentric with-- in the chamber 17, but has a substantially smaller diameter, providing an annular or surrounding passage 33, more clearly shown in Figure 4. A tubular inlet 34 leads into" a passage 33, preferably at a tangent, where- 'by the incoming gases rotate about the screen element 30, as indicated by arrows in Figure 4, and this direction of rotation posite to that of the atomizing fan 32. he volume of gases passin through the tubular inlet 34 is controlle by a spring-pressed valve 36, normally held to its seat 37 by a spring 38, engaging the top of the seat. The spring engages a transverse rod 39, having a central-opening to receive the stem 40 of the valve, and a nut 41 is screwed upon the stem, to adjust the rod 39 thereon, and accordingl regulate spring 38. f desired, suitable means extending to the exterior of the inlet 34, ma be provided to regulate the tension of this spring. The function of the valve 36 is to control the volume of superheated vapors, to be described, which are supplied into the passage 33.
The numeral 42, Figures 1, 6 and 7, designates a heating or vaporizing casing, havportion 43, projecting above and below the bottom thereof. This tubular portion has its lower end screwthreaded into the exhaust manifold 44 of the engine, and the lower end of the tubular portion is open, while the upper end is closed, as shown at'45. Heat radiating fins 46 are'formed in posed radially about the tubular'portion 43, as shown. As more clearly shown in F ig ure 1, a pipe 47 leads into the top of the casing 42, through a nipple 48, and this pipe extends into the tubular inlet 34; A.
reathing or air supply pipe 49 extends casing 42, Figure 7, and preferabl leads into the crank case of the engine, igure 1. A T-coupling 50 leads into the casing 42, Figures 1 and 7, and a liquid fuel or vapor supply i 51, is connected with the lower end 0 t is couplin and leads to the fuel supply tank 12. i
the casing 42, and are dis-.,
va or or water sup 1y i e with the upper end of the 'T-couplin 50, and leads into the upper portion o the radiator casing, to receive water or water vapor therefrom.
he operation of the apparatus is as follows:
in the intake manifold is transmitted to and throu h the casing 15 to the carburetor 13, and t e charge is drawn from retor into the chambers 16 and 17, The charge passes through the chamber 16, rotates the propeller 29, which rotates the atomizing fan 32, at a suitable speed. The charge from the carburetor, consisting of air laden with particles of liquid fuel, pass into the interior of the screen element 30, and are there subjected to the violent agitation or beating section of the perforated fanblades. This serves to atomize the particles of liquid fuel, and more intimately mix them with the air. The imperforate plate 27 prevents the escape of the charge from proximity to the revolving fan 32, and hence the atomizing action is prolonged, the gaseous mixture being finally forced through the-strainer element 30, and entering the passage 33. Bfy passing through the stralner element, a urther atomizing action is obtained. When the gaseous mixture thus treated, passes radially into the pax'age 33, it is met by the circularly travelin in et 34. This superheated gas contains proper amounts of heated and vaporized liquid fuel, such as air, which mixture is effected in the casing 42. The superheated serving to unseat the valx e 36. The atomized charge and superheated gas become intimately mixed at the exterior of the screen element 30, and are drawn laterally from proximity thereto, through opening 19, and through the intake manifold 'of the engine, to' be distributed .to the several cylinders.
Itis to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes'fin the shape, size, and arrangement of parts may be resorted to without departing from the spirit of our invention, or the scope ofthe sub'oined claims.
