1 Claim.
This invention relates to mixing devices and more particularly to, a gaseous fuel mixing device adapted to be assembled into the intake manifold of an internal combustion motor between the carburetor and the motor.
An object of this invention is to provide a device to intercept the flow of the fuel column and thereby agitate the fuel column to cause the particles of moisture carried therein from the carburetor to more thoroughly break up into their component parts and more readily mix with the air forming a part of the fuel column.
An object of this invention is to provide a simple and efiicient device which may be readily assembled into the intake manifold of any internal combustion motor and which when assembled therein wiil intercept the fuel column and break up the directional flow thereof and cause the fuel column to rotate in reverse directions within itself, thus providing by the simplest form of structure the maximum amount of agitation of the fuel column for the better intermixing of the fuel and air contained in said column and for the breaking up of any particles of moisture which may have been carried from the carburetor in that form.
Another object of this invention is the provision of a device adapted to be disposed within the intake manifold of an internal combustion engine, between the carburetor and the motor. Said member including a plurality of radially disposed fins defining a corresponding series of openings, a further opening centrally disposed in said device and a screen positioned over the various openings defined by said radially disposed fins Our invention possesses other advantages and has other objects which may be made more easily apparent from a consideration of one embodiment of the invention. For this purpose we have shown one form in the accompanying drawing and forming a part of the present specification. We shall now proceed to describe this form in detail, which illustrates the general principles of our invention, but it is to be understood, that this description is not to be taken in a limiting sense, since the scope of our invention is best defined by the appended claim.
The accompanying drawing illustrates the invention in a form we at present deem preferable. Figure 1 is the vertical sectional view showing our device within an intake manifold, the device proper being taken on a staggered sectional line as indicated by line l| of Fig. 3.
Figure 2 is a plan view of the under side of the device.
Figure 3 is a top plan view of said device. Referring to the accompanying drawing and particularly to Fig. 1 thereof, we show our device a positioned in the intake manifold of an internal combustion engine, between the carburetor and the engine.
Said devicecomprises a fiat body portion 4 having two oppositely disposed extensions 5 and 10 6 which are provided with slots 1 and 8. The device is held between the carburetor outlet 9 and the intake manifold I0 as by the aid of bolts II, II passing through the slots 1 and 8 and. the flanges on said carburetor outlet and intake 15 manifold.
The central portion of the body 4 has several sections cut out, as at Ila, leaving a plurality of radially disposed fins I2, l2. Said fins connect said body member and a raised central ring por- 20 tion l3 which has a central opening N therethrough. A screen member I5 is secured to the body member and covers the radially disposed fins and their adjacent openings. Said screen is secured to the centrally disposed ring portion I3 25 as by the aid of a crimp l6 and thus has a central opening. We prefer to press the screen into the body member as shown clearest at I! of Fig. 1.
As has heretofore been stated a central ring 30 portion I3 is somewhat higher than the body portion of the device, and the fins connecting said ring and body are angularly disposed as shown in Fig. 1. In other words, the device projects upwardly within the intake manifold in the form of a frustro-conical spider-like member.
The fins I2, I! are depressed as at l8 Figures 1 and 3, forming a biased ridge l9 and two adjacent angular faces 20 and 2|. 0
In operation the gaseous mixture from the carburetor is diverted at an angle through the screen member l5 and thereby more perfectly atomized, and also the velocity of the gaseous fuel is increased by the aid of the central opening I. The 45 biased ridges l9 and the angular faces 20 impart a spiral movement to the column of gaseous mixture, which still further increased the thorough mixing of fuel gas and air.
In view of the fact that the character of fuels 50 now being used for internal combustion motors is rapidly changing to contain more of the unsaturated hydrocarbons, and also in certain forms of motor fuel there is combined with the refined gasoline such elements as the conventional forms of lead now being used in anti-knock gasolines, it becomes more essential that the liquid fuel be fully vaporized and thoroughly mixed with the air before it reaches the combustion chamber of the motor, therefore we have provided this mixing device to be used for the purposes recited.
It being common to the art to intercept and agitate the fuel column, before the column reaches the air controls, which in this device are the fins 12, I! it has been found, upon reducing this device to practice, that a more efllcient mixture of the fuel column can be obtained from the arrangement in this device, than from the arrangement heretofore common in the art, and for simplicity of construction and to eliminate .wear and tear on moving parts and the consequent upkeep of such moving parts, we have provided the propeller structure comprising the recited fins l2, I! wherein the air directing elements are stationary, and by utilizing the passage of the fuel column thereby, the momentum of the column having suflicient force to cause the fins I 2, I2 to exert the necessary directional force against the column passing therethrough, it was found unnecessary to have moving parts in this device, therefore the construction as disclosed.
With our device, the objections to the conventional mixer having moving parts is avoided, and also the character of the construction of this device wherein the materials used are a non-corrosive and non-rusting character, deterioration of the device by use is avoided, and we therefore claim novelty in the construction and character of this device as disclosed. It will be readily observed that the form of the structure of the device as disclosed in the'drawing will be subject to modification for commercial use to adapt it to be fitted to the various sizes and shapes of intake manifold connections wherein it is designed to be used. Therefore, such modifications as may be necessary to reduce the invention to practice will suggest themselves to those skilled in the art, and to this end we make reservation to make such changes in form and construction as may come within the spirit of the accompanying claim.
We claim:
In a gaseous fuel and air mixing device, the combination of a fiat body portion, radial fins integral with said flat body portion and with a raised central portion thereof, said raised portion having a central opening, a screen superimposed on and having flanges pressed into said flat body portion, said screen covering said raised portion of said fiat portions, and said screen having a,central open'ng corresponding to the central opening in the said raised portion, and biased ridges on said fins adapted to impart a spiral movement to the gaseous fuel and air mixture passing through the openings between the said fins and through the said screen for the purpose of producing a more perfect mixture of the sad fuel.
