MIXING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
Application filed February 21, 1927. Serial No. 169,796.
This invention relates to improvements in mixing devices primarily applicable to internal combustion engines. I am aware that devices of the same general nature have heretofore been made which consist broadly of two classes: Those in which the battles are rotatable and those in which the bafiles remain stationary.
In the present invention the mining device is provided with radiating blades so shaped that the whole of the outer margin of each blade extends to the tube, or a sleeve inserted therein, in which they are mounted, and each battle is so shaped that it obstructs direct passage through substantially the whole cross section of the sleeve or tube. Tn this manner I aim to provide a mixing device wherein a swirling centrifugal movement is imparted to all the air and gasoline that passes through it to the end that a thoroughly uniform mixture is obtained and also so that a uniform amount of combustible mixture passes to each cylinder. Moreover the plural arrangement of the battles imparts suflicient movement to the mixture for the agitation to continue until the cylinders are reached and again the spiral formation of one side of each blade causes a slight obstruction by which the travel of the mixture becomes accelerated as its swirling centrifugal movement is increased.
Another object of the invention is to provide a mixing device which will cause the mixture to sweep around its bore so that any drops of kerosene or heavier oil will be picked up and assimilated by the mixture.
A further object of the invention is to provide a easing into which one or more sleeves having battles therein may be inserted so that the number of battles can be more readily changed.
lVith these and other objects in view which will become apparent as the specification proceeds, the invention is hereinafter more fully described with the aid of the accompanying drawings, in which Figure 1 illustrates a side View of a carburetor and a discharge pipe therefrom par tially broken away and a mixing device therein having its casing also partly broken away.
Figure 2 is a plan view of the invention with part of the casing and part of the sleeve broken away.
Figure 3 shows the invention with part of the casing broken away, and a spacer and a plurality of short sleeves therein instead. of a single longer sleeve.
Figuret is an end view of Figure 2, and
Figure 5 shows a development of one of the battles.
Referring to the drawings, 1 designates a conventional carburetor connected to an ordinary discharge pipe 2 through which the explosive mixture passes to an intake manitold. (not shown). 3 indicates a connection from the upper side of the discharge pipe 2 which is sometimes employed as asuction pipe as to a vacuum tank.
My mixing device consists of a tube 4 inserted in the pipe 2; one end 5 of the tube is outwardly flanged to hold the latter in posi tion at the end of the pipe 2 adjacent to the carburetor. and the opposite end of the tube is inturned to form an annular groove 6. In the tube is a removable sleeve 7 having an outward flange 8 at one end which rests against the surface of the flange 5, and the opposite end 9 of the sleeve rests in the annular groove 6. Extending from the end 9 of the sleeve are a plurality of spiral slots 10 which terminate a short distance from the flanged end 8. A number of battles 11 having substantially radiating blades 12 are provided and are usually blanked out as shown in Figure 5. Each blade has one substantially radial margin so flexed that the outer ends of the blades will project through the slots 10, these, outer ends are then folded over as shown at 14- against the periphery of the sleeve. In this manner any desired number of bafi'les may be inserted or removed, as I find that the number required to give best results often differs for more or less similar engines.
In Figure 3 a slightly modified construe tion is shown. In the tube 4- a plurality of shorter sleeves 7 each having a battle therein are employed. 15 designates an annular spacer having no battle therein. The purpose of this construction is to provide a plu- .rality of sleeves 7 each having one battle, so
that any desired number of battles, and sleeves, may be inserted and the balance of the length of the tube filled with a spacer, which latter may be supplied in varying lengths. This enables the number of baffles to be changed with greater ease and quick ness.
In Figure 2 the opening 18 through the tube registers with the outlet to the connection 3 through the side of the discharge pipe 2; sufficient opening through the sleeve 7 is provided through the slots 10. g
It Will be noted. that the insides and their blades are so shaped that they not only divert the course of the mixture and impart a swirling centrifugal movement to it, but they also obstruct the passage of the mixture sn'ficiently to cause acceleration thereto so that the cen trifugal movement becomes increased and is of such intensity that it continues until the cylinders are reached. Incidentally this movement insures the Wiping of the bore of the sleeve by the mixture so that any drops of kerosene or heavier oil that might tend to adhere thereto are picked up.
While in the foregoing the preferred embodiments ot' the invention have been described and shown, it is understood that the construction is susceptible to such modifications asfall Within the scope of the appended claims, and moreover it is understood that this mixing device may beutilized otherwise than in internal combustion engines when so desired.
What I claim as my invention-and desire to secure by Letters Patent is:
1.111 a mixing device of the character described, the combination of a sleeve having a plurality of slots therein, a plurality of bafes transversely arranged in said sleeve, and
a plurality of radiating blades on each baflle,
the outer portions of said blades passing through said slots, and theends oi said blades being secured against the periphery of said sleeve.
2. In a mixing device of the character described, thecombination of a sleeve having a plurality of spiral slots therein extending from one end, a plurality of battles transversely arranged in said sleeve, a plurality of radiating blades on each'baflle, the outer portions of said blades being flexed to pass through said spiral slots, and the ends of said blades being secured aga'ihst the periphery of said sleeve.
3. In a mixing device of the character described, the combination of a sleeve having a plurality of spiral slots therein extending from one end, .a plurality of baflles trans tially so arranged that their blades impart a.
continuous spiral movement to all fluid ing through said sleeve. V
4. In a mixing device of the -character described in claim 3, wherein atube having an inturned end forming an annular groove is provided, the sleeve is arranged in said'tube With one end taking into said annular groove, and the opposite end of said tube has an out Ward flange thereon adapted to bear against the outer end of a carburetor discharge pipe.
5. In a mixing device of the character described, the combination of a tube, a plurality of sleeves arranged onebehind the other in said tube, said sleeves having spiral slots therein, means for preventing the sleeve towards one end of said tube from coming out of said tube, transversely arranged bafiies in said sleeves radiating blades on said trans- Verse battles, said blades having their outer ends flexed to pass through said slots, and the against the periphery of their sleeves.
