MIXING DEVICE.
Specification of Letters Patent.
Patented May 16, 19 16.
Application filed m 'i'a, 1912. Serial No. 696,927.
To all whom it may concern:
Be it known that I, AUSTIN citizen of the United States, residing at New York, in the county of New York and State of New York, and in the borough of Manhattan, have invented certain new and useful Improvements in -Mixing Devices, of
application Serial No. 657,106.
The object of my invention is to provide a simple, indestructible, and compact device which will destroy the globular formation of the atomized hydrocarbon, coming from a carburetor or the like, before the same reaches the combustion chamber of the engine.
In the accompanying drawings forming part of this specification, Figure 1 is a perspective view of my mixing device; Fig. 2 is a plan View; Fig. 3 is a sectional view of the gas conduit, showing the mixing device in elevation; Fig. 4 is a view similar to Fig. 3, the mixing device in this case extending downward instead of upward from the pipecoupling; Fig. 5 is a view similar to Fig. 2, but showing diagrammatically the movement of t] e particles of gas; Fig. 6 is a vertical, section of the conduit, showing also the movement of the particles of gas; Fig. 7 is a plan view of a modified form of the device; Fig. 8 illustrates a modified form of the" invention.
Referring to Fig. l, the device consists of the tubular member 1 havingthe vanes 2 and 3. The number, shape and'size of the vanes may vary", depending upon the process of manufacture, application ofthe device, etc. A flange 4 may be provided, as a means of holding the device in position, as shown in Fig. 3. The two members of the manifold, 5 and (3, are secured together, the joint being sealed by the gasket 8 and into which sinks the flange 4.
In Fig. 4, the flange 4 is provided at the top of the device, instead of at the bottom as shown in Fig. 3.
M. WOLF, a
' Figs. 1, 4, 5, 6 and 7 show the device in a form that will impart a, right-handed whirl to the fluid or fluids passing through it.
Figs. 2 and 3, show the device adapted to lmpart a left-hand whirl. The direction of the whirling, one way or another, is
immaterial.
In a preferable form .of construction clearly shownin Figs. 2, 3 and 4, the vanes assume a steep angle with the axis of the tubular member l and present a flat surface to the pass ng fluid or fluids. The object of this construction, diagrammatically shown 1n Figs. 5 and 6, is to cause the globules. of liquid hydrocarbon in the mixture .to impings forcibly against the wall of the fuel conduit. The impact shatters the globules, wherefor they are mechanically broken up.
Fig. 5 shows how the globules are directed against the wall because of the upward and abrupt deflection of the mixture caused by the steep, flat vanes.
Fig. 6 shows the globules entering the device, then being deflected so as to impinge on the wall of the conduit, whereby they are subdivided, in which state they more readily yield to the vaporizing influenceof the air in the mixture because of the increased surface for the same mass. After the impact which is mostly tangential to the inner wall of the conduit, the mixture assumes a whirl'-' ing motion'whereby the whole charge is energetically mixed. As the spray nozzle of a carburetor, or similar device, is usually located inthe center of the mixing chamber of the same, the liquid globules will tend to remain in the center or core of the fuel charge as it passes to the engine. To prevent such an occurrence, or to abort a stationary core in the mixture as it passes through the device, the vanes 2 and 3 in Fig. 2 are shown extending beyond the center of the device, overlapping, so that the vanes will cause an interference in the core of the fuel charge; The two center arrows, in the figure, show this result The interference is then caught up by the main swirl and the whole charge thoroughly mixed. I
Fig. 7 shows a modified form of the device, in which the inoperative portion of the tubular shell is removed, leaving but the vanes 2 and 3. r l
In Fig. 8, 18 is the conduit leading to the engine. Itis cut or slotted in such a manner so as to form'the vanes 19. The member20 inclosesthe conduit 18.
W hat I claim is: I
1. A fuel-mixer comprising a tubular eonduit with longitudinal slits in its upper portion and. having each alternate edge of the portions between the slits bent inward '50 substantially the center of the conduit to provide surfaces against which the gaseous mixture Will impinge.
A fuel-mixer vcomprising a tubular conduit with longituclinal slits in its upper portion and having a part near each alternate edge of the portions between the slits bent inward to substantially the center of masses the conduit to provide surfaces against which the gaseous mixture will impinge.
3. A fuel mixer comprising a tubular conduit longitudinally slittecl in its upper portion along two. lines, and having each alternate edge of the portions between the slits bent inward to ubstantially the center of the conduit to provide two triangular surfaces against which the gaseous mixture will impinge.
In witness whereof I have hereunto set my hand in the presence of two witnesses' AUSTIN M. lVOLF. Nitnesses:
