MIXING DEVICE.

Application filed August To all whom it may concern:

Be it known that I, HARRY A. VAN VLEGK, a citizen of the United States, residing at Parsons, in the county of Labette and State of Kansas, have invented new and useful Improvements in Mixing Devices, of which the following is a specification.

This invention relates to attachments for internal combustion engines, particularly to mixing devices, and has for its object the provision of a device adapted to be interposed between a carbureter and the intake manifold of an engine whereby to break up the gasoline vapor and thereby render it more highly explosive and consequently more efiicient as a fuel.

An important and more specific object is the provision of a device of this character which is formed as a gasket adapted to be clamped between the flanged meeting ends of the ca'rbureter and intake manifold, the gasket carrying a fine wire screen of peculiar shape through which the gasoline vapor passes and by means of which the vapor is broken up and a more intimate commingling of the gasoline vapor and air effected.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, highly efiicient in use, durable in service, and a general improvement in the art. With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Figure 1 is an elevation of my device,

Figure 2 is a longitudinal sectional view therethrough, and

Figure 3 is a cross sectional view.

Referring more particularly to the draw ings, I have shown my device as comprising a pair of gaskets of a size and shape to fit between the flanged ends of a carburetor and intake manifold, the ends of the gaskets being formed with holes 11 for the passage of the usual bolts, not shown, employed for holding the flanged ends together. These gaskets are of course provided with openings 12 at their centers for the passage of the mixture, Disposed between the two gaskets is a circular piece of wire screen 13 which s 0? sstead t the outer e es of 2, 1921. Serial No. 489,325.

the gaskets and the gaskets are cemented or otherwise secured together outwardly of the edge of the screen 13. WVithin the openings 12 the portion of the screen 13 exposed is peculiarly formed. At this point the screen is pressed into angular shape, as shown, whereby it will be V-shaped in cross section with the vertex of the V formed as a ridge 14 which faces toward the current of I111??- ture. This pressing of the screen results in providing inclined surfaces 15 which of course diverge from the ridge 1%.

When my device is inserted between the carbureter and intake manifold of the en gine it is apparent that when the current of mixture strikes against the screen it will be most efficiently broken up, the gasoline being more intimately commingled with the air whereby a more explosive fuel will be provided which will greatly improve the runnmg of the engine. This V-shaped screen does away with the use of all splitting bars or anything else that might be placed in the center of the vaporizer to break and spread the gas.

Having thus described my invention. I claim:

1. A device of the character described comprising a gasket adapted to be secured between the flanged meeting ends of the carburetor and the intake manifold, the gasket being provided with a central opening for the passage of fuel mixture therethrough, and. a wire screen carried by the gasket and having its portion covering the opening pressed out whereby to be Vshaped 1n cross section with the vertex of the V facing toward the stream of mixture.

2. A mixing device adapted for interpositlon between the flanged meeting ends of a carbureter and the intake manifold comprlsing a pair of gaskets provided with rep;- istering holes for the passage of securiiig bolts and provided with registering central openings, and a sheet of wire sc-reen disposed between the gaskets and covering said opening, the portion of the gauze exposed at. the opening being pressed into angular shape with the vertex formed as a ridge to define diverging inclined portions, the ridge being designed to be disposed toward the current of mixture passing through the device.

In testimony whereof I affix my signature.

VAN VLEGK.
