VAPGEIZER MID MIXER FUR INTERNAL-CQIEBUSTIGN ElVGIEEfiL application filed may 22,

To a]? whom it may concern:

Be it known that l, JOSEPH Asians, a citiresiding at Lima, in the county of All n and State of Ohio, have invented certain new and useful linprovemeilts in Vaporizers and Mixers for internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines, and the primary object of the invention is to provide an improveitl means for insuring the proper and. uniform mixing and vaporizing of the charge prior to the entrance thereof into the cylinders of the engine, thereby insuring a smooth running engine.

Jr nother object of the invention is the provision of novel means interposed intermeliate the intake manifold and the intake )O'is of the cylinders of the origins for in aking up the particles of fuel and insur-' n the thorough mixing thereof with the ai so that when the same is introduced into cylinders the charge will be thoroughly ed and of a uniform character.

further object of the invention is the provision of a novel means for insuring the correct mixing of the charge including a gasket adapted to be interposed between the manifold and the engineblock, and a novel body associated with the gasket formed of wire mesh, the mesh being adapted to break up the globules of gasoline and insure the correct mixing thereof with the air, the said wire mesh also tending to vaporize the mixture prior to the entrance thereof into the engine cylinders.

l further object or" the invention is the provision of an attachment for internal combustion engines embodying a supporting gasket arranged to be positioned between the intake manifold and-the engine block, and a pair of oppositely disposedsemispherical screen housings, the inner semis herical screen housing having a finer mesh than the other housing, the said housings forming a chamber between the same for causing the thorough breaking up of the globules of fuel, the mixing thereof with the air and the vaporizing of the mixture.

A still further object of the invention is to provide a novel fuel vaporizer and mixer for internal combustion engines of the above character, which will be durable and efficient in use, one that will be simpleand 1922. Elerial No. 562,7fi1i.

easy to manufacture, and one that can be placed upon the market at a reasonable cost. With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification. in which drawings:

Figure l is an enlarged fragmentary vertical transverse section through an internal combustion engine with the improved vaporizer and mixer said improved vaporizer and mixer being 4 shown in edge elevation.

Figure 2 is an enlarged diametric section through the improved vaporizer and mixer.

Figure 3 is a fragmentary diametric sec tion through the vaporizer and mixer, showin; a modified form of gasket.

Referring to the drawings in detail, wherein simiiar reference characters designate corresponding parts throughout the several views, the letter A generally indicated an internal combustion engine; and B, the improve-o fuel mixer and vaporizer associated therewith.

The internal combustion engine A can be of any preferred type or character, and has merely been shown to illustrate the use of the improved vaporizer and mixer. As shown, the engine A includes the usual cylinder block 5, provided with an inlet port 6, the control or intake valve 7, and the intake manifold 8. The intake manifold 8 can be bolted or otherwise secured to the cylinder block 5, as at 9. In. connecting the manifold 8 with the cylinder block 5, some form of gasket is generally used in order to insure a fluid tight connection between the said intake manifold and engine block.

It is one of the objects of the invention to provide a combined gasket for insurin a fluid tight joint between the manifold H and the cylinder block 5, and for holding the-fuel mixer and vaporizer in place,

The improved charge mixer and vaporizer consists of a gasket or support 10 and the vaporizer and mixer proper 11. The gasket 10 is preferably made of metal and includes an annular body 15. if desired the body 15 can be made from a single sheet of metal which can be bent to provide the parallel flanges 16 and 17 and the connecting portion in operative position,

18. The flanges 16 and 17 form the means for holding the mixer and vaporizer proper 11 in position, and if so desired, suitable packing, such as asbestos can be placed-be: tween the flanges 16 and 17, but it has been found however, that the material from which the vaporizer and mixer proper is made will act as a packing.

The vaporizer and mixer proper 11 comprises a pair of semispherical bodies 19 and 20 formed of wire mesh of the desired auge. The inner edges of the semi-spherical odies 19 and 20 are provided with outwardly extending annular flanges 21 and 22, which are disposed in abutting relation and passed between the retaining flanges 16 and 17 of the gasket 10. The bodies 19 and 20 form a substantially spherical housing and define a compartment 23 through which the charge will have to pass prior to its entrance into the engine cylinders. The wire screen bodies 19and 20 can be formed of the same gauge mesh if desired, but as shown in the drawings, the body 20 is formed of a smaller mesh than the body 19. The body 20 is disposed so that the same will extend slightly into the intake port or passageway 6 of the engine block 5, while the body 19 formed of the coarser mesh is arranged so that the same will extend slightly into the intake mani fold 8.

When the improved device is laced in position, the bodies 19 and 20 wil completely occupy the passageway for the fuel, thus insuring that all of the vapors will pass there through.

It can be seen that in use, the charge will first pass through the relativel course screen 19 and effectively break up al of the globules of gasoline and insure the thorough mixing of the air with the gasoline. As this charge passes through the finer screen of the body 20, the same will, of course, become more thoroughly mixed. While the mixture is in the compartment formed by the bodies 19 and 20, the same will 'become vaporized to a certain extent.

In Figure 3 of the drawings, is illustrated a modified form of gasket C for supporting the mixer and vaporizer proper 11. This form of gasket C is particularly adapted to be used in engines which require a guide for the packing gasket. It can be seen that the gasket C is provided with outwardly extending guide flanges 25 and 26, which are, of course, adapted to engage the inner surface of the manifold 8 and the bore of the intake passageway 6. This gasket can be made in two sections 27 and 28 between which the flanges 21 and 22 of the bodies 19 and 20 can be clamped. This gasket is adapted to he clamped between the manifold and the engine block 5 in the same manner as the gasket heretobefore described.

From the foregoing description, it can be seen that an improved vaporizer and mixer has been provided for internal combustion engines, which will effectively break up all of the globules of gasoline and thoroughly mix the same with the air, prior to the entrance of the charge into the cylinders of the engine, the improved device also tending to preheat the charge to insure the proper va porization thereof when the charge is introduced into the cylinders of the engine.

Changes in details may be made without departing from the spirit or scope of this invention; but,

I claim:

In an internal combustion engine, the combination with an engine including a cylinder having an intake port and an intake manifold communicating with the cylinder, of a fuel vaporizer comprising a supporting gasket disposed between the intake manifold and the intake port, a pair of foraininous semi-spherical bodies secured to said gasket,

one of said bodies being formed of a finer wire mesh than the other body and disposed entirely within the intake portion, the other body bein disposed entirely within the intake mani old.

JOSEPH ASKINS.
