HASSEL D. ROBINSON, or WASHINGTON, DIS RICT OF COLUMBIA.
FUEL-MIXING DEVICE.
Application filed January 7, 1927. Serial No. 159,637.
This invention relates to a-fuel mixing device adapted to be mounted between a carbureter and the intake manifold of an internal combustion engine. When a carbureter has unobstructed communication with the intake manifold of a motor, the charge of fuel passing from the carbureter through the manifold contains a portion of gasoline which has not been properlyatomized. It has, therefore, been proposed to place a screen between the carbureter and adjoining end of the manifold so that the free gasoline must pass through the screen which will cause it to be broken up into fine particles. This has proved satisfactory to a certain extent but it has been found that it is difficult to obtain an air-tight joint between the carbureter'and intake manifold.
Therefore, one object of the invention is to provide a fuel mixing device which may be firmly secured between the carbureter and intake manifold without danger of leakage.
' Another object of the invention-isto provide the fuel mixer with a plurality of fuel atomizing screens spaced from each other so that particles of free gasoline which are not properly broken up by one screen will be acted upon and properly disintegrated while passing through the second screen.
Another object of the invention is to prevent danger of the screen or screens becoming detached from or slipping out of proper relation to the disk or body portion of the device. v
The invention is illustrated inthe accom panying drawing, wherein Figure 1 is a View in side elevation showing one of the improved fuel mixerssecured betweena carbureter and adjacent end of an intake manifold;
Fig. 2 is an enlarged view showing the device principally in elevation, a facing sheet thereof being partially broken away;
Fig. 3 is a sectional view taken on the line 33 of Fig. 2;
Fig. 4 is an enlar ed fragmentary sectional view of the devlce;
Fig. 5 is a view showing a modified form of device in elevation, and
Fig. 6 is a sectional view taken on the line 66 of Fig. 5. V
The fuel mixer constituting the subjectmatter of this invention is intended to be mounted between the outlet neck 1 of a carbureter 2 and adjoining end of an inlet manifold 3. The adjoining ends of the carbureter neck 1 and intake manifold are formed with collars 4 and 5 having openings provided therein to receive the securing bolts B and the fuel mixer conforms to the contour of the collars 4 and 5 and includes a body portion or disk 6 having its end por tions formed with openings 7 to receive the bolts B. It will thus be seen that, when the device is fitted between the carbureter and intake manifold and the-bolts inserted and tightened, itwill be very firmly held in place with its opening Sregistering with the fuel passages of the carbureter and manifold. The opposed faces of the disk 6 are formed with recesses 9 which extend about the borders of the opening 8 and constitute countersunk seats in which are received the marginal portions of thescreens 10. The
screens are preferably formed of fine wire mesh and are of such size and thickness that they fit snugly in the seats 9 with" their outer faces flush with the surfaces of the opposed'faces of the disk, as clearly shown in Fig. 4. After the coveringdisks 10 have been fitted into the seats 9, facing sheets 11 which are preferably formed of thin paper are applied to the opposed faces of the disk 6 and glued or otherwise secured thereto. These facing sheets conform to the contour of the disk or body portion 6 and are formed with openings which register with the opening 8 and are of the same diameter. Since the openings in the facing sheets are of the same diameter as the opening 8, the portions of the covering sheets bordering the openings formed therein overlie the marginal portions of the covering sheets 10, as shown in Figs. 2 and 4, and will serve to securely retain the covering sheets in the seats or recesses 9. It should be further noted that since the covering sheets are countersunk in the disk or body. portion 6, the facing sheets 11 will have smooth outer surfaces which will fit flat against the confronting faces of the flanges 4 and 5 of the carburetor and intake manifold. Therefore, when the bolts are tightened, the confronting faces of the flanges 4 and 5 will have fiat contacting engagement with the outer surfaces of the facing sheets throughout the entire areas thereof and, there will be no danger of leakage due to a ti ht joint not being formed. It should'be further noted that the screens are prevented from'moving out of their seats and, therefore, cannot accidentally slip out of proper covering relamodified form of the invention.
tion to the openingS and also that there will be no danger of suction causing them to be dislodged. Since the screens are held in spaced relation to each other bythe portion of the disk or body 6 between the seats "9,
particles of free gasoline passing from the 1 carbureter must pass through the two screens in order to enter the intake manifold and these particles of gasoline will, therefore, be acted upontwice and will be broken up and a properly atomized charge of fuel insured.
In Figs. 5 and 6, there has been shown a portion or disk 12 is of a different configuratlon from that shown in Fig. 2 but 18 formed with bolt-rece1v1ng openings 13,001-
responding to the openings 7, and with a fuel passage or openings 14, corresponding to the About the openings 14 are formed recesses or seats 15, corresponding to the seats '9, and the opposed faces of the disk 12 are covered with facing sheets 16,
corresponding to the facing sheets 11. The
The body portions of the facing sheets 16. By having the screens formed, as shown in .Fig. 6, the device may be applied to a carbureter having a butterfly valve so disposed in the outlet neck thereof that it would be liable to strike one of the screens 10 and prevented from being properly opened or closed.
Having thus described the invention, I claim:v
A fuel mixer comprising a body adapted to be gripped between compan-ionportions of a carburetor and intake manifold and having opposed flat faces, said body being formed with an opening. constituting a fuel passage and having its opposite faces formed with recesses extending about themargins of the opening and coi istituting seats, gauze disksspaced from each other and covering opposite ends of said opening and having their marginal port-ionsfitting snuglyinto and completely filling said sea-ts, the outer.
surfaces of said disks being flush with the faces of said body, and facing sheets completely covering the said faces of said body and secured against the same and overlapping the portions of the gauzefitting into said seats and secured thereon, said sheets being formed with openings registering with the opening in the bod I In testimony whereof I affix my signature.
