The present invention relates to improvements in internal combustion engines, and aims -.to provide a structure whereby superior economy and power are obtained by the use of a blower feed and a blower exhaust mechanism. 7
Another important object of the invention is to improve upon the valve structure, so as to prevent the loss of power by insuring'the closing of the valve during the exploswe charge.
. Another important object of the invention is to generally improve upon structures of this nature by providing exceedingly simple and. efiicient structures, which will be found thoroughly reliable in: operation, and well adapted to the ends and purposes for which they are designed.
With the above. and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing Figure 1 is aside elevation of an internal combustion engine with the featuresof my invention incorporated therein,
Figure 2 is a longitudinal section through one of the blowers B Figure 3 is another longitudinal section therethrough, taken in a plane at right angles thereto in Fi e 2 and Figure 4 is a detail section through one of the valve structures.
Referring to the drawing in detall, it will be seen that 5 designates the intake manifold, and 6 the exhaust manifold of the internal combustion engine indicated by the numeral 7. The numeral 8 designates one of the timing gears which is in mesh with gears 9 and 10 tively. Blowers A and B are interposed in the manifolds 5 and 6 respectively, and the structures thereof may be more clearly understood by a reference to Figures 2 and 3, wherein one of the blowers is shown in section. Each .blower includes a casing 13 having rotatably mounted therein a hub 14 keyed to shaft 11 or 12. An outlet neck is shown at 15, and an inlet neck is shown at 16. These necks 15 and 16 are substantially diametrically opposed. The neck 16 communicates with the interior of the casing 13, as at 17 whereas the neck 15 does on shafts 11 and 12 respec-' not communicate directly with the-interior of the casing 15, but a conduit 18 is formed about the casing one side leading from the neck 15 and-communicating with the open space commumcatmg-the casing 13 and neck 16. A plurality of blades 19 radiate from the hub 14, and revolve about the axis of the shaft 11 or 12, as the same is rotated through the gear 9 or 10, and gear 8. These blades set up a whirling action so as to.
cause a suction through the neck 16 to set up a current through the passage 18 toward the neck 15. Tn the blower A, the neck 16 is disposed adjacent the carburetor so as to suck fuel upwardly toward the intake valves of the internal combustion engine. The blower B, of course, is just reverse as the neck 16 is disposed adjacent the exhaust valves so as to suck the exhaust gases from the cylmders. In the'blower A the blades 1? engage with the'explosive mixture and aid in further mixing the same and breaking up the particles thereof so as to provide a more efficlent explosive mixture and the mixture is fed into the firing chamber of the c llnders so as to be slightly under pressure, t us causing the fuel in the firing chamber to be considerably compressed upon the compression strokes of the pistons. This greatly enhances the power of the engine. The positive suction of the burnt gases from the cylinders prevent excessive formation of carbon, thus increasing the life of the engine, and also insuring the practical complete exhausting of the burnt gases before the explosive gases are fed therein upon the intake stroke of the piston.
In Figure 4 I haveshown in detail one of the exhaust valves. This valve includes a mush-room head indicated generally by the numeral 21, and including a concavo convex body portion 22 mergin at its edges into a conical flange 23 w 'cfi is adapted to engage with the seat 24. A valve stem 25 extends from the center of the concave face of the mushroom head through the guide 26. Spring means 27 is associated with the stem for normally holding the valve closed on its seat. The opening of the valve is accomplished through the usual manner by a rocker arm or the like. The convex surface of the mushroom head is disposed within the firing chamber, thereby providing a lar er surface for the gases compressed wit 'n the cylinder by the compression stroke of the piston to act upon. Thus, no
power will be lost in the escape of the gases either on the compression stroke of the piston or upon the explosion of the gases.
The exploding gases, of course, will also act upon this larger surface to insure the closing of the valve. Thus no power will be lost in the escape of the gases either on the compression stroke of the piston or upon the explosion of the gases.
It is thought that the construction, operation, utility, and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed by way of example since in actual practice it attains the features of advantage enunierated as desirable in the statement of the invention, and the above decription. It will be apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described the invention, what I claim as new is A blower of the class described including a casing, a pair of necks extending from the casing, an opening in the casing communicating one neck therewith, and a conduit formed about one side of the casing leading from the other neck to said opening, a hub rotatable within the casing and having biades readiating therefrom to set up a whirl for aiding the passage of gas through the conduit.
In testimony whereof I allix my signature.
