FUEL-SUPPLY MEANS FOR INTERNAL-COMBUSTION ENGINES.

Application filed April 23, 1926. Serial No. 104,082.

My present invention has to do with the fuel supply of internal combustion engines; and it contemplates the provision of means adapted to enable an internal combustion engine to develop considerable power and speed with small consumption of gasoline, and this in such manner that but little carbon will be present in the engine.

Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a side elevation showing my improvement properly arranged relative to an internal combustion engine.

Figure 2 is an enlarged vertical section of the liquid container of my improvement.

Figure 3 is an enlarged View taken at right angles to Figure 1, and showing the forward screens of my improvement.

Figure 4 is a detail enlarged longitudinal section showing one of the nonireturn valves in the conduits intermediate of the liquid container and the mounting in which said forward screens are arranged.

Similar numerals of reference designate corresponding parts in all the views of the drawings.

In Figure 1 I show a conventional internal combustion engine 1 having an exhaust conduit 2, and in close proximity to the ex-' haust conduit 2 and in close proximity to the said exhaust conduit 2 I show a hot plate 3 of conventional or any other appropriate construction designed to receive atmospheric air so that such air will be heated by the heat given olt' by the said exhaust conduit 2.

I also show in Figures 1 and 2 the liquid container 4 of my improvement, the said container-4 being provided with a pendent normally closed drain 5 and having in its interior a baffle plate 6 and a screen 7, the latter being preferably of basket form and being fabricated by preference, of appropriate reticulated material. Leading from the hot plate or analogous device 3 to the,

container 4 is a conduit 8, the eduction'orifice of the conduit 8 being disposed below the said bafile plate 6 as shown in Figure 2. The container 4 is adapted'to hold in its lower portion a body of water or other appropriate liquid, water being preferably employed except in extremely cold weather,

atwhich time an appropriate oil may be wed in the container 4 in lieu of water. 9 the container 4 is provided with a normally closed filling conduit, Figure 1.

The scheme of my invention contemplates the carrying of heated atmospheric air lated material, the said screen 11 being preferably of general cone shape and being disposed in th comparatively large-screen 7. From this it follows that en route between the interior of the container 4 and the conduit 10, the saturated air must of necessity pass first through the screen 7 and then through the auxiliary screen 11, it being noted in this connection that the interstices of the screen 11 are smaller than those of the screen 7 in about the proportions shown in Figure 2, so as to lessen the liability of any impurities reaching the conduit 10 and being carried thereby to the carburetor 12 which is preferably of conventional type, or ofany other construction compatible with the purpose of my invention.

At the opposite end of the carburetor 12, with reference to the conduit 10; is a manifold 13 designed to conduct hydro-carbon fuel to the engine, and interposed between the manifold 13 and the adjacent end-of the carburetor 12 is a mounting 14, appropriately connected and equipped with two screens 15 in spaced relation, the said screens 15 being preferably of reticulated material as appears in Figure 3.

Connected at their rear ends with the interior of the container 4 and at their forward endswith the interior of the mounting 14 at points between thescreen 15 are conduits 16, said conduits 16 heingpreferably arranged at opposite sides of the basket screen 7 in the container 4,:1nd being vided at intermediate points in tlieir lengths with casing enlargements 17, Figures land 4, the said enlargement'17 serving to contain non-return valves 18 and-the springs 19 and abutments 20 complementary thereto; and in this connectionitwillbe noted that pro- Q the non-return valves 18 are arranged to seat toward the rear so as to, ermit the passage of saturated air forward y through the conduit 16 while precluding the passage of anything rearwardly through the said conduit 16.

At 19 in Figure 1 I show the internal combustion engine as equipped with a breather device having a foraminous cap 20, and intermediate of the said-breather device 19, and the conduit 8 I interpose a conduit 21, the function of which is to conduct heated air from the crank case of the engine to the conduit 8 at a point adjacent to the mentioned hot plate 3.

In the practical use of my improvement, heated air will be supplied through the conduit 8 to the interior of the container 4 and in passing through said container 4, the said air Will be saturated with moisture and will be cleared of impurities and supplied through the conduit 10 in a clear state to the carburetor 12, and after being commingled with gasoline in the carburetor 12, such air forming with the gasoline a rich fuel mixture, will pass through the screen 15 and the manifold 13 to the engine, and as the engine increases in speed, the suction created will be suflicient to overcome the action of the springs 19 and unseat the valves 18 so that an auxiliar supply of heated and perforated air Wlll be commingled with the fuel mixture at a point intermediate of the carburetor 12 and the engine, with the result that the engine will be enabled to develop greater power, and at the same time the liklihood of carbon gathering in the engine will be reduced to a minimum.

Manifestly inasmuch as my improvement assures the supply of heated and moistened air to the engine together with the fuel, less fuel willibe necessary for the adequate operation of the engine, so that when my improvements are incorporated in an automobile, the automobile may be driven for a,

considerable distance with the consumption of a small portion of gasoline.

It willbeapparent from the foregoing, not'withstandin the capacity of function ascribed to my improvement, the improvement is sim 1e and inexpensive in construction, is relia le in operation, is well adapted to withstand the usage to which automobile appurtenances are ordinarily subjected, and is susceptible-for ready installation in automobiles such as at present in use.

' I have specifically described the construction and relative arrangement of parts embraced in the resent embodiment of my-invention in or er to impart "a full, clear, and

' exact understanding of the said embodiment.

I do not desire however to be understood as limiting myself to the construction and arrangement illustrated'and described, my invention being defined by my present claims within the scope of which modifications may be made without departure from my invention. V

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1.
