FUEL-CEABiGlE-DILUTING DEVICE.

Application filed December 16, 1924. Serial lilo. 756,319.

This invention relates to an improved fuel charge diluting device for internal combos-- eilicioncy of the engine, but also to reduce.

the formation of carbon in the engine cylinders.

v The Invention seeks, as a further ob ect, to

provide a device which may be readily ii -4 stalled and'which will be controlled in uru-,

son with the throttle valve of the engine carburetor; H

And the invention seeks, as a still further ohject, to provide a'device constructed in such manner as to facilitate the manufacture of the device.

Other and incidental objects will appear hereinafter.

in the accompanying drawings:

Figure l is a plan view showing my i1nproved device installed between a conve t? tional carburetor and engine intake inanifold.

Figure 2 is a vertical sectional view taken medially through the device. 3 Figure 3 is a transverse sectional view on the line 3-3 oi Figure 2, looking in the direction indicated by the arrows.-

Figure i is a fragmentary horizontal seotiona view on the line 5% of Figure 2, looking in the direction indicated by the arrows.

lln carrying the invention into efl'echd employ a body block which, as shown in Figure l of the drawings, is shaped to fit between the confronting flanges 11 and 12 of an engine intake manifold 13 and carburetor i l. Suitable gaskets 15 are disposed be tween the parts and extending through said flanges and through the block are bolts 16 clamping the block in position. The mani told 13 and carburetor 1d are, of course, conventionally illustrated. However, it is desired to note that the carburetor includes the usual throttle valve having a 5mm 17., to which is fixed a lever 18, and. engaged with the free end of said lever is the customary control. rod 1%, the adjacent end fitting in said opening 7 of which is bentdownwardly, in the usual manner to' form a' terminal extending through the lever. 1

Formed in the block-10 is a central opening 20, stepped adjacent the rear side of t the block to define an inwardly directed an-Q nular flange 21, and snugly but removably said flange terminating flush with the rear face of the block, At the lower side of the opening 20 is, as particularly shown in Figure 2, a transverse locking rib 23 while the core-1s formed with a groove accoinrnodatlng said rib sothat the core is thus locked against rotation. At is upper side, the core is cut awaythroughout substantially half the circumference thereof to produce a radial flange 24 snugly fitting in position, a semi-circular passage 25 is defined between said flange and the flange 21 of the block hitegrally formed on the core is a spider comprising a air of forwardly converging arms 26 which, at their rear' is a core or ring 22 re duce'd near its rear edge to snugly fit through 7o 7 the opening 20 oi the block 10 so that when the core is in ends, are united'with the core at its inner circumference while, at their forward endsp said arms are merged and continued to form a forwardly directed cylindrical nozzle 27. Formed through the arms to communicate with the ends of the passage 25 are passages 28 opening into said nozzle, Mounted upon the spider is a disc-shaped, spreader 29 hav ing a stem 39 extending through the noz-v ale and screwed through the crotch between the arms 26. lhe spreader is provided with a cupped rear face for deflecting radially in a thin sheet, the vapors emerging from the nozzle and, as will be perceived, the spreader may be rotatably adjusted for p0- sitioning the spreader with respectto the forward end ol the nozzle.

Formed through the block 10 above the openin 20 therein and at a right angle to the axis 0' said. opening, is a passage 31 con nected medially with the passage 25 by a port 32 and opening into the passage 31 near one end thereof is a downwardly extending passage 33, the lower end of which is open to the atmosphere. Detachably connected with the adjacent end of the passage 31 is a moisture supply pipe 3d leading from the radiawith the radiator in'any approved manner and adjustably but preferably communicates neck of the radiator so that steam will be supplied through said pipe to the passage 31. Slidable in the outer end of said passage is a piston valve 35 having a stem 36 fixed to said stem is an angle plate 37 secured by nuts 38 screwed on the stem. The plate 37 is disposed to overhang the block 10, and pivotally connected to the free end of said plate is a link 39, the free end of which is apertured to receive the terminal at the adjacent end of the control rod 18.

' ing a steam will then As Wlll now be'seen in view of the foregoing description, to the position shown in Figure 1, for closing the throttle valve of the carburetor 14, the valve will be shifted across the port 32 for closing said port. On the contrary, when the lever is swungfor opening the throttle valve, the valve 35 will, as the openmovement of the throttle valve proceeds, be gradually shifted outwardly to uncover the port 32, so that air and steam will be drawn in through the passage 33 and pipe 34 into the passage 31 to become mingled in the latter passage. The mingled air and be drawn through the port 32 and through the passages 25 and 28 as well as through the nozzle 27 to strike the spreader 29 and be spread out in a thin sheet thereby. Coincidently, the. carburetted fuel from the carburetor will be drawn through the central opening of the core 22 about the nozzle andspreader so that the mingled fresh air and steam will be injected into the carburetted fuel to form a diluted fuel mixture for delivery through the manifold 13 to the engine.

Having thus described the invention, what I claim is:

1. A diluting device including a body block having an inlet passage communicating with the atmosphere, and a core carried by the block and provided with an opening for the fiow of carburetted fuel as well as with a nozzle disposed opposite said opening and connected with said inlet passage.

2. A diluting device including a body block having an inlet passage communicating with the atmosphere, a core carriedby the block and provided with an opening for the flow of carburetted fuel as well .as with a nozzle disposedopposite said opening and connected with said inlet passage, and a with the filler when the lever 18 is swung core being rovided with a spreader disposedat the discharge end of v the nozzle.

3. A diluting device including a body block having an inlet passa e communicating with the atmosphere, anrf a separate core carried by the body opening for the flow of carburetted fuel, the core having a ating with the block to define a passage connecting the nozzle with said inlet passage.

4. A diluting device including a body block having an inlet passage communicating with the atmosphere, a separate ringshaped core carried by the body and provided with a spider terminating in a discharge nozzle, the spider being formed with a passage leading'to said nozzle, and a core cooperating with the block to define a passage connecting said passage of the spider with said inlet passage. g

5. A. diluting device including. a body block having an inlet passage communicating with the atmosphere, a core carried by the body and provided with a spider terdischarge nozzle and cooper-- minating in a discharge nozzle, the spider being formed with a passage leading to said nozzle and the core cooperating with the block to define a passage connecting said passage of the spider with said inlet passage, and a spreader disposed opposite the nozzle and having a stem extending through the nozzle andadjustable upon the spider.

6. A diluting device including, a body block having an inlet passage communicating with the atmosphere and provided with an opening as well as ing into said opening, and a core having integral forwardly converging spider arms merging at their forward ends and provided with a discharge nozzle, one of said arms being formed with a passage leading to the nozzle andv the core being cut away to fit through said flange as well as to produce a flange cooperating with the block and with said first mentioned flange to define a passage connecting the passage. of said arm with said inlet passage.

7 A diluting device including a body block having a core provided with an openingfor the passage of carbureted fuel, the portion extending forwardly from the core and formed with-a passage communicating with the atmosphere through the block and terminating in a nozzle disposed opposite said opening at .the forward end of said portion.

In testimony whereof I afiix my signature.
