WILLIAM A. HEIDE, OF DETROIT, MICHIGAN.

- Application filed October 1, 1919. Serial 170. 327,777.
To. all whom it may concem: v
' Be it known that I, WILLIAM A. Huron, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Carburetor (Case A), of which the following is a'specification'.
This invention relates to carburetors for utilizing both gasoline and kerosene, it being designed primarily to use the gasoline for priming purposes and for driving the engine until well heated, after which the kerosene can be directed into and mixed by the A still further object is to provide a structure -of this character which is compact,
durable and eflicient and can be controlled readily. With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of'construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and ar rangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention asset forth in the appended. claim.
In the accompanying drawings the pre ferred form of the invention has been shown.
Figure 1 .is a vertical section through a carburetor for use in connection with a vertical intake manifold.
Figure 2, is a horizontal sectiontherethrough.
Figure 3 is, a vertical sectionthrough a modified form of carburetor of smaller capacity and designed for use in connection with ahorizontal intake manifold.
Figure 4 is asection on line 4-4, Figure3.
Figure 5' is a detail view of a portion of a modified form of valve.
Figure 6 is a similarview of another modified form. a
. Figure 7 is a perspective view of the '3' project. The end 10 block used in the conduit and which is shown in section in Figure 1.
Figure 8 is a section on line 8-8 Figure 3.
Referring to the figures by characters of reference, 1 and 2 designate separate bowls or receptaclesvfor holding gasoline and kerosene respectively and'extending over and secured to each of these bowls is a block 3 each having an angular transversely extending boss 3 extending from the inner side thereof, the blocks being oppositely arranged and the bosses 3 being spaced apart to form therebetween a slot 4. A coupling member 7 is formed at one end of a conduit 8 and provided in. opposed walls of the conduit are openings 5 into which the bosses of the conduit constitutes an air intake. A, block 9 is ,seated against the bottom faces of the bosses 3 and within the conduit 8 and has spaced passages extending therethrough as shown particularly in Figure 9. Side wings 9 extend upwardly from the block 9 and project between the sides of thebosses 3', as shown in Figure 2. For the purpose of holding c the blocks 3, conduit 8 and block 9 assembled, screws, 6 are extended into the blocks 3 from the outer sides thereof and through the walls of the conduit 8 into engagement with the block 9. See Figure 1.
Formed within the block 3 at one side of the slot 4 are separated pockets 11, 12
and 13 and another pocket '14; is formed in' the block at the other side of the slot 4 and directly opposite and in the same plane with the pocket12. Air ports 15 open into the pockets 11, 12 and 13 and each is intersected by a downwardly extending passage or port-16.- Tubes 17 extend downwardlyfrom these passages 16 .and into the lower portion of the kerosene bowl 2 while needle valves 18 are mounted in the passages 16 for controlling the flow of fuel and air into the sucti n is set up by intake manifold. I
An air port 19 opens into the pocket 14 and has a passage 20 extending downwardly therefrom and opening into a tube 21 supthe engine through the ported within the gasoline bowl 1. A needle 24 opening into the slot 4 at points above the pockets and being intersected by a rotary valve 25 adapted to be operated in any suitable manner and normally closed. By providing a series of passages 24 the fuel is delivered in several jets at different points adjacent pocket 14 so that the fuel is thus more thoroughly mixed with the air than would be possible should the same amount of fuel be delivered in a single jet. Floats 26 are mounted in the respective bowls 1 and 2 and are adapted to control the flow of fuelinto the bowls from feed pipes, not shown.
A throttle valve in the form of a fiat plate 27 is slidably mounted in the blocks 3 and upon the upper surfaces of the pockets and this plate has separate tongues 28, 29 and 30 which slide within the pockets l1, l2 and 13 respectively and are provided with'recesses in their free ends.- As shown in Figure 2 each recess has its side edges stepped inwardly,'as indicated at 31 or if preferred, and as shown respectively in Figures 7 and 8 the recesses are V-shaped, as at 32 or rounded as at 33. The free end of the tongue 29 is preferably in transverse alignment with the inner end of the recess in the tongue 30' and the end of the tongue 30 is preferably in transverse alignment with the innerend of the recess in the tongue 28. An opening 34 is formed in the plate 27 directly opposite the tongue 29 and extends throughout the width of the pocket '14. The sides of this opening are stepped as shown and converge toward the free end of the tongue 29. A cut off rib 35 is arranged transversely upon the bottom face of the plate 27, this rib being located between the opening 34 and the end recess in tongue 29.
When the engine is started it will create a suction through the carburetor. By shifting the plate or throttle valve 27 to the right in Figure 1 the opening 34 will be brought gradually into position within the slot4 and the rib 35 will be moved into the pocket 12 so as to close communication between passage 15 and slot 4. Thus the suction will'draw a portion of the gasoline upwardly from the bowl 1 and through the opening 34 into the-intake manifold, said gasoline bein mixed'with air in the pocket 14 and also in the slot 4. The amount of gasoline supplied to the engine will depend upon the width of the opening 34 exposed in the slot 4. After the engine hasbeen driven for a while with gasoline as a-fuel and has become thoroughly heated, the throttle is moved in the opposite direction so as first to bring the. inner end of the 4 pockets.
recess in tongue 29 into register with the slot 4. Kerosene will thus be sucked to the engine by way of pocket 12 and the amount of fuel thus supplied will depend upon the position of the tongue relative to the slot 4. After the end recess in tongue 29 has been moved across the slot 4 the end recess in tongue 30 will move to active position and this will be followed by the end recess in tongue 28. Thus the amount of fuel fed buretor should be constructed as shown in Figures 3 and 4 wherein the bowls have been indicated at 36 and 37 and the kerosene pockets 38 and 39 are located one above the other. Furthermore the plate forming the throttle valve is arranged verti'cally, as shown at 40. In this structure the carburetor is shown of less capacity than in the form shown in Figures 1 and 2, there being only two pockets 38 and 39 for the kerpsene and, consequently, only two recessed tongues 41 and 42 working in the In all other respects the structure is substantially like that hereinbefore described, and includes tubes 17 extending from the ports 15 into the bowl 37 and a tube 21 extending into the bowl 36. Valves 18 and 22 control the flow to these tubes 17' and 21 respectively.
What is claimed is:
In a carburetor the combination with separate fuel bowls and blocks each having a pocket communicating with one of the bowls, of means for admitting air to the pockets, a conduit between the blocks having a slot in its walls, afuel controlling throttle movable transversely of the slot and within the pockets, there being spaced fuel openings in the throttle either one of which is movable into register with the slot, and a rib carried by the throttle and movable therewith into either of the pockets to close communication between said pocket and the slot.
In testimony that I claim the foregoing as my own, I ture.
