CARBURETER.
Specification of Letters Patent. Patent-@d Mmm. 9, 1915.
Application filed February 1, 1913. Serial No. 745,631.
To all whom it may Concern: Y y
Be it known that l, ASHLEY' C. BENNETT, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Y new and useful Improvements in Carbureters, of which the following isa specification.
My inventionrelates to carbureters, and has for its object to provide a carbureter in which the fuel oil will be' delivered into the air passage in extremely thin and widely extended films from a horizontal feed pipe, also to provide means for increasing the velocity of thecair under low speeds where said air passes the fuel delivering members.
The full objects and advantages of my invention will appear in connection with the detailed. description thereof and are par ticularlykpointed out in the claims.
In the drawings, illustratingthe applica tion of my invention in one form. Figure 1 is a section of a portion of a carbureter showing my improvementsconnected theref with. Fig. 2 is a sectional plan view of the delivery pipe for the fuel mixture and the oil spreading means above referred to. Fig. 3 is a plan vi'ew of one of the spreaders employed in connection with my invention. Figs. -l and 5 are enlarged sectional views .showing the spreader members in two different positions. f
By means of a casing 10a fuel oil reservoir or chamber 11 is provided', and separated therefromv Iis another chamber 12 in which said oil is vaporizedrand mixed with air. A horizontal pipe 13 has the interior thereof connected with chamber 11 by means of the duct 14, which is controlled by a` needle valve 15'. Means not shown. of wellknown construction, are provided for keeping the fuel oil within the, reservoir 11 at 'a level approximately that of the top of horizontal feed pipe 13. A port 16 is provided pipe 13 so positioned across the lower end of pipe 19, that both primary and secondary air will enter pipe 19 when flowing in direc' ltions substantially at right angles to pipe 13. Along the upper edge of pipe 13 is formed a series of apertures. 20. Strung upon the feed pipe y13 are a series of distributing members or f insl, each comprising a pair of plates secured together at their bottom edges 22 and 23 and having their circumferential upper edges Q5 normally separated a considerable distance, as'clearly shown in Figs. 1 and 4. The members 21 are held in position on feed pipe 13 at the backs 26 thereof by solder or other fastening means, so that successive apertures Q0 open` the feed pipe 13, the adjacentplates of successive members will contact at the tops of their edges 25, as clearly shown in Figs. 1 and 4. These plates are so constructed as to spring outwardly as above indicated with a very light spring action, so that a comparatively small amount of force is required to close them into the position shown in Fig. 5.
Now, by reference to Fig. 2, it will be :noted that when the members 21 are in normal position with the plates thereof fully expanded so that adjacent plates of successive members contact, a very considerable portion of the area of Vdelivery pipe 19 is closed. When, however, the plates of the succeeding distributing members or fins are closed, as shown in Fig. 5, the area through which air can pass along side of said plates is very largely increased. Now, when the engine is operating at slow speed, and therefore drawing air through the primary port 16 in relatively small proportions, the current of air passing between the adjacent parts of members Q1 will not have sufficient force materially toclose said members. The
aggregate air passage past the edges 25 of members 21. will, therefore, be largely restricted so that the velocity of the air actually passing said edges will be increased, although the amount of air going to the engine cylinder will be the same as would be the case if passage through pipe 19 were not so restricted. The velocity of the air at the point where vaporization takes place has a direct bearing upon the y`rate and eciency of vaporization, the greater the \'elocity the more complete the vaporization. Tt is, therefore, of great advantage to increase the velocity at the vaporization point, and my improvements herein described do this without, of course, in any respect increasing the amount of air flowing to the engine.
is shown in the Figs. l and 4,1 have arranged the members 2l so that the same are of increasingly greater heightfrom the part of the feed pipe positioned toward the fuel admission to the end of said feed pipe. This will have the effect under moderate drafts of causing the fuel oil to feed principally from the edges of the shorter members While as the draft increases the oil will progressively reach the edges of succeeding members until it reaches the highest thereof.
Tt is to be noted that the members 21, positioned asl they are in vertical 'planeslwith `their closed edges. down, infact comprise open topped cups of greater or less extent according to the angle which the edges'22 and 23 make with-one another. Surplus oil kfeeding from the apertures 20 may and will be retained in these cups. As the speed of the engine increases the oil in the cups may be drawn up into vaporizing position as rapidly as the conditions of feedmay require.
T claim:
l. A carbureter comprising a casing forming an air passageway, an oil feed pipe eX- tending horizontally across saidair passageway and provided with openings along one side, means to delii'erfuel oil into the pipe and to the openings, a series of plates or fins secured along said pipe across the air passageway and extending away from said openings, the adjacent members of said plat-es being yieldingly flared so as normally to contact and restrict the area. of the air passages in the pipe, said flared portions being movable by-thecurrent of air passing through the pipe to-vary the amount of said flare and increase the area of the air passageways in proportionvtothe strength of the air current.
2. A earbureter `comprising a pipe for delivering fuel mixture, a feed pipe extending horizontally across said delivery pipe and having apertures along the top thereof, means for delivering fuel oil into said feed pipe and to said apertures, a series of double walled spreader members on said feed pipe, each member having a wall thereof on each side of an aperture, said walls being extended upwardlyy inte the delivery pipe away from the feed pipe, and means for conducting a current of air into said delivery pipe from belovsT the'feed pipe .andlaring members.
3. A carbureter comprising a pipe for de- A livering fuel mixture, afeed pipe extending horizontally across said delivery pipe. and having apertures `along the top thereof, means fordelivering fuel oil into said feed pipe and to said apertures, a series of double walled spreader members on' said feed pipe, each member having a wall thereof on each sidefof an aperture, said walls being extended upwardly into the delivery pipey away y from the feed pipe, and means for conducting a current of "air into said delivery pipe from below the .feed pipe and Haring members, vthe Walls'. of said spreader members progressively increasing in height from the inlet end of the feed pipe.
