THOMASiF. KENT, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO EDWARD L.
ADREON, JR., OF ST. LOUIS, MISSOURI. i
BURNER.
To all lwhom it may concern.'
Be it known that I, THOMAS F. KENT, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Burners,` of which the following is a full, clear, and exact description, such as will enable others skilled in the art to whichit appertains to make and use the same.
This invention relates to burners of the type in which fuel, either in a liquid or gaseous form, is mixed with another medium such, for example, as air or steam, to produce aflame.
One object of the invention is to provide a burner of simple construction that can be manufactured cheaply and which is so designed that some of the air or other substance which supports combustion can be admitted to the fuel chamber so as to induce a free flow of the fuel through the fuel duct in the nozzle.
Another object is to provide a one-piece burner that cannot get out of o-rder and which is so designed thatthe fuel will be thoroughly split up and divided into minute particles.
Figure 1 is a vert-ical sectional view of a burner constructed in accordance with my invention; Fig. 2 is a top plan view of the burner shown in Fig. l; Fig. 3 is a horis zontal sectional view taken on approximately the line 3-3 of Fig. l; Fig. 4 is a vertical sectional view illustrating a slight modification of my invention; Fig. 5 is a top plan view partly in horizontal section of the burner shown in Fig'. 4L; and Fig. G is a vertical sectional view of still another form of my invention.
Referring to Fig. 1 of the drawings which illustrates the preferred form of my invention, A designates a hollow member that forms a chamber 1 which receives the substance or medium that is mixed with the'fuel to support combustion, said member having a laterally projecting internal screw-thread ed boss 2 which receives a supply pipe 3 that communicates with the chamber 1.
My improved burner can be used with fuel that is in either a liquid or gaseous state, and various fluids such, for example, as steam or air can be used to support combustion or atomize the fuel.
A hollow device B which is arranged inside of the chamber 1 forms a fuel chamber Specification of Letters Patent.
Application filed April 15, 1911.

serial No. 621,295.
4to which fuel is supplied by means of a pipe 5 that is tapped into a boss 6 on one side of the member A that forms a continuation of the hollow device B. The device B is cast integral with the member A and one end wall of the member A isV provided with an integral nozzle 7 which is tapered or approximately conical-shape, as shown in Fig. 1. Inclined ports or openings 8 are formed in said end wall adjacent the base or inner end of the nozzle 7 so as to cause jets of air to travel longitudinally of the nozzle in close proximity to the outer surface of same and converge at a point beyond the end of the nozzle and in direct alinement with theV fuel port or duct 9 that is formed in the nozzle, these ports or openings 8 being inclined at approximately the same angle as the outer surface of the nozzle 7. The velocity of the jets of air that emerge from the ports 8 and travel. longitudinally of the nozzle to the common meeting point beyond the end of the nozzle, creates a suction or vacuum which I causes the fuel to be drawn out of the fuel duct 9, and when this stream of fuel comes into contact with said jets of air the fuel. is split up or divided into Very minute particles and is spread out or thrown outwardly owing to the fact that the combined pressure of all of t-he air jets isk concentrated at one point where said jets meet. It will thus be seen that my improved burner causes the fuel to be thoroughly split up or separated and combined with the medium that is mixed with same to produce combustion; and furthermore, said burner produces intense heat because the fuel and air or other medium are mixed at a common point at which the pressure of all of the jets of air is concentrated. Furthermore, by increasing the pressure of the air or other medium that travels through the ports 8 the size of the flame will be increased, owing to the Vfact that the air spreads outwardly more when it is under greater pressure.
Another desirable feature of my burner is that the fuel and the medium that supplies combustion or atomizes the fuel, are mixed at a point beyond the nozzle or end of the burner instead of on the inside of the burner. And still another desirable feature of my burner is that there is no possibility of the fuel supply beinginterrupted or cut oif by back pressure produced by abnormal pressure of the air because the air is discast integral with the hollow member A that forms the air chamber as previously described, and, if desired, said member A can be so formed that the interior of same can be cleaned out, the burner herein shown having a clean-out opening in one of the end walls of the member A which is normally closed bythe removable cap or plug 11. Y l
VInstead of providing the end wall of the member B with inclined ports 8 through which the jets of air escape from the air l chamber, said end wall can be provided with a number ofrelatively large openings or ports 8a, as shown in Figs. 4 and 5, andanadjustable member C can be provided for controlling the supply of air that travels longitudinally of the nozzle 7 and converges at a point beyond the end of said nozzle. The air-controlling member shown in Figs.
-4 and 5 consists of a sleeve adjustably mounted on one end of the member A and provided with a wall 12 having a beveled opening 13 through which the tapered nozzle`7a projects. By moving the sleeve C in one direction the width of the slot between the edge of the beveled opening 13 and the outer face of t-he tapered nozzle 7a will be reduced and thus cut down the supply of air that travels longitudinally of the nozzle, and by moving said sleeve in the opposite direction the width of the slot will be ,increased and thus increase the supply of air. The burner illustrated in Figs. 4 and 5 operates in the same manner and produces the same results as the burner shown in Fig. 1 because the ring-shaped current of air that travels longitudinally of the nozzle converges at a common point beyond the end of the nozzle and thus sucks the fuel out of the fuel duct 9 and splits it up into very minute particles which are thoroughly mixed with and distributed through the spray ofA air that spreads out Copies of this patent may be obtained for Alaterally Vfrom the point at which the air and fuel miX. If desired, a shield D or protecting` wall can be'employed for protecting the flame when the burner is used out-of-doors but this shield is not essential Vand does not change or affect the operation of the burner, the shield D herein shown being taperedslightly and carried by the adjustable sleeve C that controls the supply of air.
In Fig. 6 I have shown a burner in which` the supply of air can be regulated but said burner is constructed in a slightly different manner from the one shown in Figs. 4 and 5. In the form of my invention illustrated in Fig. 6 the fuel member B which carries the tapered or conical-shaped nozzle 7b is adjustably mounted in the member A that forms the air chamber, and the' nozzle 7b projects outwardly through a beveled hole 13a in one of the end walls of the member A. By bodily moving the member B'r lonf gitudinally of the member A', the width of the slot through which the air escapes from the air chamber can be varied and thus increase or diminish the supply of air.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l
A burner consisting of a hollow member that forms a pressure chamber which is adapted to hold a fluid that is to be mixed with the fuel, aA fuel-supplying device ar-V ranged inside of said member and formed integral with same, a lateral hollow boss on said member communicating with said fuelsupplying device, an integral tapered nozzle on the end wall of said member providedV THOMAS F. KENT.
