HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed December 16, 1918. Serial No. 267,055.

To all whom it may concern Be it known that we, JAMES TEWSLEY and RALPH D. HORTON, both citizens of the United States, residing in the cities of Long Beach and Los Angeles, respectively, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon Burners, of which the following is aspecification.

Our invention relates more specifically to a hydro-carbon burner construction adapted to be operated by cheap and inexpensive fuels, such as kerosene, distillates, and like hydro-carbon fractions.

An important object is to provide a burner construction in which the flow of gaseous mixture is evenly controlled, and in which the pressure in the burner tubes is efiiciently equalized.

A further object is to provide a construction in which a portion of the generated gaseous mixture for the operation of the burner is stored, the stored portion being.

utilized to prevent any fluctuations in the flow of said mixture in the burner tubes, and also to prevent back firing during its operation.

Other objects and advantages will be ap parent from the following description, the

drawing clearly illustrating the construction:

Figure l is a plan view of our burner with parts broken away to disclose the interior construction.

Fig. 2 is a central longitudinal section taken on line 22 ofFig. 1.

Fig. 3 is a transverse section taken on line 33 of Fig. 1.

Referring more specifically to the drawings our improved burner preferably consists of a manifold gas inlet chamber 5, an equalizing manifold chamber 6, connected to each other by a plurality of burner tubes 7 each provided wlth a plurality of burner slots 8. The size of the burner being such that it will afford easy placement in a stove or range construction of usual form.

The ends of the burner pipes 7 project into the interior of the manifold chambers, as clearly shown in Figs. 1 and 2 of the drawing, so'that the flow of gaseous mixture .into the burner pipes will not be direct,

pipes.

Manifold chamber 5 is provided in its top. wall and at the center thereof with a gas inlet opening 9, communicating with one end of a gas mixing pipe or chamber 10, the free end of said pipe extending toward the center of the burner and terminating between and below the burner pipes 7, the end of the pipe being provided with adamper 11 of usual construction to regulate the admission of air to the mixing chamber. Chamber 10 is provided with an opening 12 into which projects the discharge end of a gas generator 13, the end of said pipe being preferably disposed approximately in the center of the inlet opening of the mixing chamber so that the gas and air will be efliciently mixed before entering the inlet chamber of the burner. By disposing the mixing chamber directly above the gas burner pipes the mixing chamber will be efficiently heated during the operation of the burner and thus highly increase the combustibility of the mixture before it enters the inlet manifold chamber for distribution to the burner tubes.

Generator 13 is of usual construction, and preferably consists of a pipe 14 in which is mounted a plurality of wires '15 which serve to break up the fuel so that the gases will be quickly liberated on a heating of the generator. The outer end of said generator is closed by a cap 16 provided with a centrally disposed gas outlet orifice 17, the

other end of the generator. being connected to a source of fuel supply (notshown) which is preferably fed to said generator under pressure. Secured to or formed integral with the upper. wall of manifold equalizing chamber 6 is a forked support 18 in which rests the outer end of the generator.

Secured to and projecting inwardly from the inner side walll9 of the manifold equala construction that will quickly and efficiently heat the largest range or stove, itonly being necessary when employing a larger number of tubes to increase the area of the manifold gas chambers.

From the above description it is thoughtthat no difliculty will be encountered in un derstanding the operation of our burner. Enough oil is introduced into the firing pan 21 which is then lighted so as to heat the generator 13, oil being admitted to the gen erator from the storage tank by means of a valve (not shown). When the burner begins to generate gas the damper 11 is opened slightly to admit the proper amount of air to the mixing chamber and the gas eous mixture flows forwardly and down-' wardly through the mixing chamber into the manifold inlet chamber 5, the gas in the chamber entering the burner tubes and passing therethrough to the equalizing chamber 6. It has been found in practice that the generator will generate a larger quantity of gas than canbe utilized by the burner tubes and allexcess gaseous mixture that is. not consumed in the passage through the burner tubes is stored in the chamber 6, the gas pressure thus created in the chamber 6 equalizing the pressure in the burner tubes. By this arrangement it will be noted that the size of the flames issuing through the burner slots 8 of the burner tubes will be of the same size throughout their length, the pressure being efficiently equalized. Also it will be noted that by such equalization no fluctuation of the flames issuing from the tubes will occur and all danger of back firing obviated.

It will also be observed from the foregoing that by means of the gas equalizing chamber 6 that greater pressure of the gas will be formed in the outer end of the gas supply pipe 20, the flames issuing from the outer end of said pipe impinging directly against the outer end of the generatortube.

What we claim is:

l. A hydro-carbon burner construction, comprising a gas manifold chamber having a gas inlet opening leading thereto, a gas manifold equalizing chamber, a plurality of anertured burner tubes connecting said naaaaae chambers, a gas mixing chamber connected to the inlet opening of the as manifold chamber, said mixing chamber eing located above and between said burner tubes, whereby the chamber will be maintained in a heated condition during the operation of the burner, said chamber having an air inlet leading thereto, and a gas generator mounted above said burner tubes, the discharge being open to the atmosphere and provided.

with a controlling damper, a generator tube mounted above said burner tubes, the discharge end of said generator terminating within said mixing chamber, and an apertured gas supply pipe having a closed outer end connected to said equalizing chamber, said pipe provided with a firing pan and located beneath said generator tube.

3. A hydro-carbon burner construction, comprising a gas manifold chamber having a gas inlet opening leading thereto, a gas manifold equalizing chamber, a plurality of apertured burner tubes connecting said 0 ambers, a gas mixing chamber connected to the inlet opening of the gas manifold chamber, said mixing chamber being located above and between said burner tubes, said mixing chamber having an air inlet leading thereto, a damper for controlling said air inlet opening, and a gas generator mounted above said burner tubes, the discharge end of said generator terminating within said mixing chamber.

In witness that we claim the foregoing we have hereunto subscribed our names this 26th day of November, 1918.
