To all lwhom t may cmwe'm:

Beit known that I, FERNANDO Co'rERA, a citizen .of the Republic of Cuba and residing at Central Feliz, Province of Matanzas, Republic ofCuba, have invented certain -newf and4 useful Improvements in Double Oil- Burners, of which the following is a `specification.

The invention relates .to oilA burners, and more'particularly to burners which are employed on locomotives.

. "It is an object of theinvention to provide a burner which irrespective of the locomobut with a decreased consumption'of oil and consequently with-a smaller flame 4when thel train'is stopping, thereby Iobviating the necessity of extinguishing and relighting the ame. A further object-of the invention aims at. the provision of double compartments through which-thel'fiiel maybe selectivelyk discharged, vthecompartments being of ,dif-D 1 ferent capacity consonant with the lntention of maintaining a large or small flame. A further object entails the provision of double compartments for the issuance of steam -Whereby a greater or smaller amount" To the accomplishment of the.l objects stated and others that will become apparent as the ,description proceeds, a preferred embodiment of theinvention is disclosedin the accompanying `drawin ,Y describedin the specification, and speci callypointed out '1n the appended claims.

In'said drawing: l ,Figure 1v is alongitudinal sectlon of a burner constructed inaccordance with my invention, the. section being taken .on lme 1-1 of Fig. 2f v, Fig. 2 is an end view of the device from the rightas viewed in Flg. 1; j Fi 3. is a cross-section on the 11ne 3-3 of F1`g."1, and Y Fig. 4 is a horizontal v section of the device through the'fuel containing compartments. Fig. *5 isa horizontal section .of the device throughthe steam, compartments..

Referring tov the various .figures ofthe drawing, 1 generally designates the burner, which comprises four compartments 2, 3, 4, and 5,' respectively,- and separated from one anotherby yvalls.6, 7, 8, and 9. As indicated" more particularly -m-'Fig- 3, the two upper compartments 2`and 3 are vof a larger crossvsection than the' twolower compartments 4 and 5, and again the compartment 2 is larger than the compartment 3, and similarly the compartmentl has a larger cross-section than compartment 5. The upper compart# ments, at the right hand side, as viewed in Figgl, are formed with openings 10 through which'the fuel fed into the upper'compart-v ments' may discharge. In 'order to regulate the discharge openin reciprocating in a groove. The valve is se-v cured to the deviceby a threaded member 12, which extends lthrough aslot 13 inthe valve 11', -wherebyithev position' of the valve with respect to the discharge opening may be va ried to more or less're'strict the discharge opening. The lower compartments 4 and 5 through which steam vis discharged are equipped with openings 14,-and slide valves 15', of a similar construction as the @valves 11, are provided to adjust thedischarge oritice of the lower compartments.

As indicated in Fig. 4, a conduit 16 serves '10` a disk valve 11. 1s secured .togthe end ace -of the device and ,to :supply fuel, such/i as oil or petroleum, to.

lthe compartments 2 and 3 to which end the conduit 16--is formed with a bypass 17, which leads tothe compartment, while the pipe- 16 opens into the compartment 2J Pipes 16 and 17 are equipped with a valve 18 which has .ports 19 and 2O which respectively ex tend in horizontal andverticalhdirection so as to selectively control' the passagejthrou'gh the pipes 1'6'andv 17. As shown in Fig. 4, the --valve 18 permits the passage of the fuel through the pipe 16 into the compartment 2,

' and inlorder to disconnect the -fuel supply t0.

the compartment and to feed the smaller' compartment 3, the valve 18 is rotated about its longitudinal axis until the port 20 as sumes a horizontal position whereas the port 19 extends vertically. The steam icompartments 4 andl 5 are suppliedfwith steam by .means of a pipe v'27 Awhich is provided with a bypass 21,-leading into the compartment 5, while the pipe. 27 opens directly into the 'pipe 23 in 'communication with the compart ment 4. Avalve 24 is interposed in the pipes 21 23, and, is provided wlth spaced i' aperturesv 25 and 26, whereby alternately communication is established between the, pipe 27 and compartmentsff and 5, respectively. To this end, the apertures I and 2Q arey arranged in the same manner as is described, with respect to valve 18.

The operation of the .device is thought to I be obvious: When the .train is in motion and it is desired that the burner have a large flame the valve 18 is arranged as shown 'in Fig. 4, and the valve controlling the supply ofsteam is placed in the same position so that simultaneously fuel may enter the compartment 2 while steam enters the compartment 4. The steam issuin at the outet opening 14 creates an injector action Y in the compartment 2 causing the discharge as has been the of the fuel in the form of a jet, which, when lighted, maintains a large flame. If the train comes to a standstill and it is not desired to maintain such a largeflame', 'it is unnecessary to extinguish the flame entirely practice followed hitherto,

but the valve 18 is rotated until the passage If the lflame is not of a desired size or thethrough the pipe 16'is closed and the passage through the pipe 17 opened, so that fuel discharges through the compartment 3, which is Aof smaller capacity and hence supplies only a' small amount of fuel necessary for the maintenance of a small flame. Together with the 'rotation of the valve 18 the. valve for'the steam supply is actuated so thatsteam is issued through the compartment 5., The flame will then shift transversely and will decrease in size due to the decreased supply of fuel. Attention is called to the'fact that the compartments are of sufficient capacity-to maintain a flame dur-- Iing the interval between the closing of one compartment and the opening of another.

operation of the device not satisfactory, then the valves for the discharge openings of vthe compartments may be adjusted.

While the drawing discloses an embodiment of the invention it is'of course obvious that man alterations and changes may be made wit outdeparting from the spirit of the invention, and it is therefore not my intention of confining myself strictly to the details as shown but to includel all changes, a

modifications, alterations, and substitutions constitutingl departures within the purview of the invention'as indicated by the appended claims.

I claim :v

2. In an oil burner, a plurality of independent compartments of varying capacity for the discharge of fuel, means for creating an injector action in said compartments, and means arranged outside of said fuel com- ',partments for selectively placing said fuel pendent compartments for the discharge of fuel, -a plurality of steam compartments coacting with said fuel compartments for creating an injectorv action therein, andl means extraneous of said fuel compartments for selectively. placing coacting fuel and steam compartments in operation.

5.- In an oil burner, a pluralityof independent compartments having openings for the discharge of fuel, means for creating an injector action in said compartments, means extraneous of said fuel compartments for'V selectively placing said fuelcompartments one `of said fuel compartments in ,f

6. Inan oil burner, a plurality of .independent compartments having openings for thedischarge of fuel, a plurality of compartments having openings for the discharge .of steam coacting with said fuel compartments for creating an injector action'therein, means extraneous of'said fuel compartments'for selectively placing coacting fuel andsteam compartments in operation, and

means for adjusting the openings of said fuel and steam compartments.
