HYDRQCABBCN-BURNER.

Specification of Letters Patent.

To all 'whom it 'may concern:

Be it known that I, Moses H. DUNN, a citizen of the United States, residing at Los Angeles, county ofLos Angeles, and State of California, have'vinvented certain new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification.

This invention relates tov hydrocarbon burners.y

, My invention has forits objectsl the provision of a' simple, durable, andhighly eftlcient burner adapted to use crudeoil in connection with steam or air under pressure and which, due to its improved constructlon and `the relationship of the nozzles of its steam or air and oil pipes, spra s the oil to a relatively great dlstance, -a Ording a superior delivery and combustion without the accumulation of any hydrocarbon deposit at the `nozzle or mouth and thereby overcomes a defect inc1dent to burners of this general tice, that theimproved construction at the mouth or nozzle of the inner tube, by its cooperation with the outer tube,while chok ing the air under pressureor steam, permits the liberation. of the steam or airin such manner that'it commingles with the oil and forms' the latter into a spray which is pro jected with,considerable force for a relatively great distance, and4 the burner is thcrebyadapted for use ,in connection with steam boilers and insures the flame reaching well up around 4the sides of the boiler and .evenly through the tubes or over the sur-- face and wallsof the furnace, as the case may be. At the same time, the nozzle does not clg with hydrocarbon deposit. A

An embodiment of the invention adapted to carry out the foregoing objects and results is set forth fully hereinafter, but it is to be understood that I do not limitmysclr to the'exact sizes and proportions ofthe parts nor tothe details of construction except where specified in the claims.

In the accompanying drawings: Figure 1 1s a side elevation; Fig. 2, a longitudinal section; Fig. 3, a cross section on line 3 3, Flg. 2; and Fig. 4, a detail perspective of 'the nozzle et the end of the inner tube.

The air or steam tube 1 is 'provided with a Vnozzle or mouth 2 of elongated form which 1s longer than the internal diameter f the sa1d tube The tube 1 is screwed at 3 into a union 4 which is adapted to receive air or Patented July 7, `1914..

steam at 5 from any suitable pipe. The inner or oil tube (i'has screw threads 7 engaged w1t-h the nut 8, the latter being screwed into the union at 9. By this means theoll tube is subject toadjustment longi-4 tudinally, to a limited extent, in relation to the tube 1. The tube 6 is of somewhat smaller diameter externally than the internal diameter of the tube 1, whereby the air or steam may pass along the tubes and between them on its way to the nozzle or mouth 2. The end of the tube 6 is flared at 10 1n general conical or beveled form up to the narrow flattened and circular part -11 which fits the interior of the tube 1 at a distance inwardly from the nozzle 2. Usually in a small size of the burner where the internal diameter of the tube 1 is, say, threequarters of an inch and the internal diameter of the tube 6 is one-half of an inch, length of tube l would be about twelve to fifteen inches and that of tube 6 approximately nine to twelve inches. burner, the distance between the nozzle 2 and nozzle of tube 6 may be as great as nine inches, more4 or less as, for instance, where the internal diameter of the tube 1 is one andv oneuarter inches and the internal diameter o the tube 6 is one-half inch, the length of the tube 1 may be thirty inches and that of tube 6 about twenty-one to twenty-two inches. I have found, by .experiment, that these distances have a relationship tothe eiciency of the burner, but

4in stating them, I do not limit myself, ex-

cept'where specified in the claims. Between the abovelimits, the longer the outer tube 1,

the farther the nozzle end of inner tube 6 i should be from-the nozzle 2 of outer tube, in

order that the oil and steamy may become thoroughly 'united so that on leaving the burner all will be consumed and transformed into heat. Grignating in the outer surface of the tube 6, grooves 12 extend longitudinally of the .tube through the beveled or conical part 10 and the) part 11, as at 13,

' an inner tubeof smaller external diameter' widening until they reach their greatest theform of a spray which is widely spread and projected with considerable velocit-y.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent, is:- A

1. ln an oil burner, the combination With an outer tube having a nozzle orjmouth, yof

vthan the interior of -the outer tube and provided with a coned or -iared end whose largest part or base subetantially'its the inn terior of the outer tube, said dared end being provided with external grooves which are Widest zit-their discharge end and taper or decrease in size inwardly until they submoese@ stanti'a-lly merge into the outer surface of the inner tube', said coned orxflared end being located inwardlyin relation to the nozzle. of theouter tube.

2. lin an oil burner, the combination with an 'outer tube havung a nozzle or mouth, of

an inner tubeof smaller external diameter than the interior of the 'outer 'tube and provided With a coned or dared end having a cylindrical pari-at its largest diameter substantiallyfitting the interior of .Ithe outer tube, `said dared end being provlded with external grooves 'which are Widest at their discharge end and taper or decrease in size until they substantially. merge into the outer surface of the inner tube, 4the end of the inner tube having an internal ,bevel which pirovides a relatively sharp eircuiair end thereon.
