HYDBOCARBON-BUBNER.

To aZZ'wz/m t may concern:

Be it known that I, GARNET W. CoEN, a

citizen of the United States, residing at Venice, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of'which the following is'a specification.

VThis invention relates to improvements in hydrocarbon burners, and it is an object of the invention` to rovide a v-n'ozzleportion having; tangential? arrangedV Aopenings for admitting the hy rocarbon products to a circular chamber adjacent t'o a' discharge out- Intheaccompanying drawing forming a part of this specification, Figure 1 is a 1ongitudinal 'section' of the improved burner,

Fig. 2" is an enlarged transverse sectional viewtaken upon the line 2-.2 of Fig. l1. Fig. 3 is a detail perspective View of the adjustable nozzle controllingmember. y

The details 'and' featuresl ofthe invention 4 will nowbe more dparticularly described, reference being ha tothe said drawing "in which '10 indicates a supply pi 11 acasing and 12 a discharge pipe.v e casing 11 may be of any ordinary or desired construction, having threaded connections from the .outlet pipe 12 valve vstem gland and the inlet p1 e 10.

- e discharge pipe 12 is threaded at its I .outer end and adapted to receive an interthe cap 14 is located a nozzle 16 havingan nally threaded cap 14 having an overhanging inwardly extending annular lape 15 for holding anozzle'in position. ithin annular flan e 17 formed upon the outer end thereof whic is adapted to fit between the flange 15 of the ca and the end of the pipe 12. By screwing t e cap 14 tightly in place upon said ange 17 the nozzle is centrally held in place within the bore of the dischar e 1pc 12 as clearly shown in Fig. 1. The o y portion of the nozzle is of a suciently smaller diameter than the bore of the Specication of Letters Patent. application mea rerruary 5, 191e. serial no. 375,662. o

about the said body portion, for the hydro`V carbon productsto be burned. 'lhe nozzle 16 is also centrally bored and the inner end' of the bore is tapered as shown at 18 so as to tend to convergev and direct the hydrocarbon materials toward the small discharge outlet 419. The/walls of the nozzle are also formed with" inlet passages 2O extending from just inside the flange 17 inwardly. To secure the desired resultv in the atomizing anddischarging of the hydrocarbon products the inlet passages 20 are arranged tangentially with respect to the bore of the nozz'le 16- so'that the'mat'erials forced into the nozzle through said passages will'be given' a whirling tangential direction within' the same and' will be so concentrated upon the tapered end surface of the 'bore and at thc discharge opening 19 -thatra diverging s ralaly t e the end of the burner. The structure will result in a close cone shaped\flame in burning the fuel.

dit

In using the device the hydrocarbon ma- 'terials are usually delivered jin the pipe 10 :to the burner under .pressure and preferably also in a preheated condition, the orclng of the materials, thus further tending to impart a high velocity to the materials passing through the passages 20 to the outlet .chamberthusproducing a thorough twisting or whirling of the hydrocarbon products, which, upon being released through the outlet 19, will be thoroughly disintegrated by centrifugal force and enter the furnace in a completely atomized condition.

The inlet apertures or passa es of the burner may be enlarged or dimlnished in size. `In the device shown the passages-20 are in the form of tangentially arranged slots. Movably mounted within the nozzle 16 is an adjustable member 26 having a cylindrical body portion formed with tangential rojections 27 adapted to extend into the s ots 20. so as to lill the same. The said member 26 is arranged to reciprocate within the bore of the nozzle, the projections 27 being also reciprocated thereby in the slots 20 for increasing or diminishin their o enin The said member 26 is a so provided with a pin projection 28 adapted to pass through the discharge openin Y19 wli'en it The said member 26 is also provi ed with a ar e orifice.

screw threaded bore adapted to engage the threaded end 30 of-a valve stem 31. The other end of the valve stem projects through a'packing. land 32 in the easing 11 and is provided withl la handle 13 by which it may be turned. By turning said stem the member 26 may be moved back and forth in adjusting the size of the passages to vary t the action 'of the burner. By controlling the area of said passages 20, the maintenance of the' maximum velocity in the hydrocarbon material passing through the said passages y 20 under varying initial pressures in the burner up to said passages is obtained and the flow of the hydrocarbon' material to the nozzle chamber,v may beabsolutely controlled at this point without decreasingits velocity through said passa-ges. Thus ifthe flow to the burner is decreased by an suitable means (not shown) the pressure 1nl the discharge pipe 12 would be decreased, resulting in a decreased velocity of the hydrocarbon forced through passages 20, therebyreducing the rotat1ons ofthe material in the noz? What- I claim is:-.. y

1. A hydrocarbon burner'having a nozzle formed with a central chamber and an outlet passage, the walls vof said chamber having tangential slots for: admitting hydrocarbon products. within the nozzle chamber, a member monntedin said nozzle and ided by said slots and adapted to parta y or entirely closethe said slots, and means for operating saidmember-. A

2. A hydrocarbon burner'having a nozzle formed with a central chamber and an outlet passage, the walls of said chamber havingslots extending from said outlet passage to its inner rim, a valve memberto lit sald chamber and provided with guides to'- engage and'register in said slots, and means to actuate the valve member. Y

3. A hydrocarbon burner having a nozzle formed with a central chamber and outlet passage, the walls of said chamber having slots extending from the outlet passage to its inner rim, a `valve Vmember to fit said chamber, a cylindrical needle point adapted to clean said outlet passage, and a screw thread in said valve member adapted to engage a threaded valve stem to actuate the same.

` In witness that I claim the foregoing I have hereunto subscribed my name this 25th day of January, 1912.
