UNITED STATES HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed October 23, 1903. Serial No. 178,274.

To all whom, it may concern:

Be it known that I, FRED J. WOQDHEAD, a citizen of the United States, residing at Bakersfleld, in the county of Kern, State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to a burner designed to lurn crude petroleung -oil by the use of steam; and the object thereof is to provide an efficient burner for that purpose in which the sup ly of oil to a certain extent is automatical y regulated by the steam-pressure. I accomplish this object by the burner described herein and illustrated in the accom panying drawings, in which-- Figure 1 is a longitudinal central section of my burner. Figs. 2 and 3 are respectively a plan and a sideelevation f the burner-ti In the drawings, A is the casing of tl fe steam-chamber of my burner, which is made ofordinary pipe of asu'itable size, dc ending upon the capacity of the burner, on tlie front end of which is screwed the burner-tip B.

This burner-tip is divided by partition 0 into two chambers, the lower one of which constitutes the steanr-chamber D and the upper one E constitutes the oil-chamber thereof. Partition C has an internally threaded hole ,0 in the rear portion thereof, into which is screwed the front end of the casing F of the oil-chamber, which extends rearwardly through the steam-chamber and'through T- fitting G, which is screwed upon the rear end 3 5 of the steam-chamber casing. Fitting G has an outlet H, which rovides means for connecting the steam-c amber by apipe (not shown) with a sup ly. On the rear end of the casing of the oi -chamber is screwed a re- 40 duc-er I. which is externally threaded and screws into one of the outlets of the T-fitting G. This reducer extends rearwardlv of the fitting G, and upon it is screwed a T-fitting J,

having outlet K for the reception of an oil-- pipe (not shown) ,to connect it with an oilsupply. In the other outlet of the fitting-J is screwed a hollow cylinder L, the rear end of which is externally threaded for the reception of a gland M, which, with washer N and e packing O, formsa stuffing-box around stem P, which is enlarged within cylinder L, as shoun, and externally threaded to fit the internal threads of the cylinder, and thereby on the rotation of the stem to give it a longitudinal movement in the cylinder. On the rear end of this stem is a hand-wheel R, by means of which the stem may be rotated.

stem passes through the oil-chamber, and its front end terminates in a valve-stopper S, which is adapted to pass into ort T in partition C and regulate the size t ereof and en tirely close the same, if desired. The steam.- chamber is rovided with the semicircular port U and t e oil-chamber is rovided with a semicircular port V directly a ove the steamport and separated therefrom by the end of partition O. Extending through the top of the casing of the oil-chamber is'the regulating-plug W, which passes therethrough in screw-threaded contact therewith and is vertically movable to re ulate the size ofthe oilport and may entire y close the same, if de-.

sired.

laced wit the tip extending into the comustion-chamber of a fire-box (not shown) and is connected up with suitable oil and steam su plies, (not shown,) which are regulated in t. e usual well known manner to supply the oil and steam necessary to produce the desired flame. In the regulation of the oil and steam supplies valve-stopper S is o ened to permit a. portion of the steam mm t e steam-chamber to pass" into the oil-charm. ber, and thereby create a given back pressure on the 'oil flowing into chamber E, which must have suflicient pressure to force it into chamber E against the back pressure caused by the steam passing into chamber E through port T. Thls back ressure is taken into consideration in regu ating the quantities of steam and oil which are admitted into the burner. Thereafter should the steamprefisure vary the quantity of oil and steam passing out of the burner-tip will also vary. If the steam- 'ressure rises owing to its greater force, it chamber E of the burner-tip, and thereby prevent as much Oil entering therein as enter at the time of the regulation, thus reducirxg' the heating powerof the flame produced by the burner. On the other hand, should the pressure of the steam fall below normal the back pressure of the steam lpassing through port T into chamber E wil be less than it was at the time of the regulation, and more In the operation of my burner the same is I create a greater back pressure in oil will flow into chamber E and out of port V 7 steaimplressure of the boiler, it being understood t at the burner is used for producing steamin the boiler which furnishes steam to the burner.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

l. A hydrocarbonburner comprising a steam-chamb er a burner-tip on the outer end thereof, said burner-ti having two chambers therein separated y a partition; ports inthe chambers of said burner-ti one directly above and the other directl be ow the front end of the partition; an o i chamber within said steam chamber and communicating with the upper chamber of the burner-tip; aport in thepartition between the chambers of the burner-tip disposed therein opposite the center of the oil-supply chamber; a valvestopper adapted to control the port in said partltion, said valve-stopper having a stem extending rearwardly through the oil-chamber and having means to give-said stem a longitudinal movement in said chamber.

2. A hydrocarbon-burner comprising an oil and a steam chamber each having an independent outlet-port, said chambers being in communicatidfi'with each other near the outlet-ports; means to control said communi cation, means to create a back pressure by forming passages respectively for the oil and,

atomizmgfluid, said assages having separate outlets, and one of t e Wa ls having an orifice therein leading from the fluid-passage to the oil-passage to communicate t e pressure of the fluid to the oilpassageQwhereby automatically to regulate the oil-discharge, and

means for regulating the area of the oil discharge or outlet.

In witness that I claim the foregoing I have FRED J. WOODHEAD.
