VAPOR-BU RN ER.

l SPECIFICATION forming part of Letters Patent No. 736,013, dated August 11, 1903. Application tiled May19, 1902. Serial No. 108,008. (No model To @ZZ whom t may concern:`

Be it known that I, EDWARD WALTER PRITCHARD,a resident of Dallas, in the cou nty of Dallas and `State of Texas, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert'ains ro to make and use the same.

My invention relates to an improvement in vapor-burners, the object of the invention being to provide an improved burner in which steam will be utilized to heat the oil, mix

with the vapor, and be burned therewith.

With this object in View the invention consists in certain novel features of construction and combinations and arrangements of parts, as Will be more fully hereinafter described,

zo and pointed out in the claims.

In the accompanyingdrawings, Figure lis a'view in section illustrating my improvements. Fig. 2 is a plan view, and Figs. 3 and 4 views of details of construction.

l represents a burner-tube having screwed onto one end a curved burner 2, closed by a cap 3 and slit near the cap, as shown at 4, through which the combustible mixture is fed and burned. On the opposite end of this tube 3o l an enlarged steam-chamber 5 is screwed or otherwise secured and is provided with a teat 6, into which a steam-supply pipe 7 is screwed and adapted to supply steam to the chamber 5 and tube l. An openingis provided in the rear wall of chamber 5 to receive a tightlytting coupling 8, comprising two diverging cones with an enlarged angular center 8a to receive a wrench and permit rotation thereof. This coupling 3 is screwed into chamber 5 and 4o connects a T-coupling 9 with a long nozzle 10, projecting into tube 1, and with said T- coupling 9 an oil-supply pipe 9a is connected, as shown. On the inner end of nozzle 10 an elongated tubular cap 11 is mounted and slit at its closed end for the escape of vapor into tube 1. This cap Il is mounted to slide'longitudinally on nozzle l0 to lengthen or shorten the same and compel the oil to pass through a longer or shorter heating zone before es- 5o cape. This adjustment is accomplished by means of a long screw-threaded rod 12, connected at its inner end to a cross-pin 13 in cap 11 and projects at its other end through packing-nuts 14, 'closing one end ofrT-coupling 9, and a set-nut 15-is located on the protruding end of rod 12 to move the latter longitudinally when nut l5 is turned, and thereby adjust the cap longitudinally to lengthen o r shorten the nozzle.

In operation oil is fed through nozzle 10, which latter is heated by the supply of steam surrounding the same. The oil is vaporized and escapes through the slit in cap l1 and is mixed with the steam and the mixture burned at the slit 4 in burner 3.

ments the steam not only serves as a part of the combustible mixture, but also as a heating medium to vaporize the oil, and I produce a burner which is extremely simple in construction, cheap to manufacture, and highly efficient as a heater. Y

A great many changes might be made inv the general form and arrangement of parts described without departingfrom .my invention, and hence I do not limit myselfto the precise construction set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

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

l. The combination with a main supplypipe provided with a burner at one end and a steam-supply connection at its other end, of an oil-supply extending into and only part way through the main supply-pipe and thereby forming an oil-and-steam-co-mmingling chamber in the outer end thereof, a sliding sleeve encircling the discharge end of the oil-supply pipe, a rod extending through the loil-supply pipe and secured to the sliding sleeve, and means for adjusting the rod and sliding sleeve longitudinally andl thereby varying the length ofthe oil-vaporizing chaml ber, substantially as set forth.

2. The combination with a burner-tube and means for admitting steam thereto, an oilsupply pipe, a T-coupling thereon, an oil-supply nozzle projecting into the tube and a coupling connecting the T-coupling and nozzle, of an elongated tubular cap closing the inner end of the nozzle and slit in its closed '65 It will thus be seen that with my improvey IOO end, a screw-threaded rod extending through specification in the presence of two subscribthe nozzle and couplings and through packing witnesses.
