PETROLEUM-BURNER. y

SBECIEIQAEIQ'Aformng part of Letters 'Patent No. 539,375, dated May 14, 1895.

Application filed February 21, 1894. Serial No. 500.993- (NO m0151612) To all whom it may concern:

Be it known that I, LOUIS BAUMGARTNER, a citizen of the Republic of Switzerland, residing at St. Gall,u Switzerland, have invented certain new and useful Improvements in Petroleum-Burners, of which the following is a specification.

The object of my invention is to provide a V to form an opening between their tops, they space between the two sets of pipes gradually increasing toward the bottom. The iamel issues in the shape of a ribbon or band through said opening as a forced flame and during'its passage through the space between the two sets of pipes or channels heats thepipes or channels containing the petroleum, so that the same is vaporized by the time'it reaches the burners.

In the accompanying drawings, Figure l is a side view of my improved petroleum-burner,

parts being broken out and others shown in Fig. 3 is aplan View of the same.

Vertical longitudinal section. Fig. 2 is an end View of the same, parts being broken Yout and others shown in vertical transverse section. Fig. 4 is a vertical transverse sectional view of an annular burner of myimproved construction. Fig.

5 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

The petroleum supply pipe a passes vertically through the bottom of the pan b and a short distance above said pan is connected with the horizontal pipe c, which is arranged diagonally in said pan. The opposite ends of said horizontal pipes c are connected with two groups of pipes d, cl', which are arranged in two planes inclined toward each other, so that a passage fis formed between said two groups of pipes d, d', which passage is gradually decreased in width from the bottom to the top and terminates at the top in the opening e formed between' the upper edges of the two groups of pipes d, d. Each group of pipes cl, d is 'formed of a single pipe bent in zigzag or serpentine shape or is preferably formed of chambers h, h', divided by-transverse partitions g into compartments,- which compartments are connected with each other in the manner shown by the pipes ol, d', whereby an 'approximately serpentine or zigzag channel is formed for the petroleum. The construction with the chambers h, h', and the pipes connecting them is simpler than that in which the channel in formed by bending a pipe in serpentine or zigzag shape. To the end of the channel of each group a piece of tubing t', t" isV attached, which extends downward and horizontally over the bottom of the pan and at its free end and in the vertically central plane of the passage f is provided with a burner-tip lc, 7e projecting upward. The petroleum under pressure passes through the tube a, and is distributed in the two groups of pipes d, d',

before it is consumed at the burner-tip 7c, Za.-

The two iiames issuing under pressure from the burner-tips, pass upwardly through the passage f between the two groups of pipes and unite to form a ribbon-shaped forced flame, which issues from the opening c. In passing through the passagef, the two flames come in contact with the entire inner surface of each group of pipes, whereby said pipes are heated to a high degree and the petroleum passing through the same is vaporized and issues in the form of a vapor-jet from the burner-tips. The screens Z in the pipe-sections i, fi', thoroughly mix the vapors and retain impurities. The outer sides of the two groups of pipes are covered with sheet-metal casing m, which pre vents the flames passing out in any other direction except through the opening e.

ssy

it is evident that the casing m would not be necessary, but when spaces are left between the pipes, a casing must be made around the group of pipes in order to retain the heat.

To start the burner, the two groups of pipes and the petroleum therein must first be heated and this is accomplished by pouring a combustible fluid into the panpb and igniting the same. Openings n arev provided in the bot- IOO tom of the pan` to permit currents of air required for combustion to pass through them to the flames. Necks project upwardly from the edges of said openings to prevent the combustible fluid flowing off through said openings.

In place of arranging the two groups of pipes in two planes inclined toward eachother, they may be shaped to form two concentric cones as shown in Figs. 4 and 5. Thereby an annular opening is formed through which the annular llame can issue.

, In place of arrangingthe pipes in the form of a cone, they can be arranged to form 'cylindrical or pyramid-shaped bodies lor bodies forth.

of an oblong shape.

Having thus described my invention, I claim as new `and desire to secure by Letters Patentl. A petroleum burner having va burner-tip and a pipe for conducting the petroleum to said tip, said pipe forming an upwardly-extending and inwardly-inclined serpentine channel for the petroleum, and the said pipe being located above the burner-tip, whereby the petroleum passing through the channel formed is vaporized, substantially as set forth.

2. A petroleum burner constructed with two burner-tips and two `groups of pipes forming serpentine channels for the petroleum passing to the burner-tips, which two groups `of pipes are arranged in two inclined planes to form between their top edges an opening from which the inner part of the'iame issues, the tips being located below the groups of pipes to vaporiie the petroleum passing through them, substantially `as set forth.

3. In a petroleum burner, the combination with two groups of serpentine pipes or channels arranged at au inclination in ditterent planes, a burner-tip connected with one end of each group of pipes and a supply-pipe connected with the other ends, said burner-tips being arranged at opposite ends of the burner so that the oil travels in opposite directions in the two groups of pipes, the middle line of .the groups of pipes being located above the burner-tips and the upper edges of the groups forming an opening through which the inner part of the tlame issues, substantially as set 4. In a petroleum burner, the combination, with two `groups of pipes arranged atan inclination in dierent` planes and between the upper edges of which an opening is formed each group being composed of a top and bottom chamber divided by partitions into compartments and united by pipes, a burner-tip at one end of each group below the pipes, a petroleum supply-pipe connected with the opposite end ot each group and `a casing or mantle `around the group of pipes, substantially as set forth.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 2d day of February, 189i.

LOUIS BAUMGARTNER.
