HYDROCARBON-BYU RN ER.

SPECIFICATION forming part of Letters Patent N o. 659,344, dated October 9, 1900. Application filed May 23,1900. Serial No. 177,635. (No model.)

To all whom, t may concern,.-

' Be it known that I, WILLIAM S. HAWORTH, a citizen of the United States, residing at Detroit,l county of lWayne, State of Michigan, have invented a certain new and useful Improvement in Hydrocarbon-Burners; and I 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 pertains to make and use the same, refer-V ence being had to the accompanying drawings, which form a part of this specication.

My invention relates to vapor-lamps in -Which incandescent mantels are employed and gas is generated from a liquid hydrocarbon; and it consists in certain novel arrangements and combinations hereinafter described and claimed.

In the drawings, Figure l is a vertical central sectional view of a lamp and its various parts,showing the arrangement and construction. Fig. 2 is a cross-sectional view4 on line .fr m.

A is the pipe, leading to the source of supply controlled by a stop-cock B.

O is the framework, carrying the lamp and attachments, including the chimney. The framework O is perforated,so as to allow air to pass into the flame-space and surround the base of the generator D, which is preferably cast in one piece and having bored passages d d, which at d communicate with a source of supply. These passages are connected at d2 with a stand-pipe D' and continued therein d2 cl3 in a looped form. The passages can be formed as already stated,by boring at different angles into the casting of the generator and then plugging, as shown at d4 d4, and leaving the interior passages connected as stated. An oriiice E allows the vapor from the burning liuid to escape into the rectangle formed by the framework of the generator D. This constitutes a portion of the mixer, the framework being inclosed in a tube F, forming a mixer, which is open at the bottom or has openings and which surrounds the mixed vapors formed in the mixer. The casing F extends above the rectangular portion of the generator and is closed off by a gauze G. Surrounding the upper portion of the mixer and properly sup- 1 l ported is a mantel II,which is held by a gallows-frame Jin the ordinary manner.

A clearing-out valve L is used in connection with the passage E,whicl1 is more liable to be choked than any other point. It also serves the useful purpose in varying the opening in order to increase and decrease the velocity of the gaseous flow through it.

f `A circumferential pocket M is attached to the bottom underneath the needle-valve L and which in practice is filled with combustible which-is allowed to bring the heat to the generator D. About this there is nothing especially new.

The mode of operation of this device is readily understood; The parts being propverly connected with a source of supply of hydrocarbon, a small quantity of wood-alcohol is placed in the cupMand ignited. Its combustion heats up the mixer-generator D and the hydrocarbon is turned on by the valve B. The needle-valve L being open'and the passage-way E clear, the hydrocarbon entering through the inlet d' passes up the right-hand passage d through the horizontal passage d2, 'up the right-hand passage d3, down the lefthand passage d5, through the left-hand horizontal passage d2, through the left-hand passage d, thence to the orifice E, it being vaporized by the heat of the generator before it reaches E. Rising from E the vapor passes up around the generator inside the tube F, where it is mixed with air passing in at the bottom of F. This mixture of air and vapor rises through the gauze G and is ignited, burning inside of the mantel H, creating therein an intense white light. At the same time it heats the upper portion D of the generator-,through which all of the hydrocarbon -is compelled to pass, making it very hot and completely vaporizing the hydrocarbon. This heat is communicated also to the lower portion D of the generator by conduction, so that the horizontal passages d2 d2 afford considerable space in which to vaporize the hydrocarbon.

I am aware that spiral tubes have been used in flames as generators, but the trouble has Ibeen with them that they occupied too much space in the mantel or were arranged over the top of the mantel.

By my construction l am enabled to secu re a very light and compact burner, one that if liable to get out of order is very easily taken down and rearranged and also very easy to make and clean, as any of the plugs which close the drilled holes may be withdrawn, they being screwed in, and then any of the holes can be reached and readily cleaned ont.

What I claim isl. In a hydrocarbon-burner, the combination of an inlet-pipe for hydrocarbon, a solid rectangular frame bored at one point to connect with said inlet, and bored to form a rectangular tube, a stand-pipe erected thereon, having therein two passage-ways connected at the top thereof, and each connected at the bottom of the stand-pipe with a passage respectively upon either side of the frame of the generator through which vapor is discharged, a surrounding casing, and means whereby the flame is compelled to surround the stand-pipe, substantially as described.

2. In a hydrocarbon-burner, the combination of an inletpipe for hydrocarbon, a solid rectangular frame bored at one point to connect with said in let, and bored to form a rectangular tube, a stand-pipe erected upon the top thereof, having therein two passage-ways connected at the top and connected at their bottom with the passages respectively upon either side of the rectangular space formed by the frame of the generator through which vapor is discharged, a surrounding casing, means whereby the dame is compelled to su rround the stand-pipe, and a mantle surrounding said frame, substantially as described.

3. In a hydrocarbongenerator, the combination of a rectangular frame, having a passage-way through each of its sides and a central extension thereof at the upper end, consisting of a single piece with two passageways therein connected at the top, and connected with a source of supply of hydrocarbon at one of the sides of the rectangle, an interior inlet communicating with said pas sages leading into the rectangular space formed by the generator, and a valve governing said inlet, substantially as described.

l. In a hydrocarbon-burner, the combination of a rectangular frame, having a passage- Way through each of its sides and a central extension thereof at the upper end, consisting of a single piece with two passage-ways therein connected at the top, said passage being connected with a source of supply of hydrocarbon at one of the sides of the rectangle, and an interior inlet leading into the rectangular frame, a valve governing said inlet, a casing F, having air-passages at the bottom surrounding said rectangular generator and forming a mixer, the upper portion of which extends beyond the rectangular portion of the generator and partially inclosing a pcrforated central connection, substantially as described. i

5. A rectangular hydrocarbon-generator cast in one piece and containing at its upper end when arranged for use, a stand-pipe with two passages bored to communicate with the two sides of the rectangular generator, plugs closing off the bored holes in such manner as to form a con tinnous interior passage to which access may be had at ditferent points for cleaning, substantially as described.

In testimony whereof I have signed this specification in the presence of two witnesses.
