STEPHEN B. MORSS, OF RAHWAY, NEW JERSEY.

HYDRooARBoN-LAMP.

SPEGIFIGA'ION forming part of Letters Patent No. 691,068, dated January 14, 1902.

Application filed April 20. 1899. Serial No. 713,723. (No model.)

T l/ZZ when?, it may col/warn.

Be it known that I, STEPHEN B. MORSS, a citizen of the United States, residing in Rahway, Union county, New Jersey, have invented certain new and useful Improvements in Hydrocarbon-Burning Lamps or Heaters, of which the following is a specification.

My invention relates to improvements in the class of lamps or heaters in which vapor or gas is evolved from hydrocarbon oil and commingled with air, the mixture to be burned in the form of a sootless or blue flame; and the object of my invention is to provide improvements in the devices that generate the vapor or gas.

In carrying out my invention I provide a primary combustion-chamber in which is located an oil-burner of anysuitable type adapted to produce what is known as a white flame, and in. conjunction therewith I use a wick that leads to'an oil-font, which wick is in proximity to or overlies said burner, so that the heat from the flame will cause vapor or gas to be evolved froml the oil carried up by the wick. Said Wick is protected from the flame, and by preference the Wick is guided by a metallic duct or tube which is provided with one or more perforations or openings for the escape of vapor orgas, whereby the heated metal of the duct assistsin evolving the vapor or gas from the oil. I also preferably surround ihe `perforations or openings of the duct with a band of, metal to prevent the llame from` reaching the gases or wick. The combustion-chambeis connected with a suitable air and vapor or gas mixing chamber, to Which a secondary'or supplemental burner is connected in any suitable or Well-known manner.

The invention also consists in the novel details of improvement and the combinations of 'parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a vertical section of a lamp embodying myimprovements. Fig. 2 is a cross.- scction on the line 2 2 in Fig. l; and Fig. 3 is a section substantially on the line 3 3 in Fig. 1, the shield for the burner being removed. i

In the accompanying drawings, inwhicb `similar numerals of reference indicate correspending parts in the several views, 1 indicates a suitable oil-font, and 2 is a burner of suitableconstruction adapted to be connected therewith, being shown` provided with a perforated top 3, air-inlets et, and a wick-tube 5, adapted to receive a wick 6, that passes in to font 1, 7 being an ordinary toothed wheel for controlling the wick.

S is a shield or air-guide surrounding the upper portion of tube 5 to cause the proper burning of a dame at the end of wick 6 in well-known manner.

The above-described parts may generally he in any well-known or suitable construction adapted for producinga white Haine from hydrocarbon oil. Above the perforated top 3 I provide a combustion-chamber composed of a shell 9, that is shown resting upon the top 3, the latter having a flange or shoulder 3n to hold the shell 9 in position, whereby the shell 9 is removable; but these parts may be otherwise arranged and connected, if desired. The shell 9 is provided with an opening 9, adapted to be closed by a shutter or the like l0, suitably arranged thereon to permit access to the interior of the shell, as for lighting the wick 6.

The oil from which vapor or gas is to be produced is conducted from the font by means of a feeding-Wick located in proximity to, but preferably across the top of the iame from, wick 6, and the feeding-Wick is protected from the flame by a partition. For these purposes I have shown a duct or tube ll, illustrated as curved atits central portion and provided with two depending leg portions that pass through the parts 2 and 3 and open into the font l, whereby a wick can be located in said tube and depend at both ends into the font. The upper surface of the tube or duct ll at the part 11L that crosses the top of tube 5 is provided With one or more openings or apertures llb (see Fig. 2) for the escape of vapor or gas that is generated by the oil carried into the duct by the wick. I have shown the wick Gas depending from tube 5 and passing over a pin or guide l2 in font l, thence up through d uct 1l, across over tube 5, and down through said duct and depending into the font 1. By this means as the wick is consumed at the burner-tip and is fed IOO Y sented over the llame.

forwardly new parts of the wick will be pre- It is evident, however, that separate wicks can be used-that is to say, one wick can depend from the tube and the other wick can pass through the duct 1l and depend from both ends thereof,

vextends upwardly and conducts the vapor g away from the zone'of `the dame.

The combustion-chamber 1n which the va- Y por or gas is generated is to be connected with Iable or well-known manner.

a'gvapor or 'gas and air mixing chamber, the latter' beingfconnected with ay supplemental burner, all of which' may be made in any suit- I have shown the shell 9 as connected by'tubes 91 with a 1niXing-chamber 13, shown provided with air? inlets 13, a burner 14 beingconnected with the latter.y

From the foregoing it will be understood Y that when'it is desired to produce vapor or ber.

rgas from hydrocarbon oil the wickis lighted at the burner-tube 5 and the sizeof the flame cau be regulated in well-known manner. The heat from the llame will act upon the oil conducted by the wick within the heating zone of the fiame in such manner as to cause vapor or gas to be evolved therefrom, and the proportion of such vapor or gas which is evolved willbe determined, more or less, by the size of the Haine used in the combustion-cham- The vapor or gas 4Vthus'evolved passes from the duct or tube l1 through its openings 1lb up-into the mixing-chamber, and it is then burned at a suitableburner in the y yform of'a sootless or blue flame either for heating purposes or for producing alight, as

'from a refractory mantle l5 in well-known lnanner.

The advantages of my improvements are 'A that there is no necessity of smothering the' y:flame that produces thel heat for evolving the vapor or gas, and as the vapor-producing. flame is'not smothered the same will bestrong and will therefore not be liable to fluctuations due to changes in air-circulation around the lamp, and, furthermore, the heated metal of the partition, duct, or tube ll in contact with the oil-feeding wick will have an effect more fully to evolve the gases from the oil. I thus dispense with valves and adjustable devices for feeding the oil, the auxiliary or feeding wick being automatic in its action as to the supply of oil, the height of the heating-flame regulating the quantity of vapor o gas evolved.

In my improvements there is very little unconsumed products of combustion passing away from the generating or heating flame, and the chamber within band 11C, in which the'vapor or gas is evolved from the feeding or auxiliary wick and allowed to escape, is almost entirely separate from the combustionchamber. y

I do not limit my invention to the precise details of construction shown and described,

as they may be varied, as necessity or prac-- tice may suggest, without departing from the spiritof my invention.

Having now described my invention, what I claim is-- y l. In a lamp or heater of the character described, the combination of a burner having a'l'wick-tube, and a tube or duct having a portion overlying thewick-tube 5 and two depending portions lying on opposite sides of wick-tube 5 and opening downwardly, and a wick extending continuously from Wick-tube 5 to an oilfont,thence upinto and through the duct andfdepending therefromI into the oil, the overlying portion of the duct having means to permit the escape of vapor, substan-v tially as'described. l
