HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented April 2a, 1908.

Application filed February 24, 1903. Serial No. 144,557.

ers ada ted to vaporize a liquid and fluid to burn t ie resultant vapor; and it particularly relates to burners of this sort, which are used for heating the steam generators on automobiles, launches, traction engines, and the like.

In order that such burners shall be practically useful for such purposes, it is necessary to provide means for shutting off the main burner, as wheri the automobile is to stand immovable for a while; and means for causing the automatic lighting of said burner when it is turned on, as when it is desired to run the automobile, and means, which, under all of the conditions incident to practical use, will vaporize an adequate quantity of the fuel without any such destructive distillation of the latter as will cause carbon and other products of such destructive distillation to be de ositedin said vaporizer, with the result of c ogging it up and rendering in- 'eflicient to a greater or less-degree.

The invention may be here summarized as consisting in the construction and combination of parts hereinafter described anddefinitely pointed out in the claims.

In the drawing, Figure 1 is a plan view of the burner and its associated parts; Fig. 2 is a sectional elevation of the same; and Fig. 3 is a view of the apparatus shown in Fig. 1, the view being in near said figure.

Referring to the parts by letters, A represents the main burner which may .be of any suitable specific construction. [The inlet to the main burner is through a mixing tube a, which may be of the usual forrh.

"B represents a sub-burner: or pilot light which projects up through the main burner. This sub-burner may also be, of any suitable construction.

the direction of thearrow...

C represents avaporizer which lies partly over the main burner and partly over the sub-burner, by which it is heated when the main burner is turned off. This vaporizer as shown in the drawing, is a casting containing a U-shaped passage indicated by dotted lines in Fig. 1. The outlet or discharge end of this vaporizer has a pipe 0 connected with it; and this pipe terminates in a nozzle 0 arranged to discharge into the open end of the mining tube a. The inlet end of the vaporizer is connected by a pipe F with the fuel supply tank (not shown). pipe F, is a valve casing D containing the main valve (1. This-casing also contains a second valve G; and the closin of either of these valves prevents the flow 0 fuel through the feed pipe into the vaporizer. This valve G is an automatic valve, which, in the'construction shown, is lifted from its seat by a bell crank lever K, and is moved to its seat by gravity or otherwise whenthe lever is allowed to move in the reverse direction. This bell crank lever is operated to lift the valve by a thermostat N which extends into the generator. The generator, which is referably, but not necessarily, used witi this Connected into this feed burner is that which is shown in my prior patentNo. 659,837; and the tube J, in which the thermostat lies, is a part of this generator.

The specific means employed for causing the automatic operation of the valve G is not at all material to the present invention. Such valves are sometimes operated by thermostats in the generator, and sometimes they are operated by mechanism which is caused to operate by the pressure of the steam in the generator. Such devices are well known in this art, and it ls-of no consequence to this invention what .kind of automatic valve 0 crating mechanism is employed, or w ether such mechanism is caused to operate by the pressure or by the temperature of the steam. In fact, any automatic valve is not essential to the generic invention. It will be noticed that in the discharge ipe c of the generator there is no valve. T e part marked 0 is not a valve, ,but simply a movable plunger having a pointed end which is designed to be moved off of either valve d or G in said casing does not interfere with the flow of the fuel to said sub-burner. The sub-burner is always light ed when the automobile is fired up; and therefore the apparatus is ready foroperation whenever the main burner valves are opened. Since this sub-burner is in heating relation'with the va orizer, the latter will be subjected to that eating influence at all times whether or not the main burner is turned on. If the fluid fuel were allowed to flow into this vaporizer and were held therein by some valve near its outlet end, this fuel, when so confined, would, after awhile, be heated to such a temperature by the subburner as would result in a destructive dis-i tillation or cracking of the oil, and the con sequent deposition of carbon in the vaporizer. Very soon the vaporizer would become clogged up and practically useless. By the arrangement of parts, however,

'shown in the drawin and above described,

when either of the va ves G or d are shut off, not only is the supply to the main burner cut ofi, but the supply of the liquid to the vaporizer is also cut oil. Such oil as may be between said valve and the discharge nozzle 0, when said valves are closed, will be vaporized and burned, but thereafter the vaporizer'will stand empty until the main burner valve is again opened. Standing thus empty the vaporizer will be, heated, and so when the valves d and G are again opened, and the fluid fuel flows into this hot vapo rizer, it will be immediately vaporized, and the vapor will flow into the main burner. As it emerges from said'burner, it will be lighted by the pilot light. The heat of the main burner will thereafter maintain the. necessary temperature of the vaporizer to vaporize the liquid fuel as it flows through it. Another advantage of the construction shown is that it permits the removal of the vaporizer for the purpose of cleaning it, and its subsequent replacement. Obviously this would not be practical if the vaporizer remained filled with the combustible fluid when the main burner were turned off. The removal of the vaporizer shown requires only the unscrewing of the single coupling nut by which the vaporizer supply pipe 0 is connected with the valve casin D. This being unscrewed the vaporizer, t e nozzle 0 and the feed pipe 0 come out as a single piece.-

. To replace the vaporizer one inserts the boss therefor, a va orizer feed pi e on. the inner end of said vaporizer into a hole in a fixed support P, and then screws on the coupling nut 9 The parts are then in readiness for use. Having described my invention, I claim: 1. The combination of a main burner-having a mixing tube, a casing above the main her, wit 1 a feed pipe, a valve casing secured to said feed ipe, a vaporizer feed pi'e which extends tliirough a hole in the we of the combustion chamber and separably connects the vaporizerwith said. valve casing, a valveless pipe connected with the discharge end of the vaporizer and extended out through the same hole in the wall of the combustion chamber and terminating in a nozzle which discharges into said mixing tube, and an independent feed pipe for said. sub-burner, sub-- stantially as specified.
