SPECIFICATION forming part of Letters Patent No. 506,201, dated October 10, 1893.

Application filed September 28, 1892. Serial No. 447,207. (No model.)

To all whom it may concern:

Be it known that I, GUsTAv BARTHEL, a subject of the King of Saxony, residing at Dresden, Saxony, in the German Empire, have invented certain new and useful Improvements in Lamps or Burners, of w. ich the following is a specification.

My invention relates to vapor burner adapted for burning spirit or hydrocarbons without the employment of a wick the spirit being in practice adapted to be supplied under pressure and caused to burn inv a blue flame, and among the objects in view is to provideaburner of the class described by which I avoid the disadvantages resulting from the employmentof the oils usually burned in such burners (such as benzine, ligroine or petroleum spirit) in combination with the usual wick, which latter soon becomes clogged with resinous residues.

Y A further object of my invention is to replace the oils mentioned by spirit which is cheaper and comparatively safe, and with these'objects in View, the invention consists in the novel construction, arrangement and combination of parts as hereinafter fully described, illustrated in the drawings and pointed out in the appended claim.

In the drawings:-Figure l is a vertical section of my burner adapted for cooking purposes. Fig. 2 is a like view showing a' soldering tool or iron applied thereto. Figs. .3 and 4 represent the wire gauze roll or reel in elevation and in section. Fig. 5 is a section of the said roll or reel and burner pipe.

It is well known that the vapors arising from spirit have the property of very rapidly settling down and condensing and it was therefore necessary to devise special means to meet this difficulty. This result is attained in the present invention by making provision fora rapid and uniformly distributed evaporation while a certain counter pressure is allowed to act upon the vapors whereby their settling down is prevented. The means employed for accomplishing this object may vary but practical experience has shown that in order to insure a uniform conduction of heat and evaporation rolls of thin wiregauze should in preference be employed, While in Order to produce the required pressure it is only necessary to raise the spirit reservoir to the required level, into which reservoir, which may be connected with the burner by any suitable means, air may be forced by any suitable forcing device. y

Into a suitable support or base l, there lis screwed a supply pipe l, provided with a handle 1b and a burner pipe 2. The latter is by an intermediate piece 3, divided into two sections the lower being the evaporation chamber and the upper the vapor combustion chamber. The piece 3 is provided with a narrow opening or mouth 4 having a small tube or nozzle 5 that maybe fitted to it or to the pipe 2 as shown and into which nozzle 5 a spindle 6 with a tapering point is inserted from the outside and projecting 'through an opening in the pipe 2, and adapted to close and open one end ot passage 4, and thereby control communication between the lowery evaporation chamber kand the upper vapor combustion chamber. Suitable packing is employed for making a tight joint between the nozzle and spindle. x

The pipe 2 is provided with openings 2b for admitting air. The lower end of pipe 2 is closed by a perforated bottom 7. Above it is arranged the heat-distributor occupying the whole of the evaporation-chamber, which distributor in the present case is formed of a roll or reel 8 of thin wire-gauze.

In starting the burner, the pipe 2 is first heated in the well-known manner by spirit poured into the cup or basin 9 securedto pipe la. Then by means of an adjustable cock (not shown) arranged in the supply pipe, as much spirit is admitted into the evaporation chamber as can be instantaneously evaporated. The spirit being introduced under pressure becomes distributed throughout thev whole of the wire-gauze while at the same time the condensation of the vapors is obviated by the fact that the vapors remain in contact with the heated wire up to the very moment when vthey are allowed to escape through passage 4. By means of spindle the escape or discharge of the gas may becontrolled if desired but this can also be accomplishedby the cock of the supply pipe il. e. by simply not admitting more spirit and consequently not allowing more oi it to evaporate roo than is actually required. This is important dering purposes, for in this manner no liquid will be left in the apparatus while it is capable of being turned in anyrequired direeton. By raising or loweringthespirit reservoirthe pressure may be correspondingly increased or diminished, and the flame regulated.

Instead of the reel of wire gauze Separate pieces of wire or thin rods may be employed to fill the evaporation chamber, this, arrangement offering the advantage of facilitating' the cleaning of the burner.

In Fig. 2 I show a soldering tool l0 removably secured to a standard li which is suitably mounted upon pipe 2.

What I claim is- The combination with a base l, ot a supply pipe ln secured to said base, a burner pipe 2, also secured to the latter and in Communication with the supply pipe, a partition 3 arranged in the burner pipe, a port 4f in said partition and providing communication between the two chambers of the burner pipe, a nozzle secured to the pipe 2 and provided Withta spindle G having a tapered point adapted to open and close the port et, Wire-gauze 8 arranged in the lower chamber of the burner pipe and extending from thelower end thereot up to a point in close proximity to the partition 3, air-openings 2d in the latter above the partition 3, a basin 9 secured to the said burner pipe, and a handle secured to the base all arranged aS and 'for the purpose set forth. In testimony whereof I have hereunto set my hand in presence of two witnesses.
