VAPOR-BURNER FOR PETROLEUM-STOVES.

SPECIFICATION forming part of Letters Patent No. 595,795, dated December 21, 1897.

- Application filed June 12, 1897. Serial No. 640,5 72. (N model.)

To all whom it may concern.- y

Be it known that I, J OHAN VICTOR SvENsoN, a subject of the King of Sweden and Norway, and a resident of Stockholm, Sweden, have invented certain new and useful Improvements in Vapor-Burners for Petroleum-Stoves, of which the following is a clear, full, and exact specification.

This invention relates to a vapor-burner for petroleum-stoves arranged so as to cause the escaping vapor to be burned silently or at least without appreciable noise, the construction of the burner being such as to make it more efficient and more easily kept clean than other burners of the same kind. The silent burners already known consist, essentially, of a cup placed above the usual rin -shaped vaporizer and provided with a central funnel, at the middle of which terminates the upper end of a tube situated directly above the nozzle through which the vapor escapes, said funnel being surrounded at some distance from it by another funnel or bonnet resting on the bottom of the cup and provided at its lower edge with apertures, through which the vapor escapes, this vapor being subsequently ignited, forming an annular flame which projects upward, grazing along the edge of the cup, which shapes the flame. The vapor flowing upward through the tube is compelled by the exteriorbonnet to change its direction so as to move downward before escaping from the burner for ignition, the absence of noise during the combustion being due to this change in the direction of the vapor. Such a burner, however, is not as eflicient as might be desired, owing to the fact of the vaporizer being situated below the flame, and consequently the heating of said vaporizer being effected principally by the heat conducted through the metal of the cup. Moreover, in case the liquid heated on the stove boils over this liquid is apt to collect in the cup and here form a coating which it is almost impossible to remove.

In the annexed drawings there is illustrated in Figure 1 a vertical section, and in Fig. 2

a plan view, of the burner which forms the object of the present invention, and the purpose of which is to obviate the difficulties referred to.

1 1 are the usual rising-tubes for the oil.

the ring 11.

2 is the horizontal vaporizing-channel or vaporizer, (which is shown annular in the drawings,) 3 the tubes leading to the nozzle 4, and 5 the tube located directly above the nozzle. This tube is attached to asurrounding horizontalmetal disk 6, which extends beyond the burner-tubes 1 3. The tube 5 is surrounded at some distance from it by a bonnet 7, the top of which reaches above the upper orifice of the tube 5 and is closed, for instance, by a cap 8, so as to be more easily accessible for cleaning. The lower edge of this bonnet 7 is situated at a slight distance above the disk 6 and is fixed to a second horizontal metal disk 9, which also extends beyond the tubes 1 3, terminating, however, a little inside the circumference of the disk 6. The two metal disks 6 and 9 are joined in such a manner that the current of vapor passing between them can escape only through theannular opening between their outer edges, the disks for this purpose being suitably united by means of short tubes 10, surrounding loosely the tubes 1 and 3. Finally, there is placed above the annular opening between the disks 6 and 9 a perforated ring 11 for the escape of the vapor, said ring preferably being made of rounded cross-section. The vapor rushing out through the nozzle flows upward through the tube 5, together with the air swept along, passes then downward between the parts 5 and 7 and, continuing its course, horizon tally between the metal disks 6 and 9, finally escaping through The flame formed is here brought into contact with and caused to act upon the vaporizer above it, and as a result the latter will be subjected to a much intenser heat than when located below the flame, the efficiency of the burner consequently being materially increased.

The burner just described dispenses with the cup forming a part of the silent burners previously known, thus obviating the disadvantage-referred to in connection with said cup.

It is evident that the vaporizer need not necessarily be of annular shape nor consist of one or more tubes arranged around a central orifice, for it might consist of a retort or plate provided with a series of passages. The shape of the vaporizer is quite unessential to the invention, though that shown in the drawings may be considered to best answer the purpose.

It is also easily understood that the upper edge of the tube 5 may be made to reach to approximately the same level as the top of the bonnet 7 if the tube be provided at the top with perforations furnishing free passage for the vapor to the space between the tube and the bonnet.

The burner portion, including the tubes 5 and 7, can be supported in any suitable way such, for instance, as by the cap 8, resting upon the vaporizing-ring 2.

Having now particularly described and ascertain ed the nature of my said invention and in what manner the same is to be performed I declare that what I olai n1 is A vapor-burner comprising the vaporizing chamber, the nozzle,the tubes extending from 20 V J OHAN VICTOR SVEN SON. Witnesses:
