To all whom it may concern: 7

Be itknown that I, J OHN ARTHUR JANss'oN,

. of Boston, in the county of Suffolk and State of Massachusetts, have constructed as to prevent the flame from striking the middle of thelniidr rim-race of the pot, and yet at the same time afford a strong flame immediately about the ceriten-and the flame also should be capable 'of'a'dj ustment.

Y It is also desirable that-the burner be proout of the pot or tected from the metal, which often splashes nozzle, and if it happensto strike the gas-exit clogs 'itso that it gives an uneven flame. With these facts in mind I have invented the-device shown in the'd-rawings, in whicl1 v Figure 1 isalongitudinal section of a burner embodying my invention, Fig. 2 being a detail showing the means for closing and protecting the end of the burner and adjusting its flame, Fig. 3 being a cross-section on line 3 3 of Fig. 1.

A is the burner, which is provided with a branch a, carrying the nipple a, which is adapted to heat the nozzle of the metal-pot.

A The burner A is provided on its interior with means for supporting a perforated disk B,

known as a mixing-disk, these means he- 111g,

b driven through the wall of the burner. A shoulder on the interior of the burner would answerthis purpose. burner is-partially closed in order to provide a flame of proper shape and size, aswell as to protect the pump, which is-located in the bottom of the pot and directly above the burner, and for this purpose I have shown a C, which is adjustably supported in'tlre burner. For this purpose I have pro vided a shoulder 0 within the burner, upon invented a new and, useful improvement in gas-burners 1nore -eswith a pipe .F,

as shown in the drawings, a number of;

The upper end of the understood.

to its air and gas reservoirs through the joint. H, the air and gas pass up under pressure which rests a disk D, provided with a series of openings d to allow the free escape of gas through it, and a screw D, connecting the disk D with the protector C. The protector thick, so as to fit well within the mouth of the burner, the edge of which is beveled, so that a passage E is provided for the gas,which will cause it to spread and give a flaringflame. The protector, being larger in diameter on top than the mouth of the burner, will overhang.

'0 is slightly larger in diameter on its upper side than the mouth of the burner and quitethis passage and so protect it from any drops of metahas well as protectthe' under surface of the middle of the bottom of the pot overwhich the pump is located. Thsscrsw'nf-is attach to the disk D and passes up through the protector C, which is threaded, so thatits posi-.

tion may be, adjusted thereon with reference to the disk D, and hence with reference to the mouth of the burner. hold it in place. The advantage of this construction is that if the burner is not giving a proper flame it 's' only necessary to lift the protector, C and disk D outof the upperend of the burner and adjust the protector on the screw D' and set it by the nut C, so that when the protector is replaced it will be. nearer to or farther from the mouth of the burner, and

hence control the amount of gas escaping therefrom.

The lower end of the burner A is connected at' its lower end, by means of which connection may be made with a rubber tube G. The

lower end of this rubber tube fits over a cor-.

responding enlargement 9 upon one, branch h of a coupling H, the three'arms oLwhieh are located at equal distances about the central chambenwhichj is spherical. The other branches h h are connected, respectively,

"at its lower-end G is a set-nut tohaving a slight enlargement f with air and gas reservoirsff-rom which air I and gas are supplied under pressure.

The operation of this-burner will be easily The burner being connected up into the spherical chamber h therein, where they get a preliminary mixing, due to the fact tively-slight angle to each other, They pass through the tub V for to make, say',' six'fcet long 5 itself, where the perforated disk B,.oflering a certain resistance to its onward movement, causes a'more intimate mixture of '-the gas and air. The-mixture passes out through the openings in this let E. If the flame is too large, the protector C and its disk D are removed, and the adj ustnient of these parts is made to cause the pro- .r 5 tector C to approach more nearly the disk D, and hence the upper edge ofthe burner'A. If, on the contrary, the flame is not large enough, the Opposite course-is pursued, so as, E togive more flame.
