SPECIFICATION forming part of Letters Patent No. 364,101, dated May 31,1887.
Application filed August 5, 1886. Serial No. 210,079. (No model.)
bustion of the gas is enhanced, an intenseheat obtained, and objectionable accumulations of unconsumed carbon prevented.
In the accompanying drawings, forming part of this specification, Figure 1 is a vertical sectional elevation of a burner embodying our improvements. Fig. 2 is a sectional plan of the construction shown in Fig.1.
Similarletters of reference indicate similar parts in the respective figures.
Heretoforein burning natural and other gases imperfect combustion has ensued,by reason of an incomplete mixing or commingling of the air and gas, this difficulty resulting in the deposition of unconsumed carbon in the burner andthe obstruction of the passages therein. By our improvements we obviate the difficulties noted.
A refers to a central tube, around which are mounted a series of concentric walls or partitions, B B B inclosing annular spaces or chambers cl d d, the tubeA forming a central passage, a. The upper part'of said tube A extends up beyond the edges of the walls or partitions B B B", where it is extended laterally to form a deflector, C. It will be seen, Fig. 1, that the first annular space or chamber, d that is to say, the one adjacent to the central tube, A--is provided at its lower end with openings 0", communicating with the pipe F. The space or chamber (1 is closed at its lower end at c, and has an opening in the wall or partition B connecting with the gas-supply pipe (Z. The outer space or chamber, (1 is the shortest in length, and communicates with the pipe F by means of the openings 6.
Our improved burner being especially designed for application to stoves and heaters of various kinds using natural or other gas as a fuel, Fig. 1 shows the position of the burner relative to the grate surface D. The air is sup plied through the pipe F, which incloses the lower ends of the vertical partitions B B B The front end of the pipe F communicates with the atmosphere through the furnace-front G, and said end is covered by a gauze shield or perforated guard, g. The gas-supply pipe d passes up through the grate D to the burner. In existing forms of gas-burners for stoves great danger is experienced when the gas is cut off, which generally causes the flame to flash back and out of the air-pipe with a loud report. By placing the gauze shield or'perforated guard g in the air-pipe the flame will be extinguished when it reaches said shield or guard.
In operation the air can only reach thepoint of combustion by passing through the perforated guardg. The gas is admitted to the annular chamber or space d, andissucs from the upper end thereof, where it strikes the under side of the deflector O. The air, traveling in the same direction as the gas, passes up the an-- nular passages d d, strikes the deflector, and completely mixes with the gas. Combustion of the mixed air and gas is carried on beneath the deflector, and a lateral spread being effected by the deflector, a steady and uniform burning is produced and an undue concentration of heat prevented. The air also passes up the central passage, (1, of the tubeA andIcomes in contact with the flame on the upper side of the deflector G, and thus causes a more perfect combustion. This additional current of air, mixing with the flame above the deflector, .is particularly effective in burning natural gas. Natural gas is usually supplied under a very great pressure, and large quantities of it therefore pass off unconsumed, owing to the insufficiency of the supply of atmospheric air necessary to render combustion perfect. plying the additional current of air, as described, the combustion is rendered more perfect, and hence a greater degree of heat is attained.

In a burner for gas, the main air-tube, the gas-supply pipe located within and passing through said air-tube, and partitions form- 'ing annular spaces for conveying air and gas below the deflector, the air spaces communieating with the main airtube and being located one on each side of the gasspace, com
