BURNER FOR BURNING GASEOUS FUEI SPECIFICATION forming part of Letters Patent No. 560,458, dated May 19, 1896. Application filed October 22, 1892. Serial No. 449,666. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY ADLER, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Burners for Burning Gaseous Fuel; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to burners for burning gaseous fuel, and it is especially adapted for use where natural gas is the fuel employed. One of the great objections to burners heretofore in use, and one which has been a fruitful source of annoyance and waste of gas, has

been the ease with which the gas was ignited in the mixing-chamber by the flame being forced down into the mixing-chamber by a sudden draft on the top of the burner, or from other causes. My invention is designed to obviate this objection and to provide a gasburner which is cheap in construction, and one in which the gas and air are thoroughly intermingled before they are burned, thus se-- curing perfect combustion; and it consists, generally stated, in a gas-burner having a burner-chamber, a mixing-chamber below the burner-chamber having air-openings therein, and a cone-shaped plate having upwardlyconverging sides within the mixingchamber above the air-openings.

It also consists in certain other details of constructionand combinations of parts, all of which will be more fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use'my invention, I will describe the same more fully, referring to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view of my improved burner. Fig. 2 is a longitudinal central section of the same. Fig. 3 is aplan view thereof and Fig. 4 is a cross-section on the line 4 4 of Fig. 1, looking toward the plate k.

Like letters of reference indicate like parts in each. I

As illustrated in the drawings, I have shown a form of burner which I deem most suitable for usein grates, stoves, &c. The burner ais preferably formed of sheet metal and consists of the longitudinal burner-chamber I), having closed ends 0 c and perforations d in the top thereof for the escape of the gas. Depending from the burner-chamber b is the mixingchamber 6 for mixing the gas and air before they pass'into the burner-chamber and thence to the perforations d to be consumed. This mixing-chamber e is preferably formed in the shape of a truncated cone, its upper or smaller end being provided with the opening 6 for the passage of the mixed gas and air into the burner-chamber b and its bottom or larger end being closed by the plate f, carrying the nipple g, which nipple is provided at its upper end with a jet-hole 77. for the escape of the .gas and at its lower end is threaded, as at 2 for the reception of the gas-supply pipe j.

Mounted and secured within the mixing-' chamber 6 and dividing the same into the compartments m n is the plate is, which is also made in the form of a truncated cone with upwardly-converging sides and is provided with the opening Z in the top thereof for the passage of the gas and air into the upper com- The plate 719 is of partment m of the mixer. such a shape and is secured in the mixerchamber 6 in such position as to form an annular space or pocket 19 between its outer surface and the inner sides of the mixing-chamher, which assists materially in preventing 8o the flame from being blown down through the opening Z in the top of said plate into the lower part of the mixing-chamber, it'being obvious that in the event of such an occurrence the flame will strike the upper surface of the plate 8 5 and will be deflected away from instead of toward the opening Z in the top thereof. Below the plate k are the air-openings 0, formed in the sides of the mixing-chamber.

In the operation of my improved burner compartment m the mixed gas and air will IOO spread somewhat before passing through the opening c at the top of the mixing-chamber,

As it passes through 9 5 at which point they are still more thoroughly intermingled and pass into the burner-chamber, from which they escape through the perforations d to be burned.

By the use of my improved burner the gas I and air are very thoroughly intermingled before they are burned and perfect combustion and great heat thereby secured.

Practical use and experience have proved that this is the most desirable burner on the market for the burning of natural gas on account of the great suction of air into the mixing-chamber caused by the position and peculiar shape of the plate interposed therein, which also render it practically impossible to ignite the gas in the mixing-chamber with a lighted taper or match, or from the flame being blown down into the mixing-chamber by drafts or by other causes.

Modifications in details may be made Without departing from the spirit of the invention or sacrificing any of its advantages.

I claim In a gas-burner, the combination of a gassupply pipe, a burner-chamber, a mixingchamber having air-openings in the sides thereof, and a concave or cone-shaped plate,

HENRY ADLER. \Vitnesses:
