GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 554,924, dated February 18, 1896.

Apphcation filed August 10, 1895. Serial No. 558,859. (No model.)

T0 all whom t may concern.

Be it known that I JOHN FRIEDLANDER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Gas- B urners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in gas-burners; and it consists in the novel arrangement and combination of parts more fully set forth in the specication and pointed out in the claim.'

In the drawings, Figure I is a vertical section of the burner on the line oo of Fig. 2. Fig. 2 is a top plan view thereof. section on line'y y of Fig. l. Fig. 4is a section on lineas of Fig. l, and Fig. 5 is asectional detail of a modified form of arm forming a part of the main chamber.

The object of my invention is to construct a gasfburner which is designed to iit over an ordinary shell and tip, the purpose of the new burner being to fully utilize and consume without waste all the gas that may escape from the tip over which it isA placed. This purpose is made effective by superheating the gas fed by the inner tip to the chamber of the burner, and so distributing the gas as it escapes from the inner tip that every portion of it may be superheated before it is ignited at the open end of the new burner. By reason of the thorough superheating of the gas the capacity or size of the new burner may accordingly be increased beyond that of the tip over which it is placed. The superheatin g and distribution are accomplished by a construction which I shall now describe in detail.

Referring to the drawings, l represents the shell of an ordinary gas-burner, and 2 the tip thereof. Over the former is adapted to be passed the tubular extension or body portion 3 of my improvement, said extension being expanded into an enlarged chamber 4 divided longitudinally into two sections by a diaphragm 5 disposed about the medial line of said chamber, said diaphragm being provided with openings 6 to allow for the passage of the gas from one section to the other.

Formed integrally with the diaphragm is a Fig. 3 is a central deflecting-cup 7, which is adapted to be superposed immediately over the tip 2.

The lower edge of the diaphragm forms a contracted annular passage 8 between it and the inner surface of the lower section of the chamber 4, whereby, as the gas escapes from the tip 2, it is uniformly distributed and forced into and through the lower section and caused to hug the walls of the chamber and positively directed to the openings 6 of the diaphragm. The upper section of the chamber 4 constitutes the expanding-chamber, being open at the top, said openin g being surrounded by an annular ridge or wall 9 designed to rmly hold a tip I0.

Forming a part of the upper section of the chamber 4 and disposed diametrically opposite one another on opposite sides of the ridge 9 are the preferably hollow exten sions or arms 1l, as seen-in Fig. 5, said extensions serving to store or hold a portion of the gas contained in the chamber 4, and being so disposed as to permit the bottom of the iiame to impinge against them. By this contact with the arms the flame is steadied and at the same time it heats the arms to a temperature at which the gas contained in the chamber 4 becomes thoroughly superheated and` expanded. Under these conditions the size of the outer tip -10 can be much greater than that of the tip 2, this arrangement resulting in an even iiow of gas from the tip 10, a flow which is devoid of unnecessary pressure and resulting in a -flame that consumes every molecule of gas fed to it. At the same time the' iiame is exceedingly steady, being made so by the arms 11 against which it impinges.

The arms 11 may be solid instead of hollow, as seen in Il', Fig. l, in which case the solid metal thereof conducts the heat to the chamber 4 and heats the gas therein.

Having described my invention, what I claim is- A gas-burner comprising a suitable shell and tip, a casing or extension adapted to be passed over the same, a chamber forming an enlarged continuation of the extension, a perforated diaphragm dividing the chamber into two sections, a deflecting-cup facing the lower section formed with the diaphragm and adapted to be superposed over the tip, a con- IOC) traeted passage formed between the lower edge of the eup and the inner surface of the lower section of the chamber, a central opening formed in the upper section of the ehamber, an annular ridge bounding said opening and adapted to retain a terminal tip, lateral arms or extensions forming a part of the upper seetion of the Chamber, said arms being diametrieaily disposed with reference to each ro other and adapted to have the lower edge of the iialne impinge against them whereby the same are heated and the within the upper section of the chamber expanded, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
