GAS-BURNER FOR STOVES OR HEATERS.
SPECIFICATION forming part of Letters Patent No. 615,737, dated December 13, 1898.
Application filed MR101131, 1893- Serial No. 675,983. (No model.)
' provide a gas-burner of extreme simplicity and great efficiency and which will effect an economyin the consumption of gas and which shall consist of few parts readily assembled and taken apart.
To these ends my invention consists in the features and in the novel construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings,
forming a part of this specification, wherein Figure l is a vertical longitudinal sectional view of my improved burner, and Fig. 2 is a perspective view of the parts detached.
Referring to the drawings, the numeral 1 indicates the burner-tube, which may conveniently and cheaply consist of a section of gas-pipe of suitable length. The burner-tube is exteriorly threaded at its opposite ends, as at 2, and between its threaded ends is provided with a plurality of perforations 3, which are formed in the upper half or circumference of the burner-tube only. As shown, the
burner-tube is arranged horizontally and is closed at one end by a screw-cap 4:. Over the opposite threaded end of the burner-tube is screwed a nipple 5, designed to connect with a gas-supply pipe and having a reduced and internally-threaded neck 6, the reduced portion of'the neck forming an internal shoulder 7.
Arranged longitudinally in the burner-tube is a horizontal partition consisting of a flat plate 8, which is approximately equal in width to the interior diameter of the burner-tube and extends from end to end of the latter. In the opposite edges of the plate 8 are formed a plurality of notches or apertures 9, while one end of said plate is rounded and bent up at a right angle to form a semicircular flange 10, which overlaps the end of the burner-tube and partially closes the latter or that part of the tube above the partition-plate 8. Upon screwing the nipple 5 over the end of the burner-tube, after the partition or plate has been inserted therein, the shoulder 7 bears against the flange 10 and clamps it against the end of the tube, .thus firmly holding the partition or plate in place.
In practice the burner is arranged horizontally in the combustion-chamber of the stove or heater and the threaded neck 6 of the nipple 5 is screwed over the end of the gas-supply pipe. The gas enters the lower half of the burner-tube, being prevented from entering the upper half by the semicircular flange 10, and flows under the partition or plate 8 and up through the notches or apertures 9 into the upper half of the tube and escapes from the latter through the perforations 3 in the form of jets, at which point the gas is ignited. The partition operates to break the force of the incoming flow of gas and check it slightly, causing the gas to come into intimate contact with the burner-tube, which being heated prepares the gas for instantignition and thorough combustion. The gas flowing into the upper half of the burnerpipe through the notches or recesses in the partition expands and escapes in jets through the perforations 3, and the direct force of the flow having been somewhat checked by the partition, as before stated, the ignitedjets burn close to the burner-tube, causing the heat to be equally distributed in the combustion-chamber of the stove or heater, instead of being dissipated in isolated points directly above against the stove top or lids.
Where natural gas is the fuel employed and is taken direct from the wells, oil or gasolene is sometimes carried with the gas into the pipes, and in the burners commonly employed the oil or gasolene comes directly in contact with the fire as it comes into the burner with the full force of the gas, resulting in an explosion. In my improved burner the plate breaks the force of the gas, and the oil or gasolene being the heaviest it settles and remains in the bottom of the burner until it is converted into gas. The chamber also serves as a trap to catch any water that may be deposited by the gas and prevent it from extinguishing the flame and permit the gas to escape.
An important feature of my invention resides in the small cost at which the burner may be produced and the readiness with which the parts may be assembled and taken apart. The burner-tube may be very conveniently and successfully formed from a section of gas-pipe, and both the cap and nipple are articles of ordinary manufacture readily procured at very small cost, the only part requiring to be especially made for the purpose being the plate or partition, which, owing to its nature, may be stamped out at a cost even proportionately less than the other parts of the burner. To assemble the parts, it is only necessary to insert the partition in the burner-tube and screw on the cap and nipple, and to thoroughly clean out the burner it is only necessary to unscrew the burnertube from the nipple and remove the partition.
Having thus described my invention, what I claim is 1. In a gas-burner, the combination with a burner-tube closed at one end and provided upon one side with jet-openings, of a plate inserted longitudinally in said burner-tube and forming a partition between the perforate and imperforate portions of said tube, said plate being provided upon its opposite edges with a plurality of notches or apertures, the opposite end of the burner-tube being closed between its perforated side and the end of the partition and open between its imperforate side and said partition to form a gasinlet, and a nipple screwed upon the burnertube and retaining the partition therein, substantially as described.
2. In a gas-burner, the combination with a burner-tube closed at one end and open at its other end and provided upon one side with jet-openings, of a plate arranged longitudinally in said tube and forming a partition between its perforate and imperforate sides, said plate being provided on its opposite edges with a plurality of notches or apertures and provided at one end with an upturned flange arranged to partially close the open end of the tube, and a nipple at the open end of the tube for connecting with a gassupply pipe, substantially as described.
3. In a gas-burner, the combination with a burner-tube closed at one end and open at its other end and provided on one side with jetopenings, of a plate arranged longitudinally in said tube and forming a partition between its perforate and imperforate sides, said plate being provided at its opposite edges with notches or apertures and provided at one end with an upturned semicircular flan ge overlapping the end of the burner-tube, and a nipple threaded over the open end of the burner-tube and provided with an internal shoulder arranged to clamp said flange againstthe end of the burner-tube, said nipple constructed to connect with a gas-supply pipe, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. I
MARVIN K. NEWTON.
