Application filed July 1, 1921. Serial No. 481,796.

To all whom t may concern:

Be it known that I, CARL I-I. Horrs'rE'r'rER, a citizen of the United States, residing at Erie, in the county; of Erie and 'tate of Pennsylvania, have invented new and useful the ollowing is a specification.

Vith stoves such as receive their supply of gas at the end of the burner and particularly sto-ves which use a radiant to which llame is delivered it is ditlicult to so introduce the gas as to get a uniform How from each group of jets. One of the purposes of this invention is to obviate this difficulty.

The invention is illustrated in the accompanying drawing as follows :e-

Fig. 1 shows a Jfront view of the stove, partly in section, on the line 1-1 in Fig. 2.

Fig. 2 a section on the line 2-2 in Fig. 1.

Fig. 3 al section on the line 3-3 in Fig. 1.

Fig. el a section on the line 4 4: in Fig. 1.

1 marks the base of the stove, 2 the sides and 3 the back on the stove. A burner 4: has the lugs la which extend to the back 3 and the burner is secured by screws 5 extending into the lugs 41a. The inlet end of the burner is provided with a mixer 6 and a supply valve 7 in the usual manner.

The burner has the burner chamber 8 from which lead the jet openings 9. These are formed with stools extending upwardly from the upper 4wall of the burner. Thimbles 10 are arranged over the stools 9 and these are provided with burner gauze tops 11 making ineffe'ct a group of jets extending from the top of the thimble. Tubular radiants 12 of heat-resisting material, scroll-formed, are arranged over the jet groups and extend upwardly above the burner.

The burner has ya depression 13 at its inlet end above which there is formed a baffle 14 extending from the inlet end and inclined toward the center. An upturned passage 15 extends from the depression 13 and a baffle 16 is arranged directly over the upturned pass-age 15.

With this construction the'incoming gas is in effect delivered at the center, is deected equally in both directions and thus feeds the groups of jets equally. The baille 16 prevents a direct How ofthe gas to the jets immediately above it.

In order toprevent the ready displacement of the radiants 12 a lip la may be provided along the burner in front oi' said radiants.

I form a simple backing 17 for the radiants by utilizing an asbestos board, bending the edges as shown atthe ends and arranging the edges along the plates 18 forming delecting sides of the stove front. In this way the board not only forms a backing but also protects the sides from the immediate action of the incandescent radiants. The board is spaced from the metal back 3 so as to insulate this back romthel heat of the radiants,

JVhat I claim as new is 1. A burner having a burner chamber, the chamber having a mixture inlet passage at one end extendingfrom the burner and in alinement therewith; and a baiiie over the inlet end extending into the chamber forming an upturned passage intermediate the ends of the chamber.

2. A burner having a b-urner chamber, the chamber having an inlet passagey at one end; and a baille over 'the inlet end extending into the chamber forming an upturned passage intermediate the ends of the chamber,

said baille having a downward inclination toward the center.

3. A burner having a burner chamber, the

chamber having a depression at oneend in extension of a mixture inlet passage; and a baille extending from thejinlet end over the depression forming an upturned passage intermediate the ends.

4. A burner having a burner chamber, the chamber having a depression at one end in extension of a mixture inlet passage.; a baille' extending from the inlet end over the depression forming an upturned passage intermediate the ends; and a baiie over the upturned passage.

5. A burner having a burner chamber, the .l

chamber having a mixture inlet passa-ge at one end extending from the burner and in alinement therewith, and a baille over the inlet end extendinginto the chamber forming an upturned passage at the center of the burner delivering mixture equally to the ends of the burner.

In testimony whereof I have hereunto set my hand.

- CARL II. HOFFSTETTER.
