BURNER FOR KITCHEN-RANGES.

Specification of Letters Patent.

Patented Oct 8, 1912.

Application filed July 10, .1911. Serial No. 637,629.

pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of the burner complete, and Fig. 2 is a bottom view thereof. Fig. 3 is a cross section of a range showing the burner as located in the bottom thereof, and Fig. 4 is a sectional elevation of the range lengthwise of the burner.

The present style of burner B is especially adapted for use in gas ranges which have been developed by me, such for example as shown in my co-pending application of even filing date-Serial number 637,630. The bottom 6 of the range is shown as having a draft flue 2 open from beneath the range into the oven 0, and the relative length of said flue is seen in Fig. 4, while the width and depth are shown in Fig. 3. These proportions are suggestive rather than arbitrary, but they show that while a portion of the burner comes directly over said flue an equally (large portion or half lies directly over the otherwise closed bottom 3 of the oven.

Now, the burner consists of the tube B,

a which may) be regarded as the burner proper and the ase or plate P is the support therefor and goes with it in this case as a graduating medium for the air draft or supply to the said burner. The burner itself has a row of jets or nipples 4 len hwise along each side and which are uni orm in all proportions. The plate or support P has two transversely curved sides 5 lengthwise which are spaced a art in two different widths and have troug shaped ends 6 in which .the burner is secured ateach end by a screw 7. All the space between the said sides and the ends 6 is open and the said jets or nipples extend across the said openmg and more or less overlap the said sides 5. The air to support combustion is derived through the fiue 2 from beneath and, obviously, the supply or uantity coming to the gasjets next over sai flue would be greater than that coming to the remainder of the burner if all the other conditions were equal. In fact in that case the air to the exposed jets would be excessive, while that to the other jets would probably be. insuflicient. Hence the present invention in which I construct the burner base P with two different widths of air spaces, the space 8 over flue 2 being narrower than the space 9 which is apart from said flue. The difference in width is clearly seen in Fig. 2, and is sucl as to compensate in the portion or half 9 for the greater exposure of space 8 to the draft.

.The air. is compelled to travel beneath said plate P and over the bottom 3 to the second section of jets but the larger outlet for the air in this section evens up the air supply and affords or provides even flames the full length of the burner. Gas is supplied to the burner by pipe connection with the elbgw 14 forming part of the burner at one en Owing to the size of the tube B it occurs sometimes that the gas does not light promptly from one row of jets to the other, and to overcome this tendency a transverse slot or saw cut a is made across the tube between oppositely disposed jets and through which a small portion of gas will issue and communicate the light from one side to the other,

A draft longitudinally along burner B is further induced by closing one end of the trough-shaped or curved plate P and leaving the other end 0 en for free discharge of air into the oven Thus, plate P has a cross flange 10 adapted to seat upon bottom 3, and it will be noted that this flange is at the end of the burner having the narrower space 8, whereas the open end of the platedesignated by 11--is adjacent wider space 9.

What I claim is:

1. A burner for ovens having nipples in rows along the sides thereof and a support therefor having narrow elongatedair discharge openings of different widths between its ends adjacent to said nipples, and said support being partially overlapped by said nipples.

2. A gas burner for oven ranges havin a row of laterally-projecting nipples provi ed with gas orifices, and a base plate for said burner having an air-distributing channel lengthwise thereof and an elongated airdischarge opening arranged parallel with and adjacent to said nipples and placed inwardly in respect to the discharge end of the gas orifices.

3. A gas burner for ranges comprising a tubular member having gas orifices longitudinally at the side thereof and provided with an air-distributing chamber open lengthwise of said burner beneath said orifices and closed at one end and open at the other to promote draft lengthwise of the burner.

4. A gas burner for oven ranges having a.

row of laterally projecting nipples along each side and a support for said burner having elongated air inlets beneath said nipples of different areas and co-extensive with said nipples.

5. A gas burner for ranges comprising a tubular gas-distributing member having side orifices, in combination with a- "troughshaped air-distributing member closed at one end and'open at the other end and prosupporting said burner having air discharge openings beneath the burner adjacent to and behind the discharge ends of the said gas jets.

In testimony whereof I afix my slgnature in presence of two witnesses.
