2 Claims. (01. 158-99) This invention relates to a new and improved gas burner., Y

Fuel gas burners such as are commonly used in gas ranges are fixed in position with respect to the range. It is the principal object of this invention to provide a burner that is adjustable both horizontally and vertically to attain a position that is most eihcient with respect to that particular range or to the utensil that is being heated.

It is a further object of the invention to provide a burner having a single discharge orifice, whereby the gas may be properly and completely burned.

Further objects will appear to those skilled in the art from a reading of the specification.

Th accompanying drawings illustrate a preferred embodiment of the invention. In these drawings:

Figure 1 is a side elevation, partially in section, of the new and improved burner as applied to a gas range.

igure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a longitudinal vertical section, on an enlarged scale, of the new and improved gas burner.

Figure 4 is a representation, on a reduced scale tion of the flame when a utensil is being heated.

The new and improved burner comprises a horizontal tube 10 open at one end it to receive the nipple i2 of a gas pipe l3. Th end H has a downwardly depending fiange M to aid in seating th tube to properly on the nipple I2. The other end of the tube I terminates in an upwardly extending diverging nozzle l6.

Depending from the tube ill, underneath the nozzle 16, is an internally threaded sleeve I 8, which is adapted to receive the threaded stud IQ of an adjusting screw 26. The adjusting screw 20 rests on a drip pan 22 or similar part of the gas range.

It will be apparent, therefore, that as the adjusting screw 23 is rotated in one direction or the other, the nozzle 1 will be raised or lowered with respect to the grate 24 on the top 'of the gas range. The movement of the gas burner II) will center about the seat 54 that rests on the nipple l2.

A ball-and-socket connection 26 is attached to the horizontal extremity of the nozzle 16 by means of a threaded cap 28, and a union 30 joins .is completely burned.

the connection 213 with a slotted rod 32. The slotted rod 32 accommodates a set screw 34 that is secured in a bracket 35 fixed to the stove or range. The head of the set screw 35 is spaced I from the bracket 35 to permit vertical movement lei the slotted rod 32, as indicated in Figure l of the drawings.

Consequently, rotation of the union 30 will adjust the burner it) horizontally, the slot in the slotted rod 32 permitting movement at one end, and the nipple l2 permittin movement at the other end. The adjusting screw Zil'is, of course, not secured-to the drip pan 22, and slides along the surface thereof as th burner I0 is adjusted horizontally.

In the operation of the device, operation of the adjusting screw 29 will vary the position of the orifice It with respect to the grate 24, the spacing of the head of the set screw 34 from the bracket 35 determining the extreme upper and lower limits of the vertical position of the orifice [6. Operation of the union 30 will vary the horizontal position of the orifice l6, as hereinbefore indi- I cated.

orifice 16, the combustion of the gas will produce a single concentrated flame, as illustrated in Figure 4 of the drawings. When a pot is on the grate 24, the flame will flow along the bottom of the pot and creep up the sides, as indicated in Figure 5. The lateral distribution of the flame under the pot will pr-ovideaccess to a greater quantity of air, to the end that all the fuel gas The horizontal and vertical adjustments hereinbefore described permit positioning of the orifice IE to obtain the most eificient combustion of the gas with respect to the particular utensil being heated. It is well known, of course, that the usual fuel burner does not permit any adjustment, so that the gas will be burned more or less completely, depending on the type of utensil being heated. This disadvantage is obviated by the new and improved burner herein set forth. It should also be mentioned that the quantity and pressure of gas are factors in determining the position of the orifice IS with respect to the utensil, it being an object of the invention to impinge the hottest portion of the flame against the bottom of the utensil.

A series of tests have demonstrated that the saving in gas consumption averages about onethird, and may approach one-half.

Where as the invention is shown as applied to a burner for fuel gas, it is apparent that it is equally applicable to other types of fluid fuels.

I claim:

1. A gas burner comprising a substantially horizontal tube having an open inlet end to receive a horizontal gas supply nipple, the opposite end of the tube being provided with a short upstanding tubular discharge nozzle, a depending extension secured to the bottom of the tube adjacent to the upstanding discharge nozzle and having a substantially vertical screw threaded opening, a substantially vertical adjusting screw engaging within the screw threaded opening and adapted to rest upon a fixed support and being adjustable to raise and lower the upstanding discharge nozzle, a stationary support arranged substantially at the elevation of the tube and} ceive a horizontal gas supply nipple, the tube be ing provided adjacent to its opposite end with an upstanding tubular discharge nozzle, a depending boss secured to the tube near its end having the upstanding discharge nozzle and having a substantially vertical screw threaded opening, a substantially vertical adjusting screw engaging within the screw threaded opening and adapted to rest upon a fixed horizontal support and turnable for raising and lowering the end of the tube having the upstanding discharge nozzle, a fixed support arranged substantially at the elevation of the tube and spaced beyond the end of the tube having the upstanding discharge nozzle, the tube being provided in its end having the upstanding discharge nozzle with a ball socket, a ball swivelly mounted within the ball socket, a tubular internally screw threaded sleeve secured to the ball and extending axially beyond the end of the tube having the upstanding discharge nozzle, a screw threaded rod engaging within the screw threaded sleeve and extending axially beyond the sleeve and toward the fixed support, the rod including a substantially flat head having a longitudinally extending adjusting slot formed therein, the head extending over and engaging upon the fixed support, and a screw extending through the slot of the head and adjustably connecting the head to the fixed support.
