Application October 1, 1946, Serial No. 7 00,422

3 Claims.

This invention relates to burner heads adapted for gas or oil burning devices, and particularly to those burner heads which are of the adjustable character.

The primary object of the invention is to provide a device of this character wherein it will be possible to produce, in one burner head, effective combustion of any type of gas used, without the necessity of aflixing different burner heads to adapt the burner for use in burning different types of gases, such as natural or manufactured gas.

Another important object of the invention is to provide a device wherein a necessary regulation or adjustment to produce effective combustion can be made in a minimum period of time, and without the requirement of special tools, and without the services of specially trained mechanics.

The above objects attain added importance from the fact that utility companies are often required to dispatch specially trained employees -for the purpose of installing diiferent burner heads, or making necessary adjustments in those burners already installed, when said companies are required to convert the burner from a burner of the type required for burning manufactured gas, to a burner for burning natural gas, or vice versa.

It is understood that the device, while primarily intended to accommodate varioustypes of gases as hereinbefore stated, is yet intended also to serve as a device wherein proper combustion of other fuels, in particular oil, can be effected.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Fig. l is a top plan view of the invention.

Fig. 2 is a sectional view thereof, taken approximately on line 2--2 of Fig. 1, looking in the direction of the arrows.

Referring to the drawing in detail, the invention embodies a hollow body portion 5 constructed in inverted frusto-conical form, the body portion being flared outwardly and upwardly from its base 6, and being open both at the base 6 and at I There is aflixed to the inner surface of the base 6 a supporting bar 9, which is upwardly inclined at its center and is formed with an opening intermediate its ends for receiving the adjusting bolt I G which is provided with a nut l5 for securing the deflector I l in its positions of adjustment. The lower ends of the bar 9 are secured to the base 6 by screws or similar securing means.

The device further embodies a deflector ll of bowl formation which is mounted within the body portion 5 for rotary adjustment, the upper edge of said deflector being flush with the upper edge or extremity l of the body portion 5. The deflector I l is adapted for rotary adjustment by use of the adjusting bolt Ill, which is capable of being turned as necessary to permit free rotary movement of the deflector.

The device further embodies cooperating means between the body portion 5 and the deflector ll providing openings or ports l4 through which is emitted the flame caused by combustion of the gases consumed within the burning device. This cooperating means includes spaced lugs on the deflector H and on the body portion 5, each lug having a straight and an inclined wall.

On the body portion 5 the lugs it! are disposed along the upper inner circumference thereof, and are extended horizontally inwardly toward the deflector II. On the deflector the lugs it are similarly disposed, except that they extend outwardly toward the body portion 5, the lugs l3 operating between the lugs l2.

It is to be noted that the lugs l2 and I3, when viewed in top plan, are of right-triangular shape, with the points of the lugs l3 contacting the annular upper edge of the body portion 5, and the points of the lugs l2 contacting the annular upper edge of the deflector ll, said upper edges being concentric and spaced apart. The lugs l2 and I3 are so arranged, in this connection, that one side of each lug, whether it be a lug IE or lug [3, extends substantially radially of said annular upper edges, while the other side surface of each lug is disposed chordally to said annular edges. The substantially radial side wall of each lug i2 is disposed opposite the corresponding side wall of an adjacent lug it, while the chordal side wall of each lug I2 is opposite the chordal side wall of an adjacent lug l3. As a result, when the chordal walls of adjacent lugs l2 and I3 are positioned in contact, the ports It will be of approximately rectangular shape and will be of minimum number, 16 in the present instance. When the radial side walls are in contact, the ports will still be of minimum number, but will now be formed as substantially diamond shaped parallelograms. When each lug I2 is spaced apart from the lugs It on either side thereof, the number of ports will be doubled, with rectangular ports alternating with ports of oblique parallelogram shape. The comparative sizes of these al ternating ports can be varied, of course, by selected location of lugs l2 relative to lugs is.

The arrangement is one specifically devised to provide a wide variety of adjustments for shaping of the flame at point of issuance thereof through the ports, whether natural gas, manufactured gas, or mixed gas be used.

As hereinbefore stated, the deflector H is adapted to rotate within the body portion to adjust the lugs of the body portion 5 and deflector H, with respect to each other. The opposing lugs i2 and is are adapted to be positioned in prescribed relation to each other and when positioned directly against each other, they forma minimum prescribed number of ports It. When they are positioned apart from each other, the number of ports it is doubled, the size of each port being dependent upon the distance the opposing lugs I2 and 53 are moved apart from each other.

The forming of the minimum number of ports It through positioning of opposing lugs l2 and I3 one against the other, provides proper openings for producing efiective combustion of natural gas. The doubling of the number or said ports 14 provides openings which are proper for producing eflfective combustion of mixed or menufactured gas, the size of the openings most desirable for combustion of the particular type of gas being capable of regulation in the manner hereinbefore described.

What is claimed is:

1. A burner head including a body portion and deflector connected for relative rotary adjust ment, the body portion having spaced inlet and outlet openings and the deflector being positioned across the outlet opening with its peripheral edge spaced from the outlet opening edge to deflne an annular space therebetween, an annular series of lugs on the body portion, and an annular series of lugs on the deflector, the lugs of both series each being of substantially right-triangular configuration when viewed in top plan, each lug having one side wall disposed substantially radially of said annular space and another side wall disposed chordally of said annular space, the substantially radial side walls of the lugs of the de flectors being disposed to contact the corresponding side walls of the body portion lugs, and the chordal side walls of the deflector lugs being disposed to contact the chordal side walls of the body portion lugs, the lugs of both series extending across the space to divide the space into an annular series of outlet ports, the lugs of one series adapted on selected adjustments of the'body portion and deflector to engage the lugs of the-other series to reduce the number of ports while in creasing the area of each port remaining, and to increase the number of ports while reducing the area or" each port, said lugs of both series, peripheral deflector edge, and outlet opening edge being all disposed in a horizontal plane common with the plane of the uppermost end of the burner head.
