GAS BURNER.

Application led February 24, 1925. Serial No. y11,103.

To all whom it may concern.' v

Be it known that I, ALEXANDER B. SHARP, a citizen of the United States, and a resident of Steubenville, in the county of Jefferson and State of Ohio, have'invented a new and useful Improvement in Gas Burners; and l do hereby declare the following to be a full, clear, and eXact description thereof.

My invention relates to gas burners, and particularly to burners having a plurality of burner tips or openings.

One object of my invention is. to provide means whereby each tip of a burner is supplied with the proper amount of fuel, and whereby the fuel so supplied is prevented. from becoming unduly heated before passing through the'burner grids or tips.

Another object of myinvention is to provide a burner grid possessing improve functional and structuralk characteristics.

Still another object of my invention is to simplify and improve generally the structure and. operation of gas burners'.

One form which my invention may take is shown in the accompanying drawing wherein Fig. 1 is a perspective view of a burner, constructed in accordance with my invention; Fig. 2 is a view, partially inf section, and partially in elevation, on an enlarged scale, of a portion of the burner of Fig. 1; Fig. 3 is a view taken on the line 3 3 of Fig. 2; Fig. 4 is a view of one of the holding members for the bars that enter into the construction of the burner grids; Fig. 5 is a perspective view .of one of said bars; Fig. 6 is a view showing the bars and holders as in Figs. 4 and 5, assembled into a unitary structure; Fig. 7 is a cross sectional view of the structure of Fig. 6, and Fig. 8 is a view similar to Fig. 3, but, showing the grid bars extended beyond the orifice walls.

The burner comprises an inlet 8 which may be of somewhat the usual form and a chamber 9 into which the inlet leads. The chamber 9 is provided with two channel eX- tensions 10 that are partially circular in with perforated extensions 13 by means of` which it may be mounted in a stove. In the case of a radiant heater, the radiants would be supported above the orifices 12. The chamber portions 10 gradually decrease in cross sectional area toward their outer ends so that the necessary pressure of fuel therein is maintained to effect even distribution of such fuel to thev various orifices. The chamber `portions 10 have concentric vanes preferably formed integrally therewith. These vanes may be of variousv forms, and serve to absorb heat from the fuel passing through the burner and to dissipate such heat by reason of their exposure to the outside air. Overheating of the burner is thereby prevented and consequent tendency toward backring reduced.

The vanes 14 increase in surface area tod ward the outer ends of the burner portions 10, as shown in Fig. 2. The desirability of this arrangement arises by reason of the fact that as the gas flows toward the orifices at the ends of the burners its temperature increases, and provision must therefore be made to effect a greater absorption of heat therefrom. j

The burner units 12 are composed ofy bars 'i 15 supported in crimped holders 16 preferably o f ductile metal. The manner in which the metal is crimped for the reception of bars is shown more clearly in Fig. 4. It will be seen that as the bars are all inserted from the bottom side of the member 16 their-upper and lower edges will be in proper horizontal alignment. That is, each bar will be in alignment with the adjacent bars. Also that the bends ofv the crimped member' at either side thereof are in alignment so that a .comparatively smooth surface results. Each bar is separated from the next bar by a double thickness of the strip material thus providing aifnple space between the bars for passage o as.

rfter the units have been assembled as shown in Fig. 6 they are driven into the rectangular opening 11 until they occupy the position lshown more clearly in Figs. 1 and 7. The holders 16 are disposed immediately above the edges 17 of the side walls of the chamber 9. so that they present no obstruction to the ow of gas through the openings. The units 12` are pre erably made of such thicknessthat they willkl be 'can readily be made and the body of the burner continued in use even vthough it becomes distorted through acticnof the heat and the like, because of the adaptability of the units to openings of various sizes andy contours. n

I claim as my invention:

1.l A gas burner comprising an elongated chamberA provided with a fuel inlet and with a plurality of openings, and burner grids adapted to bevmounted in said openings, each of said grids comprisin a unit composed of bars and holding str1 s that are of accordion or plaited form, t e bars being disposed between the folds of said strips.

2. A gas burner comprising an elongated chamber provided With a fuel inlet and with a plurality of openings, and burner grids adapted to be mounted in said openings, each of said grids lcomprisingfa unit composed of bars and holding strips that are of accordion or plaited form, the bars being disposed between the folds of said strips,

and grid vunits having close fitting engageof bars mounted edgewise andl disposed in side by side relation, and held in assembled position by strips bent upon themselves a plurality of times to form folds, each bar .lying within a fold.

' 4. A burner grid comprising a plurality of bars mounted edgewise and disposed in side by side relation, and held in assembled position by strips bent upon themselves a plurality of times to form folds, each bar lying within a fold and only alternate folds containing a bar, wherebyA each bar is separated from the adjacent bar by a double thickness of the strip material.

5. A burner comprising a plurality 'of bars mounted edgewise and disposed in sideby-side relation, and held in assembled position by strips bent upon themselves a pluralit of times to form folds, each bar lying within a fold and the strips being disposed intermediate the mid and end portions of the bars.

6. A burner comprising a plurality of bars mounted edgewise and disposed in side by side relation, and held in assembled position by strips bent upon themselves a plurality of times, each bar lying within a fold and the folds being so bent that the upper edges of the bars are in relative horizontal alignment.

In testimony whereof I, the sai-d ALEX- ANDER B. SHARP, have hereunto set my hand.

ALEXANDER B. SHARP.
