MULTIPLE UNIT MouNrIn'GroR ens BURNERs Application filed November 10,1930. Serial naesassa' This invention relates to gas burner constructions, especially the type provided for burning liquid gas and they object of this invention is tovprovide a multiple unit mounting for the gas burners in which the burners,

mixing chambers and drier tubes are rigidly anchored together in accurate predetermined spaced relation to each other and firmly supported in this position at the top of the gas range or utility.

Another object of this invention is to so construct the multiple unit mounting of the gas burners that the manifold consisting of an assembly of operating valves of the burners need no support on the frame of the gas range but are rigidly held in place by the anchoring means of the burners. c

Other objects and attendant advantages of the invention will be apparent from the e detailed description of one embodiment of the invention, reference being had to the accompanying drawing in Which Figure 1 1s a top plan view of the multiple unit mounting of the gas burners.

Figure 2 is a detail end elevation of one of the gas burners and section 011 the line 22 of Figure 1.

Figure 3 is an enlarged sectional view of a portion of one of the burners and the drying \1 tube located along side of it, the section being taken on the line 33 of Figure 1.

In the figures of the drawing like reference numerals indicate like parts.

The multiple unit mounting for gas burnl i ers forming the subject matter of my pres ent invention serves to simplify the installation of these burners in the gas range and keeps the burners, mixing chambers and dri ers in the proper spaced relation and in perfeet alignment so that these parts cannot get out of adjustment or alignment after they have once been installed.

The multiple gas burner and valve assembly unit illustrated in Figure 1 comprises w; four open burners 1, 2, 3 and 4 and one oven burner o. The open burners comprise hollow radial arms which radiate from a" common hollow center and have the burner openings provided in the top thereof. Leading into the back of each of the open burners between two of theradialarms thereof is a horizontal U shaped chamber ('3 which serves as the mixing chamber for the burner. The end of a drier tube 7 projects into the inlet of each of the mixing chambers to'direct the gas into the chamber and have it miX with the proper amount of air to provide a suitable combustible mixturewhich will produce a perfect heating flame when ignited above the burner holes. r

Each of the driers is provided with a valve body 8 in which is mounted the valve stem of the valve which regulates the flow of gas from the drier into the mixing chamber. A suitable valve handle 9 is mounted on the outside of each of the valve stems by means of which the valve stems are rotated.

As illustratedin Figure 1 a series of four of the valve bodies 8, 8 are connected in line with each other and are spaced to have the drier tubes project from them parallel to each other and in predetermined spaced re,- lation to each other. The spacing between the drier tube of a front burner and its rear burner, which is located directly behind it, is fixed by the combination spacing and supporting collars 10 and 11 provided on the front burner. These spacing and supporting collars are supported by the brackets 12 and 13 respectively which project from the ends of the hollow radial arms of the burner. tube 7 of the front burner passes thru the collar 10, and the drier tube '7 of the rear burner passes thru the collar 11,- and both of the driertubes are clamped in place in these collars by means of suitable set screws-14, 14E. Brackets 12, 13 and 16 are hollow and form extensionsof the burners and in the side of these hollow brackets are provided the burner holes 26 so that gas from the burner also provides a vaporizing flame which is directed against the portion of the drier located along side of the burner. v

The rear burner is providedwith but one combination spacing and supporting collar 15 on the end of the bracket 16 which projects from the rear burner to support the drier tube The drie 7 thereof in the'collar 15. -A set screw 14 clamps the drier tube'into the collar 15v and in a position in which the end of the drier tube projects centrally into the intake of the mixing chamber of the rear burner. In this way the drier tubes 7 of both the front and rear burner are anchored to the front burner while the drier tube for the rear burner is additionally anchored to the rear burner.

To support the front and rear burners and space them in fixed relation one behind the other, a combined supporting bracket and spacing bar 17 is provided. This spacing bar extends from one burner to the other and is suitably fastened to the bottom of each of the burners. A short extension of the spacing bars projects beyond the burners to the front and back of the frame of the gas range and these extensions are fastened to the frame to support the burners and driers, including the drier valves, in place in the frame.

, Two or more sets of front and rear burners are thus mounted on the gas range or tubing parallel to each other by means of two of the supporting and spacing bars 17, 17.

The gas from the tank is controlled by the master valve 18 which is suitably connected into the gas line so as to be supported in combination with the valves of the driers.

The oven burner 5 is provided with the mixing chamber 19 which is suitably connected thereto by means of the connecting duct 20. The gas is admitted into the mixing chamber thru the oven drier 21 which has its valve body connected to the valve body 8 of one of the driers by means of the connecting pipe 22. The oven burner, its mixing chamber and drier is mounted in the oven by me ans of the bracket which projects from the wall of the oven and is provided with a'pair of openings into which engage the ends of the lugs 24 and25 These lugs are provided on the oven burner and thus support one end thereof. The other end of the oven burner is supported by suitably fastening the connecting duct 20 to the wall of the oven thru which it passes from the mixing chamber 19 to the oven burher 5.

I claim: 7

1. In a multiple unit mounting for liquid gas burners in a gas range, the combination of a front and a rear gas burner, each having a vaporizing flame burner opening in the side thereof, a mixing chamber leading into each of said burners, a drier leading into each of said mixing chambers, combined connecting and supporting means for anchoring said burners, a drier leading into each of said mixing chambers, combined connecting and supporting means for anchoring said burners to the gas range and means provided on said burners for anchoring the drier thereto in fixed relation to the vaporizing flame opening of said burners.

2. In a multiple unit mounting for liquid gas burners in a gas range, the combination of a pair of burners, a drier leading to each of said burners, a connecting bar supported in the gas range, means for anchoring said burners to said connecting bar, clamping collars carried by said burners and means for rigidly clamping said driers into said clamping collars.

3. In a multiple unit mounting for liquid gas burners in a gas range, the combination of a fuel supply pipe, a pair of driers connected to said supply pipe and suitably spaced apart thereon, a pair of gas burners, a connecting bar supported in said gas range, means for rigidly mounting said burners on said connecting bar, combined guide and clamping collars provided on said burners, said collars being adapted to anchor said driers to said burners and hold them connected with said burners.

In testimony whereof I aflix my signature.

DON G. KELLEY.
