To all whom it may concern Be it known that 1, Jesse L. BRIGHT, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois',-have invented certain new and useful Improvements in Combined Gas and Coal Ranges, of which the following is a specification.

This invention relates to improvementsin combined gas and coal ranges where the gas burners are a permanent part of the range and may be used at will.

The invention has -for its object to provide a novel and improved gas burner for a range of the type stated, and which is somounted in the range that it can be readily placed in position for use, or swung out of the way when coal fuel is to be used in the range.

This object is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawings,

. in which Figurel is a plan view of an ordinary kitchen range or stove showing the application' of the invent-ion, the top of the stove being partly broken away; Figs. 2 and 3' are cross-sections of the gas burner in diferent positions; Fig. 4 isa longitudinal sec tion of the burner in the position shown in Fig. 2; Fig. 5 is an elevation of the burner invention is located in the flue 12 adjacent to that end of the wall 13 which is next to the fire pot-1G of the range.

,As shown in the drawings, the burner 15 is an elongated tubular body having two rows of perforations or flame apertures 17. The burner extends transversely of the flue 12 and has axially alined trunnions 18 and 19, respectively, atits ends, whereby it is rotatably mounted in the flue. The trunnion 18 is journaled in a bearing 20 mounted on the wall 13 near the back of the range,

and the trunnion 19 passes througha hearing opening 21 in the'front wall 22 of the Specification of Letters Patent. Patented Jaim e 15,- 1915. Application filed July 20. m. Serial No. 851.972 Y i i I range.- The trunnions turn freely in the bearings and they are also slidable therein for a purpose to, be presently described. The rear end of the burner tube 15 is closed, and its forward end is open, said open end being adapted to receire a pipe 23 leading from the usual air and gas mixing cap 24 In the top of the wall 13 is a pocket 25 in which the burner 15 is adapted to seat when it is not to be used, .said pocket being shaped to snugly accommodate the burner, as ,shown in lug. 3. From the wall 13, on one side of the pocket 24, extend upstanding pi'ns25 and to said wall, on the other side of the pocket, is hinged, as indicated at 26,21, com

hined shield and prop 27 for the burner.-

The burner 15 is substantially elliptical in cross-section, and when it is in position for use, it progects upward into the flue 12 with its major axis substantially vertical, in

which position it is held by the prop 27, the

latter engaging one side of the burner. The other side of the burner has-an outstandinglongitudinal flange or abutment 28 which seats on the pins 25 .Fig. 2 clearly shows the position of these parts when the burner is plaeedready for use. When the burner is not to be used, the prop 27 is swung-back slightly, clear of the burner, and the latter is allowed to swing down into the pocket 25,

theprop swinging back on thetop of the burner thus seating in the pocket... Fig. 3

shows the parts in this position. It will be noted that the prop covers the apertured portion of the burner tube and fits at its free end against the flange 28, which is riow on top. Thus, the flame apertures or perforations of 'the burner are shielded from ashes or soot while a coal or other solid fuel fire is used in therange.

Before the burner 15 can be swung intoi the pocket as hereinbefore described, it is necessary to move it inward in the direction of its length to disconnect its forward end from the pipe 23, which is done by-' pushing the trunnion l9 inward, said trunnion passing through the front wall 22 of the store and having a handle 29 at its outer end. Between the wall 22 and an abutment 30 on the'trunni'on, a spring 31 is coiled around the latter. The burner is shoved inwardagainst the tension of this spring, so

that when the burner is swung upward into alinement with the pipe 23, and the handle 29 is released, -the spring advances the burner so that the pipe 23 -enters its open bed end. The tension of ihe spring holds the burner andihe pipe coupled, and thus no leairage of gas is liable to occur.

The mixer 24 has the usual rotatable dish 32 for regulating she air supply. The gas valve 33 has a handle on the hack of which is lug 35. From she face of the dish 32 exiends a stem 86 which is in the path of the lug 35 and is intercepted 'llierehy shortly before the handle 3% has been "LIRRBCl so completely shut off the gas' A coniinue'd turning of the handle to complel e the shui, off of the gas, also turns the disk 32 to close the air supply to the mixer 2 the movement of the valve handle 3% being transmitted to the disk by the lug 35 and the stem 36, it

will be evident from the foregoing ihai no air can enter the range through the mixer 24 after the same is shut oil, which isdesirable when coal or other solid fuel is used in the range. If air were allowed to enter through the mixer, it would be cpl: to dis iiu'rb the circulation or reduce the draft.

The burner 15 is located directly beneath two lids 37 covering openings in thestove top 14-, so that upon removing these lids, she cooking utensils may be placed directly over the flames issuing from the burner; or the lids may be left on, in which evenl; the heel; from the burner will not only he local but will also circulate around the oven in the smoke flue 38 of the range is a damper 39 having a suitable operating device 420. This damper will be partly closed when the gas burner is in use. In the flue 3212 are also located two ordinary circular gas burners 41, provided with mixers and shul; ofi devices like the ones hereinbefore described. l

The gas supplyupipe of the l'iurinuers is shown at 42, the same being connected to the valves'of the burners in the ordinary man- .l claim:-
