STOVE.

Applieationfiled I/Iarch 1, 192%.

To: alliwhom' z'ltimwy1 concern:

Be it: known that I, ABRAHAM" LIBERMAN, a citizen of Poland, residing at Cleveland; inthe county of Cuyahoga and State of Ohio,- have tinvented new Y and useful lm provements in Stoves, of which the-tollowing is a=- specification.

My present invention pertains to safety appliances for stoves of the natural or manufactured gas-type and it contemplates the provision of means whereby it through neglect or otherwise the flame from the burner shou ldbe casually extinguished the gas willitravelto the chimney of the-stove and no-t ba'c'k up through the gas outlets into the room or apartment.

The invention further contemplatesthe provision of means in use in connectionwith.

Figure-3 is a view taken inthe planein-- dicated by the line 83 of Figure 2 and looking in the direction'ofthe arrows; I

Figure 4 is a View showing in detail the interior ring of the exterior burner ring and the vent from the ring.-

F igurefi isa sectional view taken in the plane indicated by the line 55 of Figure 3 and looking in the'direction of the arrows.

Figure 6 is a top plan view of one'o't my novel burner rings.

Similar numerals of referenced'esignate corresponding parts inall the views of the drawings.

For the purpose of illustration I show the stove 1 having the burner plate 2 on which the supports 3 for the burner rings rest, and I also show the ordinary inlet pipe 4 having the well known cocks 5 and an open door 6 as illustrated together with the Serial No.- 696 360 pipe-7 and gas-cock 8 for feed -of gas to the oven;

Arranged to" rest 011* the burner plate 2 immediately below the top ofthestoveand atv the I ordinary T well known position are my novel burner rings 9 that are by preference formed ofan upper and lower-semicircular portions" 10 and 11; I have" designated the ringsasfa whole by 9 and the portions that go to makeup theringbylO'and 11 forthe sake of clearness and these sections are bolted or otherwise secured" bv 1ne-ans of the fastenings '12. The upper portion 11 ispro" vided with the outlets 1 18 that are --arranged oii center for an importantpurpose herein after set forth and adapted 'to be-encased by the upper and lower portions-1O and- 11 of: the ring 9 is a circular conduit- 'l l-flthat is: provided with the nibsor-proje'ctions -15 that are conical shape as shown e and? are hollow throughout and the said nibs orprojee tions enter an apertureor opening in the conduit 14 and'at' the upper side thereof that in'turn registers withapertures in the burn er ring9.

It will be noted that I pro'videcteedpipes- 16 from the inlet pipe 5 to theburner rings and it will be noted further that at the rear of the burner ring are three more or less nibs 17 that take into a conical member 1.8 before passing to the outlet pipes 19. Particular attention isdireetedtothefa'ct' that I construct the pipes -16flan'd '19" so that gas to and from the burner rings-must; take" a tortuous course and this is do-nein order to assist in'bafliing the return of the gas to the burner after leaving the burner which will be clearly set forth inthe practical operation of the invention.

It will be further seen that-some oil the burners'are provided withoutlet pipes- 20 and these pipes are additionally bent'a's'; indicated by 21 soas to balhethe returirof ,QEIS;

The pipes 19 and 20. eventually terminate into and extend downwardlyalongthe rear of a stove and rest in a Qhinmey'QQth'at is provided at its lower 'endwith a'-seal- 23. This construction of s'eal'is duplicated in the oven portion of the chimney as indicated by 23 and is open to permit the gas from pipe 50 to travel directly into the conical portion 24, by means of opening 29' and arranged in the chimney 22 are conical shaped members 24: and 24: open throughout ONE-FIFTH TO JAKE their lengths as indicated by 25, 26', 27' and 28 and communicating one with the other and at its lower end a draught aperture 25 is arranged in the chimney. Mounted on the chimney 22 is a cap 26 that is arranged in the draught outlet 27 and has an upstanding tube 28 that terminates within the chimney 29.

The burners 9 may be constructed as illustrated in Figures 3 and i but I prefer that they be provided with the central curved portion 30 as in Figure 6. The purpose of the curving, twisting and bending of the pipes of this improvement is in order to baffie, as much as possible, the return of unburned gas.

In the practical operation of the device, gas enters the inlets 16 under pressure and goes into the interior 9 of the rings 9 and is sucked through the nibs 15 and out of conduit 14 into the registering burner openings 13. If, however, the light of the burners were accidently extinguished, the nibs being directed at the angle disclosed and staggered as shown would cause the-gas to travel within the ring at 9 until it reached the vent 18. The gas would then pass into the pipes 19 or 20 as the case may be and from there into the chamber surrounding the conical shaped portions 24 of the chamber or chimney 22. The gas will strike the seal 23 and will travel around the conical portion 24: until it reaches the upper end of the conical portion when it will be forced by air entering the lower end 25 of the chimney 22 into the tube 28 where it is carried off by the chimney 29. 1

In Figures 1 and 2 I have shown the oven as equipped with my novel burner and the construction of this burner and its appurtenances is similar to that of the burners above referred to and it will be noted that the take off pipe 50 is provided with a kink 51 and the operation of this burner is similar to that of the ones before set forth.

It will be manifest from the foregoing that if at any time through carelessness or otherwise the gas should become extinguished the liability of asphyxiation due to escaping gas is eliminated because of the fact that the gas cannotenter the room and pass through the openings 13 of the burners 9 if a burner is accidentally extinguished.

My invention is extremely simple in construction and arrangement and comprises no delicate parts such as will become inoperative after a short period of use and in the future practice of the invention I do not care to be restricted to the exact construction of elements as set forth and illustrated for the reason that I reservefi to myself the right to make such changes and modifications as fairly fall within the scope of the claims appended.

Having described my invention, what I claim and desire to secure by Letters Patent 1s:-

1. In means for the purpose set fort-h, the combination of a stove having a burner ring including a conduit; said ring having outlets therein, hollow nibs arranged in staggered relations within the conduit and having apertures that register with the outlets of the ring; said nibs being conical shaped in cross-section, a conical vent communicating with some of the nibs of the conduit, a chimney in direct communication with the vent and having a seal forming a chamber therein and also a draft passage whereby gas that enters the chamber will be forced by draft through the passage.

2. A gas burner ring comprising a conduit, a gas inlet, projections arranged within the conduit and in communication with outlets formed in the burner ring, a vent adapted to communicate with the interior of the burner, and means arranged in communication with the vent for precluding return of unburned gas to the burner ring.

3. In a safety appliance for gas burners, the combination of a burner ring having a conduit and outlets arranged therein, nibs secured on the ring, a vent communicating with the interior of the burner and exterior of the nibs, a conduit communicating with the vent and entering a chimney, a seal that provides a chamber in the chimney to con line the contents of the conduit and draft means for conducting the contents of the chamber into the draft pipe of a stove.

4. In a safety appliance for stoves and the like, the combination of a burner ring having outlets therein, a conduit in the burner, means for directing the flow of gas to the outlets to be ignited, said means being further adapted to prevent the flow of gas that is not ignited to the outlets and means for carrying off the unburned gas comprising a chimney having a seal that produces a chamber and means for conducting gas from the chamber.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
