ATENT GAS-HEATER. 1

SPECIFICATION forming part of Letters Patent No. 7 6 0,535; dated MayQO, 1902.

Application filed April 11,1901. $811.1 Nq. 55,334 (Mu To all whom it mag concern.-

Be it known that IjEl wnR-n "AILMONJO, rea siding at Elizabeth,-ii1 the county of Union and State of New J ersey,*have invented certain new and useful Improvements in Gas- Heaters, of which the 'following' isa specifi cation, referencebeing had therein to theaccompanying drawings.

, This invention relates-to burners heaters.

The object of the invention is to produce a simple, easily-assembled, and cheap burner, which may be used singly or assembled in battery in stoves, ranges, fireplaces, and other heaters. The improvementlargely consists in the details of construction and combinations of elements;

Figure 1 is a vertical section or a burner complete. Fig; 2 is a bottom plan of the reticulated disk and holding-ring. Fig. '3 is a top plan of the deflector-plate, and Fig. 4 a side elevation thereof. Fig. 5 is a plan of the annular screen, and Fig. 6 a side elevation thereof. Fig- 7 is a side elevation of the burner-top with the deflector.15 alone.

In most gas-heaters it is common to furnish for gasa gas supply and an air-supply to a mixingchamber, in which the air and gas are mixed In my device the gas enbefore combustion. ters a central supplyetube=1=from any usual source of supply and thence; rises I into the interior of'the ynndem; Thiscylinder'2 is open at the bottom and extends slightly below the top of tube-1, so that the gas, which is lighter than air, will not escape under the;

bottomof cylinder 2.' Cylinder-2 is supported by legs 3, which maybe riveted to the out-- side of "the cylinder. These legs are turned out at their upperends andform brackets 4, I which-brackets support a second cylinder '5,-

the bottom of cylinder 5, and this all movesupward to the top of cylinder 5.

Cylinders2and. 5 simply short cylinders of I light pipeiof any suitable metal. A

:three-iuch-cylinder 5 makes an excellent burner.

At the top of cylinder 5I'p1ace a disk10 of wire-gauze. Thisdiskiisj simply cut from a sheet of gauze and is "of the'samediameter as the outside of cylinder 5. aeThefdis'k' 10 is merely laid on the top of the Lcylinder and held by -the inturned fiangezll 'of ring 12, which ring fits neatly arou'nd fth'e upper end of cylinder 5.

Gauze disk 10 forms the burnenproper and can be used without further addition. Above this disk the construction is according to the usage desired. For certain" purposes I prefer to use the defiector-plat'e l5alone. plate 15 .is preferably of sheet metal, of an extreme diameter equal to theouter diameter of ring 12. The plate I 15 1is'=a' disk with notches 16 in its edge, and has turned-down legs 17 a little insidetheouterLperiphery. These legs 17 are intended to rest on top of flange 11 and may Deformed to' lightlyclamp around ring 12. The'ri'singgas and air being ignited at the top of. burnerI -IO .will form a blaze whichcnrls aroundlthe 'edge of disk 15. The notches 16 give steadiness to the flame which it will not otherwise have. The top of the deflector l5 will be heated and may be used to snpporta'light cooking utensil. I prefer}: however; to use the burner with the reticulated auxiliary ring-burner 20 in addition to" the'defiector 15. This ringburner consistsof airing of wire-gauze of diameter less than:th e ring 12 and having short legs 21, whichsupport thering-burner alittleabove the topjof flange' lhsay one- At the bottom of outwardly until its outer edge is about in ine with t ou e of. Irina 12-. The d fieetor 15 is appliedabove :the ring-burner 20, legs 17 extending down'out'side said ring. The deflector 15 thus becomes .a cover for the reticulated ring-burner. When the gas is ignited at the auxiliary ring-burner] 20, a flame curls around the flange 22, and then draws inward toward the sides of ring 20, again curving outward when it encounters I do not know the reason for this course of the flame, but by ac- This tual test I have found the burner when so equipped to develop heat for heating an oven, &c., much quicker than when ring 20 is omitted. For some purposes, however, the ring-burner seems unnecessary. The outwardly-turned flange 22 of the ring-burn er seems to cause a much more complete combustion than when the same is omitted. The elevation of the lower edge of ring 20 above the top of flange 11 produces quite a diiferent combustion from that which would take place if ring 20 extended down to the flange 11, inasmuch as combustion in my construction begins inside the ring 20, and in part goes on just above the diaphragm 10.

As the various parts above the cylinder 2 are merely held together by gravity, the burner can be quickly assembled, broken, worn, or unsatisfactory parts replaced, or substituteparts of other form can be readily applied and all parts readily cleaned.

A battery of six or eight of these burners applied in the fire-box of a common coal stove or cookingrange enables the user to apply the device to all the uses of a cookingrange, with moderate expenditure for gas and with an efficiency for cooking, baking, broiling, &c., far in excess of the common coal-fire. A cook 40 enables the user to control the gassupply and to extinguish unnecessary bu rners when the burners are used in a battery.

\Vhat I claim is- 1. In a gas-heater, the combination ofan inflow gas-pipe, an open-bottom hollow cylinder surrounding the same, a removable cover on this cylinder having a central nozzle and side perforations, and a second open-bottom hollow cylinder, of larger diameter partly surrounding and extending above the first, and a reticulated-diaphragm burner at the top of this cylinder.

2. In agas-heater, the lower cylinder open at bottom and having supporting-legs, brackets extending outward from the sides of said cylinder, the upper larger cylinder removably supported on said brackets and surrounding the upper portion only of the lower cylinder, and a removable reticulated diaphragm and flanged ring fitting the top of said upper cylinder, substantially as described.

3. In a gas-heater, the combination of the cylindrical mixing chamber, a reticulated diaphragm at the top thereof and a flanged ring retaining the same, and a separatelyremovable metallic deflector-plate supported above said diaphragm by legs connected to the plate and resting on the flange-ring, substantially as described.

4. In a gas-heater, the combination of the cylindrical mixing-chamber, a reticulated diaphragm held by a removable flanged ring at the top thereof, an auxiliary reticulated ringburner above the diaphragm, with open gas-passage below, and a cover above said auxiliary ring-burner, substantially as described.

5. In a gas-heater, the combination of the mixing-chamber, a reticulated diaphragm at the top thereof, a ring-burner of reticulated material above said. diaphragm and having an outwardly-turned flange at its lower edge and a space below the same, and a cover for said ring-burner.

6. In a gas-heater as described, the combination with the mixing-chamber having a reticulated diaphragm at the top, of a ringburner of reticulated material supported above the diaphragm leavingaspacc between, a flange extending outwardly from the base of said ring-burner, and a cover for said ringburner, as set forth.

7. In a gasheater, the combination with the mixing-chamber having a reticulated diaphragm at the top, of a ring-burner of reticulated material and having legs by which the same may be removably supported from the chamber, leaving an open gas-passage below said ring, and a cover for said ring-burner.

8. In agas-heater, the combination with the mixing-chain her having a reticulated burner, of an auxiliary ring-burner of reticulated material supported above said diaphragm, and a separately-removable deflector-plate above said ring-burner. I

9. In combination with the mixing-chamber and reticulated diaphragm at the top, a separately-removable deflector-plate of sheet metal having notched edges and supportinglegs to rest on the top of said chamber.

In testimony whereof I affix my signature in presence of two witnesses.
