GAS-BURNER.

Specification of Letters Patent.

Application iled September 12, 1917. Serial No. 190,882.'

To all 'whom t may concem.'

Be it known that I, WILLIAM JOHN BAR- BER a citizen of the United States, residing at leveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention pertains to improvements in gas burners for heatin furnaces, and the invention consists in a urner constructed and adapted to operate substantially as shownand described and particularly pointed out in the claims.

In the accompanying drawings Figure l is a side sectional elevation of a furnace on line 1-1, Fig. 2, with my new style of Fig. 2 is a front eleburner therein,

vation of the furnace and the and the with the ash pit door removed furnace broken away at the top.

Fig. 3, Sheet 2, is a plan view on line Fig. 2, above Fig. 4 1s an enlarged partially sectioned elevation of a portion of the burner, and Fig. 5 is a cross section on line 5--5, Fig. 4, showing the inclination of the jet orifices for the gas and the top of lpilot lighting tube, which is central between the burner units.

Simplicity, cheapness and efficiency vare the keywords to the resent invention.`

Y For example, all ot er burners with which I am familiar and employed for domestic or other heating furnaces', ranges and the `like with some sort'o air mixer, but the resent burner does not contain a mixer o any sort and depends on the original discovery 4that and a better heattu es which have opposite gas jets adapted to discharge the gas inward toward each in ,which the jets are so arranged that the gas streams therefrom meet at the natural point of combustion in the open air, say at a out the angle in Fig. 5. That is,

. the as issuing from said jets -under what may e regarded as normal pressure will comnatural combustion burn at the that mingle with air at the distance from the pipes and meeting angle described, or at about point.

This juncture of the gas streams from the o posite side jets naturally sets up a mixture with the air peculiar to itself by the fact of oonuence, and I have found that such mixthe grate-bars and burner.A

I ture or admixture not only produces what maybe termed perfect combustion but consequent economy in the volume of gas consumed and total absence of carbon deposits in the furnace. Furthermore, I can obtain combustion and the best of heating efec'ts from a lower pressure of gas than from any other burner that has come under my observation. l

Now, referring specifically to the construction of the burner, 2 represents the gas supply pipe with which each individual burner Patented May 2S, MMS.

unit 3 is connected by va pipe 4 ,of its own I and which comprises a vertical pipe joint or section 5. .The said burner units each consistv in this instance of a tube or pipe bent toapproximately U-shape, and there are four such units as shown and disposed at rigbht angles to each other in the furnace, `su stantially as seen in plan, Fig. 3. The said burnerzunits also are shown as positioned above or over the grate bars b and the vertical pipe sections 5 extend between the said bars and above the same as shown. he sides of the said burner units between their ends are parallel and spaced apart ata predetermined distance so that the issuing from the opposite inward y inclined jets orV orifices 6 will flow to a common meetin ypoint and burn midway between said si esand above the same as. indicated in Fig. 5, or approximately: as therein suggested by the arrows,

t0 the gas pressures. A. plurality of gas jets in sets oppositely are provided in each burner unit, say three or more in each, for furnaces of average size.

Each burner unit has its own valve v and valve control, and I preferably employ a controlling mechanism adapted to operate the valves from the living rooms in upper floors, a dial which has Iigures 1, 2,53 and 4 `on its face, tells the number .of units in service. or finger 13 points to any given ligure it tells -that that number of units are open, and to control the same I provide each valve with a toothed sector or segment 8 which is adapted to beturnedindependently and also t0v be placed in working engagement with a horizontal slidable sprocket chain 9, or its e uivalent, having a suitable support and w 'ch has a cable -10 attached to its end and stretched over ed with the rotatable finger or indicator iig If the indicator.

as stream v sus` a artments or` l sheaves 12 'ando'peratively ensegments may be operatively engaged with the said chain or rack-bar to open and close the valve or valves at will.

An upright pilot lighting burner 15 is showncentrally in respect to the several burners 3 and provided with jet openings for gas from which to light the burner units. The said pilot may be permitted to burn at all times through the season when heat is re- `a heating furnace, but it can be more or less variously used in grates, floor heaters and the like and is not therefore to be regarded y as limited to heating furnaces in its adaptation or use, and the arrangement of the burner units may be changed without departing from the invention.

ln operation the matter of normal or maximum gas pressure should be considered, and the jet orifices are made larger or smaller accordingly. For example, when `the pressure is several ounces the orifices should be about a thirty-second of an inch, and higher pressures will require correspondingly larger orificesl or holes. But once having the orifices suited to the normal y or maximum pressure, as in the case of natural gas, where pressures' run downin ex,- cessively cold weather, the burner is self accommodating to the lower pressures and requires no regulation by any means whatever. ln fact, all re lation by the valves is bad because it contrlbutes to imperfect combustion. Hence the proper method is to get the orifices of the right size to begin w1th and then open wide the valves and let the burnerk regulate itself, which it will. `'llhe valves therefore are really only for shut-od purposes, and the temperature in the room is governed by' using one or more heating units according to the amount of heat wanted. For this reason also the units are made separate and several are employed so -as to get the maximum and the minimum heating f effects at will.

What l claim is:

1. A gas burner unit consisting of a relatively small pipe bent back uponitself near its middle with 'a U bend and the sides thereof provided with opposite gas' jets inclined inwardly and upwardly atan angle of approximately forty-ve degrees to a vertical plane and one end of said unit open to make pipe connection therewith.

2. A gas burner unit consisting of a single piece of pipe bent substantially U-shape and having parallel sides providedwith oppositely disposed gas jets in their inner sides said jets spaced apart to approximately onefourth the length of the unit. c

3. A hot air furnace and a plurality of substantially U-shaped burner units disposed about a common center therein having opposite inwardly inclined gas jets along the inner and upper side portions of the sides of each unit and apilot lighting burner located in said center to ignite said units.
