Specification of Letters Patent.

Patented Sept. 18, 1906.

Application led August 26, 1905. Serial No. 275,878.

To a/ZZ ZIJ/wm it muy concern:

Be it known that I, WILLIAM SAMUEL PMM, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Gas-Burner, of which the following is a full, clear, and exact description.

The invention relates to that class of gasburners commercially known as incandescent arc lights or cluster burners, in which a number of burners using a VVelsbach mantle are grouped together to produce a .relatively intense light.

l The invention is applicable to both interior and exterior illumination.

The principal object of my invention is to provide means for increasing the illuminating power of the gas and rendering the combustion thereof more perfect than in burners now commonly used, to which end I provide a peculiar gas-heater arranged over the burners, from which heater the hot gas is conducted down to the mixing and burning devices.

It is also an obj ect of the invention to improve the devices for regulating and mixing the air and gas so that the Inost effective results may be obtained.

A further object is to c'onstruct the device so that by simple adjustment it may be converted into either an interior or exterior burner--that is to say, a burner adapted for use in or out of doors, as desired.

The invention involves various other features of maior or minor importance, all of Reference is had to the accompanying, drawings, which illustrate as an example the` preferred embodiment of my invention, in which drawings-'- Figure 1 is a perspective view showing the invention adapted for indoor illumination. Fig. 2 is an enlarged sectional view of one of the burners, as shown in Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a detail sectional view of the upper end of the mantle-sup ort showing the manner in which the removalile mantle-supports are arranged. Fig. 5 is a detail view of one ofthe mantlesupports. Fig. 6 is a sectional elevation showing the light adjusted for exterior or outof-door'illumination. Fig. 7 is an enlarged sectional view of the gas check or regulator shown in Fig. 6. Fig. 8 is a detail section on the line 8 8 of Fig. 6, and. Fig. 9 is a detail section on the line 9 9 of Fig. 7.

As best shown in Fig. 6, the gas is supplied to the burner from a tube 410, which extends into a heating-drum 11 and has a stop 12,

forcing the gas to pass out of the tube 10 through openings 14 in said tube and into the heating-drum. Below the stop 12 the tube is provided with openings 15, through which the gas renters the tube. Said drum 11 has tubes 16 passing through it, these tubes being intended to conduct the hot gases from the burner to the drum, thus thoroughly heating the gas therein. Below, the drum 11 the tube 10 supports a spider 17, which is adjustably fastened by setscrew 18. Said spider inturn sustains an annulus 19, 'with which the shade 20 of the lamp is engaged. The annulus 19 also supports the .chimney 21, which is tubular' in form and which rises from the annulus, wholly or partly inclosing the drum 11, so as to enforce the heated gases from the burner to passthrough, as contradistinguished from around, the drum. The gas supplied through the pipe 10 is therefore caused to circulate through the heatingdrum and thence back into the pipe 10, through which the gas passes downward to the burner proper.

According to the arrangement shown in Figs. 1 to 5 the tube 1() passes downward into Acommunication with a tube 22, which is fitted with a valve 23. Preferably this valve has a wheel or its equivalent 24 connected thereto, and to said wheel dependent chains 25 are joined, so as to permit opening or closing the valve 23 from below the gas-burner.

Said tube 22 extends upward into a gas- I chamber 26, which, as shown best in Fig. 8, is preferably of cruciform construction, though this is in no sense essential. The gaschamber 26 lies alongside of the tube 10 and is braced by means of a clamp 27, engaged with an ear 28, projecting from the gas-chamber. 29 indicates the usual pilot-frame tube which extends from the gas-pipe 22. Rising from the central part of the gas-chamber 26 and screwing into an orifice in the top thereof is a standard pipe or tube 80. Preferably this tube communicates with the interior of the gas-chamber, so as to increase the heating-surface thereof. At its upper end the tube 30 is provided with a head 31, (best shown in Fig. 4,) and is provided with a number of sockets 32. In these sockets the bent IOS ends 33a of the mantle-supporting arms 33 are loosely engaged. By this arrangement the mantle-supporting arms are removably yet securely held in place. Said arms project outward from the head 31 and carry the mantles 34, as shown in Fig. 1. The tubular part 30 is also important in that it prevents burning away by the heat of the llame.

According to the construction shown in Fig. 1 the burner adapted for exterior illumination is provided with four burners proper, all of the same construction and one of which is illustrated in detail in Fig. 2. Said burners proper comprise `a gas-tube 35, communieating with the gas-chamber 26 and formed at its upper end with an outlet-orifice 36, which is commanded by a needle-valve 37. The stem of the valve is threaded in the tube 35 and projects downwardly below the same. Said stem has a head 38, by means of which the valve may be adjusted, and preferably this head is formed with a kerf, facilitating the application of a screw-driver or similar tool. The tubes 35 are bent slightly in the form of an elbow, so as to facilitate the abovedescribed l-arrangement of the needle-valve 37. Fastened to the upper end of the tube 35 is a foraminous gage 39, which is cylin dric in form and loosely receives asimilar gage 40, attached to or forming part of the contracted burner-tube 41. Asis shown in Fig. 3, a setscrew 42 is provided to limit the relative j turning movement of the

parts

39 and 40,

and byadjusting the gage 40 the orifices in said gage and in the gage 39 may be placed wholly or partly in registry, so as to regulate the supply of atmospheric air drawn into the burner to be mixed with the gas entering the orifice 36. The contracted tube 41 'of the burner terminates in an enlarged part 43, over which the usual screen 44 is arranged. The mantle 34 hangs over the burner proper, as will be understood from the prior art and as is illustrated in the drawings.

The heated gas passing from the drum 11 downward through the tube 10 enters the gas-chamber 26 through the tube 22, the valve 23 being open for this purpose. Said gas is maintained in the chamber in a heated condition, the heat being kept up by the j uxtaposition'of the chamber to the burners and by the heating effect of the before-described tube 30. The check-valves 37 being properly adjusted the heated gas enters the burners through the orifices 36, it being well mixed with the atmosphere in proper proportions, according to the adjustment of the parts39 and 40, and the mixture passing through the contracted tube-41, after which it expands in the enlarged end 43 and is burned as it is emitted from the gauze cap 44, the heat of combustion raising the heat to incandescent and the-cluster'of burners giving off an intense light.

tion, as shown in Fig'. 6, is provided with iive burners instead of four, the fifth burner being Vsustained by the usual wires 45, which are fastened to the burners, as shown in Fig. 6. Figs. 6, 7, and 9 also illustrate a second inanner of constructing the device for regulating the air and gas supply to the burners. As shown best in Fig. 7, each burner has a connection 46 with the gas-chamber 26, and these communicate with two tubular standards 47. (See Fig. 9.) Said tubular standards 47 in turn communicate with a tube 48, in which a plug 49 is screwed. This plug is provided with an orifice 49a, which is commanded by a needle valve 50, and said valve has its stem threaded in the lower or bottom wall of the tube 48. Secured to the lower or exposed end of the stemv of the valve 50 is a thumb-wheel 51, which lies between the tube-standards 47, so that it may be conveniently grasped by the fingers of the operator. In this manner the thumb-wheel 51 of the valve is exposed and the gas is conducted around the sides thereof through the tubular standards 47. The gas is discharged through the orifice 49a into the burner, which is essentially the same as previously described.

It is pointed out that the gas and air regulating devices, shown, respectively, in Figs. 2 and 7, may be interchanged at will-that is to say, the device shown in Fig. 7 may be applied instead of the device shown in Fig. 1, and the device shown in Fig. v1 may be applied to the device shown in Fig. 7 instead of 4the mixing and regulating devices there illustrated.
