SPECIFICATION forming w of Letters Patent No.,'71 1,522, dated October 21, 1902. Application filed January 11 1902. Serial No. 89,304. (No model.)

T0 on whom it may concern.-

Be it known that I, LEROY S. PFOUTS, a citizen of the United States,'residing at Canton, I in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Incandescent Vapor-Burners; and I do h'erebydeclare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings,

making a part of this specification, and to the figures of reference marked thereon, in

which- Figure 1 is a side elevation showing parts in section. Fig. 2 is a top view showing the parts properly assembled and illustrating a portion'of the hood broken away. Fig. 3 is a horizontal sectional view showing the ventilating-tube and the supply-pipe and illustrating the different passages. Fig. 4 is a transverse section of the mixing-tube and a sectional view of the shut-01f valve. Fig. 5 is a longitudinal section of the vaporizingtubes and their clean-out needle, also showing portions of the feed-pipe and the mixingtube.

The present invention has relation to incandescent vapor-burners; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the draw- 1 ings.

In the accompanying drawings, 1' represents the tank, which in this instance is located below the burners and the different parts belonging thereto; but it will be unply-pipes extend upward in the positions illustrated in Fig. 1 and are connected at The sup-' their top or upperends to the flanges 3,which flanges are formed integral with the collars 4.. From the flanges 3, and the collars 4 extend the arms'5, which arms are each provided with the passages 6, which passages communicate with the passages 7, formed in the supply-pipe 2;

Directly below the arms 5 are located the arms 8, saidarms 5 and 8 being cast integral with each other, and the passages 9 each connect the passages 6 with the passages 10, said passages 10 being formed in the arms 8 and will extend throughthe vaporizing-tubes 11, said vaporizing-tubes being attached to the inner ends of the arms 8 in any convenient and well-known manner.

The vaporizing-tubes 11 are provided with the usual gas-tips 12. Each of the vaporizing-tubes 11 is provided with theclean-out needles 13, which clean-out needles may also be used as shut-off needles or valves. To the top of the tank 1, which top may consist of theseparate brazed piece 14, is securely attached in any convenient and well-known manner or formed integral therewith the post 15, to which post are'attached the elbows 16; but, if desired, the post 15 and the elbows 16 may be formed integral with each other, as well as the head 17. From the short head 17 1 extends the cylinder 18, which'cylinder is provided at its bottom or lower end with the flange 19, which flange is of the ordinary constrnction and is of course for the purpose of cient to allow the properadmixture of air with the gas, which gas and air is conveyed through the mixing-tubes to the elbows 16 and thence to the burners.

For the purpose of preventing any opposing pressure as between the two mixingtubes 22 the partition 23 is provided, which in this instance is the inner joined portions of the elbows 16; but it will be understood that the object above specified can be carried out with any kind of a partition that divides the bottom or lower portions of the mixingtubes 22.

The bottom or lower portion of the hood 24 may be of the form shown in the drawings, or it may be difierently formed, as the particular form of the lower portion of the hood has no reference to the operation of the burner proper. The upper part of the hood is provided with the annular flange 25, the bottom or lower portion of which annular flange is provided with the partition 26, which partition extends inward a short distance and is provided with a central opening to receive the tube 27, which tube 27 is extended upward above the tops of the vaporizing-tubes 11.

To the tube 27 is connected the upper tube 28, said tubes 28 and 27 being telescoped together and are held in proper relative position by frictional contact with each other. It will be understood that in order to properly telescope the tubes 27 and 28 and at the same time allow for the room taken up by the vaporizing-tubes 11 slots or cut-ont portions 29 must be provided. To the top or upper end of the tube 28 is connected the headdeflector 30, said head-deflector being of the usual construction and forms no particular part of the present invention.

For the purpose of providing a means for producing an atmospheric pressure an ordinary inlet air-valve 31 is provided, which valve is provided with the usual connectingnozzle 32.

It will be understood that the tank is to be provided with a filling-aperture and should be properly closed by means of the usual cap 33.

The band 25 is provided with suitable apertures through which the ends of the mixingtubes are passed, as illustrated in Fig. 1.

It will be understood that by providing the band 25 the same will act as a shield against any air-currents, and at the same time a chamher is formed between the band 25 and the tubes 27 and 28, by which arrangement the air is heated to a certain extent, thereby heating the air at the point where it is mixed with the gas, this object being very desirable in aiding combustion, as the heated air mixes much more readily with the vapor than cold air.

It will be understood that the arms 5 should be provided with the ordinary cut-off valves 34. It will be understood that the outer ends of the passages 9 should be closed by means of the screw or cap 35, inasmuch as said passages cannot be drilled, except from the outside, and of course must be closed.

It will be understood that by my peculiar construction I am enabled to generate from a single font a sufficient quantity of gas to supply a large burner or to supply a number of smaller burners, by which arrangement I am enabled to produce a much more brilliant light than is done in the ordinary Way.

The needles 13 are provided with screwthreaded portions and the outer ends thereof provided with knobs 13, which knobs are for the purpose of impartlng rotary motion to the needle or clean-out and at the same time giving to said needle a reciprocating movement.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. The combination of a tank, supply-pipes leading therefrom and communicating with lateral arms having passages, said passages leading to vaporizing-tubes, and the vaporizing-tubes extended in opposite directions over the main burner, mixing-tubes provided with open upper ends and the open upper ends located upon opposite sides of the main burner in a horizontal plane above the main burner and the vaporizing-pipes extended downward and communicating with a single chamber located directly below the main burner and a guide-shield or partition located below the single chamber of the main burner, substantially as and for the purpose specified.

2. The combination of a tank, feed-pipes leading therefrom and vaporizing-pipes provided with tips, said vaporizing-pipes located above the burner, telescopic tubes located above the main burner, and the vaporizingpipes extended diametrically through the telescopic tubes and side by side, and each of the vaporizing-pipes provided with gas-tips located upon the outside of the telescopic tubes, a hood provided with an annular flange, said flange provided with a partition, and the gas-tips of the vaporizing-pipes located between the flange and the telescopic tubes, mixing-tubes provided with open ends communicating with the chamber between the telescopic tubes and the hood-flange and a main-burner chamber having connected thereto the mixing tubes, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

LEROY S. PFOUTS. Witnesses:
