VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 556,355, dated March 1'7, 1896.

Application led March 24, 1893. Serial No. 467,46 7. (No model.)

To all whom t may concern:

Be it known that we, JOHN A. LANNERT and WILLIAM R. JEAvoNs, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners; and we do hereby declare that the following is a full, elear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention consists in a novel arrangement of the parts for initially heating the burner, and also in means whereby two or more burners are supplied from one vaporjet orifice, together with other novel features of construction and combination as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a vertical central elevation of the generator. Fig. 2 is a plan view of a section of the induction end of the mixing-chamber and shows the ducts or openings to supply air thereto. Fig. 3 is a plan view of astove embodying our improvenients and having the top broken away to disclose the burner mechanism beneath, as

hereinafter more fully described. Fig. 4is a section on line y2 2, Fig. 3, showing the closing and regulating plate over the burner in position to deflect vapor into the lighting-duct above the mixing-chamber. Fig. 5 is a crosssection on line 3 3, Fig. 3, showing the relation of the lighting-duet to the mixing-charnber and the depth and construction thereof.

In the drawings like letters of reference designate like parts in all the figures.

A is the supply-pipe for the oil or vapor, and forms a continuation of the supply-pipe from the oil-tank and serves alike for all the burners. A duct a a from the upper part of the supply-pipe communicates with the valve or needle oriiice a', which is controlled by the valve a2 having a stem convenient for the operator.

C is a chamber in which the vapor and entrained air are thoroughly mixed, and is designated as the mixing or eommingling chamber.

D is a duet from the bottom of the mixingchamber to a receptacle E formed about the base of the upright supply-pipe A and serves,

when initially starting the burner, to conduct the gasoline escaping from orifice a to the said receptacle E. This receptacle E is in the form of a deep circular trough or its equivalent and extends around the base of the upright supply-pipe A.

F is a valve controlling an oriiice f at the upper end of the duct f, which communi- Gates below with the supply-pipe at its lower end and serves to discharge gasoline or oil into the receptacle Il. The trough or receptacle Eis iilled with some absorbent material, such as asbestos or the like, and both the duct D and valve-orifice f are in position to discharge near the top of the troughE and a little below the surface of said absorbent material, for reasons hereinafter described.

A perforated tube G is seated on the sides of trough or receptacle E and extends upward and surrounds the pipe A at some distance from it to leave a name-space between it and the said pipe A.

The mixing-chamber C extends across to all the burners, and at the top thereof are flanged openings c c c. In these openings are perforated burner-plates c', which seat in the openings a little below the outer iiange c2, as shown in Fig. 4. A hat plate H is pivoted at one side of the burner and lies iiat upon the flange c2, thus effectually closing the burneropening c. By sliding the said plate laterally more or less an opening of greater orless size is made for the escape of gas from the chamber C.

A duct, gutter or channel I extends from one burner-opening to another over the mixing-chamber C, as shown in Fig. 5. This channel or duet serves as a path for vapor to travel in andignite one burner from another, thus facilitating the transfer of ignited vapor from one burner to another.

The plate H is formed with a groove or hollow h on its bottom at one side, so that when the said plate is moved to uncover a portion of the opening c, as shown in Fig. 4, the opposite side of the plate overlaps and directs gas into the channel, which, by reason of its gravity, flows along the channel to the next burner-opening.

J J are small perforations through which gas escapes in jets when the burner is in operation and burns about the generator op- ICO posite the openings to maintain the burner at a vaporizing condition. Y

In operation, the burner-opening c nearest the generator being opened by sliding away the covering-plate II ,the valve a is opened and gasoline escapes from jetbrifice a through the induction-tube B into chamber C, the walls of which chamber are so constructed as to conduct the gasoline to duct D, whence it runs to the absorbent material in initial starting-trough E. A lighted match or taper is applied to or through a suitable lighting-hole near the base of the perforated tube G about pipe A, and by reason of the vapor evolved from the light hydrocarbon thus introduced the flame will be immediately communicated to the gasoline at the surface of the absorbent material in trough E, and ignition instantly follows. A blue flame will then fill the chamber formed by the perforated tube G and heat the ducts a a and upper part of the sup ply-pipe. These parts quickly attain to a vaporizing condition, and vapor then issues from the orifice a', and, passing through the inducting-tube B, entrains air in the usual manner. The vapor and air thoroughly mixing in said chamber C escapes at the unobstructed burner-opening near the generator in a commingled state, but for convenience of this description and claims will be spoken of as vapor, and is ignited by the iire from the perforated tube, which remains burning until all the gasoline that is drained into the absorbent is consumed. lVhen it is desired to ignite t-he gas at the next burner the cover II to that burner is opened a little way, as shown in Fig. 3. This places the hollow portion of the cover in such relation as to direct some of the escaping gas into the duct or gutter I toward the ignited burner. rlhe gas being heavier than air it will travel by gravity in the channel to the ignited burner, and flame will flash over and pass through the narrow space between the cover and the burnerplate and will be communicated to the escap ing gas at the other side of the plate. The space between the perforated burner-plate and the regulating-cover II will admit of flame communication but is too small to admit of continued combustion therein.

By reason of the absorbent material in the trough E soaking and holding the gasoline from the sides of the trough the combustion is more gradual and does not increase to an annoying extent as the walls of the trough become hot. Again, by having the gasoline discharge into the trough near its top the gasoline is quickly manifested at the surface of the absorbent and consequently is ready for ignition at once.

The valve F may be opened to produce and l maintain a small iire to keep the vaporizing portions in a heated condition over periods in which the operation of the burner is not desired, and in this way the burner may be kept ready for full operation at any time. If desired, the burner may be initially heated as well as maintained in a heated condition by means of this valve by simply opening the valve to a desired point and igniting the asbestos.

The manner of conducting air to the induction-tube B by the lateral duets l) D protects the gasoline or vapor escaping from valve-orifice a from the flame that issues from the tube G, and some such protection might be considered an essential to this form of burner.

The burner-plate herein referred to may have any suitable shape or form, whether it be as here shown or in the form of a cone or any other equivalent construction.

The plate or cover II opera-tes practically as a valve to control flow of vapor from a burner to the duct I, and is so considered and referred to herein. The flame area of the burner also is controlled by said cover or valve,as the cover may be more or less opened, as preferred.
