GAS-BURNER.

SPECIFICATION forming part of Letters Patent N o. 58.6,748, dated July 20, 1897. Application tiled February 21. 1896.v Serial llo. 580,150. (No model.)

Kentucky, have invented a certain newand useful Improvement in Gas-l-urners, of which the following is a specification.

Myinvention relates to an improvement 1n burners for use in connection with either vvapor or coal gas, and more especially to the vapor-gas burner (having an incandescent mantle) for which United States Letters Patent No. 538,801 were issued to me May 7, 1895; and it consists in the novel features of construction hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, l `igure,1 is an elevation of my invention in its preferred foi-1n, showing the parts with the gas turned on full force andthe air cut off entirely from the mixing or mingling chamber; Fig. 2, a central sectional elevation of the same, but omitting the glass chimney and its supports, and also showing an independently-operatin g form of air cutoff; and Fig. 3, a broken scctienal plan on line a: of llig. l.

A represents the burner-barrel, having the usual spider Il forsupportingthe glass chimney C.

l) is a conical lVelsbach mantle supported over the burner-barrel by means of the customary standard or frame d.

a and a', respectively, -represent the usual cup and perforated diffuser-cap set on the top of the burner-barrel to lie within the encoinpassii'ig lower end or nieulh of the mantlc l). Y l) represents an ordinaryY gasstube i-'ornrin'g the arm of agas-lixture-such asa chandelier, or pendant, er a Wall-bracketthe end cap b' having the usual screw-threaded upturned nipple b2, which conveniently engages the internally-threaded lower end or mouth b of the burner-barrel.

c is a transverse slotebnstrueted in the burner-'barrel slightly. below the spider ll,

ande' is a sleeve or band sliding over saidl burner-barrel in connection with said slot c to control and regulate the entrance of atmospheric air therethrough.

E represents a disk or plug iitting rigidly within the buruenbarrel on a plane with the eral leakage,

bott-om of slot c and having an inwardly-ta-v pering orifice e, as best scenin `Fig.V 2.

F represents a hollow vertically sliding o1 reciprocating plug-iitting, free frein periphwithin the burner-barrel and having a conical needle-point valvef projecting upwardly therefrom to engage the ori'- ce e in the stationary disk E. 'lhe plug F is preferably bored centrally to form a inain gas-passage f part way up, and then small exit-holes or inclined branehesfz are made in its top, leading from the said central blo're to the space above in the burner-barrel.

d2 is a vertical slot in the burner-barrel through which projects a lateral pin or stud F, Whose innerend is set firmly in the plug F.

G represents a cross-bar or lever pivoted to an arm or lug g, constructed on the burnerloarrel adjacent the slot a2, and G' G are manipulatingchains attached to the outer ends vol said lever.

The outer end of stud F' en` gages a longitudinal slot or elongated opening g in lever G, whereby the latter is operatively coupled to the plug F. I prefer. to pro-A vide ya'n expansion spring-washer II on the pivot hof thc lever G, so that the latter shall be .properly held in the desired position for the' correspondingly .proper holding of the movable plug Il in relation to' the gas-orifice.

c within the burnenbarrcl.

I represents a link connecting the lever G with the valve-sleeve c', a lateral eye z'- being provided on the latter, to which the upper end of the link is loosely attached.' This link enables me to couple the air u ntrollingvalve sleeve with the gas eontrof .g needlevalve plug, so that they shall act simultaneously and yvhercby the proper proportions and adinixture of air and gas arevery readily aeeoxnplished and maintained at all tifnes. The construction shown in Fig. l and the con plin g of the air and gas controllers so that they shall act in harmony is provided for use in connection with vapor-gas, wheretlae quality thereof isvvariable; butl when coalgas" is used in the serviee-pipe with a practically constant or even pressure and quality there is very seldom any need of a supply of air through the side opening or slot e or any regnlating thereof, so that I operate thc gas controller valve and air-controller sleeve independently by dispensing with thelink and IOC simply setting the said controllersleeve to shut loil? the air from the opening c entirely,

as seen in Fig. 2,for arranging it anywhere else along or around the tube A iu connection tion at its top diffuser a.

with the said opening c to suit the'amount of air required, a set-screw J being used to secure it in position should theslccve be a ver ticall'y-operating one.

In the loperation of my burner, the lever being in the position shown in Fig. 1, the gas 'ilows in a full volume upward from the nipple into the sliding needle-base or hollow plug F; thence through the exit-holes f2' therein to and through the orifice ein thestationary disk E, where its volume i-s controlled by the needle-valve f; thence into the upper chamber of the burner barrel or tube for combus- If the gas is too rich and a supply of air is therefore necessary, the chain to the right, Fig. 1, is simply drawn down, thus raising the needle-point valve (diminishing the volume of gas?v and also simultaneously raising the valve-s eeve, vthe latter action permitting air to enter through the side opening c. in the burner-barrel immediately above the gas-orifice e, at.

which point they readily commingle, and the product passes upward to the 'combustion-cap at the' top, where the heat generated causes the mantle to become thoroughly incandescent and produce an intense and steady light for illumination.

It is very essential that the orifice' through which gas passes just before it enters the combustion-chamber should be clear and. free from any obstruction, so as to admit gas to pass therethrough with full force and thereby create a suction or siphoning of air. It 4will be readily seen that with my device Itcan readily clean said orifice should it become clogged. Another feature is, viz: The pres-r sure and quality even of artificiall gas are different indifferent cities and sometimes in the same city. Now it is very essential to have this opening exactly the proper size, so as'to admit the proper amount of gas required to ,heat the mantle to a point of incandescence.

1 When too much gas is used, it is not only a,

illuminating power is greatly decreased.

will be readily seen that these difficulties are waste of gas, but it also shortens the life of the mantle and diminishes its illuminating power. When the orifice admitsl too little gas, the It obviated through my device, as the gas-opening can be readily adj usted so as to' admit any desired quantity of gas.V and the open-bottom burners adapted to be attached to or screwed on any fixture. The features herein arc at once simple, readily adjusted, and operated.

I claim- 1. In a gas-burner, the combination, of an open-ended burnerbarrel, the 'side' ,of which is provided with a longitudinal and with a circumferential opening, a stationary oriiiceddisk' in the barrel between said openings, a

movable gas-oriiiced needle-pointed valvev within the barrel below the disk,a handle in the valve projecting through the longitudinal opening in the barrel, and a band around the barrel at the cirrmmterentialv opening, substantially as set forth.

.2.' Ages-burner composed of a burner barrel or tube having ,a valve-controlled ai r-inlet orifice therein; a stationary, gas-'orificed disk or plug mounted in said barrel adjacent the air-orifice; a movable, gas orilced needlepointedvalve arranged withineaid barrel below said ,disk and adapted to engage the gasorice therein; a ,manipulatingross-bar or .lever pivotally mounted on the burner-'barrelv and having 'an o ening therein enga ing a stud or -pin profecting laterally an out wardly, through an opening in the-said barrel, from the base of the needle-point valve;

'and a link-coupling between saidlever and the air-controlling valve;l the whole being constructed and adapted to operate so thaty the supply ot gas and air to the burner is properly controlled and com min gled,snbstan tially as. herein set forth.

' 8. A gas-burner composed of a burner-barrel having one or more air-orifices therein; .a vertically-'movable sleeve orband surrounding said barrel and controlling said air-orices, and having means'for securing it in -tho desired position; a gas-orificed plug or disk rigidly mounted in said barrel adjacent said air orifice orv orifices; a. gas-oriiieed needlepoint valve movabl y mounted within said barrel' below said stationary disk and adapted to JOSEPH s'rrnnns.
