BURNER FOR lNCANDESCENT G AS-LlGHT 0H FOR HEATiNG'PURPOSES.

Specification of Lettere Patent.

Patented June 5, 196@ Original application liled Apri? i3, i904, defin No. 133,042. Divided and this application flied April 20. 1906. Serial Nn. 858.6%.

yTo JZ wharf it may concern:

Beit known that I, ISA/io Simon, a subjectV of the King of Great Britain and'reand, residing at 123Wardour street, London, Eng` land, have invented certain newand useful Improvements in Burners for Incandescent Gas-Lights or :forl Heating Purposes, of which the following is a. specification'.

This invention relates to improvements in burners for heating or lighting purposes, and when used for the iatter purpose more espe cieily to those employed for inverted incandescent `ges-iights, such as are described Ain my original application, (of which this is a divisional peut) Serial No. 203,042, filed Aprii 13,1904; i

A The invention consists in the special arparts hereinafter described. The invention wiii now be describedwith; :reference to the accompanying drawings, in whichf Y Figures 1, 2, 3, and 4 show sectional elevathe invention into eii'ect. Figs. 5 and 6 show the application of the invention to an oblique inverted' and to avertical lamp, re actively. Fig. 7 shows its appliceticn to a iowpipe, and Figs. 'S and 9 its application to heating purposes.

In can'ying the invention into Yeil-'eet according to one modication, as shown in Fig. 1, the'upper ende of ,the ,burner or Bunsen tube g isrconeshaped and any suitabe nurnwith ber of openings formed therein by pressing out the cut portions d. Projecting a short distance into the wider end of the cone is a fixed gas-sup lly nozzio f, which also carries a circular hood3 or bao r. The hood surrounds and supports theV mixing-cone a, as shown. y' is en Youter -inclosing spherical chamber, toward theiupperend of which a numberof air-inlet orices c are formed.

It will be seen from Fig. fthat the baiiie r is interposed between the Ytwo sets of inlet orices c and d and that its iower edge is some distance beiow them. It therefore follows that air entering at c does not directly mix with the geen but is iirst deiected downward into the quiescent ace b; where' it would be heated by the'p nots of combustion im@ pinging upon the exterior'of the chamber ifv e burner were being usedx in vculmination an inverted' gas-lamp. 1 By ineens of the injector-like action ofthe gas issuing from-the nozzle j the airis quietly andsteadiiy drawn ci? from the ace b up into the interior of the baffle rand t ence into the cone either at its open end or three h the'. side openins d. Itwill be understoo that the strengt of the injector action wili depend upon the distance the nosziej extends into the mixin c0I 1e. Further, the burning of the lamp wil be unaffected bystrong crosscurrents of air, since after entering at one sideV they *siii he deflected round the baie r and out through the openings c et the other side ofthe spherical chamber, Referrn' to F` 2, a siiniiar constructie nto that in Iiig. 1 1s shown, the sha e of the baiiie e in this case being spherica with a ynumber of air-inlet openings e formed towerd its lower end. Y 1

Fig. 3 shows a similar arrangement of mixing-cone and nozzle, the sha eef the outer Y incosin chamber being rnodiiied andthe inside bae Ybeing omitted. The outerlohambei* VjY is of approximately heniispherical shape provided at its upper end with a number ofeininlet orifices c5 adapted to register more or less with a simiiar number of oriices in an air-regulator plate k, adjustable Vby means of a projectin pin lc. The lower edge of the outer cham er is adapted to make Y contact with s radielly-corrugated closingplate l, the corru ations causing a number of small holes l to is formed around its lower end for the purpose of relieving any excess pressure Within the chambery'. v The cone is yin this case carried from a boss which is screwed upon .the fixed` ges-nozzie 4 shows a modified arra ement of' mixmg-eone and gas-nozz1e in w 'ch a decreased velocity is imparted to the ges and air mixture as compared with the arra ements shown in the previous figures. lr)Ighe -cone a, constructed as already de scrib is anged and secured to the interior surface of the spherical chamberj toward the .upper end o the latter in the manner shown, so that the cene expands outwardly and then inwardlyet it supper end, where an opening is left, 1n the center of which the j nozzle f is disposed. To su ply air to the open end of the cone, an auxilio. chamber 'n is mounted above the chamber Lin which anumber of air-iniet holes c' are formed, a reguator i: being added t9 control the amount 'of ithough no baille is shown between the mim -eone and the inclosing chambery',

such may e used, if desired.

'-In Figs. 3 and 4 an inverted mantle-sup- IOS IIO

port is also shown, the tWo figures showing ront and side elevations, respectively, of the saine form of mantlesupport, while the ulpper part shows different modifications of t ie mixing-conc and gas-nozzle` The mantlering is formed with projections which rest in hooks s, formed on the ends o the wires m, suspended from the ad justin -sleeve it, which is secured to the burner-tribe g by a setscrew.

In Fig. 5 the invention is shown as applied to an inverted incandescent gas-lamp arranged to project from a wall or bracket or from a flexible pipe in an oblique manner. The fittings may be either of the types before described.

Fig. 6 shows an adaptation to an incandescent gas-lamp ofthe usual erect type. In this case the use of the special mantle-su port above described is dispensed with, on y the spherical air-chamber with its other irnmediate fittings being used.

It will be understood that when the burner is not employed for lighting purposes the mantle attachments are not required and any suitable nozzle or head may be used on the burner-tube g, or the latter alone may sullice.

As shown in F ig. 7, the spherical air-cheniber ma be applied to a gas-blowpipe. Gas is sup ied by the iiexible or other pipe u to the sp ierical air-chamber made in any' of the forms above described. A handle portion o is added, while the mantle and its supports are replaced by a' flame de'lector or spreader iw. No compressed-air pi eis shown. 1t may, however, be led to the 1 aine in any suitab e manner.

Figs. S and 9 show the adaptation to a gas cookmg-stove, the views being an elevation and plan, res eetively. Beneath a tripod or other snitablg stand a: are disposed one or more heating-burners supplied with gas from the common supply-pipe u. The burners are each fitted with a spherical air and mixing chamber of any of the types above described. The top of the stand is fitted with the usual loose cover-plates y, one over each burner, one plate in Fig. l) being removed to show the burner beneath.

`When ern )loyed forlighting, other forms of mantle-holder may be used than those doscribed. I

Any suitable form of by-pass may be used.

Having thus described Iny invention, what l claim as new, and desire to secure by Letters Patent, is-` 1. A gasburner comlprising a perforated mixing-cone open at its erger end, a tube extending froln one end thereof, a gas-sup )ly nozzle projecting into its other end, and a perforated casing surrounding the cone substantially as described.

2. A gas-burner com rising a perforatingl mixing-cone open at its erger end, a tube extending froin one end thereof, a gas-supply nozzle projecting into its other end, a per- -forated casing surrounding the cone, and a baflie-plate interposed between the perforations 1n the inixingwone and those in the outer surrounding casing, substantially as described.

3. A gas-burner comprising a erforated inixin -cone a open at its larger en a tube exten ing frorn'one end thereof, a gaasupplgy nozzle f projecting into its other end. a conical hoo or baffle-plate r surrounding and supporting the mixing-cone, and a perforated sp ierical outer casing, j, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.
