. SPECIFICATION forming part of Letters Patent. No. 266,889, vdatedEQctober 31, 1882.

' Application filed September 19, 1882. (No model.) i

Be it known that I ELIAS zen ot' the United States, 'residing'at- Jersey City, Hudson county, 4I lew .Jcrsey, have in vented new and useful ImprvementsinGas- Burners,`of which the following is a'specilication.

The objectsof -this invent-ion areto insure strong upwardIy-induced'currentsof airaround the top of a gas-burner. and to deflect the said air-currents Vtoward the flame from all sides,V

so as to perfect combustion', also,to induce strong upward currents of air around the gasburnertip, sc as topromote combustion and intensify the heat, whereby a surface of p1ati. num presented to `the flame will be rendered highly incandescent;l also, tojprovide one or more burners'with'certain attachments where'-v by a strong draft is produced,and at the same time a steady light maintained. To such end I employ, in connection with the gas burner or burners, the attachments hereinafter described the annexed drawings,inf

and illustrated in which-A Figure l is a section taken ou a Vertical cen-.-

tral plane through a gas-burner provided with my improved attachments. 'Fig'. 2. is a like section of a modified form of construction. Fig. Sis a detail sectional view of a 'portion of Fig. 2 onafreduced scale. Fig.. 4= is a plan or top viewof the detlector G, shown inFig. 1. Fig. 5 is a section taken on a verticalplane through a multiple burner yprovided with attachmentsof a somewhat modified form, bt involving the same principles of construction as the attachments shown in Figs. l and 2. Fig. 6 is a top-or plan view of Fig. 5, and Fig.

i' is a plan 'view of the under side of the per.

forated jacket shown in said figure.

Referringby letter toFig.-1of the drawings, A iudicatesthe base or body of lthe burner,

which is adapted to be connected with van ordi-Q.

nary supply-pipe. Bindicates a perforated cup-shaped jacket, which is fitted upon the upper end of the body of the burner, connecf tion between the said two parts being prefer-v ably made by screwing the'burner-body into an internally screw-threaded sleeve, which is formed at the bottom of the jacket around an opening through which theburner-body passes.

. The globe or chimney()` rests upon a perforated rest or supporting-plate, D, which is provided B. REQUA, a oniat its rim with a iiange, E, and `with-a thumbscrew, F,'for the purpose of securing thechimney upon the plate. The plateisfsecured upon the perforated jacket, and is preferably formed 4in one piece with the deector G,.which`serves to direct the upwardly-induced currents of air around the tip and against the base of the frame 'from all. sides. 'lhe upper portion of this detlector is contracted Yand provided atits.

top with an opening,H,for thepassage of the flame. The burner-tip I extends within the said upper contracted portion of thedeiiector, and'has its body K, which is made somewhat longer thanusual, secured in the upper end of the body ot' the burner. lIt will be observed, however, that this body K, which is below the tip proper, practically constitutes a portion of the burner-body which extends within the perforated jacket.

When the burner and. its several auxiliaries are constructed and arranged as above-dcscribed, it will be seenthat by reason ofthe up.- ward draft through thechimney and of the draft through the passage between the tip and jacket, and thence pass upwardlyaround the tip tothe opening H in the top ofthe detlector.

The walls ofthe detlector will direct the air `against'the baseof theflame, and by reason of its upper contracted form induce a strong upward current, which will increase the ilame and intensify the heat. The upwardly-induced currents of air through thejacket and the passage through thedeiiector are indicated by arrows, an arrow being' also employed to indicate the upward current of air through the globe or chimney holder, which latter being perforated will admitair within thechimney, andalso allow the light to shine below the burner.

While in Fig. 2 the principles of construcltion are the same as in Fig. 1, the form of sme of the burner attachments is slightly different-as, for example, while in Fig. 1 the plate Iforming the chimney-support andthe deflector is concave-convex or bell-shaped, with its irregularly-shaped concavity ou the under side, in Fig. 2 the annular concavity ot' the chimneysupporting plate is onthe upper side and the deilector G made somewhat similar to an ordif IOC nary cone-deector. This deiiector unites with4 v `2c jacket and below the oritlce t the concaved or flaring chutney-,supporting l, plateat or about the line ofconnection between c provided at the top with a slot or opening,- H,

and the burner-tip is located withi-n, thede.

Hector, so that the walls ot' the latter will dellect the upwardly-induced currents of air against the baseot' the llame. ln lieu of elongatin-g -the body of the tip, as in Fig. 1,'it is made of ordinary size and the upper end of the burner-body extended up to a pointwhich is above the perforated portion ot the jacket'.

ln either case,fhowever,the result is the same,`

since in both instances the burner-tip, which is inclosed within a chamber formed by the pertoratedjacket and the superposed deflector, is located above the perforated walls ot' the at the top of, the deiiector.

In Fig.l 1,-L indicates an inverted basket or hollow frame ofplatinum,supported within the globe or chimney and over the burner-tip by means of rods -M, which are secured at their lower ends to a concavoconvex plate, N. This plate is held in place over the deiector G by vertical supports 0, connected with a collar, P,-

which is fitted around the upper contracted portion of said detlector. This plate N is providedwith a central aperture, Q, for the passage of the flame which issues trom the aperture in the top of the deflector G, and it serves as an upper auxiliary detlector for inducing and directing against the llame a current from the surrounding air within the chimney, as in- I ,dicated by the arrow q. The flame will heat the platinum basket or frame, which, upon becoming incandescent, will emit a brilliant light, and thus add greatly to the light from the flame. ,o l. t

In the construction shown in Fig. 2two pair of rods or supports, M, will be respectively located on opposite sides ot' the dellector. These rods will be connected above thel deflector ,by carbon wires or cross bars m, (shown in cross-section`,) thereby forming` the carbon frames L in planes parallel with the sidesot the flame. Y

Referring now to Figs. 5, 6, and 7, which illustrate a multiple burner, such as shown and describedv in Letters Patent granted to melon the 29th day of August, 1882, and therein eX- pressly stated as forming no part of said paten t', but reserved for a subsequent application,- A indicates the base or body of the gas-burner, which is provided witha single lower pipe, a, the latter being adapted iu any suitable way to connect with the supply-pipe, and being considered as a part of the burner-body. The burner-tips I are either formed with or secured to said burner base or body, and'each tip is surrounded by a dctlector, G, which is in the form of a truncated cone. The perforated plate D, for supporting the chimney C, is also adaptedto support a glass llame-protector, It, having a slot, r, parallel with the line ofP dellectors. The ilame-protector rests upon an annular seat, di, formed by a horizontal ilange of plate, D', while the chimney 7o C rests upon a lower annular lip, cl2, between an annular vertical portion, d3, of the plate and its marginal flange E. The plateD is perforated between the dellectors and the ameprotector It, and the vertical portion d3 of said 7 5 plate is also perforated,-as shown. The perforated jacket B rests upon and is supported by part tof the burner-body, and is Aconnected with plate D, so as to support both said plate and the d'ele'ctors. The platinum in this in- 8o stance is preferably made into the form of au oval-shaped plate,y L` concavert in cross-section and provided with perforations or slits. This strip has at its ends the supports M, which can `be fixed at their lower ends in any suitable 8 insulated blocks fitted in tubes or sockets secured to the end deilectors of the series. The upwardly-induced currents of air in the lastdescribed construction pass through the perforated jacket, and thence up and around the 9e tops to the llames,` the dellectors performing thc same service as that described ineonnection with the other figures.. Air will also enter the space between thcchininey and the flameprotector through the perforated portion d3 of Iplate D, while air will also pass up into the' space between the detlectors andthe liame-protectors through the perforations in the flange d of the said plate.

Having thus described my invention, what 1o I claim is 1. The combination, substantially as hereinbefore described, of the perforated cupshaped jacket B, the conical deliector G, secured over. the same, the perforated base-plate D,forming 1o 5 a chimney-rest, and a gas-burner the body of which projects into the chamberl formed by the jacket and thedelector and is provided with I a gas-burning tip terminating at a point beneath the top portion ofthe dellector, where-:11o by the intlowingeurrents of air are directed onto the base ot' the gas-llame on all sides beneath the top portion of the deliector, substan tially as described.

2. The combination, substantially as herein- I '15 before described, of the perforated cup-shaped jacket \B, the conical dellector secured over the same, the perforated base-plate forming a chimney-rest, a gas-burner the body of which project-s into the chamber formed by the jacket 12o and the defleetor,and is provided -with a gasv burning tip terminating beneath the top-portion of the deflector, and aplatinum' structure t 'supported above the dellector in the plane of the ilame issuing-through the slot therein, as set forth,

The combi-natiomwith one or moregas-1 burner tips incloscd by deilectors, ot' a perforated strip of platinum supported above the detlectors bymeans of intermediate connec- 13o tions, the body of said burner beingsurrounded by a perforated jacket which is litted to its body portion, whereby air entering the jacket will pass upwardly through the deilectors so 266,889' v Y a as to feed the flames and thereby develop-.'burner-tips being nclosed within the delectxof greater heat; for rendering lche platinum incandescent, substantially as described.

4. The combination, with .the body of a gasburner provided with one or more tips, of a. combined chimney-supporting plate and deljectors supported byaperforated jacket: which is ttcd to the burner-body and a platinum structure located above the deflectors, the

ors above the perforated jacket, substantially i.

as described. In testimony whereof I have hereunto set my hand in the presence of two subscribing,r witnesses. y
