.To all whom, it may con/cem:

Be it known that I, EDWIN G. MUMMERY, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Hydrocarbon-Burners; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apart of this specification.

My invention is designed to provide animproved hydrocarbon-burner of superior eiliciency and utility; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in Which- Figure 1 is a vertical section on the line 1 l, Fig. 2. Fig. 2 is a plan view of the vapor izer-holder withl the vaporizer in place. Fig. 3 is a separate plan view of the vaporizer. Fig. 4 is a vertical section on the line 4 4, Fig. 2. Fig. 5 is a horizontal section on the line 5 5, Fig. l. Fig. 6 is a side elevation of the burner complete. Fig. 7 is a separate plan view of the vaporizer-holder. Fig. 8 is aseotional View on the line 8 8, Fig. 2., l

The aim of my invention is to provide a hy'- drocarbon-burner whereby the hydrocarbon may be more quickly and more satisfactorily vaporized and complete combustion secured, without a wick and without folensive odors, in a very simple and economical manner, the burner being easily operated'. l

I carry out myinvention as follows:

A. represents a vaporizer-holde'r, which is preferably made ofcast metal of suitable heft to form a firm and suitable support for the burner as a Whole. This holder is constructed with an interior orifice, vas at A,surrounded by a channel A2, the holder being provided with upwardly-extended flanges a. and a to form the channel A2. The holder is also constructed with an exterior channel A3, said channel being formed by upwardly-extended flanges a2 and a3. The channel A3 is preferably constructed with a series of elongated slots a4., through which air may freely circulate. rlhe holder is also provided with openings A", throughwhich the air may freely pass upward. The channels A2 and A3 communicate one with another through a connecting-channel A5, constructed with upwardlyextended flanges a5 and o5, a brace A6 preferably connecting the channels A2 A5 on the side of the holder opposite the channel A5. The various flanges of the vaporizer-holder are provided with vertically'extended ribs,

(indicated at al.) These ribs on the anges a2 a3 are preferably formed with shoulders or steps, as at a, toward their lower ends.

` B denotes a vaporizer made of suitable sheet metal, as of copper, the sheet metal being comparati vely thin in order that it may be the more quickly heated. This vaporizer B is formed with an interior orifice (indicated at B', Fig. 3) corresponding to the orifice A of the vaporizer-holder, with an interior channel B2, corresponding to the channel A2 of the holder, with an outer channel B5, corresponding to the channel A8 of the holder, with an air-space B, corresponding to the air-spacesA* of the holder, and with a connecting-channel B5, corresponding to the channel A5 of the holder. These channels are formed with lateral flanges b b' about the inner channel B2, and

With'lateral flanges b2 b3 about the channel B3. The channel B5 is formed with lateral flanges b"v b5. The vaporizer B is located within'the channels A2 and AS ofthe holder, the connecting-channel B5 being 'located in the channel A5 of the holder.

The vaporizer Bris supported, preferably,

a little above the base of the holder, as upon the shoulder or step as of the ribs of the flanges a2 a3 of the holder. The outer flange b3 of the channelB3 is preferably extended above the upper edge of the inner flange b2 of the chan- .nel B3, and is provided with a series of per- ICO admitted into. a channel, asIAS, in the holder having a closed base some difficulty has been experienced in lightingthe fuel and securing proper vaporization thereof at the outset, owing to the length of time necessarily required to properly heat a cast-metal vaporizer, embod yin g, as such a structure necessarily does, a yconsiderablel amount of metal comparatively, in consequence of which imperfect vaporization is at' the outset secured, and the hydrocarbon fuel, as gasolene, is liable toaccumulate in such a vaporizer because it is not readily vaporized and consumed, while such a'vaporizer is becoming sufficiently heated. The result is that where the valve in 'the feed pipe C isopened, as required in the subsequent operation of the burner, the fuel accumulates to someextent, as above observed, in the outer channel ofthe vaporizer, and when the castmetal vaporizer, as heretofore constructed, has become properly heated, so as to consume the fuel, the fuel blazes up in an undesirable and unsatisfactory manner until the extra supply of fuel has been exhausted, on account ofA which the odors of imperfect combustion escape into the room. f y

My pesant invention is particularly adaptf ed and designed to overcome effectually any such liability andobjection to burners heretofore used, and therefore in carrying out my invention I employ as a vaporizer a vaporizer formed of comparatively thin sheet metal, copper being preferred, as heretofore ob served, the vaporizer of thin -metal beingr formed with the channels, as heretofore described, this vaporizer being supported upon the cast-metal holder above set forth, the outer flange of the outer channel of the vaporizer B being perforated; toward its upper edge, Vas specified, to admit adesired amount of air into the outer channel ofthe vaporizer to mingle with the hydrocarbon fuel to provide for perfect combustion.

It will be readilyseen and understood that a vaporizer made of'comparatively thin sheet metal will be very quickly heated when the fuel is lighted, on account of which' the burner will quickly produce a proper vaporization of the fuel at the very outset, which vaporization will of course be continuously kept up while the burner is in use. In this way all liability of an undue accumulation of the fuel within the sheet-met-al vaporizer in starting the burner into operation is effectually prevented and the flaming up of the burner, heretofore mentioned, is also prevented, together with the escape of any odors, as imperfect combustion is overcome and perfeet combustion secured almost instantly when the burner is lighted. This permits the valve to be opened inthe supply-pipe to the full extent desired in the operation of the burner at the very first, as is desirable in order to insure simplicity andg satisfaction in y vaporizer.

' About the outer and inner periphery of the channel B3 of the vaporizer I locate foraminous walls D D. About the outer and inner peripheries of the channel B2 of the vaporizer I locate corresponding foraminous Walls D2 D3. These walls may be supported upon the vertical ribs al of the inner and outer flanges of the channels A2 and A3 of the holder. The vaporizeralso may be riveted, if desired,l to the ribs el. The walls D D DZ'DS, I prefer to make of wrought or sheet metal suitably perforated to make them foraminous. It is evident that these walls become very much heated in the operation of the burner, and where formed of cast metal made foramnous the accidental spilling of water thereupon may cause the cast-metal walls to break. With the walls made as above set forth this liability is obviously entirely overcome. l therefore design to use wrought or sheet metal in their construction.

E denotes a cap covering the interior chainber forined by the wall D3. e EAis a cap covering2 the chamber formed between' the walls D' D .E3 is a cap projecting downward from the top of the wall D thereabout. Thesel caps may be engaged in position in any suitable manner.

It will be obvious that the forami'nous wall D3 forms an interior air-chamber F, into which the air may freely pass through the openings A' B in the holder A' and vaporizer B. The walls D' D2 form an intermediate airchamber F', into which air may freely pass through "the openings A4 B4 in the holder and An additional air-chamber F2 is formed between the outer cap E and the foraminous wall D, which chalnberis open to the atmosphere at the base of the cap E2. Above the vaporizing-channels B2 BP of' the vaporizer are thus formed combustion-chambers G and G', open at the top, as shown. These caps E E E2 may be made of cast metal constructed to engage the upper ends of the corresponding foraminous walls; Intermediate the upper and lower edges of the foraininous wall D3, I locate a horizontal partition H. Between the upper and lower `edges of the wallsD D, I locatea similarvhorzontal partition H', while between the foram` inous wall D and the capilla, I- locate a similar horizontal partition l-I2. These partitions 1I IfI H2, as indicated more especially in Fig. 5, are constructed with orifices h, lpreferably elongated, through Which the 'air may freely pass into the regions of the chambers thereabovc. The caps E E are also provided with suitable perforations or orifices, as at e,- preferably elongated. 'lhe partitions III-I' ll2-are employed for the purpose of holding the rcspcc# tive parts adjacent thereto in place.

It will beunderstood that when the burner is iny use the foraminous walls. on the innerf and outer peripheries of the respective com.-

-bustion-chalnbcrs become very highly heated,

the surrounding foraminous Walls on both the inner and the outer peripheries of each chamber, the bulk of air being admitted into the combustion-chambers through the lower perforations of the walls.

Attention is particularly called to the fact that the lower edge of the foraminous wall D is spaced from the upper edge of the outer flange a3 'of the holder, as more clearly shown j of the flanges c5 da.

in Fig. G, in order to permit air to circulate freely through the perforations in the outer fla-nge b3 of the vaporizer B into the adjacent vaporizing-channel.

Over the channel B5, I locate a removable cap J, which may be bolted upon the flanges By making this cap removable, access can readily be had into the channel B5 in case of anyobstruction or obstacle getting located therein, whereas if said cap were not removable it would be diiicult tok get access to said channel. The upper orifices c in thel caps E E are preferably elongated, as before stated, so as to let the air that may accumulate in theupper portions of the corresponding chambers F F' more freely escape. These caps E E' E2 are employed chiefly to defiect or hold down the air to cause its passage more eiiiciently through the foraminous walls of th e combustionchambers. At the same time,in order to prevent an accumulation of dead air 'in the top of the ai r-chambers and to prevent an undue deflection of the heat downward thereby, it is desirable to provide the slots therein, as above described, so that there may be a desired circulation of air therethrough to prevent the accumulation of dead air and to allow the heat to escape upward. The partitions may be secured to the adjacent parts in any desired manner, as by forming them with ears and riveting them to said parts.

I prefer to extend the outer flange b3 of the vaporizcr upward above the upper edge of the flange a3 of the holder and perfor-ate it, rather than to extend the foraminous wall D downward to the said edge of the flange a3, in order that the vaporizer may become more quickly heated, as by this construction the initial heat, when the burner is lighted, is more confined to thevaporizer itself. The air coming in through. the perforations in the flange b3, and over the edge of the adjacent flange b2, supports the initial combustion within the channel B3, and as the flame will cling to the solid parts of perforated flange b3 between the orifices the vaporizer will be much more quickly heated than if the heat were in some measure transmitted to an independent wall above the channel B3.

The outer wall D is disconnected from the holder, it will be seen, exceptwhere it rests upon the ribs a7. This construction limits materially the transmission of heat to the holder, confining it more eifectually to the. upper parts of the vaporizer, on account of which vaporizationis more quickly and more e-Eectually obtained.

The vaporizer Bis preferably riveted or otherwise rmly secured to the holder, asindicated at O, to'hold the parts together and` prevent warping. The foraminous walls and the caps E E are preferably removable.

What I claim as my invention is l. In a hydrocarbon-burner, the combination of a cast-metal holder provided with annular communicating channels A2, A8, a thin sheet-metal vaporizer formed with similar communicating channels located within the corresponding channels of the holder and sup ported thereby, and a feed-pipe leading into the channels of the vaporizer, for the purpose set forth.
