HYDROCARVIBON-BURNER.

Application filed November 5, 1901.

To all whom it Imay concern.' l,

vBe it known that l, BURTON (l. HAMiL'roN, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented an improvement in lly lrocarbon-Burners, of which the following description, in connection with the accompanying drawings, is a specifica-tien, like letters on the drawings representing like parts.

This invention relates to hydro carbon burner apparatus for heating steani generators` or boilers, particularly such as are used in connection with automobiles.

ln an apparatus of this class it is desirable to have a inain burner to produce the principal heating eilect for raising and niaintaiin ing steain in the generator', and ordinarily the main supply pi )e or conduit for this niain burner is carried across or into the coinbustiou chamber immediately above the burner, in order that it may be heated by thc [laine lroin the burner and thereby serve as a vaporizer .to assist in vaporizing the hydro carbon iuei to insure complete vaporination thereol' before it reaches the burner. In starting the burner, however, to initially heat this vaporizer or seine portion o'l" the supply conduit for the main burner in order to obtain the requisite vapor, and to accomplish this niy invention comprehends an initial heating and lighting torch adapted when lighted to play upon the vapori'laer referred to and heat the saine to a degree suliicient to vaporize the contained hydro carbon. The main burner inay then. be turned on and the hydro carbon vapor issuing ti -erei'roni is lighted by the torch ilaine which furnished the heat for generating this vamp/pi i y invent-ion also comprehendsthe eniploynient of an automatic burner regulator res onsive to variations in steam. ressure wit iin the generator or boiler and W rich will vary the supply of vapor fuel to the main burner accor ing to the requirements of the boiler but without aiiecting the initial heattorch, which is independent of this regulator, .so that -when the main burner supply is Wholly cut oii for any purpose., the torch llainc may continue to fur nish such heatas may be necessary to maintain requisite pressure o i steam in the boiler ing and lighting it is necessary Specification o retters Patent.

and also to maintain the vaporizer heated.

and the ilaine in readiness for initially lightt'\being undesirable to permit the torch flame to play continuously upon the main burner vaporizer after said burner has been set in opera-tion, my invention corn rebends a movable torch, which, after initio. heating and lighting of the main burner, may be inoved or turned to one side vaway from the vaporizer to leave the latter free from the intense heat of the torch flame until such time as it is desirable again to bring it to bear upon said vaporizer, when said torchinay be moved back again into heating position.

The "foregoing with other features of my invention will be hereinafter more particularly described in connection with the accompanying drawings and the various features ol iny invention pointed out inthe claim at the end ol' this specilication.

ln the drawings, Figure 1 is a to or plan view, partial section, of a ortien o aburner appara-tus and boiler e uipped with devices made in accordance wit my invention su'icient to enable said invention to be understood; Fig. '.3 is a front, elevation artially'in section ol the apparatus shown in iig'. 1, certain parts heilig removed for ythe sake of clearness; Fig. 3, an enlarged sectional de'- tail, showing the torch illustrated in Figs. and 2., and, Fig. 4, a perspective detail showing the torch casing detached.

in the particular embodiment of my inillustration herein an shown in the drawings, A represents the inclosing wall of the combustion chamber of a typical seani motor vehicle,-.-such, for vinstance, as the well-known loconicbile of The bottoni of this combustion chamber is iornied by the burner, a, shown as provided Iwith 'a continuous top plate through whichrise the air tubes, a', surrounded by burner orifices, a2, through whichthe vapor fuel escapes from the chain` ber within said burner. The top of the combustion chamber referred to is shown in Fig. 2 as formed by the bottoni tube sheet of a tubular steam boiler or generator G of usual type. As herein shown, the combustion chamber, burner and boiler are of the general type and construction illustrated by S. Patent to Stanley and Stanley, dated Nov. 14th, 1899, lv 637,176, although my invention is not restricted to such apparatus to the exclusion of others.

Fuel vapor for the main burner is injected into the burner chamber referred to, through a mixing tube, l), entering through the side of said burner, the vapor injector nozzle being shown at c, and of such diameter relative to the diameter of said mixing tube as4 to cause a proper quantityv of air to be earried into said mixing tube' by and with the fuel jet entering thereat. The fuel for the jet device, c, is taken from a suitable receptacle not shown, land is conducted one or more times through the length of the boiler, as in a conduit, c', in well-knownmanner, and after entering said combustion chamber above the said burner, said pipe yor conduit,

u turned elbow, c,

' suitable joint packing, e2.

, leadlng c', is preferably given one or more turns, cv, or is otherwise suitably formed tov constitute a vaporizer, which connnunicates with the valve casting, c3. Communication between the interior of the valve casting, c", and the burner jet device, c, is controlled by a suitable valve, c". t

An automatic regulator, typified at D and connected with the boiler, so as to render it responsive to variations in pressure therein, is connected in suitable manner with a valve, shown in dotted lines at d, which controls the flow of fuel from the vaporizer, c2, to the valve, c", and its jet device, so that when the predetermined pressure has been obtained in said boiler, said regulator will reduce or cut off the fuel supply to the main burner, thereby to reduce the heating, effect until a reduced boiler 4pressure operates through said regulator to open said valve for an increased supply of fuel for further heat.

The valve casting, c", as here shown, is provided at one side with a downwardly to which is jointed, to swing about a vertical axis, the swinging elbow, el, the connection between the latter and said fixed elbow, e, being rotected by a rlPhe swinging elbow, c, carries a laterally extended tubular arm, e3, which, at its outer end, communicatcs with a suitably formed passage inthe torch barrel casting, e4, fitted witha valve, es, the handle of which depends in convenient position for operation. The torch barrel, c, is shown provided with a gooseneck,

from the said valve, e", and terminating at its end in an upturned tip, e7, rovided with a very fine aperture', e8, see 41ig. 3, directed towards the tubular neck, e, of said torch barrel. This neck, e", is shown smaller in diameter than the barrel proper, and preferably projects somewhat within said barrel, the latter containing preferably a foraminous screen, el.

Vapor from thel vaporizer, c2, entering the said casting, c, passes to the left therefrom and free from the control of the regulator valve, d, said vapor assing downwardly through the swinging e bow, e', and issuing from.. the orifice, e8, in a fine jet that is projected across the intervening air space 1nto and through the torch barrel, carrying with it a proper quantity of air, which may ignite so that the resultant flame will be projected upon the vaporizer, c`-, within the combustion chamber, A. The combustion chamber wall7 A, is shown as perforated at ax, to permit the entrance of the torch flame to play upon. the said vaporizer.

'lhe operation of my device is as follows:

Assuming the apparatus to be cold and the supply pipe or conduit, c, filled with liquid gasolene or other hydro carbon fuel, the operator first applies a lighted swab, o1", it may be, two or three lighted matches to the torch barrel casting and gooseneck, e", heating the same to a temperature sufficient to Vaporize the relatively small column of liquid fuel that is permitted to ass thereto. When heated to this extent..t e depending valve stem, e", is turned, vto'open the torch valve, thus admitting li uid 'fuel to the heated torch casting, by which it is"'immediately .Vaporized and projected by the pressure of the vaporizedfuel in a forcible jet from the orifice, e, into the barrel of the torch where it becomes thoroughly mixed with the air drawn in with it, and is lighted, it may be, by the same llame that was used to heat the torch casting, and burns beyond the foraminous screen, e, the force of the rejected column of vapor causing the flame o the combined mixture to play with intense heating effect upon the vaporizer, c2, of the main burner. When this vaporizer has been sufficiently heated to vaporize the containedhydrocarbon, the main burner valve, a4, vaporized fuel to passte the burner tip, c, from which it is projected as a forcible jet through the mixing tube, b, into the mixing chamber of the burner where it is mixed with the air drawn in with it and issues through the orifices, a2, j referred to. As this vapor issues from the burner it is immediately lgnited by the torchA flame, thus completing the operation of starting the main burner. l

As the main burner heats the boiler and its cohtained water, the liquid Vfuel passing therethrough in the ipe, c', is more or'less heated and vaporized efore reaching the vaporizer, c2, so that the effect vof the vaporizer is then as a superheater to raise the temperature of the vapor to a still higher degree, it being understood that the higher the temerature of the va or, the more intense will e the heat from t e resultant flame.

After the main burner has been started, thevaporiz'er, c2, will be heated thereby,\and it being no longer necessary to maintain vvthe torch flame playing upon such vaporizcr, the

is opened, to permit such seneca be in readiness again to light the main burner..

when the supply of fuel 1s admitted thereto alter having been temporarily cut od by the regulator, D, in the manner described. To

4facilitate the swinging of the torch into this abnormal position with its flame directed away from said vaporizer, the said torch may be provided with a suitable device, as the handle, E, Fig. 2, depending from the swinging elbow, e, which furnishes means by which the operator may readily and conveniently swing said torch into position to direct its flame in any desired direction.

l/Vhen the vehicle is stopped temporarily an hour or more, the torch flame alone projected into the combustion chamber is suliicient to maintain a working steam pressure for a considerable period ottime. For the best results at such times, the torch lame should not play upon theA vaporizer, for the flow of fuel therethrough would probably be insufficient to keep it from burning. When the vehicle is a ain needed for use, the heat of the contains water is sufficient to furnish va or for the main burner, and when admitte thereto, will be ignited by torch llame. ln the event, however', of the vehicle standing for such length of time as will permit the water within the boiler to cool to an extent that it will not vaporize' the fuel flowing downwardly through the pipe, c, therein, the torch -may in such event be swung into position to project its llame upon the vaporizer, c2, for a moment or two, whenthe main burner may be started as first described. 'lhe torch flame projecting from its barrel, e4, is alone sufficient to maintain said barrel and its adjacent fuel passage heated to a sufficient extent to vaporize its own fuel supplyk whether or not there be heat enough in the vaporizer, c2, to vaporize fuel flowing therethrough. To facilitate initial-heating of the torch by the swab ormatch flame and to shield such torch at such times from drafts of air, a suitable inclosing area is provided.

As here shown, there is applied to the combustion chamber wall, A, an outturned ringlike fiange, f, over which is fitted a cupshaped casing, f. The flanged ring, f, and cylindrical wall of the casing, f, are slotted horizontally, as shown in Fig. 4, to receive the swinging arm, e3,'o the torch, and also to receive the depending stem of the v alve, el". The casing, f', is retained in position upon the ring, f, frictionally, or otherwise if desired. At its outer closed end, the casing, j", is provided with a segmental o ening, f2, under the'cntrol of a rotatable dis r or valve, f3, Ahaving a handle, f, which when turned into position with its opening, f5, registering with the opening, vf2, of the casing, permits 4pending upon the conditionsof use.

of the introduction of the initial heating swab or matches. When the initial li hting has been eliected and the swab with rawn, the valve disk, f3,- is rotatedv to4 close the lopening, f, thereby protecting the torch 'itamrelgrom' action of air drafts. If desired, the opening, f2, may be left partially uncovered the adjustment of the disk valve deo gain access to the orifice, e8, of the torch, for cleaning, the casing, f', is withdrawn, permittin the torch to be swung completely aroun so as to face outward instead of t0- wards the burner, in which psition its several parts may be easily cleaned. y v

ln practice the swing arm, e3, is preferably filled with s elter or equivalent means for controlling t 9 flow of fuel therethrougha'nd to prevent fluctuations inthe torch flame.. T he perforated or foraminous screen, el, aids indissipating the fine column of fueland in 'mixing the same with the air, and also operates to prevent the flame lighting back to theorifice, es.
