This invention relates to certain new and useful improvements 'in 'hydo-carbon burners adapted to burn in stoves,.furnaces, etc., the coarser grades'of crude oil,-and is an improvement on the invention for which I made application for Letters-Patent on the 7thv day of November,

' A a 'tubular air.y intake member,

reference The presentl invention consists incertain novel features of construction and arrange-d ou t in case, w

ractice since the filing of the above ich will be readily understoodby to the description of the drawings and to' the appended claims.

One ofthe objects of my invention is to avoid the use of a solid metal spreader or baille plate-and he reason for this is that such a bailie plate always gbecomes covered with soot which by its presence tends to poor combustion and eventually to more or less imperfect action in the operative process of producing gas from oil. Because of the peuliar construction. of' my device' with an additional air supply introduced through a strong A' draft is created which 'impinges against Aspreader is the `upward flow of the mixture' extcrior thereto,` whereupon the flame is spread in an almost horizontal plane as by a baille plate, yet entirely without the use of one. {In this manner the impedance 'of the gas, against such plate is' entirely avoided and the creation of -soot thereby,`

suchI as occurs in the use of Vthe usual entirely obviated.

'Another objectof my invention is the. provision of-a vaporizin plate so located and positioned that it wi l vact in the man-A ner of aclosed retort, although it is really not one, for itis not in any manner fasten- Yed Ato the base plate but simplylrests lightly thereon, and is in nov way resistant to the of theI gases action of explosive i 'forces should Athey become improperly ignited. a A further object V f my invention is to' provide a hydro-carbon vburner `which produ'ces aggas similar to producer gas, that is to say, a gas mixed with an insuilicient 4amount of air to produce combustion whatever may be the adjustment of the burner, the `mixture as it ascends, reaches av 1923, Serial-No..

To the free end 14 of the lever is pivotally secured a bell crank lever15 Whose other end 16 descends towards the bottom of the stove 17 where it'is pivotally secured tothe stem 18` of a valve in thel coupling 19, the purpose of which is to thev suppl-y the small tank 22 to the burnerwhen the steam pressure becomes excessive.'

The supply pipe 21 at a point a little nearer the tank is provided with a second coupling 23 having a valve seat therein. he stern 24 thereof is mediately attached to a balance rod 25 having a weighted ball 26 hanging from one end and a can 27 from the other end into which opens the free end of an overflow supply pipe 28, (see Fig. 2). It will be noticed that when the weight of the oil from the overflow supply pipe into the the valve is oil from the closed, shutting offthe flow of burner is eX- tank 22, and the flame. of the tinguished.

The small supply tank 22 is provided on its under surface with an ordinary globe cut off valve 30 by means of which its supply to the furnace may bevcut oil", and upon its upper surface is rovided with a supply pipe 31 and an over ow pipe 32. The large supply tank 33 is provided with a supply pipe 34,from which the oil'is delivered into the cellar from the outside, and an overow pipe 35 through which the oil exists on the outside of the house. should the tank become oversupplied, and to this pipe 35 is also` connected the oversupply pipey 32 from the sma. tank. Upon the top of the larger 'tank is secured any suitable pump mechanism 36 for pumping the oil into the supply pipe 31 of t e smaller tank-22, but as these part of my invention, they will not be further described.

Centrally located upon the 'gratebars 40 of rthe furnace by means of headed bolts 41v and nuts 42, is my improved burner, the same consisting of a base plate having cast integrally therewith on its exterior edge,l an "upper cylindrical wall 43 having at equidistant intervals several supporting bars 44. Each of the supporting bars is cut away onv its upper exterior-wall, as at 45, and at the base of suchl supporting bars the metal flares outwardly into the flanged plates 46 which are perforated for the reception ofthe binding posts 47 which hold together the body of my structure and the right angled annular flange 48 which isprovided with apertures 49 for the reception of said posts. Said flange on its interior is provided with a shoulder'l upon which latter the cone 52" is adapted to seat itself, al support from the rtop b of the supporting ars receiving addition;

-. arise. The upper side o Cast integrally with the base vplate is a tubular member 53 which extends up through thev center of. the cone to a. point somewhat beyond said cone' and other portions of the detachable cap 54 which more fully described. f

The floor of the base plate 55, as more clearly seen in Fig. 4, is provided with an inner annulaigroove 56, an outer annular groove 56', an annular ridge 57, and ata point 57 meansof which .56 may enter into the interior groove/56. As oil, like any other liquid, seeks its own level, the arrangement of the grooves enables myimproved burner levelled and positioned in the furnace, and

device and is provided with a,

will be hereinafterl to be properly v with a depressed oil passage 58 by 1 the oil in the exterior groove gives also an even d stributlon of'oil inthe tion with my vaporizing plate or retort 60, f

which consists of an annular vided with apcentral opening 63 which enables it to be fitted over the tubular air inlet member 53.- It'is further provided on its lower peripheral edge with a downwardly extending ridge64. It ito be noted that the outerase, or that part between groove 56 of' the plate 62 prothe lower portion of the cylindrical wall and the ridge 57 -in the base is to be filled with cement and the vaporizing plate positioned in placeand pressed down upon the ridge so that its downward ridge may become indented in the cementvwhile wet, whereupon the vaporizing plate is 4removed and the cement allowed to dry out and harden in place with said indent therein, after which the vaporzing plate is vagain placed in posi'- tion. This cement plug or block at the far end prevents the gas from escaping at that point and directs the hot p oint Vtothe base of the`tubular member, thereby greatly aug-A menting its draft.

In the arrangement mentioned lies a very important feature of my invention for by this'construction we have oil in the groove 56 between the tubular air inlet member and the ridge 57 in the base, and the base is thus practically a retort. Onl the other hand, the vaporizing. plate and base do not consti tute a retort because said vaporizing -plate is loosely mounted and unattached at any point to the base, and is thus `non-resistant 'tbany Vexplosive force of ases which may the vaporizing lao with` a holding lug 61, by means of which the plate may be ing .per up turned orI lifted. l Reference is now made to Figure 5, show-- the cone detached, and to Figure 3, showing the cone resting in its proper position upon the interiorlyextending flange or seat51 and the upper ends of thesupporting bars 44.-

The body of the cone is indicatedV by the numeral 6 5. It i's of circular formation, gradually flaring as it ascends, and decreasing as it descends until its loweredge is within the upper cylindrical wall 4:3, while its flaring upper edge is of a size to it loosely within the interior periphery of the circular right angled flange 48. The upsurface of the cone is provided on its per edge with a turning lug 67 by lmeans of which the same may be turned or lifted. The under surfacerof the cone 65 is providedwith a series of three inclined edges 67', the lower edge of each of which is formed into a double cam, the first' of which ends in an abrupt notch 71 and the latter of which similarly terminates in another abru t notch 72. Each of the three cams is of l' e construction and size, and by means of the turning flange 67, the cone can be turned in a gradually ascendingv or descending circlefrom'the point 73't0 7 4 and again from point 74 to the still higher point 7 2, enabling the operator tof'gradually vary the slze of the opening between thev vaporizing plate and the lower,y edge of the cone, thus lessenor increasing the" draft. From the above it will be -se'en that-the regulation of 'the cone isj'suchas to permit of a wide en` trance for the air between these' points, -m which event the clearancebeing much, the draftgwill be small. On' the 'other hand, if

- the regulation is such as to bring about a .stack-draft in the chimney,

v special rather small clearance, then the draft is strong, and through the concentration of the effect of a the use of 4any mechanism for that purpose..

. My devicehas no baille plate, but upon the top of the .tubular member, I place -a cap 54, the 'same consisting of a'small solid y its upper side a Oldlng 01' lifting plug 76, and the lower blower is achieved without part of the plate 'graduallydescending into a point 77. Depending from` its lower periphery are three legs, as indicatedat 78. The lower inner edge of the legs are somewhat attentuated, asa-t 79, sd as to fit within the interior of'the tubular member, perl mitting the notched edges 8.0.. to sit squarely upon the. top of the'member, thusleaving a circular air space of less than one-half inch" in heighttubular'member-except,` where the legs rest on thetop of said member.

In Figure'l the burner vis shown' mounted and the remaining area of pressed channel 58 goes immediately shcc'eeded by perfect comb and volatilizlng heated and mixed withthe gas and the effect through all around the top ofthe upon the grate bars of afurnace.- The-j burner `is set in the centerof the grate bars such` bars is-covf metal 82, and the burner ered with a sheet is also surrounded by a vertical sheet metal wall 83, as seen in `Figuref. A mixture of concrete 84' is then poured over the sheet metal until itis covered up to the point 85, and the same is allowed to dry. The object of this. is to prevent the entrance of .any air above the grate bars save that which comes up through and around the burner, as i-nd1- cated by the arrows in Fig. 2, and in this way a strong draft is secured through the tubular'air member in the center of the base and also around the exterior and interior sides of the cone and -up through the cone to the top of the burner;

The operation of my device isas follows: The oil being turned on, enters through the fuel supply pipe 21 upon the base of the burner, the groove 56',

inner groove 56 and' through opening through and through the dedirectly into the the 'circular which the tubular member rises, and to the upper surface thereof of the vaporizing plate.` A lighted rag covered with oil is then thrown upon the plate and for the space of a minute there is considerable smoke arising from; the imperfect combustion dueto thev cold conditionl of the furnace. This, however,l is

tion'and the entire absence of smoke, the vaporizing plate rapidly becoming heated the oil into'` gas. .The amount of oxygen pplied to the gas ariss not, however, s uiing isv to make a mixture somewhat similar to producer gasin burn, since the quantity of air supplied 1s insuiiicient to produce ,complete com usti This is the case either when the cone is .adjusted toits highest or'lowest level and notwithstanding the mixture-may. have ascended within the cone up jacent to the outlet of the tubularl cone'. At this point, however, the tubular with, and by means of the cap 54, the draft coming up member 1s ydiverted practically in a' lon 1- tudinal plane into .the 'mixture without. t e

tubular member. already referred to'and the Y' needed to pro-- additional amount of oxygen duce perfect combustion is afforded and takes place. A

In this connection it may be stated that the ordinary baille plate or metal spreader heretoforeused has been found undesirable and has always interfered with thepe'rfec't 1t Wi/11.116013# working of'an oil burner.

the air coming up' member unites there' through the center of the tubular that said mixture will not T served, however, that' I have no baille plate,

,injected into said the current of air rising through the tubular 'member and spreading outby reason 'of-the cap so as`to unite with the exterior mixture forms its own baflie'. plate as it is mixture and produces combustion without any impedance of gas by such a plate.- instant case, the air goes up in a vertical plane through Vther tubularmember and passes out therefrom in a practically -lon- 'gitudinal plane without any impedance ot' a plate, such as a ballleplate, simply by the force of the air rushing through the tubular `member .at 'which moment perfect combustion takes place without the use ofa plate.
