OIL-BURNER.

SPECIFICATION forming' part of Letters Patent No. 428,096, dated May 20, 1890.

Application filed July 3l, 1889. Serial No. 319,242\ (No model.)

To all whom, it may concern: with an oil-tube 4, extending longitudinally Be it'known that I, MARTIN l-IATHAWAY, a under each of the burner-compartments 2, citizen of the United States, residing at Atand provided at one end with interior threads lanta, in the county of Fulton and State of 6, into which is inserted a threaded plug 7. 55 5 Georgia, have invented a new and useful Oil- Minute oil-openings 8 are formed throughout Burner, of which the following is a specithe length of the pipe or tube, and within the cation, area of the burners and said tube, is provided This invention has relation to oil-burners at its opposite ends with threads 9, in which' adapted for location in ordinary cooking is threaded a pipe-section 10,having an elbow 6o 1o stoves or ranges, or in the usual forms of heat- 11 at its outer end, which, by a second section ing stoves, the change necessary being sim- '12, is connected to a second elbow 13, having ply as to then umher of compartments, groupthe pipe 14, leading` to the oil-reservoir 15, in ing of the same, and othendetails not atfectthis instance consisting of a tank of the ordiing the spirit or principle of my invention'. nary construction, mounted upon a suitable 65 r 5 Among the objects in view are' to provide supportlG. If desired,and where convenient,

a burner of extremely simple construction the pipe-sectionl 14 may connect with any and at a reduced cost, which shall consist of suit-able natural oil-supplying system.` Above few parts and those readily manufactured theburner-pipe I arrange a sulliciently thick and assembled, and which may be lighted and layer of asbestus 17, and over the same a retic- 7o zo extinguished with facility and Without the ulated screen 18. By this it will be apparent disagreeable odor of the oil, and to provide an that oil passing through the pipes is fed into automatic governor for a proper supply of the burner-pipe and through the perforations the oil and so constructed as to automatically in the same up through the asbestus to the and entirely cut oil said supply when the Ypoint of ignition. Aburner thus constructed 75 2 5 flame of the burner is extinguished. is mounted in the grate-space of a stove, and Vvlith these general objects in View my inis preferably provided at its opposite end vention consists in certain features of conwith lugs 20, projecting upwardly from the struction and combination of parts hereinend walls. l after specified, and particularly pointed out 21 represents a cap having openings 22, cor- 8o 3o in the appended claims. responding'with the burner-openings 2 and.

Referring to the drawings, Figure 1 is a perterminating at each Side in lon gitudinally-arspective of a burner constructed in accordranged flanges inclined downwardly and conance with my invention, the same being nected at their centers bya transverse bar adapted for use in the grate of an ordinary 23 and end bars 24, the two latter having 85 3 5 cookingstove,.the lids of the burners being notches 25 at their middles for the reception removed. Fig. 2 is a central longitudinal secof the lugs extending from the burners, and tion of the burners; Fig. 3, a transverse verby which said cap is maintained in position tical section through one of the burners; Fig. thereupon. Independent covers 26 Vare pro- 4, a detail in verticalsection of the oil-supply vided for each of the burners and remain 9o 4o pipe, the section being taken at that part upon'the same, except when the burners are thereof wherein is located the automatic oilin actual use, thus excluding the smell of oil, supply governor and automatic cut-off. and when the burners are lighted serving to In practicing my invention I prefer to cast extinguish the flame by cutting olf the airall of the parts of iron, and the same consupply.

45 sists, essentially, of a burner-section 1, in this The pipe that connects the two elbow-sec# instance comprising two burners or comparttions is divided into upper and lower sections ments 2, divided transversely to form the 27, the upper section terminating at its lower same by means of a partition 3, which is pro end in a conical valve-seat 2S, and the two secvided with an intermediate air-opening 33, tions being connected bya cylindrical valveroo 5o extending throughout the length of the parchamber 29, the internal bore of which is tit-ion. The bottom of the burner is provided greater than that of the pipes they connect.

30 represents a valve, the upper end of which is cone-shaped, as at 31, and designed to lit the seat in the lower' end of the upper' end ofthe pipe-section. The valve is preferably made of cork or other light material, and the size of the saine is such, when considered with the length and diameter of the valve-chamber, as to leave an annular recess oroil-passage around the valve. An ordinary eut-oft 32 is provided in the oil-pipe near the supply and is used for entirely cutting oft the supply of oil ordinarily; but it by inadvertenee the operator should fail to operate the cntolf aft-er the extinguishment of the flame, the unburnt oil within the burner-tube would back up and form a backward pressure against the bottom of the valve and force the same to its seat, thus preventing a feeding' ot' oil to the burner and automatically cutting oft the supply. The valve also operates as aregulator or governor for the oil while being consumed, in that should the oil pass too freely to the burner the valve operates, as before described, to more orless decrease the flow; and, on the otherhand, if the consumption is greater than the supply the valve is maintained below its conical seat and its opposite end upon the upper end of the lower pipe-section, which is provided with a series of perforations 33, through which the oil passes to the burnerpipe.

rlhe slanting sides or flanges of the cap form a space between the cap and the edges of the burner-compartment anda draft of air is induced to join the flame at the point of ignition, thereby increasing the intensity of the fiame.

Having described my invention, what I claim is- 1. An oil-burner consisting of a casing plovided with a series of open-top oilburning compartments or chambers having a common supply-tube extending across the bottom of the same, and provided with openings for the supplyot oil to the compartments, removable lids for each of the compartments, anda cap mounted over the compartments and spaced from the sides of the same forming air-passages, and having openings in itsl top corresponding to the burner-compartments, substantially as speeiiied.

2. An oil-bnrnerconsisting of a casingprovided with a series of partitions integral therewith and dividing the casing into a series of burner-compartments, each partition being provided with a transverse air-passage communicating with the atmosphere at each side of the compartments, substantially as specified.

3. The combination,with the burner-casing consisting of side and end walls and a transverse intermediate partition dividing the casing into two compartments, of an open cap provided with end bars adapted to rest upon the end walls of the casing, and with an intermediate transverse bar adapted to rest upon the partition, opposite side fianges connecting the bars depending below the same and supported above and away from the side walls of the easin g to form air-spaces, substantially as specilied.

el. In means for supplying oil to hydrocarbon-burners, the combination, with the supply-pipe consisting of upper and lower sec tions, the lower end of the upper section being provided with an internal conical valveseat, and the upper end of the lower section being reduced, perforated, and terminating in a plain seat, of the intermediate cylindrical valve-chamber connecting the adjacent ends of the sections, and a buoyant valve located therein, thelower end of which is plain and adapted to rest upon the plain seat of the lower section and the upper end conical and adapted to operate in the conical seat of the upper section, substantially as specified.

In testimony that I claim the foregoing as Ymy own I have hereto atixed my signature in presence of two witnesses.

MARTIN IIATI'IAIVAY.
