T aZZ whom it may concern: trough. The oil to be burned is supplied to Be it known that I, LOUIS GODDU, of Winthe shallow trough through a pipe communichester, county of Middlesex, State of Massa-- eating with the outlet-port of a valve-casing chusetts, have invented an Improvement in containing, preferably, two independent Petroleum-Burners, of which the following valves, one of which is controlled by the 5 5 description, in connection with the accompapressure in the boiler to cutoff the supply of n ying drawings, is a specification, like letters oil to the burner, the other of which is oper on the drawings representing like parts. atively connected, as will bedescribed, to a This invention relates to apparatus for regulator, which may be a float located in a T0 burning oils, especially unrefined oils, such chamber or vessel communicating with the 60 as crude petroleum, and is an improvement interior of the deflector referred to, so that upon the apparatus shown and described in excess of oil in the deflector may flow into another application, Serial No. 250,705, filed the chamber or vessel, and, by raising the by me September 26, 1887. float automatically, cut off the supply to the Prior to my invention I am aware that atburner, or the said regulator may be a cup 65 tempts have been made to employ crude peor receptacle connected to the valve and troleum as a fuel for heating purposes; but adapted to receive oil from a pipe connected prior to my invention this has not been sucto the deflector.

The burner is herein shown as composed of an annular shallow trough at, having secured to or forming part of it an upwardly and preferably outwardly expanded or extended side i wall a. The side wall ct is provided on its outer side, as shown in Figs. 1, S, and 9,with legs or studs a which project down at intervals, so as to leave an opening a between every two adjacentlegs for the passage of air. Each depending leg a as herein shown, is provided with a slot, into which is fitted the upper end of a concaved plate or wall a", constituting adeflector, the said legs being secured to the said plate or wall in any desired or suitable manner.

Thedeflecting-wall a is shown in Fig. 1 as circular in form to conform to the shape of the shallow trough, and the said deflectingwallforms with the outer upturned side of the said trough a passage a through which the flame from the burning oil is directed down under and in contact with the bottom of the shallow trough.

The deflecting-wall a in the present instance is cored annularly near its upper end above the shallow trough to form a circumferential passage a, having its inlet separated from its outlet by a suitable partition or wall indicated by dotted lines a Fig. 6, the passage a", having its inlet mouth or port connected to a steam-inlet pipe a, provided with a cock or valve a the outlet end or mouth of the passage a communicating with the radial passage a formed in the deflecting-wall. The passage to extends down to thebottom of the deflecting-wall a and communicates with the interior of the burner through a port, which is controlled, as herein shown, by a plug-valve a The steam-inlet pipe (1. in practice is connected to the steamdome-of the boiler.

The passage cflat its upper end, preferably at the junction of the said passage with the circumferential passage 0., may be provided with an outlet-port a located above the shallow trough a and adapted to admit steam into the space between the side walla and deflectingwall a, above the said trough, the said outletport being controlled, as herein shown, by a plug-valve 17, extended through a hollow arm b of the deflecting-wall a, the said arm bei ing extended through the side of the boiler,

as herein shown, and provided with a suitable stuffing-box b of any usual construction.

The oil to be burned, which in practice is preferably crude petroleum-oil, is supplied to with a suitable valve or cock I). The threaded nipple b is preferably connected by a glass or other transparent tube or pipe 19 to another nipple 19 which communicates with the outlet-passage I) (see Fig. 11 and dotted lines,

Fig. 3) of a valve-casing 0, herein shown as a tube secured to or forming part of the shell b, it. being shown as secured to the top thereof.

The valve -casing contains, as herein shown, two independent valves 0 c preferably made as hollow tubes and provided with valve-stems c 0 extended through stuffingboxes 0 c, secured to the opposite ends of the valve-casing c. The hollow valve 0 is provided, preferably, with a longitudinal slot 0 constituting a port, which registers with the port 0 in the shell or case b, the port 0 constituting the inlet-port of the valve. The'hollow valve 0 is provided with a preferably transverse or radial slot 0 to register with the passage 11 the said slot constituting the outletport for the valve. The valve is preferably made in two independent sections 0 0 so that they may be rotated independently of each other, for a purpose as will be described. The valve-stem c has its endpreferably made square, or of other than round shape, to be engaged by a lever d, to which is connected one end of a link at, having its other end connected to a weighted lever (P, which is raised and lowered by the steam-pressure within the steam-dome of the boiler acting on a diaphragm d of a regulator of any usual constructiomand such as known in the market as the Clark regulator.

It will be seen that the supply of oil from the case or shell Z) passes through the ports c 0' into the valve 0', and from thence into the valve 0 and the said supply will be automatically cut off by rotating the valve 0 from the position shown in Fig. 2 to that shown in Fig. 11, so as to bring the port 0 out of line with the port 0 which rotation is effectedby the raising of the lever 61 by the steam-pressure in the boiler.

The valve-stem c of the valve 0 has its end preferably made square, or of other than rounded shape, to be engaged, as herein shown, bya lever d provided with asegment of a gear c with which co-operates a segment of'a gear d on a lever 61 which may be connected by a'link d to a float al located in a vessel or receptacle (1 the latter having its bottom connected by pipe (Z to the lower end of the deflecting wall a near the bottom thereof, the lower end of the said deflectingwall being upturned to form a shallow basin to receive any excess or surplus oil whichmay overflow from the shallow trough a, the said excess flowing off through the pipe (Z into the vessel d, in which it accumulates and raises the float, and through the levers d (l rotates the valve 0 from the position shown in Figs. 2 and 11 to one substantiallyat right angles thereto, so as to bring the port 0 out of line with the passage I), and thus close the outlet-port of the valve 0 and out oh": the supply of oil to the burner. It will thus be seen that the supply of oil to the burner is antomatically regulated, not only by the steampressure which operates the inlet-valve, but also by the excess of oil which operates the outlet-valve.

The plug-valve a, controlling the admission of steam into the center of the burner, is connected to one end of a lever 6, extended beyond or outside of the boiler, which may be operated by the foot or otherwise.

The boiler will be provided with usual dampers, (not shown,) by which air may be admitted to the fire-box A In the operation of my improved burner the oil admitted to the shallowtrough a is ignited, and the air in the fire-box A passes through the spaces a and down through the passage a carrying with it the flame arising from the burning oil, the said flame being thus brought beneath and in contact with the bottom of the shallow trough CL, thereby intensely heating the same and enabling the crudest petroleum to be burned without deposition of residue, the said flame passing up into the fire-box, as indicated by arrows.

I have herein shown in Fig. 1 the shallow trough a and its sidewall a as circular in form, as is also the deflecting-wall a; but I do not desire to limit my invention to this particular shape of apparatus or burner, as it is evident that the same may be changed, according to the kind and shape of boiler with which it is to be usedas, for instance, when employed in connection with the locomotiveboiler the said shallow trough may be made substantially straight and of considerable length, and the deflecting-wall a in this instance may be made of considerable length to co-operate with the said burner, substantially as shown in Figs. 4 and 5, wherein a burner comprising a shallow trough, its side wall, and the deflecting-wall co-operating therewith are shown.

I have thus far described my improved burner as employed with boilers in which a substantially high steam-pressure is attained; but I do not desire to limit my invention to the use of my improved burner with boilers as described, as it may be used in furnaces and like apparatus, and especially to heat boilers carrying only a low steam-pressuresuch, for instance, as used in apartment hotels for heating purposes.

When used with furnaces, the burner will preferably be made substantially as shown in Figs. 8 and 9, the deflecting-wall a at the center being recessed or made cup-shaped, as at 25, to receive a small quantity of water, which may be supplied either by a pipe or nozzle 26, extended up through the bottom of the deflecting wall, as shown in Fig. 9, the said pipe or nozzle being connected to a supply-pipe 27, provided with a cook or valve 28, or the said water may be supplied by a pipe 30, extended through the side of the deflecting-wall and connected to the supply-pipe 27, as shown in- Fig. 8. The supply-pipe 27 may and prefer ably will be connected to a supply-tank (not shown) located at a sufficient height-as, for instance, at the top of the building-and the supply of water may be regulated to a nicety by the cook or valve 28, so that but a single drop of water at a time maybe brought in contact with the bottom of the deflecting-wall, which bottom being intensely heated immediately converts the water into steam, and thus assists and renders perfect the combustion.

I have herein shown the side wall a as an integral part of the shallow trough; but it is evident that the said wall may be an independent part fastened in any suitable manner to the shallow trough.

The parts of the burner will preferably be made of iron; but instead thereof they may be made of fire-clay or other refractory material.

I have herein shown the side wall a provided with lugs which rest upon the deflecting-wall and leave air-spaces; but I do not desire to limit myself to this specific manner of supporting the trough and its attached side wall, as the said parts may be supported by bars 33, secured to the trough and to the deflecting-wall, as shown in Fig. 10, or in any other convenient manner.

Referring to Fig. 7, the overflow-pipe d discharges into a cup or Vessel (Z connected to the valve-stem to close the inlet-valve.

I claim 1. The combination, with a firebox, of a shallow trough suspended therein to receive and hold the oil to be consumed and a deflector located outside of and extended below and underneath the shallow trough to form a passage for the products of combustion contiguous to the shallow trough, the air admitted into the fire-box drawing the flame from the surface of the oil in the trough down under and in contact with the bottom of the trough, whereby the flame created in the trough is utilized to heat the trough at its under side to insure a complete combustion, substantially as described.

2. The combination, with a shallow trough to contain the oil in small quantity to be burned and a side wall extended upwardly from the inner edge of the shallow trough, of a deflecting-wall located outside of and extended downward from the outer edge of the trough to form therewith a passage for the products of combustion contiguous to the outer side of the upwardly-extended side wall and through which the products of combustion pass down under and in contact with the bottom and inner side or edge of the said trough, substantially as described.

3. The combination, with a shallow trough to contain the oil in small quantity to be burned and a side wall extended upwardly from the inner edge of the shallow trough, of

[a deflecting-wall located outside of the outer edge of the trough and inclined downward toward the inner edge of the trough to form with the outer edge of the trough a passage for the products of combustion contiguous to the outer side of the upwardly-extended side ing-wall supporting said lugs and forming with the outer edge of the shallow trough a passage for the products of combustion, substantially as described.

5. The combination, with an annular shallow trough to contain the oil in small quantity to be burned, having an annular inside wall extended upwardly from the inner edge of said shallow trough above the outer edge of the same, forming a central outlet-passage for the products of combustion, of an annular deflecting-wall located outside of the outer edge of the trough and inclined downward to form with the outer edge of the trough a passage for the products of combustion, substantially as described.

6. The combination, with a petroleumburner of a valve-casing, provided with an inlet-port connected to an oil-supply and an outlet-port connected to the said burner, an

independent valve for each part, a regulator.

connected to the inlet-valve and operated by the pressure of the boiler, and a regulator connected to the outlet-valve and operated by excess of oil from the burner, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
