Application md october 2o, 1927. serial No. 227,581.

This invention has reference to a liquid fuel burner especially designed for heating purposes, the primary object ofthe invention being to provide a burner simulating a radiator which may be positioned in a room for heating, the burner being of vthe -wickl less type.

An importantA object of the invention is -to provide a burnerincluding a plurality of horizontally disposed bars formed with longitudinal grooves defining lateral flanges, the ianges being formed with openings deining irregular passageways transverselyof the bars, to insure the heating of the air-to vaporize the oil and produce a iiame simulating a gas flame Another objectof the invention is the provision of means for regulating the blaze so that the device may be eiiclently em.- ployed in connection with a thermostat control device or may be manually operated to regulate the temperature in a'room.

With the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the comination and arrangement of parts and in lthe details of construction hereinafter described andclaimed," it being understood that changes inthe precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departin from the spirit of the invention.

Referring to the drawings: p Figure 1 is a rear elevational view of a heater constructed in accordance with the invention.

Figure 2 is a vertical sectional view through the burner, the radiator section having'been removed.

igure 3 is a fragmental side elevational view ofone of the bars forming the burner block. Figure 4 is a bottom plan view thereof. Figure 5 is a plan view of the burner, the radiator section having been,` removed.

Figure 6 is a sectional view taken on line 6-6 of Figure 5.

Figure 7 isa fragmental sectional View illustrating the liquid feeding tank. l Figure 8 is' an end elevational View of the burner;

Figure 9 is a fragmentary plan view of the fuel trough.

Referrmg to the drawings in detail, the

base of the burner is indicated generally by the reference character 5 and includes supporting legs 6.

The burner proper includes spaced side plates or casing sections indicated at 7, each of which is provided with an upper inwardly extended flange 8 and a lower outwardly extended ange 9, the flanges 9 of the casing sections being formed with openings to receive securing screws 10 that secure the casing section to the base.

The ianges 8 are also provided with bolt openings `to receive'the bolts 11 that are disposed in spaced relation throughout the lengths of the flanges 8. v These bolts 11 also pass through-openings 'formed in the bars 12 to secure .the bars together, the bars 12 being of lengthsequal to the length of the burner casing proper, and as shown, are provided with grooves 13 formed longitudinally thereof and disposed in the lower surfaces.

Openings 14 are` formed in the iianges defined by the grooves, which openings of one flange are arranged in staggered relation with the openings of the adjacent ange so -that air. passing through the burner will take a zig-zag course to insure the heating of the air to vaporize the liquid fuel.

The burner casing is wider than the combined widths of the tiers of bars which are arranged one upon another as clearly shown by Figure 6 so that air passageways 14! are .provided between the outer surfaces of the ars and the casing sections, with the result that air' may pass upwardly into these passageways where it will pass inwardly to the central portion of the burner.

The bars 12 of the respective tiers are disposed in spaced relation ldefining a passageway 15 for the flame of the burner. Supported under the tiers of bars 12 is an elongated fuel trough 16 formed with a 'ange 17 through which the bolts 11 pass to secure the fuel trough in position under the tiers of bars 12.-

At a point intermediate the ends of the trough 16 is\a transversely disposed slot or orifice 18 through which fuel passes as it enters the fuel trough, the slot'being substantially small so that only a small quantity of fuel will ass therethrough.

Secured irectly under the slot or orifice 18 is a fuel chamber 1 9 that communicates seen t at due to this construction, the

fountain chamber 26 ma be moved vertically to change the level o liquid therein and thereby control the passage of fuel from the fuel chamber 19, and consequently regulate the flow of fuel to the fuel trough 16.

A supply tank indicated at 29 and which is in the form of a bottle is inverted and positioned in the fountain chamber 26 so that lwhen the liquid level in the fountain chamber falls below the mouth of the bottle 29, air will pass into the bottle and allow fuel to pass from the bottle to replenish the fuel in the fuel chamber.

This movement of the fuel chamber controls the size of the flame and consequently the 'heating capacity of the burner proper, as it will be seen that should the fountain chamber be lowered so that the level of the liquid u fuel therein stands below the level `of the fuel in the fuel chamber 19, the liquid fuel will cease to flow into the fuel trough, but when the fountain chamber is elevated, to a point to bring the liquid level therein above the liquid level in the fuel chamber, liquid fuel will flow into the fuel chamber and overflow into the fuel trough 16.

Thus it will be obvious that by regulating the fountain chamber, the quantity of fuel consumed may be regulated so that a large or smalll flame will be produced, it being obvious that by this'arrangement of parts, a pilot flame may be provided.

The reference character 30 indicates the control rod that is sup lied with a handle 31 at its forward end to fgcilitate the operation thereof, the inner .end of the 7control rod being formed at right angles where it is connected with the link 32 which in lturn connects with the fountain chamber 26.

A coiled spring 33 is mounted on the control rody 30 and acts to normally hold the control rod in a position against movement. The radiator coils or heat radiating portion of the heater are indicated at 34, to the end fthat heat passing upwardly through the burner will be passed through the radiator coils or tubes to throw ofi1 heat into the room.

A- pipe indicated at 35 acts to carry off fumes which. may be present, due to the burning of the oil, and in connection with this 1pe it might be stated that it is contemp ated to connect this pipe with pipes or flues leadingI to the open air.

The operation of the device is as follows:

Oil enters the trough 16 through the slot or orifice 18 where it is burned, the heat from the blaze heatinv the bars 12 to the end that as air is drawn through the air passageways,

the air which has become heated, vaporizes the liquid fuel causing it to burn rapidly in a blue flame.

While I have shown and described a burner of the wickless typev especially designed for heating purposes, it is to be understood that a burner of this character may be constructed circular in formation to adapty it for cooking purposes.

I claim z.

1. A liquid fuel burner including a base, a

fuel trough supported on the base and having flanges, said fuel trough having a slot to admit fuel to the trough, a burner block including spaced tiers, the space between the tiers constituting a vertical passageway, said tiers being mounted on the flanges, each tier embodying a plurality of superposed bars,

each bar'having a groove formed longitudinally thereof providing parallel flanges having notches formed therein, said notches constituting passageways communicating with the vertical passageway, and a casing forming a part o-f the burner block and spaced from the bars providing lateral passageways communicating with the vertical passageway through the notches.
