6 Claims.

My invention relates to an improvement in fuel oil burners, and has for one purpose the provision of improved means for delivering a liquid fuel to a burner.

- Another purpose is the provision of such means which may cooperate with or form part of the hinging or supporting means for a furnace or burner door.

Another purpose is the provision of an im proved fuel supply means for supplying liquid fuel to a burner which is hinged for removal outwardly from a furnace.

Another purpose is the provision of improved means for preventing air locks in liquid fuel supply lines used in connection with bumer doors, hinge burners or the like.

Other purposes will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawing wherein:

Fig. 1 is a horizontal section;

Fig. 2 is a partial front eleva-tion; and

Fig. 3 is a section on an enlarged scale on the line 3--3 of Fig. 2.

Like parts are indicated by like symbols throughout the specification and drawing.

Referring to the drawing, I generally indicates any suitable furnace member, which may be mounted, for example, on any suitable supporting members, legs, or the like, indicated at 2. 3 is a burner door, which may have hinge lugs 4 aligned with xed lugs I on the furnace structure. 6 is an air passage member extending inwardly of the door and in communication with an outer and perfectly closed burner housing 1, within which is an inner burner housing or pot 8, which may have a perforated wall. I illustrate, for example, a plurality of air inlets 8a, which communicate with the space between the sleeves 1 and 8. The sole air inlet for such space is the passage 6 on the door 3, which admits air to support combustion Within the pot or inner sleeve 8. The air is admitted through the apertures 8a, and the heat of combustion in or above the pot vaporizes the fuel which is delivered along the below described liquid fuel passage 22. 8 indicates any suitable top baiile structure for the pot, with a 'central opening I0. It will be understood that the details of the burner itself do not of themselves form part of the present invention. For example, the top baille 9 nay under some circumstances be omitted. What is essential is that the air passage 8 may serve as means for supplying air to the space between the outer derstood that any suitable means, such as the top wall I I, and a bottom wall I2, may be employed for insuring that the air supplied to the space between the members 1 and 8 passes through any suitable apertures in the pot 8, in order to mix with the vaporized hydrocarbons within the pot 8.

I may employ any suitable means for mounting the above described burner structure on the door 3, but the passage member 6 may itself be employed as such a supporting means, and is so shown in Figs. 1 and 2.

I5 indicates any suitable hollow hinge pin which may have a top washer I8, and is herein shown as having an open upper end as at I1. Mounted upon the lower end of the hinge pin I5, and preferably secured against relative movement in relation thereto. is a washer or body I8, into one side of which may be screw-threaded a fuel passage member I8. To it may be secured any suitable fuel pipe 28, herein shown as held by a tapered locking sleeve 2|, the details of which do not of themselves form part of the present invention.

22 is a fuel line extending to a lower portion of the pot 8 and shown as extending inwardly through the air inlet passage 6. It is also provided with an outer end fitting 23, to which may be secured an end of the tube 20. A tapered locking sleeve 24 may be employed. It will thus be understood that any liquid fuel which is delivered to the interior of the hinge pin I5 will pass inwardly through the pipe 20 and the fuel passage 22 to the pot.

28 indicates any suitable float chamber, the details of which do not form part of the present invention. The float chamber may be in communication with a source of liquid fuel, as by a supply pipe 28. 21 indicates any suitable exterior lever or control member for controlling the rate of flow or the level of fuel within the oat chamber 25. 'I'he fuel line 28 extends from the float chamber 25 to the fitting I8. It may be locked in position in any suitable manner, as by the compressible gland 28, located within a screwthreaded downward extension 38 of the fitting I8. 3l is any suitable locking cap screw-threaded upon the exterior of the member 38 and containing the housing and locking member 32 upward- 1y thrust against the gland 28. Thereby a fluid fuel flow connection is provided for delivering a liquid fuel to the interior of the hollow pin I5 and, specifically, to the interior of the fitting I8, from'which it flows along the members I8, 2l and burner housing 1 and the pot 8. It will be un- 55 22 to the burner pot 8. It will be understood that this flow is not interrupted by a movement of the closure or door 3, with the burner, about the axis defined by the hollow hinge pin I5.

It-wl be realized that whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.

The use and operation of my invention are as follows:

Broadly stated, I have combined air venting means for the fuel line with the hollow hinge pin I5. There is relatively little pressure involved, as the highest level of fuel in the float chamber 25 may, for example, be an inch above the level of delivery of the fuel to the burner. In practice air bubbles tend to affect the flow of the fuel, especially where a right angle or sharp angle bend is employed in a fuel pipe. I, therefore, run the fuel from the float chamber 25 directly to the hollow hinge pin or to the fitting I8. The hinge pin thereby performs the triple function of serving as a hinge or pivot for the door 3, of delivering fuel from the float chamber to the burner, and of providing a vent to the atmosphere to prevent air locking, or the like.

Whereas fuel may not actually flow through the hinge I5 proper, the hinge pin I5 and the tting I8 may together be considered as forming a hinge structure which is vented to the atmosphere, as at II, and which serves as means for delivering fuel to the burner, independent of the position of the door or closure 3 on its hinge.

Whereas I have shown fuel as flowing rather through the fitting I8 than through the hinge pin proper, it will be understood that under some circumstances it may be advantageous to have the fuel actually iiow upwardly through the hinge pin, to have it taken off for the burner at a higher level.

I claim:

l. In combination with an outer heater housing, a door, a burner mounted on said door, a hollow hinge pin structure for said door, means for delivering a liquid fuel to said hinge pin structure, and means for delivering said liquid fuel from said hinge pin structure to said burner, the interior of the hinge pin structure being vented to the atmosphere.
