4 claims.

My invention relates to an improvement in heaters and has for one purpose the provision oi an improved combustion or radiating drum or member, applicable for example to pot-type oil burners.

Another purpose is to provide a radiating member which may readily be tilted to give access to the burner. Y

Another purpose is to provide such a, member which can readily be removed.

Another purpose is to provide such a member which shall gravitally seal itself in relation, to the burner and also in relation to the flue when it is in operating position.

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. l is a, vertical section;

Fig. 2 is a section on the line 2 2 of Fig. l;

Fig. 3 is a partial vertical section on an enlarged scale; and

Fig. 4 is a section on the line 4-4 of Fig. 3.

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

Referring to the drawing, I generally indicates a base member, herein shown in the form of a drum, having a plurality of supporting elements or legs 2 and a bottom 3, with an air inlet aperture fl. Mounted within the member I is a burner pot-5, having an upwardly concave bottom t, liquid fuel inlet means l, and any suitable means 8 for controlling the ow of liquid fuel to the burner. It will be understood that any suitable control means may be employed, whether automatic or manually operated. I may, for example, use a conventional float chamber.

The drum is provided with a plurality of primary air inlet apertures 9, herein shown as arranged in horizontal rows at different levels. Any suitable means may be' employed for admitting secondary air at or near the top of the bottom. I illustrate. for example, a plurality of larger and more closely spaced air inlets IU.

The pot may be supported, for example, upon a ange or angle ring I I, extending inwardly from the base I, and receiving a top ange I2 outwardly extending from the upper edge of the pot. I3 is any suitable nre ring or upper baille having a central aperture I4. I5 is a hinge bracket upwardly extending adjacent one edge of the top of the base I. Extending from thc opposite side of the'base is a large bracket or structure I6, the upper end of which is secured to any suitable flue member I1. It will be observed that the member I6, Yat

bestos packing 20 may be superposed upon the l fire ring I3.

2l is a combustion drum or radiating element, which may be hinged to the bracket I5. I provide for example a pocket 22, adapted to receive the upper end of a hinge member 23, pivoted to the bracket I5, as at 24. It will be observed that the member 22 is of such height in relation tothe Y member 23 that, when the drum 2i is resting in position, with its lower flange 25 upon the pack- .ing 28,"the member 23 is out of contact with the top of the pocket 22, whereby the weight of the drum is effective gravitally to seal the drum against the packing 20. In other words, I provide a sliding connection between the hinge member 23 and the drum 2l. The structure has the further advantage that, if desired, this sliding connection may be employed to permit the complete removal of the drum 2l bybeing merely lifted upwardly away from the base I and the hinge structure.

The drum 2l is provided with a closed top 26 and 'a iiue connection 21 adapted to engage with its terminal flange 28 the packing I9 associated with the flue I1. It will be understood that the parts are so proportioned that, when the drum 2| is in the full line position of Fig. l, it is gravitally held, not only against the packing 20, but against the packing Ill, whereby the drum is suliiciently tightly sealed from the atmosphere to permit efficient operation. The packing 20 may be omitted, if desired, as shown in Figs. l and 2.

Any suitable observation window 35 may be employed in the drum, the details of which do not form part of the present invention.

It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made Iin 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. Y

The use and operation of my invention are as follows:

No matter how perfect may be the construction of a pot type burner, there are circumstances under which carbon may form. In other words, a pot type burner for liquid hydrocarbons needs to be cleaned from time to time. Also, in lighting such burners, itis customary to drop matches or burning paper upon the bottom 6 of the burner. It is desirable to have ready access to the burner, both for cleaning and if desired for starting.

In the present structure, if desired, the observation window or door V35 may be completely closed. In that event, in starting the burner, the operator may slightlytilt the drum 2l forwardly to or toward the dotted line position of Fig. 1. The lighted match or piece of paper can then beA dropped to the bottom of the pot to ignite the oil delivered through the inlet 1. As soon as the lighted material has been dropped in, the drum vcan bev returned to the full line position, where it will seal itself adequately by gravity.

On the other hand, to get access to the interior of the burner to clean any part thereof, the drlmi 2| can be tilted forwardly and can then be lifted upwardly from the hinge structure and entirely removed from the heater structure. Thus, the user can observe, clean or repair both the burner pot and the drum with a minimum of delay and with a complete freedom from the necessity of releasing any connections.

As is clear for example from Fig. 1, the bracket or support i5 extends partly around the rear .of the burner and is adapted to serve as a shield for projecting heat forwardly into the room and protecting the wall or fuel tank or any other member which is located on the opposite side of the member I6 from the burner.

I claim:y
