I Claim. (01. 220-40) My invention relates :to an improvement in pot type liquid hydrocarbon burners and has for one purpose the provision of an improved connecting means between the pot of such a burner and the baflle thereof.

Another purpose is the provision of means for holding the top baflie of such a pot flrmly in position normally, while permitting" its ready removal.

Another purpose is the-provision of improved means for assembling a pot and the 'bafile of a pot type burner.

Other purposes will appear from time to time in the course of thespeciflcation and claim.

I illustrate my invention more or less diagrams matically in the accompanying drawings where- Fig. 1 is a vertical axial section through the no Fig. 2 is a similar section through-the baffle ring on an enlarged scale;

'Fig. 3 is a plan view on an the baflle ring shown in Fig. 2;

Fig. 4. is a plan view of the 1; and

Fig.5 is a section on the line 5-5 of. Fig. 4.

structure of Fig. I

Spot-welded or otherwise secured to the flange 6 of the burner or pot I illustrate a pair of oppositely spaced clips 20, each such clip having a portion 2| engaging and secured to the member 6, an upstanding portion 22, and a clip portion 23 with a downward ofiset or bend 2i intermediate its ends.

The ring 8 may be laid on the top of the pot with the lower face of theportion 9 engaging the upper face of the lip orflange 6 of the pot. The ring may then be rotated about its axis,

" and suchrotation may be employed to cause small vertical lugs or bosses H to snap into the clip and seat in the space between the downward offset 24 and the upstanding portion 22. The

' result is a locking action s'ufliciently firm to hold enlarged scale of Like parts are indicated by like characters throughout the specification and drawings.

Referring to the drawings, I generally indicates a cylindrical or slightly conic pot wall having a bottom 2, herein shown as integral, and a plurality of primary air inlet apertures 3. 4 indi- 1 cates a top row of secondary air apertures more closely spaced than the primary .air apertures 3. 3 indicates any suitableconnection for a liquid fuel inlet.

The upper edge of the pot is outwardly flanged as at 8 with a downwardly extending circumferential lip or flange I. 8 generally indicates anupwardly and inwardly extending conic baflle bodyhaving an outer flange 9 and a connecting offset portion l0. As-will be 'clear from Fig. 2, there are two flanges 9, each such flange having anupwardly extending end boss II at one end thereof. As the flange extends about the periphery of the ring from said boss it decreases successively in width until it terminates at a point I! which is of minimum widt l3 indicates a recess between each reduced end I! of-one of said flanges and the enlarged end and boss H of the opposite flange. 1

the ring in place while permitting its easy removal, simply by twisting in the reverse direction, in the event that'removal is necessary.

vMy invention sembly oi the parts, in shipment or at the point of use, and permits ready removal of the ring for replacement, cleaning orthe like.

It will 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 my drawings to be takenas in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.

I claim:

In combination, a pot shaped receptacle havturned portions adapted to snap over said lugs,

the width of the ring flange varying from a maximum at each said lug to a minimum adjacent the next lug.
