To all whom it may concern:

Be it known that I, KnNioHI ARAKI, a citizen of the United States, residing at Honolulu, in the county of Honolulu and Territor of Hawaii, have invented a new and use 111 Chimney Protector, of which the r as applied to the chimney of the oil burner.

following is a specification.

The present invent on is a protector for the chlmneys of oil stove burners. 2

The principal object of the invention is 'first .to prevent the chimney in cooking stoves from becoming foul or rusting by the overflow of liquids; the dropping and overfiowof grease, etc, during thecooking operation. l

A further objectoi the invention. is the provision of such a protector as above'de scribed having a tra thereon which enlarges the capacity 0 the pan of the protector and whichcan be removed and emptiedfas desired. without necessitating the entire removal of the protector during the cookingoperation. v I

The inventionfurther resides in sundry details and construction and arrangement of parts which will appear as the specification proceeds. i

In drawings, the invention is disclosed in the form in which it is considered to be the best, but the invention is not limited to such form becauseit is capable of being embodied in other forms; and it isto be Fig. 4 is a transverse sectional view taken substantially on line 4.& of Fig. 2.

Fig. 5 is a view similar to Fig. 4; showing a modified form of the'invention, and Fig. 6 is a view similar to Fig. lilluS- trating a further modified; form of the 'invention.

this specification and the annexed Like'characters of reference denote similar and like parts throughout the specifica tion and drawingsj The protector of this invention is partice ularly adapted to be applied to thechimneys of fuel oil burners which are more or less standardized in size and shape, and which consist of a burner portion 1, tubular chimney member 2 surmounting the burner and having transparent doors 3 therein for pur poses well understood. These burners, including their chimneys, may be mounted on a 'i rame 4- having atop or supporting grating 5, or they may be singly constructed to form a single burner or heater of the form well known. The upper end 6 of the chimney 2is usually of a substantially frusto-conical shape and Op nat its extremity. I

The protector 7 takes the form of a circular pan having a circular opening at its center as at 8. The outer edge of the pan is provided with "an upstanding flange 9 and the edge of the opening is provided with a downwardly depending flange 10, which extends into the opening at theend 6 ofthe chimney and has afitting engage mentwith the edge thereof, The bottom wall of the pan 7 has a portion thereof adjacent the opening 8 therein depressed V inwardly of the pan to form the inclined wall 11 which will shed any overflow from a cooking utensil overlying the burner into. the trough 12, the bottomoi which is slightly inclined downwardly toward the traps 13. There may be as many of these traps as desired. vThe traps 13 may be rigidly and permanently secured to the pan 7 as illustrated in 6, or they, be de tachably mountedfas shownin Figs.- 2,. at

and 5 The purpose of the traps'is to enlarge the capacity of the pan for receiving the overflow.

In the cooking of rice andother similar I foods it is preferable and desirableto allow it to boil over in order to effect proper.

cooking according. to the ideas and customs of certainpeoples. Thls continuous oven flow would ordinarily quickly fill the trough 12 of the protector and would necessitate that the vessel containing the food stuff he removed from the fire while-the protector was beingemptied. Therefore, the

traps 13 are provided, and as shown'in Figs. i

and have been made detachable so that opening may beprovided in some instances. On opposite sldes of the openings are ar- I ranged strips 16 spaced slightly from the bottom or underface of the pan and secured thereto in any suitable manner at their ends. The spacing of the strips 16 is suflicient to accommodate the thickness of the projections 14 and to hold the traps tightly against the bottom wall of the pan and in alignment with the openings 15. In this form of the invention as will be seen, that to remove the traps it is only necessary that they be turned slightly, say and the projections 14 will disengage the strips.

In Fig. 5 the traps 13 are'shown as having the same construction as the traps '13 except as to their manner of attachment to the pan 7. In this embodiment the openings 15 are provided at their edges with depend ing flanges formed with a lateral projecting stud which may be stamped therefrom, or

otherwise provided, the depending flanges 17 being adapted to fit to the open end of the traps and the stud 18 to engage into a suitable bayonet slot 19 in theedge of the trap as shown. 7

InFig. 6 the traps 13 are shown as being rigidly and permanently secured to the underfaceof the pan 7 such as by soldering,

welding, or by any other suitable fastening means, or they can be made integral with the pan. These traps 13 are shown as being of larger capacity than the traps 18.

It will readily be seen that from the location and form of the protector of this invention, it is adapted to effectually catch and retain any overflow or wastage that may pass from the utensil in which food stuffs are being cooked and supported above the burner, during the process of cooking, thereby preventing the soiling or rusting of the chimneys and other portions of the stove or burner; and also that provision has been made for collecting the overflow from the pan into traps or pockets which increase the capacity of the protector, and that the traps may be removed and emptied when desired.

Having thus described the invention what sired to secure Letters Patent is: a

1. A protector for chimneys of oil stove burners, comprising a pan having a central opening therein to register with the opening in the upper end of the chimney'and adapted to rest on the upper end of said chimney, and a drain trap in the bottom ofthe panto supplement the capacity of said pan.

2. A protector for chimneys of oil stove burners, comprising a pan to be supported by and rest upon the upper end of said chimneyand having anopeningin the central portion thereof to register with the opening in the upper end of thechilmiey, means about said central opening of thepan to prevent liquid frompassing therethrough when'at a normal level in the" pan, a'drain trap communicating with the bottom offthe pan and removably secured thereto. 1

3. A protector for chimneys for oil stove burners, comprising a pan to be supported by and rest upon the upper end of said chimney and having an opening in the b'ottom thereof to register with the opening in the upper end of the chimney, the bottom of said pan about said opening therein being raised to restrict liquid within the panfrom passing down said chimney, and a cup-like v receptacle depending from the bottom ofthe pan and communicating with the interior of the pan for receiving liquid from said p 4-. A protector, for chimneys for oilstove burners as set forth in claim 3, further characterized by said cup-like receptacle being normally adapted to lie outside of the chimney and being removably secured to said pan. 7

.5.
