This invention relates, generally, to gas range accessories andis more particularly directed to a device adapted to be demountably associated with the flue collar of a gas-cook 5 ing' range for the purpose of covering the open top of such flue and deflecting the waste products of combustion in a downwardl and forwardly direction-whereby their ten hcy to be deposited on to the walls of the kitchen is minimized. 4

It is well recognized that when waste products-of an oven lncluding the waste products of combustion together with steam, vapor and other products of cooking operations 7 are dischar" ed through the flue, they are generall in t e form of greasy, sooty vapor whic if discharged upward y wall of the kitchen, will impinge and be deposited on such wall and on the ceiling.

' Careful housewives are called u on to clean the walls of the kitchen frequent y to remove deposits thus occasioned and these deposits are not .onl unsightly and unsanitary but detrimental y 'afiect paint andenamel fin ishes with which the walls are provided.

This situation has long been recognized and numerous adjuncts have been suggested for disposing of the waste products of the oven so that they will not adhere to the walls of the kitchen. The most common expedient is to fit a; housin on the flue collar and to' provide within this ousing one or more layers or bodies of steel wool which is intended to serve as a screen in order to sift .out theand other foreign matter. These so-calle' steel woolgas and vapor particles of see filters have been uite extensively used, but

are open to the-ob]ection th'at' they have to be,

cleaned from time to time in order to re.- 4ovent clogging or giving ofl of ofiensive ors. The object of, the resent invention is to providea sim le an eflicient. form of construction whic in contradistinction to prior practice, may be seated on the stove top or ex-' tension thereof soas' to overl' the top of the flue. and which device is so s aped or configurated that it willoperate as a deflector to receive the products of-the oven and'to defleet, and discharge them in an'u'pward and to forward direction onto the stove'top. Generally in stove construction, there is'a burner relatively adjacent the flue and when such a burner is in operation, the products of the oven are deflected by the present invention directly on to its burner, so that they are adjacent the or analogous bothersome filters.

thereby consumed. As aresult, there are no greasy or sooty particles permitted to float about the room and deposit upon the walls or ceiling. In some forms of as range, there is no burner immediately adjacent the flue, but even'in such cases, the entire stove will be more or less hotwhen the oven is in operation, so that. when the products of the oven are deflected by the device of this invention,

they will impinge upon-the adjacent part of the stove and be deposited there at a point where they can be readily wiped ofi from time to-time or burned off by subsequent operation of the burners.

In any event, th device of this invention will save the walls and ceilin of the kitchen from so oty and greasy de osits and has the further advantage that t e interior of the 1 device is wholly unencumbered by steel wool An important feature of the present invention resides in the fact that it is so constructed as to cooperate with a wide variety-of flues so that one or two models will serve tofit the flue of any make of gas range. This is importa'nt from a commercial standpoint as the necessity of carryin a large variety of'sizes is entirely eliminate .In this connection it is of importance that the device of this 1nflvention is shaped to seat-or rest directly upon the-top of the stove or an extension thereof, so that its not dependent, as all prior con-' structions are, upon a relatively tight rigid I mounting on a pipe section which must fit drawings illustrate different practical em diments of .the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention. 5

Figure 1 is aside elevation of a flue deflector embod the present invention and ada ted for use with an oval flue. Flgure 2 is'a front elevation of the deflecn tOl. v I i Figure 3 is a plan view thereof. Figures 4, 5 and 6 correspond to Figures 1, 2 an 3, but illustrate the deflector as constructed for use with a circular flue.

Referring to the drawings and more par- 11o K ticularly to Figs. 1 to '3, inclusive, 1 designates the flue collar of a as range which extends above the'top of t e stove 2. This is the usual conventionalstove structure and in these figures the collar is of oval configuration as shown best in Fig. 3. The same general arran ement of stove construction is exor stamping provided with an open bottom with one portion of the under side of the same cut away as shown at 3, so that the forward portion'of the device is in the form of an overhanging deflector lip 4. It will be noted, however, that the cut away part 3 extends backwardly less than half of the depth of the device so that the center of gravity is,-

part 3. As a rerearwardly of the cut awayl sult of. this arrangement, t e device is ada ted to rest in a state of eguilibrium upon t e lower edge'5 as illustrate in Figs 1 and 2.

In Figs. 1, 2 and 3., the device is made of an oval shape. to better cooperate with the oval collar 1 whereas in Figs. 4, 5 and 6 the device is of a generally circular contour with a slight flare to the front. In other words in these latter fi res, the overhanging deflector lip 4" is slig tly flared as shown best in Fig. 6, so

as to we sufiicient capacity to the outlet as woul preclude choking at the deflector mouth.

In both forms of the invention the device ,is ada ted to rest by its own weight upon thetop 0 the stove, in such manner that the device will overliethe collan. Said device is made suflicientlylarge to fit loosely about the collar so as to compensate for collars of widely varying sizes and slightly1 different shapes. However,'to preclude s ifting of the device rearwardly, a leaf spring 6 may be conveniently employed. This spring is secured by means of a rivet 7 to the interior of the device and at the back thereof and is adapted to engage with the inner face of the collar to hold the inner surface of the back wall against the collar and clamp the collar between said surface and the spring. This s ring is found in practice to be thoroughl e cient in holding the device against-ina vertent shijtin'g,.but its structure is such that the device may be readil positioned on or removed fromthe stove w en desired. The device is referabl so shapedas to substantially con orm to t at p'oriton-of the j collar with which it is held in contact by the s ring and it is of suflicient. de th' so that its ownwardly curved deflector 11p will proj well forward of the collar while the cut. a ay 'leave the deflector lip. The

t the stove are ada ted to shell and deflect forwardly and downwardis of sufficient dimensions to allow of a proper .outlet for the products of combustion,

@ thereby deflected forwardly and thence downwardly through the cut away 3 as indicated by the arrows. in Fig. 1 and out through the opening beneath the deflector lip onto the top of the stove or the top of the oven as the case may be.

When the oven is in operation, these parts of the stove are heated to a high degree so that the extraneous matterimpmging on the heated stove parts will adhere thereto and be consumed. This is patricularly true where the outlet to the flue is positioned adjacent an open'burner. In this latter instance the burner will, if in operation, consume all extraneous matters in the exhaust ases as they civics of this invention is preferably made in the form of a casting wherein its weight will be suflicient to firmly maintain it in position. It is durable and embodies no pall'vts that can fail to operate because there are o real movable parts out any cleaning or attention whatsoever as the interior thereof is wholl unencumbered.

. In some forms of the inventlon, the free edge of the deflector lip may bescalloped or other-' wise configured for the purpose of ornamentation, but in the drawings the device is shown perfectly plain in theinterestof clearness. These drawings show the invention in its preferred practical. forms, but the invention is to be understood as fully commensurate with theapple'nded claims.

Havihg thus lly described the invention, what I claim asnew and desire to secure by Letters Patent is:

1. A flue cover and deflector for gas ranges embodying an inverted bowl shaped shell, the major portion of the lower edge of which is flat to permit such flat edge to rest upon the top of a stove in a position to loosely em brace the flue collar thereof, and the forward portion of the lower edge of which shell is cut awa to provide an outlet, the portion of the s ell above which constitutes a forwardl pro'ecting overhangin deflector lip. exten ing orwardly beyond t e flue collar and downwardly into spaced a art relation with the top of the stove where vapors passing outwardl 'thr'ou t e flue of caug t within the ases and away to provide an outlet, the portion of theshell above. which constitutes a forwardly projecting overhanging-deflector lip exten ing forwardly beyond the flue collar and downwardly into'spaced apart relation with the top of the stove, whereby gases and vapors passing outwardly through the flue of the stove are adapted to*be cau ht within the;

shell and deflected'forward y and downrelative thereto.

, w a'rdly thereby and out of the outlet beneath the overhangin deflector lip, and means for clamping the s ell to the flue collar to permit of inadvertent movement of the shell 3. A flue cover and deflector for gas ranges embodying an inverted bowl shaped shell, the major portion of the lower edge of which is flat topermit such flat edge to rest upon a the top of astove in a position to loosely embrace the flue collar thereof, and the. forward portion of the lower edge of which shell is cut away to provide an outlet, the portion of the shellabove which constitutes a forwardly projecting overhangingdeflector lip extending forwardly beyond the flue downwardly into spaced apart relation with the top of the stove whereby gases and vapors passing outwardly through theflue of the stove are adapted to be caught within the shell and deflected forwardly and downwardly thereby and out of the outlet beneath the overhanging deflector lip, and a leaf spring secured lnteriorly of the shell intermediate its top and bottom ofvthe latter and projecting downwardly to substantially the lower edge of the shell, said leaf spring beinmadapted to extend intothe flue to clamp the shell to the collar thereof and preclude inadvertent movement of the shell relative to the collar. 7 In testimony whereof foregoing specification.
