To aZZ whom t may concern.'

Be it known that I, Louis V. ZIEGLER, a citizen of the United States, `residing at 97 Highland Place, Ridgefield Park, in the -county of Bergen, State of New Jersey,

have invented certain new and useful Improvements in Separators for Gas-Stoves;

and I do hereby declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Aan attachment for gas stoves and the like having for its object the elimination of greasy vapors` escaping through the outlet flue from, the oven. 1

Commercial gas stoves are commonly pro-l vided with an outlet Hue connected to the oven to carry off the products of combus# tion and the greasy vapors resulting from culinary operations. This flue may be connected to a chimney by a suitable pipe, but

more frequently no chimney or other outlet from the kitchen is available, and in common experience, the stove flue discharges directly into the kitchen. The greasy vapors resulting from broiling and roasting operations in the oven, mix with the combustion products escaping from the burners. The vapors remain in suspension, however, only while the gases are sufficiently heated and are readily deposited upon con tact with a relatively cooler surface. It is usual, therefore, to find a greasy discoloration. on the walll behind the outlet flue, which, because of the character of the de posited material, is removed withdifficulty and is accordingly frequently allowed to remain on the Wall. The grease holds dust particles which come in contact therewith, and the result is an unsightly and unsani tary condition. It is the purpose of the present invention to provide a relatively simple and inexpensive device which will successfully separate the greasy vapor from the combustion gases without affecting the efficiency of the oven thus preventing the deposit above referred to, lightening the housewifes labors and insuring a more sanitary condition of the kitchen.

Further objects and advantages of the invention will be apparent as it is better understood by reference to the following Specication of Letters Patent.

specification whenused in connection with the accompanying preferred embodiment thereof, in which,

Iigure l. is a view in perspective of a gas stove with my device applied thereto;

drawing illustrating the Fig. `2 is a vertical section through one form* of my invention;

Fig. 3 is a section on the line 3 3 of Fig. 2;

Fig. 4 is a vertical section through another and slightly different form of my invention; and

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

1n Figs. 2 and 3 of the drawings I have illustrated a form of my invention which has proven to be eminently satisfactory in accomplishing the desired objects. vice comprises a short pipe section 5 which may beof suitable cross-sectional shape and dimensions to closely The defit the outlet flue 6v of the stove 4. The pipe section 5 may be of any desired length,'this factor being immaterial to the success of the device. Breferably a short section is employed because the appearance of the device is enhanced and it is more readily cleaned.

The free end of the pipe section 5 is by a plate 7 secured theretolvby a strap 7, and an opening or slot 8 is provided in the pipe section forming a restricted outlet through which the gases es cape. The plate 7 is preferably provided with a depending lip 9 spacedl from and disposed in front of the opening or slot 8 in the pipe section 5. In arranging the device on a gas stove the lip 9 is advantageously disposed so that the gases are discharged away from the wall of the room in which the stove is placed.

To insure the separation of the greasy vapor from the gases escaping from the device, I preferably secure a sheet 10 of incombustible fibrous material, such as asbestos, to the inner face of the plate 7 and the slieetmay be perforated as at 1l to increase the exposed surface thereof and to provide lodgment for the greasy particles. The sheet l0 is preferably supported in the device s0 that it may be readily removed for replaceplaced or new sheets ment of the ibrous material. ln the latter Jform of my device, I provide tivo sheets or baffles of

iibrous material

12 and 13 suitably secured to a rectangular trame 14; which may be constructed ot strap-iron, in such a manner that` the resiliency ot the side members 15 thereof causes the trame to be held in adjusted position within the pipe section 5. The trame 14 is, however, readily removable to permit cleaning ot the device. Both of the

sheets

12 and 13 of fibrous Inaterial are provided with perforations 16, the perforations in the lower sheet 13. permitting the passage ot gases therethrough and those in the sheet 12 providing lodgment for the greasy particles as hereinbefore described.

rI`he operation of the device which Jforms a cover for the gas stove flue will be readily understood from the foregoing The gases carrying greasy vapor from the oven escape from the flue to the cover in which their velocity is reduced as they impinge against the asbestos sheet or sheets. The vapors are separated and the gases are deiiected through the opening or .slot 8 against the lip 9. The gases are again de- {iected by the lip and are dissipated in the atmosphere, substantially tree from greasy vapors. rlhe device, moreover, by regulating the escape of gases from the stove, insures a more even temperature in the oven and thus increases the utility ot the stove. Cleaning is readily accomplished by removing the device from the stove and Withdrawing the asbestos sheets 'which may be remay be inserted.

The device is small in size and adds to the appearance of the stove by covering the unsightly flue outlet. It is of 'inexpensive construction throughout' and is obviously capable of advantageous employment for its intended purpose.

Various changes may be made in the form, arrangement and construction of the parts Without departing from the invention or sacrificing any of the material advantages thereof.

I claim:

l. A device for separating greasy vapors from gases escaping through a gas stove Hue, comprising a tubular cover adapted to be applied to the Hue of a gas stove and having an imperforate top, grease absorbent material positioned at the under side of said top, and said cover having an outlet so dis- \posed with respect to said material that the gases are vdeflected through the outlet by im- -pingement on the surface of said material.

2. A device for separating greasy vapors from gases escaping through a gas stove flue, comprising a tubular cover vadapted to be applied to the flue of a gas stove, and having an imperforate top, grease absorbent material positioned at the under side of said top7 said cover having an outlet so disposed with respect to said material that the gases are deflected through the outlet by impingement on the surface of said material, and a lip depending in front of said outlet to again deflect the gases as they pass therethrough.

3.151 device for separating greasy vapors from gases escaping through a gas `stove iue, comprising a tubular cover adapted to be applied to the iue of the gas stove, and having an imperforate top, a transversely disposed removable sheet of grease absorbent material arranged within said cover belovv said top and in the path of said gases, said cover having an outlet for the gases below the-plane of said sheet through which the gases are deflected by impingement on said sheet.

4. A device for separating greasy vapors from gases escaping through a gas stove flue, including a cover for said flue, a plurality of baii'les arranged in the path of said gases Within said cover, and a restricted outlet for said gases belov the plane of the uppermost baiile and laterally disposed with respect to said battles, gases are deflected by impingement on uppermost baiiie.
