STOVE HOOD Filed June 4. 1928 2 Sheets-Sheet 2 11V Vli/V TOR Loyd i/Qay ATTORNEY Patented Get. 22, 1929 UNITED STATES PATENT OFFICE LOYD W. BAY, OF WICI'IITA, KANSAS, ASSIGNOR- TO THE WHITE CASTLE SYSTEM, INC., A CUBPORATION OF KANSAS STOVE HOOD Application filed. June 4, 1928. Serial No. 282,831.

This invention relates to hoods for stoves for carrying 11' the vapors so as to avoid having obnoxious odors or smoke in the room in which the stove is located. 113 is particularly designed for use in connection with a stove or hot plate such as is used in hamburger stands and the like and provision is made for separating the grease from the vapors as well as to carry oil hot air from underneath the hot plate.

The novelty of the invention will be apparcut by reference to the following description in connection with the accompanying drawings in which Fig. 1 is a perspective view of a stove or hot plate to which my invention is applied, parts being broken away to illustrate the burners.

Fig. 2 is a diagrammatic sectional view through the hood and exhauster.

Fig. 3 is a cross-sectional View through the hood and Fig. 4 is an enlarged fragmentary perspective view of the exhauster showing part of the exhauster fan.

The stove frame 1 may be of any preferred construction provided with a hot plate 2 with the usual burners 3 and 4E supplied with gas through a pipe 5 provided with a valve 6, there being regulating valves 7 and 8 for the burners 3 and a. This is all old construction. Mounted upon the top of the stove 1 is a hood consisting of the back wall 9, the end walls 10 and 11, the top 12 and an overhanging front flange 13 relatively narrow in width to provide an open front 14 so that access can he had to the hot plate immediately below the top 12 of the hood. At the end of the hood is a dome shaped portion 15 communicating with a pipe 16 which enters the end of the drum 1'? of the exhauster 18. The drum or housing 1'? carries a circular flange 19 to which the pipe 16 may be attached. Rotata bly mounted in the drum or housing 17 is a cylindrical fan 20 having a shaft 21 connected to the motor 22 whereby the fan can be driven. The bottom portion of the drum or housing has its metal struck-up to provide slots 23 and 23 communicating with a space at below the housing in which is located a drawer or receptacle 25 to catch the grease,

the air passing out to atmosphere through the duct 2 When the food is placed on the hot plate, the grease will vaporize, but it will be drawn up through the hood into the housing and be discharged through the duct 26 ot' the exhauster. The rapidly rotating fan will cool the grease of the vapor throwing it against the wall of the housing where it will flow.

hot plate. Therefore, the heated air will be.

carried off so that the zone about the stove will be relatively cool, this being an important feature because the hot plates or stoves are usually installed in relatively small buildings or rooms so that unless provision was made for carrying oil the heat, the temperature in the room might become objectionably high. 3y separating the grease from the vapors before it passes through the duct 26, the grease will. not pass out to atmosphere but may be. salvaged if desired.

From the foregoing it will be apparent that the device may be easily installed and that it will adequately take care of the hot air generated by or about the stove.

What I claim and desire to secure by Letters-Patent is 1. A vapor receiving hood for stoves comprising a hollow structure having an open front, an air duct admitting atmosphere from the back oi the structure to the interior thereof, an exhauster, a pipe leading from the hood to the exhauster and a grease separator 1n the exhauster.

2. A vapor receiving hood for stoves com 3. A vapor receiving hood for stoves comprising a hollow structure, an exhauster comprising a housing, a fan in the housing, openings in the bottom of the housing, a grease trap below the openings, an air duct leading from the exhauster to atmosphere and a pipe communicating the hood with the exhauster.

4. In combination with a stove having a hood above the same to receive vapors from the stove, a flange projecting upwardly from the back of the stove and combining with the back of the hood to surround a slot open to atmosphere whereby a current of air will be caused to flow into the hood to carry off the vapors from the stove and an exhauster communicating with the top of the hood.

5. In combination with a stove having a hood above the same to receive vapors from the stove, an eXhauster communicating with the top of the hood, a condensation drip pan communicating with the exhauster and means in rear of the hood for admitting a current of air from the back of the stove up through the hoo'dand into the exhauster.

In testimony whereof I affix my signature.

LOYD W. RAY.
