DEFLECTOR FOR HEATERS.

SPECIFICATION forming part of Letters Patent N0. 734,071, dated July 21, 1903.

' Application filed May 8, 1901. Serial No. 59,213. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES KOBMANN, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Deflectors for Heaters; 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.

My invention relates to improvements in deflectors for use in connection with steam,

hot-water, and similar heaters. One of its objects is to provide a deflector which will throw the heat out into the room and which will protect the wall from becoming soiled by heated-air currents and materials carried thereby, as well as from excessive heat.

Another object is to provide a deflector which can be ornamented exteriorly without interfering with the smooth interior deflecting surface.

It also consists in certain details of combination, form, and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in Which- Figurel is a front elevation of the deflector. Fig. 2 is a vertical section through the same on line 2' z of Fig. l.

A represents the deflector; B,the heater; 0, In the deflectors heretofore in use, which usually consisted of a single thickness of sheet metal, the heat was transferred by conduction through the deflector, so as to heat the air between the deflector and the wall and also the wall, which caused currents of heated air to rise between the deflector and the wall, and these heatedair currents had the efiect of depositing soot and dust on the-wall in rear of and above the deflector and on the ceiling above the heater. Also where a single thickness of material was employed in the deflector it was impossible to produce relief ornamentation thereon without interfering with its properties as a deflector, because the irregular surfaces would catch and retain the heated air.

I obviate these objections by constructing the deflector with a double wall and providing means for preventing the passage of heat by conduction through the deflector.

E F represent the inner and outer walls be of sheet metal or of a suitable non-conducting material. In order to further prevent the conduction of heat through the deflector, I preferably provide a sheet of nonconducting material J, which may be attached to the inner side of either wall E or F. I also, preferably, provide small openings K near the bottom and top of the deflector,com-

municating with the air-chamber I, whichpermits a limited circulation of air in said air-space, allowing the air in the space between the walls E F to escape as soon as it becomes heated and its place to be taken by cool air from the bottom. The air at an ordinary temperature between the rear wall of the deflector and thecwall of the room will drop to some extent to fill the vacuum otherwise caused by the passing of the cool air adjacent the floor of the room into the interior of the deflector; but the air between the deflector and the wall of the room will not be heated, nor will such movement cause any deposit on the wall of the room.

By constructing the deflector as above described no heated-air currents are formed between the deflector and the wall of the room and the wall is not soiled. By reason of the form of the inner wall E the heat is thrown well out into the room, while the wall F may be suitably ornamented to present a pleasing exterior. 7

Having described my invention, what I claim isr The combination witha radiator or the like, of a deflector which is independent thereof and separately positioned as an entirety between the radiator and the wall of the room,

comprising front and rear walls separated by an airspace and connected at the top and sides, said deflector being provided with perforations at its upper and lower portions, thereby permitting circulation of air through the deflector from the bottom upwardly, and a non-heat-conducting lining within the defiector, said front wall being adapted to throw the heated air out into the room and the rear wail, interior air-space and non-heat-conduct- :0 ing material preventing conduction of the heat to the wall of the room.

In testimony whereoflhaveafiixed my signature in presence of two witnesses.

CHARLES KOBMANN. Witnesses:
