JOHN WOLLANT, OF CLEVELAND, OHIO.

GAS HEATING APPARATUS.

Patented May 8, 1917.

Application filed February 18, 1913, Serial No. 749,144. Renewed April 7, 1917. Serial No. 160,540.

To all whom it may concern:

Be it known that I, JOHN WVOLLANT, a citizen of the United States, residing at Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Gas Heating Apparatus; 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 gas heating appaj ratus, and more particularly to means for heating the cold air, one of the objects of my invention being to provide means for heating the cold air and introducing it to an apartment without its coming into conmeans of the combustion of gases, and by exposing the cold air to the heat generated by this combustion and the hot air gases resulting therefrom.

Other objects of my invention and the particular embodiment by which I have here illustrated the invention willbe better understood by referring to the accompanying drawing and the particular description.

Figure 1 is a section taken through the embodiment of my invention illustrated here.

Fig. 2 is a horizontal section of the embodiment illustrated in Fig. 1, and

Fig. 3 is a plan view of one of the baffle plates.

Referring now to the drawing, at 1 I show a suitable cell or reservoir for the cold air as it is introduced into the main part of the apparatus. This cell is not essential to the invention, but is used in the embodiment illustrated for the convenience it affords. The cold air is introduced through any suitable means, such as a pipe 10, which is connected to the cell 1 at an opening in the top of the cell as shown at 11. The cell is provided with another opening 12, from which a conduit 2 leads through the combustion chamber, which is to be described.-

In the form shown, this conduit is shown cylindrical in form, though any suitably I with suitable openings.

shaped conduit may be employed. This conduit leads through a combustion chamber 5, which is here shown concentric with the conduit and likewise cylindrical, though any suitable form may be employed.

The cell 1 is also provided with openings 100, through which air passes from the cell into spaces between the

walls

16, 20 and 23.

Within the combustion chamber and preferably at the bottom thereof, I show a combustion member, here illustrated as a gas burner 4. This gas burner is preferably annular in form and here surrounds the conduit 2. A pipe 13 enters the burner and the same is provided with a plurality of openings 14 through which the gas escapes. The gases may be mixed before they are introduced to the burner, or air or other suitable gases may be introduced into the combustion chamber to combine with the gas escaping from the burner. Any suitable means may be provided for performing this function.

A plurality of baffle plates 6 are mounted in the chamber 5 above the burner, and preferably substantially parallel to the burner. These baffle plates are preferably mounted equal distances apart as is illustrated in the form shown. The baffle plates are provided In the form illustrated each baflie plate is annular in form and is provided with an opening 8, which is created by cutting away a portion of the annular plate. When mounted in the chamber, these baffle plates are so arranged that the openings are in staggered relation to each other, forming a tortuous passage through the chamber, as indicated by the arrows. This passage may be formed in any desired manner, though I prefer to mount the plates so that the openings of the adjacent plates will be diametrically opposite to each other.

In the embodiment illustrated the diameter of the cylinder inclosing the conduit 3 is greater than that inclosing the chamber 5 and smaller than that formed by the casing 23. It is preferably made concentric with these members and is mounted on the air cell or reservoir.

The baffle plates engage the outer side of the wall of the conduit 2 at their inner periphery 15, and the inside of the wall 16 of the chamber 5 at their outer periphery 17, so that the heat is absorbed from the hot gases and conducted to the wall of the inner conduit and to the inner surface of the wall of the conduit 3, which is also provided for conducting cold air. Ihis conduit is formed around the combustion. chamber, and is shown at 3.' Any suitable means may be provided to admit air to the space between the conduit 3 and the wall 16.. In the form shown I provide'a plurality of openings 100 in the top of the reservoir 1. The wall of conduit 3 is indicated by and the inner wall is the outer wall of the combustion chamber 5. The wall 20 may be corrugated or of any other suitable form. The combustion chamber is provided with an opening 21, through which the products of combustion escape and the combustion chamber and the two said air conduits are surrounded by a casing 23 having hot air fines 24 through which the air escapes after it has been heated. It will be seen that thesefiues. operate as a means for creating a draft through the apparatus and sucking the air through the conduits and exposing it to the combustion chamber. 7

.The baflie plates are not provided through the full length of the chamberib, but only far enough to absorb all the heat from thegases. Above this point'the chamberis free of such plates. The wall 20 likewise is not extended above this point, since the gases are cold above this point, and'it 1s not desired that the air should be drawn over the-- upper part of the wall 16, which will be cool on account of its contact with the gases robbed of the heat by the battle plates and cooled below the temperature of the heated air rising through the space 8. It is not diflicult to calculate the point along the.

walls of the chamber 5, where the temperature of the gases within the chamber will be so reduced thatthe air which is rising in the space 3 will be cooled instead of heated.

About this point the wall 20 ceases, and permits the heated air to withdraw from the Wall 16.

' It will be apparent to those skilled in the art that I have illustrated but a single form Copies of this patent may be obtained for of my invention, simply for the purpose of illustratin the same. Numerous and em tensive'departu-res may be made from the from forms and details without departing the spirit of the invention.

I' claim 2- In combination, a cold air cell, a cold' air pipe leading thereto, a combustion chamber, said chamber being provided with an opening in the top' thereof for the escape of the products of combustion, a circular gas and form a tortuous passage for the products of combustion through the combustion chamber, the baflle plates engagingthe side Walls-of the chamber, a casing surrounding the combustion chamber and the conduit and spaced therefrom to form a passage for the passage of air'fr'om said coldair cell, a second conduit leading through the circular gasburner and the'combustion chamber to conduct cold air therethrough, the inner edgesof said baflie plates resting against said second conduit,and hotair fines leading from the top of'said casing.

In witness whereof, I afiiX my signature in the presence of two witnesses, this 15th day of Feby., 1913.
