APPARATUS FOR PRODUCING COMBUSTION.

SPECIFICATION forming part of Letters Patent No. 556,281, dated March 10, 1896.

' Application filed January 14:, 1896. Serial No. 575,485. (No model.)

To all whom it may concern:

Be it known that 1, PAUL J. SoHLIoHT, a citizen of the United States, residing at Summit, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Apparatus for Producing Oombustion, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part hereof.

My invention relates to means for carrying out the improved method of producing combustion described in my earlier application, Serial No. 523,782, and its object is to provide an efficient and economical apparatus for introducing the air or other supporter of combustion into the chimney or stack and directing it toward the place of combustion, so as to cause it to flow thereto in contact with the hot products of combustion escapin g therefrom.

My invention consists broadly in the com bination, with a chimney or stack or other flue through which the products of combustion escape, of means for causing a current of air or other suitable supporter of combustion to move downward within said chimney or stack to the place of combustion so as to come in contact with the hot products of combustion escaping through said chimney or stack and a wind-guard for protecting the air-current from the external currents or gusts of wind.

My invention also consists in the combination, with a chimney or "stack or other flue through which the products of combustion escape, of a deflector situated in or upon the stack and adapted to produce a current of air or other suitable supporter of combustion in the stack in a direction opposite to the direction of motion of the products of combustion and to separate the initial portion of such current from the products of combustion and a wind-guard for protecting said current from the external currents or gusts of wind.

My invention also consists in the combination, with a chimney or stack or other flue through which the products of combustion escape, of a deflector conforming to the shape of the same, but smaller in size than the chimney or stack, so as to leave a space between it and the chimney or stack, and having a flange extending over the top of the chimney or stack and down the outside thereof, so as to form a wind-guard, whereby the air is caused to flow between the flange and the chimney or stack and into the latter and down toward the place of combustion in contact with the hot products of combustion, and the air-current is protected from external wind gusts or currents.

My invention also consists in certain other features of construction and combinations of parts hereinafter described and claimed.

My invention is fully shown in the accompanying drawings, in which Figure 1 is a perspective sectional view, and Fig. 2 is a top or plan view thereof.

Referring to the drawings, a is an ordinary annular stack.

1) is a deflector. It is annular in shape, thus conforming to the shape of the stack, but is smaller in size than the latter, as a result of which there is a space or passage between the deflector and the stack for the admission of the air. The length of the deflector may be varied according to the distance which the deflector is to extend into the stack; but in every case the deflector is made to extend only a part of the distance toward the place of combustion, so that the air is brought into contact with the hot products of combustion escaping through the stack. The size of the passage between the deflector and the stack can be varied'according to circumstances. Generally it will not do to reduce the outlet for the combustion products to less than half the area of the stack. In most cases the area of such outlet should be muchgreater than the area of the air-passage.

c is a wind-guard connected with the upper end of the deflector. It is preferably formed by bending the end of the deflector over so as to form a flange. This flange is annular in shape and extends over the top of the stack and down the outside thereof far enough to prevent the wind from blowing directly down into the passage between the deflector and the stack, and thus to guard or protect the air-current in such passage from the force or violence of the external gusts or currents of air.

(1d are supporting devices adapted to rest 011 the top of the stack. Any suitable form of supporting devices may be employed.

The operation is as follows: The current of air enters the passage between the wind-guard and the stack in the direction indicated by the arrows e e and flows through the same and over the top edge of the stack and is directed and guided downward by the deflector I). The initial portion of the air-current which is thus caused to move downward in the stack is separated from the products of combustion by the deflector. At the lower end of the deflector the air-current comes in contact with the hot products of combustion escaping through the stack in the direction indicated by the arrows f f. The air continues to flow downward and passes to the place of combustion, while the combustion products continue to flow in the other direction, the two being in contact and the air thereby absorbing heat from the combustion products, and the two currents or columns being mutually aifected and regulated, as fully explained in my earlier application, Serial No. 523,782. The current of air is in the general form of an annular column surrounding or encircling the hot stream of combustion products. There is consequently an extended contact between the descending air and the ascending products which secures the highest efliciency in the production and regulation of the combustion.

In the drawings I have shown my preferred form of deflector and wind-guard. It will be apparent, however, that these parts may be greatly varied in shape and construction. It will also be apparent that the form and character of the stack or chimney or flue can be varied in any manner desired. Thus the stack may be square or rectangular or pol gonal, or may be of brick instead of metal. The shape of the deflector and windguard could be correspondingly varied.

The deflector and wind-guard can be made of any suitable material. Any other suitable supporter of combustion may be used instead of air.

I do not herein claim the deflector alone or the deflector and wind-guard as a separate article of manufacture, as I have included such claims in my other application, Serial No. 575,489.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination with achimney orstack of means for causing a current of air to move downward within said chimney or stack in contact with the products of combustion, and

a wind-guard adapted to protect said current from the wind, substantially as set forth.

2. The combination with a chimney or stack of means for initiating a d0wnWardly-moving current of air within said chimney or stack so that it will flow downward in contact with the products of combustion, and a wind-guard adapted to protect said current from the wind, substantially as set forth.

3. The combination with a chimney or stack, of a deflector situated in or upon the stack, and adapted to produce an air-current in the stack in a direction opposite to the direction of motion of the products of combustion and to separate the initial portion of such air-current from the products of combustion, and a wind-guard adapted to protect said current from the wind, substantially as set forth.

4.. The combination with a chimney or stack, of a deflector conforming to the shape of the same but smaller in size than the chimney or stack so as to leave a space between it and the chimney or stack and extending only a part of the distance toward the place of combustion, and a windguard adapted to the shape of the deflector, substantially as set forth.

5. The combination with a chimney or stack, of a deflector conforming to the shape of the same but smaller in size than the chimney or stack so as to leave a space between it and the chimney or stack and extending only a part of the distance toward the place of combustion the said deflector having a flange ex tending over the top of the chimney or stack and down the outside thereof so as to form a wind-guard, substantially as set forth.

6. The combination with achimney orstack of an annular deflector smaller in. size than the chimney or stack and extending only a part of the distance toward the place of combustion, the said deflector having an annular flange extending over the top of the chimney or stack and down the outside thereof, so as to form a wind-guard, substantially as set forth.

7. The combination witha chimneyorstack of the deflector Z) provided with the windguard a, substantially as set forth.

8. The combination with a chimney or stack of the deflector I), provided with the wind guard c and the supporting devices (Z (Z, substantially as set forth.
