SOOT AND SPARK COLLECTORv Filed April 8. 1952 JNVENTOR. a f ff JOSEPH smc/msm United States Patent Oce 2,720,851 Patented Oct. 18, 1955 SOOI AND SPARK COLLECTOR Joseph Strunsky, Bronx, N. Y. Application April 8, 1952, Serial No. 281,120 Claims. (Cl. 11G-119) This invention relates to a soot and spark catcher.

It is an object of the present invention to provide a soot and spark catcher for chimneys which may be installed on the top thereof as an attachement and which will collect soot and sparks leaving the chimney without interfering with the basic draft of the chimney.

It is another object of the invention to provide a soot and spark catcher for chimneys comprising a turnable member adapted by the wind to be directed to receive the wind and which is so constructed that the wind will cause the soot or sparks to be delivered beneath a shield of the said member to thereby interrupt the outward movement of the soot and sparks and at the same time allowing the main draft of smoke and gases to rise upwardly therethrough.

Other objects of the invention are to provide a soot and spark catcher for chimneys having the above objects in mind which is of simple construction, inexpensive to manufacture, easy to install upon the chimney, has a minimum number of parts, compact, durable and ellicient in operation.

For other objects and for a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure l is a perspective view of the soot and spark catcher embodying the features of the present invention and mounted on the top of a chimney;

Fig. 2 is a top plan view of the catcher;

Fig. 3 is a transverse sectional view taken generally on line 3 3 of Fig. 2;

Fig. 4 is an enlarged fragmentary sectional view taken generally on line 4 4 of Fig. l.

Referring now to the ligures, represents a base member having a depending skirt portion 11 and a horizontal ange portion 12. The skirt portion is adapted to lit the inner wall of the chimney and the horizontal ange portion 12 rests on the top of the chimney to support the base.

Rising upwardly and outwardly from the center portions of the base and from an annular opening 13 thereof is an annular inclined guide track 14 over which tapered rollers 15 may travel. The outer periphery of this track 14 has a guide ange 16 secured thereto by a plurality of screws 17 circumferentially spaced about the guide track 14. This annular member 16 has an inturned lip 18.

The tapered rollers 15 support an annular ring or carriage 19 having a tapered funnel shape member 20 secured thereto by rivet fasteners 21. The annular member 19 has a downwardly extending ange 22 adjacent its inner periphery and a similar downwardly extending flange 23 adjacent its outer periphery with a lip 24 underlying the lip 18 of the annular guard member 16. The upwardly and outwardly extending portion 14 is braced by bracket formations 25 integral with the horizontal portion 12 and the portion 14.

Extending upwardly from the funnel shape member is a square box formation 26 having one corner cut away both at the top and along two sides, as indicated at 27. The

recess is covered with a wire mesh 28 having side and top portions 29 and 30.

The top, upon being cut away has portions thereof which are rolled down to provide downwardly curved soot collecting and shield portions 31 and 32 under which the soot and heavy spark or ash particles are blown by air entering the corner recess 27 and through the wire mesh thereover as shown in Fig. 1. At the outer ends of the shield portions 31 and 32 are respectively vertically-extending shield portions 31 and 32 that cooperate therewith to collect soot and spark particles. Y

A vane 33 will keep the recess of the box portion 26 angled into the prevailing wind. This vane 33 is secured to the corner of the box portion opposite from the recessed corner and is secured thereto by angle plates 34 and 35 by welding or rivets or in any suitable and conventional manner. A

The sides of the wire mesh are fitted into a channel formation 36 and are secured therein by rivets 37. The channel formation 36 is formed by a double bending of the side portions of the box portion 26. Y

In operation the box portion 26 will be adjusted into the wind by the vane 33 and the annular member 19 will roll upon the inclined or tapered rollers 15 whereby to position the corner recess 27 of the box portion 26 so that it will face the wind. The wind on entering the wire mesh will force the heavy particles of smoke under the turned down portions 31 and 32 where they will be caught and collected and be dropped downwardly therefrom into the chimney and along the two sides thereof away from the main updraught of the chimney. The smoke is accordingly slightly deflected in its upward path and only suiciently to locate the soot and sparks under the shield portions. If the upward draught of the chimney is great, these particles may remain collected at the top of the box portion until the draught has subsided and thereafter they will drop into the chimney and come to rest in the bottom thereof.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by theappended claims.
