'CLASS 36 d.

AUGUST LEMME in COLOGNE. Chimney top or fan.

Patented in the German Empire on December 7th, 189g.

The present invention has the purpose of smoke repelling and penetration to prevent the sun's rays from entering the chimney and to protect it from rain and dust.

Fig. Ι shows the full view of the attachment, Fig. 2 such in an angular design.

(The dotted lines indicate invisible inner walls.)

Figure 3 is a vertical section through the center.

Figures 4, 5 and 6 are horizontal sections according to AB, CD and EF.

The attachment consists of a hollow cylinder a, which is inserted into the chimney at the bottom and surrounded at the top by a second cylinder b and connected to this by diametrical side walls c in such a way that the space between the two is divided into several compartments d. In these compartments there are inwardly inclined walls i at right angles to the walls c , those above from the inner (a) , below from the outer Cy-. linderwand (b) are only a little removed (see. Fig. 6 and 5). These walls, if joined together, would form a hollow truncated cone. A truncated cone e is placed as a cap on the outer cylinder b; it tightly encloses the former by a cylindrical attachment f , but is removable. Also, this cone e (see Fig. Fig. 4), is divided internally by free-standing, secured to the guard wall e, is k upward to tapered side walls, c are the bottom of the same width accurately on the walls in divisions, which, with compound the lower compartments d form several air shafts. The cap e is open at the top and carries a cover g on rods to protect against dust and rain. This cover g is surrounded by a somewhat protruding, cylindrical jacket h which extends almost to the outer wall of the cone e. This prevents the sun's rays from penetrating and the wind blows violently, while promoting a strong draft.

The latter occurs between the cone e and the jacket h and finds a guide downwards on the wall e. Since, furthermore, the walls k and c prevent it from turning in the top, it must flow downwards, from whichever side it may enter, through one of the existing shafts through the outer part of the compartments d . The penetrating down air flow draws the inside of the wall i along upward, where it finds a 'way. This creates an uninterrupted, reciprocal flow of air that carries the rising smoke both downwards and upwards and, if the device is appropriately positioned elsewhere, also provides excellent ventilation.

The detachability of the upper part enables all parts of the attachment, as well as the chimney can be cleaned well.

Claims (1)

Patent claim: Chimney attachment respectively. Fan, characterized in that in the space between the two cylinders or prisms (a and b) on the one hand by the conical shell (i) is from bottom to top taper and are formed from the bottom upwards widening passage, on the other hand, divisions by radially mounted intermediate walls (c), which in the overlying cap (e) are continued by walls (k) , so that the wind rays penetrating between cap (e) and the attached jacket (h) together with the smoke from the cap (g) located in the jacket (h ) through an or several compartments between the walls (k or c) can be deflected downwards, while in the other compartments between the walls (c or k) an upward flow of smoke and air can take place.
