   Schnitt   nach A-B in Fig. 1, während Fig. 3 einen solchen nach   ('-1) darstellt.   



   In der Wand   der Yorschhtsstür a   sind   wagerechte     Schtitzo b vorgesehen, die   an einem Ende kreisförmig erweitert sind, um die Putzbürste einführen zu können. Die untere Kante des Schlitzes b ist an den den Heizrohren gegenüberstehenden Stellen mit Ausschnitten c versehen, in welchen die in Fig. 1 durch den strichpunktierten Querschnitts-   umriss   angedeutete Stange d der   Pntzbürste   Auflage findet. Zur Erzielung einer besseren   Führung   sind an der den Feuerrohren zugekehrten Seite der   Türe   a Winkeleisen e be-

   An der Stole, wo sich die kreisförmige Erweiterung des Schlitzes b befindet, trägt der Schlitzrahmen f einen Stutzen l, welcher durch eine ebenfalls infolge ihres Eigengewichtes selbsttätig in die   Schliessstellung   gelangende Klappe m abgeschlossen wird. 



   Sollen die   Fouerrohre   des Kessels gereinigt werden, so braucht nur die Klappe m gehoben zu werden, um die Putzbürste einführen zu können, worauf das erste Rohr aus-

   Section along A-B in Fig. 1, while Fig. 3 shows such a section along ('-1).



   In the wall of the Yorschhtsstür a horizontal Schtitzo b are provided, which are expanded circularly at one end in order to be able to introduce the cleaning brush. The lower edge of the slot b is provided with cutouts c at the points opposite the heating pipes, in which the rod d of the Pntz brush, indicated by the dash-dotted cross-sectional outline in FIG. 1, is supported. To achieve better guidance, angle irons e are placed on the side of the door facing the fire pipes

 overlaps the beveled edge of the adjacent flaps i, so that when the rods with the flap i are moved, the adjacent flaps are also lifted.

   At the stole where the circular widening of the slot b is located, the slot frame f carries a connecting piece l, which is closed by a flap m which also automatically moves into the closed position due to its own weight.



   If the boiler's Fouer pipes are to be cleaned, the flap m only needs to be lifted to insert the cleaning brush, whereupon the first pipe is removed.

Claims

PATENT CLAIM Device to enable the cleaning of the smoke tubes of steam boilers during operation without allowing large amounts of air to penetrate the flues, characterized by a second locking door located behind the usual lock door, which corresponds to the individual rows of fire tubes on one End for the purpose of retracting the cleaning brush has circularly widened, horizontal slots, the lower edge of which has a recess serving as a support for the brush handle opposite each smoke pipe and which slots are covered by a series of overlapping flaps, the side edges of which are beveled,

that the flaps, which remain in the closed position due to their own weight, are automatically lifted as soon as the brush rod exerts lateral pressure on one of its inclined edges. EMI2.2
