Fred jackson jun. in Bury, Count. Lancaster, Engl. Sealing for flues from steam boilers.

Addendum to patent 346438.

Patented in the German Empire on June 21, 1922. Longest duration: March 23, 1935.

The subject of the invention relates to a seal for the fire puffs of Steam boilers that have inner pulls as well as side and girders.

In the case of the boiler design in question, which has already been described in patent 346438 plates are attached to the rear end of the kettle, and plates can also be attached to the front on both sides of the kettle At the end of the same, similar plates

be brought, which engage in slots in the masonry to escape the hot gases in the fox at the rear end of the boiler and the inflow of cold air at the front end on both sides of the Avoid boiler, the sealing plates are arranged in such a way that they the Take thermal expansion of the boiler into account.

According to the invention, the masonry is connected at the front end and at the rear end of the boiler by longitudinal and cross bars. These are inserted into the joints of the brickwork. The longitudinal bars take up almost the full length of the wall structure or the partition wall. and the cross bars extend from one side to the other of the partition wall and go through the slots or elongated holes in the sealing plates which are attached to the boiler wall. ^;

The subject of the invention is shown in the drawing; the figures mean: i Fig. Ι a front view of the boiler: the right side move is shown in section,

Fig. 2 is a top view according to Fig. 1; both side moves are shown in longitudinal section. Fig. 3 is a sectional rear view of the boiler, '

Fig. 4 is a top view according to Fig. 3, from which the arrangement of the partition walls to guide the flue gases into the fox at the rear end of the boiler.

Fig. 5 shows in section and in an enlarged view the partition wall P at the rear end of the boiler.

Fig. 6 is a cross section corresponding to Fig. 5.

The boiler A can be an ordinary whale boiler and carries plates B fastened to the boiler bottom by means of the angle iron b . At the front end of the boiler A , the plates C are fastened on both sides by means of angle iron c. All plates B, C are provided with elongated holes b ' and c' , respectively. The puffs of fire at the rear end of the boiler are closed by the partition walls /) and those at the front end of the boiler by partition walls E. The partition walls D are provided with notches d which engage in the panels B located on the rear linden of the boiler , while the partition walls E located at the front end have notches e into which the panels C are inserted. F denotes locking slides, with the help of which the side pulls (/ * can be blocked from the trigger to the fox for the purpose of regulating the passage to the latter (which is not shown in the drawing).

The reinforcements H , which are composed of longitudinal bars h and cross bars ti , are also built into the partition walls D and C , so that the masonry, i.e. the partition walls D and E, are given a special reinforcement. The longitudinal bars /; are arranged on both sides of the partition walls in question and extend in the masonry beyond the end of the slots d and e. The cross bars ti connect the mentioned longitudinal bars h and hold them firmly in their position to one another. One of the aforementioned cross bars ti passes through an elongated hole b ' or c, which are located in the plates B and C. A U-iron K is arranged on the rear boiler floor above the hall) of the plates B. A second profile iron M of right-angled cross-section is walled into the masonry in such a way that the hanging flange engages in the aforementioned U-iron K , the space remaining in the same being filled with asbestos powder or similar fillers for the purpose of expansion of the boiler or contraction when it cools down.

For the same reasons, the slots d, e are filled with the same packing or fillers.
