Application led December 31, 1923. Serial No. 683,810.
My invention relates to certain improvements llncmeans for retaining the bricks of y a furnace arch in position. The object of the invention is to so design the bricks and the means for supporting the bricks that repairs can be made without drawing the fire of the furnace.
In the accompanying drawings, Fig. 1 is a longitudinal sectional View of a boiler furnace illustrating my invention; Fig. 2 is a. transverse sectional view on the line 2,-2, Fig. l; V
- Fig. 3 is an enlarged sectional view of the arch shown in Fig. 1;
Fig. 4 is a sectional view on the line 4-4,
Fig. 3;
Fig. 5 is an enlarged sectional viewillustating the means for retainingthe bricks at the front of the furnace;
Figs. 6 and 7 are views of the bricks com posing the main arch;
Figs. 8 and 9 are views of the tapered bricks of the inner curved section;
Figs. 10, 11 and 12 are views of the bricks of the front section;
Fig. 13 is a perspective view of one of the retaining hooks;
Fig. 14 is a perspective view of one of the bars carrying the main arch; and
Fig. 15 is a perspective view of oneV of the plates to which the front bricks are attached. I
1 is the .lire box of a boilerpfurnace. 2 are the tubes of the boiler. 3 is the grate. 4 is the front' of the furnace. 51s a fuel feeder of any type.l 6-6 are transverse overhead beams from which the main arch 7 of the furnace is hung. 8-8 are transverse beams which carry the front` section 9. is protected and need not be renewed. Hooked to the lower portions of the beams 6-6 are a series of bars 11, shown in Fig. 14. These bars have permanent hooks 12 and removable hooks 13 which engage the beams. I e
0n each bar is a longitudinal rib 14 and at one end of eachbar is a curved rib 15.
' The ribs have beveled' upper surfaces as 50 shown in Figs. 4 and 13. Suspended from ythe ribs 14 are hooks 16, the heads 17 o f the hooks are undercut so as to engage the beveled surface of the ribs. At the lower end of each hook is an arm 18 at right Aangles to the head 17. The arms are round in cross section, in the present instance, and
10 is a fixed section of brick work which extend into holes 19. in the bricks 20, Figs, 6 and 7. The bricks are recessed at 21 to bricks to have a certain movementpn the arms in order that they may be 'properly accommodate the hooks 16 and to allow the located in the archi7. When the bricks 20 I 11 and lift it up with the brick, another brick can be placed on the hook and inserted n position without disturbing the furnace The bricks 22 that form the curved inner portion of the `arch are connected by hooks 23 to the curved rib 15, the hooks being made in the same manner as the hooks 16 only shorter.
At the front ofthe furnace are a series of plates 24 made as shown in Fig. 15. The plates -have ribs 25 and a series of projecting lugs 26. The plates are partly. embedded in the front wall of the furnace as shown in Fig. 1.' At the upper end of each plate are recesses 27 to receive the lower anges of the beams 8-8. Wedges 28 are ldriven between the beams and plates Vretaining the plates in position.
At the lower end of each plate `is a rib 29 beveled on its upper surface. Hooks 30 similar to the hooks 16 engage the ribs and have arms which extend into opening 31 in thebricks 32.
The first brick in the series is grooved at 33 in one face so as to engage a ribbed plate 34 secured to the front .of. the furnace. By the above construction, one brick after I claim:
another can be set in place from the top.
1. The combination ina furnace, of two overhead transverse beams having lower ianges; a series of detachable bars; hooks on said bars engaging the lower flanges of said beams, one hook of each set beingdetachable, each bar having a longitudinal iange, said ange having a beveled upper surface; a series of bricks forming the body of the. arch. said bricks being spaced a considerable distance from the bar so that they can be removed without removing the bars, each brick having a recess and a hole in .one side; and long hooks having undercut heads engaging the anges of the bars and having arms extending into the holes in the bricks, the body of the hooks the arch, the first bricks of the series havl0 being located in the recesses in the bricks. ing recesses therein; a 'ribbed bar on 'the 2. The combination in a furnace, of overfurnace structure shaped to fit the bricks; l head beams; a' series of plates hung from hooks engaging the flan es ofthe plates and the beams, said plates having flanges at the tapered bricks; bricks forming the main one side, and curved flanges at their lower bod of the arch; and means for supporting l ends, the side flanges being embedded in the the ricks from above. brick Work of the furnace; a series of tapered bricks forming a curved portion of LYNFORD HAMILTON.
