T0 FULLER LEHIGH COMPANY, A CORPORATION OF DELAWARE SUPPORT FOR WATER-COOLED WALLS OF BOILERS Application filed. November 20, 1926. Serial No. 149,561.

This invention relates to a support for furnace walls that may be cooled by water sectionpartly broken away, showing an em- ;bodiment ofthe invention; Fig. Q is a section along the line 2-2 of'Fig. I; Fig. 3 is a plan view of one of the supports; Fig. 4 is a section along the line 4-4' of Fig. 3; and Fig. 5 is an end view of thesupport shown in Fig. 3.

In the drawings reference character 1 indicates a furnace of a boiler in the lower portion of which a stoker (not shown) maybe located. A. water tube boiler may be located above the furnace 1 having inclined tubes 2 connected to headers 3-and 4. The other parts of the boiler are not shown in detail. The usual mud drum 5 is shown located below the headers 4.

- steam therein, each successive tfube 7 being madev slightly longer'than the preceding one to accommodate this arrangement of. the header 8. The lower'ends of the-tubes 7are bent outwardly and terminate in a header 9 that is suspended by means of straps 10 from a/support 11 so that the headercan move slightly due to expansion and contraction of thetubes fif. The headers 8 and 9 can be connected-to the water circulation system of the boilerin any convenient manner,- as, I

for example, by pipes connected to the headers 8 and 9.

Supports 15 made in the shape of hollow boxes that ard'fictarigular in cross section and arranged sideiby side are located below the rear wall '6 and support the same, these hollow supports 15 being in turnsupported by means of I-beams 16 extending parallel with the wall 6. The support-s or hollow boxes 15 have their outer ends 17 preferably flush with the outer surface of the wall6 and these outer ends are open to the atmosphere.

The other ends of these boxes are beveleded openings 20 in their upper walls through which tubes 7 extend and are made sufiiciently large to enable the tubes to move as they change in length due to expansion andcontraction.

It will be obvious that the hollow box supports 15 not only support the wall 6 of the furnace, but that they also permit ingress of air into the furnace for combustion purposesand at the same time this air aids in cooling the lower portion of the wall.

I claim:

1. In a furnace, a wall having a row of vertically extending tubes disposed along the inner side thereof and having their lower ends bent outwardly and connected to ,a header disposed outside the wall, and a plurality of boxes disposed beneath said wall and coustructed -to conduct air to the furnace, each of said outwardly bent tube enils )assing through one of said boxes and said Joxes supporting the wall above them.

2. In a furnace, a wall having a row of vertically extending tubes disposed along the inner side thereof and having their lowor? ends bent outwardly and connected to a v header disposed outside the wall, and a plurality of boxes disposed beneath said wall and constructed to conduct air to the furnace, said outwardly bent tube ends assing through said boxes, sai'd'boxes having the upper-edges of their inner-ends substantially flush with the inner side of the wall.

3. In a furnace, a wall having a row of vertically extending tubes disposed along the inner side thereof and having their lowor ends bent outwardly and connected to a header disposed outside the-wall, a plurality of boxes disposed beneath said wall and constructed to conduct air to the furnace said outwardly bentiube ends passing through said boxes, said boxes having the u per edges of their inner ends substantially ush with the inner side of the wall, and said inner ends being inclined downwardly and outwardly from said upper edges.

4. In a furnace, a support having a box disposed thereon, said box having one end disposed within the furnace and inclined downwardly and outwardly, a wall disposed above said box, means for admitting air through the box into the furnace, the outer end of said box being open, a header disposed outside the wall adjacent said open end, and a tube disposed on the inner side of the wall and having its lower end bent outwardly and connected to said header, said outwardly bent end extending through a hole in said box and through the outer end 1 thereof 5. In a furnace, a vertically extending wall, a box disposed beneath said wall and forming a support therefor, avertically extending tube in said wall having its lower end bent outwardly and extending through said box and through openings in the top and outside thereof, a header disposed outside the wall and connected to the tube, and means for passing air through said box into the furnace, said openings being large enough to permit lateral movement of the tubes therein.

6. In a furnace, a wall having a tube adjacent the inner face thereof, aheader dis posed outside the'wall, an end of-the tube being bent outwardly and connected to said header, a box having, openings in one side and the outer end thereof through which said end of the tube passes, and means for passing air through said box into the furnace, said openings being large enough to permit lateral movement of the tubes therein. if
