15 Claims. (Cl. ‘l2-401)
This invention relates to improvements in the such wall, the section being taken on approxi
construction of furnace walls of the type wherein' mately line 2-2 of Fig.> 1;
Fig. 3 is a side elevational view of a slab-re
the furnace chamber wall is formed of refractory

blocks or tiles which are supported on an external
5 metallic framework.
One of the objects vof the present invention is
the provision df an improved construction for
supporting the wall in sections upon the metallic
framework in such fashion that the refractory
10 blocks and tiles which make up the sectionsare
retained in proper position and may be assembled

A particular object is the provision of a con
struction wherein the refractory wall may be
effectively insulated for the purpose of avoiding
2-0 loss of heat, and which is particularly adapted to

An understanding of the invention will be most
quickly had from a detailed explanation of the
construction here illustrated, which will now be

also the removal and replacement of the insula
tion and the wall refractories for purposes of in

VYet another object is the provision of an im
proved construction wherein-an external sheath

metallic framework in such fashion as to consti
tute an effective external covering or ñnish
30 sheathing which may be assembled with facility
and dismounted sectionally to afford access to the
insulation and the wall refractories and the mem
bers whereby they are supported on the metallic
supporting members. ,

For purpose of aiding in an explanation of the
the column members I0 are secured transverse
frame members il, which extend horizontally
from one column member to another. These 25
transverse frame members are made of a suitable
heat resistant material. such as cast iron, and are
provided with top and bottom flanges extending
both inwardly and outwardly, and also with4 an
upwardly extending bracket-retaining flange I Ia.
They are mountedf-on the ilanges Illa of the col
umn members bymeans of bolts I2 which pass
through said iianges, and they are provided with
bolt holes IIb at intervals along their length.

lug 20 contacts one vside of the tile groove and
the lug 2| the opposite side, and thereby the tile

To provide an outside finish sheathing or cas
ing and an insulating dead air space, I employ
a plurality of sheet or plate sections 3l. These
are somewhat wider than the distance between
the flanges Ilia of juxtaposed column members,
and somewhat shorter than the vertical distance
between the bolts i2. For mounting them in
place, I place‘bolts 35 in the bolt holes IIb oi' the
transverse frame members, securing them in
place by nuts 36. The sheet sections 3l are in- y
serted between the`adjacent column members
until their lateral marginal portions come to rest 40
upon the ñanges Illa, their lower margins being`
supported on the bolts 3l. Batten strips 31
which are punched to receive the bolts 3l are then
threaded -thereon in overlapping relationship to
the marginal portions of the adjacent sheet sec
tions 34. Batten clamps 33 are provided, each
being shaped to accommodate the end, portion
2| of one of the brackets, and the groove 26a
of the other tile of the pair being likewise Ven
gaged with those lugs of the adjacent bracket.
