5 Claims. (Cl. 110-99) This invention relates to industrial furnaces and has for its primary object to provide suspension mean for a plurality of parallel rows of pipe or similar supports or rods for the support of furnace nosings and the like. The arrangement is such that the entire erection can be made from within the furnace in most limited or confined areas and the metal parts are largely outside the refractories in a free air area for efficient cooling.

Another object of the invention is to produce a construction of the general character mentioned having tile supports or hangers of hook or J-shape, adapted to be hung on the pipe in reversed pairs, if desired. With this arrangement the hangers can be oscillated to support two or more rows of tile from the same pipe, and thus make it possible to turn a nosing with less overhead metal work than is commonly employed in installations of this nature. If desired, the tile can be made of various materials and supported in zebra of checker-work fashion.

A further object of the invention is to produce a construction in which the tile hangers are 50 positioned that they are free for rocking movement around the pipe and at the same time may shift longitudinally of the pipe. With this type of construction it will be evident that the support lends itself to use with a multiplicity of materials of varying expansion characteristics,

such as high alumina refractory, silica tile, or metal encased basic brick. The rocking and longitudinal shifting of the hangers also permits the same supporting structure to be used with tile of larger or smaller dimensions in any direction.

Another object of the invention is to provide a construction in which the nosing may be installed entirely from within the furnace and short pipe lengths with expansion joints between the same, may be used where it is impossible to thread long pipe lengths except through the end walls of the furnace.

With the general objects named in view and others as will hereinafter appear, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which:

Figure 1 is a fragmental perspective view of a furnace nosing embodying the invention.

Figure 2 is an exploded view of parts of the assembly to more clearly illustrate the construction.

Figure 3 is a fragmental perspective view of a modified construction.

Figure 4 is a view of a construction embodying the U-shaped tile hangers instead of the J-shape shown in the other figures.

In the said drawings, where like reference characters identify corresponding parts in all of the figures, I is a girder or the like of a furnace, and secured thereto in any suitable manner is an arcuate casting 2. By preference, the casting is formed with a right angular pair of ears 3 so that it may be attached to a horizontal or vertical part of the furnace framework, The arcuate flange 4 of the casting is preferably provided with pairs of spaced oppositely projecting pintles 5.

The pipe engaging members are in the form of flanged loops 6, in the preferred construction, as shown in Figures 1 and 2, having their webs i formed with a pair of small openings 8 to engage the pintles, and large openings 9 for engagement with the pipe l0. At their upper ends the loops '6 are offset as at H to form an arcuate stop shoulder l2 which will abut the arcuate face 4 of the casting 2 and prevent oscillation of the member around the pintle. By preference, the web "I of the hangers is also provided with an opening 13 to receive bolts I4, whereby the loops may be clamped in pairs and separation or detachment from the pintles is avoided.

After the loops have been slipped on the pipe in opposed pairs, the parts are bolted in position as above indicated. Adapted to be rockingly supported from the pipe in the preferred construction are J or hook-shaped tile hangers l5. The hangers may be loosely slipped on the pipe in pairs, if desired, with their fiat flanged faces IS in abutment. The lower ends of the hangers have T or other suitable heads I! to engage companion sockets in the tile 18. In order that the tile may be hung in uniform fashion so that the joints may be in alinement, said hangers it may be gradually offset or inclined to maintain the center line of the heads [1 in a plane passing through the abutting faces l6 of said hangers. Of course, if desired the hangers 15 need not be used in pairs, but may be individually hung as required to break vertical or alined joints. With the arrangement described it will be evident that the rows of tile may be separated by expansion joints at any desired point since each hanger is freely oscillating on its respective pipe.

In Figure 3 a modified construction is shown in which the pipe loops are made integral as shown at l 9. In this arrangement the ends of the loops are bifurcated as at 20, and the loops and part I4 have openings 21 which are brought into alinement to receive securing bolts 22.

With a nosing support of the character described and shown, it will be apparent, see Figure 1, that only three pipes are needed to support at least six rows of tile. It wil also be evident that all of the metal work is outside the refractorie where it is exposed on all sides to cooling air which may be circulated around the supports and between the refractories and girders.

As a modification of the J-hanger, the U -shaped hangers 25 of Figure 4 may be used to support tile or refractory. Thi hanger may be used where advantageous.

From the above description, it will be apparent that I have produced a construction embodying all of the features of advantage set forth as desirable, and While I have described and illustrated the preferred embodiment, I reserve the right to all changes within the spirit and scope of the appended claims.

I claim:

1. In a furnace nosing, the combination of a support, having a vertically disposed flange formed with oppositely projecting horizontally extending pintles, a pair of pipe supporting loops engaging opposite sides of said flange and suspended from the pintles with the axes of the loops in alignment and parallel to the longitudinal axi of the pintles, means to clamp the loops against separation, a horizontal pipe carried by the loops, a tile hanger suspended from the pipe at one end and tile hung from the opposite end of said hanger.

2. In a furnace, a pipe support, a horizontal pipe carried by said support, and hangers having hook ends engaging and suspended from the horizontal pipe in abutting pairs, each pair of hangers having their lower ends formed with oifset tile-engaging ears projecting equal distances in opposite directions, the abutting faces of the hook ends and the median point of the ears lying in a common plane.

3. In a furnace nosing, a support, an arcuate casting carried by the support and having spaced oppositely projecting horizontally disposed pintles, pipe loops fitted in pairs against opposite sides of the castings and engaged with the pintles, the axes of said loops being in alinement and parallel to the longitudinal axis of the pintles and each loop having a stop shoulder to abut the casting to limit oscillation of the loop on the pintles, bolts securing the pairs of loops against displacement, parallel rows of horizontal pipe carried by the loops, tile hangers having hook ends engaged with the pipe, and tile suspended from the opposite ends of said hangers.

l. The combination in a furnace, of a beam spanning the furnace, a plurality of castings secured to the beam in spaced relation and in longitudinal alinement, each casting having a plurality of loop-supporting means in paced arcuate relation, pipe-supporting loops carried by the loop-supporting means of the castings, the axes of the corresponding loops supported by adjacent castings being in alinement and parallel to and spaced from the beam, a plurality of rows of pipe carried by the loops in parallel relation to and spaced from the beam, a plurality of spaced tile hangers suspended at one end from the pipe, and nosing tile carried by the other end of said hangers.

5. The combination in a furnace, of a beam spanning the furnace, a plurality of castings secured to the beam in spaced relation and in longitudinal alinement, each casting having a, plurality of loop-supporting means in spaced arcuate relation, pipe-supporting loops carried by the loop-supporting means of the castings, the axes of the corresponding loops supported by adjacent castings being in alinement and parallel to and spaced from the beam, a plurality of rows of pipe carried by the loops in parallel relation to and spaced from the beam, a plurality of spaced tile hangers supported by and freely oscillating at one end from the pipe, and nosing tile carried by the other end of saidhangers.
