14' Claims.

This invention relates'to furnace arch nosing and involves the general type of rocking suspension disclosed in my application for patent-filed October- 193 5,- Serial No; 46,702; but constiii tutes an" improvement thereon by'providing for adjustablylimiting the'rocking movement of the suspension'brackets in one direction so that the same bracket-may be used for amultiplicityof arch andwall combinations without more'than two tile shapes, namely a and" a nosing tile:

Another object ofthe'invention is wedge to provide a nosing suspension of such type that it will automatically accommodate itself transversely of the furnace, the brackets being freelyv sliding andpendantly supported from-a beam or thejlike,

bridging the furnace forthesupport of the nosing.

A" further object of theinvention is to provide it being possible to-rep1ace any them the nosing by displacement only of the tiles singly or in pairs of that particular vertical row'.

With the general objects named in "View and others as will hereinafter appear, the invention consists in certain novel and useful features of order" that front wall, said arch andv wall being connected by a nosing construction-embodying. theinven'e tion.

Figure '2 is a,.section on the line II--II of=Figure 1,. with the two uppermost nosing. tile and their hangers removed from position. Figure 3 is an enlarged top plan viewof: a

supporting bracket embodying the invention.

Figure t is a side elevation of the shown in Figure 2; V I

Figure 5 is an enlarged elevation hanger embodying the invention.

bracket as of 'a tile Figures 8 to 11- inclusive arefragmental end views of transverse supporting beams, each. illustrating different combinations between arches, nosings and walls, which may be formed with thetile bracket and hanger of the invention.

Figure 12 is a fragmental side elevation of the abutment end of the bracket shown in Figure 4, as'itzmay beconstructed for adjustably maintainingthe angle of the bracket to suit the arch and wall angles to be joined.

In the said drawings, where like reference characters identify corresponding parts in all of the figures, I represents a supporting beam for the nosing, arch and wall; As shown in Figure 1, a series of arch supports 2 are carried by hangers fromsaid' beam and suspended in spaced relation from the supports 2 are a series of .hangers 3 which detachably carry roof tile 4, at their lower ends.. Mounted on top of the beam I are verticalbuck-stays 5 to whichhorizontal tile hangers 5a are secured for detachably engaging the rear faces of wall tiles or blocks 6.

In the construction as shown in the present embodiment of the invention, a channel iron 1 underlies and is secured to the beam l, and hooked over a flange thereof for free rocking suspension and longitudinal sliding movement, are sector-like brackets 8 arranged in spaced relation for the full width of the furnace, one bracket coming between each pair of sidewise abutting nosing tile, as illustrated herein. The upper" ends of the brackets 8 terminate in open suspension hooks 9-, and the body of the brackets adjacent the hooks have an abutment-leg l9 adapted for contact with the underside of the supporting-member l. I

' If desired, the upper end of'the leg Ii! may becylindrical as at II, and such cylindrical portion may be threaded as at 2! (Figure 12), to receive an adjustable abutment nut 22. By providing for adjusting the angle, it will be apparent that the bracket is of universal character and that a nosing may be producedas shown in Figures 8 to 11 to suit varying relationships between arches and walls without a plurality of differently shaped wedge nosing tile.

Projecting from: opposite-sides of the sectorlike' bracket 8 and in' arcuaterelation to each other, are a series of spaced lugs or studs [2 to detachably receive-tile hangers. The tile hangers of the invention comprise body or flange portions I3, which at their upper ends, terminate in a pair of spaced hooks M, the distance between said hooks being such as to receive the flat body portion of the bracket 8 and permit the hooks to engage the opposite studs 12 of said bracket for rocking movement thereon. The radial projection of the brackets to prevent their unimpeded downward rocking and possible detachment of their hooks from the studs, is guarded against through contact of abutment portions Ma on the hangers with the front edge of the bracket 8 as illustrated. Formed integrally with the flat body portion [3 of the hanger and projecting in opposite directions therefrom, are two sets of flanges l5 and I6, the flanges l5 being received within notches l1 formed in the reduced outer'end l8 of wedge-shaped nosing tile 19. ,Each hanger engages with a pair of tile, as the devices are here illustrated, the flange l5 preventing movement of the tile inward into the furnace, and the flange i6 preventing movement of the tile nosing downwardly around the circumference of the curve established by the arcuate relationship of the parts so that there shall be no overloading of the underlying tile. It will also be evident that instead of having each hanger engage a pair of tile, the tile may be formed with T-shaped slots for receiving the flange l5, so that each hanger shall individually support a single tile instead of sup-porting the opposite sides of a pair of tile.

With a nosing construction of the invention it will be evident that the transverse arch support may be a continuous bridging member and does not have to be specially formed or fabricated for the support of nosing brackets at predetermined distances apart. Thus with the present construction the entire nosing may shift to one side or the other, transversely of the furnace, to accommodate any unusual expansion conditions which may arise. In addition to thus accommodating lateral expansion of the nosing, the brackets of the invention are free to swing or rock on the transverse support to accommodate longitudinal expansion of the arch. Each hanger is also free for limited upward rocking movement around the axis of its supporting studs. With the construction shown and described it will be further noted that the uppermost nosing tile may support bricks or the like forming an offset expansion joint 23 underlying the wall. It has been found that by individually locking each nosing tile against unlimited downward movement around the curvature established by the nosing, the construction possesses the advantage of protecting or avoiding overloads applied to the lowermost tile, or the possible unthreading or detaching of all of the tile due to an arch or nosing failure which sometimes occurs when there is no stop member.

From the above description it will be apparent that I have produced a construction which embodies all of the features of advantage set forth as desirable and while I have described and illustrated the preferred embodiment of the invention, it is to be understood that I reserve the right to all changes falling within the spirit of the invention and without the ambit of the prior art.
