FURNOE ARCE.

Application led may 31, 1919. y Serial No. 301,024.

l and I do hereby declare the following to be form of 1beams, exten a full, clear, and exact description of the invention, such as will enable others skilled in the artvto which -it appertains to make and use the same.

My invention relates to re arches for boilers or steam generating plants, and has yfor its object to improve the same in the several particulars hereinafter disclosed. Generally stated, the invention consis'ts of the novel devices and combinationsl of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Fig. 1 is a perspective view with some parts removed and some parts broken away, illustrating the improved arch and showin the rear portion thereof;

Fig. 2 is a fragmentary view in side elevation illustrating the manner in which the laterally spaced beam and beam tips are hung from the main beams of the arch;

Flg. 2a is an elevation looking at the parts shown in Fi 2 ina direction from the right toward the left, in respect to said Fig. 2;

Fig. 3 is a section taken through a portion of the arch, some parts being removed;

Fig. et is a perspective view ofcone of the main arch blocks; Y y

`Fi 4 is a view corresponding to Fig. 4,

but s owingthe form of block used to. re place the former in making repairs.;

Fig. 5 is a perspective' view showlng one section of one of the supplemental blocks;

Fig. Gis a perspective view of one of thel main corner blocks;

Fi 7 is a perspective View of one ofthe lsupp emental corner blocks; and

Fig. 8 is a perspective view of one 'of the corner filler blocks.

The furnace arch will occupy the usual .position between masonry walls 9. Main arch supporting beams 10, the rear one of which is shown 1n the drawin s, preferably in the d transversel of the arch from one wall 9 to the other. multiing up er plicity of laterally spaced forwardly and rearwardly extended beams 11 are located below and hung from the main beams 10 in a manner presently to be noted. These beams 11 are also preferable I-beams, but their lower flanges are preferably turned slightly downward so that they convergein an upward direction. Only one of the main beams 10 is shown in thedrawings, but the second main beam, not shown, would be located above the outer end portions of the beams 11. At their inner ends, the beams, 11 are provided with upstanding T-shaped necks 12. For each beam 11 there is a short beam herein called a detachable beam tip 11a. These beam tips 11EL have the same cross sectional form as the beams 11, and at their rear ends, are provided with upstanding T-shaped webs 12 that correspond in cross section to the webs 12. The T- shaped webs 12 and 12a of the beams 11 and beamv tips 11 ride upon and are interlocked with T-shaped channels formed in the underside ofthe bracket-like beam hangers 13, which beam hangers are channeled on their upper faces for interlocking sliding engagement with the lower anges of the overlying main beams. By thebeam hangers 13, therefore, the beams 11 and the beam tips 11a are detachably and independently hung from the main beams, inasmuch as either` of the webs 12 or 12 may be slid from position without disturbing the other.

The main arch formin blocks 14 shown in Figs. 1, 3 and 4 haveheavy rectangular lower portions which, when the blocks are assembled, form the undersurface of fire exposed surface of the ymain portion of the arch, but they are' provided with reduced upper neck ortions Maand with outstandanges 14". vThe fianges 14b are adapte to overlap and rest upon the upper flanges of the beams 11 and to thereby su-pport the main blocks with large clearance etween the up er neck portions of the said blocks and said laterally spaced beams 11'. To protect the lower portions of the beams 11 from the re, even if one or more of the main blocks should be burned awaypor broken, I kprovide supplemental blocks The main block shown inFig. 4; and at the left in `F ig. 3, is adapted to replace the main block 14 that has been broken and dropped from position, or has been burned away. This replacing block 16 has a base or lower portion like the block 14 and has a reduced neck portion 16, but instead of forming the flanges 14h projecting transversely of the block, is provided with longitudinally projecting flanges 16b that are adapted to be passed upward through the space between adjacent supplemental blocks.

This replacing block can therefore be pushed upward to position in the arch from beneath, and when it is in position, it is adapted to be hung from the upper flanges of the beams 11 by short metal bars 17 applied to the ulper flanges of said beams and under t e anges 16b of the said blocks 16.

This form of replacing blocks makes it unnecessary to slide a number of the main blocks from position in order to replace a block at any portion of the arch.

The main corner block 18, shown in detail y in Fig. 6', but also shown .in Fig. 1, has a neck portion 18a and upper edge flanges-18b corresponding to the parts v14a and 14h ofthe blocks 14, and which adapt the said main corner blocks to be hung on `the upper flanges of the `beam extensions 11B, with the inner ends of said blocks projecting beyond the inner ends of the said beam tips. The lower portions of these main corner blocks 18 are` shown as narrower than the lower ortions of the main blocks 14 and the spacing between the same is, in the construction illustrated, arranged to be closed up by corner filler blocks 19. These iller blocks 19 have upper flanges 19 that rest upon outstanding ledges 18 of the blocks 18.

The supplemental blocks 20, in their main cross section, are like the supplemental blocks 15, that is, they are made in sections and the sections have channels adapting them to be hung on the lower flanges of the beam tips 11a, but the said channels terminate short of the inner ends of the inner eX'- posed ends of the block sections 20, so that the solid ends of the said block sections protect the ends of the beam tips, as best shown in :F i 1.

A re arch constructed las described, is notonly highly ecient and has a very long life, but may be very Y quickly and easily` erected in the first place, and may be rapidly and cheaply repaired. i

What I claim is: e J1.. A fire arch comprising laterally spaced beams, main blocks hun from saidl beams and forming the under re ex o sed surface of the arch, said main blocks aving channele'd sides, and supplemental blocks located in the channeled side of said main blocks and hung from and protecting the lower portions of said beams independent of said main blocks.
