JOHN BARNES COMPANY, TION OF ILLINOIS.

OF ROCKFORD, ILLINOIS, A CORPORA- Specification of Letters Patent.

Patented July 24, 1906.

Application filed May 17,1905- Serial No. 260,885-

To all whom it may concern:

Be it known that I, JosEPH P. BARNES, a citizen of the United States, residing at Rockford, in .the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Fire-Arches for Furnaces, of which the following is a specification.

The object of this invention is to construct a fire-arch for furnaces in which each individual brick can be removed without removing the others.-

In the accompanyin drawings, Fi re 1 is a partial lan view of t e fire-arch. ig. 2 is a verticallsection on dotted line a a, Fig. 4. Fig. 3 is a vertical section on dotted line b b, Fig. 4. Fig. 4 is a lengthwise-vertical section. Fig. 5 is an isometrical representation of one end of one of the supporting -,bars. Fig. 6 is an isometrical representation of one end of the supporting-bar. Fig. 7 is an isometrical representation of one of the bricks. The masonry composes the sides, leaving a fire-chamber between them. The masonry supports a cross-bar 1 by its ends 2. This cross-bar has-a hook edge 3. The masonry supports a series of cross-bars 4 by their ends 5. Each cross-bar has a hook edge 6.

I cross-bar 7 has its ends 8 supported b the masonry and is provided with a hook e ge 9. From one face of this cross-bar extends a ledge 10, having its free edge u turned. Braces 11 connect the ledge with t e main portion of the cross-bar.

At Fig. 7 is shown one of the bricks 12, in one face of which is formed a hook 13. A hook 14 is provided with the two curved ends 15 and 16. Each of the bricks 17 is suspended by a hook 14, and each hook is suspended by a link 18,.one end of which enga es the curved end of the hook and the ot er end engaging the hooked edge 3 of the cross-bar 7. he bricks 12 are each suspended by hooks enga ing the hooked edge of the cross-bars 4.

e bricks 19 are suspended by the hooked ledge 10 of the crossbar 7. These bricks when suspended, as shown at Fig. 4, form the fire-arch of a furnace.

If any one brick becomes broken, it can be removed and replaced without removing any of the others.

I claim as my invention 1. A fire-arch for furnaces comprising a series of beams having their lower ed es in single hook form, a series of do'u le-ended ooked links having their hooks facing in the same direction and suspended by one of the hooks in enga ement with the hooked lower edges of the ieams', a series of fire-bricks each having a recessed face in hook form which receive the lower hooked ends of the links.

2. A fire-arch for furnaces comprising a series of beams having their lower edges in single hook form, one of the beams havin a ooked ledge located above its lower en a series of double-ended hooked links having their hooks facing in the same direction an suspended by one of the hooks in engage ment with the hooked lower edges 0 t e beams, a series of fire-bricks each having a recessed face in hook form, which receives the lower hooked ends of the links, and another series of fire-bricks each havin a recessed face in hook form and suspended by the elevated hooked ledge of one of the beams. 3. 'A fire-arch for furnaces comprising a beam havinga lower ed e in sin 1e hook form, a series of double-ends hooke links having their hooks facing in the same direction, a se ries of supplemental double-ended hooked Y .hooks are suspended, and a series of firebricks each having a'recessed face in hook form which receives the lower ends of the first-named hooks.
