NOSE-BLOCK BRACKET.

Application filed March 28, 1923. Serial No. 627,648.

T 0 all w horn it may concern Be it known that I, IVIAURICE A. IIorr'r, a citizen of the United States, residing at In dianapolis, in the county of Marion and State of Indiana,have invented a new and useful Nose-Block Bracket,'of which the following is a specification.

My invention relates to improvement in hanger brackets for the tile of furnace arches and particularly to the bracket for supporting thenose blocks, both at the forward and rear end of the furnace arch.

One of the objects of my invent-ion is to provide a hanger bracket which may readily be placed in position, which will support certain of the brick of the curtain wall and which will provide a bracket for supporting the nose block hanger, which will permit the ready insertion of the hanger in position and removal of the hanger without disturbing the brick of the furnace curtain wall end, frontor rear.

Forthe purpose of disclosing my invention I have illustrated one embodiment thereof in the accompanying drawings, in which,

Fig. 1 is a partial sectional view of one.

end of a furnace showing my hanger in position with the nose block supported therefrom Fig-2 is a perspective view, partly broken away, of my improved form of hanger, and Fig. 3 is a perspective view of one form of nose block which is adapted to be used in connection therewith.

In the type of furnace which my invention is particularly applicable for use, there is usually provided a. plurality of supporting beams, either channel orI beams, which are supported by the side walls of the furnace and extend transversely of the furnace above the grate. The arch tile are supported from said beams. In the structure illustrated, I have shown two of such beams, 1 and 2, which are arranged at the rear end of the furnace arch. The beams 1 and 2 provide a supporting means for the hangers 3 of the furnace tile 4. The nose block tile 5 is supported from my improved form of bracket 6, Which in turn is supported from the beam 2 and which also supports a plurality of courses of brick 7, which are arranged in front of, and protect, the beam 2, while the wall or cover tile 8 is supported directly upon the beam. The

gral web 13 extending between the arms 11 and a similar web 14 extending between the arms 9. This web 14 extends forwardly from the base of the arms 9 toward the ends and is well below the top surface 15 of the arms. A hanger receiving slot 16 is formed in the web 14 and the forwardends of the web are provided with up-turned lugsli.

The nose block 5 with a T slot 18 to receive one head 19 of a hanger rod.

In operation the bracket 6 is supported from the I beainQ, thearms l1 fitting over the top'of the I beam with the hooks l2 engaging under the top edge of the beam and the heel of the bracket arms 10 resting on the lower forward flange of the beam, a

notch 20 being formed at this point to re- The hanger 21 being inserted in the slot 18of' ceive the edge of the beam flange.

the nose block is then slipped between the arms 9 and into the notch 16 of the web 14, this notch being wide enough to accommodate the hanger rod 21 but sufiiciently narrow to prevent the head 22 of the rod from passing there between. The-fire brick 7 in front of the beam 2 rest upon-thearms 9 and it will be noted that the web 14 is sufficiently below the surface 15 of the arms 9 hanger head 22 without disturbing the fire brick supported on the bracket. The nose. block 5 at its top front edge is provided with an upwardly extending flange 23 which extends upwardly in front of the supporting bracket and contacts with the bottom of the course of bricks 7 so that the bracket is completely protected from the fire.

I claim as my invention:

1. A nose block supporting bracket for furnace arches comprising a pair of spaced apart arms for receiving and supporting the nose block hanger said arms being constructed on their upper surfaces to receive and support furnace brick and having rearwardly extending hooked arms arranged to fit over and engage a supporting beam of is preferably provided the arch to support said bracket in position.

2. A nose block supporting bracket for furnace arches comprising a pair of substantially horizontal arms formed on their top surfaces to receive and support furnace brick having below the upper surface thereof a web connecting the arms and slotted to receive the nose block hanger and provided with a rearwardly extending hook arm arranged to engage over a supporting beam of a furnace arch.

3. A nose block supporting bracket comprising a substantially Z shaped bracket, the lower arm of said bracket being formed to receive on the upper surface thereof fire brick and slotted to receive the nose block hanger and the upper arm of said bracket being hooked to engage over a supporting beam of the furnace arch.

4. A nose block supporting bracket for furnace arches comprising a pair of substantially vertical parallel spaced-apart members, the lower ends of said members being provided with spaced-apart, forwardly projecting supporting arms having their upper surfaces constructed to receive fire brick and the upper ends of said member being provided with rearwardly extending hook arms arranged to engage over a supporting beam of the furnace arch.

5. A nose block supporting bracket for furnace arches comprising a vertical memher having forwardly extending spaced apart supporting arms, said arms being provided with inwardly extending flanges below the top surface of the arms to receive the nose block hanger and a rearwardly extending hook arm at the upper end of said vertical member for engaging over a supporting beam in the furnace arch said supporting arms having their upper surfaces constructed to receive and support fire brick.

6. The combination with a nose block supporting bracket for furnace arches comprising a pair of spaced-apart arms for receiving and supporting the nose block hanger, having a rearwardly extending hook arranged to fit over and engage a supporting beam of the arch, of fire brick mounted upon and supported by said spaced apart arms and extending upwardly in front of the same and a nose block hung from said bracket and provided at its upper forward end with an upwardly extending flange arranged to project upwardly in front of the front end of the bracket.

7. A nose block supporting bracket for furnace arches comprising a pair of substantially vertical parallel spaced apart members the lower ends of said members being provided with forwardly projecting supporting arms and connected together by an integral web extending between the lower ends of the vertical members and between the. supporting arms, said supporting arms having their upper surfaces constructed to receive and support fire brick, and said web being slotted and below the upper surface of said arms to receive the nose block hanger, and the upper ends of said vertical members being provided with rearwardly extending hook arms arranged go engage over a supporting beam of the mrnace arch.

8. A nose block supporting bracket for furnace arches, comprising a pair of substantially vertical parallel spaced apart members having at their upper end rearwardly extending hook arms for engaging over the supporting beam of the furnace arch and having formed at their lower rear edges a rearwardly extending shoulder arranged to engage and rest upon the lower portion of the supporting beam, said arms at their lower ends being provided with forwardly extending substantially horizontal supporting arms arranged on their upper surfaces to receive and supportthe fire brick and having below said upper surfaces a slotted web connecting the arms and arranged to receive and support the nose block hanger. e

In witness whereof I, MAUmou A. Horr'r, have hereunto set my hand at Indianapolis, Indiana, this 21st day of March, A. D. one thousand nine hundred and twenty three.
