FURNACE WALL Original Filed Feb. 23, 1927 2 Sheets-Sheet 1 Patented Dec. 19, 1933 ,UNITED STATES FURNACE WALL Philip Washington Antill, Ridgefield Park, N. J., assignor to American Arch Company, New York, N. Y., a corporation of Delaware Application February 23, 1927, Serial No. 170,202 Renewed February 3, 1933 12 Claims.

This invention relates to furnace walls, and more particularly to a sectional wall construction, and it constitutes an improvement upon-the construction disclosed in my co-pending application No. 152,768, filed December 6th, 1926, issued September 26, 1933 as Patent No. 1,927,909.

It is an object of the present invention to provide an improved wall structure capable of ready installation in sections and of easy renewal as to the sections thereof and as to the individual parts of each section.

A further object of the invention is to provide for proper cooling of the wall and the supporting structure thereof and for the expansion and contraction of the bricks therein, and to minimize injury and destruction thereof.

Still another object of the invention is to reduce the number of parts required in the composition of the wall, as well as to reduce the bulk and weight of certain parts employed, and in general, to simplify, improve, and reduce the cost of, wall structures of the general character disclosed in the aforementioned co-pending application.

The nature of the present invention, and the objects and advantages thereof set forth above, together with others which will occur to those skilled in the art, will be clear from the following description, reference being had to the accompanying drawings, wherein:

Fig. 1 is an elevational view of a portion of the refractory wall, taken from the back, with certain parts broken away;

Fig. 2 is a plan view taken on the line 22 of Fig. 1; and

Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1, with certain parts in elevation, showing the relation of the inner refractory portion of the wall to the outer supporting portion.

Referring to the drawings in general, it will be seen that the complete structure embodies an outer wall or other supporting means 2 having beams or other rigid members 3, and an inner refractory wall 4, built up in sections supported by the hangers 5 preferably from the members 3 of the outer wall 2. The inner wall is composed chiefly of three forms of bricks or blocks, which may for convenience be termed tied or hung block 6, filler block '7, and intermediate block 8, these blocks being laid in courses, every alternate course being composed of intermediate brick and the other courses being of tied brick and filler brick alternating in pairs in the course. The blocks may be provided with grooves 24 on their abutting faces, for the application of a binder or for the insertion of a packing material to form a tight joint, such grooves being shown in Figs. 2 and 3. The weight of the wall section built up as described is taken by the lower course of blocks 9, each of which is supported between two adjacent hangers 5 at the bottom thereof, each end resting in a pocket-like structure formed of a foot 10, the lower part 11 of the main web, and the bracket-like portion 12, of a hanger casting. Each hanger 5 is formed at the top with a slot 13 or other suitable means for engagement with a girder 3, and a shoulder 14 against which the lower end of the superjacent hanger bears (see Fig. 3).

At the top of the wall section a juncture is made with the superjacent section by means of 7 a course of L-bricks l5 and a course of blocks 16, forming a slip-joint with the lower course of blocks 9 of the superjacent section, to allow for expansion and contraction under the influence of the heat in the furnace. A seal of some compressible material 17, such as fire clay or an asbastos compound, may also be employed.

For the lateral support of the bricks in the wall,

I provide the hung and filler blocks with ship-lap joints 18, and the hung blocks with each 19 each having a hole 20. The holes 20 of each pair of hung or tied brick are engaged by the lugs or pins 21 of a tie member 22, which latter comprises upper and lower curved or bent bar portions connected, as by webs 23, to form a single tying unit having two lugs 21 extending upwardly and two extending downwardly so as to hold four hung brick into the wall, the curve or bend in the tying member being arranged so that said member will engage a hanger 5 from the'back.

The hangers and the tie members, considered per se, including various 'detailed features of their form and construction, are fully described and claimed in my co-pending divisional application, Serial No. 680,716,'filed July 17th, 1933.

It will be obvious from the foregoing that the wall may be built up in easily replaceable sections, that expansion is provided for, that cooling air may be freely circulated between the inner and outer walls, that all metallic parts such as the hangers and tie members are protected from the heat of the furnace, that the hung or tied blocks are so disposed that comparatively few of them are required to maintain lateral stability in the wall, that the tie members hold the blocks securely in place laterally while they themselves are naturally positioned vertically by the blocks, and that the number, size, weight and expense, of the tie members has been greatly reduced by my invention.

I claim:-

1. In a wall structure, the combination of a hanger, having a forwardly extending foot, superposed bricks, receiving support from said foot, and a tie member positioned rearwardly of the hanger having brick engaging means extending forwardly thereof.

2. A sectional furnace wall construction comprising, a supporting structure, hangers supported thereby, superposed courses of blocks supported by the hangers, and a tie member engaging a hanger and blocks of alternate courses.

3. A sectional furnace wall construction comprising, a supporting structure, hangers supported thereby, superposed courses of blocks supported by the hangers, and a tie member engaging a hanger and a pair of blocks in each of two alternate courses.

4. A sectional furnace wall construction comprising, a supporting structure, hangers supported thereby, superposed courses of blocks sup ported by the hangers, said courses consisting alternately of tied blocks with filler blocks between them and of intermediate blocks, respectively, and a tie member engaging a hanger and a plurality of tied blocks in each of two courses.

5. In combination, a sectional refractory block furnace wall structure, means of independent support for each section at the outer side thereof, and a tie member embracing an element of the supporting means upon the outer side thereof and having arms extending inwardly to the wall and engaging blocks thereof.

6. In combination, a refractory block furnace wall structure, a substantially vertically extending supporting element therefor at the outer side thereof, and a tie member outwardly bowed to embrace said element and arranged to be movable vertically with respect thereto having adjacent its inner ends means of engagement with blocks of the wall.

'7. In combination, a refractory block furnace wall structure, a substantially vertically extending supporting element therefor at the outer side thereof, and a tie member outwardly bowed to embrace said element having adjacent its inner ends means of engagement with blocks of the wall, said means including substantially vertically extending lugs.

8. In combination, a refractory block furnace Wall structure, a substantially vertically extending supporting element therefor at the outer side thereof, and a tie member outwardly bowed to embrace said element having adjacent its inner ends means of engagement with blocks of the wall, said means including an upwardly extending lug and a downwardly extending lug spaced apart vertically to engage blocks of non-adjacent courses in the wall.

9. In a wall structure, the combination of an outer supporting structure, vertically extending hangers, a brick wall supported sectionally thereby, tie means embracing a hanger and engaging a plurality of bricks, and interengaging irregular joints between bricks of a wall section.

10. A sectional furnace wall construction comprising, a'supporting structure, hangers supported thereby, superposed courses of blocks supported by the hangers, and a tie member engaging a hanger and blocks of non-adjacent courses.

11. In a wall structure, the combination of an outer supporting structure, vertically extending I hangers, a brick wall supported sectionally thereby, each section of the wall comprising a plurality of courses of bricks, and tie means embracing a hanger and being in vertically slidable interengagement with a pair of bricks of a course.

12. In a wall structure, the combination of an outer supporting structure, vertically extending hangers, a brick wall supported sectionally thereby, each section of the wall comprising a plurality of courses of bricks, tie means embracing a hanger and being in vertically slidable interengagement with a pair of bricks-of a. course, and interengaging irregular joints between bricks of a section.
