BRASSERT @a l COMPANY, OF CHICAGO, ILLINOIS,A CORPORATION OF ILLINOIS n CHECKER CONSTRUCTION Application led February 9, 1931. Serial No. 514,438.

This invention relates to improvements in the checker construction in regenerators for use in hot blast stoves, open hearths, soaking pits o-r heatingk furnaces and to the regenerativeV systems. This invention particularly applies to the construction of regener-v ators in which smaller areas of openings are used at the bottom than at the top, which renders diicult the problem of supporting the checker column at the bottom due to the smallness of the openings and the intervening walls. The checker column is built up out of tile or individual brick.

rIhe bottom support consists of metallic 4elements which correspond in thickness to the filler brick above and are designed in that fashion in order not to obstruct the checker openings. The employment of these supports necessitates building up the walls in between them of small mitre shape b-rick which are objectionable on account of their small size and number of joints, which cause them to become loose and drop out. In order to do away with these joints and still permit the use of metal supports under the filler brick, I propose to use a brick in the form of a cross made of one piece, either of brick or of metal which will replace the four mitre brick used at present. Or I propose to use a brick or metal tile containing a number of openings tallying with the checker openings and fitting in with the metal supports of the fillers, or the metal support may be cast integral with this brick or metal support.

It is therefore an object of my invention to construct the supporting members for the checker brick and filler brick in substantially H-shaped form and of similar dimensions, whereby the cross bar of' the supporting member serves to support the filler brick and the ends or sides support the checker brick.

It is a further object of my invention to so design the supporting members that the outside contour will conform to the contour of the checker brick supported thereabove, whereby each checker brick rests upon parts of five adjoining supporting members.

Further objects and advantages of my in- Yvention will be more readily apparent and better understood from the vfollowing detailed description taken in connection with the attached drawing, in `which different forms of construction are illustrated.

In the drawing- Figure 1 is a plan View showing the manner of associating and positioning a plurality of supporting members. y

Figure 2 is a detail vertical. section illustrating the manner in 4which the supporting members are associated with the ychecker brick and Hoor tilefmembers.

Figure 3 is a plan view of a single supporting member.

. Figure 4 is `a' side elevation thereof,

Figure 5 is an end view of the supporting member shown in Figure 3, and

Figure 6 is ay plan view of a modified con-` struction of supporting member;

Describing first the form of my invention'.

illustrated in Figuresl to 5, inclusive, it will be understood that vertical columns of checker brick 10 which may bein the form shown ofvoctagonal section, are generally carried directly by the rider tile membersV 11, if ller brick are not employed.. However, iffiller brick are loosely inserted in the vertical flow passages in 'and between these checker brick, itis necessary to employ some form 'of Ysupporting Vmeans therefor.

Previous arrangements employing metal bars have been undesirablesince small pieces ofbrick are required to fill up the spaces and are liable to drop outof pla-ce. i

According to my invention the cross bars whichsupport the illerbrick are made integral with head or end portions which cooperate with adjoining members to prevent displacement when in proper position. .One form of .my filler brick supporting member is illustrated in Figures 1 to. 5, inclusive, and

Vdesignated 12. The supporting member vv12' comprises a cross bar 13 which is diagonally disposed with respect to the flow passage thereabove and is preferably rigidly united with head portions 14. Thus the supportingA member as a whole is substantially H- haped in section. Each ofthe-head portions 1,4V

above. The manner of associating the individual supporting member 12 is clearly illustrated in Figure 1, in which the cross bar members 13 extend in directions parallel with e'each other. In this form it will be apparent that each checker brick seats upon tive adj oining supporting members, or, in other words, upon the two heads of one supporting member and portions of the heads of four adjoining If desirable a lug 15 may be formed integral with the cross bar 13 and extend in an upward direction to cooperate with filler brick 16 supported thereabove and to enable proper positioning of the checker brick. An additional lug 17 may extend from the bot-tom of the cross bar corresponding to the upper lug 15 and serve to properly position and hold the supporting members in place. The supporting members may directly rest upon octagonal tile, vor brick members 18, which, in turn, rest upon the rider tile members 11 or the supporting members may rest directly on the rider tile 11 themselves.

The supporting members may be constructed entirely of cast metal or the cross bar alone may be of metal integrally cast with brick head portions or the entire support may be formed of brick.

Figure 6 illustrates a modification of my invention when ordinary block-shaped checker brick is employed. The supporting member 20 is shown in this form to extend entirely across the checker chamber and may be described as three Z-members integrally united. Thus thermember 20 includes diagonal cross bars 21, metal cross braces 22 and end portions 23. The diagonal members 21 support the liller brick thereabove and the

portions

22 and 23 rest upon the rider tile and carry the checker bric V Y Therefore, in both forms ofmy invention the supporting members areso formed that the flow of gas isV unrestricted and displacement of the supporting members cannot occur. A l

Various modilications may be resorted to without departing fromthe spirit of my invention as expressed in the appended claims.

f 2. A supporting member for checker brick and filler brick comprising a cross baradapted to be positioned diagonally of the ilowpassage through a column of checker brick for supporting filler brick therein and head portions integral with the ends of said cross bar adapted to cooperate with the head portions of additional supporting members to form a substantially level base for supporting co1- umns of checker brick.
