PATENT :OFFICE :DETRICK COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS FURNACE CoNs'IRIIC'rIoNv Application `filed May 21,

`This invention relates to furnace linings and particularly to an improved furnace roof construction. The roofs of large furnaces are usually made of or lined-with fire brick or 5 tiles and the supporting of these tiles requires special construction particularly adapted to reliably support but arranged topermit ready removal of the tiles and repair of the walls and roof.v It is the primary object of my inf l@ vention to provide an improved construction of this type which embodies these I several novel features and the several parts of which l are interchangeable and can be readily assembled to provide a'furnace of any size and construction desired.'

As one feature of my invention, I provide the body portion of the roof with a plurality of vllongitudinally extending tile-supporting bars and the Curvednose portion thereof with a plurality of transversely extending tile supporting bars. All these bars are preferably supported transversely extending beams having their ends suitably support-ed 5 as in or on the side walls of the furnace.l I

preferably support the longitudinally extending bars on and beneath the beams by a novel type of removable clamps hereinafter y described. The transversely extendingk bars at the nose or inner end of the furnace are preferably supported on a plurality of nose rackets carried by certain of the beams which may serve also as a curtain wall support. The provision of these several novel features, the construction and advantages of which will be hereinafter fully described, comprises a further object of my invention.

Among other objects of my invention is the provision of various novel features relating to the mounting ofthe tiles on their supporting bars. These features include a novel form of hanger adapted to be readily attached to and detached fromthe bai: by a movement downwardly therefrom upon removaltof a keeperfby which it is retained on the bar.

In the drawings annexedhereto'and formi ing apart of this specification, I have shown certain embodiments of my invention', but it` ewill be understood that the invention can be otherwise embodied and that the drawings 1925. Serial No. 31,737.

Referring'morespecifically to the draw- A ings by reference characters, 1. indicates the side walls of a furnace, 2 the front end wall,

f and 3 the curtain wall. Extending trains- ',versely of the furnace and supported at their ends in the side` walls are aplurality of I-beams-4, 5, and 6, and also two rails or rail-beams 7. A plurality of channel bars '8 on the I-beams support 3f Steel deck cover plate 9. A fuel chute 10 for pulverized fuel is carried by the cover plate and extends downwardly into the furnace. A plurality of nose brackets 11 are bolted to the I-beams and 6 in a position at the rear margin or nose portion of the roof.

' shown in detail in Figs. 5 and 6. Each clamp 15 comprises a'body portion having an upwardly facing lug 16 engaging and supporting the flange 17 of the bar l2 and a downwardly facing lug engaging over the flange 13 or 14. A pair Yof clamps are provided on each side of each beam at` each intersection of the bar and beam. This manner of supporting the bars on the beams permits adjustment of the bars to any positlon desired and the bars are held in such position by bolts 19 extending through each pair of clamps 'and drawing the same into firm engagement with the bar flanges.

M The tiles 20 can be carried on the bar heads 21 in any manner desired. In Figs. l to 4 I have shown the same as carried by a resilient tile-holding clip combined with my detachable connecting and keeper means. As shown best in Fig. 3 this resilientclip comprises an elongated metal sheet 22 having the ends ofthe twosides thereof bent to one side of the sheet and curved into tile groove engaging members 23 which normally spring toward each other in a manner to snap into opposed grooves 24 in the tiles 20. As illusltrated in the drawings, the clip is prefer-A ably made longl enough to hold several tiles.

The opposite slde of each clip carries a pair of' spaced jaws 25 with an intervening channel for receiving the bar head or ila-nge 21.

When the lugs are over the bar head a pair of keepers 26 are slid longitudinally into position between the aws and bar head and serve to hold the clip and tiles to the head. Each-keeper 26 is provided with allug 27 .for aiding in its insertion and removal and adapted to engage in ra'notch in the jaw to retain the keeper against longitudinal displacementrelative thereto. This keeper arran ement is 'also illustrated in Fig. 14 hereina er described.

The form of furnace nose construction shown in Figs. 1, 3, 4 and 7 includes a plurality of tile-supporting bars 28 extending transversely of the furnace. These bars are supported on the nose bracket 11 at different elevations, being secured by bolted clamps as best seen in Fig. 1. The nose tile supporting clips 29, as illustrated in Figsvl and 3, are` like the resilient clips 22 except that the bar engaging portions thereof compriseV a supporting flange 30 engageable over the upper side of the bar head, the clips 29 being also bent outward at 31 to co-operate with the liange 30 in supporting the clips and tiles on the bar. 4

While each nose tile 32 may be of sufficient vWidth to l'ill a clip, I preferably form them Vmetrical projection 36 in alignment therewith across thelremainin portion of such face. Anytwo such bloc s are readily assembled and held in such position by the co-engagement of` the projections and grooves. Furthermore, the blocks being duplicates, only one type of block need be manufactured and kept in stock, which of course considerably cheapens and simplifies the same.

lThe nose brackets 11 and the co-operating members 5 and 6 not yonly serve to support the nose of the roof but they also serve to support the curtain wall 3.. The upper portion of each nose bracket comprises a flat supporting surface 37, and an I-beam 38 is mounted on these surfaces parallel with the beam 6, the beam 38 being of a size to bring its top surface level with the top surface of the beam 6. The beam 38 is held in place by clamps 39. "The surface 37 is provided with an integral laterally extending lug 40 which is adapted to engage over one flange of the beam 38 when a very large beam is used, it being understood that the size of beam 38 used necessarily varies with the size of the beam 6. A portion of the curtain Wall 3 is supported on fire brick 41 mounted on the beams 6 and 38 as illustrated in Fig. 1.

A plurality. of wall supporting brackets 42 are bolted to the web of beam 6, these brackets preferablybeing spaced about eighteen inches apart. As illustrated, the opposite sides of each bracket are provided with integral lugs or shoulders 43 adapted to receive and support the ends of shelf bars 44 therein. illustrated in Figs. 2 and 3, two such shelf bars are suspended between each two adjacent brackets and these shelf bars, in conjunction with the fire brick 41, serve to support the curtain Wall 3. Each bracket 42 is preferably provided witha hole 45 therethrough co-operating with a hole 46 through the curtain Wall whereby 'cool air may enter to keep the bracket cool.

It should be understood'that my invention Acontemplates afurnace roof composed of sectional parts so standardized that the same parts can be used in forming furnace roofs and walls of various designs. In Fig. 4 I have shown a slightly modified form of roof, several of the parts of which are Athe same as those illustrated in Figs. 1, 2, and 3. The parts which are the same as those in Figs. 1,2, and 3 are designated by the same reference characters.

In the construction shown in Fig. 4, transversely extending I- beams 47, 48, 49, 50, and

51 and a rail beam 52 form the roof-support-l plurality of `nose brackets 53 are supported on I-beams and 51, the curtain wall 3 being supported on fire brick 41 on the I- beam 51 and a plate 54 on the nose brackets, anden shelf bars 44 carried on brackets 42 as in Fig. 1. The nose tile 32 are supported from the nose bracket in the same manner as described in reference to Fig. 1.

The curved tile' supporting bars 55 of Fig. 4 are hung from I-beams 48 and a transverse member 56 mounted on thenose brackets 53, clamps beingused for supporting the bars. rllhe tiles 20, 57 and 58 are hung from the bars by my improved tile-supporting clips which are described in reference to Fig. 1.

It will be seen that the tiles 20 can be readily removed for repair by removing the keeper 26 and dropping the tiles downward. I also preferably form the tiles 57 ,and 58 of the concave portion of the roof of a shape to be readily removed in like manner. It will be noted thatthe tiles 57 are formed with the front and rear sides thereof converging downwardly while certain of the adjacent tiles 58 are formed with parallel front and rear sides or at least with the outer end thereof of no greater dimension than the inner In Figs. 7, and 9 I have illustrated theV tiles as supported'on the bars by means other than thejresilient lclips l29heretofore described. The bar supporting structure of Fig. l

7 is the same as. that shownv in Fig. 1 and is designated by the same reference characters.

In this arrangement the nose tiles -73'are each provided with a T--slot 74 through the middle portion ofthe outer end thereof. I

, have illustrated `three rows of tiles 73 which are supported on hangers 75 engaging loosely in the T-slots as shown. These -hangers can beof any length and support as many tiles as desu-ed. The hangers may be supported on spacci' members 76, the inner face of each of which is provided with a pair of hooks 77 for engaging over the upper edge of the heads of the 'supporting bars 28. A lug 78 is also formed on each spacer member 76 for assisting in holding the member in place. A pair of flanges 79 is provided on the sides of the member 76 for each hanger to be supported and each hanger is provided with a pair of hook flanges 80 on the web portion thereof for engaging with the flanges 79.

.This construction forms an effective support for the nose permitting its being easily assembled and disassembled. The hangers 75 can be formed of any desired length to accommodate a furnace of any size, as many of such hangers can be provided as desirable, and the members 76` can be provided with a corresponding number of hangers supporting flanges thereon. These several parts may therefore be standardized in a manner to be used in furnaces of varying sizes and designs.

' The horizontal tiles 81 as shown in Figs. 7 and 14 are each formed with a T-slot 82 in the outer end thereof, like the T-slot 74 in tiles 75. The tile-supporting member 83 is preferably elongated to provide a T-head 84 engaging in the T-slots of several tiles strung thereon. The upper portion 85 of this member is elongatedpreferably in a direct-ion at A right angles-to the T-head 84 and is provided with jaws 88 separated by a bar Areceiving channel 86. Keepers 87 when slid into the channel between the bar head 21 and the jaws 88 support the member 83 and tiles on the bar 12. This keeper method of supporting the tiles on the rail 12 is substantially the same that illustrated in Figs. 1 to 4 and heretofore described. The keepers 87 are each provided with a lug 89 thereon for aiding in their placing and removal and for engaging a notch in the jawto hold the keeper against shifting longitudinally relative thereto.

.In Figs. 10 to 13 I have shown a still further modilied form of my invention. In this construction the nose portion of the roof is supported on an I-beam 91 extending transverselyv of the furnace and having its ends suitably supported. The cover plate 9, rails 12 and horizontal tiles 81 are supported on the beam in the same manner as indicated in Fig. 7 and just described.

In this construction I provide the nose brackets supporting members 92 each having a curtain wall supporting arm 93 preferably integral therewith and a recess 94 there-4 in for receiving the bottom flange 95 of the beam 91. The portion of the member adjacent the recess has a Wide overhanging bearing surface 96 and a hook 97 for engaging the flange 95 as illustrated in Fig. 17. Another wide bearing surface 98 (Fig. 11) is provided along the beams. ,f

on the member for engaging the head of the.

being limited by the engagement of the bearing surface 98 with the rail 12.

The nose tiles 73 are supported on hangers 75, the same as in Fig. 7, except that these hangers are supported directly op flanges 99 ofthe member 92. This construction eliminates the use of bars 28 and members 76 shown in Fig. 14. The supporting of. the curtainl wall 3 in this construction yis substantially the same as heretofore described,- the shelf bars 44 being supported on the brackets 93. This construction is exceedingly simple and eliminates the necessity for drilling and bolting and permits free adjustment of the various parts to any position It is believed that the construction andk use of myinvention will be clearly undervstood without further description herein.

`The invention relates particularly to furnace `roof construction wherein are combined beams, bars, rails and other co-operating structure of 3a like nature. It is very obvious that beams, rails, bars,`etc., are all similar in construction and one is ordinarily the equivalent of and can be substituted for the other without modifying or impairing the general furnace construction. I wish it clear- X ly understood, therefore, that throughout this specification and claims these terms and terms of a like nature .are not used in a lim'- ited sense, but are intended 'to cover any equivalent construction. la

It will of course be understood that any of the various forms of my invention can be used and substituted for other rvforms illustrated in the drawings; for example, the

straight furnace wall or roof blocks 20 and 8,1

can'be made in two duplicate -half sections in the same manner as the segmental half sections of blocks shownin Fig. 17 instead of making the blocks as independent units as .shown in Figs. 4 and 14.
