HARDGROVE, OF BETHLEHEM, PENN- SYLVANIA, ASSIGNORS TO FULLER LEHIGH VANIA, A CORPORATION OF DELAWARE COMPANY, OF FULLERTON, PENNSYL- MEANS FOR RETAINING FURNACE WALL BLOCKS AGAINST TUBES Original application filed October 1927, Serial No. 227,456. Divided and this application filed November '17, 1928.

This invention relates a furnace wall and blocks with means for keeping the furnace wall blocks or tile in firm contact with water wall tubesv located in the furnace wall so as to maintain a good contact for the best heat conduction between the tile and tubes, and yet provide attachment in such a manner that broken or injured blocks-or tile can be removed and replaced by new ones. This is a division of our application Ser. No. 227,456, filed October 20, 1927.

The invention will be understood from the description in connection with the accom panying drawing in which Fig. 1 is a side View partly broken away showlng a port on of the furnace wall and Fig. 2 is a section along the line 2-2 of Fig. 1.

In the drawing reference character 1 indicates water tubes of the furnace wall to which the water wall blocks or tile 2 are attached. Each block or tile 2 is somewhat T-shaped in cross section and is provided with rounded portions or curved surfaces 3flto fit against the tubes, and with an extension 4 that projects beyond the centerlines of the tubes.

Holding members 5 have their ends welded to the tubes 1, as indicated at 6. The members 5' are provided with transverse openings 7 into which wedges 8 may be forced. Plates 9, preferably of resilient material are placed between the holding members 5 and beneath the wedges 8, so that when the-wedges are driven in, the edges thereof, contacting with the upper curved edges 10 of the plates 9, will force the plate toward the tile 2. Packing material 11 may be inserted between the plates 9 and the backs of the tile '2.

Changes and modifications can be made without de artin from the spirit or scope of the invention. is to be understood that where the word tile is used in the specification and claims it is meant to include blocks as well, that may be made entirely of metal, or composite blocks made of metal and refractory material.

' We claim:

1. In a furnace wall, water tubes, tile between said tubes having shoulders curved to fit the tubes, holding members for said tile attached to said tubes and means cooperating Serial No. 320,037.

. rear surface of said tile to press said tile into contact with said tubes.

2. In a furnace wall, water tubes, tile between said tubes having shoulders curved to fit the tubes, holding members for said tile attached to said tubes, and comprising a curved plate extending along the rear of said tile and wedges bearing against said plate to press said tile into contact with said tubes.

In a furnace wall, water tubes, tile between said tubes having shoulders curved to fit the tubes, holding members for said tile attached to said tubes, wedges extending transversely of said tubes through said members to keep said tile in place, and a curved plate extending across the rear surface of said tile with its edges in contactwith said wedges.

4. In a furnace wall, water tubes, tile between said tubes, having curved surfaces and an enlarged portion, said curved surfaces bearing against said tubes and said enlarged portion extending outside of the plane of said tubes, holding members for said tile attached to said tubes, and means comprising a curved plate bearing against saidenlarged portion between said members and tile to press said tile into contact with said tubes.

5. In a furnace wall, water tubes, tile between said tubes having shoulders curved to fit the tubes, holding members for said tile attached to said tubes andmeans cooperating with said holding members, said means comprising a channel-shaped member extending across the rear surface of said tile 'to press said tile into contact with said tubes.
