To all whom t may concern.'
Be it known that I, GEORGE W. I-IorMANN, a citizen of the United States, residing at Chicago, inthe county of Cook and'State of Illinois, have inventedcertain new and useful Improvements in Heat-Resisting Rails, of which the following is a specification. v
The invention disclosed herein relates to furnace rails arranged to support ingots, forgings, billets, or the like during their passage through a furnace. Two or more of the rails as herein described are to be used.
One of the objects of this invention is to provide a support for material to be conveyed through a furnace which will present a limited contacting surface and thereby reduce friction.
Another object of the invention is to provide a water-cooled rail which will obviate the difficulty due to cold spots on the metal conveyed, caused by water-cooled rails in common use.
Another object of the invention is to provide a heat-resisting rail in which the conveying bar will be held against warping or other distortion in shape so as always to present a level surface to the material to be conveyed.
Another object of the invention is to provide a heat-resisting rail in which the conveying bar may be easily and quickly removed for replacement.
Another object of the invention is to provide a heat-resisting rail that may be readily inserted or replaced in any furnace of ordinary construction.
In the embodiment of my invention herein shown by the accompanying drawings, Figure l is a fragmental side elevation of my improved heat-resisting rail. Fig. 2 is a section thereof taken on the line 2-2 of Fig. 1.
Referring to the drawings, 3 and 4 are opposite flanges forming a supporting member. These flanges are preferably made of cast iron, and may be held together when in place by bolts 5. The heads 6 and nuts 7 of the bolts 5 are countersunk in the respective anges and 4. The flanges 3 and 4 f are formed with circular openings at the top for the reception of a bar 8, and similar openings at the bottom for the reception of a pipe 9. The upper openings are so arranged that the center of the bar which they embrace will liefslightlyl below thehupper surface vof the flanges.
The bar 8 is a solid bar of refractory ma- /terial', preferably wrought iron, and'afords the supporting surface for the travel of material through the furnace. It may be inserted` in place by loosening the nuts 7 on the bolts 5. When these are again tightcned, the ybar 8 is firmly held in position and cannot warp or twist under theheat of the furnace. When worn at the top, it may be rotated to present a new contacting surface, or may be vremoved and another bar substituted, by loosening the bolts V5.
The pipe 9 is adapted to be connected with a source of water supply and to be constantly lsupplied with a circulation of cold water. The heatfrom the materials being conveyed passes directly through the bar 8 and the flanges 3 and 4 and is absorbed by the water circulating in the pipe 9.
It will be seen that the pipe 9 extends below the lower surface of the langes 3 and 4, thus adapting it to be partially embedded in the floor of the furnace to hold the supporting flanges in position. It isfpreferably made with a diameter equal to the thickness of a standard brick, thus facilitating the installation or removal of the rail. f
I claim as my invention:
1. A heat-resisting rail comprising an adjustable ksupporting member, a bar of refractory material supported and held against movement by said member, and a vater-cooled pipe embraced by said mem- 2. A heat-resisting rail comprising a bar of refractory material, a water-cooled pipe longitudinally disposed with relation to said bar, and a member formed of heat conducting material and embracing said bar and said pipe.
3. A heat-resisting rail comprising a bar of refractory material, a water-cooled pipe extending longitudinally of said bar,- and a heat-conducting member n in contact with said bar and said pipe.
4. A heat-resisting railY comprising two oppositely disposed flanges, retaining bolts, a round bar embraced by'said flanges and adapted to form a support, and a watercooled'pipe embraced by said anges.
5. In a heat-resisting rail, the combination of a bar of refractory material, a supporting member therefor formed of heatconducting material, and a longitudinally man STATES PATENT- OFFICE` cooled pipe, and an adjustable supporting' member adapted to support and hold in place said bar and Vto embrace said Watercooled pipe.
7. In a heat-resisting rail, the V'combination of a bar of refractory material, a supporting member made in two parts and hav- Copiesof this patent maybe' obtained for ing at the top acirenlar aperture adapted.
to partially embrace said bar and hold it against lateralor Vertical movement, means for adjustably connecting the two parts of l5 `sa1d member, and a pipe in Contact With said member and adapted to contain a'cool- Ying" fluid..y
In testimony whereof, I have hereunto set my hand. Y
