EDGAR PEGKHAM, OF SYRACUSE, NEWV YORK.
LINING FORTHE GROOVES OF PlPE=WELDlNG FURNACES.
SPECIFICATION forming part of Letters Patent No. 313,102, dated March 8, 1885.
Application filed March 4, 1884. (No specimens.)
To all whom it may concern.-
Be it known that I, EDGAR PECKI-IABI, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Linings for the Grooves of Pipe-Velding Furnaces, of which the following is a full, clear, and exact description.
This invention relates to the refractory lin ing required in the pipe-carrying groove of a pipe-welding furnace, said groove being arranged inside of the furnace and subjected to intense heat, required to bring to a weldingheat the pipe which is carried in said groove, and when heated as aforesaid is moved longitudinally along the groove and out of the fu rnace direct to the welding apparatus.
Inasmuch as it is essential that the surface of the groove should be capable of resisting the heat it is subjected to, and should be maintained true and smooth, considerable difficulty has been experienced in providing a proper lining for said groove, and various refractory or fire-proof materials have been employed for that purpose. New Jersey fire clay mixed with crushed or ground fire-brick or ground-u p saggersa compound commonly used for repairing linings of furnaces-has also been resorted to to line the aforesaid groove; but such a material is incapable of resisting the heat for a great length of time, but soon becomes vitrifierhor blistered or cracked, and then loses its requisite uniformity of surface, and the particles which scale off from the surface frequently adhere to the heated pipe, and are subsequently embedded in the surface thereof, thereby impairing the finish of the pipe. To obviate these defects, l. em-
ploy chiefly the waste or broken unglazed white ware or O G ware, usually termed biscuit, which ware,itis well known,is composed of some of the purest and best fire-proof materials-win, feldspar, pure kaolin, and chinaclay, and will retain its shapeunder fire. This material I crush or grind into small particles, (not necessarily in the form of powder,) and spread the same over the snrfacetof the groove by a long-handled scoop shaped implement or other suitable or convenient means. When the groove is so defaced or out of repair as to require a thick coat of lining, I admire raw kaolin with the aforesaid ground white ware. The glazed ware is not desirable,0wing to the glazing, which is a flux, and therefore impairs the capacity of the material forresisting heat.
As already stated, I am aware that various refractory entire-proof materials have been employed for the lining of grooves of pipewelding furnaces and for analogous purposes; but I do not know of a single instance where unglazed burned white or G C ware, or its equivalent-win. burned compound of feldspar, kaolin, and china-clay, either with or without raw kaolin, has been used for the afores tid purpose; hence \Vhat I do claim specifically is 1. The improved lining for the groove of a pipe-welding furnace, consisting of biscuit or unglazed burned white or (J G ware, or its equivalentviz., burned compound of feldspar, kaolin, and china-clay reduced to small particles.
2. For the lining of the groove of a pipewelding furnace, a compound of biscuit or an glazed burned white or C C ware, and comminuted raw kaolin, substantially as specified.
In testimony whereofl havchereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State ofl ew York, this 1st day of March, 188
