ART OF MAKING METAL TUBING.
SPECIFICATION forming part of Letters Patent No. 441,375, dated November 25, 1890.
Application filed June 6,1889. Renewed May 14, 1890. Serial No. 351,736- (No model.) I
To all whom it may concern:
Be it known that we, EDWIN NORTON, of Maywood, Cook county, Illinois, and EDMUND ADCOCK, of Chicago, Illinois, citizens of the United States, have invented a new and useful Improvement in the Art of Manufacturing Metal Tubing, of which the following is a specification.
Our invention relates to the manufacture of pipes or tubes of iron or steel or other metal 01' alloy. lleretofore such metal tubes have either been cast in a tubular mold or else formed by welding, brazing, or otherwise uniting the side edges of a strip formed to the desired shape. The cast pipe so produced is liable to be defective from imperfections in the casting, may be easily broken, and can only be produced in comparatively short lengths, and cannot be economically made of small diameter. The welded or brazed pipe produced by the old method can also only be made of comparatively short lengths, cannot be made economically of large sizes, and is frequently liable to part at the weld or joint.
The object of our invention is to provide a method or process by which seamless metal tubing may be made of astrong, homogeneous, and perfect character throughout, and whereby it may be rapidly and cheaply produced of any size or length desired.
To this end our invention consists in pouring or passing a tubular stream of molten metal in contact with continuously-moving chilling-surfaces, which surround the tubular stream on all sides and set and shape the tubular molten stream and convert it into a metal tube as it passes the continuously-moving chilling-surfaces.
It further consists insimultaneously compressing the tubular stream of molten metal against an internal support while it is in the molten or setting state to give the tube produced a strong, dense, and homogeneous structure and free it from blow-holes or imperfections which might otherwise arise from air or gas confined in the molten metal.
To enable our new process to be more readily understood and practiced, we have in the accompanying drawings, which form a part of this specification, illustrated one form through the exit-pipe C.
of apparatus which may be used in practicing our invention, the same being, as we believe, the best form now known to us for the purpose.
In the drawings, Figurel is a side elevation of the apparatus; Fig. 2, apartial central Vertical longitudinal section. Fig. 3 is a hori' zontal section on line 3 3 of Fig. 2. Fig. 4 is a detail View of the shearing wheels or cutters. Fig. 5 is a partial vertical section on line 5 5 of Fig. 2. Fig. 6 shows a modified form of the annular orifice of the pouring nozzle or vessel.
In the drawings, A represents the frame of the machine, which may be of any suitable form to give the requisite strength and afford bearing for the different parts of the machine.
15 B are a pair of revolving wheels or rolls having half-grooves b b in their peripheries conforming to the exterior shape of the tube desired to be produced. As shown in the drawings, the annular grooves Z) are semicircular in cross-section, as the machine is designed to produce a pipeor tube in the form of a hollow cylinder. The grooves b may, however, be made of any desired form, according to the form of the tube desired to be made. The rolls B are made hollow, and have hollow shafts B, through which water or other cooling-fluid is admitted into the rolls 13 from the supply-pipe C and discharged The water entering at the center of the rolls flows out through the branch pipes c, which connect with the interior of the rolls near their periphery, so that the water will circulate to. the periphery of the rolls.
D is a pouring vessel or bowl mounted directly above and between the rolls B B and having a discharge-orifice (Z, through which the stream of molten metal a; flows directly down between and in contact with the walls of the groove b in the periphery of the rolls B. The stream of molten metal flows in a direction tangential to both rolls.
F is a core or mandrel conforming in crosssection to the bore of the tube designed to be produced. The purpose of the core or mandrel is to give the stream of molten metal as it issues from the vessel 1) a tubular or hol- 10w shape. The lower end of this core or compressed metal, and a tube may be made andr lw fimm p eferably,fpmiectld ot tint h w y y mpi ra ear and of xv. ybnfi $1 klfi fili i fif H M-70118.13 any-length or size. desired. 'that'is to'say, to the line joining the axes of The vessel D is furnished with guides or 5 the rolls. The core or mandrel F, in eonnecwings at corresponding to the curvature of tion with the pouring-vessel D, thus serves to the rolls B B and extending down to near give the pouringwessel an annular orifiee d, themeeting line of the ro11s, ,as indicated in so-that the streamwf-mjlte1i njetalissuing liigfxiand. whie'h 'fitwsaidl rolls snugly and 75 these-frome'nrteoeatubumrsha e; f serveto direct the molten meta-1 in the chan- To protect the core F from injury by th nel formed by the annular" grooves b b, and
