METHOD OF VIORKING METALS.
Application filerl ll'une 24,
1 0 all whom may concern Be it lmo'wn. that we, Onivnn C. GILBERT and Slocan W. Armies, citizens of the United States, residing athlew York, in the county of New York and Flt-ate of New Yorlg'and at East Grange, in thc'county of Essex and State of New Jersey, respectively, have invented certain new and useful improvements in llclethods o'lf Vorking Metals, of which the following is a full, clear, concise, and exact description.
This invention relates to a processitor winking metals and their. alloys. llilore'partioularly, the invention relates to a process of drawing metals whereby the drawn metal is given a shape, which cannot be obtained by the use of rolls and which cannot be feast bly attained with the use of a shaping die.
In the embodiment illustrated, the improved process is shown as applied in the manufacture of tinsel formed of copper or other non-ferrous metals but it is to be understood the invention is not limited to this specific application or to the treatment of metals having the susceptibilities of copper or other nonferrous metals because the process herein may be employed to advantage for other purposes than the fabrication of tinsel and for the workingof all metals whether non-ferrous or not.
F igure 1 of the drawings illustrates dia grammatically a means by which the process may be employed. Fig. 2 is an enlarged per spective view of the die employed in the drawing process and also showing in detail the shape imparted to the drawn metal by the drawing operation.
Fig. 3 shows diagrammatically the steps generally employed in the manufacture of tinsel, the size of the metal being greatly magnified.
Fig. 4 illustrates diagrammatically the steps employed in the manufacture of tinsel where a metal drawn by the process herein illustrated is employed, the size of themetal being greatly magnified.
In carrying out the process, wire 0 formed of copper or other non-ferrous metal, is wound upon a storage roll 1, and steel wire 3 is wound upon a storage roll 2. The capacity of the roll 2 containing the steel wire may be much less than the capacity of the roll 1, the reasons for which will hereinafter appear. The copper and steel wires are Specification of Letters Patent.

drawn together througha die 3 by means oi drums 4 and 5, to which the copper and steel-wires are connected respectively. The drum 4 is driven by a pulley '6 and belt 7 connected to any suitable source of motive power, while the drum 5 is driven by a large gear 8 meshing with a small gear 9 fastened upon the shaft 10 supporting the drum 4 and pulley 6. Due to this driving arrangement, the drum 4 is driven at a much greater speed than the drum 5 andconsequently the length of the copper wire drawn through the die 3 is much greater thanthatot the steel wire. 1 The copper or other non terrous metal wire is much softer; than the steel wire and when both are simultaneously drawn through the die, the steel wire will'not be materially affected by the action of thedie, whereas the copper wire willbe formedinto a substantial crescent shapems is shown in Fig. 2, the entire surface of the copper wire being l1ardened by contact with the sides of the die and the steel wire, 3. v The steel wire 3 has such a relatively slow movement through the die in comparison with the copper wire that it serves as a part of the die 3 to shape the drawn copper wire. The steel wire-is given a continual and gradual movement through the dieto distribute the weanincident to the drawing operation along a considerable lengthcof wire. l
The process just described is well adapted for the manufacture of tinsel. In practice, tinsel is made by drawing copper or other non-ferrous metal wire through a die which slightly reduces its cross section, and at the same time gives the drawn metal tensile strength. The metal thus drawn is flattened to'produce tinsel. Fig. 4 of the drawings illustrates these steps which have heretofore been employed for making tinsel, 11 representing the wire previous to being drawn, 12 the drawn and slightly reduced wire, and 13 the drawn wire flattened into tinsel. It has been found in practice that when tinsel is made in this manner, the flat tening of the drawn metal destroys to a considerable extent the tensile strength imparted to it by the reducing operation, this loss of tensile strength increasing proportionally to the amount of flattening the drawn wire needs in order to form it into tinsel.
The process for drawing copper wire and increasing its tensile strength, which has through the die simultaneously with the copper wire and 16 the drawn wire flattened into tinsel. The wire 15 drawn by the process previously described has a great tensile strength, and having-a crescent shape, needs much less flattening to form it into tinsel.
than where the drawn wire has a circular cross section.
What is claimed is: l 1.'The method of worklng non-ferrous metals consisting in drawing a non-ferrous metal and a metal harder than the non-ferrous metal through adie together.
2. The method of working non-ferrous metals consisting in drawing a non-ferrous metal and a metal harder than the non-ferrous metal through a die together and causing one of the metals to pass through'the die at a greater speed than the other.
3. The method of working non-ferrous metals consisting in drawing a non-ferrous metal and a metal harder than the non-ferrous metal through a die together and cans ing the non-ferrous metal to pass through the die at a greater speed than the other 1 metal.
copper wire to pass through the die at a greater speed than the steel wire.
6. The method of making tinsel consisting in drawing wire to give it a crescent cross section'and then flattening the drawn wire.
7. The method of making tinsel consisting in drawing a non-ferrous metal and a hard metal through a die together to form nonierrous wire having a crescent-shaped cross section.
8. The method of making tinsel consisting in drawing a non-ferrous metal and a hard metal through a die together to form a nonferrous wire having'a crescent-shaped cross section and then flattening the drawn wire.
9. The method of working metals consisting in drawing two metals of different degrees of hardness through a die together and causing one of the metals to pass through the die at a. greater speed than the other.
10. The method of working metals consisting in drawing two metals of different degrees of hardness through a die'together and causing the softer metal to pass through the die at a greater speed than the other metal.
11. The method of making tinsel consisting in drawing two metals of different degrees of hardness through a die together so as to give the softer metal acrescent-shaped cross section.
' 12. The method of making tinsel consisting in drawing two metals of different degrees of hardness through a die together so as to give the softer metal a crescent-shaped cross section and then flattening the drawn metal.
In witness whereof, we hereunto subscribe our names this 19th day of June A. D., 1919.
