SPECIFICATION forming part of Letters` Patent No. 542,422, dated July 9, 1895.
Application filed April 3, 1895. Serialll'o. 544,279. (No specimens.)
To @ZZ whom it' may concern.- y y, Be it known tha-tl, EDWARD NELSON, of the city of Providence, in thecounty of Providence and ,State of Rhode Island, have invented certain new and useful Improvements in the Method of Making Seamless Plated Wire, of which the following is a full, clear, and exactl description, reference being had to the accompanying drawings, forming part of thisspecification.
This invention has reference to improvements in the manufacture of seamless, solid, or tubular wire, in which the outer surface is made of a seamless tube of precious metal adapted for use in jewelry.
The invention consists in the peculiar and novel method, more fully set forth hereinaft'er, by which a tube is drawn from a disk of stock-plate, covered with a softer metal or composition of metals, and is thcn reversed so that the softer metal is on the inside of the tube and is secured to a solid or tubular core from which the seamless wire is drawn out, as will be more fully set forth hereinafter.
Figure l is a perspective view of a disk of Sheet metal. Fig. 2 is a sectional View of a cup.l Fig. 3 represents in sectional view an elongated cup; Fig. 4, a cup covered on the exterior surface with solder; Fig. 5, the same cup with the solder smoothed down, and Fig. 6 the reversed tube. Fig. 7 is a sectional view of the tube drawn over a core or a mandrel, and Fig. 8 a roller-head by whichthe tube may be spun over so as to' reverse the same.
Similar numbers of reference designate corresponding parts throughout.`
In manufacturing seamless wire by my improved process the disk 10 is cut from a sheet of precious metal, or, as is most usually the case, from a sheet of stock-plate-that is, a sheet of inferior metal plated with a sheet of precious metal. The disk 10 is now placed into a press having a male and female die. The male die forces the disk through the cylindrical hole of the female'die and thus produces the cup shown in Fig. 2, in which the closed end 10n is the central portion'of the disk 10, and the walls 11 are formed from the outer annular portion of the disk 10. When stockhole iu the die.
force the metal of the cup through the per-l die-press and is elongated, as shown in Fig. 3, the walls 11 of which are drawn out. This cup is now thoroughly cleaned on the outside by acid. It is then covered with linx and is placed into a bath of fluid solder, or metal fusible at a much lower temperature than the metal of the cup.
I The solder 12 may beplaced on the outside of the cup, as shown in Fig. 4, in a bath, or in any other manner, pains being-taken that the whole exterior surface is covered with the solder. The solder-covered cup is now drawn through a suitable die to even up the outer layer. of solder, asis shown in Fig. 5. In the cup so prepared the precious lnetal forms the inner surface and the solder the outer surface of the cup. These relative positions I now reverse and this reversal may be done in various ways, to wit: The cup may be placed inverted over a cylindrical perforated die with the closed end 10a resting on the die and a male die used to draw the whole through the A mandrel may be used to foration of the die, or the core to which the shell is to be secured may be forced with the metal of the cup through the die, or the spinning-head shown in Fig. 8 may be used to turn over the tube so as to place the soldercovered surface into the inside of the shell.
'The spinning-head consists in the mandrel press is smaller than the original tube.
The tube, either after it has been turned over or while it is being turned overin the die-press, is drawn over the core, which .has been thoroughlyv cleanedby acidY and covered with-flux or the mandrel 16. If on the core, the tube and core are drawn down together in the vusual manner iuto wire, and when -drawn'on a mandrel* the tube is drawn out 'lengthwise until it has-the desiredl length,
when it may be used'and drawn down to any size of hollow wire required.
By this device the metal form- IOO The disk 10 may be made of any metal or composition of metals desired which, when drawn into the cup form, may be covered on the outside with solder and when turned over may be drawn out into seamless tubular wire.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The method herein described for makingl seamless plated wire, the same consisting in forming adisk or plated sheet-metal into a cup, the plated surface being on the inside, e1ongeting the cup into a tube closed at one end, cleaning the outside of the tube with acid,1
covering the same with flux, covering the outer surface with liquid solder, drawing the solder-covered tube through a die to even the solder, turning the tube so as to bring the solder-covered surface on the inside, drawing the tube over the cleaned and Hux-covered core'end the so-formed ingot into wire, es described.
In Witness whereof I have hereunto set my hand.
EDWARD NELSON. lV-itn esses:
