Specification of Letters Patent.

Application filed September 4, 1909. Serial No. 516,162.

paratus for the production of. wire, especially copper wire.

The object of my invention is to eliminate the rolling mill from that series of operations whereby a metal is reduced from the form of ingots to the form of wire.

While my invention may be applied to the production of wire fromv various metals and alloys, it is; peculiarly well adapted to the manufacture of copper wire, and for this reason in the description of the process which follows I shall refer to thatmetal.

The usual procedure in making copper wire is as follows: 1. The pig copper is cast into anodes. 2. The copper of the anodes is electrolytically deposited upon plates of pure copper, forming cathodes of pure copper, while the impurities of the anodes are retained in the depositing vats. 3. The

cathodes are melted and cast into in ots orbars. 4. The ingots are passed severa times through a rolling mill to form wire rods. 5. The wire rods are drawn through a succession of draw-plates to form wire.

By my process, I deposit the copper of the anodes upon an endless wire which is kept in motion partly or entirely in the solution in an electro-plating vat, and which is constantly being drawn out from one end of the vat, thence through a draw-plate and returned by means of suitable mechanism to the remote end of the vat throu h which it again passes. It is the sense 0 my invention that the wire which leaves the drawplate shall be substantially the same as that with which the process started. Thus if number 14 wire were placed in the vat, it would be drawn through a number 14 drawplate. By this means the cop er which has been deposited on the origina wire during its passage through the electrolytic solution causes the wire which reaches the drawplate to be of somewhat larger size than it was at the point where it entered the solution.- The process of drawing the Wire through the draw-plate constantly restores the wire to its original diameter, whereby the growth of the wire, by the gradual addition of copper from the solution is lengthwise. By means of suitable mechanism the wire is fed into one end of the vat at the same rate that it is taken out from the other end. Therefore the vat is always full of wire and consequently working at its maximum capacity in depositing copper. Since the wire on its assage through the drawplate is elongate it will move more rapidly than that portion which is being returned to the vat, so that wire will constantly accumulate outside the vat in exactly the proportion that copper has been added to it during its passage through the solution. When a suflicient quantity has, in this Way, accumulated outside the vat, the wire on each side of the finished coil is cut. The

- coil is removed and the ends of the shortened sure are oined by welding. The process then goes on as before until another portion of wire has accumulated.

The process may be carried out in the apparatus which is shown .in the .accompanying drawings and which also forms a part or my invention.

In saiddrawings: Figure 1 is ,an elevation, part in longitudinal section, of the apparatus. Fig. 2 is a top plan view of the electrolytic vat., Fig. 3 is a transverse vertical section through the vat near the end. Fig. 4 is a detail view of a portion of the grooved drum for carrying the wire through the vat, and Fig. 5 is a detail view of a portion of an anode, showing one of the hooks by which it is hung.

Referring now more specifically to said drawings 1( indicates a vat of suitable construction for containing the electrolytic bath. The vat 10 is adapted to receive and contain a frame comprising a base 11 and side pieces 12, 13, the base extendin from one end of the Vet to a block or shou der 14 at the other end, and the side pieces having upper projections 15 and lower projections 16 extending to the sides of the vat so that the frame is held in proper position within the vat. This construction permits raising and lowering of the frame when necessary. The side ieces are also rovided with bearings 17 For the groove drum l8 and slot bearings 19 for the drum 20. The grooved drum 18 and the drum 20 are adapted to supportand advance the wire 21 within the electrolytic bath, the drum 20 being suspended by the wire and guided by the slots 19. Grooved drum 18 has a driving gear wheel 22 which meshes with a gear wheel 23 secured on shaft 2e journaled in bearing 25 in the wall of the vat 10, and driven by belt pulley 26. The engagement of the gear wheel 23' is made when the frame is lowcred into the vat by having the gear wheel 23 underneath the gear wheel 22, which con-' struction at the same time permits the raising of the frame from the bath. The block 14: above referred to is of such dimension as to fill in thespace between the. end of the base 11 and the frame and the endof the wall of the vat 10, which space must be left to provide for the clearance between the frame and the gear wheel 23 when the frame is raised. The wire 21 is wound over the two'drums 18 and 20, each turn of wire being disposed in one of the grooves of the drum 18so that upon rotation ofthe drum the wire is fed constantly forward throu h the bath. The wire issues at the end of the bath over an idler 27 through a suitable wash 28 for removing the copper sulfate or other objectionable substances from the bath, and thence over an idler 29 under'a take-up device 30 and over an idler 31 through draw-plate 32, being drawn through the draw-plate by the drawing drum or block 33 of well known construc-. tion. The coil formed on block 33 feeds 01f under an idler 3a over idler 35 and is directed back to the grooved drum 18 by the idler 36. The idlers 27 and 36 may be mounted in suitable manner upon the side 'pieces- 12 and 13 respectivel of the frame and preferably idler 27 w' be ositioned so as to maintain the alinement o the wire as it comes from the drum, whilethe idler 36 is positioned so. as to maintain the alinement of the wire as it comes to the drum, thus maintaining the plane of the wire on each idler normal to the axis of rotation.

The anodes 37 are preferably provided with hooks 38 in known manner, whereby they are hung uponconducting rods 30, 40, joined by conducting bar 41 to which current is led ing frame thus formed may rest upon the to 011 preferably one at each side of .the drums 18 and 20. The current passing into the anodes and from them through the bath into the copper wire may led oil by brushes 43, 44 and conductors 45, 4-6 to common conduetor 47. g

In operation the copper wire is suitably wound upon the drums 18 and 20 an passed through the draw-plate and other parts of the apparatus with several turns deposition. The height by conductor 2. The conduct of the vat and the anodes be hung there-.

' which comprises about the block 33. The frame which supports the drums 18 and 20 is raised during this operation. The frame is then lowered into operating position with the gear 22 in mesh with gear 23, and the ends of the wire welded together. The apparatus is' then set in motion and the wire passes continuously through the electrolytic bath and the draw-plate in cyclic manner. The drawing drum or block 33 serves to pull the wire through the draw-plate while the grooved drum 18 serves to advance the wire through the electrolytic bath. The drum 20,

being suspended by the wire and being capable of slight vertical movement, maintains the proper tension on the turns of wire which pass over the grooved drum 18,

whereas the take-up device 30 keeps the wire under proper tension as it goes to the draw plate. The block 33 being continuously rotated coils the wire in well known manner giving it off at the end of the coil. The diameter of the wire will be slightly increased during its passage through the electrolytic bath and this increment in diameter is changed'to a lengthwise increment by the passage of the resultant product through the draw-plate. The lengthwise incremeht is received and taken up by the block 33 so that as the operation progresses the coil on block 33 will be growing. When the increment reaches the proper amount it is separated from the rest of the wire and the endsv of the remaining wire 'are quickly welded together by electrical or other suitable means well known to those skilled in this art. The ends are preferably butt welded so as to avoid, so far as possible, any unevenness in the joint. During the passage of the wire through the electrolytic bath any unevenness which there might be at the joint will be largely equalized y the of the solution may be such as to entirely cover the turns of wire 11 on the drums. 18 and 20, or when desira le may be ke of the turns wi 1 be out of thesolution'.
