Definitions

  • This invention relates to a-process and apparatus for the electro-depositionof metals on wire and narrow'strip, hereinafter termed wlre.
  • a coiled bundle of wire is well known in commerce and will be hereinafter referred to as a bundle, the wire being wound into a bundle as it leaves the draw plate.
  • an unplated bundle of wire while still coiled and with its convolutions spread apart is .passed through the solution contained in a plating tank from the one" end of said tank to the other and thebundle," while being so passed through the tank, is slowly revolved substantially' about its own axis, the convolutions being gathered in after lating and the plated bundle is collected eyond the other end of the tank.
  • the process therefore starts .with an unplated bundle of Wire and finishes with, a plated bundle of wire, without any uncoiling of the wire.
  • the wire treated is in continuously coiled condition; and, when one bundle has been passed through the tank, one end of a further bundle can be "connected up to the trailing end of the first bundle so as to make the two bundles a continuous coiled length, in order that the process of plating can continue in respect to bundle aften bundle; r
  • the apparatus comprises a horizontally disposed revoluble main shaft adapted to have a bundle of wire hungthereonand along which the opened out convolutions are caused to pass by the revolution; of the shaft.
  • This shaft is arranged over the plating tank, and from it hang the bundles and the separated convolutions, as Well as the bundles outside the tank and the convolutions being treated within the tank-
  • the revolution of the shaft may alone' be depended upon for causing the opened out CgggOllltlODS topass through the plating t O V ⁇ i i ass I only may be used.
  • An electro-deposition unit preferably comprises a tank containing hydrochloric acid or other cleaning liquid, a swill tank containing water, a sulphuric acid tank, a plat- 1 ing tank, a washing tank, and a drying tank, all arranged in succession below the revoluble main shaft, and the opened ,out
  • the apparatus according to the invention also contemplates a certain arrangement of anodes in the platin tank, and utilizes the main shaft as a catode connection.
  • Fig. 1 is a longitudinal section of an electroplating unit embodying the invention.
  • 1*ig. 2 isa plan View of the apparatus shown in Fig. 1.
  • Fig; 3 is a transverse section on the line A' B, Fig. l. 7

  • Fig. 6 is a diagrammatic view showing how the convolutions are agitated or'rocked in addition to bein revolved.
  • the tank a contains hydrochloric acid or othercleaningdiquid, the tank 0 swill water, the tank 0? sulphuricacid, the tank e electroplating solution, and the tan-kf washing liquid, while 9 is a drying tank.
  • a plating tank his a revoluble main shaft arranged above the tanks and having its ends extending .beyond the ends of the outer tanks and having atone end a spool 21 upon whicha bundle of wire to be treated may be-hung and at its other end with a spool j upon which the treated convolutions 0 wire. are collected.
  • This shaft may be revolved'from the pul l'ey 3
  • An unplated bundle of wire ishun'g upon the spool 21 between the end plates 2? and i and one of its ends is manually threaded through the machine with the convolutions spread apart, so that said convolutions successively pass into and out of the respective tanks while hanging from the shaft h, one or two of said convolutions being ultimately started to wind up into a bundle on the ,outgoing spool j, 'lhis movement or passage of the wire through the tanks is elearly indicated by dotted lines in Fig. 2.
  • That part of the shaft 71', which extends above the plating tank is formed with spaced flanges h forming grooves 72. to guide the convolutions and keep them apart, since in this tank they must be kept separate and clear of thean'odes, which are arranged within the tank as hereinafter described.
  • the revolution of the shaft h is depended upon to revolve the wire convolutions about their own axes, and also to feed thewire convolutions through the tanks.
  • the electro plating tank 6 may be provided ,with any convenient form of anodes,
  • buP preferably, and as shown in the drawings, same are in the form of plates extending transversely across the tank from side -to side of the latter, so that each convolution of wire passes between two transverse stretches of anode plates.
  • m (Fig. 3) represents a transverse stretch of anode plates built upv of four separate plates, m m mfland m, having their 0p posite vertical edges seated in grooves 00. in the sides of the tank and in grooves 0 in a central support p fixed within the tank below the shaft h.
  • the lower anode plates, m and m rest upon bearers g at the bottom of thetank, and these plates are separated from the upper plates m and m by nonconductive glass or other insulating sleeves 1'.
  • each of the upper glass tubes 8 is applied to a rod supported at one of its ends by a clip 8 carried by the upper edge of one of the anode plates and by engagement of its other end in the groove in the support 2.
  • a device '1 serves to hammer out any kinks or bends in the wire convolutions as they leave thein-going spool 11 and before they reach the tanks.
  • This device comprises a bell cranked lever 11 a stationary anvil '0 teeth 02* formed on the side plate i of the spool-z, and a lever 11 hanging from. the support Z
  • the teeth 0* will rock one arm of the bell cranked lever '0 and cause the other arm of the said lever to give a swinging blow to the lever 42 against the anvil '0 between which anvil 'v and lever '0 the convolutions are guided,
  • Fig. 6 the shaft 11. is shown as carrying Spindles are supported upon a frame '9 from a supporting bar 10, and as the shaft h revolves it causes the radial arms 7 and 8 to give intermittent blows to the convolutions of wire :0 on both sides of the shaft it, so that the convolutions, in addition to re volving, are agitated or rocked on the shaft as fulcra.
