To all whom it may concern:

Be it known that I, VVILLIs R. KING, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electroplating Plants; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had -to the accompanying drawings, and to charactors of reference marked thereon, which form a part of this specification.

This invention has reference to a novel plant for electroplating hoop-iron, wire, strip-metal, chain, wire-screen, and the like, by means of one contiuous step in the process of .electro-plating.

The present invention therefore has for its principal object to provide a novel arentraordinary long lengths, when it is de- "sired to electroplate the same, most of the old methods requiring the treating of such material in sections, whereby each separate section hasto be handled several times in carrying out the separate steps of an electroplating process. x

Itis one of the main objects of the present invention, to provide a plant, in which such material may be passed through the various steps of an electroplating process, contmuously, without the necessity of the frequent handling of the same; and, consequently the great'expenditure of labor and time incident to such separate handling is obviated.

- One of the main purposes of the present inventionis :to provide a plant for electroplating great lengths of metallic material,

great difficulty to indicate corresponding parts.

whereby the said metallic material may becontinuously fed from reels, drums, or the like, and passed continuously from apparatus'to apparatus, by means of which each separate step of the electroplating process is performed, as said metallic material passes therethrough, and finally winding'or taking up said metallic material in its finished state upon reels, drums or the like;

The plant is-arranged in such a manner, so that each step of the electro-plating process is completed in its proper order, and means are provided for carrying the metallic material from apparatus to apparatus,

whereby the several steps are performed in sequence, until the material is finally completed and in its finished state is finally'deposited upon the receiving reels, drums, or the like.

The invention is clearly illustrated in the accompanying drawings, in which is represented the most complete arrangement of the apparatus and devices comprising the novel plant for the electroplating of extraordinary long lengths of metallic material, such as hoop-iron, wire, strip-metal, chain, wire screen, and the like. a In the said drawings, Figure 1 illustrates a side elevation of the novel plant embodying the principles of the present invention.

Figs. 2, 2 2 and 2, represent in top or plan view, portions of said novel plant, said views being made on an enlarged scale. ,In like manner, Figs. 3, 3 9 and 3, represent central vertical longitudinal sections of'the .parts represented in said Figs. 2*, 2", and2.

Similar characters of reference are employed in all of the above descrlbed views, Referring now to the said drawings, the reference-character 1 indicates any desirable form of supporting frame-work or foundation upon which'the various ,apparatusmay p be arranged.

The reference-character 2 indicates the 1 standards between whichare mounted the shafts 3,-rbea-rin the reels or drums 4 upon which the long engths of metallic'material 5 are carried. The said lengths. of metallic material 5 are first carried 'into a cleaning 1 5 apparatus, which comprises a metallic-tank 6 provided with abindlng-post 7 to which is attached a wire 8 of anelectrical circuit. Arranged within said tank 6 is a. framework -9 which is provided with bearings10, i"

which are suitably mounted rollers 11;

The said frame-work is supported upon the bottom of the tank 6 by means of insulating blocks 12. The said tank 6 is filled with a solution of potash which is kept hot by means of a steam-coil 13, or the like, arranged beneath said tank. This potash solution cleanses the metallic material as it is passed therethrough, from all grease and foreign material which may cling to the surface'of the same. drawn from the reels or drums 4 and passed under the rollers 11 so as to submerge the 'same in the potash. solution, and upon emerging from said solution of potash, the

strips of metallic material pass over a' concompleted through thetank 6, the potash solution to the. strips 5 in contact with the contact rod- 14,' and through the brush 17 and binding-post 16 to said conductor 18. Arranged adjacent to said tank 6 is a tank 19 and rotatably arranged in,

the interior thereof is a guide-roller 20. The tank 19 is filled with cold water and the metallic material is carried from said contact-rod 14, beneath said guide-roller 20, so

as to submerge the same 1n the said water,

- whereby the potash-solution clin 'ng thereto is rinsed orwashed 011', as wil be clearl evident. Mounted between'a pair of stand ards 21 1s a shaft 22'upon which is secured a drivingor conveyin roller 23, over which the metallic" materia 5 is. carried after emerglng from the water in said tank '19.

' Arranged adjacent to said tank 19 is a tank also provided with an internally arranged guide-roller 25, said tank 24- being filled with a pickling solution for the purpose of removing any scale or the 'like, which, in cases where' the metallic material to be plated has been annealed,"may cling to the surface of said metallic material. The metallic material is carried from said-driving or conveying roller 23. beneath the said ic ing solution. 3 Mounted etwe'en a 'pair of standards 26 guide-roller 25fflso-asto submerge the same 1n the said is a shaft 27 upon which is secured adrivingor conveying roller 28, overwhich-the'metal lic" material 5"is carried after emergin from i the said pickling solution. Arrange adjacent to saidtank 24 is a tank 29 which is pro-. vided with an "internally V roller 30, said tank 29 be ng filled with cold wate'r,.a'nd the metallieimaterial 5 is carried from said driving or conveying roller 28 be- .neath said guide-roller 30, so as to be Tut.

The metallic material is arranged .guidemerged in the water, and whereby the pic kling solution clinging thereto is rinsed or Washed ofi" of the same. Mounted between a pair of standards 31 is a contact-rod 32, and arranged upon one of said standards 31 is a binding-post 33, to which is secured one end of an electrical conductor 34 of an electrical circuit. Connected "with said binding-post is a brushholder 35 in which is arranged a suitable brush 36, the free end of which is adapted to be maintained in electrical'cont-act with said contact-rod 32. The strips of metallic material 5 upon emerging from said cold water tank 29 pass over said contact-rod 32 and are thus brought in electrical contact therewith, Arranged adjacent to said tank 29 is another tank 37 which is provided with an internally arranged guide-roller 38. This tank 37 is filled with a solution of copper or other salts so as to provide a copper or other suitable bath, and the metallic material 5 is carried from said' contact-rod 32 beneath said guide-roller 38, so as tosubmerge the same in the said bath. Secured upon the upper edges of the sides of saidtank 37 are contact -rods 39 which'are provided with binding-posts 40, a connecting conductor 41 being arranged between said binding-posts 40. One of said conductors is connected with an electrical conductor 42 of an electrical circuit. Suspended from said 'contact rods 39, by means of suitable hangers, as 43, are

a plurality of anodes 44, so arranged that one group is placed adjacent to the upper surfaces of said strips of metallic-material 5,

and the other group are arranged adjacent to the under surfaces of said strips of metallic material 5. Mounted between a pair of standards 45 is a shaft 46 upon which is secured a driving or conveying roller 47, over which the said strips of metallic material 5 are carried after emerging from the said copper-bath; and, adjacent to said tank 37 is another tank 48 which is provided with tank 48 -is filled with'cold water and the strips of metallic material 5 are carried from said driving or conveying roller 47 beneath said guidemoller 49 so as to be submerged in the said water, whereby any portion of the solution still clinging thereto may be rinsed or washed off. Mounted between a pair of standards 50 vis a shaft 51 upon which 1s secure'da driving or conveying roller 52,

the said guide rollers54 and on a slightlyan internallyarranged guide-roller 49. This lower plane than said guide-rollers 54, are

' ing bracket 58, in the free end of which is arranged a binding-post 59, to which is secured one end of an electrical conductor 60 of an electrical circuit. Connected with said binding-post 59 is a brush-holder 61 in which is arranged a brush 62, the free end of which is adapted to be maintained in electrical contact with said contact-rod-57.

Secured upon one end of said plating-tank 53 are a pair of standards 63 in each of which are arranged a pair of sliding journal-boxes 64. J ournaled in said boxes 64' are shafts 67, and suitably mounted or se-- cured upon said shafts are resilient rollers- 66. Secured to the outer ends of said shafts 67 are gears 65 which are in mesh with each other and are adapted to drive the said rollers in opposite directions. One of said 'shafts 67 is provided upon "one end with a driving wheel 68 of large diameter, said driving-wheel 68 being connected by means of a belt 69, or the like, with a small pulley 70 on a main power shaft 71. The said strips of metallic material 5 are carried from said driving or conveying roller 52, beneath one of said guide-rollers 54, and then extend longitudinally through said plating-tank 53,

being supported by said supporting or carrying rollers 55 and submerged in said electroplating solution, said metallic material then extending beneath the other of said guiderollers 54, at the opposite end of said tank 53, emerging from the said eleetro-plating fluid or solution and then passing over said contact-rod 57, being in electrical contacttherewith, and thence through or between the said resilient rollers 66. Secured upon the upper edge-surfaces of the sides of said plating-tank are contact-rods 72, pro-- vided with binding-posts. 73, a connecting conductor 74 being securedto and joining in electrical circuit. both of said contact-rods 72, one of said binding-posts being connected with an electrical conductor 75 of an electricalcircuit. Suspended from said contact-rods 72, by means of hangers 76, area plurality of anodes 77, which are arranged so as to be grouped between the said guiderollers 54 and each of the said supporting or carrying rollers 55. The'said anodes 77 are further arranged in such a manner so that some of the same extend laterallyacross said plating-tank 53, adjacent to the upper surfaces of said strips of metallic material 5, and other anodes extending laterally across I said tank, adjacent to the under surfaces of said strips of metallic material 5. Arranged adjacent to said plating tank 53 is a naeta-llic tank 78, which is provided with frame-members 79 between which are mounted an internal guide-roller 80 and an outer guide-roller 81. This tank 78 is adapted to be filled with hot water, which is kept hot by means of a steam-coil 82, or any other desirable heating unit, said coil being arranged beneath the bottom of said tank 78. The strips of metallic material pass from said resilient rollers 66, beneath the said internally arranged guide-roller 80, so as to submerge the said strips of metallic material therein, for the purpose of thoroughly cleansing and washing oli of the same any of the electro-plating solution still clinging thereto, the said strips 5. then being carried over said outer guide-roller 81, and thence through the hood 83 of a drying apparatus, said drying apparatus being arranged adjacent to the end of said metallic tank 78. This drying apparatus comprises a box-like compartment 84, supported upon a framework or legs steam-coil 86, or any other desirable heating unit. Connected with thecompartment 84 and arranged above said steam-coil 86 is a perforated plate 87, over which is arranged the said hood with openings 88 at each end for the en trance and exit of said strips 5, the said hood 83 forming a drying chamber 89. v

Mounted between a pair of standards 90, which are located adjacent to the drying apparatus, is a shaft 91 upon which are secured suitable receiving reels or drums 92, upon which the said strips of metallic material 5 are rolled or wound after passing through said. drying apparatus. Secured upon one end of said shaft is a ratchet-wheel 93, and pivotally arranged upon said shaft, adjacent 85, and arranged therein is a 83, the samebeing provided to said. ratchet-wheel 93, is a vibrator-arm or lever 94, the free end of which is provided with a stud to which is pivotally connected a pawl 95 which is adapted to engagewith the teeth of said ratchet-wheel 93. The means for operating said vibrator-rod or lever 94 and thepawl95, toturn or drive the said ratchet-wheel 93", comprises acra'iikshaft 96, one end of which is pivotally con nected with said vibrator-rod or lever 94, and the other end of which is connected eccentrically with the side or plane-surface of a pulley 97 secured to a main power-shaft 98. The reciprocating action of said cranke shaft 96, by means of said vibrator-rod or lever 94 and its pawl 95 thus imparts to said ratchet-wheel 93 and the shaft 91 a rotary motion as will be clearly evident. This motion is slow but very positive and assures the drawing of the said metallic strips 5 through the various devices of the apparatus hererolled in its finished condition upon'said reels or drums 92. To further aid the drawor passage of-said strips of metallic material through the said various devices of the apparatus, the said shafts 22,27, 46 and 51,

upon which are mounted or Secured the said driving or conveying rollers 23, 28, 47 and 52, as well as the various revolving contact rods 14, 32 and 57, are all provided with pulleys 99, and are operativelyconnected with a pulley 100 secured upon one of said shafts 65, so as to pass the driving power from one to the other of said shafts and contact rods 57, 51, 46, 32, 27, 22 and 14:, by means of belt-connections 101, thereby reducing the friction and aiding materially in passing ,the'said metallic-strips 5 through the various devices of the whole apparatus.

From the foregoing description of the novel plant for electro-plating extraordinary long lengths of metallic material, it will be readily seen, that such material is easily -manipulated for the purpose of carrying out the various steps of a perfect electro-plating' process, regardless of the length ofthe material to be plated. The material is passed through the various devices and tanks of the apparatus, such as the potash-tank, the pickling-tank, the copper-bath tank, and their intermediate cleansing tanks, continuously without the necessityof frequent handling; As one portion of material is treated toone step of the process, it passes on to the next device, thereto be further treated, and another portion follows, in sequence, until the plating-tank is reached, where the metal is deposited on said material in carrying out the actual plating step, and then the finished portion is drawn through the resilient rolls 66 which squeeze oif the solution from the finished or plated surface. The further cleansing of said finished or plated surface 1s accomplished in the hot-water tank, and

* thence the material passes to the drying apparatus and is finally reeled upon the receivlng reels or drums 1n its finished'of plated state. The movement of said metallic mavterialthrough the various apparatus, while it is continuous is nevertheless very slow, so

that sufiicient time is allowed to permit of the completion of each preparator step, as well as of the main platlng-step of the electro-plating process, and each portion of said metallic material is evenly and perfectly treated to the final completion of the said process.
