ELECTROPLATING RACK.

Applcationled August 22, 1927. Serial No. 214,659.

This invention has for its object to provide a rack for use in the chromium plating ot such hollow screw-threaded articles as the drain connections for sinks and the like.

Another object of the invention is to provide a rack into which the articles to be plated may be threaded for support and for electrical connection in'suitable supporting rings arranged in rows one above the other, and in which each rack is provided with anodes extending through the supporting rings and the articles mounted thereon, there being a series of such rows of supporting rings one above the other adapting the rack for use with a deep bath for quantity production.

Another object of the invention is to provide such racks constituting complete units adapted to be moved from place to place with l the articles secured thereto and capable'ot1 having the anodes and anode frames readily replaced. Y

With the above and other objects in view the invention consists in the rack for chromium plating as herein claimed and all r equivalents.

Referring to the accompanying drawings` in which likecharacters of reference indicate the same parts in different views,

Fig. 1 is a front View of an electro-plating rack constructed in accordance with this invention;

Fig. 2 is a side View thereof with parts sectioned;

Fig. 3 is aplan view thereof; and

Fig. 4 is a sectional view of a fragment of a supporting ring.

In these drawings 10 indicates a pair of vertical side rods connected atintervals by horizontal cross rods 11 somewhat in the manner ot" the rungs of a ladder. These cross rods 11 are preferably welded to the side rods and are ma de up of shouldered threaded rings 12 Welded to short rod sections, said rings being regularly spaced apart and occupying a horizontal planeu The side rods and the cross rods together form a cathode trame for supporting the articles to be electro-plated and for establishing electrical connection therewith, such articles, in this instance drain outlets 13 :tor sinks and the like, being threaded in the rings 12 against the shoulders. rlhe upper ends of the side rods 10 may terminate in hooks 14 for a supporting connection and current carrying connection with the usual negative terminal bars, not shown,

of the electro-plating vat, and projecting from these hooks are rods 15 forming'handles by means of which the rack may be lifted and moved from place to place.

Removably secured to the cathode frame and insulated 'therefrom is an anode 'frame comprising vertical rods 16 detachably connected at their upper ends with a metal top rod-18 and at their lower ends with. a bottom rod 19 of insulating material. The rods 16 form removable anode carriers, the anodes 17 in the form of hooks being detachably secured thereto and each extending upwardly through one of the rings 12 and the article 13 mounted thereon. The top rod 18 has its ends bent toward the cathode frame and connected by blocks 20 of insulating material with angle pieces 21 detachably secured to the side rods 10 of the cathode frame, while at the bottom, rods 16 have their ends bent toward the cathode frame and then downwardly and detachably connected to the insulating bottom rod 19, which is removably secured at its ends to the lower ends of the side rods 10.

The detachable connections between theside rods 10 and the angle pieces 21 of the top rod and between the side rods 10 and the bottom rod 12 are preferably in the form of screws threading into said side rods to permit the anode frame to be readily detached from the cathode frame, and the detachable connection between each anode 17 and the anode carrier 16 preferably consists of screws passing through upturned ends of the anodes and threading into the anode carriers. It will be noted that while the anodes 17 attached to the vertical portion of the anode carrier 16 are substantially U-shaped,those in the lower row connected with the horizontal portion are substantially L-shaped.

At its back, the top rod 18 is provided with an arched clip 22 carrying an angular terminal projection 23 for convenient clamping engagement with the positive terminal of the generator' or other source of elect-ric current supply.

With this invention the articles to be plated, such as the drain connectors 13 :for sinks and the like, are threaded in the rings 12 into firm contact with the shoulders of the rings and when so positioned have the anodes centrally positioned within them, so that the rack may be lowered into the bath and the connections made for the plating operation.

The articles being arranged in vertical rows are suitable for use in deep baths and co-operate with each other in producing an efficient circulation of the electrolyte, each article having a lirm mechanical support as well as a firm electrical connect-ion with the cathode frame. When it is necessary to replace anodes, the anode frame may be detached from the cathode frame and replaced with another trally therethrough, but it is to be understood that the invention is not limited to such purpose but is capable of 'use for electro-plating of hollow articlesv generally.

What I claim as new and desire to secure by. Letters Patent is:

1. An electro-plating rack comprising a cathode trame, an anode frame detachably connected therewitl, said cathode frame including horizontal cross rods one above the other and each cross rod containing a row of supporting rings, and said anode frame including vertical anode carriers, each with a vertical row of hook-shaped anodes extending 'through the supporting rings.

2. An electro-plating rack comprising a cathode frame consisting of Vertical side rods connected by horizontal cross rods at intervals 'forininga ladder-like construction, each of the cross rods containing a row of supporting rings; and an anode frame detachably connected with the cathode frame and comprising vertical anode carriers, top and bottom rods connected therewith and having detachable insulating connection with the side rods of the cathode frame, and hook-shaped anodes on the anode carriers projecting through the rings.

3. An electro-plating rack for hollow screw-threaded articles, comprising a cathode :trame consisting of vertical side rods connected at intervals by cross rods containing rows of screw-threaded supporting rings to have the articles threaded therein; and an anode frame consisting of vertical anode carriers, top and bottom rods connecting the ends of the anode carriers and having detachable insulating connection with the side rods of the cathode. frame, and hook-shaped anodes detachably mounted on the anode carriers and passing through the supporting rings.

L An electro-plating rack for hollow screw-threaded articles, comprising a. cathode frame consisting of vertical side rods and horizontal rods connecting the side rods at intervals and each containing a row of shouldered screw-'threaded supporting rings to have the articles threaded therein in Contact with the shoulders, hooks at the upper ends of the side rods for supporting the rack and for making electrical connections therefor,

landhandles on the hooks g and an anode frame consisting of vertical anode carriers, top and bottom rods connecting the ends of the anode carriers, insulating blocks connected to the ends of the top rod, angle pieces on the insulating blocks having detachable connection with lthe side rods of the cathode frame, the bottom rod being ot insulating material and having detchable connection with the side rods of the cathode frame, hook-shaped anodes detachablyvmounted on the anode carriers and projecting through the supporting rirgs, and a terminal connector on the top TO p In testimony whereof, I aiiix my signature.
