tree is for use hiomlsm electroplating.
The ohjeots of the invention are to so. anode which will not readily he broken or: :ureel, the ports 0?. which will he fMi'VQlSJ; effected by the constituents of the eleetrolvtie oath, the improved structure heme; trig; eflective in preventing zleleterious electroly lion in localized areas; the improves enocle oe ins eelepted to suste-ui an even and v, or in service, and being capable of GQOEQQIIQQZQ&1= lecture and use and convenient aoplicetlon for use. Furthermore, the improves. suede is efiective in use in that it provides e greet Ellie. he?) throws or zllsoherge lines for the invention is pertlculerly improveme" in eioosles oherecter shown J. Potent No. 2,199,975.
The annexed drawing and. the iollotvhlg do scriptlon set forth in detail certain meeus em hodyiug the invention, such moons constituting, however, but one of the various forms in which the principle of the invention may he embodied.
In said annexed drawing:
Figure l is e vertical section of e or less conventional assembly of e, treating elemtrolytlo bath contained; therein, and suiteble elec trlcel connections, for electroplating, in which the instant invention serves as the anode;
Figure 2 is 2, broken enlarged side View of improved anode, the bus-bar from which the anode depends being shoe-71o in section;
Figure 3 is e rear View of the elements shows in Figure 2;
Figure 4.- ls 2, .lregmeutery enlergecl section, showing" the upper pest oi is oele, this View particularly illustrating moons for connectins: the anode body to e hooi: means of which the anode ls clependlugly supported from v s. hos-loss;
Figures 5 o transverse rections respectively, in the planes iuciicetetlv lilies e-e and Figure l.
Referring pertlculerly to the annexed drawing in which the some parts are indicated the some respective numbers in the several views, the improved anode l, preferably cost mes? e of the herring-bone type allies used in prac ls suspended in a suite? e serves as the plating sol 2, mixture of ehromic and sul- Moi for chromium pleating, the both 3 sfintdlilfil'l in a, suitable treatment teal "'3 lined with sheet lead. A proper level for the use fCom= e ooitoosetllm oi s molest-eel the gouge mei'lss A. a to Le gal suspended in the h 3 la} hoot: depending from a bushe": 6 mounted upon 9, conductor l, whereby the work l is connected in circuit with the negative pole cl e source oi electric current. The anodes l ere dependinely supported by hus bsss 83 sultehly mounted upon the treatment tank 5?. and which in tum support a conductor 5) whereby the anodes l eotuoeoteel with the positive pole of the curreut'source.
The unmoved ehoele l includes heme-bone body ll having as plurality of oppositely-disposed leterelly -ezzteuderl fine Q2. The body it ere substantially flet pleue members .lclleceot sides are suhstontlslly relatively moguls? so that there are provided eight e ges 18 on each i2 and two sharp l on the hotly member 65 between all jsoezlt arms 82, thus to provide the anode with a comparatively greet number oi electric throws or discharge lines, whereby the anode has great capacity. Also, such construction 'permits the use of a comparatively light anode compared to its capacit and also provides even and uuiform wear as the anode is consumed.
The upper-emu of the euode body l l is enlarged, as indicated. by the end portion 55, end is formed with e sleep socket to. Howevez", the socket E i rloes not extend completely to the bottom of the enlarged end. portion l5 so the an enlarged strengthened section ll of the hocly M is formed between the eottom oi the socket lo and the egelust occurring in this portion oi the anode by reason of its svelght.
The anode l is depeudiugly supported from the hue-her 8 by upper euocle oortlou l8 consist log of e her having on angular lower portion 89 hools-lllse upper end portion so, The ex= trerue lower eml portion of the her if; is secured in the socket Hi5 of the enlefrgecl upper anode body portion l5. Prefemhly,'the eulerseti err-ode portlon l5 is cost around the lower portion of the her ill, and a secure connection between these memhers is obtained by first roughing up the outer surface of the lower portion of the You l8, es my providing notches Figures l and 6, in Whlch key-like messes 35 of the emer er T are iQ f1L e ring the The body ll e which the preponclerent portion is supporting bars 53 i'o per which, for protection against acids and sold 2 aspects radicals, particularly oi the depositing solution, is preferably with a coating of tin and lead.
Lead and copper occasion an electrolytic action which weakens the supporting bar i8, particularly at the joint between this bar l8 and the sup ported anode body I i. pockets at this joint and, in any event, seepage creates small pockets, and in these pockets the deleterious action proceeds which weakens the supporting bar I8. The solution maintaining this deleterious action obtains access to these pockets, largely by reason of solution drip coca sioned by the manipulation of the various elements during the electroplating procedure.
To obviate the creation of these pockets, and the penetration thereof by the solution, and,
- hence, the deleterious electrolytic action men tioned, the angular portion l9 of the supporting rod I8 is provided with a collar 2 l, preferably cast integrally with the supporting rod i8. This collar 2i overhangs the upper end portion of the enlarged anode portion i5 and is so located as to contact with its lower face said upper end portion, when the ex reme lower portion of the rod iB-is properly seated in the socltet i8w After the casting of the enlarged anode portion 15 about the lower end oi the supporting rod 18, the upper peripheral edge portion 22 oi." the enlarged anode portion i5 is peened against the lower face oi the collar 2! to the extent necessary to take up any recess between the collar 2i and the anode portion l5 created during the casting operation, and the joint is then filled or: covered with lead. Thus, the collar 2! acts as a watershed for the drip of the depositing solution and diverts the same back into the bath without its being permitted to seep into or otherwh ter." joint between the enlarged anode port and the support ing rod i8.
What I claim is: V
1. An anode for electroplating comprising a supporting member and loo rancher depend- Oftentlmes there are small therefrom, said members being comprised rounding said Joint and overhanging the body member at the joint, said collar having a clown wardly sloped upper surface whose drip edge extended throughout its periphery exteriorly of and free from contact with the port-ions oi said members forming said joint, and said collar inwardly of its drip edge having sealing engagement in an unbroken and endless band with said supporting and body members.
2. An anode for electroplating comprising supporting member having a depending end tion formed with an imperforate outwardly ex tended collar having a downwardly sloped upper surface, and a body member formed with an up-- per end socket within which said depending end portion is seated with the lower face of the col lar is sealing engagement in an unbroken endless band with the upper end face oi the ice-lug,- member to form a Joint between said mole-b i interiorly of the drip edge of the upper oi the collar, the supporting and body members being comprised oi! diflerent alloys such as, in combination with the plating bath, to maintain deleterious electrolytic action at the Joint tending to weaken the supporting member, said collar surrounding the Joint and overhanging the body member at the Joint, and said drip edge being extended entirely exteriorly 01' said upper end face of the body member, whereby plating bath drip from above the joint is prevented fromcontactlng the latter.
