i said articles may be uickl immersed in and removed i'rom the e ectroyte or bath, and my invention has particular reference to gelvanizing, by electrdeposit of zinc, a lurality of pipes simultaneously', suoli vas i es used as conduits for electric conductors. y n carrying out my invention l provide a Suitable tank for the electrolyte or 'oath with means forsuspending e. plurality oi anodes therein arrangedlin-a plurality of series, one series of anodes being surroun ded by another series of anodes, means for connecting all of said anodes in a circuit, and means-for simultaneously inserting a plurality oi' articles to be electro-plated'into the electrolyte in the space between said plurality of series oi anodes andi'or quickly removing said articles fromI the electrolyte, with means for con f .necting said articles in series in tbe circuit. 30

My invention also comprises the novel de tails of A improvement and combinations of arts that will be more fully hereinafter set orth and then pointed out 1n the cleini's.

Reference is to be had to the accompany-U drawings forming part liereoii, wherein i igure 1 is a vertical section of an electrof pla'ting'apparatus embodying my invention. ig. 2 is a plan view, pertlv broken, of the cathode plate` from which tlie articles to be plated are sus ended, Fig. 3 is a plan view of'.

the tank wit the cathode plate removed, Fig. e is a cross section on the line ft, fl, o1

yimilar numeraleoi reference indie-ete con responding parts in the'. several views.

4The numeral 1'v in the accompanying draw ings'indicateska.suitable tank within which the several series of anodesZ, 3 are suspended. allieve shown tank 1 as provided Cin-its upper edge/with. a metallic rim 4i shown provided 'with a binding post 5 for connection or' th a 4 P, line wire- 6, and the hooks fwhich support the anodes 2 4within the tank rest, and ineke 'electrical contact with said run 1. Within the space bounded-by the 'anodes 2 is a suitable post 8 secured to the bottoni of the tank and. extending near the to thereof, through which. post a conductor 9 eads and is shown extending through tbe bottoni of the tank and connected with post 10 on metal rim 4, and upon the upper end of said post .is a metal oontect 11 in circuit with ,conductor 9. The anodes 3 ere maintained in circuit with conductor Q by ineens of thecontact 11, 'for which purpose l have shown metal hooks 12 in circuit with. contact 11, which hooks su l have shown the hoo s port the anorl'es 3.

12 as formed on a disk 13 that rests upon contact .11, which disk rney have e central opening 15 to permit access to conductor 9 et .its point oiE connection with contact 11. The hooks 12 can be hung seperately upon contact 11 in the manner that the hooks 7 hong upon ritn 11, if desired. I have shown content 11 and disk 13 es concave-convex fitting each other whereby the hooks 12 are inaintaineifl in proper position upon ost 8. The height oi postv 8 within tank 1 is such that the books 12 will be above the level of the lelectrolyte or bath in said tank, and may be substantially at the height oi hooks 7, which. also are to be above the electrolyte. ln the space between the outer series of anodes 2 and tbe inner series of anodes 3 the articles-16` to be electro-pl ated are suspended, so that the electro-deposit may be quickly evenly made upon said articles.

At 17 cathode plate of suitable metal' iroinwhiob. the articles 16 are to be suspended in the electrolyte in the tank, which cathode .plate is oi such diameter as to permit it topasswbetween the outer series of anodes 2 and their books 7. The cathode plate 17 is shown provided with a series of threaded. ap- Y ertures 17a, on its under surface, to which pipes 16 to be plated may be screwed so as to depend from plate 17 into the electrolyte in tank 1 between the several series of anodes 0 q A" l. .l

l have shown pipes 16 as arranged 1n` circles,- one within another, around anodes 3,

with suitable spaces between said pipes so .that the metal to be deposited on t 1e pipesofthe anodes, I have shown the cathode 8 and anodes 3 which are a dapted to roject into said opening or space' abevethe evel of the bottom of cathode plate 17! i At 19 is a suitable eye bolt connected with cathode 'plate 17 Wherebythe latter may be raised and owered. Plate17 isshown provided with a binding] post `20 for connection with ,a\line wire Z1 of the circuit. l." electro-plating by means of my improvements, the anodes will be hung in series, (one series within the other) upon their lrespective hooks 7`and 12, and the pipes or articles 16 to be plated will be`attached to cathode plateI 17 which will then be lowered to im'- merse saidpipes in the electrolyte in tank 1, and the current from line wire 5 will flow g through the anodes and thence through the electrolyte, thearticles 16` and cathode late 17 tothe line 21, and when the articles ave `been plated the cathode plate with the ai;

i tached articles will be removed, and a ne 25 set oflarticles attached to said plate and low-y er'ed into the electrolyte for electro-plating in the same manner. Y

A relativelylarge number of articles 16 may be attached tb cathode plate 17 forlsimultaneous plating' and simultaneous rer moval from' the electrolyte or. bath, and

thereby l am enabledto readily and quickly electrolate a large number of articles and particu arly those ,of v,considerable length, such as iron pipe for electric conduits. Such pipe may be readily galvanized in my apparatus by means oi zinc anodes, and by the arrangement c the exterior series of circularly disposed anodes 2 and the interior series of anodes 3 the exterior Vannular surfaces of the The particular arrangement ofparts may4 l be variedgwithin the scope of the appended f claims without departing from the spirit`oi' between said series of anodes.
