To all whom/jt may concern. f
Beit known that I, CHARLES W. DAKE, a citizen ofthe -United States,residingat Chi# cago', in thecounty of Cook and State of -illinois, have'invented .a certain new and useful improvement in' Arc-Light Eleclwhich the following isa specification. y -My invention -relates to electrodes for arc lamps and particularly' to. ssuchas are introdes, 'ofthe `fusing' point'of such electrodes. 'A particular'case is that Where copper electrodes are employed-in vconnection wither in opposition to othlerfjelectrodessuchfas those of carbon. 'In thi'sf'and many other casesit is l desirabletd'have sinelectrode of'such' a'na-A application ofthejelectrode to. thatparticu lar form of holder whichchere illustrated,v
:ture that it Twill ftendfto radiate heat orl so act as to keep 'fits own Vterr`1pera'tu-re down.
Such an electrode is the object of my invention. 'llt is-illustratcd the; accompanying drawings, wherein-,-
Figurel is a ver-tical section showingvtwo electrodes in opposition to eachother; Fig.
2 is aplan View of the; loWer .electrode and associated parts; Fig. 3 is a cross section en the lineB-roFigf1; land Fig- 4 is-a sideelevation ofthe-electrode. j
Like parts .are ind cated"b'yr the same letter 11i-all the'gures. l
The electrode consists `.if/aicentral with a series of laterally projecting longi-A Htuuiinal ribs B, B threorl.' The total effect 'is that of acorrugatedworfribbed electrode.- 'lhe edges of the ribs arepiteferablynotchedat @,-but this is -only for convenience inthe but male the subject matterof another ap# plication,
Serial A.Number 7 35,033, filed 'Dely cember 5,1912. forV an electrode holder for;
another purpose Vand for that"purpose they arc lamps. These notches, however', have' "are'made as indicated, uniform inv length, ,f
andare associated with. a notched holder as' 45.4
show11. l The' electrode, although!l metallic,
tends, of course, ltofgradufally disintegrate' or lto'become, reduced in length at the point'A Where the .arc is established. Since these notches'are of'uniformv length,- the'y enable 'the adjustment of the electrode to accommo- .dat'e for such Wear' by. uniform increments.
It 'is easy to 'determine by actual experience about how long it takes the electrode to Wear the length ofone notch,jwhe'repon the pracfj tice can be established of moving'the electrode forwardly one notch at the end of Ieach-such periodof time..V The'grooves in the electrode, or the inter-vals between the' ribs serve a further. purpose in that ,they fflirnishlafbearing fora removable 'locking portion of the holder. By thisfmeansA the electrode with its j'projecting parts' ycan be4 held by opposed progectin'g ribs or portions and theholding part prevents its rotation on its ow'n axis.4
I claim:
An electrodecomprising ing ribs'lengitudinal'ly arranged said ribs thereof uniform equidistant notches trans# versely arranged across theouter surface o'f said ribSl v- In testimony whereof, I affix my'signature im the presence-of two Witnesses this 8rd vday cf December,.1912. QHARLES W. DAKE.
