1,091,559. specification of Application led July 28,
To allfwhom it muy concern.'
Be it known that I, JOHN W. Baown, `a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and `State of Ohio, have invented a certain new f a/'built-up electrode, that is, one which is made of several segments or parts that are suitably secured together to form a unitary structure.
A' further object is to construct an eleci trede which may be continually built up otherwise made, if at all, and one Way and added to as the electrode is consumed -.in its use.
Generally speakin the invention oomprises the elements and combinations thereof setforth in the accompanying claims.
Reference should be had-to the accompanying drawings forming a part of this specification in which-- Figure l is a vertical elevation of one form which the electrode` may assume. Fig. 2 is a horizontal cross sect.. n of the showing in AFig. l. Fig. 3 is a partial Vertical secs tion upon the line 3 3 of Fig. 2. Fig. et is a/tpip plan view of amodiiie'd form of electro e.
It is the usual practice at the present time 4to make electrodes such as are used in electric furnaces by'forcing a suitable carbon mix through a suit-able die which vproduces a solid electrode of the desired size.v Such electrodes after being baked, are ready for use. The size or diameter of electrodes which may be thus forced is limited and this limiting size is reached when the friction between the die and mix retards thefmovements of the outer portion of the mix to such an extent that the central part of the mix moves faster than the sides, resulting in the uneven forcing of the mix, which produces checks and cracks in thefinished electrode. y"
,The limit as to di/ax'nl er of electrode which ,may be forced i much below that which 'it is frequently l desired to force. Hence the larger lsite electrodes must bj o accomplishing thel making of large, elec! Letters Patent. Patented lua 1911. Serial No. 641,123. l
be understood that no limitation is herein trodes is herein shown. However, it should intended to be placed upon the .size of elec-, trodes which' may be produced, for the ini vention is'susceptible of being used in the manufacture of electrodes of any size deslred. l
Theelectrode shown in Figs. 1 and 2 is cylindrical and is composed of the segments a, b, c, d, e and f, although the precise number of segments is not essential, that being a matter of choice. lThe segments are securedeach to the other, and as one' means for the purpose, the segments' may be keyedl together, that is, each segment may be providedwith 'a groove and projecting ribs upon opposite sides thereof, the groove being coiiple-mentary to the rib. In assemblingthe0 various segments, the rib upon each segment engages with the groove upon the segment adjacent to it, as will readily be understood from an inspectionof t-he drawengage each other with a wedging action in order that the segments may come .close together,- and therefore the ribs are shown with sides whichfslant so that the part of 'the rib whiohfjofins the body is the narrow- 'est part thereof; The grooves are undercut in a 'manner to complement the ribs: When the sections are thus formed, they are assem-A solid or cored, the irst form being shown in Fig. 4, while the second form shown in Fig. 2. If it is desired to produce .an electrode of apredetermined length, the segments are lpreferably of one piece, and each end of they electrode is finished fiat.v .At the present time,'it is the practice touse electrodes in an electric furnace of a predeter- 'is that part engaged by the electrode holder.
ing. Preferably, the rib and groove should constructed as just described may be either mined length and these electrodes are used fauntil all is yconsumed but the butt end', which 1When the electrode is consumed, the butt end is removed and discarded -as Waste, and a new electrode inserted in its place.
As was lstated in the firstpart of this specification, an electrode constructed in aocordance with this invention may be so made that it maybe continually built up WhileA or set of electrodes which vary in height or r length, Therefore, the iirst set of' electrodes will present the appearance ort spiral steps.
These segments are joined together in the same manner as has heretofore been indicated. To the iirstserles of segments, there is added a second series which are of equal length, these being iitted upon the segments of the first set, from Which it will be apparent that the ends of the second set of segments also present the appearance of spiral steps. The ribs and grooves of the second set of segments engage With the ribs and grooves of the first set throughout p0rtions' of their length and in building up an electrode when a third set of segments yis added, they will engage with the second set and so on ad nmtum. rifhe reason for starting theelectrodes with the segments of varying length is that the joints in the various segments, as they are built up, may
brealr with each other, and thus produce an electrode of unbroken continuity. The ends ithe segments are preferably beveled as indicated at g in Fig. l. "When, therefore, two alined segments engage each other, there is a wedging actionv between them which forces them into close relationship With each other und with adjacent segments.
Fig. iL illustrates an electrode having a ditferent external. iorm than thatI shown in Figs. l and 2, although the construction is otherwise the same. It is therefore intended io place no limitation as to the external shape which the electrode may assume. j It desired, the contacting surfaces of the Various segmen-tsof the electrode may be coated ends of the segments cooperating 'ments being stageered wi therese with some form of cementitious materiai which Will cause the adjacent segments to -adhere to eaeh other. When a hoilow cored form oi the electrode herein shown is used the continuity of the-helios portion may be interrupted in any desired manner either by the .use of solid or grinding material comple' ely or partiaiiy filline ...he hoiloived portir Havingr t17 l claim is:
