SHEETS-SHEET 2 Willi/WMM *wwwa/awo 1mm/mbo@ fm@ f5 tionfand also for feeding' the electrodes through said electrode collars a. Each 'of these molds,yb, includes a horizontal platform, 53, and relatively removable side and top members, 54 and 55, together with transverse clamps, 56, provided with jack screws, 58 and 59, which are perpendicular to said sideand top members respectively when the' latter are in place as in Figs. l, 5 and 6. The mold Z/-is conveniently mounted on car wheels, 60, 6l,` aving axles transverse to the mold and to the electrode, which run on rails, 62, beneath the electrode, leading to the adjacent side of the furnace and supported by a suitably insulated Hoor. c. This floor also supports, in suitable bearings, 63, Fig. 6, a horizpntal shaft, 64, carrying a pinion, .65, between said rails, which is in mesh with a rack, G6, on the bottom of the mold platform 53.` Suitable means for rotating such shaft may consist of worm gear'-,

ing, 67, Fig. 6, connecting it with the shaft 68 of a small electricl motor, af, or its equivalent. 'lhe mold 7) movesj bodily forward with the electrode in the lfeeding operation. It is shown in Fig. l as it appears immediately after having been closed and before moving it to any appreciable extent. After the mold is moved in successive feeding operaions until its vrear wheels 61 reach said fee shaft. 64, as in Fig. 5, the mold is taken apart by removing said clamps 56 and

removable members

54 and 55, as in Fig. 7, and the operation of building the electrode is resumed.

The specific electrode represented as a whole at tas aforesaid is composed of a large number of relatively small units', 69, 70, Figs. 2 and 3, rectangular in cross scction, including a central tubular unit, 70, to

form a passage 52 'for the introduction of oxidizing material. This tubular unit ZO is *preferably and convenientlyvcomposed of clay or the like, so as to be noncombustible relatively short sections, Fig. 4, of fire and at the same time adapted to be kept open by the sloughing oli" which occurs at the innerend of the electrode. The other units, 69, are of suitable elect-rode carbon.

In building up the electrode, the plat-form 53 of the mold b having been exposed and properly located for this operation, the units are built up thereon layer by layer; care being taken to have the sections or lengths of the carbon units 69 break joint longitudinally as at the right in Figs. l, 5. and 7; and a suitable carbon cement, which may be composed of ground carbon and molasses, is spread between the layers as the work progresses. The operation proceeds in this manner until a sutticient length has been built'up to till or rell the mold b. The side and

top pieces

54 and 55 of the mold b are then applied, being first loosely held in place bythe retracted jack screws of the clamps 56, and ultimately brought together and to gage, as in Fig. 6, by tightening the

jack screws

58 and 59 in pro er order so as to render the electrode rectangular' and of the required dimensions. The mold b is now ready to be used in the feeding operation, as above described, and when it has again reached the position represented in Fig. 5 it again retracted and the building operat1on resumed,

invention into effect., the electrode may be Vbuilt up with or without a tubular unit, and

with more or less numerous carbon units; and other like modifications will suggest themselves to those skilled in the art.

The ,combination and arrangement 'rt' parts, including the electrode collar (L, ,represented by Fig. l, and the provision ot the electrode t with a tubular unit, as represented by F 2, 3 and 4, are claimed in said companion specification forming partJ of said allowed application for patent, (Serial No. 570,836) and are hereby disclaimed i as forming no part of the present invention. Having thus described said improvement, I claim as my invention, and desire to patent. under this specification: l. The within described method of building up a stemless electrode, rectangular in cross section, composed of relatively small rectangular units breaking joint longitudinally, which method consists in building a given length upon an endwise movable support layer upon layer, interposing a` suitable cement between the units, compressing the electrode. to gage by lateral and vcrtical'pressure, freeing and retracting the support. repeating the building up and compressing operation, and so on. The within described method of buildmg up and feeding in a stemless electrode, rectangular in cross section, composed of relatively small rectangular units breaking jointlongitudinally, which method consists of building a' given length 'in site upon an endwise movable support layer 'upon layer, mterposing a suitable cement between the units, compressing the electrode to gage bv lateral and' vertical pressure,` feeding rthe same in end'wise, freeing and reti-acting the 1,043,455; i p a support, repeating the building up and compressing operation, again feeding in; and so on, alternately.

3. The Within described method of building up and feeding in a stemless elect-rode7 rectangular in cross section, composed of relatively small rectangular units breaking joint longitudinally, Which method consists of building a given length in aim upon an endwise movablesupport layer upon layer, interpo-sing a suitable cement between the units, compressing the electrode to gage by lateral and vertical pressure, feeding .the same in en'divise under such pressure, free-- ingand retracting the support, repeating the building up and compressing operation, again feeding in; and so on, alternately.

Apparatus for use in building up an electrode composed of relatively small units breakingwjoint longitudinally and cemented and compressed into a practically liomogeneous mass; Asuch apparatus comprising an endWi-se' movable mold having an electrode support, relatively removable side and f 'top membrs, and transverse clamps provided with compressing means Wliicli interact` with said side and top members.

5. 'pparatus .for ulse in building up an Y electrode composed of relatively small units breaking `joint longitudinally aiildfceniented and compressed into a practically lioinogcneous mass; such apparatus comprising an endwise movable mold having an electrode support, relatively removable side and top members, and `transverse clamps provided with jack screws perpendicular to said side and top member respectively.

6. Apparatus for use in alternately building up in .situ and feeding in under pressure an electrode composed 'il' relatively small units breaking joint longitudinally and cemented and compressed into a practically homogeneous mass; sucli apparatus comprising an endwise movable mold having an electrode support provided on its bottom ivitli car Wheels, asubjacent track fitted to said Wheels and mechanism for propelling the mold back and fortli on said track.

7. Apparatus for use in alternately build- .ing up in situ and feeding in uiider'pi'essure an electrode composed of relatively small units breaking` joint longitudinally and `eemented and Acompressed into a practically homogeneous mass; such apparatus comprising an endwise movable 'mold having` an electrode support provided on its bottom with car Wheels and a ixedly attached longitudinal rack, a subjacent track fitted to said Wheels, and propelling` mechanism in-. cluding a pinion iii n'iesli ivitli said rack,a motor. and Worm gearing transmitting,` inotioii from saidniotor to said pinion; sub-v stantially as liereinbefore specified.
