The elevator is operativelyv positioned with respect to the'beams forming the supporting means for anodes to provide means for introducing the anodes into operative relationship with the washing means. To this end short midportion sections ofthe supporting beamsare separate from the main vportions of these beams and areassociated withv verticalemembers adapted to be lowered and raised by suitable elevator-operating means.

in normal operation, with anodes placed upon ivthe supporting means, the apparatus operates as follows: The walking beam yis set `in'motion to advance anodes along the supporting means to its operation is suspended while the walking'beaxn again passes through its cycle. This alternate 'operation of walkingbeamsl i and f elevators oontinues until each anode'placed upon the supporting means has had itsturn upon the elevator and has been introduced into operative relationship with the washing means.

Afrom the'following description, considered in conjunction with the accompanying drawings, in Whicht l k l l isfanelevation of an anode washing machine constructed in `accordance with the invention;

Fig. 5 is 'an elevation showing the mounting of the rotating brushes.

The anode washing machine shown in' Figs.

1 to 4 comprises substantially parallel anode sup4 porting beams I0 and II forming arack adapted to support a plurality of anodes bythe supporting ears or lugs thereof and supportedV themselves by'frame members I2 and `I3 mounted upon'suitf able posts or pillars I4'.l The spacing of the beams" I0 and Il issuch that an anode I5'(Fig. 3) may easily-be receivedbe'tween them and `be supported on them bythe ears or lugs I6 with which anodes are generally provided for hangingthem in electroiytic eens, with the ears of the anode'prpjectf A ing outwardly beyond the outer surfaces Aof the beams. Notches I'I are'providedA in thev upper surfaces of vthe beams I0 and II.l .The width of the notches Il issuch that each lnotch will easily receive an earv of an anode. The notches serve to insure proper spacing of anodes supported 'by tliebeams I0 and II. 'h d y Walking' beams 20 and 2| are eccentrically mounted adjacent the supporting'beams I0 and other.

I I so as to be movable in a substantially circular path of travel with respect to the supporting beams. The mounting of the walking beams is as follows: Bearings 22 are rigidly secured to the outer surfaces of the Walking beams and a cam 23 is housed within each bearing. The cams are secured eccentrlcally to rotatable shafts 24 which are suitably journaled in bearings 25 supported by a frame member 26. The shafts 24 and the bearings 25 in which they are journaled .thus support the walking beams through the cams 23 and the bearings 22 secured to the walking beams.

The shafts 24 advantageously form a part of reduction gears 21, each comprising a worm gear 28 mounted upon the shaft 24 and engaging with a worm 29. The worm 29 of each reduction gear is mounted on one of two line shafts 30 and 3| flanking the walking beams 20 and 2I respectively.` A drive shaft 32 is connected tc each of the line shafts -30 and `3| through reduction gears 33 and 34. A motor 35` provides means for driving thedrive shaft v32 through a belt 36` engaging a pulley 31 mounted on the drive shaft.

' When the motor 35 is running, it drives each of the line shafts 30 and 3| through the drive shaft 32, and through the line shafts and the worms 29 mounted thereon a. turning moment is'applied to the shafts 24 supportingthe Walking beams'. The cams 23 arethereby rotated in their bearings 22, and owing to the eccentric mounting of the cams, the walking beams 20 and 2Imove in such a manner that any point 4on the beamsl travels in acircle of diameter equal to the throw of the cam, each rotation of the shaft 24 and the cam 23 secured thereto actuating the walking beams through a completeV cycle. The position of the walking beams with respect to the supporting. beams I0 andr II is such that when a line drawn through the center of any shaft 24 and the true center of the cam23 mounted thereon is horizontal, the top surface of the walking beam is even with the bottom surfaces ofthe notches I'I in the supporting beams I0 and II.v Hence during half of each cycle of the walking beams, the top surfaces thereof rise above the `^bottom`of the notches I1 and the beams move forward (say from left toY right in Fig. 1) and during the other'half of the cycle the top surfaces of the walking beams fall below the bottom of the notches and the beams move backward- (i. e. from'right to left in Fig. 1). lThe center to center distance between'successive notches Il is sub stantially equal to the throwof the eccentrics actuating the walking beams; hence it will be seen that with each cycle, the walking beams come up under the projecting ears I6 of Ianodes slung between the supporting beams I0 and II, lift the entire burden of anodes, carry it forward ajdistance of one notch, lower it again to the supporting beams, and then retreat into position to repeat the cycle. VIf vno other yaction intervened, the anodes would simply be advanced, one notch with each cycle of the walking beams, from one end of the supporting beams to the It will be` noted. however, that short sections 4I! Y, and 4I of the supporting beams I0 and II `adjacent the mid-portions thereof are separate from the main portions of the supporting beams. Each of these short sections 40 and 4I is of a width to include one of the notches I'I formed in the supporting beams I0 and II, and, when in the position shown in Fig. 1 (except for the fact that they are separated from the mainL portions of simply portions"` of thef' supporting `beams* over which andes maybe advanced `by the" walking` beams zo `and 2|-,

f It will be apparent from the foregoing description.L that means must be provided to correlate the functioning of the walking beams and-elevator if operation'of the machineis to be wholly automatic. Toy this end a drum controller 13 is geared Ato the walking. beam drive shaft 32 so that it passes through one complete cycle with eachv cycleof the walking gbealns.V A seconddrum controller'xllis similarlyv geared to the elevator driveashaftil to passthrough a complete cycle with each cycle of the elevator. y The apparatus may be operated as follows: The walking beam motor 35 is energized, starting the .cycle of. thefwalking beams 20 and 2|.V The drum controller A'13, geared to the walking beam drive shaft 32,`vis so arranged that with the completion of the walking beam cycle, power is cut oi from-the Amotor 35 and a magnetic brake is set to hold the walking beams from moving. As this cycleis completed, the drum controller 13 acts/to energize the elevator motor 52, which starts the elevator in operation. When the motor 252 is energized, the pinions 41 are operated through the drive` shaft 5I and reduction gears 48 and 50, driving theracks 46 mounted on each of the vertical members 42 and 43, the upper ends of which form the short sections 40 and 4I of the supporting beams IU andl Ii. tion ofnthe pinions 4ll on the racks 4,6 causes the elevator to jdescend, and to. rise when the motor 52 is reversedby action' Vof the drumk controller 1.4, which takes place whenthe elevator reaches substantially the bottom of its travel. It is advantageous to include -a timing relay in the control circuit to determine the length of time the ele.

vatorstays at-or near the bottom of its travel lbefore starting to move. up, as this allows for adjustment V'by thefoperator of the amount by which the elevator drifts, assuring complete Ascrubbing of the anodes, and it also prevents .brake releasedl as long as the motor 52 is energized. I'he magnetically operatedY valve 68 preferablyA is connected tothe `brake so that thevalve v|58 remains openswhile ythe brake is off but closes whenthe brake sets. Thisprevents Waste of the fluid while the walking beamv mechanism is motion. ,When the elevator stops .at the upper limit of its travel, thus completing its cycle, the drum controller 14 so acts as to energize the walking beam motor 35, thus startingthe complete cycle over again.

.l A separate motor is used to drive the washing brushes 53. vThe brushes are rotated continuously throughout the performance and for that reason no particular control apparatus is necesv sary for their separate motor'.

It is understood that various modifications may be made in the construction of the machine The acv described above and in its operation. For example, by suitably altering the control circuit, the elevator can be made to pass through two or more complete cycles between each cycle of the walking beams. This may be advantageous when a particularly adherent slime is'to be removed from anodes. Furthermore, the elevator may be designed to carry two or more anodes at a time, and the walking beam may in such case be so designedas to advance the anodes two notches along the walking beam witheachcycle.

In the foregoing description, particular reference has been made to electrical operation and control of the machine. In generalthis is preferred, but if desired, mechanical operation and control may be employed.' Thus, for example,

the elevator may be operated hydraulically instead of electrically.

The machine described above is particularly well suited to cleaning anodes, but it may be adapted to other uses aswell. For example, it may be employed in paintingl or pickling metal sheets or plates by eliminating the brushes and krolls on the platens of a hydraulic press and the machine may be used to straighten metal sheets or plates. Other .modifications of the machine to adapt it. to other uses will also be apparent to those skilled in the art.

As pointed outv above, use of the machine described above for washing anodes, makes possible lifting a plurality of anodes simultaneously from an electrolytic cell, automatically passing them successively in operative relation with washing means. and lreturning the anodes en masse to the cell without substantially altering their spatial arrangement with respect to one another. It will be .apparent from the foregoing description how the, anodes may beautomatically passed successively in operative relationship with washingmachines. v

Inlemploying the apparatus ofthe invention, a plurality of anodes ypreferably are lifted simultaneously from an electrolytic cell Without disturbing lto any substantial extent their spatial relationship with respect to one another, and are then' automatically passed in operative relationship with washing means, for example by Vdepositingthem upon the supporting members of the ariodejwashingI machine described above (the n'otches on the supporting members being such that thespatial relationship of the anodeswith respect to oneanother which on'the machine is substantially the same as-'in the electrolytic cell); Thereafter the anodes are returned cleaned to the cell, still without substantially altering their spatial relationship, and are replaced en masse in the cell. The slime washed from the anodes may, if it is f value, be collected and subjected to suitable treatment.

In accordance with the invention it is possible to wash anodes more economically and much more hspeedily than has heretoforebeen possible. Electrolytic refining processes involving the rapid formation of an adherent lslime on the .anodes maybe dealt with 'expediently by means ofthe invention, -and at a cost that'may well fall below the'costs entailed heretofore, even whenwashing at relatively infrequent intervals, in washing operations involvingv a'substantial amount of hand whereby anodes thereon are moved downwardly has `been moved into contact ,v vithrthel washing into contact with the washing meansbelow the supporting beams, and to return the shortbeam sections to 1 their positions'of alignment with the anode supportingibeamsfthe elevator operating means andthe meansf'ffor moving'anodes only after an anode supported on 'theelevator 4meansand the-short beam sections havebeen returned to their positions "of alignment with 'the supporting beams. f
