ELECTROPLATING' BARREL, AND GATO-HER.

being the provision Aof an finiproyedplating.

barrel whereby lthe operation of plating is reduced to a. minimumand the time required is also Vreduced to a minimum.

Another object is .the provision .of a catcher whereby the plated articles may -be thoroughly v,drained and quickly removed from the barrel in bulk.

Vith these and othervobjects in yview my invention 4consists in certain novel features of construction arrangement and .combina-` tion of parts as Will be hereinafterdescribed and ,pointed out inthe claims, reference being vhad to the `accompanying drawings-ferming ta part hereof, in which, n y

Figure 1 is an end .elevation showing vthe apparatus ready for operation.

Figure 2 is a longitudinal sectionshowing. the catcher in place.'

Figure A3 is a vertical section of the .tank and bar-rel showinguposition of 4Vthe' yarticles before being picked up by the barrel.

Figure 4 is a .vertical -section of the barrel after. revolution through 180 showing 4picking-.up process .co mpleted. y

Figure 5` is a loncftudifnail section ofgthe barrel with catcher remouvec'l and closure in place.

Referring more specifically t0 the drawings 10 indicates the tub or tank in which the plating solution 11 is placed.

Within the tank is supported the barrel which comprises the heads 12 suitably con nected. 13 are bars forming cathodes. 14 is a shaft which also acts as connector for the cathodes Wires 15,v and upon this shaft is mounted the driving pulley 16.

Interchangeable bars 17 are used to hold the covering material 18 of the barrel, which cover material may be either canvas or cloth.

The anodes 19 are hung on metal bars 20 at opposite sides of the tank, said bars being held Within the spaced apart projections 21 at each end of the tank. Negative contact is secured by means of the heavy lever 22 hav ing the brush 23 `thereon Whichis brought into contact Withthe' 4shaftf14, Whichf'as stated connects the cathodes 13 ythrough the Wires15.

The .catcher Which is an important featureof the invention consists .of the ends 24' y, 5 connectedby v the lower side `bars 25 andthe sheet metaltop .26 yWhich is inclined from the topofone side downwardly tothe opposite side Where it .meets the side2 which is `of reticulated material such `as Woven Wire, this side beingcontinued to formthe bottom `28 ofthe catcher; the bottom 28. continues up to aboutv one .half the heightof the opposite side 29,l leaving' an entrance or .throat `BOto the catcher. 'y

tothe opposite Iheads .cr-ends .of thef. barrel.} i

One head of the barrel is provided with .an opening 34y through ivhichthe catclier'gis troduced and when the catcher is notinvplace,

this opening is c losedyby acover .door,y.35p, which is provid'edW-ith the pivoted resilient latch bar 36.... the ends ,of which' will be tricel l tionally .heldfby therfbails v37 asfshown in Figure 1 The operation 'the yappar.atus` isy f0.1*i l The barrel 'is placed in l the tank -Z is.v

filled With'a plating solution and the articles to be plated are first prepared as usual and .then placedin the barrel through the end opening 34; this opening is closedfby the cover door 35 before the current is' turned on. The barrel is now rotated atL a slow rate until the plating is completed. The

cover door35 is now removed and the catcher is introduced into the barrel sliding on the guides 32, With the free end of the top 26 of the catcher fitting closely to the inside. of the barrel so that none of the articles can slip by when the barrel is. again rotated.

The catcher now beingin vplace the barrel is rotated in the direction of the arrow and the articles indicated generally by A will be scooped up deposited Wit., the catcher and carried up by the inclined top 26 andy to the position indicated in Figure 3; in this position the catcher is held stationary a sufficient length of time to allow the surplus solution to drain oil' through the reticulated bottom 2S.

One revolution of the barrel is sufficient to pick up all the articles and after the draining operation is completed the catcher is withdrawn from vthe barrel and the plated articles removed therefrom.

TheA above set forth process can then be repeated.

What I claim is: s Y

An electro-plating apparatus comprising in combination, a solution tank, anodes disposed within said tank at the side thereof, a rotatable barrel comprising end heads and a textileA covering between said heads, said heads rigidly secured to a drive shattmounted in 'said tank, cathode bars held within said barrel and in circuit with said shaft, movable brush means mounted on said tank and adapted to be contacted withsaid shaft, and a reticulated work catcher removably mounted within said barrel.

- 2. An electro-plating apparatus comprising a solution tank, a plating barrelrotatably mounted in said tank, means for supplying current tothe interior ofthe barrel, an anodeextending into said tank adjacent the barrel, and a work catcher removably mountedin said barrel.

3. In an electro-plating apparatus ofthe character described, a barrel comprising a pair of heads and a flexible covering, and a removable work catcher mounted in said barrel.

4:. In' an electro-plating apparatus of the character described, a plating barrel comprising a pair of heads and a cover of textile material between said heads, one head provided with an eccentrically disposed opening or doorway therethrough, and a reticulated work catcher removably mounted in said doorway and within the barrel.

5. In an electro-plating apparatus of the character described and including a rotatable plating` barrel of textile material, a work catcher removably mounted within said bar:A rel, said catcher comprising a reticulated open sided trough adapted to extend from end to end oi' the barrel.

6. An electro-plating apparatus `V,of the character described and comprising a rotatalble work holding barrel provided at one end with an eccentrically located aperture or opening, and means inserted through said aperture and sustained within said barrel. adapted to pick up the plated articles placed within the barrel and carry them up for collection when the drum is given one complete revolution in 'one direction.

7. An electro-plating apparatus or the character described comprising a rotatable work holding barrel provided at one end with an eccentrically positioned aperture, guide ways extending between the ends from said aperture, means tor closing said aperture, and an open sided trough removably mounted on said guide ways, said trough adapted to catch and lift the plated articles within the barrel to position Jfor removal ot the trough with the articles by a single complete revolution of the barrel in one direction.

8. An Ielectro-plating` apparatus as recited in claim 7, the trough comprising a reticulated bottom and sides, and an obliquely disposed top.

9. An electro-plated apparatus as recited in claim 8, the trough including bottom support .bars and to be movably seated on guideways ywithin the barrel.

l0. An electro-plating apparatus as recited in claim 7, the trough being supplied with a top of imperrorate metal, said top extending obliquely from the upper end of one side of the trough and dening a longitudinal throat or opening in the opposite side whereby the said top will act as a scoop to catch and deposit they plated articles in the trough, when the barrel is rotated in one predetermined direction.v
