- the shaft IOI In the unloading position, the shaft IOI is raised to an oblique position above the horizontal level, so that the mouth 96 of the container head 93 is directed downward, and so that the contents of the containers 92 may be discharged therethrough.
- the various positions of the containers 92 are shown in Figure 9.
- Conveying mechanism between cleaning and plating sections of apparatus In order to carry the cleaned Work pieces to the plating section of the machine, conveying apparatus is provided.
- This consists of an end- 0 less conveyor I50, arranged to travel in an orbital path and supported at its opposite ends upon the rotatable drums I5I and I52 respectively ( Figures 6 and '7).
- the drum I5I is mounted upon the frame member I53 and is rotated by the motor I54 through the worm gearing I55.
- the drum I52 rotates loosely aroundthe shaft I51, whereas and arranged to discharge its contents on to the conveyor I50.
- Adjacent to the drumb I52 Adjacent to the drumb I52 is a hopper I62, having a spout I63, projecting downwardly so as to discharge the contents of the hopper into the containers 92.
- the transfer mechanism tilts the container into the unloading position so that it discharges its contents downward through the funnel IN on to the conveyor I 50.
- the latter carries the work pieces upward until these arrive at the drum I52, when they are dumped into the hopper I62 and pass downwardly into the containers 92, the latter being in the loading position as they pass beneath the spout I63.
- the transfer mechanism then carries the containers 92 over the end of the hot alkali tank 3 and into the acid tank 4, where the surfaces of. the work pieces are thoroughly cleaned and pickled by the action of the acid. This acid imparts a roughened surface to the work article which assists in the retention of the plated deposit.
- the containers 92 On arriving at the end of the acid tank 4, the containers 92 are lifted over the partitions and immersed successively into the cold water rinsing tank 5 and the mild alkali tank 6, the latter being intended to neutralize any acid remaining upon the work pieces.
- the containers 92 then pass over the opposite end of the mild alkali tank 6 and are swung upward into the unloading position ( Figures 2 and 9), dumping their contents into the funnel I61, and thence on to the conveyor I50.
- the work pieces move upward on the conveyor I50 and are discharged into the hopper I62 and through the spout I 63 into the containers 92 of the plating section of the apparatus ( Figures 3 and 10. These move over the end wall into the mild acid tam.- 9 by the aid of the transfer mechanisnr Where the surfaces of the work pieces are reactivated immediately prior to their being plated. Any trace of oxide remaining upon the surfaces is thereby removed.
- the tank 9 is preferably lined with rubber.
- the articles in the containers 92 are then immersed in the cold water' rinsing tanks l0 and H, whereupon they pass into the plating tank 12. Here they are subjected to the action of the electroplating current and solution, as they pass in an orbital path through this tank.
- the containers 92 are lifted over the various partitions and immersed in the cold water rinsing tanks l3 and (4 ( Figures 4 and 12), and thence pass though the drying chamber l5, where the moisture on the articles is removed.
- the containers 92 are lifted upward into the unloading position ( Figure 3) and discharge the now-plated articles into any suitable carriers such as trucks or tote boxes.

This invention relates to electroplating apparatus and, in particular, to electroplating and electro-cleaning machines which move the article continuously through the various solutions while treating it.
One object of my invention is to provide plating apparatus including a cleaning section, a plating section, and devices for transferring the work from the cleaning section to the plating section.
Another object is to provide electroplating apparatus wherein the articles to be plated are carried through the various solutions within perforated drums, these drums being simultaneously rotated, moved horizontally through the solutions, and transferred vertically over the partitions or barriers between the tanks containing the various solutions.
Another object is to provide electroplating apparatus having a work holder of perforated drumlike form andassociated with devices for causing it to occupy successively a vertical position for loading, a downwardly oblique position for immersing in the solutions, a horizontal position for passing over the partitions between the various solution tanks, and an upwardly oblique position for unloading.
Another object is to provide a container of drum-like form, which is pivotally mounted and associated with means for raising and lowering it so as to transfer it from one tank to another over the partition therebetween.
Another object is to provide electroplating apparatus wherein the machine is provided with a shaft running longitudinally through the machine, and transfer devices operated from this longitudinal shaft, these transfer devices being adapted to transfer the containers from tank to tank over the barriers therebetween.
Another object is to provide a container which -is adapted to receive its contents when placed in a vertical position, and discharge its contents when caused to assume an upwardly oblique position.
Another. object is to provide electroplating apparatus having a cleaning section and a plating section, together with drum-like containers 'movable through the various tanks of each section, and means for partially inverting the containers as they arrive over a moving conveyor, which serves to carry the articles thus cleaned upwardly to a position where they are dropped into other containers passing thereunder and associated with the plating section of the apparatus.

Figure 10 is a transverse vertical section taken along the line Ill-l0 of Figure 8.
Figure 11 is an enlarged view, partly in section, showing details of the containers and the associated mechanism for transferring them from tank to tank over the partitions therebetween.
The apparatus generally described comprises the sections shown in Figures 1, 2, 3, and 4, placed end to end in the order named. The mid-portion of the section between Figures 3 and 4 has been removed because of its excessive length and similarity to the remainder of that section. The apparatus includes a cleaning section for cleaning the articles prior to their being plated (Figs. 1 and 2); a conveying section for carrying the cleaned articles from the cleaning section to the plating section of the apparatus (Figure 2); and a plating section, comprising a series of tanks through which the articles. are moved, while in the drum-like containers, and subjected to the electroplating action.
Frame and tank construction v The cleaning section of the machine (Figures 1 and 2) is provided with a frame, generally designated I, and preferably consisting of structural steel members of channel or similar cross section. This frame is provided with vertical stanchions 2,
- which support it and elevate it from the floor.
The cleaning section of the apparatus further includes the rectangular tanks 3, 5 and 6, on opposite sides of the frame I, and having the U-shaped tank 4 with the ends of its arms adjoining them (Figure 1). The tank 3 is intended to contain a hot alkaline solution, the tank 4 an acid solution, the tank 5 a cold water rinsing bath, and the tank 6 a mild alkaline solution.
The plating section of the apparatus has a similar frame, generally designated 1, which in turn is mounted upon the vertical stanchions 8 which elevate it from the floor in the manner similar to that of the cleaning section (Figures 3 and 4). The plating section is likewise similarly provided with rectangular tanks 9, I0, I I, 13, I4, and I5, disposed on opposite sides of the frame 1. The plating section of the apparatus likewise contains a U-shaped tank i2, the ends of whose arms adjoin the ends of the oppositelydisposed rectangular tanks H and I 3.
The tank 9 is preferably rubber-lined. and contains a mild acid solution, the tanks it and it contain cold water rinsing baths, the tank l2 contains the electro-plating solution, the tanks i3 and I4 contain cold water rinsing baths, and the tank l5 contains drying devices for drying the articles while they are yet in the containers. The tank I4 is identical in construction with the tank l3, and occupies a position between the tank I 3 and the tank i5, but is omitted by reason of lack of space.
The various tanks of the cleaning section are supported and elevated above the floor by the frame members 86, whereas those of the plating section are similarly supported upon the frame members 81. The tanks of the plating section are provided with longitudinally disposed rods 88 (Figures 10 and 11), supported above the tanks and serving for the suspension of anode bars 89 through the hook portions 90 thereon. The anode bars 88 are curved and their lower extremities rest upon the supporting members 9| within the tanks.
Carrier and driving mechanism The carrier and driving mechanism for the cleaning section of the apparatus is similar to that of the plating section. The frame I (Figures 5 and 10) is provided with longitudinal channel members 28, through which passes the driving chain 2|. the sprockets 22 and 23 arranged at opposite ends of its run. The sprocket 23 is an idler sprocket and is mounted upon the bracket 24 having the adjustment screw 25, by which the chain 2| may be tightened.
The sprocket 22 is fixed to the vertical shaft 26, which passes upwardly into the reduction gear case 21, mounted upon the cross bracket 28. The reduction gear case 21 contains reduction gearing whereby the speed given the sprocket 2| is greatly reduced from that of the power source.
On the opposite side of the reduction gear casing 21, the shaft 28 emerges therefrom and is supported by the shaft hanger 28, mounted upon the bed frame 38, which in turn is supported upon the cross bracket 28 and upon other cross brack-- ets II, 32, and 33 respectively. The shaft 28, at its opposite end, passes in the change-speed gear box 34, having the adlusting wheel 85. Beyond the adjusting wheel 35, the shaft 36 continues through various couplings to the driving motor 31. The change-speed gear box 34 and the driving motor 31 are likewise mounted upon the bed plate 38. By turning the adjusting wheel 35, the shaft 28 may be given The latter is supported upon different rates of rotation, as compared with the shaft 36 coming from the motor 31. In this manner the sprocket 22 and the sprocket chain 2| may be adjusted to have any desirable speed.
The shaft 28 is likewise provided with a sprocket 48, which communicates power through the sprocket chain 4| (Figure 5) to the sprocket 42 of the gear box 44. On the opposite side thereof, the shaft 45 carries the sprocket 46, which drives the sprocket chain 41. The latter drives the sprocket 43, secured to the main transfer drive shaft 48 (Figures 5 and 10). The shaft 48 is supported in the pillow blocks 49, mounted upon the stanchions 2.
Arranged parallel to the shaft 48 and placed below it is the shaft 58, which likewise passes longitudinally through the apparatus. The shaft 58 is supported upon the pillow blocks 5|, likewise secured to the stanchions 2 (Figures 5 and 10). The mechanism beyond these shafts and driven by them will be described later in detail.
The plating section of the apparatus is provided with similar channel members 52 (Figures 7 and 11) which serve to guide a sprocket chain 53, supported upon the sprockets 54 and 55 (Figures '1 and 8) at opposite ends of the run thereof. The sprocket 54 is mounted to rotate loosely upon the stub shaft 56 mounted in the bracket 51 (Figure 7), which in turn is adjustable by means of the adjusting screw 58, in order to take up slackness in the sprocket chain 53. The sprocket 55 is mounted upon the vertical shaft 59, which passes into and is driven by similar mechanism to that of the cleaner section, previously described: similar numerals are accordingly employed for this mechanism in both sections, and a single description suffices for both. The main drive shaft 60 of the plating section of the apparatus is thus driven in a similar manner to the main shaft 48 of the cleaning section. In a similar manner the shaft 6| below and parallel to the shaft 68 is supported, as previously described for the shaft 58.
The cleaning section of the machine is additionally provided with a pair of longitudinal shafts 62 and 63, rotatabiy supported on the brackets 64, attached to the stanchions 2 (Figure 9); and the plating section of the machine has similar shafts 65 and 66 rotatably supported upon the brackets. 81 attached to the stanchions 8. The shafts 62 and 63 of the cleaning section are driven by the motor 68 (Figure 6) through the intermediate mechanism comprising the sprocket 69, the sprocket chain 18, the sprocket 1|, the variable speed driving pulleys 12 and 13 joined by their belt 14 between their respective shafts 15 and 16; the sprockets 11, the sprocket chains 18, and the sprockets 19 mounted upon the shafts 62 and 63. Similarly the sprockets 8| on the shafts 65 and 66 of the platingsection of the machine are driven from the motor 88 (Figure 7) through similar mechanism, consisting of similar parts bearing similar reference numerals to those of the driving unit for the cleaning section, just described. The variable speed drive 12 to 14 of the cleaning section is adjusted by means of the hand wheel 82, mounted upon the shaft 83 Figure 6), whereas that of the plating section is adjusted by the hand wheel 84 mounted upon the shaft 85 (Figure 7).
Containers and transfer mechanism for lifting the containers from tank to tank work pieces .into the container during the loading operation.
The sleeves 94 of the containers 92 are mounted upon hollow shafts 91, which carry the worm gears 98, meshing with the worms 99 upon the shafts 65 and 66, previously described. The containers for the cleaning section of the machine are similarly driven from the worms I (Figure 9), mounted upon the shafts 62 and 63, previously described.
The hollow shaft 91 rotates upon the fixed shaft IOI, which is secured in the socket I02 of the bracket I03 (Figure 11). The lower end of the shaft IOI is provided with the lock collar I04. The ball bearings I05 and I06 provide free rotation for the containers 92 upon the shafts IOI. Passage of electricity through the shaft IM to the work articles is insured and assisted by the flexible chain-like member I01.
The bracket I03 is provided with a downwardly extending arm I08, which carries the roller rotors I09, making contact with the rail IIO (Figure 11); and also carries the slider III, which slidingly engages the cathode rail II2. In this way the electricity is conducted from the cathode rail II2 through the bracket I08 and the shaft IM to the work pieces in the container 92 by way of the chain I01.
The arm I I3 of the bracket I03 is provided with the pivotal connection I I 4, by which it is pivotally mounted upon the base I I5. The latter upon its upper portion carries the rollers H5 and III, which engage the outer and inner surfaces respectively of the channel members 52. The lower portion of the base H5 is provided with the stub shaft II8, which carries the collars H9 and I20, which engage the outer and inner flanges respectively of the upper and lower guide rails I2I and I22 (Figures '7 and 11) The upwardly extending arm I23 of the bracket I03 is provided with the roller I24, which is adapted to engage the transfer mechanism, which will now be described.
The transfer mechanism for lifting the containers 92 over the partitions between the various tanks consists of an assembly of parts, one assembly being mounted adjacent to each partition or end wall of the tanks. This transfer assembly consists of a vertical arm I30 which is pivotally mounted upon the shaft 6| (Figure 11), and in this manner is adapted to swing to and fro like an inverted pendulum. The mid-portion of the vertical arm I30 is provided with an elliptical opening I3I, which is engaged by a cam follower I32 mounted upon the crank I33, whose opposite end is secured to the shaft 60. The upper end of each vertical arm I30 is provided with a slotted portion I34, which engages a stud I35, mounted upon the pin I36. The latter is secured in the transverse horizontal shaft I31, which is mounted in the shaft hanger I38 having the bearing portions I39, through which the shaft I31 slidably passes. The outer ends of each shaft I31 are provided with cross bars I40, secured thereto, each end of the cross bars I40 (Figures 3 and 11) being adapted to engage the rollers I24 on the brackets I03 of the containers 92.
Consequently, when the shaft 50 is rotated, the vertical arm I30 oscillates like a pendulum, reciprocating the horizontal shafts I31 and moving the cross bars I40 transversely. The rotation is synchronized so that the cross bars start moving at the exact instant that the containers 92 arrive at the various partitions between the tanks, or at the end walls of the tanks. The reciprocation of the shaft I31 and consequently the height to which the container 92 will be raised around its pivot II4, will be regulated by the amount of reciprocation given to the shaft I31, and this in turn is regulated by the throw of the crank I33.
The container bracket bases II5 are attached to the sprocket chains 2I or 53, depending upon whether they are mounted upon the cleaning section or the plating section of the apparatus. The horizontal orbital motion of the sprocket chains carries the containers horizontally through the tanks, while being simultaneously rotated around their shafts IM and lifted over the partitions between the tanks by the transfer mechanism, just described. The rotating of the containers 92 gives a tumbling action to the work pieces and also insures their being completely plated upon all sides. Contact with the cathode rail H2 is broken when the transfer mechanism lifts the container 92 out of the tanks.
Depending upon the adjustment of the transfer mechanism, the containers 92 are adapted to occupy any one of the four positions, namely, the loading, immersing, transfer and unloading positions. In the loading position, the axis of the shaft IN is vertical and the funnel-shaped mouth 96 of the container head 93 is ready to receive articles dumped therein, as shown in the center of Figure 2. In the immersing position, the container head is still upward, but the shaft IOI is in an oblique position. In the transfer position, while passing over the partitions or ends of the tanks, the shaft IOI is still oblique, but in a more nearly horizontal position. In the unloading position, the shaft IOI is raised to an oblique position above the horizontal level, so that the mouth 96 of the container head 93 is directed downward, and so that the contents of the containers 92 may be discharged therethrough. The various positions of the containers 92 are shown in Figure 9.
Conveying mechanism between cleaning and plating sections of apparatus In order to carry the cleaned Work pieces to the plating section of the machine, conveying apparatus is provided. This. consists of an end- 0 less conveyor I50, arranged to travel in an orbital path and supported at its opposite ends upon the rotatable drums I5I and I52 respectively (Figures 6 and '7). The drum I5I is mounted upon the frame member I53 and is rotated by the motor I54 through the worm gearing I55. The drum I52 rotates loosely aroundthe shaft I51, whereas and arranged to discharge its contents on to the conveyor I50. Adjacent to the drumb I52 is a hopper I62, having a spout I63, projecting downwardly so as to discharge the contents of the hopper into the containers 92.
Thus when the containers 92 holding the cleaned articles arrive above the funnel I6I, the transfer mechanism tilts the container into the unloading position so that it discharges its contents downward through the funnel IN on to the conveyor I 50. The latter carries the work pieces upward until these arrive at the drum I52, when they are dumped into the hopper I62 and pass downwardly into the containers 92, the latter being in the loading position as they pass beneath the spout I63.
Operation rotate and move longitudinally through this bath,
while. all grease is thereby dissolved from the surfaces of the work pieces. The transfer mechanism then carries the containers 92 over the end of the hot alkali tank 3 and into the acid tank 4, where the surfaces of. the work pieces are thoroughly cleaned and pickled by the action of the acid. This acid imparts a roughened surface to the work article which assists in the retention of the plated deposit. On arriving at the end of the acid tank 4, the containers 92 are lifted over the partitions and immersed successively into the cold water rinsing tank 5 and the mild alkali tank 6, the latter being intended to neutralize any acid remaining upon the work pieces. The containers 92 then pass over the opposite end of the mild alkali tank 6 and are swung upward into the unloading position (Figures 2 and 9), dumping their contents into the funnel I61, and thence on to the conveyor I50.
The work pieces move upward on the conveyor I50 and are discharged into the hopper I62 and through the spout I 63 into the containers 92 of the plating section of the apparatus (Figures 3 and 10. These move over the end wall into the mild acid tam.- 9 by the aid of the transfer mechanisnr Where the surfaces of the work pieces are reactivated immediately prior to their being plated. Any trace of oxide remaining upon the surfaces is thereby removed. The tank 9 is preferably lined with rubber. I
Passing over the partition, the articles in the containers 92 are then immersed in the cold water' rinsing tanks l0 and H, whereupon they pass into the plating tank 12. Here they are subjected to the action of the electroplating current and solution, as they pass in an orbital path through this tank. Beyond the plating tank [2, the containers 92 are lifted over the various partitions and immersed in the cold water rinsing tanks l3 and (4 (Figures 4 and 12), and thence pass though the drying chamber l5, where the moisture on the articles is removed. After passing out of the drying chamber, the containers 92 are lifted upward into the unloading position (Figure 3) and discharge the now-plated articles into any suitable carriers such as trucks or tote boxes.
