Fig. 14 is a detail view illustrating the operation of the carrier chains on the grids.

The battery grids, indicated at 15, may be formed especially for use in this machine by being provided with projecting bosses 16 which may be later trimmed from the completed plates.

The invention comprises a stationary frame work 17 which supports a pair of upper vertical track members 18 and a pair of lower vertical 70 track members 18. Two endless vertical carrier chains 19 are arranged to travel on the forward faces of the track members 18. The carrier chains are provided with link plates 19' which engage the side edges of the grids 15 as shown in Figs. 7 and 14. Certain of the link plates 19 are notched as shown at 20 to receive and hold the bosses 16 of the grids and pass the grids downwardly along thetrack members 18 and 18'. The grids are held against the upper and

lower track members

18 and 18 by means of

suitable track bars

53 and 53', respectively.

A pair of angularly positioned magazine feed bars 21 terminate against the plates 19 on the descending sides of the chains 19. The feed bars support an inclined pile of the grids 15, by means of their lugs 16, against the side plates of the chains 19, so that, as the notches 20 in the chains come opposite the lugs 16 of the lowermost grid, the grid will enter between the side plates 19' and be carried downwardly between the track members 18 and the track bars 53. The grids may beY fed to the feed bars 21 in any desired manner such asl by means of aY suitable conveyor 22.

The carrier chains 19 do not extend along the lower track members 18'. They do, however, exert a uniform downward pressure on the entire series of grids to force them downwardly through the lower track members 18'. 'Ihe vertical series 100 of grids in the lower track members is supported by a pair of friction shoes 23, one of which is hingedly pivoted to the lower extremity of each of the track bars 53'. The shoes 23 are constantly forced against the descending grids by 105 means of suitable springs 23' so as to maintain each grid snugly against its neighbor, to prevent paste in the later operations from passing between the grids.

As the grids are released by the friction shoes 'A10 and drop from the bottom of the track members, their lugs will engage a pair of curved guide clips 24 which will force them forwardly out of the' line of the upper grids and deposit them in suitable receiving trays 25. The receiving trays are constructed with a U-shaped cross section without ends or top. The sides are preferably, but not necessarily, provided with a series of plate receiving notches 26 which support the finished grids in spaced relation by means of the lugs 16. The receiving trays 25 are constantly moved forward by means of a pusher chain 27 so as to receive the grids in spaced apart relation.

Thus far, I have described the operation of feeding the grids to the machine, conveying them therethrough, and carrying them away. During their passage through the machine, the grids are pasted or filled with the active material. The paste is received from the mixing vats in two paste reservoirs 28, one being positioned oppo site each face of the grids. Within each of the reservoirs is a vertical shaft 29 carrying a scraper 30 and a discharge impeller 31. A discharge slot 32 is formed in the bottom of each reservoir. Below each discharge slot is a paste hopper 33, in each of which a bladed pasting rotor 34 rotates snugly against the face of the descending grids. Immediately back of the pasting rotor is a bladed impeller 35 which acts to press the paste toward the rotors 34. The rotors 34 and the impellers 35 are carried on rotor shafts 36. The rotor shaft 36 in the front paste hopper 33 is provided with a universal joint 37 which allows forward and back and `angular movement of this paste hopper to conform to any irregularities or variations in thickness of the grids. The latter paste hopper is constantly forced against the descending series of grids by means of suitable compression springs 38. The springs 38 surround, and are held in place by, spring pins 38 which project outwardly from the front of the front paste hopper and slide through bushings in a front plate 75 of a hopper frame 75.

The front paste hopper is provided with suitable side flanges 78 by means of which it is slidably supported on the hopper frame 75 so that it may move forward or back to accommodate variations in the grids. It is desired to call particular attention to the fact that, in this machine the paste is forced into the plates from both sides so the grid will be completely filled regardless of any overlapping or staggered arrangement of the grid bars.

The bottoms of both paste hoppers are arcuate to conform to the outline of the rotors 34. It has been found advantageous to have these bottoms of relatively thin material as shown so that they will act as Scrapers to scrape away any excess paste from the grids as they descend. The tops of the paste hoppers 33 are, of course, open to receive the discharging paste from the reservoirs 28. The grids after leaving the paste hoppers 33 will be completely filled with paste and their surface will be fairly smooth. In order to insure, however, that the paste has been evenly distributed and rmly packed and to remove any excess paste, two rotating series of scraper blades 39 are positioned below thefhoppers so as. to engage the opposite face of the descending series of grids. These scraper blades are carried on suitable spider arms 40 from rotating scraper shafts 41. Both series rotate so that the scrapers will Wipe against the descending grids in an upward direction.

The blades 39 are formed of spring steel or similar resilient material and are constructed so that they can be forced radially inward toward the shafts 41, thus allowing them to remain in contact with the grids for a considerable length of their travel. This inward movement is accommodated by mounting the scraper blades 39 on fiat T-shaped blade arms 42 which are provided with suitable slots 43, which allow them to slide along their attachment bolts 44. The Scrapers are constantly urged outwardly by means of tension springs 45.

Any paste which may adhere to the scraper blades 39 is removed by means of horizontal, hinged, wiping bars 46, which are positioned in the path of the scraper blades on their downwardly moving sides. The wiping bars 46 are hinged upon lateral rods 47 from the framework 17. The wiping bars at the opposite ends of the machine are connected together by means of a suitable connecting rod 48 and levers 49. Thus, as a scraper at one side of the machine strikes its wiper bar 46, it will force the latter downwardly with it while the paste is being scraped away. This downward movement of the wiper bar will act through the connecting rod 48 to raise the opposite wiping bar 46 so that it will be in position to engage the next descending blade on its side. This reciprocating action of the wiper bars continues as long as the machine is in operation and serves to maintain a relatively long scraping contact with the blades and to shake any excess paste from the wiping bars. The latter paste may be collected in any desired manner such as upon suitable small conveyor belts positioned as indicated at 50, Fig. 1, which will return it to the mixing vat or to the reservoirs 28.

At the point in their travel where the grids leave the upper track members 18 and enter the lower track members 18', a pair of driven guide discs 73 are inlerposed. The guide discs 73 engage -the edges of the filled grids and guide and force them into the lower track members 18' and 53'. The discs are notched as shown at 73 to allow them to pass over the projecting lugs 16 of the grids.

It is desired to call attention to the fact that the machine is adjustable for various thickness of grids. This adjustment is accomplished by mounting the entire mechanism at the front face of the grids upon a vertical, adjustable frame 51, which is supported from the main framework 17 upon suitable eccentric cams 52. Thus, by rotating the cams 52 the operator can cause the adjustable frame 5l to move toward or away from the main framework. The track bars 53 and 53 are supported from the adjustable frame 51 by means of suitable arms 54 and spacers 76 so that as the adjustable frame is moved away it will draw the track bars 53 and 53 away from the track members 18 and 18' so as to widen the space therebetween to accommodate a thicker grid,

This movement is also communicated to the feed bars 21 and the reservoir 28 on that side of the machine. The springs 38 aulomatically accommodate the pasting hopper 33. on that side to the difference in thickness.

The entire mechanism is driven from any suitable source of power from a main drive shaft 55, through a clutch 56 operated from a suitable clutch lever 57. The rear scraper shaft 41 receives its power direct from the drive shaft through a. suitable chain 58. The front scraper shaft receives its power through a second scraper chain 59, there being a set of gears interposed so as to reverse the direction of the latter shaft 41. The pasting mechanism receives its power from a vertical countershaft 61, which drives the vertical reservoir shafts 29 through suitable chains 62. The vertical shaft also drives a. horizontal countershaft 63 through the medium of a worm gear 64. The horizontal countershaft drives the rotor shafts 36 through the medium of suitable chains 65. One of the rotor shafts 36 is caused to travel in the opposite direction from its opposing shaft 36 by means of suitable reversing gears66. The pusher chain 27 is driven through the medium of a suitable drive chain 67, there being a suilable speed reducing sprocket 79 interposed to reduce the speed of the pusher chain.

The carrier chain 19, on one side, is driven from the horizontal countershaft 63 by means of a drive chain 70. 'I'he carrier chain at the other side is driven from the first carrier chain by means of an upperfcross chain 71, there being a pair of direction reversing gears 72 interposed to reverse the direction of the two carrier chains so that their inner reaches will move downward simultaneously. The guide discs 73 are driven from the lower sprockets of the carrier chains 19 by means of short chains 74. y

It has been found advantageous to place a spring actuated clutch, such as indicated at 77, 1n the drive to the scraper blades so that should a plate become bent or stuck in the track bars, the drive can be shut off and the Scrapers rotated forward by hand to facilitate access to and removal of the damaged plate.

The above method of driving is simply suggestive of a manner in which the drive may be accomplished. It is, of course, to be understood the various drives for the various parts may be accomplished in any desired manner.

The receiving trays 25 may be fed to and removed from the machine in any desired manner. It is suggested that they be supplied to the machine from a gravity roller conveyor, such as indicated at 68, and removed from the machine on a similar conveyor 69. If it is 'desired to pickle the plates, the trays 25 should be formed of hard rubber or similar acid resisting material so that the completed grids or plates can be immediately placed in' the pickling vats while still in the trays.

The machine has been described as applied to grids of a single plate width. It can, of course, be built to handle grids cast to form two or more plates at a time, by simply widening the machine to accommodate the wider grids.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
