Description
~'76~Z
BACKGROUND OF THE INVENTION
In the manufacture of storage batteries, particularly lead-acid type storage batteries, one or more elements are provided within a battery case containing el~ctrolyte. The elements generally comprise a plurality of alternately positive and neg-ative battery plates each separated by a sheet of insulating material commonly referred to as separators. The battery plates each typically comprise a relatively fragile supporting grid having a lead paste applied thereto. Conventional practice has been to form the battery elements so as to have one more negative plate than the number of positive plates so ~hat the end most plates of each element are negative plates. The battery elements will thus contain an odd number of plates whic~l may vary from as low as five plates on up to 25 plates depending on the desired capacity of the storage battery.
Various devices have been provided for assembling battery plates and separators into elements automatically to eliminate stacking by hand. Such devices have generally operated in one of two broad catagories. The Eirst catagory utilizes a top lift system as seen in U.S. Patent No. 2J790~536 issued April 30, 1957, to Reed; and U.S~ Patent No. 2~830,692 issued April 15, 1958 to Winkel. In the top lit arrangement, vacuum type suction devices or mechanical means are usually provided to lift individual bat-tery plates and separators from the tops of feed stacks and ar-range them înto alt~rnating battery elements. While thP top lift system provides or ease in transferring thin, fragile separators and battery plates, movement through relatively large distances l~ .
,. '' ' ~ '.
.
\
-~ A74-7 :~76~C~2 is generally required thereby reducing the speed at which systems can operate.
The second catagory of battery element forming apparatus utilize a bottom shuttle system in which individual plates or separators are stripped from the bottoms of stacks of feed stacks and deposited into battery elements. Examples of the shuttle type devices are seen in U.S. Patents No. 2,897,950 issued August 4, 1959 to Reed; 29624,106 issued January 6, 1953 to Lund; 2,652,933 issued Septem~er 22, 1953 to Willard et al; 2,807,227 issued September 24, 1957 to Kerns et al; and 2,908,377 issued Oc~ober 13, 1959 to Winkel et al. In the shuttle type devices, a pusher plate is generally provided for stripping a battery plate or separator by pushing motion parallel to the plane of the plate or separator.
The disadvantage of this type of arrangement rests in the fact that the plates and separators are relatively fragile and are easily buckled during such pushing motion thereby often causing jams and disrupting the stacking process. A further disadvantage of this type of system is that the weight of the remaining members of the feed stack, from which the lower-most elèment is stripped, bears down upon the moving lower plate resulting in abrasive and frictional forces between the surfaces of the adjacent stationary member and the moving plate or separator. Attempts have been made to reduce such frictional forces, however, the shuttle type systems are generally limited in the speed at which they can be operated.
SUMMARY OF THE INVENTION
The present invention basi~ally comprises an apparatus ~or forming battery eLements of positive and negative battery plates .
~ ~ 7 ~ Z ~ 2 and separator. The apparatus generally in~ludes a loading plat-form having a plurality of feed stations on which separate feed stacks of positive plates, negative plates, and separators are supported on rotatable discs. ~ach rotatable disc has an aper-ture conforming to the configuration of the individual plate or separator and the disc may be rotated to align the aperture with a similar aperture formed in a support platorm for deposit-ing individual plates or separators onto a moving conveyor belt.
Fixed guides are provided at each station for maintaining the individual feed stacks in a rotatably fixed position over the discs while allowing the feed stacks to move downwardly by gravi-tational force into contact with the aperture of the rotatable disc. Upon successive reciprocal rotation of the disc, single plates or separators are directed from the bottom of the feed stacks through the apertures in the discs and the apertures in the platform down onto the conveyor to form books of plates and separators which are combined to form elements. Controls are provided for varying the configuration of the various elements formed after removal from the conveyor belt.
It is an object of the invention to provide an improved apparatus for assembling ba~eery elements.
A further object of the invention is to provide an apparatus for assembling battery plates and separators by stripping a plate or separator from the bottom of a feed stack by rotating the lower-most plate or separator relative to the remaining feed stack mem-bers.
Another object o the invention is to provide an apparatus :~G97~
stripping battery plates or separators from a feed stack with reduced slid-ing contact.
According to the broadest aspect of the prese~t invention, there is provided feed apparatus for dispensing battery plates or separators from a stack supported from the underside of the lower-most member of said stack, said apparatus comprising means for maint~ining a stack of plates or separa-tors in a horizontally fixed position over means for receiving said plates and separators, means for pivoting the lower-most member of said stack be-tween a first position in alignment with the remaining stack members and a second position axially aligned with the remaining s~ac~ memb~rs but rotation-ally displaced therefrom, and means for permitting said lower-most member to be deposited on said receiving means from said second position.
The invention will now be described in greater detail with refer-ence to the accompanying drawings, in which.

As seen in Figure l, the battery element forming apparatus com-prises a loading station lO on which individual feed stacks of positive plates, negative plates, and separators are placed .. , . , ., ., , , , . , . :
-~Ci762(;~;~
for arrangement into elements of alternating plates and separa-tors, a ferris wheel type transfer device 12 for removing books from the loading station 10 and for placing them on an output conveyor unit 14 for removing the elements for further processing.
With reference to Figures 1 through 3, ~he loading station 10 is seen to compris a plurality of individual stack feed stations 16a - 16e supported on a base plate 22 w~ich in turn is supported on a sui~able framework 23. A dual strand conveyor assembly 24 is supported within the framework ~3 benea~h the base pla~e 22 for receiving individual battery plates and separ-~ ~--h ~
, ~t, ators in a~m~ to be described hereinafter. A drive assembly ~, 25 is also supported within the framework 23 for providing motive power to the conveyor assembly 24 and other components of the apparatus as will be described later.
Referring generally to Figures 1, 2, 3 and 5, the construction of the feed stations 16a through 16e will now be described. Since each of the individual feed stations 16a through 16e are identical-ly constructed, only one need be described in detail, and like parts are designated by like numbers with subscripts a ~ e as appropriate. Feed station 16d includes a circular disc 30d having a generally rectangul~ar shaped aperture 31d formed in its central portîon. The disc 30d is supported,on the top of the base plate 22 which has a similarly shaped rectangular aperture 33d fornled therein. With particular reference to Figures 5 and 8, the plate 30d is rotatably affixed to the top surface of b~se plate 22 by a plurality of bearing assemblies 35d spaced around the periphery of disc 3Vd. Each bearing assembly 35d may consist of generally ~ ~ ~ 6 2 ~ Z
L-shaped bracket 37d ha~ing one leg extending in spaced relation-shlp above the edge of the upper surface of plate 30d. One or more rollers 38d may be provided between the brackat extension and the top surface o~ disc 30d for rollably engaging the upper surface of disc 30d. Similar rollers 39d may be provided between the peripheral edge of di~c 30d and a downwardly extending inner portion o bracket 37d. Bracket 37d may be secured ~o the base plate 22 by conventional means such as bolts 40d. Adjusting shims 41d may be provided between the adjoining surfaces of brack-et 37d and base plate 22 for adj usting the bearing load of bear-ings 38d. It will thus be ~een tha~ the disc 30d is vertically and horizontally fixed relative to base plate 22 by the bearing assemblies 35d, but the disc 30d is free to rotate within the con~ines of bearing 35d. Thu~, the disc 30d can be rotated to position aperture 31d into and out of alignment with aperture 33d formed in the base plate 22. The rotation oi disc 30d may be provided by a double acting fluid cylinder 43d which extends generally horizontally along the upper surface of base plate ~2, Cylinder 43d may include an extensible shaft 44d having a clevis 45d which is pivotally connected to a pivot pin 46d extending from the plate 30d. The opposite end of cylinder 43d may have a clevis 48d secured to a pin 49d fixed to base plate 22. Cyl-inder 43d may be of any suita~le fluid actuated type such as air or hydraulic and has a pair of ~luid conducting lines 50d and 51d connected thereto in a conventional manner fur ac~uating cylinder 43. Lines 50d and 51d may be coupled to a suitable sour~e of pres~urized ~luid. (not shown) ~ 6 --- . .... . : ~ .

As shown in Figures 5, 6 and 7, feed station 16d also in-cludes a pair of spaced, vertically extending angle brackets 55d . and 56d which engage diametrically opposed corners of a stack of separators S2. Angle brackets 55d and 56d are each supported by a block 58d attached to base plate 22 outside the confines disc 30. Generally horizontally extending rods 60d may be attached to each of the angle brackets 55d and 56d and the rods 60d may extend throu~h apertures 61d formed,in blocks 58d. An adjusting screw 62d will be provided in the side of each block 58d in com-munication with the aperture 61d for frictionally engaging rod member 60d for adjusting the vertical and horizontal positions of angle brackets 55d and 56d. Brackets 55d and 56d are each adj.usted horizontally to slidingly engage the opposed corners of the horizontal stack of separators S2, and are vertically adjusted to provide a small clearance space between the lower portion of the brackets 55d and 56d and the upper surface of disc 30d.
As seen in Figures,5 and 6, when the aperture 31d o~ disc 30d i. positioned so as to aline the opposite corners of aper-ture 31d with the position of the stack o~ separators S2, the lower-most member of the stack will be guided by brackets 55d .
and 56d into the aperture 31d of disc 30d. Further motion of the stack members will be limited by engagement of the lower-most member with the upper surface of base plate 22. The thickness of disc 30d in the region beneath brackets 55d and 56d will be approxima~ely equal to the thic~ness of the separators S2 so that only one separator will be contained within aperture 31d ~ 7 --.
~7~
of disc 30d. The p2riphery of the disc 30d may have increased thickness if necessary to reduce warping or deflection of the disc during rotation. To further influence the downward motion of the lower-most separator member, a plurality of apertures 65d are provided in base plate 22 at a position in alignment with the corners of the staek of separators S2 such that the aper-tures 65d are exposed within aperture 31d when disc 30d is posi~
tioned to align the aperture 31d with the separators S2. A
manifold 66d is provided along the bottom portion of plate 22 and extends around the exterior of aperture 33d formed in the base plate 22 and has its interior communicating with each of the apertures 65d. A suitable high vacuum line 67d may connect the interior of manifold 66d with a suitable source of vacuum ~hereby creating a suction at each of the apertures 65d tending to draw the lower-most separator S2 downwardly into aperture 31d of disc 30d.
From the foregoing description, it will be appreciated that when cylinder 43d is actuated to position disc 30d with its aper-ture 31d in general alignment with the stack of separators S2, the lower-most separator will be drawn both by gravity and vac- :
uum into the aperture 31d of the disc 30d with further motion o:E the se~rator limited ~y support of its corners on the exposed portions of base plate Z2. Actuation of the cylinder 43d to ro-tate disc 30d so as to position aperture 31d in alignment with aperture 33d will resuLt in the pivotîng of the lower-most separ-ator 5Z contained within aperture 31d into alignmen~ with aper-ture 33d of the base plate 22. The separator will then fall :~716~
through aperture 33d of base plate 2~ under the influence of gravity alone. Rotation of the disc 30d will also result in closure of the vacuum apertures 65d by moving aperture 31d out of position over the apertures 65d. It will also be appreciated that the angle brackets 55d and 56d will restrain the remaining separator stack members S2 from pivotal motion with disc 30 thereby effectively resulting in a stripping of the bottom separator S2 from the stack with ultimate deposit through aper-ture 33d of the base plate 22. Recycling of the cylinder 43d and disc 30d will provide a similar stripping action as to the remaining separators S2. It will also be apparent that the amount of sliding contact between the pivoting lower-most separator and the adjacent separator is signîficantly less than that present in conventional shuttle type systems.
As seen in Flgures 1 through 3, the separate feed stations 16a through 16e are arranged in a line along the top of base plate 22 and each contain a stack of similar battery plates or separators. Station 16a is provided with a stack of negati~e plates designated as Nl, station 16b contains separators desig-nated as Sl, station 16c contains positive plates designated as P, sta~ion 16d contains separators designated as S2, and station 16e contains a stack of negative plates designated as N2. Each of the feed stations is constructed in a manner simi-lar to that of feed atation 16d with the exception that the /~1 Ibc ~Qd /~e A battery plates at stations ~6~ 24-are of generally sufficient mass to enable the elimination of vacuum apertures 65d, manifold 66d and vacuum lin~ ~7d provided for the separators which are gen~

Conveyor assembly 24 is located beneath the base plate 22 within f~amework 23 for gathering books oi plates and sep-arators and is best seen in Figures 3 and 9. Conveyor assem-bly 24 generally comprises a pair of parallel endless chains 75 which are arranged to have a substantially horizontally extend-ing run beneath ~he base plate 22 of the loading station 10.
The opposite ends o~ the parallel chains 75 are supported on a first pair of sprockets 76 located at the end of base plate 22 adjacent station 16a, and a second pair of sprockets 77 located ~t the opposite end of the loading station 10. Sprocket pairs 76 and 77 may be supported on horizontal shafts 78 and 79 respectively which may be journaled in bearings (not shown) in any conventional manner. A third sprocket pair 80 may be simi-larly iournaled on a shaft 81 beneath the upper run of chains 75 and may be adjustable vertically in any conventional manner for adjusting the tension of the chains 75. The sprocket pairs on each of the shafts 78, 79 and 81 are keyed or fixed to their ~respeetive shafts so that they rotate in unison. Each of the chain members 75 has a plurality of spaced outwardly extending dogs 84 affixed thereto. The dogs 84 are uniformly spaced;a-long each chain 75 and are parallel to the dogs of the mating chain 75. As best seen in Figure 3, the spacing of the dogs is such as to encompass the approximate di.stance between each of the feed stations 16a through 16e so that as plates or separa-tors from stations 16a through 16e are dropped through apertures 33a through 33e in the base plate 22, they are deposited on the .

Z~Z
chains 75 b~tween a pair of dogs 84 to form books of alternating layers of plates and separators. As seen in Figures 3 and 9, beneath each of the apertures 33a, 33c, and 33e of feed stations 16a, 16c, and 16e, three parallel, spaced and generally horizon-tally extending tines 86 are located. The upstream ends of each of the tines 86 has an upwardly extending portion which is at-tached in any suitable manner to the bottom of base plate 22.
Each of the sets of tines 86 extends beneath the eed stations 16a, 16c and 16e to catch the relatively fragile negative or posi-tive battery plates Nl, N2 or P. The position of the tines 86 is such that dogs 84 moving with chains 75 pass between the outer and inner tine projections and strip the deposited battery pla~Ps off the tines whereby the plates then drop down unto the conveyor chains 75 between the respective dogs 84. A pair of spaced verti-cal guidewalls 88 also extend beneath the base plate 22 on either side of the chains 75 and prevent lateral motion of the stacked plates off of ~he chains 75. As the conveyor chains 75 move downstream and pass beneath the final feed station 16e, an up-wardly inclined ramp 90 is provided which extell~s between chains 75. As the dog~ 84 push the books along the chains 75, the books will be pushed upwardly along the inclitled ramp 90 to the point where the upper extremeties of the dogs 84 passbeneath the line of intersection of ramp 90 whereby the books are stationarily supported on ramp 90 for pickup by ferris wheel assembly 12 as will be described hereinafter. A pair of inclined vertical guide-walls 92 may be provided on either side of the inclined ramp 90 and chains 75 exteriorly of the.support plate 22. The guide plates 92 may also each include an inclined portion 93 which may . ' ..
~(:i 7~
extend parallel to inclined ramp 90, however, both the guide plates 92 and the adjoining portions 93 termina~e at a point prior to the final resting position of the books on the inclined ramp 90 to provide clearance for the ferris wheel assembly 12.
As is also seen in Figure 3, downwardly extending leaf springs 95 may be provided beneath plate 22 adjacent the down-stream ends of stations 16b and 16d. The leaf springs 95 are pivo~ally attached to ~he plate 2~ by any suitable means such as pivot pins 96, and tension springs 97 may be attached between the bottom of plate 22 and a portion of leaf springs 95~ to re-siliently urge the springs 95 into an approxima~ely vertically downwardly extending position. As seen in Figure 3, the springs 95 will act upon the forward edge of the separators Sl and S2 and urge them rearwardly into contact with the following dog 84 on chain~ 75 thereby insuring alignment of the separators and plates of the books on the chains 75. The leaf members 95 need not be provlded at the battery plate feed stations since the battery plate~ are ~tripped from.the tines 87 by dogs 84 and will be in general alignment with the edge of the trailing dog 84 on chain 75. As is also seen in Figure 3, beneath the stations 16a through 16e and also beneath chains 75, an open topped gener-ally rectangular chamber 100 is located for receiving particles of battery pas~e and other foreign matter which might drop down from the chain 75. To facil~tate removal of .such foreign matter, especlally the battery dust which can be harmful to workers if inhaled, a vacuum tube 101 is attached at one or more locations along the bottom of the chamber 100 for drawing the loose par~i-cles out of the chamber 100 and away from the apparatus. The vacuum tube 101 may be connected to any suitable source of vacuum in a conven~ional and well known manner. Addi~ionally, a photo-electric eye 102 is mounted on one end of the loading station 10 and an aligned reflector 103 on the opposite end is pro~ided for detecting jams or misaligned plates beneath the base plate 22.
The drive appara~us 25 is seen in Figures 3 and 4 and in-cludes a prime mover for providing power to turn the oonveyor .chains 75 and other parts of the system to be descrlbed herein-after. The prime mover is supported on the framework 23 and may be any conventional motive means such as an electric motor 105.
' The motor 105 has an output shaft 106 with a pulley 107 attached thereto which drives a pulley 108 attached ko shaft 109 of a gear reducer unit llO by means of a drive belt 111. The output shaft 112 of reducer 110 has a sprocket 113 attached thereto and a chaln 114 couples sprocket 113 to a second sprocket 115 attach-ed to a power shaft 116. Power shaft 116 extends generally hori-zontally along framework 23 and may be suitably journaled for rotation in bearings 117. A drive gear 120 is attached to shaft 116 for rotation therewith, and a clutch unit 121 is provided itl shaft 116 between sprocket 115 and drive gea,.r 120 or selectively engaging ~nd disengaging the drive motor 105 with drive gear 120.
A power output shaft 125 i8 coupled to output gear 120 by means of a msting g0ar 126, and ~haft 125 may also be suitably journaled in bearings 127. A pLurality of sprockets 130-133 are afixed to shaft 125 for providing power to the ,apparatus in a manner to be described hereinafter. Sprocket 130 is coupled to a drive sprocket 135 attached to shaft 79 of the conveyor belt 75 by means ~6zo~ ~74~7 of a drive chain 136. Similarly, sprockets 131-133 are each associated with drive chains 137-139 respectively.
Drive chain 137 drlves a series of cams 140-145 contained in a control box 147. The drive chain 137 engage~ a sprocket 148 attached to a right angle gear drive 149 whos~ output sprocket 150 is coupled by a drive chain 151 with a sprocket 152 atta~hed to cam shaft 153 to which cams 140-145 are attached. Cam shaft 153 may be rotatably journaled in bearings 154 within the control box 147. ~ach of the cams 140-145 actuate a correspo~ding switch (not shown) for controlling the appara~us in a manner which will be described hereinafter.
Drive chains 138 and 139 are adapted to drive the ferris wheel assembly 12 and output conveyor 14 respectively. Ferris wheel assembly 12 and output conveyor 14 are depicted generally in Figure 1. In the preferred embodimPnt, the ferris wheel 12 and output conveyor 14 are similar to those described in U.S.
patent 2,897,950 to L. G. Reed, issued on August 4, 1959. The ferris wheel 12 and output conveyor 14 are thus well known to those skilled in the art and need not be described in deta;l.
It will suffice to say that the ferris wheel 12 is adapted to pick up the books from inclined ramp 90 shown in Figure 3 and transfer them to a holding station 155 ad~acent output conveyor 14. The ferris wheel may be adapted to orm the books into elements at the holding station 155 prlor to transfer to the moving conveyor belt (not shown) of the output conveyor apparatus 14 for further processing. Other suitable transfer mechanisms could be utilized with the invention às will be apparene to those skille'd in the art.

Any con~en-tional source of pressurized fluid ma~ be provided for selective-~y actuating cylinder 165, and plate 22 may be hinged at its rear edge for pivotally raising and lowering plate 2~.
As previously mentioned, conventional practice in the battery making field has been to ~orm battery elements having one more ~`
negative plate than the number of positive plates. Therefore, assuming a nine plate battery element is ~o be produced on the apparatus according to the invention, the element will be composed of ~our books. Each of three books will con~ist o a negative plate Nl, a separator Sl, a positive plate P, and a separator S2.
The fourth book will include the same plate arrangement plus an additional N2 negative plate on the top of the book. The first three books are formed on the loading station 10 and are then transferred by the ferris wheel assembly 12 to the holding s~ation 155 of the outp~t conveyor apparatus 14 where they are combined.

The controls necessary for enabling the present invention to function in the manner just described are schematically depicted in Figures 10 through 12. Figure 10 schematicaLly depicts the circuits for the drive motor lQ5 and a motor 170 for driving a vacuum pump 171. A start switch 172 is provided for activating a motor s~art relay 173 coupled to start up circuit 174 of the motor 170. A stop switch 175 is also provided for manually re-setting the relay 173 to stop the motor 170. The second start switch 176 recelves power only when relay 173 is activated and is coupled to a start relay 177 coupled to start circuit 178 of the mechanical drive motor lOS. Relay 174 may be reset to a stop position by either stop switch 179 or by a signal from photocell 102 in the event of a jam on the conveyor chains 75. Drive motor 105 may also be stopped by action of a limit switch 180 which may be coupled to the conveyor assembly 14 and which is activated ? when the conveyor is full to prevent an excessive build up of elements on the convey~r 14. Limit switch 180 may be coupled to a switch 181 which closes when switch 180 opens to activate an indicator light 182 for visually indicating that the conveyor 14 iS ~ull.

. A74-7 ~7~i2~2 The circuit is controlled by cams 140-145 contained in the con-trol box 147 which are driven by the drive motor 105 Cam 140 acts upon a switch 190 to provide impulse signals to a first counter 191. The first counter 191 may have a manual selector, not shown, for providing an output pulse after a predetermin~d number of impulses from the switch 190. The output pulse from the first counter 191 activates a pair of relays 192 and 193.
Activation of relay 192 penmits cam 145 to activate a switch 194 for energizing a solenoid 195 for controlling the depositing of the N2 negative plates on the conveyor 75. As soon as cam 145 activates switch 194, cam 141 acts upon a switch 196 which resets the relay 192. Relay 193 when activated perrnits s~.7itch ].98 which is activated by cam 142 to provide input pulses to A second counter 200 which controls the timing of the transfer of elements from the holding station 155 to output conveyor assembly 14 after a completed element is formed. The counter 200 sfter a pre-determined number of input impulses, sends an output pulse to relay 20t which energizes a transfer control mechanism 202 to initiate transfer of the elements from the holding station 155 to the outpu~ conveyor 14. Shortly thereafter, cam 143 activates a switch 203 which resets relay 201. During the foregoing functions, , cam 1~4 controls a switch 205 which energizes solenoids 206-209 which in turn control the depositing of Nl negative plates, posi-tive plat~s P, and`separator elements Sl and S2 from stations 16a through 16d.
Referring now to Figure 12, the control system for cylinders 43a-43e which activate~discs 30a-30e and control the depositing . , .

of separator plates and battery plates on the conveyor chains 75 is shown. Solenoids 206-209, when activated or deactivated by cam 144 and switch 205, direct pressurized fluid from a source 210 to one of the two ends of the cylinders 43a through - 43d for pivoting disc plates 30a through 80d. The fluid could be air or hydraulic fluid or any other suitable fluid and may be directed into ~he cylinders through a filter 211 and an oiler 212 in the event the fluid is compressed air. ~ylinder 43e is activated by solenoid 195 through cam 145 and switch 194 in a similar manner to control the deposition of the N2 negative plates on the conveyor chains 75 at the appropriate time.
OPERATION OF THE INVENTION
Having described the physical arrangement of components of the apparatus according to the invention, the operation of the device will now be described. For the sake of illustration, it will be assumed that a nine plate battery element is to be fonmed.
Such an element wouLd contain five negative plates and four posi-tive plates all separated by nonconductive separators, Thus, each battery element would consist of four books of plates and separa-tors with the additional inclusion of one N2 plate in the final book. 'l'hc first counter 191 is thus set to produce an output pulse af~er four counts from switch 190. Second counter 200 is set to deliver an output pulse after three complete books plus t~e fourth book containing the extra negative plate are deposit-; ed on the holding station 155 adjacent output conveyor assembly 14. The setting of counter 200 will depend ùpon the number of pickup arms contained in the ferris wheel assembly ~12~. For~ex-~
- ~8 -..
~ ~ 7 ~ Z ~ Z
ample, if the ferris wheel contains six arms9 counter 200 would be activated, after each two-thirds of a revolution of the ferr~s wheel 12.
- After setting the counters 191 and 200, switch 172 is closed to start the blower motor 170 and switch 176 is closed to start the conveyor drive motor 105. Clutch 121 is then engaged to connect the drive motor 105 through power shaft 116 to shaf~ 125 carrying the drlve sprocket 130 through 133 thereby driving the conveyor chains 75, the ferris wheel assembly 12, the conveyor assembly 14, and the timing cams 140-145 mounted on shait 153.
As cam shaft 153 rotates; solenoids 206-209 are energlzed thereby actuating cylinders 43a through 43d for simultaneously depositing the Nl, Sl, P and S2 elements on conveyor belt 75. As conveyor chains 75 move bèneath base plate 22, the books will be formed a~ illustrated in Figure 3 progressively obtaining a negative plate, a separator Sl, a positive plate and a separator S2. At the fourth count, counter 191 will activate relay 192 which will be activated by cam 145 to deposit an N2 negative plate on top of the fourth book. The books will be successively driven by con-veyor cha~n 75 up th~ ramp 90 where they wlll be 3uccessively picked up by the ferris wheel assembly 12 and deposited at the holding station adj:acent conveyor 14 until the requisitenumber of books 8re deposited to form a completed element. After the re-quired number of books have been placed at the holding station~
the second counter 200 activates relay 201 which wil~ in turn activate the transfer mech~nism 202 for transferring the~ completed element onto output conveyor~ assembly 14 for further processing.

It will be appreciated that photbcell 102 will automatically stop the conveyor drive motor 105 in the event of any fouling beneath the base plate 22 of loading station 10. To clear a jam, cylinder 165 may be activated to pivotally lift the base plate 22 to provide access to the interior of the loading station 10.
The present apparatus has been ~ound to be operable at stacking rates approximately twice as fast as conventional stack-ers for battery plates. While one embodiment 3f ,the invention has thus been described, it will be appreciated by those skilled in the ~rt that other variations are possible without departing from the nature of the invention. Accordingly, the invention is not to be limited by the foregoing description but is to be taken solely by an interpretation of the claims which follow.

BACKGROUND OF THE INVENTION
In the manufacture of storage batteries, particularly lead-acid type storage batteries, one or more elements are provided within a battery case containing el~ctrolyte. The elements generally comprise a plurality of alternately positive and neg-ative battery plates each separated by a sheet of insulating material commonly referred to as separators. The battery plates each typically comprise a relatively fragile supporting grid having a lead paste applied thereto. Conventional practice has been to form the battery elements so as to have one more negative plate than the number of positive plates so ~hat the end most plates of each element are negative plates. The battery elements will thus contain an odd number of plates whic~l may vary from as low as five plates on up to 25 plates depending on the desired capacity of the storage battery.
Various devices have been provided for assembling battery plates and separators into elements automatically to eliminate stacking by hand. Such devices have generally operated in one of two broad catagories. The Eirst catagory utilizes a top lift system as seen in U.S. Patent No. 2J790~536 issued April 30, 1957, to Reed; and U.S~ Patent No. 2~830,692 issued April 15, 1958 to Winkel. In the top lit arrangement, vacuum type suction devices or mechanical means are usually provided to lift individual bat-tery plates and separators from the tops of feed stacks and ar-range them înto alt~rnating battery elements. While thP top lift system provides or ease in transferring thin, fragile separators and battery plates, movement through relatively large distances l~ .
,. '' ' ~ '.
.
\
-~ A74-7 :~76~C~2 is generally required thereby reducing the speed at which systems can operate.
The second catagory of battery element forming apparatus utilize a bottom shuttle system in which individual plates or separators are stripped from the bottoms of stacks of feed stacks and deposited into battery elements. Examples of the shuttle type devices are seen in U.S. Patents No. 2,897,950 issued August 4, 1959 to Reed; 29624,106 issued January 6, 1953 to Lund; 2,652,933 issued Septem~er 22, 1953 to Willard et al; 2,807,227 issued September 24, 1957 to Kerns et al; and 2,908,377 issued Oc~ober 13, 1959 to Winkel et al. In the shuttle type devices, a pusher plate is generally provided for stripping a battery plate or separator by pushing motion parallel to the plane of the plate or separator.
The disadvantage of this type of arrangement rests in the fact that the plates and separators are relatively fragile and are easily buckled during such pushing motion thereby often causing jams and disrupting the stacking process. A further disadvantage of this type of system is that the weight of the remaining members of the feed stack, from which the lower-most elèment is stripped, bears down upon the moving lower plate resulting in abrasive and frictional forces between the surfaces of the adjacent stationary member and the moving plate or separator. Attempts have been made to reduce such frictional forces, however, the shuttle type systems are generally limited in the speed at which they can be operated.
SUMMARY OF THE INVENTION
The present invention basi~ally comprises an apparatus ~or forming battery eLements of positive and negative battery plates .
~ ~ 7 ~ Z ~ 2 and separator. The apparatus generally in~ludes a loading plat-form having a plurality of feed stations on which separate feed stacks of positive plates, negative plates, and separators are supported on rotatable discs. ~ach rotatable disc has an aper-ture conforming to the configuration of the individual plate or separator and the disc may be rotated to align the aperture with a similar aperture formed in a support platorm for deposit-ing individual plates or separators onto a moving conveyor belt.
Fixed guides are provided at each station for maintaining the individual feed stacks in a rotatably fixed position over the discs while allowing the feed stacks to move downwardly by gravi-tational force into contact with the aperture of the rotatable disc. Upon successive reciprocal rotation of the disc, single plates or separators are directed from the bottom of the feed stacks through the apertures in the discs and the apertures in the platform down onto the conveyor to form books of plates and separators which are combined to form elements. Controls are provided for varying the configuration of the various elements formed after removal from the conveyor belt.
It is an object of the invention to provide an improved apparatus for assembling ba~eery elements.
A further object of the invention is to provide an apparatus for assembling battery plates and separators by stripping a plate or separator from the bottom of a feed stack by rotating the lower-most plate or separator relative to the remaining feed stack mem-bers.
Another object o the invention is to provide an apparatus :~G97~
stripping battery plates or separators from a feed stack with reduced slid-ing contact.
According to the broadest aspect of the prese~t invention, there is provided feed apparatus for dispensing battery plates or separators from a stack supported from the underside of the lower-most member of said stack, said apparatus comprising means for maint~ining a stack of plates or separa-tors in a horizontally fixed position over means for receiving said plates and separators, means for pivoting the lower-most member of said stack be-tween a first position in alignment with the remaining stack members and a second position axially aligned with the remaining s~ac~ memb~rs but rotation-ally displaced therefrom, and means for permitting said lower-most member to be deposited on said receiving means from said second position.
The invention will now be described in greater detail with refer-ence to the accompanying drawings, in which.

for arrangement into elements of alternating plates and separa-tors, a ferris wheel type transfer device 12 for removing books from the loading station 10 and for placing them on an output conveyor unit 14 for removing the elements for further processing.
With reference to Figures 1 through 3, ~he loading station 10 is seen to compris a plurality of individual stack feed stations 16a - 16e supported on a base plate 22 w~ich in turn is supported on a sui~able framework 23. A dual strand conveyor assembly 24 is supported within the framework ~3 benea~h the base pla~e 22 for receiving individual battery plates and separ-~ ~--h ~
, ~t, ators in a~m~ to be described hereinafter. A drive assembly ~, 25 is also supported within the framework 23 for providing motive power to the conveyor assembly 24 and other components of the apparatus as will be described later.
Referring generally to Figures 1, 2, 3 and 5, the construction of the feed stations 16a through 16e will now be described. Since each of the individual feed stations 16a through 16e are identical-ly constructed, only one need be described in detail, and like parts are designated by like numbers with subscripts a ~ e as appropriate. Feed station 16d includes a circular disc 30d having a generally rectangul~ar shaped aperture 31d formed in its central portîon. The disc 30d is supported,on the top of the base plate 22 which has a similarly shaped rectangular aperture 33d fornled therein. With particular reference to Figures 5 and 8, the plate 30d is rotatably affixed to the top surface of b~se plate 22 by a plurality of bearing assemblies 35d spaced around the periphery of disc 3Vd. Each bearing assembly 35d may consist of generally ~ ~ ~ 6 2 ~ Z
L-shaped bracket 37d ha~ing one leg extending in spaced relation-shlp above the edge of the upper surface of plate 30d. One or more rollers 38d may be provided between the brackat extension and the top surface o~ disc 30d for rollably engaging the upper surface of disc 30d. Similar rollers 39d may be provided between the peripheral edge of di~c 30d and a downwardly extending inner portion o bracket 37d. Bracket 37d may be secured ~o the base plate 22 by conventional means such as bolts 40d. Adjusting shims 41d may be provided between the adjoining surfaces of brack-et 37d and base plate 22 for adj usting the bearing load of bear-ings 38d. It will thus be ~een tha~ the disc 30d is vertically and horizontally fixed relative to base plate 22 by the bearing assemblies 35d, but the disc 30d is free to rotate within the con~ines of bearing 35d. Thu~, the disc 30d can be rotated to position aperture 31d into and out of alignment with aperture 33d formed in the base plate 22. The rotation oi disc 30d may be provided by a double acting fluid cylinder 43d which extends generally horizontally along the upper surface of base plate ~2, Cylinder 43d may include an extensible shaft 44d having a clevis 45d which is pivotally connected to a pivot pin 46d extending from the plate 30d. The opposite end of cylinder 43d may have a clevis 48d secured to a pin 49d fixed to base plate 22. Cyl-inder 43d may be of any suita~le fluid actuated type such as air or hydraulic and has a pair of ~luid conducting lines 50d and 51d connected thereto in a conventional manner fur ac~uating cylinder 43. Lines 50d and 51d may be coupled to a suitable sour~e of pres~urized ~luid. (not shown) ~ 6 --- . .... . : ~ .

As shown in Figures 5, 6 and 7, feed station 16d also in-cludes a pair of spaced, vertically extending angle brackets 55d . and 56d which engage diametrically opposed corners of a stack of separators S2. Angle brackets 55d and 56d are each supported by a block 58d attached to base plate 22 outside the confines disc 30. Generally horizontally extending rods 60d may be attached to each of the angle brackets 55d and 56d and the rods 60d may extend throu~h apertures 61d formed,in blocks 58d. An adjusting screw 62d will be provided in the side of each block 58d in com-munication with the aperture 61d for frictionally engaging rod member 60d for adjusting the vertical and horizontal positions of angle brackets 55d and 56d. Brackets 55d and 56d are each adj.usted horizontally to slidingly engage the opposed corners of the horizontal stack of separators S2, and are vertically adjusted to provide a small clearance space between the lower portion of the brackets 55d and 56d and the upper surface of disc 30d.
As seen in Figures,5 and 6, when the aperture 31d o~ disc 30d i. positioned so as to aline the opposite corners of aper-ture 31d with the position of the stack o~ separators S2, the lower-most member of the stack will be guided by brackets 55d .
and 56d into the aperture 31d of disc 30d. Further motion of the stack members will be limited by engagement of the lower-most member with the upper surface of base plate 22. The thickness of disc 30d in the region beneath brackets 55d and 56d will be approxima~ely equal to the thic~ness of the separators S2 so that only one separator will be contained within aperture 31d ~ 7 --.
~7~
of disc 30d. The p2riphery of the disc 30d may have increased thickness if necessary to reduce warping or deflection of the disc during rotation. To further influence the downward motion of the lower-most separator member, a plurality of apertures 65d are provided in base plate 22 at a position in alignment with the corners of the staek of separators S2 such that the aper-tures 65d are exposed within aperture 31d when disc 30d is posi~
tioned to align the aperture 31d with the separators S2. A
manifold 66d is provided along the bottom portion of plate 22 and extends around the exterior of aperture 33d formed in the base plate 22 and has its interior communicating with each of the apertures 65d. A suitable high vacuum line 67d may connect the interior of manifold 66d with a suitable source of vacuum ~hereby creating a suction at each of the apertures 65d tending to draw the lower-most separator S2 downwardly into aperture 31d of disc 30d.
From the foregoing description, it will be appreciated that when cylinder 43d is actuated to position disc 30d with its aper-ture 31d in general alignment with the stack of separators S2, the lower-most separator will be drawn both by gravity and vac- :
uum into the aperture 31d of the disc 30d with further motion o:E the se~rator limited ~y support of its corners on the exposed portions of base plate Z2. Actuation of the cylinder 43d to ro-tate disc 30d so as to position aperture 31d in alignment with aperture 33d will resuLt in the pivotîng of the lower-most separ-ator 5Z contained within aperture 31d into alignmen~ with aper-ture 33d of the base plate 22. The separator will then fall :~716~
through aperture 33d of base plate 2~ under the influence of gravity alone. Rotation of the disc 30d will also result in closure of the vacuum apertures 65d by moving aperture 31d out of position over the apertures 65d. It will also be appreciated that the angle brackets 55d and 56d will restrain the remaining separator stack members S2 from pivotal motion with disc 30 thereby effectively resulting in a stripping of the bottom separator S2 from the stack with ultimate deposit through aper-ture 33d of the base plate 22. Recycling of the cylinder 43d and disc 30d will provide a similar stripping action as to the remaining separators S2. It will also be apparent that the amount of sliding contact between the pivoting lower-most separator and the adjacent separator is signîficantly less than that present in conventional shuttle type systems.
As seen in Flgures 1 through 3, the separate feed stations 16a through 16e are arranged in a line along the top of base plate 22 and each contain a stack of similar battery plates or separators. Station 16a is provided with a stack of negati~e plates designated as Nl, station 16b contains separators desig-nated as Sl, station 16c contains positive plates designated as P, sta~ion 16d contains separators designated as S2, and station 16e contains a stack of negative plates designated as N2. Each of the feed stations is constructed in a manner simi-lar to that of feed atation 16d with the exception that the /~1 Ibc ~Qd /~e A battery plates at stations ~6~ 24-are of generally sufficient mass to enable the elimination of vacuum apertures 65d, manifold 66d and vacuum lin~ ~7d provided for the separators which are gen~

Conveyor assembly 24 is located beneath the base plate 22 within f~amework 23 for gathering books oi plates and sep-arators and is best seen in Figures 3 and 9. Conveyor assem-bly 24 generally comprises a pair of parallel endless chains 75 which are arranged to have a substantially horizontally extend-ing run beneath ~he base plate 22 of the loading station 10.
The opposite ends o~ the parallel chains 75 are supported on a first pair of sprockets 76 located at the end of base plate 22 adjacent station 16a, and a second pair of sprockets 77 located ~t the opposite end of the loading station 10. Sprocket pairs 76 and 77 may be supported on horizontal shafts 78 and 79 respectively which may be journaled in bearings (not shown) in any conventional manner. A third sprocket pair 80 may be simi-larly iournaled on a shaft 81 beneath the upper run of chains 75 and may be adjustable vertically in any conventional manner for adjusting the tension of the chains 75. The sprocket pairs on each of the shafts 78, 79 and 81 are keyed or fixed to their ~respeetive shafts so that they rotate in unison. Each of the chain members 75 has a plurality of spaced outwardly extending dogs 84 affixed thereto. The dogs 84 are uniformly spaced;a-long each chain 75 and are parallel to the dogs of the mating chain 75. As best seen in Figure 3, the spacing of the dogs is such as to encompass the approximate di.stance between each of the feed stations 16a through 16e so that as plates or separa-tors from stations 16a through 16e are dropped through apertures 33a through 33e in the base plate 22, they are deposited on the .
., , . . - - . :
.. ~ . .
Z~Z
chains 75 b~tween a pair of dogs 84 to form books of alternating layers of plates and separators. As seen in Figures 3 and 9, beneath each of the apertures 33a, 33c, and 33e of feed stations 16a, 16c, and 16e, three parallel, spaced and generally horizon-tally extending tines 86 are located. The upstream ends of each of the tines 86 has an upwardly extending portion which is at-tached in any suitable manner to the bottom of base plate 22.
Each of the sets of tines 86 extends beneath the eed stations 16a, 16c and 16e to catch the relatively fragile negative or posi-tive battery plates Nl, N2 or P. The position of the tines 86 is such that dogs 84 moving with chains 75 pass between the outer and inner tine projections and strip the deposited battery pla~Ps off the tines whereby the plates then drop down unto the conveyor chains 75 between the respective dogs 84. A pair of spaced verti-cal guidewalls 88 also extend beneath the base plate 22 on either side of the chains 75 and prevent lateral motion of the stacked plates off of ~he chains 75. As the conveyor chains 75 move downstream and pass beneath the final feed station 16e, an up-wardly inclined ramp 90 is provided which extell~s between chains 75. As the dog~ 84 push the books along the chains 75, the books will be pushed upwardly along the inclitled ramp 90 to the point where the upper extremeties of the dogs 84 passbeneath the line of intersection of ramp 90 whereby the books are stationarily supported on ramp 90 for pickup by ferris wheel assembly 12 as will be described hereinafter. A pair of inclined vertical guide-walls 92 may be provided on either side of the inclined ramp 90 and chains 75 exteriorly of the.support plate 22. The guide plates 92 may also each include an inclined portion 93 which may . ' ..
~(:i 7~
extend parallel to inclined ramp 90, however, both the guide plates 92 and the adjoining portions 93 termina~e at a point prior to the final resting position of the books on the inclined ramp 90 to provide clearance for the ferris wheel assembly 12.
As is also seen in Figure 3, downwardly extending leaf springs 95 may be provided beneath plate 22 adjacent the down-stream ends of stations 16b and 16d. The leaf springs 95 are pivo~ally attached to ~he plate 2~ by any suitable means such as pivot pins 96, and tension springs 97 may be attached between the bottom of plate 22 and a portion of leaf springs 95~ to re-siliently urge the springs 95 into an approxima~ely vertically downwardly extending position. As seen in Figure 3, the springs 95 will act upon the forward edge of the separators Sl and S2 and urge them rearwardly into contact with the following dog 84 on chain~ 75 thereby insuring alignment of the separators and plates of the books on the chains 75. The leaf members 95 need not be provlded at the battery plate feed stations since the battery plate~ are ~tripped from.the tines 87 by dogs 84 and will be in general alignment with the edge of the trailing dog 84 on chain 75. As is also seen in Figure 3, beneath the stations 16a through 16e and also beneath chains 75, an open topped gener-ally rectangular chamber 100 is located for receiving particles of battery pas~e and other foreign matter which might drop down from the chain 75. To facil~tate removal of .such foreign matter, especlally the battery dust which can be harmful to workers if inhaled, a vacuum tube 101 is attached at one or more locations along the bottom of the chamber 100 for drawing the loose par~i-cles out of the chamber 100 and away from the apparatus. The vacuum tube 101 may be connected to any suitable source of vacuum in a conven~ional and well known manner. Addi~ionally, a photo-electric eye 102 is mounted on one end of the loading station 10 and an aligned reflector 103 on the opposite end is pro~ided for detecting jams or misaligned plates beneath the base plate 22.
The drive appara~us 25 is seen in Figures 3 and 4 and in-cludes a prime mover for providing power to turn the oonveyor .chains 75 and other parts of the system to be descrlbed herein-after.

The cylinder may be pivotally attached to frame 23 by pins 166 and an extensible shaft 167 may be pivotally attached to base plate 22 by a pin 168. Any con~en-tional source of pressurized fluid ma~ be provided for selective-~y actuating cylinder 165, and plate 22 may be hinged at its rear edge for pivotally raising and lowering plate 2~.
As previously mentioned, conventional practice in the battery making field has been to ~orm battery elements having one more ~`
negative plate than the number of positive plates. Therefore, assuming a nine plate battery element is ~o be produced on the apparatus according to the invention, the element will be composed of ~our books. Each of three books will con~ist o a negative plate Nl, a separator Sl, a positive plate P, and a separator S2.
The fourth book will include the same plate arrangement plus an additional N2 negative plate on the top of the book. The first three books are formed on the loading station 10 and are then transferred by the ferris wheel assembly 12 to the holding s~ation 155 of the outp~t conveyor apparatus 14 where they are combined.

Relay 174 may be reset to a stop position by either stop switch 179 or by a signal from photocell 102 in the event of a jam on the conveyor chains 75. Drive motor 105 may also be stopped by action of a limit switch 180 which may be coupled to the conveyor assembly 14 and which is activated ? when the conveyor is full to prevent an excessive build up of elements on the convey~r 14. Limit switch 180 may be coupled to a switch 181 which closes when switch 180 opens to activate an indicator light 182 for visually indicating that the conveyor 14 iS ~ull.

. A74-7 ~7~i2~2 The circuit is controlled by cams 140-145 contained in the con-trol box 147 which are driven by the drive motor 105 Cam 140 acts upon a switch 190 to provide impulse signals to a first counter 191. The first counter 191 may have a manual selector, not shown, for providing an output pulse after a predetermin~d number of impulses from the switch 190. The output pulse from the first counter 191 activates a pair of relays 192 and 193.
Activation of relay 192 penmits cam 145 to activate a switch 194 for energizing a solenoid 195 for controlling the depositing of the N2 negative plates on the conveyor 75. As soon as cam 145 activates switch 194, cam 141 acts upon a switch 196 which resets the relay 192. Relay 193 when activated perrnits s~.7itch ].98 which is activated by cam 142 to provide input pulses to A second counter 200 which controls the timing of the transfer of elements from the holding station 155 to output conveyor assembly 14 after a completed element is formed. The counter 200 sfter a pre-determined number of input impulses, sends an output pulse to relay 20t which energizes a transfer control mechanism 202 to initiate transfer of the elements from the holding station 155 to the outpu~ conveyor 14. Shortly thereafter, cam 143 activates a switch 203 which resets relay 201. During the foregoing functions, , cam 1~4 controls a switch 205 which energizes solenoids 206-209 which in turn control the depositing of Nl negative plates, posi-tive plat~s P, and`separator elements Sl and S2 from stations 16a through 16d.
Referring now to Figure 12, the control system for cylinders 43a-43e which activate~discs 30a-30e and control the depositing . , .
~76;~ Z
of separator plates and battery plates on the conveyor chains 75 is shown. Solenoids 206-209, when activated or deactivated by cam 144 and switch 205, direct pressurized fluid from a source 210 to one of the two ends of the cylinders 43a through - 43d for pivoting disc plates 30a through 80d. The fluid could be air or hydraulic fluid or any other suitable fluid and may be directed into ~he cylinders through a filter 211 and an oiler 212 in the event the fluid is compressed air. ~ylinder 43e is activated by solenoid 195 through cam 145 and switch 194 in a similar manner to control the deposition of the N2 negative plates on the conveyor chains 75 at the appropriate time.
OPERATION OF THE INVENTION
Having described the physical arrangement of components of the apparatus according to the invention, the operation of the device will now be described. For the sake of illustration, it will be assumed that a nine plate battery element is to be fonmed.
Such an element wouLd contain five negative plates and four posi-tive plates all separated by nonconductive separators, Thus, each battery element would consist of four books of plates and separa-tors with the additional inclusion of one N2 plate in the final book. 'l'hc first counter 191 is thus set to produce an output pulse af~er four counts from switch 190. Second counter 200 is set to deliver an output pulse after three complete books plus t~e fourth book containing the extra negative plate are deposit-; ed on the holding station 155 adjacent output conveyor assembly 14. The setting of counter 200 will depend ùpon the number of pickup arms contained in the ferris wheel assembly ~12~. For~ex-~
- ~8 -..
~ ~ 7 ~ Z ~ Z
ample, if the ferris wheel contains six arms9 counter 200 would be activated, after each two-thirds of a revolution of the ferr~s wheel 12.
- After setting the counters 191 and 200, switch 172 is closed to start the blower motor 170 and switch 176 is closed to start the conveyor drive motor 105. Clutch 121 is then engaged to connect the drive motor 105 through power shaft 116 to shaf~ 125 carrying the drlve sprocket 130 through 133 thereby driving the conveyor chains 75, the ferris wheel assembly 12, the conveyor assembly 14, and the timing cams 140-145 mounted on shait 153.
As cam shaft 153 rotates; solenoids 206-209 are energlzed thereby actuating cylinders 43a through 43d for simultaneously depositing the Nl, Sl, P and S2 elements on conveyor belt 75. As conveyor chains 75 move bèneath base plate 22, the books will be formed a~ illustrated in Figure 3 progressively obtaining a negative plate, a separator Sl, a positive plate and a separator S2. At the fourth count, counter 191 will activate relay 192 which will be activated by cam 145 to deposit an N2 negative plate on top of the fourth book. The books will be successively driven by con-veyor cha~n 75 up th~ ramp 90 where they wlll be 3uccessively picked up by the ferris wheel assembly 12 and deposited at the holding station adj:acent conveyor 14 until the requisitenumber of books 8re deposited to form a completed element. After the re-quired number of books have been placed at the holding station~
the second counter 200 activates relay 201 which wil~ in turn activate the transfer mech~nism 202 for transferring the~ completed element onto output conveyor~ assembly 14 for further processing.

It will be appreciated that photbcell 102 will automatically stop the conveyor drive motor 105 in the event of any fouling beneath the base plate 22 of loading station 10. To clear a jam, cylinder 165 may be activated to pivotally lift the base plate 22 to provide access to the interior of the loading station 10.
The present apparatus has been ~ound to be operable at stacking rates approximately twice as fast as conventional stack-ers for battery plates. While one embodiment 3f ,the invention has thus been described, it will be appreciated by those skilled in the ~rt that other variations are possible without departing from the nature of the invention. Accordingly, the invention is not to be limited by the foregoing description but is to be taken solely by an interpretation of the claims which follow.
