APPARATUS FOR LINING DRY CELLS.

. Application filed May 10, 1913.

T 0 all whom it may concern Be it known that I, Loozs E. IVILLIAMS, a citizen of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented a certain new and useful Improvement in Apparatus for Lining Dry Cells, of which the following is a full, clear, and exact description.

This invention relates to apparatus for lining containers, more particularly dry cel s.

The usual method of procedure in making dry cells is to insert the bibulous lining and bottom disks manually in the zinc container, no machinery whatever being used.

The object of my invention is to devise a machine for accomplishing the same results rapidly and automatically.

Other objects will appear in the following description.

Figure 1 is a front view of a can lining machine. Fig. 2 is a cross-sectional view of a dry cell after the lining and disks'have been inserted. Fig. 3 is an end view of Fig. 1 taken from the left, certain parts being omitted. Fig. 4 is an isometric projection of the can feeding mechanism. Fig. 5 is a cross-sectional view on the line AA of Fig. 1 lookng toward the right, showing the driving means. Fig. 6 is a cross-sectional view on the line BB of Fig. 1 also looking toward the right, certain parts being omitted. Fig. 7 is a cross-sectional view on the line CC of Fig. 1 looking toward the right, with certain parts omitted. Fig. 8 is an enlarged partial cross-sectional view taken on the line D-D of Fig. 1. Fig. 9 is a partial cross-sectional view of the rolling mechanism for inserting the lining.

this support, a. toothed sprocket Wheel 5 is fastened by bearings 6. The teeth of the sprocket wheels 5 extend through a slot 7 in the ends of the support 4 and engage an endless chain or conveyer 8. To the endless chain 8 are attached in any convenient manner. a number of cylindrical holders 9, into which the zinc cans 10 of the dry cell are placed. These holders are arranged'equidistant along the endless chain and have a height somewhat less than the height of the can 10.

At the right hand side of the apparatus, as shown in Fig. 1, the upright members 11 are joined by the cross pieces 12 at the top and bottom (Fig. A shaft 13 is supported in bearing 14: resting on the upper cross-piece 12. Other bearings are provided .at the other points along the shaft. A pulley 15 is fastened to the shaft 13 and is driven by any source of power, a belt 16 being shown. The shaft 13 rotates the shaft 21 by means of gears 18, 19 and 20. A mutilated gear 22, keyed on shaft 21 meshes with the pinion 23 on the shaft 17 and thus turns it intermittently. In order to support the train of gearing, a pair of uprights 24 and 25 shorter than uprights 11 may be provided. One of these is shown in Fig. 1, the other being directly behind it. The uprights are joined at the top as shown in Fig. 5 by a member 26 similar to cross bar 12. The idler 19 is pivoted to the member 26 while both the shafts 17 and 21 are similarly secured to the, rear upright 24 on opposite sides thereof and at such a distance apart that the mutilated gear 22 and pinion 23 will mesh properly.

As stated previously, the shaft 17 is rotated intermittently by means of the gear 22, and in order to prevent it from rotating after the mutilated gear has. ceased to act on it, due to its inertia and that of the connected parts, I usea catch shown in Figs. 5 and 10. This consists of a disk 27 fitted to the shaft 17, having a lug or shoulder 28 thereon. The lug 28 engages the dog 30 pivoted at 31 to a projection 33 of the leg 1. A spring 32 connected between the dog 30 and the cross piece 2 holds it against "the disk. The disk 27 is placed in a position such that the end 29 of the dog engages the lug 28 at the instant that the mutilated gear 22 lets go of the pinion 23. A trip '33 is secured on the shaft 21 to raise the dog 30 out of. engagement, just before the mutilated gear again meshes with the pinion.

The shaft 17 is supported at various points along its length by the brackets 31 which rest upon the cross-pieces 2, one being shown in Figs. 3 and 4:. A plate 35 having a notch 36 is attached to the end of the shaft 17. A pin 37 secured to the plate moves in a slot 38 in the reciprocating arm 39, which is pivoted at -l0 to a supporting member 41. This may be conveniently fastened to the leg 1 as shown. At the other end of the arm 39, a connecting rod -12 is attached by a double acting joint 13. A projection of the joint turns in the arm 39 and the connecting rod is pivoted between lugs on the joint so that it can swing either in the plane of the arm 39 or in a plane at right angles thereto. The other end of the connecting rod is fastened to the short link 15 by a pin ll which is parallel to the plane of the shaft 17. The link i5 is also pivoted at the other extremity to the arm 17 by a pin 16, at right angles to the pin ii. The feeding arm l7 rotates loosely about the axis l8 and has a dog adapted to engage the ratchet wheel l9 rigidly mounted on the axis l8. A suitable spring 51 is connected between the reciprocating arm 17 and the dog to keep it in engagement with the ratchet wheel A9. A pivoted arm or dog 52 operated by a spring 53 cooperates with a notch 36 of the plate 35 to prevent the shaft 17 from rebounding in the opposite direction as will be fully described later.

To the left of the driving mechanism in Fig. 1, there are successively arranged devices for, first: inserting a bottom disk; second, a cylindrical lining; and third two additional bottom disks. Theses devices will now be described in the order given.

The first is best shown in Figs. 1 and 6. Referring thereto, two standards 54: of an inverted Y shape are securely fastened to the support A and are provided with bearings 55 for the shaft 13. The eccentric 58 consists of a circular portion 56 which is eccentrically mounted upon the shaft 13 and may be adjusted thereon by manipulating screws 57. A frame surrounds the eccentric and is made up of two semi-circular portions 58 and 59 bolted together. The lower portion 59 has a projection 60 into which a connecting rod is fastened. The connecting rod ()1 is pivotally secured to a cross head 62 which moves between the guides 63 fastened to the standards 54. Attached to the head 02 is a plunger 64 which moves in a hollow guide way 65. The guide way is sup ported by a member 66 resting upon bar 67 and shelf 68 both being fastened across the standards. The shelf is also supported by braces 69 between it and the standards. The plunger 64 is reciprocated by the eccentric 58 on the shaft 13 and passes through the circular holes '70 in the member 66 and a corresponding hole 71 in the slide 71. A magazine 72 containing disks 73 and weight 73 is secured to the member 66. A circular opening 7% in the upper part of the member permits the bottom disk to rest on the slide. The slide 71 is fastened to the projecting lug 7 7 of the eccentric 78 by a connecting rod 75 pivoted at 76. This eccentric is constructed in the same manner as the eccentric 58 previously described. The eccentric 78 is rotated upon the intermittently rotat ing shaft 17. The stroke of the plunger 64: is sufficient to permit it to descend substantially to the bottom of the cans 10. During the period in which the shaft 17 is sta-. I

tionary, the single hole in the slide 71 is in alinement with the hole 70 below the plunger so as to permit it to pass therethrough. the openings in the can 10 underneath being likewise in alinement.

The mechanism for inserting the cylindrical lining is placed to the left of the first mechanism. Referring to Figs. 1 and 7, this device consists of a hollow cylindrical 'plunger 79 fastened to a frame 80. The

frame and plunger are reciprocated by means of two eccentrics 81 and 82 similar to the eccentric 58. The frame 80 and the eccentrics are connected by means of con-. necting rods 83. A flared guide or funnel 81 is slidingly suspended from the frame by rods 85 and is yieldingly retained against the nuts at the lower end by springs 87 surrounding the rods. The frame 80 joins two cross-heads 80, each of which moves between two guides 89 fastened to the upright members 90 as shown in Fig. 7.

The uprights 90 are connected across the top by beams 91 and at the bottom are fastened to the support 1. A shaft 92 is mount ed across the beams 91 and fits in bearings thereon. A sprocket wheel 93 is secured on this shaft and is rotated by chain 94: and "toothed wheel 95 on the intermittently rotating shaft 17. The bevel gear 96 on the shaft 92 meshes with the pinion 97 mounted on a vertical shaft 98. This shaft is supported by a bearing 99 fastened across the uprights 90. At the other extremity of the shaft 98 is fastened a cylinder 100 having a longitudinal slot 101 as shown in Fig. 8. A sheet metal drum or cylinder 102 having flaring ends 103 and 104 surrounds the cylinder 100, a space 105 being left between the two cylinders to receive the lining. An opening 107 is left between the ends 103 and 104 so that the lining 108 may be pushed into the slot .101 and then wound up in the intermediate space 105. The sheet metal cylinder 102 rests upon 'the table 106 supported by the members90, a hole 106 being provided for the guide 84 to pass therethrough. The manner in which the the mutilated gear.

hollow .cylindrical plunger 79 removes the lining and deposits it in the can will be described later.

After the lining is inserted by the plunger, two more disks are put in place by a mechanism placed still farther to the left. This arrangement consists of two devices identical with that described for inserting a single disk, with the exception that one slide 116 removes the disks from both devices. The plungers 109 and 110 are operated by the eccentric 111 identical with 58 and are fastened to the head 112 moving between guides 113 secured to the standards 114. A connecting rod 115 joins the eccentric to the head 112. The slide 116 reciprocates in the frame 117 supported on a table 118. This slide has two holes 116' and 116 side by side adapted to pass under the two magazines 120 and 120 (Fig. 13) and is operated by eccentric 121. The other details of this arrangement are identical with those of the disk insertingw mechanism first described.

, .A standard 122 at the left hand extremity as shown in Fig. 1 supports the end of the shaft 13. Projection 123 is attached to this standard to serve as a pivot for the catch 52; Another projection 12 1 on this standard serves as a fastening for the spring 53.

Fig. 2 shows a dry cell can with the elements which are inserted by this apparatus. In the zinc can 125 is placed a bottom disk 126, a lining" 127 and disks 128 and 129 in-' said? of the lining and on top of the bottom The intermittent operation of the shaft 17' is produced as follows: Referring to Figs. 1 and 5, the driving mechanism for the apparatus is operated b a belt 16 driven by any source ofpower. y this means a pulley 15 fastened to the shaft 13 is rotated continuously. In the section shown in Fig. 5, the direction of this rotation is indicated as being clockwise. Upon the shaft 13, the gear 18'and the 'four similar eccentrics 58, 81, 82 and 111 are rotated continuously. The gear 18 turns the idler 19 which meshes with an other gear 20 similar to gear 18. The gear 20 and shaft 21 are therefore rotated in the large as the pinion, hence, the pinion is rotated once during a complete revolution of The shaft 17 thus rotates counter clockwise. and makes the same number of revolutions inv a given period as the shafts 13 and 21, butrotates three times as fast. It remains stationary durin the othier two-thirds revolution of the sha s 13 an 21,

In order to prevent the shaft from rotatingafter the mutilatedgear has ceased to act on the pinion 23, Imake use of the arrangement shown in Figs. 5 and 10. At the in.- stant that the teeth of the mutilated gear cease to mesh with pinion 23, the catch 28 will engage the shoulder 29. This will prevent the inertia of the moving parts from rotating theshaft 17 any farther. The impact of the dog against the catch is liable to cause theshaft 17 to rebound and in order to prevent this, the dog 52 placed on the feeding-end of the shaft, as shown in Figs. 3 and 4, drops into notch 36 of the disk 37, at the same instantthat the catch 28 and shoulder 29 come into engagement and the shaft is thus prevented from rotating in either direction. Spring 53 maintains the dog 52 in engagement with the periphery of the disk 35; The mutilated gear 22 and shaft 21 will then continue their rotation main stationary. The catch 29 must, however, be lifted before the mutilated gear meshes again with the pinion. A trip 33 (Fig. 10) is therefore secured to the shaft 21 to lift the dog 29, just before the mutilated gear meshes with the pinion and to hold it long enough to permit the shoulder 28 to pass under the end of the dog. When the trip 33 rotates farther, it will release the dog and permit the spring 32 to return it to its original position.

During the rotation of the shaft 17 rotary motion is transmitted to the shaft 98 (Fig. 7) through the sprocket 95, chain 94, sprocket 93 and bevel gears 96 and 97. The shaft 98 is turned through two complete revolutions for each revolution of the shaft .17 for a purpose that will be described later. This chain and gear mechanism and the con-' nected parts insert the lining in the can as follows: The operator will place a lining 108 in the slot 101 where it will be in position to be coiled around the former 100 as soon as it commences to rotate. When it is coiled therearound, the plunger 79 descends through the action of the eccentrics 81 and 82 and forces it into the can underneath. In order to guide the lining properly, the funnel 84: is provided as previously described. Atv a predetermined point in the upward travel of plunger 79, the nuts on the rods, 85 raise the funnel 8 1 from engagement with the can 10,'and likewise at a predetermined point on the downward stroke of the plunger, the funnel is pushed downward into engagement therewith where it remains during further descent of the plunger. As the plunger descends, the rods 85 slide through the holes in the funnel and the springs 87 are compressed. In this way the funnel is retained above the cans during the period that they are moved along with con the disk inserting mechanism.

the end of the can beneath the lining mechanism just before the lining is pushed down into it. y I

The complete operation of the apparatus in inserting the disks and the lining is as follows: Referring to Fig. 1, the dry cell cans or containers 10 will be placed in the holders 9 at the right end of the apparatus by any means. For the purpose of explanation, it will be assumed that the cans are placed manually in the holders. The rotating shaft 13 will transmit motion through the train of gears and cause the intermittent movement of shaft 17 as has been previously explained. The shaft 17. through the arms and links at the left hand side of the apparatus of Fig. 1 (shown in detail in Fig. 1) will step the conveyer 8 along one notch at a time for each revolution. The distance moved is the same as the distance between the centers of the can holders 9. In this way the conveyer is stepped along until the first can placed therein is adjacent The next revolution of the shaft 13 causes one com 1 plete revolution of the shaft 17 through the mutilated gear arrangement and this rotation moves the conveyer so as to place the can directly under the member 65 (Fig. 6) where it remains stationary. During the time that the conveyer was moved through this distance, the eccentric 78 on the shaft 17 pushed the slide 71 to the right in Fig. 6 to receive a paper .disk '73 in the hole 71 and drew it back with this disk in alinement with the can 10 beneath. As shown in Figs. 4 and 6, the shaft 17 has turned through half a revolution, leaving one-half of a revolution yet to be completed before the mutilated gear ceases to mesh with the pinion 23 thereon. The ratio of the pitch of the gears 22 and 23 is such that the plunger 64' is entirely above the slide 71 while the shaft 17 is rotating. When the shaft ceases to rotate, the descending plunger pushes the paper disk from the slide 71 into the can 10 and then moves upward to clear the slide before the mutilated gear 22 again meshes with gear 23. The next engagement of these two gears causes the conveyer to he stepped forward again to place another can under the disk inserting mechanism where the same process is repeated. The first can is stepped along until it reaches the mechanism for inserting the lining, and during this period disks have been inserted in the succeeding cans as they ass under the disk inserting mechanism. ust before the can is moved up to the position under this mechanism, a lining 108 is shoved into the slot 101 of the former 100 in position to be coiled thereon. This lining can be placed in position by any means but it is assumed that it will be done manually by any attendant. When the mutilated gear meshes around it inside of the drum 105.

with the pinion on the, shaft 17 motion is transmitted to the former 100 through the chain and gears (Fig. 7) and it is turned around twice. During the revolution of the former, the lining is drawn in and wrapped The lining is of such a length that it will have overlapping ends when coiled on the former 100 but in order to have the slot 101 in correct position to receive another lining, it is turned through two revolutions though, of course, it could equally as well be designed to turn through any whole number of revolutions greater than one. During the time that the lining has been drawn in and wrapped around the former, the sleeve or plunger 79 has been entirely above it as is shown in Fig. 7. This plunger is forced downward by the eccentrics 81 and 82 (Fig. 1) and engages the coiled lining 108' after it ceases to rotate and pushes it down through the funnel 84 into the can 10 on top of the paper disk. Further, rotation of the shaft 13 then causes the plunger 79 to rise and clear the cylinder 100, and when the mutilated gear 22 again comes in engagement with the pinion 23, the conveyer 8 is stepped forward and the next can is placed under the lining mechanism. Just as soon as the plunger 79 clears the former 100 the operator will place another lining 108v in the slot 101 in readiness to be coiled about it when the shaft 17 is again rotated.

The can first described after having the lining placed therein is stepped forward repeatedly until it comes under the plunger 110, Fig. 1, in position to have a second disk inserted therein. The slide 116 (Figs. 1 and 13) is reciprocated back and forth by an eccentric on the shaft 17 exactly in the same manner as the slide 71 which placed the first disk in the can. When the shaft 17, therefore, is turned through one revolution, the paper disk drops into the hole 116 in the slide 117 and is drawn to a position over the can where it will be forced therein by the descending plunger 110. The can is then further stepped along until it comes under the plunger 109 in position to receive a third disk. This disk is placed in position to be forced into the can by the slide 116. The disk is brought into position over the can after having been fedinto the hole 116" from the magazine 120. .This isthe last operation that will be performed on the can traced along the container and it will be stepped along until it reaches the left hand end of the apparatus where it will either be removed by an attendant or drop into a hopper as it turns around the wheel 5.

In the way described, each can that is put in the container on the right hand side will pass successively first under the first disk inserting mechanisms to receive a disk; second, under the lining mechanism to receive a lining; third, under the second disk inserting, mechanism to receive a second disk; and fourth, under the third disk inserting mechanism to receive the third disk.

It is the usual practice to place one lining and three disks in each dry cell container but it will, of course, be obvious that my invention is not limited to this number.

The apparatus can be arranged to insert any number of disks or any number of linings and the example illustrated in the drawing is only intended to be illustrative of the manner in which the various operations can be erformed.
