Figure 17 is a side elevation of Figure 16.

Referring more particularly .to the drawings the numerals 20 and 21 designate-the side walls of a supporting structure, 22 the back and 23 the front wall, which latter is arranged adjacent the bottom of the structure and supported by the frame thusformed is an annular delivery frame or member 24, over which a carton 25 is sleeved, and into which carton superposed or stacks of containers are delivered at predetermined times in the cycle of operation of the machine. The carton 25 is removed by the placing of containers thereinto.

Supported by the side walls to extend across the frame is a shaft 26 rotatable in suitable bearings, and carried by the shaft 26 to rotate therewith are sprocket wheels 27, the wheels being located within the frame and adjacent the respective side walls 20 and 21.

Extending across the frame andjournaled in suitable bearings in the side walls, adjacent the bottom of the frame, is another shaft 28 which supports sprocket wheels 29, one beneath each of the respective wheels 2'7 on the shaft 26.

Endless sprocket chains 30 pass over the respective pairs of sprockets 2729 and carried by the sprocket chains at suitable intervals are a plurality of members 31.

Platforms 32 are secured by their extremities in any suitable manner to these members, preferably by deflecting the extremities of the platforms so that the platforms will extend across the space between the sprocket chains 30.

Guides 33 are preferably arranged adjacent the inlet of the delivery frame or member 24 and between which guides the members 31 pass when the respective platforms 32 are moving in a verticalplane adjacent the inlet of the delivery frame or member 24, so as to hold the platforms and the sprocketchains 30 against being deflected laterally when the cartons are delivered upon the platform and also when the superposed stacks are ejected therefrom.

Motion is intermittently imparted to the plati connected at its ends to members 37 slidable in' guides 38 (see particularly Figures 1 and 4) adjacent the outer faces of the walls 2021.

The receiver extends across the frame and the ends thereof pass through suitable slots 39 in the side walls andare connected with the mem-' bers 37.

The receiver is reciprocated by means of yoke like members 40 pivotally mounted adjacent their lower ends by means of a shaft 41.

Arms 42 are connected with the members 37 and also with the ends of the yokes 40, preferably through the medium of pins 43 engaging in slots 44 in the arms 42, to permit of a rocking motion being imparted to the yoke 40 and a sliding movement to the member 37.

The yokes are adapted to be rocked by means of eccentrics 45 which rotate in bearing blocks 46 slidable in the yokes 40.

When the eccentrics 45 are rotated a reciprocating movement will be imparted to the blocks or bearings 46 to cause them to slide in the yokes and this reciprocating movement will cause the yokes 40 to be rocked about their pivots 41 and thereby impart a forward and backwardly sliding movement to the receiver 36.

The receiver 36 is adapted to assume a position at the end of the chute or runway 35 and as the containers 4'7 (see particularly Figures 4 and-5) are delivered thereupon, thecontainers will pass beneath a stationary member or ledge 48.

When a predetermined number of the containers have been delivered to the receiver 36, the latter is moved forwardly to a position directly above and in close proximity to the path of movement of-the platforms 32 carried by the sprocket chains 30.

As the receiver moves forwardly with the containers 4'7 thereon the containers will pass beneath a stripper 49 which is pivotally mounted or connected with the plate 48 as at 50 (see Figure '7). When the receiver 36 has reached the limit of. its forward movement with the containers thereon, the forward edge of the stripper 49 will pass off of the containers and fall behind the rear end thereof.

As the receiver is then moved rearwardly and into a position to receive another supply of containers from the chute or runway 35, it will be stripped of the containers which have been advanced thereby, by reason of the fact that the stripper 49 will prevent the return of the containers with the receiver.

The containers stripped from the receiver 36 will be delivered to the adjacent platform 32 and at a predetermined time in the cycle of operation of the machine, the sprockets 27--29 will be given one step of rotation to lower the platform 32 to a position that the next supply of containers to be delivered from the receiver 36 will be superposed upon the previously delivered containers on the platform 32. This operation continues until the desired number of containers have been superposed upon the platform.

feedingwheels or discs 51 which are adapted to engage and rest upon the tops of the containers, and these discs may be rotated in any suitable manner through the medium of a worm 52 engaging a worm gear 53 on the shaft of the disc 51.

The discs and the driving mechanism therefor are supported by means of a casing 54 having a shaft 55 therein driven by means of a shaft 56 to which the shaft 55 (see particularly Figures 4 and 7) is connected, through the medium of a universal coupling 47. The casing 54 is. pivotally mounted as at 58 in direct alinement with the joint of the universal coupling 57, so that the casing 54 may rise and fall to a limited extent without interfering with the operation of the discs 51. The shaft 56 is rotated in a manner that will be hereinafter described.

After a predetermined number of containers 47 have been superposed upon the platform 32 (see particularly Figure 5) the platform 32 will have reached a position adjacent the bottom of the delivery frame or member 24, and during an interval of rest of the sprocket wheels 2'l29 and the platforms 32, the superposed containers will be ejected from the platform 32 into the delivery frame or member 24. The platform 32 will again be intermittently advanced until another platform with the superposed containers thereon reaches a position adjacent the bottom of the delivery frame or member 24, and the containers thereon will be likewise ejected from their respective platform.

This operation will continue and the superposed containers will be intermittently advanced through the delivery frame or member 24 until the outermost tier or stack engages the bottom ofthe carton 25. A continued delivery of the superposed containers into the delivery frame 24 will cause the carton 25 to be stripped from the frame with the containers therein.

In order to accomplish this operation there is provided an ejector 58 which is adapted to be reciprocated by means of the yokes 40.

To that end there is provided a reciprocable member 59 the ends of which member project through slots 60 in the side members 2021 of the frame and move between guide ways 61 on the outer faces of the' members 2021 (see particularly Figures 1 and 4).

Each end of the member 59 (see particularly Figures 2 and 3) is provided with a lug 62 projecting laterally therefrom, and pivotally connected with each of the yokes 40 as at 63 (see also Figure 1) is an arm 64. These arms carry members 65 having a bifurcated lower extremity 66 adapted to receive the respective lugs or projections 62, when the bifurcation is in a position to permit the lug to pass therein.

When the arms 64 are lowered so as to causethe bifurcation to engage over the lugs 62, the member 59 will be moved forwardly upon a corresponding movement of the yokes 40 and will be returned by the yokes.

The ejector 58, however, is not operated upon every step of operation of the receiver 36, but is only operated at predetermined intervals with respect to the operation of the receiver.

That is to say, in the present form of the invention, the platforms together with the sprocket wheels 27-29 and the sprocket-chains 30 are adapted to be given four steps of advancing movement, so that four layers of containers will be superposed upon the ,platform 32, before the entire stack or tier is ejected from the platform into the delivery frame or member24 by the ejector 58, as the ejector operates only after every fourth step of advancing movement of the platforms.

This is accomplished by reason of the fact that during the oscillating movement which is imparted to the yokes 40 to reciprocate the receiver 36, as well as the ejector 58, the latter will be disconnected from the yoke during three steps of the advancing movement of the platforms 32, but will be automatically connected with the yokes upon the fourth step of advancing movement of the platform and the ejector will then eject the superposed containers from one platform and the receiver 36 will at the same time position one layer of containers to be delivered to the next successive platform.

The yokes 40 are connected to the ejector by allowing the arms 64 to drop, so that the bifurcation in the members will be in position to receive the lugs or projections 62 on the members 59, and the yokes will be disconnected from the member 59 by raising the arms 64-.

This is accomplished in the following manner: The members 65 are provided with anti-friction rollers 67 which are adapted to move on tracks 68 (see particularly Figures 1, 2, and 3).

The tracks 68 are supported by pivotally mounted arms 69, one pair of arms on opposite sides of the frame being connected by a rock shaft '70, the other pair of arms being pivoted to the frame by pivots '70. Springs '71 are connected with the respective tracks 68, preferably to deflected ends '72 of the tracks and these springs tend normally to elevate the tracks so as to raise the arms 64 to cause their bifurcation to disengage the respective lugs or projections 62.

When the tracks are in an elevated position .as shown in Figure 2, the yokes 40 may be operatedv to reciprocate the receiver 36, but the ejector 58 will remain inactive by reason of the fact that the yokes 40 are at that time disconnected therefrom.

When the tracks 68 are lowered against thestress of the springs '71, the arms 64 will drop so that the bifurcation 66 will engage over the lugs 62 on the members 59 and thereby connect the member 59 with the yokes 40 for reciprocation therewith.

Upon the completion of one complete cycle of operation of the ejector 58,'it will be disconnected from the yokes 40 by reason of the fact that the arms 64 will be elevated, and'the yokes 40 will then oscillate without imparting any motion to the ejector 58.

The tracks are elevated by the springs '71 and are lowered by means of an arm '73 (see particularly Figures 3 and 8) which is connected with the shaft '70 and extends rearwardly so that the extremity '74 of the arm will stand within the path of the upward movement of the members-31 on the sprocket chains 30, and the tracks will be held in their elevated position, or in the position shown in Figure 2, by the springs '71. The tracks will be lowered and held in their lowered position or in the position shown in Figure 3, by the member 31 engaging the extremity '74 of and rocking the arm '73, until the member 31 passes out of engagement with the arm '73. At this time the springs '71 will act upon the tracks 68 and cause them to be elevated to the position shown in Figure 2.

A stop '75 may be provided for limiting the movement of the arm '73 in the opposite direction.

The platforms 32 are given intermittent steps of advancement by intermittently rotating the shaft 26 and this is accomplished preferably in the following manner:

Carried by the shaft 26 and on the outside of the casing (see particularly Figures 3 and 4) is a disc like member '76 which is secured to the shaft for rotation therewith, and carried by the member '76 are a plurality of stops '7'! which project beyond the periphery of the disc and are adjustable circumferentially thereof so that they may be secured to the disc at any desired interval with respect to each other, preferably through the medium of fastening screws or bolts '78.

' A clutch member '79 is loosely mounted upon the shaft 26 and interposed between the adjacent faces of the clutch member and the disc '76 is a friction creating element 80.

A spring 81 is provided which encompasses a portion of the shaft 26, so that one end of the spring will rest against a ball bearing 82 that has contact with one face of the clutch member '79. The other end of the spring has contact with a member 83, which is adjustably mounted with respect to the shaft 26, through the medium of an adjusting device 84, so that the stress of the spring 81 may be varied.

The spring 81 tends normally to hold the clutch member '79 and the disc '76 frictionally locked under normal conditions, so that when the clutch member '79 is rotated through the medium of a sprocket wheel 85 carried thereby, the disc '76 and consequently the, shaft 26 will be rotated. The intermittent steps of rotation are imparted to the shaft 26 by arresting, at predetermined intervals in the operation of the machine, the rotation of the disc '76 and shaft 26, while the clutch member '79 is rotating. This will cause the clutch member '79 to slide with respect to the disc '76.

For the purpose of arresting the rotation of the disc '76 there is provided a stop 86 (see particularly Figures 2, 3, and 11). This stop device is preferably in-the form of a bell crank lever pivotally mounted as at 8'7. The extremity 88 of one arm of the lever is adapted to be moved into the path of movement of the'stops '77, so that when one of the stops '77 contacts with the extremity 88 of the arm 86, the-disc '76 will be held against rotation, but when the extremity 88 of the arm 86 is moved out of the path of movement of the advancing stop '77, the disc '76 and consequently the shaft 26 will be frictionally locked with the clutch member '79 and the sprocket wheel 85, to be rotated thereby.

The lever 86 is swung aboutits pivot in one direction by means of a spring 89 and in the other direction by means of a link 90 which latter is connected by one end to the other arm or the bell'crank lever, and is of a length to terminate in proximity to the shaft 28, at which point it is connected with another arm 91, intermediate the ends of the latter as at 92 and which arm 91 is pivotally mounted as at 93. A shoulder 94 is carried by the free end of the arm 91 and co-opcrates with a cam disc 95 loosely mounted upon the shaft 28, so that when the cam disc 95 is rotated and the high portion of the cam engages the projection 94 on the arm 91, the arm will be rocked about its pivot 93 and through the medium I of the link 90, will rock the bell crank lever 86 The cam 95 is adapted to be locked with the shaft 28 for rotation therewith by means of a dog or pawl 96, which is carried by the disc and H is'controlled by a spring 97;

Secured to the shaft 28 for rotation therewith is a toothed or ratchet wheel 98 with which the pawl 96 co-operates. When the pawl is in the position shown in Figure 3, the cam 95 will be looks the cam 95 with the shaft 28, the eccentric 45 will also be [rotated and there will be imparted an oscillating movement to the yokes 40.

Upon the completion of one complete cycle of rotation of the cam 95, which rotation will have imparted a forward and backward movement to the yoke 40, the pawl 96 will be operated to release the cam 95, and thereby arrest the movement of the yoke 40, at which time the bell crank lever will be in a position to be engaged by the next advancing projection on the disc 76. The mechanism which releases the pawl 96 is responsive in its operation to the feeding movement of the containers 47 on to the receiver 36 (see particularly Figures 4 and 11).

To that end there is provided a stop or abutment 99 which is arranged to be engaged by the foremost container 47 when they are in position upon the receiver 36.

As the containers roll down the chute 35 to the receiver, the front container will engage the abutment 99 and the stress of the containers thereagainst, which is augmented by the feeding movement imparted to the containers upon the receiver 36 by the feeding discs 51, the abutment 99 will be shifted and will, through the medium of an arm 100, which is connected thereto and which slides in a suitable bearing, rock a shaft 101 mounted in suitable bearings and which shaft is connected by means of a crank arm 102 with the arm 100 of the abutment 99.

Connected with the shaft 101 is another arm 103 which is provided with a cam shaped portion 104.

An arm or member 105 is pivotally supported at one end as at 106 and carries at its other end a pivoted latch 107 having a shoulder 108, and this latch is adapted to be engaged and moved about its pivot by the cam 104 carried by the arm 103.

The arm 105 is moved in one direction about its pivot preferably by means of a spring 109 (see Figure 3) which engages a fixed stop 110, and also an arm 111 which is connected with the member 105 by means of a pivot 112.

The arm 105 is positively moved in the opposite direction by means of a cam device 113 which engages a roller 114 carried by the arm 105, the cam 113 (see Figures 3 and 15) being rotated in a manner to be presently set forth.

A shoulder 108 on the arm 107 co-operates with a stop 115 on another arm 116 which latter is preferably pivotally mounted upon the pivot 106 to move the arm in one direction, and another shoulder 117 is provided on the arm 116 adapted to be positioned within the path of movement of one extremity of the pawl 96 to rock the latter and cause it to disengage-the toothed or ratchet wheel 98, thus releasing the cam '95 with respect to the shaft 28 and also the eccentric 45, thereby causing the yokes 40 to remain idle at the same, time that the pawl 96 is tripped by the shoulder 117, and the low portion of the cam 95 will have assumed a position with respect to the shoulder 94 on the arm 91, that the spring 89 will swing the bell crank lever 86 about its pivot to cause the extremity 88 thereof to move into the path of movement of the next advancing stop 77 on the disc 76.

This operation will take place at the time that the receiver 36 is being shifted and also at the time when the ejector 58 is being operated.

The arm 107 preferably passes through a guideway 118 on the arm 116, and a shoulder 119 may be provided on the arm 107 to limit the movement of the arm in one direction.

The arm 116 is moved in the opposite direction by means of a spring 120, so as to position the shoulder 117 in the path of movement of the pawl 96. The abutment 99 and the arm 103 with the cam 104 thereon is moved in the opposite direction by means of a spring 121.

It will therefore be seen that when the cam 104 (see particularly Figure .11) is moved so as to raise the arm 107, the shoulder 108 will be moved out of engagement with the shoulder 115 on the arm 116, and the latter will move forwardly under the stress of the spring 120, to position the shoulder 117 to be engaged by the pawl 96, and at that time the spring 109 (see also Figure 3) will, through the medium of the arm ,11, swing the arm 105 about its pivot. to cause the roller to be maintained in contact with the cam 113.

When the abutment 99 is shifted by the containers, the cam 104 will be moved out of engagement with the arm 107 and the latter will drop so that the shoulder 108 thereon will assume a position to engage the shoulder 115.

With the parts in this position, and when the cam 113 is rotated to swing the arm 105 against the stress of the spring 109, the arm 107 will, through the medium of the interengaging shoulders 108, 115 swing the arm 116 to move the shoulder 117 away from the pawl 96 to release the latter.

The cam 113, the clutch member 79 on the shaft 26 and sprocket 123 are rotated by means of an endless belt or slfrocket chain 122 (see par-. ticularly Figures 2, and 12) which passes over a sprocket wheel connected with the clutch member 79, which latter is rotatable upon the shaft 26, and also over the sprocket wheel 123. The sprocket chain also passes over a sprocket wheel 124 which is connected with the cam 113 (see also Figures 14 and 15) to rotate the latter.

The sprocket chain also passes over a sprocket wheel 125 (see also Figure 4) which is mounted loosely upon the shaft 56. The sprocket wheel 125 is connected with a clutch member 126,.and secured to the shaft 56 adjacent this clutch member is a ratchet wheel 127. Interposed between the clutch member 126 and the ratchet wheel 127, is a friction creating element 128,

ber of the containers is placed upon the receiver 36. At that time the sprocket wheel 125 will be disconnected with respect to the shaft 56, by rendering the clutch mechanism inactive. This will cause the feeding discs 51 to be rendered inactive and they will then serve as a means for arresting the supply of containers delivered from the chute or runway 35. At the time that the feeding discs 51 are rendered inactive they will be in a position to rest upon the top of one of the containers as shown in Figure 4.

The clutch thus formed is rendered inactive by arresting the movement of the ratchet wheel 1 27, and for that purpose there is provided a pawl 131, (see particularly Figures 2 and 7) whichengages the teeth of the ratchet wheel and holds the latter against rotation, allowing the clutch member 126 to slip with respect to the ratchet wheel.

The pawl is adapted to be rocked about its pivot 132 by means of an arm 133 arranged within the path of movement of the upper end of the yoke 40. A spring 134 is provided which tends normally to move the pawl 131 into engagement with the ratchet wheel 127, and when in this position the pawl will hold the ratchet wheel 127 against rotation, but the sprocket wheel 125 and the clutch member 126 will be rotated with respect to the shaft 56, by the chains 122.

Ifit is desired to place separators such as sheets of cardboard or the like intermediate predetermined stacks or piles of the containers as they are being placed into the carton or boxes,

means may be provided for feeding and placing such sheets therebetween at the proper time in the cycle of operation of the machine.

To that end a holder 135- (see particularly Figures 1, 2,5, 6 and 7,) is provided for holding division sheets 136 on end, and the holder is preferably inclined so as to facilitate in the feeding of the sheets to the delivery mechanism.

At the delivery end of the holder is a reciprocable bar or member 137 having pins or impalement devices 138 connected therewith for impaling the sheets and removing them separately from the supply.

This member 137 preferably reciprocates upon guides 139, through the medium of links 140 one end of each of which is connected with the member 137 and the other ends are pivotally connected as at 141 to discs 142. The discs are connected to operate in unison by means of a shaft 144, and one of the discs is preferably in the form of a sprocket wheel over which a sprocket chain 143 passes.

The sprocket chain 143 also passes over another sprocket wheel 145 wh ch carries a pawl 146. This pawl co-operates with a ratchet wheel 147 which is rotatable with respect to the sprocket 145, and rotatable with the ratchet wheel 147 is a gear wheel 148, with which a rack 149 engages (see particularly Figures 10, and 2 and 3) and the rack is connected with the member 59 and the ejector 58 for movement therewith, so that upon predetermined forward movement of the ejector 58 to eject a supply of containers from ihe platform 32, the member 137 carrying the pins 138 will be reciprocated lay-reason of the fact that the rack 149 w'll rotate the gear 148 which meshes therewith and the gear in turn rotates the sprocket wheel 145 and through the medium of the sprocket chain 143 the sprocket gear 142 will be rotated to rotate the discs 142 which latter are connected with the member 137 by means of the links 140. Upon each lowering movement of the member 137 one sheet or division member 136 will be removed from the holder 135. When the ejector 58 is moved in the opposite direction the member 137 will be raised by means of the rack 149 and gear 148, moving in the opposite direction, so that upon the next lowering operation, another sheet will be delivered.

As these sheets or division members are removed from the holder 135, the upper edges thereof will be passed, by the member 137, between co-operating feeding rollers 147, 148' and will be guded thereby into guideways, 149, so that when the partition members or sheets are released, they will drop in a vertical position from between the guideways 149 through guideways 150 and across the entrance end of the delivery frame or member 24and in advance of one of the tiers or stacks of containers 47 which are to be delivered upon the next movement of the ejector 58, from the adjacent platform 32.

Obviously the rate of speed or the intervals at which these division 'members or sheets may be supplied may be varied by interchanging the gear 148 with another gear, as will beunderstood.

Motion is imparted to the feed andguide rollers 147-148' preferably by means of a; sprocket chain 151, (see particularly Figure 2) .HWhich passes over a sprocket wheel 152 on the shaft 153, and which shaft carries the feed rolls 147. The sprocket chain also passes over a sprocket wheel 154 (see also Figures 14 and 15) which,is'

connected with the cam device 113' for rotation therewith.

Another sprocket wheel 155 is connected with the shaft 156 which carries the feed rolls 148' and this sprocket wheel may beheld in engagement with one of the runs of the endless chain 151, by means of 'a suitable spring controlled bearing member 157.

The guideways 149-150 are supported in suitable positions by means of supporting members In order to adapt this machine for feeding packages other than round containers 47, a shaft 159 (see particularly Figures 16 and 17) is employed in lieu of the shaft 56 and on this shaft is arranged the friction drive and ratchet mechanismsimilar to that shown in Figure 4 on the shaft 56.

This shaft 159 extends across the machine and has connected with it a worm 160 which meshes with a worm gear 161 that is carried by a shaft 162. This shaft is journaled in'suitable bearings 163 that are mounted for adjustment toward and away from each other as at 164. Journaled. in the bearings 163 are shafts which respectively carry feed rollers 165. Arranged opposite and spaced from each other and connectedwith the rollers 165 are worms 166 which mesh with worm gears 167 carried by the shaft 162. The bearings 16!; together with the respective worm gears 167 .are adjustable longitudinally of the shaft 162 toward and away. from each other and during this adjustment the feed rollers'165 are also moved respective worm gearing 166-167 is effected by adjusting the bearings 163 with respect to each other.

Thus it will be seen that the feed rollers 165 may be adjusted with respect to each other and during such adjustment the worm gears 167 will be adjusted longitudinally of the shaft 162, the worm gears being secured to the shaft 162 for rotation therewith and for adjustment longitudinally with respect thereto.

It is thought that the operation of this machine will be clearly understood from the foregoing description but briefly stated it is as follows:

Power is applied to the pulley 34 which is continuously operated and the shafts 26, 28 and 55 are connected with the pulley through the medium of the respective clutch devices. This will cause the sprocket chains 30 carrying the platforms 32 to be advanced, and intermittent advancing movements of the platforms 32 are pro duced by swinging the bell crank lever 86 so that its end will be moved into the path of the advancing movement of one of the projections 77 on the member 76. This will arrest the advancement of the projections 77 on the member 76, and the advancement of the platforms will be arrested.

When the bell crank lever 86 is swung out of the path of movement of the stops 77, another step of advancing movement will be imparted to the platforms.

The rocking of the lever 86 is effected through the medium of the feeding operation of the containers 47 from the chute 35 on to the receiver 36, and augmented by the feeding rollers 51 (see Figure 4).

The containers 47 will move the abutment 99 (see also Figure 11) to rock the shaft 101, and thereby swing the cam 104 to a position that the arm 107 will drop to position the shoulder 108 thereon so that it will engage the shoulder 115 on the arm 116.

As the cam 113 (see also Figure 3) rotates, it will, through the medium of the roller 114, rock the arm 105, and this rocking movement, will, through the medium of the arm 107 and shoulders 108, 115, rock the arm 116 to move the shoulder 11? out of contact with the pawl. When the pawl is thus released the spring 97 will cause the pawl to engage the toothed or ratchet wheel 98, thereby locking the cam 95 for rotation with the shaft 38.

As the cam 95 rotates it will raise the arm 91 and this raising movement of the arm, will. through the medium of the link 90, rock the bell crank lever 86 against the' stress of the spring 89 to permit the platforms to be advanced, the cam 95 making practically one complete revolution before shifting the arm 91.

As the low portion of the cam 95 approaches the arm 91, the spring 89 will cause the arm to follow the cam and this will move the end of the bell crank lever 86 into the path of the advance movement of one of the projections '77 on the disc 76 to arrest the advancing movement of the platforms.

Upon the completion of the third step of advance movement of the platforms. or any predetermined number of steps, according to the relative arrangement of the stops 77 on the disc 76, the ejector '58 will be operated to eject the superposed containers which are on the platform 32 adjacent the inlet of the delivery frame or member 24, during the time that another layer of containers are being moved by the receiver 36 into a position above the next adjacent platform 32, to be stripped from the receiver, and to this last mentioned platform, at the same time that the ejector 58 is being retracted.

The operation of rendering active and inactive the ejector- 58, is controlled by the tracks 68 which are raised by means of the springs 71 to render the ejector inactive, and are lowered by means of the arm 73 being shifted by the members 31 on the sprocket chains 30, to render the ejector active.

This shifting of the arm 73 will lower the tracks 68 to permit the arms 64 to rock about their pivots 63, so that the bifurcation in the members 65 will pass over the respective projections 62 on the member 59 to which the ejector isconnected, and thereby connect the ejector with the yokes 40, so that upon the next operation 01' the yokes the ejectors will be operated.

As the ejector 58 is actuated, the feeding mechanism for delivering sheets or partition members between respective stacks or tiers of the containers will also be actuated.

Obviously the feeding mechanism for the sheets 136 may be disconnected from the machine when it is not desired to insert these partition or division sheets.
