The platform 91 is rectangular in outline and ismounted on the upper end of a vertical stem or shaft 98 which is telescopically carried within a-sleeve illl, slidable in a pedestal I02 secured to The platform 9'! is raised and lowered by a lifter lever I03 loosely mounted on a pivot shaft Hi4 secured in the frame 22 (Figs. 1, 3 and.5)*.. The lever intermediate its ends carries a cam roller ['05 which operates within a cam racewayriflfi of a barrel cam i0! mounted on the shaft 38. The inner end of lever I03 engages the platform shaft 98 in a ball and socket joint N18 for efiecting the movement of the platform 91 in time with other operations ofthemachine.

With the platform 9! raised-and the divider sheets Bin place a illustratedirrFig; 1; the'inie tial layer of assembled-cans A: on the assembly tracks now arelowered onto the platformv 91"...

This-is'eifected by spreading apart :or openingthe tracks 56,- 51' from their normally closed po-' sition for dropping the rows of, cans therebes tween (Fig. 8); The platform, 9? meanwhile: stands still to; receive the cans and the gates 25 remain in theirlowered position holding back thesupply of cans in the-runways.-

As the" initial layer of cans isdepositedon the platform the adjacent rows of cans are crowded" to opposite ends of the rows or; sides; of the assembly frame in order to arrange the cans in staggered relation. elements; H1 pivotally carried on pins H8 in 0 brackets [ZI secured to the bottom face of the an. extended arm: which is weighted at I23 atthe opposite end. Fingers I22 extend upwardly through openings l24'in the platform and-engage the cans at opposite ends of adjacent'rows andthus holds. these rows in place on the platform in a staggered relation.

The platform after receiving its initial layer of assembled cans is moved down to a plane, a distance substantially equal to the diameter of the can A preparatory to receiving asecond layer. The divider sheets B disposed between the ends of the cans move down with the platform. The assembly'tracks 56, 5'! meanwhile have moved together again into their closed position for receiving an additional supply ofcans from the runways. for assembling: them into a second layer.

The-operations of openingv the; assembly tracks 56, 51 thereafter are repeated and the second.

layer of cans are dropped down, this time onto the initial layer already disposed in staggered relation on the platform. The cansof this secand layer, guidedby the side plates M5,. l-IBof This is doneby retractable- 5. the frame II4, fall into position on the curved surfaces between adjacent cans of the initial layer and thus stagger the cans relative to the initial layer.

The operations of the gates 25 and the assembly tracks 56, are continued as hereinbefore described in time with the lowering of the platform 91 successively, in step-by-step relation until the platform is fully loaded with superimposed layers of cans. The platform at such a time reaches a position at the bottom of the assembly frame II4 where it dwells momentarily while the stack of cans as a unit is discharged there- ,from. Just before the platform reaches the bottom of the assembly frame, the fingers I22 of the retractable elements release their hold on the cans in the initial layer and are withdrawn from the openings I24. This is effected by the weighted ends I23 of the arms engaging against a stationary horizontal plate I26 secured to the frame 22.

The superimposed layers of cans are now free to be shifted endwise to bring all the cans in the adjacent rows together into a compact assembly and to thereafter continue the shifting thereof (to the right as viewed in Figs. 2 and 5) into an opened bag C disposed in position at an opened end of the assembly frame II4. Fig. 4 of the drawings illustrates a unit stack D of cans after being pushed together with the dividers B positioned between the rows. The rows of cans are disposed in a novel staggered relation laterally,

longitudinally and vertically and are thus interlocked in such a manner as to provide a firm compact stack ready for insertion as a unit in the opened bag C.

The bag C comprise a flexible container, shipping carrier or the like formed of flexible mate-' rial such as paper and when in an expanded condition forms a square or rectangular container having four side walls and a bottom. Such a container or bag is shown held in opened position on mandrel units I21 and corner rods I28 se cured to the machine frame (Figs. 2, 3 and 5). The big C is placed in position by hand.

Provision is made for shifting the stack D of cans as a unit, into the bag C, in a single stroke. This is done by means of a stack shifting device I3I mounted on a frame extension I32 of the machine frame (Figs. 2 and 5). Such a device operates a movable wall or pusher plate I33 which is carried at one end of the device and which is movable into and through the assembly frame 4 for effecting the shifting of the unit stack from the platform 91 into the bag C.

A device I3I (Fig. 5) includes an air cylinder I34 having a cylinder head I35 secured to one end and a telescopical sliding unit I36 operable Within the cylinder. Such a unit includes a piston I31 and an auxiliary or inner piston I38. Piston I3'I is formed on the inner end of the unit I36 and is slidable within the cylinder I34. Auxiliary piston I38 is formed on the inner end .of a piston rod I4I slidable within an auxiliary cylinder I42 of the unit I36. Piston rod MI is slid.- able in a bore I43 of the unit I36 and has its outer end secured to the movable plate I33.

Control of the stack shifting device I3I is effected through a valve I45 which is connected thereto by suitable pipe connections (Fig. 5)-- Valve I45 comprises a housing I46 having a bore I4'I within which a stem or plunger I48 is slidable. The housing I46 is provided with an inlet connection I5I which communicates with the bore I41 for supplying compressed air from any suitable source to this valve.

The opposite side of the housing I46 is provided with pipe fittings I52, I53 which communicate with the bore I4I. Pipe connection I 54 connects the fitting I52 with an inlet opening I55 in the cylinder head I35. Pipe connection I56 connects the fittings I53 with a telescopical pipe connection I51 secured to the cylinder I34. An inner pipe I58 is slidable in the telescopical pipe connection I51 and leads to an inlet opening I6I in the unit I36 wherein it is secured. A pipe connection I62 connects the fitting I53 with an inlet opening I63 in the cylinder I34.

The stem I48 (Fig. 5) is formed with a reduced section I64 intermediate its ends for providing an air passage I 65 surrounding it within the bore I41 so that the inlet pipe connection I5I may have communication with openings in the pipe fittings I52, I53 as the stem is moved within the bore I4'I. Stem I48 also is formed with outlet openings I66, I61 which have communication with openings in the pipe fittings and also with the outside atmosphere when the stem I48 moves into difierent positions.

The valve I45 is actuated by a solenoid I'II in proper time with other operations of the machine for controlling the movement of the stem I48 and thus effecting the operation of the stack shifting device I3I. The stem I48 normally is held in an inoperative position by a spring I12 which is retained in place by a wall extension I13 secured to the housing I46.

The solenoid I'II is energized through a normally open switch I14 which is mounted on the frame 22. Provision is made to operate this switch by a cam segment I'I5 on the cam I97 which closes the switch at the desired time (Fig. 1).

The switch H4 is connected by a wire I76 to a source of electric current, such as a generator I'II (Fig. 5) which in turn is connected by a wire II8 to one side of the solenoid I'M. A wire I8I connects the other side of the solenoid with the switch.

Hence, as the solenoid is energized through closing of the switch I14, the stem I48 is shifted within the bore I4! and closes the air supply to the opening in the pipe fitting I53 and brings the outlet opening I67 into communication with it for bleeding air in the device I3I to the atmosphere. This action also uncovers theopening in the pipe fitting I52 to a supply of air from the pipe connection I5I. A supply of compressed air then passes through'the valve I45, pipe fitting I52, pipe connection I54, inlet opening I55 into the air cylinder I34 thus forcing both the pistons I31, I38 to move toward the right (Fig. 5).

Piston I3'I reaches the end of its stroke when it engages against a wall I of the air cylinder I34 whereupon the piston I38 continues to move within the unit I35 until it reaches the end of its stroke engaging against a wall I86 at the end of the unit. During this stroke of the shifting device I3I the unit stack of cans is shifted by the plate I33 and deposited into the bag C at the opposite side of the machine.

At the end of this shifting stroke of the shifting device I3I, the switch I14 is opened and the solenoid I'II is deenergized. The spring H2 thereupon moves the stem I48 to the right as viewed in Fig. 5 and closes off the supply of air to the fitting I52 and uncovers it to the outlet opening I66 for bleeding the air in the device v I3I to the outside atmosphere. This action also uncovers the opening in the pipe fitting I53 to a supply of compressed air and allows it to pass into pipe connections I56, I52, telescopical pipe connections I51, I58 and inlet openings IEI, I63 into the outer and inner cylinders I34, I42 for moving the pistons I31, I38 toward the left (as viewed in Fig. Hence, the parts of the device I3I and the movable plate I33 are returned to their normal position (Fig. 5) where they remain until the next unit stack of cans is ready for shifting as hereinbefore explained.

The operations of the machine thereafter are repeated as the platform 91 moves upwardly again to receive a subsequent or initial layer of cans which are fed in, assembled and discharged upon the platform as previously described.

The filled bag 0 meanwhile is withdrawn manually or in any other suitable manner, from the mandrel units I2! and the corner rods I28 for discharge from the machine, whereupon another bag 0 is slipped in position on they units and the rods for receiving the next unit stack of cans.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
