continuously. The main drive shaft, however, is
normally stationary and is rotated periodically
corresponding relation.
The rows of cans, as they are segregated are
lifted vertically and arranged in position to form
a compact, orderly mass or layer unit.
When
the unit is complete the entire mass is pushed
horizontally into a mould D or package holding
device which is surrounded by a paper bag or
can package B. As each layer unit is deposited
in the mould a ?bre separator sheet E is inserted
into place in front of the layer of cans. In this
manner a plurality of layers of cans separated by
?bre sheets E are built up in the mould until it
is ?lled. When the mould D is ?lled the bag B
with its load of cans is removed and sealed ready
for shipment or storage.
The cans A advance into the machine in a
by a suitable commercial one-revolution clutch
51 (Figs. 6 and 11) having a driving member 58
keyed to the drive shaft and a driven member 59
secured to the drive sprocket 52. The clutch is
actuated by a pivotally mounted clutch ?nger
6| controlled by a movable element 62 Of an elec
tric solenoid 63 carried on the transverse web 45
10 of the main frame 22.
Hence when a full row of cans A is assembled
on the table 23 as shown in Fig. 11, they create
a pressure against the stop arm 25 sufficient to
pivot the arm on its pin 21 against the resistance
of its wire spring 36. This movement of the arm
brings its switch contact against the switch con
tact of the stop lever 28 and this closes the switch
35. Closing of the switch energizes the main
clutch solenoid 63 (Fig. 6) and this actuates the
end of which is secured to a vertical frame 22 20 clutch ?nger 6| to throw in the clutch 51. The
vmain drive shaft 49 thereupon begins its move
having an H shaped horizontal cross section
continuous procession moving along an inclined
runway 2| (Figs. 1, 6, '7, 8 and 11), the machine
which constitutes the main frame of the machine.
In the machine the cans roll along a horizontal
table or support 23 (Figs. 9 and 11) which is
formed as an integral part of the main frame 22.
ment and rotates through one revolution after
which it stops.
During the rotation of the main drive shaft
49 the cans A on the table are lifted vertically
and the jack shaft 43 and the cam 42 carried
thereon rotate through one-half revolution. This
shifts the stop lever 28 inwardly, as hereinabove
explained, to locate the next row of incoming
one row, as hereinbefore mentioned. The num

This table is substantially as wide or deep as the
height of the cans received thereon.
The number of cans on the table 23‘ constitute
table is controlled by a stop} arm or element 25
which is disposed adjacent the terminal end of
the table, at the right as shown in Fig. 11. Where
the cans are to be stacked in a stagger layout as
shown in the drawings, the stop arm 25 recipro
cates along the table a .distance of one-half the
diameter of a can and in shifted position stops
alternate rows of cans one-half a diameter ahead
' of the inbetween rows.
It is this locating of the
to the row just elevated. As soon as the row of
cans being elevated has passed above the stop
arm 25 and released the same, the spring 36 opens
the switch 35 and this deenergizes the solenoid
63 to permit stopping of the main drive shaft at
the end of its one revolution. This cycle is re
peated for each row of cans to be elevated into
stacked formation.
Lifting of the rows of cans is effected by a
cans that forms the staggered or nesting relation 40 plurality of spaced and parallel, vertically dis
posed magnetic feed or lift bars 66 (Figs. 6, '7, 8,
9 and 10) which are located adjacent the front

secured in a pair of lugs 3| formed on the inner 45 plate 68 which extends transversely across the
front of the machine and at its ends is bolted

The stop arm 25 is mounted loosely on a pivot

a switch 35 which is used, as will be hereinafter
’ explained in connection with the wiring diagram

top edge of the transverse web 45 of the main

a movable element I I5 of a normally deenergized
electric solenoid II6 mounted on the transverse
web 45 of the main frame 22.
Energization of the clutch solenoid I I6 is
brought about by an electric switch II'I (Fig.
18) which is opened and closed at the proper
time by an edge cam II8. The cam is mounted
cans elevated.
Hence when a full layer unit of cans has been
stacked in position in front of the mould D,
by the combined action of the lift bars 60 and
the holding plates BI, the gear I23 has been ro
tated sui?ciently to move the cam II8 which in ,
turn closes the switch Ill. The energizes the
clutch solenoid I I6 and thus throws in the clutch
III. This operation of the clutch rotates the
short shaft I03 through one revolution before
adjacent one face of the cans. This sheet serves
as a spacer or separator element to keep the
layers of cans separated to avoid damage to the
cans and prevent their shifting out of place
while in the bag.
