fixed arm 39 while intermediate its ends it is
the actuating members 58 and 58’ by the move
ment of post 82 which is connected to the yoke
8G through leaf springs 83.
This post 80 may be moved downwardly by any
provided with an arm 48 iixed to this shaft 38
and located in a slot 4| in the member 28. This 40 suitable means, such for instance as by a foot
arm 40 is slotted as at 42 and a link 43 con

' 46 attached as at 41 (Fig. 2) to the member 34
and by means of the hook 48 (see also Fig. 8)
to the member 28 serves to swing the member
34 about its pivot 32 until its block portion 35
engages the member 28 as shown in Fig. 8.
An actuating member designated generally 58
(see Figs. 8 and l1) and comprising a pulley
5I, rotatably mounted on the shaft 25 and having
an abutment 52 with an added friction wheel 53
mounted therein for engagement with the arm
39, is carried by this pulley 5|. A flexible mem
ber, such as chain 54, is wrapped about the drum
45
gized. Energy may be supplied to this solenoid
by the line 85 and 85 (see Fig. 3), the latter of
which has a mercury switch 81 in the line so that
when the post 82 nears the bottom of its stroke
the yoke 80 will swing the switch 81 downwardly
by means of its being mounted on the tiltable
platform 88, hinged as at 89 and returned to hori
zontal by spring 30, so as to break the circuit and
permit the post to again raise to starting position
through the action of the springs 68 and 60'
which will pull the yoke upwardly. A suitable
switch 9| may be located convenient to the oper
ator so that it may be closed until the post 82
has reached the bottom of its stroke when the
line will be automatically opened at the mercury
switch 81 and the operator will release the closing
60
The shaft 25 is equipped
of the line by switch 9| until ready for a subse
portion 55 (see Fig. 4) and is held thereon by a
suitable flange 58 so that as this chain is pulled
upon, the pulley will rotate on the shaft and
engage'the arm 39.
with sleeve 56a (Fig. 4) which is held securely
thereonl -by means of set screws 51 so as to fix
the sleeve on thel shaft. . A suitable fiexible mem
ber‘58 is attached thereto as at- 58 and wrapped
aboutithe sleeve while a spring 68 is attached to
this flexible member and also to- the framework
of. the machine so’ as tov rotate the shaft tending
to withdraw the member- 28 from the box to` a
position beneath the supporting deck plate. This
spring is. of a character which will apply less
tension than the spring 48 which tends to swing
the member 34 about its pivot 32. The rotation
dueto the action of this spring is limited by the
abutment 52 engaging the shoulder 62 Of a bary
quent operation.
In operation, when the switch 9| is closed and
the post 82 moves downwardly, the pulleys 50,
58' will be oppositely rotated to bring, in the case
of pulley 50, the block 52, and its anti-friction
member 53 thereon into engagement with the
arm 39 of the auxiliary shaft 38. The spring 46v
will be sufñciently strong so that rotation of the
shaft 25 will occur before the auxiliary shaft 38
will turn in its bearings. Accordingly, the'shaft
25 will turn bringing the member 28 from thev po
sition shown in Fig.,1 to the position shown> in.
Fig. 2'whereby the flange 22 of the box` end. I1Y
will be engaged and the box end forced into the
2,410,393
body I8 of the box I6 as shown in Fig. 2. At-this
point the member 28 will have reached the limit
of its stroke having forced the flange 22 so that it
lies against the deck I5 and therefore the shaft
25 can turn no further.
Force, however, being
applied to the arm 39, will then start to rotate
the shaft 38 in its bearings and start to swing
the second member 34 from its position as shown
in Fig. 2 to its position as shown `in Fig. 3, thereby ’
engaging the edge of the box which is away from
the hinge connection and forcing >it into the
sleeve-like box so that this end I1 will be at right
angles to the wall of the box as shown in Fig. 3.
As the member 34 reaches this position, the arm
39 will engage the stop 61 (dotted lines Fig. v5)
mounted in the projecting portion 66 so as to lim
it any further movement of this auxiliary shaft
in its bearings. At this point the mercury switch
will be tipped to break the circuit and the sole
of said members while ¿the other member con
tinues to move the box end into final position.

a supporting deck‘ for the box lprovided with an
