Operation
When a packed box Bis delivered froma con

stop 55 and hook 60 are- depressedallowing the
Vvbox to strike the stop 12. When the boxstrikes
the stop 12, the latter is moved leftvvard against
‘the pressure of the spring'15 as _ shown
n mbv Vthe
dotted line position indicated at a in Figli, thus
i165 allowing the box B to pass over the stop. 55 per
latter'is quickly ejected .from the tabllehl3 onto
a suitable idle roll discharge conveyor 9»I;.by the ¿

is started before vthe table *I3` arrivesfatitsîlower
.most position, the box being vcompletely.dis
charged from» the machine Ill at`- substantially »the
>same time thatthetable, I3-comesto rest. ¿When E
the'ejected boxpas'ses over` the stop 12', the link '
.83 is extended by the spring 84 causing, the stop
12 to be swung upward into position-to «stop the
Vnext box to be received by the tableÁ §I-3.
