below the shaft 23. The opposite ends of the
shaft 58 are journalled in bearings on the side
plates II respectively. The shaft 58 has its axis 45
disposed coincident with the center from which _
the semi-circular portion of the guideway is
struck. A pair of similar disks 59 are fast on the
shaft 58 in proximity to the plates ll. Each of
the disks has a plurality of notches 66 in the 50
periphery thereof, there being ten notches 60 in
the present instance in keeping with the size and
number of the sign units 35 used. The notches
69 in the disks 59 cooperate with the portions 44
of the carriers 36 as the units 35 are presented
by gravity one at a time from the guideway run
46 and transfer the units 35 to a point where
they are picked up one at a time by means pres

each unit 35. As the unit moves upwardly the
portions 44 cam the pawls 69 against the action
of the springs ‘II to clear the same, after which,
under the reaction of the springs, the upper ends
of the pawls reengage the portions 44, thereby
checking the unit in the up position just as the
lugs 64 clear the same.
As each of the units 35 reaches its up position
it crowds the preceding units by reason of the
contact of the guide rollers 4|._ This causes the
units to traverse the upper curved ends 49 under
power transmitted by the chains 63 and their lugs
64 until the units 35 reach the down sides of said
ends 49, whereupon the units drop by gravity into
