The central wall of channel bar 32 is formed with a
number of spaced openings 320. There is one opening
320 corresponding to the top end of each vertical slot 31
in bracket 29. A drilled collet 35 extends through each
slot 31. The collar of each collet overlaps the edges of
the slots 31 so that when a sheet metal bolt 36 is posi
tioned through the collet and fastened to the adjacent
opening 34 in channel bar 32, the channel bar will then
be movable vertically as far as the length of the slots 31
will allow, and the bolts 36 will not ‘bind in the slots.
The normal position of the channel bar 32 relative to
bracket 29 is the upper position shown in FIG. 2. In
order to prevent the channel bar 32 from slipping down
a bolt 37 is provided spaced above one of the slots 31.
A coil spring 38 is attached at one end to the bolt 37 and
at the opposite end to the bolt 36 which extends through
the slot to the channel bar 32. Thus the channel bar
may be pulled downwardly against the restraint of the
spring by any known means common to the art, such as
a coin-operated lever system. The channel bar or slider
because the two arms 59 and 60 are crossed, the spring
61 tends always to pull the two hooks 57 and 58 apart.
The channel bar or slider 32 can be moved downwardly
by pulling on bolt 36a and will be returned upwardly to
its original position by spring 38 as shown in FIG. 1.
The hooks 57 and 58 of the climber 40 can pivot side
ways until they hit each other or the side ?anges 47 of
channel strip 46. The starting position of the climber is
on the lowest pair of opposed notches 17 and 34 with
hook 57 engaging the lower edge 34b of the notch 34
and hook 58 engaging the lower edge 17a of the opposite
notch 17. As the channel bar 32 is moved downwardly,
the upper inclined edge 34a of notch 34 begins to push
hook 57 sideways towards hook 58. Then the edge 33
keeps hook 57 over (FIG. 4) until the channel bar is all
the way down, at which point the next above notch 34
comes into position, and hook 57 is pulled over into
that notch by spring 61. As the channel bar begins to
return, the hook 57 will be pulled upwardly by the lower
edge 34b of the notch which the hook engages. As hook
57 is pulled upwardly by the channel bar or slider, the
entire climber will be pulled upwardly and the other hook
will be raised and returned to its normal upper position
by the spring 38 upon release of the slider. One of the
bolts 36a has been made longer than the other bolts 36
in order to provide a connection to the system for pulling
down the channel bar.
A movable climber 40 is provided for movement be
tween the edge 16 of wall 11 and the edge 33 of flange
32b. The purpose of the climber 40 is to release the
clined edge 17b of the ?rst notch 17. Hook 58 will be
held over by edge 16 of wall 11 (FIG. 5) until the
climber has been lifted all the way to the next above
notch 17. At that point hook 58 will spring over into the
notch 17 and climber will be in its original condition but
