One end of the link member 98 is connected with the
horizontal ?ange 92 of the frame member 84- by a pin

the effective length of the linkage system provided by the
link members 98 and 1% may be adjusted for controlling
that many structural details may be changed without de
parting from the spirit and scope of the appended claims.
The invention is claimed as follows:
