A single slot member 6 is mounted on or formed within ¦ second frame section 4.The single slot mernber includes in the ¦¦ embodiment shown by way of example of FIGURE 1 a first extension ; ¦ member 8, second extension member 10 and slide plate 12 inter~
, connecting extension mernbers 8 and 10. A base member 13 mav also be provided opposite slide plate 12 for further connecting ¦ extension members 8 and lO if desired.
First frame section 2 is connected to second frame section ~ I 4 by a single pivo-t member 14 positioned wi-thin'an opening 21 i, I formed in ~:Lrst and second frame sections 2, 4.

A pin member 20is disposed within opening 23 about which single lever 16 is ro-tatable. Pin member 20 is also located at . an intermediate portion of the single lever 16 to allow for at '!' least a 180 pivoting o~ second frame section 4 about first ; 10 frame section 2 by single pivot member 14. A second pin member or roller 22 is connected to one end portion of single lever 16 and is disposed within the single slot member 6 formed within or connected to second frame section 4. The second pin member or roller 22 is therefore slidably mounted within single slot member 6 to provide a lost-motion connection between single lever 16 and second frame section 4.
A power member 24 is also ~rovided for rotating single lever 16 about the pin member 20 and may include a h~draulic drive member or other conventional type of drive mechanisms such as, Eor example, a mechanical worm gear, etc. and which is . -6-i ~ ~ Z~7~
connected to single lever 16 at one end thereof.
