There is a similar device in '507 Mechanical Movements' (Lindsay Publications)
"#144. A system of crossed levers, termed "Lazy Tongs". A short alternating rectilinear motion of rod at the right will give a similar but much greater motion to rod at the left. It is frequently used in children's toy. (etc.)"
_/\/\/\/\_
L\/\/\/\/R
(Sorry, my 'picture' doesn't do it justice. The mechanism is mounted on a bracket, anchored/pivoting at the first 'X' from the right. If you pull R right, L will extend left, push R left, L will contract to the right.)
Hope this helped.
