The Rodent-Sized Catapult invented by Gadget
represents a cross between the Plunger Elevators
and a rocket.
The Rodent-Sized Catapult can be used for high-speed delivery of materials
(or creatures), as Gadget demonstrated in
"A Creep in the Deep" (#28).
The device is placed on a small cart, which has wheels made from
screw-nuts and a handle for convinient moving.
The shooting part of the device is placed on the inclined board, which
is attached to the base with a nail.
It is fired by using a rubber band and a spring. In a trim the spring
and the rubber band are held by a pawl. When the pawl is released
the rubber band snaps forward and pushes the "arrow". The spring increases
the speed.
After the suck cup is reach its target, a second part of the mechanism
is beginning to work. A rope is used for joining the suck cup with a
rocket, which is fixed to a long pole. The pole inserted into a special
socket at the end of the pole.
A jet thrust helps to quickly lift an object, whish is thrilled by a suck
cup.
