| Ferraris truss | Mining | Supporting batten used originally as a slanting support under a shaking screen. When the screen was pushed forward the radial motion of the truss caused it to rise slightly, giving a throwing motion to the load and aiding the gravity-assisted return as the reciprocating action of the screen vibrator was reversed. The principle is used in shaking tables such as the James. (references) | |
