Filling system for a silo

A filling system for a silo, wherein the silo is of the type having side and top walls, said filling system comprising:

• a. a fill opening located at an upper end of a sidewall and communicating with the interior of the silo,
• b. a normally closed openable fill opening closure operably associated with the fill opening,
• c. a delivery duct disposed outwardly of the silo and extending therealong for delivery of fill material to said fill opening,
• d. deflector means mounted inside the silo at a generally central location at an upper portion thereof,
• e. vent means for releaving gaseous pressure in the silo during the filling thereof, the vent means consisting of a vent opening in an upper portion of said silo and a baffle-type deflector for deflecting dust particles away from said vent opening,
• f. a normally closed openable vent closure operably associated with the vent opening,
• g. means operably associated with both said fill opening closure and said vent opening closure for simultaneous remote opening of both said fill opening closure and said vent opening closure from a location at the bottom of the silo outside thereof, the remote means comprising,
• 1. a cable-like tension means having spring assist means operably associated with both said fill opening closure and said vent opening closure to facilitale opening of said fill opening closure and said vent opening closure against gravity forces induced by said tension means and that would otherwise urge said closures toward a closed position, and
• 2. spring-biased latch means mounted at a location at the bottom of the silo outside thereof and operably associated with said cable-like tension means for controlling the tension in said cable-like tension means thereby simultaneously controlling the operation of both said fill opening closure and said vent opening closure.
