Automatic Debris removal system

A method of removing roofing construction debris to ground level for disposal, said method comprising the steps of:

• providing a telescoping construction hoist of the type having a plurality of elongated extension members being traversed by a carriage device and controlled by a cable/winch system;
• positioning said hoist at a predetermined angle relative to said building;
• supplying a tilting bucket means including a linkage arm assembly being pivotally attached to said bucket means;
• mounting said tilting bucket means on said carriage in operative relation thereto;
• installing an automatic release mechanism on said carriage in functional relation to said bucket means;
• attaching a debris removal chute to said hoist capable of receiving said roofing debris;
• positioning said chute on said hoist at a predetermined location in adjustable relation thereto;
• transporting said bucket means on said hoist to said roof by operation of said cable/winch system;
• filling said bucket means with roofing debris to be disposed of;
• and
• lowering said bucket means with said cable/winch system to a predetermined location on said hoist such that said automatic release mechanism comes into direct contact with a stop device on said chute thereby automatically dumping said debris into said chute for disposal.

In a construction hoist of the type having a plurality of telescoping members, a winch operated cable system for transporting a carriage along said telescoping members from a lower position adjacent ground level to an upper position on a building for removing construction materials from said upper position to said lower position for delivery into a container member in a tilting bucket pivotally attached to said carriage and pivotally movable between a loading position and an unloading position, an automatic debris removal device, comprising:

• an elongated chute for receiving debris from said bucket at said unloading position, said chute having an upper end pivotally attached at said lower position to said telescoping members at a first transverse member limiting downward movement of the carriage;
• locking means cooperating between said carriage and said bucket for maintaining said bucket in said loading position in a latched condition and permitting pivotal movement of said bucket to said unloading position in an unlatched condition;
• and
• automatic releasing means on said carriage device operatively connected with said locking means and coacting upon engagement with said first transverse member at said lower position as said carriage moves from said upper position to said lower position to move said locking means from said latched condition to said unlatched condition whereby said bucket is automatically released from said loading position to said unloading position to dispose of debris contained therein onto said chute and into the container.
