Abstract

A rectangularly-shaped debris-conveyor chute section (10) which can be nested with other sections to form a debris chute has a side opening (30) for receiving items to be conveyed by the chute. The side opening (30) has a rotatable door/ledge assembly (32) mounted thereat which can be rotated, as a unit, into the chute opening to bring a ledge thereof flat against a sidewall (22) of the chute section covering the opening (30) or out of the chute opening to bring the ledge perpendicular to the sidewall (22) of the chute and the door over the opening in the sidewall. A baffle (62) is placed on the inside of the sidewall immediately above the side opening to protect the door/ledge assembly (32) from items falling through the chute. Hoisting eyelets (64) are located on the interior of each chute section so that they can be reached through the opening. The conveyor chute sections are mounted inside a building by means of screw jacks (72) attached to the rotatable door/ledge assemblies.

Dependent claims

A portable gravity conveyor chute section of a type which can be nested with other conveyor chute sections to form a gravity conveyor chute, the section comprising a sidewall having basically a tubular shape which guides items falling through a bore thereof, said section having an upstream end opening for receiving items dropped into said section from above, and a downstream end opening for discharging said items passing through the bore of said section, said downstream end being selectively engagable with the upstream end of an adjacent section to form said conveyor chute to be longer than a single section whereby items serially fall through the bores of said thusly engaged sections, said section further defining a side opening through the sidewall thereof at a position intermediate said upstream and downstream ends through which items can be dropped into the bore of said section, said section including a unitary door/ledge assembly mounted at said side opening, said door/ledge assembly comprising a door frame and a ledge member being fixedly attached together, and a hinge to hingedly attach said unitary door/ledge assembly at an edge of said side opening for allowing said door frame to be rotated inwardly into the bore of said chute section, thereby making the outside shape of said chute section more streamline, and to be rotated outwardly, thereby closing said door frame on the inside of the side opening with said ledge member extending away from said sidewall, and wherein is further included a door mounted on said door frame, whereby said door/ledge assembly forms a ledge and door for said side opening when it is rotated outwardly said door including latching means for selectively preventing said door from opening.

A portable gravity conveyor chute section of a type which can be nested with other conveyor chute sections to form a gravity conveyor chute mounted on the outsides of buildings, the section comprising a sidewall having basically a tubular shape which guides items falling through a bore thereof, said section having an upstream end opening for receiving items dropped into said section from above, and a downstream end opening for discharging said items passing through the bore of said section, said downstream end being selectively engagable with the upstream end of an adjacent section to form said conveyor chute to be longer than a single section whereby items serially fall through the bores of said thusly engaged sections, said section further defining a side opening through the sidewall thereof at a position intermediate said upstream and downstream ends through which items can be dropped into the bore of said section, said section including a door covering said side opening and being hingedly attached to said sidewall, said door including latching means for selectively preventing said door from opening;

said conveyor chute section further including a baffle means positioned on and attached to the inside surface of said section adjacent said side opening said baffle means including an inwardly, downwardly sloping surface to deflect items falling through said section inwardly and including a tie means for receiving a hoisting line hook of a hoisting device for lifting said section, said tie means being accessible to someone outside said section reaching through said side opening, whereby, said portable section can be positioned on the outside of a building with said side opening facing said building, a hoisting device for lifting and manipulating said section can be made to extend a hoisting line having a hook on the end thereof through said upstream end opening of said conveyor chute section for positioning said hook near said side opening and someone from within said building can reach through said side opening and engage or disengage said hoisting line hook from said tie means without getting outside said building and said section.

said conveyor chute section further including a baffle means positioned on and attached to the inside surface of said section, said baffle means including an inwardly, downwardly sloping surface to deflect items falling through said section inwardly and a tie means positioned on and contacting the inside surface of said section adjacent said side opening, downstream of said baffle means, for receiving a hoisting line hook of a hoising device for lifting said section, said baffle means preventing falling items from contacting said tie means, said tie means being accessible to someone outside said section reaching through said side opening, whereby, said portable section can be positioned on the outside of a building with said side opening facing said building, a hoisting device for lifting and manipulating said section can be made to extend a hoisting line having a hook on the end thereof through said upstream end opening of said conveyor chute section for positioning said hook near said side opening and someone from within said building can reach through said side opening and engage or disengage said hoisting line hook from said tie means without getting outside said building and said section.
