Document conveying system

A chute system for conveying articles from an upper elevation to a lower elevation within a building, said chute system comprising:

• a vertical post defining an axis of rotation;
• an outer wall concentric with said post;
• and
• a helical chute wound around said vertical post and being secured at an inner edge to said post and at an outer edge to said outer wall;
• and wherein said chute comprises a plurality of chute segments secured together in stepped relationship to each other:
• each chute segment having an upper wall disposed at a first angle to the post and sloping downwardly toward the outer wall;
• and wherein the first angle is between 3 and 6 degrees to the vertical post.

• each chute segment having an upper wall disposed at a first angle to the post and sloping downwardly toward the outer wall, and wherein the upper wall of each chute segment is further disposed at a second angle relative to the horizontal and slopes generally downwardly toward the lower end of the post;
• and the second angle is between 50 and 70 degrees to the horizontal.

• an outer wall concentric with said post;

• and wherein said chute comprises a plurality of chute segments secured together in stepped relationship to each other:
• each chute segment having an upper wall disposed at a first angle to the post and sloping downwardly toward the outer wall:
• and wherein a first plurality of chute segments are joined together to a length of post and to a length of outer wall to form a first helix that spirals through one hundred and eighty degrees;
• and a second plurality of chute segments are joined sequentially together to a second length of post and to a second length of outer wall to form a second helix that spirals through one hundred and eighty degrees;
• and wherein the first and second helixes are secured together in end-to-end relation to form a continuous chute that resembles a stepped spiral staircase.
