a suns-SHEET z.
BY #MM l1 TTORNEY WIT/V588 be made in sizes adapted to difierent sizes of coal, such as egg, broken, stove, chestnut, pea, etc. It can also be made any howht, in sections from ten to sixteen feet, or in such other lengths as may be suited to the prevail ng conditions and intended uses.
The outer flange on the floor-plates pre vents or helps to reduce ear against the edge of the upright band or Wall B: italso prevents or helps to reduce outside leakage of Water or dust and it strengthens the floorplate itself. The inner flange has similar functions, that is, it prevents leakage of Water or fine coal dust against the post, strengthens the floor-plate and prevents Wear against the post. These flanges practically confine the Wear to the floor-plates wh ch lessens the cost of repair parts.
The floor-plates may also be of utility in spiral separators and the term spiral chutes is used broadly, so as to include the various utilities to which the invention is applicable.
1 Having thus described the invention, What I claim as new and ters Patent is:
1. A. spiral chute, comprising a central post, helical floor-plates having upturned outer and inner flanges, said fioor-piates being secured to said post and bearing at their inner edges against said post to form a runway of which the post is the inner Wall, the lower portion of said runway having its inner edge spaced away from the post and having an inner downturned flange.
2. A spiral chute, comprising a central post, he al floor-plates having upturned outer and inner flanges, said floor-plates be ing secured to said post and hearing at their inner e-i ges against said post to form a runway of which me post is the inner wall, the inner portion of the lower end of the runway being cut away and having its inner edge spaced away from the post.
