Abstract
A flexible endless belt mountable on rotating elements has an outer and inner surface between first and second lateral edges and a plurality of longitudinally spaced-apart laterally oriented upraised flights on the outer surface. Each flight has a single medial portion offset in a rearward longitudinal direction from portions of the flight immediately lateral to the medial portion. Protrusions on the inner surface engage the rotating elements for endlessly rotating the endless belt in a forward longitudinal direction. Such an endless belt is particularly useful on a control apparatus for a stone slinger.
Claims19
A flexible endless belt mountable on rotating elements comprising:
- an outer and inner surface between first and second lateral edges;
- a plurality of longitudinally spaced-apart laterally oriented upraised flights on the outer surface, each flight having a single medial portion and end portions, the medial portion offset in a rearward longitudinal direction from the end portions and from portions of the flight immediately lateral thereto, the medial portion thicker than the end portions;
- and
- engagement means on the inner surface for engagement with the rotating elements for endlessly rotating the endless belt in a forward longitudinal direction.
A flexible endless belt mountable on rotating elements comprising:
- an outer and inner surface between first and second lateral edges;
- a plurality of longitudinally spaced-apart laterally oriented upraised chevron-shaped flights extending from the first lateral edge to the second lateral edge on the outer surface, each chevron-shaped flight having a single vertex pointing in a rearward longitudinal direction, each flight having a middle portion proximal the vertex and end portions laterally offset from the middle portion, the middle portion being thicker and higher than the end portions, each flight having a leading edge and trailing edge extending laterally on the outer surface of the belt, the leading edge being longitudinally forward of the trailing edge, the leading edge forming a first angle with the outer surface that is steeper than a second angle formed between the trailing edge and the outer surface, each flight having a top that is flat and parallel to the outer surface along at least part of the middle portion, the top of each flight tapering downwardly in the end portions towards the lateral edges;
- and,
- two or more laterally-aligned spaced-apart longitudinal rows of protrusions on the inner surface laterally inward of the rotating elements for engagement with the rotating elements for endlessly rotating the endless belt in a forward longitudinal direction and for maintaining alignment of the endless belt on the rotating elements.
