Abstract
Abstract A cargo carrying structure is adapted to move along a path defined by a frame while supported by a plurality of chains. A plurality of sprocket sets, each including an inner and an outer sprocket, are supported by the frame and engaged by the chains. A plurality of rods which connect the outer chains to the cargo carrying structure are arranged to pass between the teeth of the inner sprockets. The rods are connected to intermediate connecting members which carry rollers engaged by roller guides. At least one of the chains is formed by a multiplicity of links that span a predetermined number of sprocket teeth and a lesser number of adjusting links that span a different number of sprocket teeth. The adjusting links are positioned in the chain so that the rods pass through the unfilled spaces between the teeth of the inner sprockets.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
248 words
A cargo transporting conveyor apparatus comprising a frame defining a path along which the cargo can be moved, a cargo carrying structure adapted to be moved along the path defined by the frame, a plurality of chains connected to and supporting the cargo carrying structure including adjacent each of two sides of the cargo carrying structure at least one outer chain and at least one inner chain disposed between said at least one outer chain and a side of the cargo carrying structure, a plurality of sprocket sets supported by the frame which engage the links of the chains, each sprocket set comprising an inner sprocket and an outer sprocket, a plurality of rods connecting to the cargo carrying structure at least one outer chain and at least one inner chain on each of said two sides of the cargo carrying structure and arranged to pass between the teeth of the inner sprockets, at least one of the chains being formed by a multiplicity of links that span a predetermined number of sprocket teeth and a lesser number of adjusting links that span a different number of sprocket teeth, the adjusting links being positioned in the chain so that the rods pass through the unfilled spaces between the teeth of the inner sprockets, and a link of each inner chain adjacent a rod connecting an outer chain to the cargo carrying structure being configured to permiT the rod to lie generally in a plane of the inner chain.
Claim 2
Dependent Claim
248 words
A cargo transporting conveyor apparatus comprising a frame defining a path along which the cargo can be moved, a cargo carrying structure adapted to be moved along the path defined by the frame, a plurality of chains connected to and supporting the cargo carrying structure including adjacent each of two sides of the cargo carrying structure at least one outer chain and at least one inner chain disposed between said at least one outer chain and a side of the cargo carrying structure, a plurality of sprocket sets supported by the frame which engage the links of the chains, each sprocket set comprising an inner sprocket and an outer sprocket, a plurality of rods connecting to the cargo carrying structure at least one outer chain and at least one inner chain on each of said two sides of the cargo carrying structure and arranged to pass between the teeth of the inner sprockets, at least one of the chains being formed by a multiplicity of links that span a predetermined number of sprocket teeth and a lesser number of adjusting links that span a different number of sprocket teeth, the adjusting links being positioned in the chain so that the rods pass through the unfilled spaces between the teeth of the inner sprockets, and a link of each inner chain adjacent a rod connecting an outer chain to the cargo carrying structure being configured to permiT the rod to lie generally in a plane of the inner chain.
