Abstract
Individual longitudinal channels equipped with closely spaced wheels running the full length of the conveyor and suspended in a natural catenary fashion by cross support cables is disclosed.
Claims5
In a belt conveyor;
- a frame;
- an endless belt of a flexible material;
- a support for said belt including a plurality of pairs of spaced apart, longitudinally extending frame channel members arranged in spaced-apart back-to-back relationship, said pairs of channel members having a plurality of diametrically related wells spaced along the longitudinal length of said channel members;
- spacers between said channel members operative to maintain said channel members in parallel, spaced-apart relationship, each of said spacers being located at the ends of the sections of said channel members and arranged so as to be common to the adjacent ends of adjacent channel members;
- a roller support having laterally extending shaft members supported in each related pairs of said wells and in position to engage the undersurface of the load run of the flexible endless belt;
- flexible stranded steel cable cross-suspension members spaced along and connected to said frame, said flexible cable passing through preformed openings provided in said spacers at a point between adjacent channel sections and operative to support said pairs of channel member sections in longitudinal, straight-line relationship relative to each other to maintain said supporting rollers in supporting engagement with said belt;
- and,
- locking means engageable within the openings in said spacers and with said flexible stranded cable to lock said channel member sections in longitudinally aligned, spaced-apart parallel relationship.

In a belt conveyor;
- a frame;
- an endless belt of a flexible material;
- a support for said belt including a plurality of spaced-apart, longitudinally extending frame members, said frame members each include a pair of longitudinally extending channel members arranged in spaced-apart, back-to-back relationship, said channel members of each of said frame members being formed in sections, said pairs of channel members having a plurality of diametrically related wells spaced along the longitudinal length of said channel members;
- spacers between said channel members operative to maintain said channel members in parallel, spaced-apart relationship, each of said spacers being located at the ends of the sections of said channel members and arranged so as to be common to the adjacent ends of adjacent channel members;
- a roller support having laterally extending shaft members supported in each related pair of said wells and in position to engage the undersurface of the load run of the flexible endless belt;
- a flexible support means connected to said frame and extending transversely to the run of the conveyor belt, said flexible support means being operably connected to maintain said frame members in catenary supporting relationship with respect to said conveyor belt and to support said pairs of channel members in longitudinal, straight-line relationship relative to each other to effect the supporting engagement of said rollers with said conveyor belt, said flexible support means passing through said spacers and being operatively connected to maintain said channel members of said frame members in longitudinally aligned, spaced-apart parallel relationship;
- and,
- locking means engageable with said flexible support means and said spacers to effectively lock said spacers to said flexible support means.
