Abstract
Abstract A slat link for endless conveyor belts for heavy materials handling has a central transverse reinforcing beam and slat link covers surrounding the transverse reinforcing beam which converge to either side of the beam at a point intermediate the vertical distance between the top and bottom portions of the beam. Material loaded on top of the conveyor slat links contacts the higher portion of the slat link at the portion of the slat link where the beam is located, the beam acting to distribute the shock from the material loaded thereon along its links and to transmit such shock loadings to the conveyor support structure which absorbs the shock.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
A conveyor slat link comprising a central transverse beam, top and bottom cover plates spanning said beam and having flat central portions lying against and attached to the top and bottom surfaces, respectively, of said beam and tapered side portions extending laterally outward of said beam along each side thereof and converging toward each other in a direction outwardly away from said beam, and a plurality of spaced tubular members located at and attached to and joining the outer ends of the said converging tapered side portions away from said central portions, the tubular members at the respective sides of said transverse beam being disposed longitudinally along the length of said slat link parallel to said transverse beam and in longitudinally aligned spaced relation so that a second slat link having mating tubular members may be pivotally connected thereto by a single transversely extending axle shaft, the said side portions of said cover plates extending between the said tubular members and said beam at each side thereof converging outwardly of said beam to their junctures with said tubular members.
Claim 2
Dependent Claim
179 words
A conveyor slat link comprising a central transverse beam, top and bottom cover plates spanning said beam and having flat central portions lying against and attached to the top and bottom surfaces, respectively, of said beam and tapered side portions extending laterally outward of said beam along each side thereof and converging toward each other in a direction outwardly away from said beam, and a plurality of spaced tubular members located at and attached to and joining the outer ends of the said converging tapered side portions away from said central portions, the tubular members at the respective sides of said transverse beam being disposed longitudinally along the length of said slat link parallel to said transverse beam and in longitudinally aligned spaced relation so that a second slat link having mating tubular members may be pivotally connected thereto by a single transversely extending axle shaft, the said side portions of said cover plates extending between the said tubular members and said beam at each side thereof converging outwardly of said beam to their junctures with said tubular members.
Claim 3
Dependent Claim
26 words
A conveyor slat link as described in claim 1 wherein a plurality of said slat links are pivotally connected together to form an endless conveyor belt.
Claim 4
Dependent Claim
74 words
A conveyor slat link as described in claim 1 in which said transverse beam is an I-beam and said cover plates have flat central portions lying flat against and attached to the flat surfaces of the top and bottom flanges of said I-beam, said tubular members and the junctures of said cover plates therewith being located entirely between and spaced from the planes of the said flat surfaces of the flanges on said I-beam.
Claim 5
Dependent Claim
26 words
A conveyor slat link as described in claim 1 in which said slat link further includes upstanding side members to retain conveyed material on said link.
