Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
195 words
A conveyor assembly comprising a pair of elongated, spaced, parallel frames, each frame including an upper, longitudinally extending flange, an elongated endless material-handling member including an upper reach supported by said upper flanges for parallel movement relative thereto, each frame including a generally vertical side wall having inner and outer sides, at least one of said frames including an inclined web between the associated upper flange and side wall, said web extending outwardly and downwardly from the upper flange and said conveyor member to provide vertical and horizontal spacing between the conveyor member and side wall for easy transfer of materials to and from the conveyor member along its longitudinal edge adjacent said inclined web, said upper flanges projecting inwardly and outwardly from the upper marginal edges of said webs from which said upper flanges are supported, each of said upper flanges having a channel shaped wear strip engaged thereover from which the opposite marginal portions of said upper reach are slidingly supported, the spacing between the inner sides of said side walls being greater than the width of said conveyor member, said conveyor member including a lower return reach received between said side walls.
Claim 2
Dependent Claim
195 words
A conveyor assembly comprising a pair of elongated, spaced, parallel frames, each frame including an upper, longitudinally extending flange, an elongated endless material-handling member including an upper reach supported by said upper flanges for parallel movement relative thereto, each frame including a generally vertical side wall having inner and outer sides, at least one of said frames including an inclined web between the associated upper flange and side wall, said web extending outwardly and downwardly from the upper flange and said conveyor member to provide vertical and horizontal spacing between the conveyor member and side wall for easy transfer of materials to and from the conveyor member along its longitudinal edge adjacent said inclined web, said upper flanges projecting inwardly and outwardly from the upper marginal edges of said webs from which said upper flanges are supported, each of said upper flanges having a channel shaped wear strip engaged thereover from which the opposite marginal portions of said upper reach are slidingly supported, the spacing between the inner sides of said side walls being greater than the width of said conveyor member, said conveyor member including a lower return reach received between said side walls.
Claim 3
Dependent Claim
23 words
The structure set forth in claim 1 wherein said conveyor assembly includes fastening means extending transversely between the side walls of said frames.
Claim 4
Dependent Claim
27 words
The structure set forth in claim 2 wherein said fastening means includes roller means disposed between said frames supporting said lower return reach of said conveyor member.
Claim 5
Dependent Claim
83 words
The combination of claim 1 wherein said side walls include means defining outwardly opening ''''T'''' mounting channels extending along the upper marginal edge portions of said side walls, the last mentioned means including downward and outward inclined extension portions of the lower marginal edge portions of said inclined webs projecting outwardly of the outer sides of said side walls, whereby the upper surface portions of said inclined webs define sloped spillage drainage surfaces for said frames as well as said ''''T'''' mounting channels.
