Abstract
Abstract A conveyor apparatus including a frame, a conveyor mounted on the frame and a drive mechanism for moving the conveyor on the frame. The conveyor includes an endless conveyor member having a plurality of slat members disposed in side-by-side relation which provide inner and outer reach portions, a plurality of rotatable members mounted on the frame to rollingly support the outer reach portion and a slide support member is carried by the frame for slidably supporting the inner reach portion. The drive mechanism includes one or more flexible, endless drive elements operably connected to the outer reach portion for moving the conveyor member with respect to the frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
220 words
In a conveyor apparatus comprising, a frame, a conveyor member mounted on said frame including a plurality of slat members disposed in endless side-by-side relation and defining inner and outer reach portions, a drive mechanism including a pair of endless, flexible drive elements mounted adjacent the opposed ends of said slat members, said slat members extending in overlying relation with respect to said drive elements along said outer reach portion, said drive mechanism including spaced sprocket members disposed for driving engagement with said drive elements for driving said conveyor member lengthwise of said frame, roller support means mounted on said frame disposed between opposed ends of said slat members, a plurality of elongated roller members journaled for rotation on said roller support means and having their axes of rotation disposed generally parallel to the lengthwise dimension of said slat members, said drive elements being disposed inwardly from said frame and outwardly from the opposed ends of said roller members along said outer reach portion, slide support means carried by said frame and disposed inwardly of said outer reach portion for slidably supporting said inner reach portion, and said slat member defining said outer reach portion rollingly engaging said roller members for movement lengthwise of said frame and relative to said roller members for minimizing the loading on said drive mechanism.
Claim 2
Dependent Claim
220 words
In a conveyor apparatus comprising, a frame, a conveyor member mounted on said frame including a plurality of slat members disposed in endless side-by-side relation and defining inner and outer reach portions, a drive mechanism including a pair of endless, flexible drive elements mounted adjacent the opposed ends of said slat members, said slat members extending in overlying relation with respect to said drive elements along said outer reach portion, said drive mechanism including spaced sprocket members disposed for driving engagement with said drive elements for driving said conveyor member lengthwise of said frame, roller support means mounted on said frame disposed between opposed ends of said slat members, a plurality of elongated roller members journaled for rotation on said roller support means and having their axes of rotation disposed generally parallel to the lengthwise dimension of said slat members, said drive elements being disposed inwardly from said frame and outwardly from the opposed ends of said roller members along said outer reach portion, slide support means carried by said frame and disposed inwardly of said outer reach portion for slidably supporting said inner reach portion, and said slat member defining said outer reach portion rollingly engaging said roller members for movement lengthwise of said frame and relative to said roller members for minimizing the loading on said drive mechanism.
Claim 3
Dependent Claim
56 words
In a conveyor apparatus in accordance with claim 1, wherein said drive element is disposed in spaced relation from said slat members, and said slide support means is disposed between said drive element and said slat members for supporting the respective slat members of said inner reach portion in suspended relation with respect to said frame.
Claim 4
Dependent Claim
66 words
In a conveyor apparatus in accordance with Claim 1, wherein each of said slat members is operably connected to said drive element by a bracketlike member, and said bracketlike member includes an outwardly projecting plate member which is disposed for sliding engagement with said slide support means for supporting the respective slat members of said inner reach portion in suspended relation with respect to said frame.
Claim 5
Dependent Claim
59 words
In a conveyor apparatus in accordance with claim 3, wherein each of said bracketlike members includes a flange portion projecting outwardly from the respective plate member and attached adjacent its free end to a respective one of said slat members, and said slide support means slidably supports the respective plate members adjacent the ends remote from said flange portion.
Claim 6
Dependent Claim
61 words
In a conveyor apparatus in accordance with claim 1, wherein said drive element comprises a looplike chain member having a plurality of link members interconnected to one another at their opposed ends by common pin members, and said drive mechanism includes spaced sprocket members disposed for driving engagement with said chain member for driving said conveyor member lengthwise of said frame.
Claim 7
Dependent Claim
72 words
In a conveyor apparatus in accordance with claim 1, wherein said drive element includes a plurality of link members interconnected by spaced pin members, and wherein the spacing between the axes of the respective pin members corresponds substantially to the width of the respective slat members whereby the adjacent edges of said slat members are disposed in close proximity to one another as they move along the inner and outer reach portions.
Claim 8
Dependent Claim
65 words
In a conveyor apparatus in accordance with claim 1, wherein each of the respective of said slat members is operably connected to said drive element by a bracketlike member, said bracketlike member including an outwardly projecting plate member detachably connected thereto, and said drive element being connected to said plate member and supported in suspended relation from said slat members adjacent said outer reach portion.
Claim 9
Dependent Claim
48 words
In a conveyor apparatus in accordance with claim 1, wherein said slide support means includes at least one raillike member mounted on said frame between said inner and outer reach portions, and a bearing member is carried by said raillike member for slidably supporting said drive element thereon.
