Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
247 words
In food conveyor construction, a support platform having an inverted channel-shape; the platform having a generally flat top with side edges, and first and second longitudinal side flange means extending downwardly and inwardly of said side edges; belt rolls at the ends of the platform; means removably mounting the rolls on the platform; adjustable means for retracting at least one of the rolls toward the other; pan means extending in spaced relation below the platform; first and second trough-forming flange means extending upwardly and longitudinally of the platform at the side edges thereof; quick-release means removably mounting the pan means and trough-forming flange means on the platform side flange means; an endless loop belt looped around the rolls with one run extending along and supported by the flat platform top between the trough-forming flange means; and with the other run extending below the platform top between the flat top and pan means; power drive means for the belt mounted on the platform, releasably engaging one of the rolls; and leg support means mounting the platform in cantilever-fashion including at least front and rear upwardly extending members, said members being connected to the platform first longitudinal side flange means whereby said belt means can be completely removed from the conveyor by laterally moving the belt means beyond the second side flange means after removal of the second trough-forming flange means and the pan means and after retracting one of said rolls to release the tension in said belt.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
50 words
The construction defined in claim 1 in which the leg support members each have vertical strut means; in which one of the strut means is pivotally adjustably Connected to said first plat-form side flange means; and in which at least one of the strut means is longitudinally adjustable in length.
Claim 4
Dependent Claim
21 words
The construction defined in claim 2 in which each leg member has spaced rollers mounted thereon stably to support the platform.
Claim 5
Dependent Claim
37 words
The construction defined in claim 2 in which a brace is pivotally connected at one end to the platform first side flange means, and is adjustably connected at its other end to pivotally connected vertical strut means.
Claim 6
Dependent Claim

The construction defined in claim 4 in which cross brace means is connected within the platform channel to the platform side flange means adjacent the pivotal strut and brace connections.
Claim 7
Dependent Claim
55 words
The construction defined in claim 1 in which the removable mounting of the rolls on the platform includes notch means formed in struts movably mounted on certain of the ends of the platform side flange means, bearing blocks slidably removably mounted in said notch means, and roll stub shafts removably journaled in said bearing blocks.
Claim 8
Dependent Claim
30 words
The construction defined in claim 6 in which the power drive means includes a quill, and in which one of the rolls has a releasable spline connection with said quill.
