Abstract
Abstract A skirt board and installation arrangement adapted effectively to seal a moving conveyor belt, including skirt board sections interlocked with each other and individually adjustable and removable for replacement, which can be accomplished easily without major tools and without stopping the conveyor belt. The skirt board sections are simple to install individually, or by groups and these operations may be performed while the conveyor belt continues to run and when installed, maintains a proper and effective seal with the belt.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
A skirt board installation for a conveyor having a travelling belt including a mounting plate secured on the vertical walls of a conveyor loading chute, a plurality of skirt board sections capable of contacting said belt, means individually and adjustably mounting said skirt board sections on said mounting plate to permit adjustment of each section toward said belt and to retard movement of each section away from said belt, and said skirt board sections each including generally vertical slides and guideways along their adjoining edges allowing for said adjustment and said movement.
Claim 2
Dependent Claim
92 words
A skirt board installation for a conveyor having a travelling belt including a mounting plate secured on the vertical walls of a conveyor loading chute, a plurality of skirt board sections capable of contacting said belt, means individually and adjustably mounting said skirt board sections on said mounting plate to permit adjustment of each section toward said belt and to retard movement of each section away from said belt, and said skirt board sections each including generally vertical slides and guideways along their adjoining edges allowing for said adjustment and said movement.
Claim 3
Dependent Claim
30 words
A skirt board installation as in claim 1 wherein the individual mounting means comprises cooperating generally vertical guideways and slides allowing for said adjustment of the sections toward said belt.
Claim 4
Dependent Claim
27 words

Claim 5
Dependent Claim
120 words
A skirt board installation for a conveyor having a travelling belt including a mounting plate secured on at least one of the vertical walls of a conveyor loading chute, at least one skirt board section connectible to said mounting plate, a slide and guideway interlocking connection disposed between said mounting plate and said skirt board section allowing generally vertical movement of said skirt board section with respect to said mounting plate and friction means disposed between said mounting plate and said skirt board section adapted to permit sliding of said skirt board section toward said conveyor but to retard movement of said skirt board section away from said belt, said friction means being disposed in said slide and guideway connection.
Claim 6
Dependent Claim
120 words
A skirt board installation for a conveyor having a travelling belt including a mounting plate secured on at least one of the vertical walls of a conveyor loading chute, at least one skirt board section connectible to said mounting plate, a slide and guideway interlocking connection disposed between said mounting plate and said skirt board section allowing generally vertical movement of said skirt board section with respect to said mounting plate and friction means disposed between said mounting plate and said skirt board section adapted to permit sliding of said skirt board section toward said conveyor but to retard movement of said skirt board section away from said belt, said friction means being disposed in said slide and guideway connection.
