Abstract
Abstract Articles being transported upwardly on an inclined conveyor are restrained against rolling back down the conveyor by a brake comprising an array of parallel spaced apart rods extending longitudinally in the direction of conveyor movement, pivotally suspended at one end and disposed to impose weight on each article, holding it against the moving conveyor to insure progression in the desired direction only.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
An article roll back brake for an inclined conveyor comprising, in combination, an array of elongate parallel spaced apart downwardly convexed longitudinal elements disposed longitudinally in the direction of movement of the inclined conveyor, a brake frame arranged and disposed to support said array at a preselected distance above the inclined conveyor, a pivot arm having one end pivotally connected to said brake frame and another end pivotally connected to said array, and stop means disposed to arrest the downward pivotal movement of the other end of said array at a preselected point out of impingement on the conveyor, whereby dual pivotal movement of said array occurs at the end of said array opposite the end at which said stop means is disposed.
Claim 2
Dependent Claim
123 words
An article roll back brake for an inclined conveyor comprising, in combination, an array of elongate parallel spaced apart downwardly convexed longitudinal elements disposed longitudinally in the direction of movement of the inclined conveyor, a brake frame arranged and disposed to support said array at a preselected distance above the inclined conveyor, a pivot arm having one end pivotally connected to said brake frame and another end pivotally connected to said array, and stop means disposed to arrest the downward pivotal movement of the other end of said array at a preselected point out of impingement on the conveyor, whereby dual pivotal movement of said array occurs at the end of said array opposite the end at which said stop means is disposed.
Claim 3
Dependent Claim
39 words
Apparatus according to claim 1 wherein the downwardly convexed longitudinal elements each include a straight linear portion disposed substantially parallel to the inclined conveyor surface when the downward pivotal movement of said array is arrested by said stop means.
Claim 4
Dependent Claim
14 words
