Abstract
A safety inlet apparatus for a paper feed opening of a shredder, with cutting cylinders including an upper casing having a feed end with a safety dam with upper and lower indices. An angled plate means set apart from the upper casing forms the paper feed opening. A safety plate with a distal index end is provided, which is formed to traverse the feed opening from the angled plate to the safety dam. Also included is a pivot, and a power control switch. The pivot is configured to facilitate traversal of the safety plate distal index from the angled plate to the safety dam. The power limit switch is on the upper casing, apart from the pivot member. The traversal of the safety plate distal index end to the safety dam lower index causes the power control switch to stop comminution. A buckle bit plate provides open and closed detents.
