Abstract:
1. A safety inlet apparatus for a paper feed opening of a shredder having cutting cylinders with comminution blades thereon, comprising: an upper deck of the shredder, the upper deck having a feed end with a safety dam, wherein the safety dam includes a top portion and a bottom portion; an angled plate set apart from the upper deck forming at least a portion of the paper feed opening; a safety plate formed to traverse the paper feed opening from the angled plate to the safety dam, the safety plate having a distal index end; a pivot member coupled between the safety plate and the upper casing, wherein the pivot member is positioned at least partly proximally to the upper casing, and is configured to facilitate cantilevered traversal of the safety plate distal index end from the angled plate to the safety dam; and a power limit switch disposed on the upper casing and distally set apart from the pivot member, the power limit switch preventing comminution when activated; wherein the cantilevered traversal of the safety plate distal index end from the angled plate to a top portion of the safety dam exposes the paper feed opening for shreddant feeding and allows comminution by the shredder cutting cylinders; and wherein the cantilevered traversal of the safety plate distal index end to a bottom portion of the safety dam activates the power limit switch causing the power limit switch to stop comminution by the shredder cutting cylinders.
