  • Patent number: 9884323
    Abstract: An auto-feed paper shredder operates by using counter-rotating belts to grasp sheets of paper from the bottom of a stack of paper and push the sheet into a shredding mechanism. Successive sheets are pulled from the stack and shredded so that an entire stack of several hundred sheets can be shredded without operator intervention. The belts that accomplish the auto-feeding are housed in roller belt assemblies that can be easily removed from and reinserted into the paper shredder. In this way when the belts become worn and no longer effectively grasp the paper, the user simply removes the assembly and inserts a new one. The worn assemblies can be returned to the manufacturer to be refurbished.

  • Patent number: 9802332
    Abstract: A jig for profiling the end of an elongate workpiece, especially a coping or crown molding section, comprises a support for a sample to be copied, and for a profiling comb to be pushed against the sample to define a cam surface. A cutting tool can be mounted to follow a path defined by the cam surface, to cut the workpiece end to match the shape of the cam surface. The profiling comb is movable between a first position facing the sample support to form a profile and a second position in which the profile can contact the cam follower on the movable mounting. In its second position the comb extends at an acute angle to the longitudinal direction of the workpiece support, which is configured to support the workpiece at an acute angle about its longitudinal axis corresponding to the angle at which the comb is fixed.
