On page 333 of the present volume of the SCIENTIFIC AMERICAN, we published an engraving of Hussey's cutting apparatus, and his claim dated Aug. 7, 1847, but we then overlooked the fact that his patent had been re-issued April 14, 1857, and we now subjoin the claim of the re-issue ;— " I claim the combination of a vibrating scolloped cutter, the indentations of whose edge act as a series of moving shear blades, with slotted guard fingers, the sides of which act as a corresponding series of fixed shear blades, tbe parts of such fingers forming the slot, being connected at the front ends only, leaving the rear of the slot open and free for the escape of material that would otherwise clog the cutter, substantially as described."
